I'm really not doing business

Chapter 223 Shouldn't be a product of this era

The most typical case of a resource-locked technology tree is the lack of horses and iron ore in the New World, which led to the lack of even a carriage in the New World, and the lack of gold, silver and copper in the Central Plains Dynasty, and the lack of shallow coal fields that are easy to mine, generally deeper than three feet. All coal has to be mined, wells, props, drainage, ventilation, gas, etc.

Moreover, the coal field should be in the hinterland instead of the side, so the cost will be lower. The transportation cost is too high these days. For the grain of 400 million shi, Daming has to go to great lengths.

There are actually iron mountains in the New World of North and South America, but the iron mountains are too far away from the core hinterland.

The core logic of the resource-locked technology tree is actually very simple. Coal is expensive and cheap. A catty of coal costs six to eight cents, and the price of coal will soar when it rains or snows. This is enough to show that the supply is less than demand, so there is no extra coal to burn to light up the steam engine technology tree.

It's not that there is no demand, but that there is not enough coal, and every catty of coal is carried out of the kiln at a risk.

If the coal is dug out in the open air, it may only sell for a penny per catty, and if the quantity is sufficient, the coal can naturally be used to increase production efficiency, and a functioning pumping machine can be burned to increase the coal mining efficiency. Ben.

But the coal in Daming is from the kiln well, deep into the depth of forty or fifty floors underground, and the amount is very small, so it can only be saved for burning.

Tessie's steam engine was not achieved overnight. The genius inventor Watt said that if there is a steam engine, there will be a steam engine.

From the end of the 100th century to the [-]th century, the coal mining industry in England was highly developed. It was difficult to meet the needs of extracting groundwater from mines by manpower and animal power alone. The coal yards had abundant and cheap coal, and the exploration of "lifting water with firepower" And experiments began at the end of the [-]th century, and burned for more than [-] years. Only at the end of the [-]th century, Watt completely improved the steam engine and became the core driving force of the industrial revolution.

This long development process is that quantitative changes lead to qualitative changes.

Daming couldn't burn coal so extravagantly, but it didn't matter, Zhu Yijun took out silver to encourage craftsmen to innovate.

Zhu Yijun didn't intend to wait any longer, and issued an order to the cabinet that he was willing to take 50 taels of silver from the internal funds as a reward, and in the name of the Royal Gewuyuan, promote the exploration and experimentation of using firepower to lift water and find a solution.

It would take the Xishan Coal Bureau five years to earn this amount of money, but the emperor took the money directly from internal funds.

"Mother, my son went to the Xishan Coal Bureau to see that the kiln people went down to the mine with the idea of ​​five deaths and one life, and went to the kiln to dig coal. At present, the Xishan Coal Bureau uses water drainage to dig out water, which leads to water seepage in the Xishan Coal Bureau. In the whole of last year, there were 150 or 1750 water seepage incidents in the Xishan Coal Bureau, and 50 kiln dwellers died, accounting for [-]% of all deaths." Zhu Yijun is not yet in charge of the government, and the internal funds are [-] taels. Naturally, I have to explain it to Queen Mother Li.

Empress Dowager Li was born in a poor family. She looked at Zhu Yijun with a gratified smile and said, "The emperor has grown up. In Mother's view, it is the same thing as Bao Qisi, since it is beneficial to the people of the world, then do it boldly."

Empress Dowager Chen took a sip of tea and said, "The world belongs to Your Majesty, just use some silver. If Your Majesty thinks it's worth it, it's worth it. If Your Majesty says it's worth it, it's worth it."

Zhu Yijun had actually prepared a story to convince the Empress Dowagers of the Two Palaces, but he made a head start, and the Empress Dowagers of the Two Palaces directly expressed their support.

If the little emperor started to reason, the empress dowagers of the two palaces would even have the feeling of facing the officials in the imperial court. They don't need to tell stories, but they can do it boldly. Fu, the emperor is not educated well, it is all the fault of the grand master.

In the eyes of the Empress Dowagers of the Two Palaces, His Majesty can do anything with the internal funds. The palace and the world belong to His Majesty. The emperor attaches great importance to arithmetic and the theory of infinity. The difference is nonsense.

Emperor Jiajing practiced Taoism for more than 20 years, and Emperor Longqing often rewarded tens of thousands of taels of art. The courtiers all opposed it, and Zhang Juzheng even opposed it. Isn't it useless?

