Several desks were put together, and on the desk, a sallow drawing was lying quietly. And this drawing is naturally the drawing of the giant warship that Liu Shun's ancestors studied, and everyone was shocked when they saw the structure of the giant warship painted on this drawing. Even Yuan Chang, a traverser, was deeply shocked.

According to the drawings envisaged, after the giant warship was built, it was 100 meters long and 40 meters wide, which is really unimaginable.

In this era, the shipbuilding industry in Koto is the most developed. However, even in the land of Jiangdong, the largest warship is only about 20 or 30 zhang, and according to the current calculation of 2.2 meters per zhang, that is, between 40 and 60 meters. However, the ancestors of the Liu family were already thinking about building a 100-meter warship more than 200 years ago, and I have to say that this is a very crazy idea, and it is also a concept that is ahead of its time.

Historically, Sun Quan's navy has reached Singapore, Malaysia, Taiwan and other places, and the largest warship of Sun Quan's navy at that time was only more than 30 zhang, that is, about 70 meters. There are also treasure ships when Zheng He went to the West in the Ming Dynasty, and there are also twenty or thirty zhang, and one zhang in the Ming Dynasty is about three meters, that is, about ninety meters. However, don't forget, when Zheng He went to the West, it was more than a thousand years since the current era, and with the technology at that time, it was not too difficult to build the treasure ship that Zheng He used to go to the West. Now, more than 1,000 years ago, it was extremely difficult to build such a huge warship, and it was extremely difficult in all aspects, and there is no doubt about this.

Moreover, the warships of Sun Quan's navy and the treasure ships of Zheng He's voyage to the West were mainly made of wood, and a very small part of them were made of iron. However, more than half of the hull of this giant warship that Liu Shun's ancestors thought about was made of iron, and a small part of it was made of wood. Even in the Ming and Qing dynasties, most people did not know that iron could float on the water, but Liu Shun's ancestors thought of using iron to build ships. Either Liu Shun's ancestors were also a traverser, but this possibility is too small. If he is a traverser, then he should know the fate of Liu Ju, and will not befriend Liu Ju; if he is not a traverser, then it can only be said that Liu Shun's ancestors were a prescient and wise man who was rich in creativity and could accept new knowledge. If so, then that's the past.

If the giant warship on Liu Shun's drawings can be built, it will definitely go down in history, and people in this era may think it is unlikely, but Yuan Chang knows that as long as there are enough manpower and financial resources, it is not impossible to build such a giant warship.

It stands to reason that Liu Shun's ancestors have such an idea, which should be recorded by history, but why is there no voice in history?

On this point, I have to say that there are too many coincidences.

First of all, Yuan Chang crossed over, with lofty ambitions, caring for the people, benefiting the people, and being a good lord who served the people wholeheartedly (well, don't blow it too much). Therefore, Yuan Chang does not just want to fight the world and conquer cities and land, Yuan Chang is more concerned about promoting social progress. Therefore, Yuan Chang's subordinates recruited were not only generals and strategists, but also all kinds of skilled craftsmen and technicians. So, Ma Jun, an inventor in the late Eastern Han Dynasty, was invited by Yuan Chang. The arrival of Ma Jun was the opportunity for this giant warship to surface.

If you look at the trajectory in history, Ma Jun did not come to Yuan Chang's hands, and Ma Jun did not know that he was going to find the craftsman of the warship. Then, Liu Shun may have become Ma Jun's memory. However, history changed because of Yuan Chang's arrival, and Ma Jun became Yuan Chang's subordinate. Then, Ma Jun knew that Yuan Chang was looking for craftsmen to build warships. When Liu Shun ran from Jiangdong and passed by Bohai County, he was seen by Ma Jun very coincidentally, and then, Liu Shun, who had no suspense, was recommended to Yuan Chang, and then the idea of a giant warship surfaced.

It seems that an invisible hand is manipulating, making what was originally unreasonable also reasonable.

"I'm damn it, this warship is going to scare me to death!"

Dian Wei patted his chest, as if he was out of breath.

"Lord, can such a big warship be built?"

