Daqin: When I return from sea, I will offer you a map of the world

Chapter 384: Steel smelting, firearms and gunpowder.

Although Zhao Si's words were beautiful, Liu Pi knew in his heart that there was no reason not to take this job.

Zhao Si attaches great importance to the craftsmanship bureau. Almost half of the experimental office space alone was moved out of the Aviation Trade Military Mansion, and the funds were directly given to 50 taels of silver.

The leaders have paid so much attention to it, but you say you can’t take it up?

Liu Pi spoke without any hesitation: "Please give me a try, how far can you go with steel smelting and gunpowder firearms?"

"No hurry, let's get iron, charcoal, saltpeter, sulfur and stone first."

Within a moment, a Mohist disciple brought what Zhao Si needed.

"This is iron now."

Zhao Si raised the iron plow and knocked it hard on the stone, and it broke into pieces in an instant.

"Today's iron tools are difficult to use in agriculture, and they cannot be used for weapons and weapons. They are far inferior to bronze tools. However, although bronze tools are useful, there are too few copper mines. They must be used to cast coins, weapons and armors. Raising ritual utensils is no longer enough to meet the needs of the country. Although the iron utensils are inferior, the iron ore is far more than the bronze ore. Nowadays, the Qin Dynasty has a money shortage, but the gold utensils needed for daily life are far from insufficient. Solving the problem This problem is urgent, either to find more copper ores that are easy to mine, or to replace bronze with iron.

However, since bronzes were used by people, and since the Shang and Zhou dynasties, copper mines have been exhausted. Although there are copper mines overseas, the transportation cost is too high, and the quantity is not enough. For Da Qin, which has 2000 million common people, there are only It can be a drop in the bucket.

It's just that it took nearly a thousand years of smelting technology for bronzes to reach this point. It's not difficult to catch up in a short time. It's not just smelting, but also iron ore mining. All kinds of things are involved. Innovating the old and bringing out the new, 15 The two taels of silver is just the initial investment. I have only one request, 15 taels of silver. I want you to produce iron tools that can be used in agriculture! "Zhao Si said.

Today's iron tools are only used to a certain extent among the people, and they are still very few.

Too brittle and unusable.

Even if it is used to make farm tools, it is a bit awkward. Zhao Si does not expect to spend money today and tomorrow the ironware will catch up with the bronze.

That's nonsense. The bronze craftsmanship of the Qin Dynasty has reached its peak. It was not until the Southern and Northern Dynasties that iron wares could compare with the bronze wares of this era. It was not until the Sui and Tang Dynasties that iron wares surpassed the bronze wares of this era in all aspects.

Since the Qin Dynasty, bronze ware has developed over a thousand years, but the use of iron ware is still extremely primitive, and it is impossible to catch up in just one or two years.

However, there is no need to completely surpass bronze wares. In fact, if iron wares can reach the craftsmanship level of the mid-Han Dynasty, iron wares can be fully promoted to replace bronze wares.

There is no other reason than the large quantity.

The larger the quantity, the higher the proportion of army armor.

Due to the scarcity of raw materials, the original armor rate of Da Qin's army was perhaps only one tenth.

But if you switch to ironware with rich raw materials, although the quality has dropped a bit, the armor rate can be doubled. Which is better or worse is a matter of benevolence and wisdom.

And not to mention the folk demand for metal...

Liu Pi nodded and waited for Zhao Si's instructions on gunpowder firearms.

"Gunpowder...how do you say it?"

Zhao Si thought for a while and decided to mix the gunpowder himself.

Zhao Si's knowledge of gunpowder was limited to that widely circulated jingle.

One sulfur, two nitrates and three charcoals, add some sugar and big Ivan.

Sulfur exists in nature and can be picked up in the mountains. It is also one of the main raw materials for alchemy by cultivators in this era.

Needless to say, saltpeter can be produced from dry toilets and bird droppings. There are also saltpeter mines in Daqin, but they are not easy to mine. The main source of saltpeter is to scrape toilets.

Not to mention charcoal.

Zhao Si made gunpowder strictly according to the ratio of the jingle.

It was nothing more than grinding ink into powder and directly wrapping it in paper. Zhao Si was not a hands-on expert. He just wanted to let them know the concept of gunpowder. He couldn't even twist out the fuse.

After wrapping the powder-like gunpowder in good rice paper, Zhao Si asked Liu Pi to make a fire.

Then he carefully put the paper bag into the fire.

"Everyone, stay back! Stay away!"

Zhao Si knew the danger of gunpowder and led everyone to retreat.