The power of the emperor of Ming Dynasty is unlimited, but the emperor of Ming Dynasty himself is a person who exists in a physical sense.

Zhu Yijun chatted with the Empress Dowagers of the Two Palaces for a long time, and then left after having dinner in the Palace of Compassion.

And Zhu Yijun summoned Zhang Juzheng again and asked whether this decree was reasonable. After all, it was his first edict to the craftsmen of the Ming Dynasty, and he had to confirm whether this decree was appropriate.

"I pay homage to Your Majesty, is Your Majesty safe?" Zhang Juzheng greeted.

Zhang Juzheng was very surprised by this decree of the emperor. According to past experience, the emperor who is so frugal to the point of being stingy is a bit like a brave man, who can only get in and out, but the emperor pays 50 yuan when he opens his mouth. This does not seem to be stingy What ghosts can do.

"I'm safe, sir." Zhu Yijun said with a smile: "Sir, I have listened to the government for a long time. If you understand the government order, please correct me."

"Since Mr. Chen Wushishu, I have read all the decrees, and I have found a common feature, that is, the vision, mission, and goal of this decree. The hype and flowers are written in the memorial. Everything is good, benefiting the imperial court and the poor coolies, but when the cost is never mentioned, I will immediately express my opposition."

"There is no such kind of pie in the world that is full of benefits and has no disadvantages."

"Take today's Xishan Coal Bureau as an example. Xishan has been mining coal for a long time. It has been four to five hundred years since the Jin Kingdom occupied Youzhou in the Southern Song Dynasty. In such a long time, the shallow rich ore has been mined. Go down to the deep well to mine."

"The government decree of the Xishan Coal Bureau benefits the imperial court. After all, the imperial court can use it to gather profits and benefit the poor and coolies. After all, firewood, rice, oil, salt, and firewood are the most important. The capital is cheap and firewood is expensive. As long as coal can be supplied stably, it can make the capital people take a breath."

"But what is the price? I, the three princes, and uncle Li He donated their kilns to the court for unified procurement and sales. Xu Congcheng was killed for this. This price seems to be a powerful man, but it is not entirely , in fact, there is another price, that is, the coolies of the poor.”

"To be specific, it is the kiln dwellers who went down the well. They are also the price. I can't bear to exchange their lives for coal."

Like Chen Siliu's thousands of poor coolies, they are the majority, the world is the world's people, and they are the people of the world.

The cost of this decree of the Xishan Coal Bureau is not only the sponsorship, but also the specific coal mines. The money is lost, and the coal mines are lost.

"Your Majesty is wise." Zhang Juzheng listened to His Majesty's words very seriously, and said sincerely again that His Majesty has already met all the conditions for taking charge of the government.

Emperor Regent of the Ming Dynasty did not intend to always usurp the authority of the emperor and remain a regent. Since he intends to return to power, he must carefully consider whether his majesty is competent, and now his majesty is already a wise king.

Zhang Juzheng knew in his heart that His Majesty is very wise.

During the Jiajing period and the Longqing period, Zhang Juzheng was the kind of courtier who did not please the emperor but could not be used. Zhang Juzheng scolded Jiajing for cultivating Taoism and disregarding the common people in the world, saying that it was too difficult for the Jiajing emperor to conquer the end, and it was easy to give up halfway. Compared with Longji, Zhang Juzheng relied on the cabinet to oppose the extravagance of Emperor Longqing, and bargained not to spend money on Emperor Longqing. Whenever Emperor Longqing spent too much money, Zhang Juzheng wrote a letter to oppose it.

In the eyes of Emperor Jiajing and Emperor Longqing, Zhang Juzheng was an even more annoying subject than Hai Rui. After all, Hai Rui could only say a few words, and Zhang Juzheng could actually influence the implementation of government orders.

But in the Wanli period, Zhang Juzheng, who didn't like the emperor, more often advised the emperor not to be too radical, but to be merciful.

Because the three words of being sensible are really not easy.

Take His Majesty's principle of analyzing government orders as an example. Like Monkey King, His Majesty can clearly see the other party's fundamental purpose and speak with cost and price.

This is wiseness. Zhang Juzheng said that His Majesty is wise because His Majesty is really wise.

Zhu Yijun said confidently: "According to Mr. Contradictory Theory, one matter, one decree must have two sides. Only the advantages are mentioned, and the disadvantages are not mentioned. That is, there are several possibilities."