Zhao Yun looked at Yuan Chang, also full of doubts. If Yuan Chang said that he could create it, then Zhao Yun would definitely not have the slightest doubt. However, now that it was said that it was a stranger who could build this giant warship, Zhao Yun had to be suspicious. If it weren't for understanding Yuan Chang's shrewdness, Zhao Yun would have doubted that Liu Shun had come to deceive Yuan Chang.

Yuan Chang smiled silently, this guy was obviously pretending to be forced again.

Guo Jia knows that there are capable people in every industry, and he is very confident when he gives advice. However, let him get in touch with shipbuilding, Guo Jia could only shake his head. However, since Liu Shun's ancestors would have such an idea, it is naturally possible to create it. Of course, Guo Jia still had a little doubt, and at the moment, he asked it.

"My lord, according to the design on this drawing, this giant warship is made of fine iron, can something made of iron be launched?"

The perception of people in this era is that things like wood can float on the water, and things like iron make him float on the water, isn't that a joke? This question is a question that many people have, even Liu Shun has such a question. Liu Shun just inherited the concept of his ancestors, and what he really knows is not detailed. Perhaps, only the ancestor of the Liu family, who was the first to propose to build a warship with iron, knew that iron products could float on the water.

"Smack!"

Yuan Chang snapped his fingers coquettishly, pointed at Zhao Yun and Dian Wei and said, "Zilong, you go and fetch a basin of water; ”

"Yes!"

Seeing that Yuan Chang was about to perform again, Zhao Yun and Dian Wei immediately ran out after responding. A moment later, Zhao Yun came with a basin of water in a wooden basin, and then Dian Wei also brought a bunch of iron pieces. Seeing Dian Wei's actions, everyone was a little puzzled, what are you doing with so many pieces of iron?

Then, Yuan Chang put the water on the desk, took a piece of iron, and put it in a wooden basin, and in the expectant eyes of everyone, he only saw the iron piece floating quietly on the water and did not sink.

"Wow, it's really floating!"

Dian Wei exclaimed, waking up everyone who was amazed in their hearts. Then, everyone saw that Dian Wei also took a piece of iron and put it in a wooden basin, and the iron piece also floated and did not sink.

"Haha, I thought it was the lord who played some tricks, but it turned out that he could really float!"

Now, everyone finally knows why Dian Wei is holding so many pieces of iron, and his feelings are because of this reason. However, Dian Wei was really happy for a while, and then he was dragged to the corner by Yuan Chang for a profound teaching, and then, under Dian Wei's extremely sincere self-examination, Yuan Chang let Dian Wei go.

"It's amazing, I didn't expect iron to float on water. Zhao Yun said with emotion.

Liu Shun also nodded thoughtfully, "That's right, the ancestor proposed to build this kind of giant warship, I thought it was just an impulsive idea." Earlier, I almost burned the design drawings that had been handed down, but now I'm glad I didn't. Otherwise, the ancestors in the underground are afraid that they will be so angry that I will crawl out. ”

Guo Jia listened to Liu Shun's words, nodded with a smile, then looked at Yuan Chang and asked, "Lord, what is going on?"

Everyone knows that the only one who can give the answer is Yuan Chang.

"It's terrible to be uneducated!"

Yuan Chang said something very stinky, and everyone was speechless for a while, but they didn't refute Yuan Chang. First of all, they really don't know the mystery, and it is not a big deal to be said by Yuan Chang; secondly, now that Yuan Chang feels good about himself, if he refutes Yuan Chang and disturbs Yuan Chang's interest, he may be remembered by Yuan Chang, so he still silently takes Yuan Chang's disdain; finally, it is only Yuan Chang who knows the mystery, and the curiosity in their hearts at the moment has been fished, and they all want to know what is going on. It's like two little kids playing house, a boy sees that the girl doesn't have a little JJ, and the girl sees that the boy doesn't have a little BB, and they're all curious. After going home, he naturally went to his respective adults for verification, so the boy was beaten by fat, and the girl was warned to stay away from Xiao Ming next door.

Okay, to get back to the point, Yuan Chang saw everyone's eager expressions and satisfied expressions, cleared his throat, pulled up his sleeves, and just like some teachers, with an expression that I want to transform.

