Hongwu Survival Guide

After everyone had a little taste of the future he had outlined, Zhu Yuan then answered some questions from Lao Zhu and the officials, and then signaled to the north: "My ancestors, Your Highness, and everyone, the last one, please move."

Came to the shore of Xiaohu Lake.

Just looking at the two large fuselages covered in red silk, everyone roughly guessed what it was.

Zhu Yuan stopped the crowd from getting too close, and stood still in front of the last demonstration board, which was two feet away, and ordered the craftsmen to uncover the red silk. Immediately, two normal-sized steam engine models appeared in front of everyone, with yellow bodies all over their bodies. It looks expensive.

The craftsmen began to pour water into the fire, and Zhu Yuan also started to talk again: "My ancestor, this is a normal-sized steam engine. Because it has just been made, it may be dangerous to operate. You can just watch it from a distance. Let me explain a few points first."

As he spoke, he gestured to the demonstration card that was also unveiled in front of him: "The first one is about the materials."

At the same time, he nodded not far away: "The main parts of the two model machines you see are made of brass, because the copper material is soft and easy to process. However, Daming lacks copper, even if it is forced to use copper, Because the cost is too high, it is not cost-effective. Therefore, in the future, large-scale steam engine manufacturing will definitely use steel materials. This is also related to what I said before, iron occupies 5% of the earth under our feet, which can be described as inexhaustible. "

This is the first time Prince Zhu Biao interrupted: "Yuaner, you said iron is 5%, how much is copper?"

"Your Highness, this really stopped me." Zhu Yuan thought for a moment, then asked back: "Your Highness, you should have read the periodic table of elements, right?"

Zhu Biao nodded, paused, and subconsciously added: "There are a lot of incompleteness."

"Yeah, I only remember the first twenty or so, and I can't remember the whole table," Zhu Yuan said with a smile, "There is a reason that the higher the element in the periodic table, the more abundant it is on the earth... There may be more. Well, it’s just possible, because, as I happen to remember, the most abundant element is 'oxygen', which ranks eighth in the table, and the first 'hydrogen' element, I don't really remember, the proportion should be very low, I What we know is that the eighth 'oxygen' and the No.14 'silicon' together account for more than 70% of the earth's mass."

Zhu Yuan glanced at the ground as he spoke. The pavement here is bluestone. For a moment, he couldn’t remember the composition. He quickly turned to the surrounding houses and pointed to them: “Your Highness, look at those bricks. They are made of clay for the second floor. Clay is called "silicate" in chemistry, and its main components are oxygen and silicon. Most of the land, rocks, etc. that you see every day are also silicates. Oh, digressing. Besides, the element ranks third It is also a kind of metal called 'aluminum', sodium magnesium aluminum silicon phosphorus, ranking No.13, I can't remember exactly what the ratio is. Because the aluminum element is very active, it cannot be refined by our means for the time being. Then , No.4 is iron, accounting for 5%..."

Facing Zhu Biao, Zhu Yuan wanted to take the initiative to talk more.However, for Zhu Biao, even if these knowledges are just some basics, he still doesn't want someone to talk nonsense.

So he took the initiative to interrupt: "Yuaner, where is copper?"

Zhu Yuan was interrupted, felt the meaning in Zhu Biao's expression, smiled and nodded slightly, and then said: "Copper... should be at the level of one thousandth or one ten thousandth, very, very few, the reason... ...Heh, it still involves some of the origins of the sun that I said in the imperial examination room last month. "

Zhu Biao also remembered that at that point, Zhu Yuan, who was eloquent and eloquent, stopped on his own initiative. Seeing that he did not blurt out with great interest this time, he was quite satisfied, but said: "You said at the time that you wanted to tell your father and father in private. I listen, why haven't you talked?"

Zhu Yuan apologized: "Your Highness, I've been too busy recently, so... I'll take the time to write it."

Zhu Biao nodded.

Lao Zhu listened with great interest, and said at this time: "Yuaner, this matter is not in a hurry. I will talk about it when I have free time. After listening to it, I feel that these knowledge are not useful now."

Zhu Yuan agreed again.

The surrounding people are a circle of fog.

What is the periodic table of elements?
What silicon?
What is the source of the sun?
However, seeing that the old Zhu's family seems to know something, everyone understands that this should be regarded as family knowledge, which can only dispel curiosity.

Zhu Yuan glanced at the standard-sized steam engine that was still burning not far away, and turned back to the "PPT" in front of him. He just said that it must be made of iron, and now he continued: "In summary, because of the material, we will make several in the future. Millions or even tens of millions of steam engines can only use iron."

As he spoke, he turned to the next page: "Let's talk about the application. What I just showed you is the usage after the steam engine became popular. In the early stage of development, I only had one idea for the steam engine, which is auxiliary. Auxiliary mining, auxiliary iron smelting, auxiliary processing. How? Auxiliary? For example, in mining, we can manufacture simple steam locomotives to transport ore out of the mine, which is far more efficient than human and animal power. We can also manufacture steam pumps to pump out the possible water in the mine. Besides, iron smelting is very difficult. One of the most important requirements is blowing. At present, we generally use human or hydraulic blowing. Of these two, one... oh, using the term I just said, the 'power' is too low, and the other is too restricted by the terrain , must rely on water. Now, with the steam engine, we can design blowing equipment based on this, which has super power and can get rid of terrain restrictions."

Turn another page: "Let's talk about auxiliary processing, this is an important point: machine tools."

Everyone look over here.