"The first is that the invisible cost is huge, expensive, and even shakes the country, so it can only be avoided; second, the will to implement the decree comes from the supreme emperor, and it has to be implemented. Opposition has a political trend and can only be avoided. ;Third, when it is implemented, it will bear unimaginable risks and pressures, which cannot be implemented and can only be avoided."

"Still taking the Xishan Coal Bureau as an example, the cost of coal mining is the life of the powerful and the common people, and exchanging their lives for coal is the harm of the imperial court's harsh punishment for the poor coolies, and the will of the government comes from me. Coal is an unimaginable risk."

"Now that this decree is being implemented, it seems logical that I will spend 50 taels of silver to encourage the innovation of production tools and reduce the risk of kiln collapse."

Zhu Yijun first admitted that some of the wrong decisions he had made in the decree of Xishan Coal Bureau were too idealistic, and he felt that with Wang Chonggu, a courtier who made a fortune, he could make it.

That's right, it was indeed done, but the court also took the risk of the fish and meat for this. The last fish and meat, Hu Yuan, had already been overthrown by Mo Daoshi who had one eye and provoked the world of the Yellow River.

Zhu Yijun asked about the treatment of Xishan Coal Bureau, which was the same as that of the official woolen factory. That is to say, if the kiln dwellers went down to the well and never came out again, the imperial court would give each of them a pension of 20 taels of silver. Not much difference.

But the risk of Yurou Xiaomin is still there, so it is necessary to set up a bonus of 50 taels of silver to reduce the risk.

The death of a skilled craftsman in a mining accident is a huge loss to the craftsman's family and a huge loss to the multi-official factory. So reducing the loss is reducing the cost. Therefore, it is very reasonable for Zhu Yijun to encourage the innovation of production tools and technological progress. One more thing.

"Your Majesty is wise." Zhang Juzheng bowed his head again, His Majesty's analysis of contradictions has been perfected, and the lowly Confucians can no longer fool the little emperor. Reading the contradictions, it is doomed that His Majesty will think about problems based on facts. There is no need for Zhang Juzheng to worry about anything.

His mission of Ming Shezong has been completely completed.

"Sir, I have a good thing." Zhu Yijun stood up and started his performance. To be precise, he made a basic model of fire pumping water.

"This is Taixi's steam ball. It's very simple. Add water here. After heating the water, the steam enters the small ball along the copper pipe, and the small ball starts to spray out, driving the small ball to start rotating." Zhu Yijun first demonstrated The first object, the steam ball.

A three-legged airtight pot can be filled with water, and a hollow ball with two outlet pipes tangent to the circle.

Zhu Yijun lit the oil lamp under the table, the oil lamp began to heat up, and soon the small ball began to rotate slowly. When the water in the closed pot began to boil, the speed of the small ball became faster and faster, and even produced a whistling sound. The water in the water became less, and Zhu Yijun used the lid to turn off the oil lamp, and the ball slowly stopped.

Firepower, steam, rotation, and if matched with a crank, reciprocating motion can be achieved.

"It is said that Hero, a doctor of mathematics in Alexandria, invented it more than 400 years ago, but according to Taixi's statement, this thing should have appeared less than 50 years ago." Zhu Yijun explained the source of this thing.

The steam ball was first recorded in the "Mechanical Collection". The steam ball was an invention during the Renaissance, and it was only named after the sages. Even the mechanical collection is most likely created during the Renaissance.

"This steam spinning ball is the first method I thought of to lift water by fire, but this method is extremely inefficient. Come with me, sir." Zhu Yijun explained very clearly that the efficiency of steam injection is really too low.

The reason why Zhu Yijun is so sure is that he made a pot.

The shape of this pot is very unique, like a teapot, but the spout of the teapot is thin and long at the top. The spout blows to the copper blade, and the blade drives a crank to achieve reciprocating motion for grinding powder, but no matter what Attempts to blow the blades with this jet were unsuccessful.

It moved, but the movement was too slow, and the grinding efficiency was too low.

"The reason why I did this is to talk about the lights in Aoshan. Feng Daban had someone make a revolving lantern. There is a spoke on the revolving lantern. After the lamp is lit, the heat drives the spoke to rotate, and the spoke drives the lamp screen to rotate slowly. The revolving lantern , The lantern is running, the lantern is off and the horse stops." Zhu Yijun took out a palace lantern and took it apart.