Everyone looked at the fire with anticipation in their eyes.

boom!
Liu Pi was startled by a big flower.

At that moment, the fire exploded.

But that’s where it ends…

There was no explosion as expected, just a big flower.

"I damn well know that sulfur, dinitrate, and charcoal are not as simple as one to two to three..." Zhao Si smiled slightly awkwardly as he looked at the people who had retreated more than ten steps away.

"This is gunpowder..."

Zhao Si originally thought that he could still explode if he strictly followed the jingle, but it turned out that he didn't explode at all, he was just a big fan, and the situation was a little embarrassing.

"Perhaps my ratio is not right... In short, these three things can explode when mixed together in the right ratio..." Zhao Si scratched his head.

Everyone gave Zhao Si a lot of respect. Even though he was a big talker, he still listened attentively. Liu Pi even took notes while listening.

"Sir, can you let me have a try?"

At this moment, a voice sounded, and Zhao Si turned around and saw a young man with a dull face but bright eyes, full of wisdom at first sight, looking at him.

Zhao Si remembered that this young man had participated in papermaking before, liked to study wooden kites, and was committed to replicating the clumsiness of Mozi's flying wooden kites.

Zhao Si nodded, and without any hesitation, Zhuo stepped forward to grind and mix.

Zhao Si noticed that Zhuo even made a simple fuse. Compared with Zhao Si's simple big flower, what Zhuo made looked more like an explosive bag.

Fire!

Peng!
This time, it really exploded.

Although the explosion range is not very large and the power is lackluster, except for the loud sound, it is still difficult to put into battlefield use, but one thing that is certain is that the gunpowder prepared by Zhuo is obviously closer to the correct ratio.

"When did you study it?" Zhao Si looked at Zhuo with surprise in his eyes.

"Shangqing forgot? When Shangqing gave the book, it said gunpowder, monosulfide, dinitrate and charcoal. I tried this ratio, but it couldn't explode as Shangqing said, so I studied it for a while, but now The gunpowder produced is still not enough for military use." Zhuo scratched his head with a smile on his face.

"Then make it more precise and detailed!"

"Look, gentlemen, if the gunpowder is mixed with iron pellets, sand and gravel, wouldn't it be able to cause effective damage when it explodes? As for the firearms I mentioned, that's based on this!"

Zhao Si squatted on the ground and drew the prototype of artillery and muskets.

This thing doesn't need to be explained too deeply, and Zhao Si doesn't explain it deeply. He has the knowledge in his head, but Zhao Si can't yet explain it in a simple and profound way based on the knowledge in his head.

Zhao Si pointed at the artillery painted on the ground and said.

"Built-in gunpowder, loaded with projectiles, the gunpowder explodes, and the projectiles are fired accordingly, shooting straight out along the barrel, instead of being broken into pieces and unevenly oriented.

What you have to do is to make the projectiles shoot farther, in a more precise direction, and with greater power! "

The current gunpowder, which is as powerful as firecrackers, would probably be enough to shoot through a cannon tube.

But what did Zhao Si provide?Ideas and development direction, this is the most valuable thing.

The field of scientific research has always been a messy exploration, with countless directions going hand in hand, and finding a correct path.

The appearance of Zhao Si meant that they avoided a lot of useless efforts from the beginning, and gave them the best and most correct direction to maximize their efforts.

This is the most precious thing!
And it just so happened that the craftsmanship of large bronzes in this era was sufficient.

If nothing else, the bronze cannon can definitely be produced.

There is no problem with the bronze smelting process, and the strength can definitely keep up. The biggest difficulty lies in the power of gunpowder.

As long as the power of the gunpowder can be increased, the cannon can be rolled out in minutes.

If we put it in the Han Dynasty, which experienced the chaos of the late Qin Dynasty and lost the bronze craftsmanship, then after getting gunpowder, the bronze smelting craft would have to be re-established.

Everyone present is a scientific research talent, relatively speaking, both in terms of receptive ability and imagination, so even if Zhao Si is giving a speech without physical objects, everyone present is listening with interest.

Top scientific research talents like Zhuo can even draw inferences from one instance and raise issues that Zhao Si ignored.

Zhao Si simply talked with these first batch of scientific research seedlings in Da Qin for a whole day.

Without him, these are still one of the few top talents who can match Zhao Si's brainwaves in this era, and even sometimes make Zhao Si himself speechless.

When Zhao Si mentioned the imagination caused by various things in future generations, their first reaction was not to question, but to think about the possibility of turning their dreams into reality.