On the three-foot-square 'PPT', four sets of machine tools, which are up, down, left, and right, are clearly drawn by sketching techniques.Because everyone knows the water conservancy lathes used to make bearings on the banks of the Yangtze River. At present... just a glance, everyone roughly understands what these are.

Zhu Yuan also continued: "The machine tool actually has another name called 'the mother of industry', um... why, because in the industrial age, a large number of industrial parts, whether metal or non-metal, such as bearing balls , such as the screws that you should have seen, and even, in the future, there will be new types of firearms, especially this firearm, which will require machine tools for processing."

Old Zhu who was standing next to him smiled slightly when he heard this.

The mother of industry.

Others don't understand, but Lao Zhu knows that this should be called hundreds of years later.

However, since he dared to be called the 'mother of industry', Lao Zhu could also make a judgment that these things are really very, very important.

Zhu Yuan has already pointed to the "PPT" in front of him for a detailed introduction: "The machine tools in my imagination are mainly divided into four categories. The first one is lathes, which are used to process parts such as balls; the second one is drilling machines, which process parts with holes; The third, boring machine, processes cylinder parts, as well as gun barrels; the fourth, milling machine, processes irregular parts, such as gears. It sounds simple to everyone, but in fact, there will be no industrial products in the future. Except for these few shapes. So why do we design these heavy equipment for special processing?"

Scanning around, Zhu Yuan gave the answer: "Because of 'efficiency'."

He gestured around again: "The miniature steam machine we just saw, as well as the normal-sized model in front of us, are hand-polished and cast by craftsmen, which shows that it can be processed without a machine tool. However, pure hand-made cannot bring about the industrial age. For example, it takes a group of craftsmen several days to manufacture one cylinder of a steam engine, which is not necessarily qualified, while a milling machine may be able to manufacture dozens or hundreds of cylinders in a day, which is the gap."

When Zhu Yuan said this, Zhong He, who was not far away, motioned to him, stopped temporarily, and nodded.

Everyone saw this and looked over together.

Not far away, the two steam engines were covered by water mist, and two craftsmen fiddled with the runners respectively, and the sound of "chug chug—" suddenly sounded.

At the same time, more water vapor was ejected from the cylinder, and it quickly spread to everyone.

It was like a wonderland again.

The timid ones even took a few steps back because of this, but couldn't help but look over.

This normal-sized steam engine... or two of them working together, the movement at the same time, and that miniature steam engine... It's like an elephant walking on the ground shaking and a group of silent mice. It's really different.

Zhu Yuan looked at the large area of ​​water mist, but had some other thoughts.

However, I can't tell now.

Too much movement.

Zhong He and the others did a test before, and the steam engine in front of them had a maximum running time of more than two hours.

Impossible to do so now.

After waiting silently for dozens of breaths, Zhu Yuan gestured again, and soon, both steam engines were turned off.

When the movement stopped completely, Zhu Yuan looked at the water mist that quickly dissipated in the cold winter air around him, and said to Lao Zhu beside him: "The utilization efficiency is still a bit low. I just thought that these steam should be recycled several times. , probably... just make a few more cylinders."

Lao Zhu nodded his head, he didn't quite understand, at the moment... he just wanted to get closer and have a look.

Zhu Yuan had no choice but to stop: "My ancestor, wait a little longer."

At the same time, I also realized the mood when He Xuan blocked him a few days ago.

It is not easy for this steam engine to explode, but even if Lao Zhu is burned, today's great event will not be complete.

Lao Zhu thought about the power of the steam engine before, and stopped in persuasion. Seeing this, the others also gave up the idea of ​​going forward.

Unable to go forward, Lao Zhu looked around, pointed and ordered: "These...in the yard, move them to the palace for me, um...let's set them up in front of the main hall, the rails...you sir No need, it’s too wasteful, just three to five feet. And your demo boards, don’t pull them down.”

Zhu Yuan nodded, and persuaded again: "My lord, you can send the rest. It's not safe to make these two big ones. Also, even if they are small things, your highness should not use them at will. People come."

Lao Zhu didn't object, but glanced at his second son with distaste: "This is an important weapon of the country, it's not a child's plaything, how can we let them play with it at will."

Then he looked at the craftsmen around him, thinking of something, Lao Zhu grinned, and said in a loud voice: "Yuaner gave you a reward, and I was told by the officials again for this, I can't be petty, today everyone is 10 Two gold."

Immediately knelt down and kowtowed to thank.

After waiting for a while, Zhu Yuan took advantage of the opportunity to finish the last demonstration board, confirming from his precious 23rd generation grandson, Lao Zhu finally stepped forward, touched here, looked there, he looked very precious.

Too bad I couldn't take it home.

So he stayed here for more than a quarter of an hour, until he noticed the exhaustion in the expression of his precious 23rd grandson, Lao Zhu reluctantly drove back to the palace with the prince and officials.

Outside the gate, Zhu Yuan let out a sigh of relief as Lao Zhu and the others were sent away.

Complete!

Consummation to some prostration.

However, after today, a new era is basically finalized!

Today is not over.

Obviously too perfect, so perfect that Lao Zhu felt sorry for his precious 23rd grandson if he didn't do something.

So, just after Zhu Yuan had lunch and was about to take a good rest after tossing around for a few days, a decree came from the palace.Zhu Yuan, the Pingzhang political officer of Zhongshu Province, was conferred the title of first-rank Ronglu doctor, and rewarded ten servants, twenty beauties, and one hundred servants.