On the [-]th day of the first lunar month, there was a lantern festival, and the Aoshan Lantern Festival in Daming had already been held as scheduled. Zhu Yijun still didn’t go to join in the fun in order not to reward money, but he noticed a very interesting thing, the revolving lantern.

The revolving lantern has an impeller, hot air blows the impeller to rotate, and the impeller rotates with an animation screen. This thing has been very popular in the Song Dynasty, and Zhu Yijun even got a steam pot and tried to blow the impeller.

"It's a pity that it failed." Zhu Yijun said with a little distress. He was very clear about the principle of the steam engine, but the process of exploration did not seem to be smooth. When he got here, Zhu Yijun stopped. Known technology tree, made two toys.

Without exception, are not practical toys.

Zhu Zaiyu looked at the teapot turbine and blades made by His Majesty, and became thoughtful, but Zhu Yijun didn't notice that Zhu Zaiyu was thinking.

Zhu Zaiyu, the first sacrificial wine of the Royal Gewuyuan of the Ming Dynasty, a great scientist of the Ming Dynasty, the inventor of the twelve well-tempered and compact musical instruments, the name of Zheng Wangbiao, and the uncle of His Majesty the Emperor, returned to the Qintianjian Yamen after the performance.

He thought about His Majesty's experiment, which brought Zhu Zaiyu many novel ideas, and he vaguely noticed the reason why His Majesty failed to take shape.

The speed of the ejected steam is too slow, and the ejected steam is in an open environment with only one impeller, and the impeller is not dense enough.

Zhu Zaiyu first had to solve the problem that the jet speed was too slow. How to lock the steam in a closed space, and then erupt the steam at an extremely fast speed to blow the blades became Zhu Zaiyu's top priority. Work.

Sealing is not difficult, and it can be done completely by using spirals and copper sheets. Zhu Zaiyu designed a very strange pot.

The pot weighs more than 40 kilograms and is made of all iron. There is a copper pad on the bottom of the pot cover, which is tightly sealed with screws.

In Zhu Zaiyu's design, the expansion force of the steam is strong enough to push up the iron block, and the speed of the steam is naturally extremely fast.

The first experiment failed without a doubt, and there was a roaring explosion. Fortunately, the person who started the fire was far away, and the iron pieces from the explosion flew everywhere. The four taels of iron was reduced to two taels.

In the continuous experiments, Zhu Zaiyu recorded the process in detail, and finally determined the plan of the pressure cooker.

During the pressure cooker experiment, he also made a new airtight revolving lantern impeller, and this time he added four impellers in the airtight circular impeller chamber with an inner diameter of three inches, allowing high-speed airflow to drive the impellers to rotate.

The more Zhu Zaiyu experimented, the more excited he became. In mid-February of the fifth year of Wanli, Zhu Zaiyu brought his turbine to the emperor.

"Is it so big?" Zhu Yijun looked at the red silk cloth that was two people tall and three to four feet long in front of him, and said full of doubts.

Zhu Zaiyu pulled back the thick red silk cloth and said, "Your Majesty, here are sixteen pots. The steam enters the impeller chamber through the pipes, and the impeller drives the shaft to rotate rapidly."

The steam provided by one pot is not enough, so sixteen pots are provided together. Zhu Yijun inspected the sixteen pots placed side by side. The principle of the pot is very simple. It is a pressure cooker. The air pressure in the pot is high enough that when the safety valve is jacked up, the steam starts to roar.

The impeller compartment used for the display has been spliced ​​together, but Zhu Zaiyu thoughtfully prepared an open impeller compartment for His Majesty to see. Zhu Yijun saw a very interesting thing, the bearing.

The big iron ring is covered with a small iron ring, and some copper pillars are arranged side by side on the small iron ring. These copper pillars have a smooth surface and are covered with shark oil. The four-sided impellers are fixed on the shaft.

Shark oil is a strange thing presented by Yin Zhengmao, governor of Luzon. In fact, this thing is whale brain oil, only three hundred catties, but this kind of strange thing is a natural lubricant, so Zhu Yijun saw the bearing.

The impeller of the impeller cabin has also increased from one floor to four floors. The impeller cabin is a trumpet-shaped design with a small head and a large foot. The bearing has a flywheel. As long as it can rotate, it will not be difficult to fetch water from the ground.

Zhu Yijun frowned and picked up a blade. This blade is flat, one side is flat, and the other side is a streamlined surface. This is the basic principle of a hydrofoil sailboat. The pressure difference generated by the fluid is used to drive the impeller to rotate. , rather than blowing directly.