The fantasy in the mind is no longer based on speculation about gods and ghosts, but on the prediction and summary of the development of objective laws of things.

This is perhaps the biggest difference between science fiction and fantasy.

At the end of the day, both Zhao Si and this group of scientific research talents have gained a lot.

Zhao Si appointed Liu Pi to be fully responsible for the update and iteration of steel smelting technology, and Zhuo to be fully responsible for the research and development of gunpowder firearms, and gave them the right to freely dispatch manpower in the Aviation and Trade Military Mansion. If there were insufficient craftsmen, they could directly fight with Zhao Si. The report was sent to the General's Office to directly assign people to participate in the work.

At the same time, the internal knowledge system of the Craftsman Bureau has also begun to be formally sorted out. All known theories will be compiled into volumes for study records.

The advice Zhao Si gave them was not too much.

Regarding steel smelting, all Zhao Si knows is that raising the temperature, removing impurities, and the carbon content will affect the strength of steel to a certain extent.

He handed over everything he knew to this group of talents. Zhao Si knew very well that he was just a carrier of knowledge, and it was difficult for him to apply what he learned. However, the knowledge that was limited to high school in his previous life fell here. In the hands of a group of people, it may bring about unexpected changes.

The craftsman made the final decision, and finally the work is over.

On the other side, Chen Sheng and Wu Guang also came to the bank of the East China Sea.

They received Zhao Si's order while supervising the migration of nobles.

So after some discussion, Liu Bang and Lu Wan continued to be responsible for supervising the movement of nobles into the pass, while Chen Sheng and Wu Guang led some people to rush to the East China Sea to carry out Zhao Si's order.

Theoretically speaking, Zhao Si was not qualified to give direct orders to Chen Sheng and Wu Guang. Zhao Si's instigation of Chen Sheng and Wu Guang was considered to be ultra vires.

But politics are not black and white. Chen Sheng and Wu Guang have very senior qualifications in Heibingtai. They are not small figures. Their rank is as high as two thousand stones. They can also be regarded as people with the same salary as Zhao Si. Their status is not superior or inferior, but equal.

They are all leaders, so there is no such thing as instigating or not instructing.

It was nothing more than giving some small hints, and Chen Sheng and Wu Guang discovered the clues based on the hints.

Chen Sheng and Wu Guang have the right to act independently.

"He spreads benevolence and righteousness, praises justice all over the world, and everyone praises his virtues at that time. This Lord of the Canghai has such a great reputation!" Chen Sheng said while looking at the investigation report on the case table in front of him.

Black Ice Platform has branches all over the world. Due to the short establishment time, it does not involve too much secret information for the time being, but it can always avoid the situation of being blinded by a smear of darkness in one place.

For example, now, Chen Sheng and Wu Guang knew that Lord Canghai was well-known on the banks of the East China Sea, and that Lord Canghai was not a native aristocrat of the Central Plains, but a filthy man and his former ruler.

"A filthy man can make the nobles on the shores of the East China Sea recognize his reputation and honor him as a king. It seems that this Lord of Canghai is also a man with stories." Chen Sheng had a playful smile on his face.

well known...

In the Qin Dynasty, what did a place have a good reputation meant?

After all, public opinion in Qin has always been at a disadvantage. Those who can become famous all over the world usually have evil intentions.

"A person like this would indeed hide an assassin secretly. The assassination by Bolangsha and the pursuit by thousands of soldiers could allow Zhang Liang to escape, and even become famous for a while, without the help of others. I am I don’t believe it.” Wu Guang nodded.

"If you ask me, if you are so famous all over the world, you can catch him with certainty." Chen Sheng spat.

"What kind of hereditary nobles are there who are so benevolent and righteous that everyone just praises them?"

Perhaps because he stayed in Heibingtai for too long, Chen Sheng's behavior and personality became more and more extreme.

After all, he really couldn't sympathize with this group of people from the world, and the Black Ice Platform was directly under the imperial power and was the emperor's eagle dog. Therefore, this historical rebel leader's loyalty to the First Emperor and the Great Qin continued to grow.

The more he does things, the more he understands what the world is like.

If you kill too many people, and if you watch the nobles of Shiqing and Shilu cry too much, you will realize that it is just that.

"Go to the county government to mobilize troops and arrest people!"

Chen Sheng waved his hand.

"Aren't you going to do an inspection?" Wu Guang was stunned for a moment, why didn't he just show off?
"What are you inspecting? We are rushing back to Xianyang!"

Arrest first and then interrogate!

Therefore, after Chen Sheng and Wu Guang mobilized their troops, they went straight to Canghaijun's residence.