The efficiency of direct blowing is too low.

And Zhu Zaiyu applied this technology to the impeller. The experience of hydrofoil sailing told Zhu Zaiyu that Daming’s hard sails can sail against the wind and use the wind more efficiently, so using this style of blade directly on the impeller can Effectively increase efficiency.

The densely packed impeller blades are placed in a patchwork order, making the most efficient use of the fast-flowing wind.

Yes, in Zhu Zaiyu's view, what His Majesty wants is a machine that uses wind power on land. Isn't the high-speed flowing steam a kind of wind power?Isn't the impeller on the marquee the sail of the bearing?How to use wind power more efficiently is what Zhu Zaiyu has to do.

Chemical energy is converted into thermal energy of steam, thermal energy of steam is converted into fluid energy, and fluid energy is converted into mechanical energy, which is the energy conversion of the whole process.

After Zhu Yijun checked everything, he signaled Zhu Zaiyu to start showing.

"Add water! Your Majesty, stay away for now." Zhu Zaiyu was worried about the explosion last time, and was afraid that there would be another accident this time, so he asked His Majesty to stay away.

If this thing blows up, it doesn't matter if it hurts Zhu Zaiyu. If it hurts His Majesty, there is no need to study the matter of raising water with firepower. All craftsmen involved in this matter may all be beheaded.

Retro factions, I'm afraid they will be happy to grab the ground with their heads.

Standing in the distance, Zhu Yijun looked at the monster with mixed emotions, as if a villager had shared the absurdity of controlled nuclear fusion with Zhu Yijun.

The chief scientist of Ming Dynasty did not come up with a traditional reciprocating steam engine, but a steam turbine, although it only has four floors.

"Light up the fire!" Zhu Zaiyu said loudly, and with an order, the eunuchs who had been waiting began to add coal to it. In time, the turbine began to rotate, and the speed of the flywheel changed from slow to screaming roar.

Zhu Yijun even had the illusion of an airplane taking off.

After only a quarter of an hour, Zhu Zaiyu ordered the fire to be ceased. After the turbine had completely stopped, Zhu Zaiyu said angrily, "Your Majesty, it can turn, that is, it can turn."

"I have observed that the steam will slow down every time it passes through an impeller, which makes the machine rotate slower. I am trying to solve it."

Zhu Yijun said with a calm expression: "The speed can be increased as much as it is slowed down. Between the impellers, install a fixed impeller that does not rotate in the opposite direction, and it is only used to guide the flow. Isn't that all right?"

Zhu Zaiyu's eyes widened suddenly, he clenched his left hand and slammed his right hand hard, and said with ecstasy, "That's right! Why didn't I think of that?"

Zhu Zaiyu couldn't wait any longer. Because of the reduced flow velocity, only the first impeller can take advantage of the high-speed airflow of the steam, but the airflow velocity passing through the lower three impellers will decrease, and even have a counterproductive effect. Instead of letting the flywheel speed Faster, the utilization efficiency of one impeller is higher than that of four.

But the little emperor's words let Zhu Zaiyu find a solution, how to speed up the speed of deceleration, install a completely opposite impeller, and the steam can be accelerated again.

Zhu Yijun and Zhu Zaiyu chatted for a long time. First of all, from the one-way impeller, the symmetrical design became two, which became a structure with a thin center and thick ends. The reason why the middle is thin and the ends are thick is because the pressure and volume are inversely proportional. , When the steam pressure decreases, the volume will increase, so it should be thinner in the middle and thicker at the two ends. The reason for this design is to make use of the flow rate of the steam as much as possible.

On the third day, Zhu Yijun saw the new impeller, which changed from four pieces to seven pieces. The stator responsible for accelerating the steam has three pieces, and the rotor responsible for driving the bearings to rotate has four pieces. Lubrication, the utilization efficiency is further improved.

Zhu Yijun stared blankly at the roaring giant beast in front of him, while Zhu Zaiyu was as happy as a child, looking at this, looking at that, he was bypassing the degree.

Record the wind speed of steam entering and the wind speed of the air outlet. In Zhu Zaiyu's view, the reduction of the wind speed at the air outlet is proof of further improvement in efficiency, and the time for the impeller to work stably is an urgent concern for Zhu Zaiyu.

How to further improve, add impellers, change the shape of the blades, further improve the fan size of the blades, etc., is only the first step, how to rotate more efficiently, more stably, and for a longer time is Zhu Zaiyu's idea topic.

Zhang Juzheng watched this scene in amazement, he knew that a brand new era had quietly opened.

"What's the name of Uncle Huang?" Zhu Yijun asked with a smile.

"Wanli made steam engines." Zhu Zaiyu said succinctly. The steam turbine invented and created during Wanli was the answer Zhu Zaiyu gave.

Zhu Yijun was silent for a moment and said, "Call Zheng Wangzao."

"I don't want to take over the title of King Zheng." Zhu Zaiyu said very confidently.

Zhu Yijun thought for a while and said: "Then I will give the emperor a new king? Make him King De."

"Your Majesty, King De is the second son of Yingmiao, and he has already been crowned king." Zhang Juzheng carefully reminded His Majesty that there is already King De.

"Let the name of King De's mansion be changed, and if you don't change it, you will be abolished. Anyway, my father also abolished King Liao, so he is not bad for such a King De." Zhu Yijun said with certainty, Zhang Juzheng obviously understood the meaning of this stuff, If Prince De's Mansion refuses to give in, then the feudal clan will be abolished and sent to the high wall in Fengyang.

"If I take over the title of the king, I won't be able to do business in Beijing. My ancestors are still in the law. I just want to take shelter of Your Majesty and continue to do these strange tricks." Zhu Zaiyu still refused to agree. He didn't want the king. Jue, because he became a king, he was banned and could not go anywhere. As long as His Majesty continued to support him in his work, he would be very lucky.

Looking at the roaring steam engine, Zhu Yijun didn't know what to say for a while, thousands of words merged into one sentence, Uncle Huang Niupi.

Everything about Zhu Zaiyu's machine comes from Daming's existing technology. With the power, Daming's productivity is about to make a leap.

Zhu Yijun thought for a while and said: "The emperor's uncle will come to the house tomorrow to receive 50 taels of silver. Since the emperor's uncle has conquered a real problem, I will definitely reward him."

Zhu Zaiyu shook his head and said, "If your majesty buys a horse bone with thousands of dollars and gives it to the minister, it will surely make the outer court think that it is the left hand and the right hand. The minister thinks that this is one way, and there are other ways to go. Your majesty rewards others."

"The minister is doing things with His Majesty's money, so there is no need to reward him."

Zhu Zaiyu still refused to accept the reward. The emperor made a deep investment in him. In the past few years, all his expenses in the capital included the editing and editing of mathematics textbooks, the reflecting telescope for stargazing, the calendar and astronomy students, and the staff in the inner study. Without His Majesty's full support, he would not be able to do a single thing as an apprentice and editor of the Wanli Law Calendar.

He has no money. Which of these things is not a money-burning thing?
He doesn't regret it, he doesn't regret being lured by His Majesty with a sextant to the capital to work as an ox and a horse. On the contrary, under the influence of the Ming Dynasty and public opinion, all the things he studies are deviant without exception, and must be sheltered by the imperial power , his intellect can be brought into full play.

Therefore, he named the steam engine Wanli Zao, which is a product of the Wanli period, not just his own wisdom.

Zhu Zaiyu left with a new improvement plan, and Zhu Yijun looked at the flame-out steam engine and said to Feng Bao: "Order the Ministry of Industry to build a palace for the emperor's uncle in the Royal Gewuyuan. The Gao Liji sent by North Korea, the Thai and Western women sent by Luzon, and the Hailar sent by the northern captives also need a place to settle.”

"Decree to the Ministry of Rites, the emperor's uncle should treat him with the courtesy of a prince, and there should be no slack."

"Order the Ministry of War to assign four hundred red-helmet guards to the emperor's uncle. If the emperor's uncle is in trouble, he will sit on the melon vine and will not tolerate it."

"Feng Daban, how many extravagant staff will be assigned to the uncle of the emperor. All security matters are above the prince's. The palace is responsible for all arrangements for entry and exit."

"What else can I reward? Just take out such a little thing. In the future, if I talk about it, I'm afraid I'll be scolded again for being ungrateful. It's better to give the emperor 50 taels of silver. It's more reassuring. Woolen cloth."

"A wonder."

　The reciprocating steam engine did not click the wrong technology tree, but there was no research on fluid energy at that time, so the reciprocating steam engine was in line with Taixi, but Daming had already studied hard sails.Ask for a monthly ticket, woohoo! ! ! ! !