"You all think it's weird that pieces of iron can float on water, and that's not surprising. In your opinion, it is reasonable for wood to float on the water, but it is not reasonable for a piece of iron to float on the water. In fact, just give a simple example to see at a glance, if you think, why did the person die floating on the surface of the water instead of sinking into the water?"

Although the example given by Yuan Chang is very vulgar, it is very reasonable. Why do people float on the water instead of sinking into the water when they die? If we think about it in this way, isn't it possible for anything to float on the water?

"Very well, it seems that you have already got a little bit of an idea. ”

Yuan Chang nodded, and then said, "If there are certain circumstances, anything can float on the water. Even a knife or a gun can do it. However, these are special circumstances, and we don't need to care, what we have to understand is why things can float on the water! Speaking of this, I am more sad, because in Peter's hometown, they have long understood the principle, that is, Peter's hometown, in some respects, is much more advanced than us. In that unknown part of the world, their social system is actually backward from ours, but they can do what we can't do, not because we are inferior to them, but because our minds are not as open-minded as theirs. We have enough people, but the people who can learn knowledge are those nobles, dignitaries, and nobles, and it is very difficult for ordinary people to learn knowledge. However, in that area, they did not have so many restrictions, as long as they wanted to learn, they had the opportunity, and moreover, in our land, the most Confucian culture was the most, and I do not deny that Confucian culture has advantages. However, the downside is that no one dares to say it, which is very sad. And in that area, they have many cultures, which can be competed and discussed. Now I am not saying this to criticize Confucian culture, but to tell you that we still have a long way to go, and we need to work hard to change the land we live in, and maybe one day, when we get out of this land, we will find out how big the world really is. ”

"My lord, we will definitely work with you!"

After listening to Yuan Chang's words, everyone shouted in unison, only to feel that there was a sullen breath in their chests to vent. Yuan Chang's ambitions are ambitious and challenging. However, none of the people present were worried, as long as they followed Yuan Chang, they would be able to see hope and the future.

"Okay, now that we've said the whining, let's move on to how things can float on water. To put it simply, anything is able to float on the surface of the water because of buoyancy. Any thing that is immersed in a liquid or gas will be subjected to the force of the liquid or gas that is vertically lifted upwards is called buoyancy. Objects immersed in liquid will float on the surface of the water when they are affected by buoyancy, while objects immersed in gas will rise into the air. Well, I know it's hard for you to accept this about gases, but when I get a chance to show you something, you'll understand. ”

When it comes to things being able to hang in the air, although everyone believes in Yuan Chang very much, they still look at Yuan Chang with an idiotic look. For this, Yuan Chang was annoyed. However, Yuan Chang can also understand. What is floating on the water is relatively easy to understand because it can be seen. However, hanging in the air is more difficult to understand, because no one has ever seen it. At the moment, Yuan Chang will not continue to explain, sooner or later, let them see and understand.

"The discovery of buoyancy is actually quite unexpected. In Peter's hometown of Rome, there was an emperor named King Henon, who asked a goldsmith to make him a crown of pure gold. Although the crown weighed as much as the gold the emperor had given him, King Henonon suspected adulteration by the goldsmith. As a result, King Henon asked Archimedes, a wise man in Rome at the time, to determine whether the crown was pure gold, but could not destroy it, which seemed impossible. While returning home to take a shower and soak in the bucket, Archimedes noticed that his arm was floating on the water. Then a vague thought flashed through his mind, he put his arm completely into the water and relaxed, and then his arm floated to the surface again, and he stood up, and the water level around the tub dropped, and when he sat down again, the water level in the tub rose again, and he lay down in the tub, and the water level became higher, and he felt that he was lighter. When he stood up, the water level dropped and he felt heavy. It must have been the upward buoyancy of the water on his body that made him feel lighter. Archimedes then placed a stone and a block of wood about the same size into the tub at the same time and immersed it in the water. The stone sank into the water, but he could feel it lighter. Moreover, he had to press down on the block to completely submerge it in water. Through this discovery, Archimedes finally identified whether the crown was pure gold for King Henon, and thus discovered buoyancy, and the Roman people named the buoyancy achievement he discovered in honor of Archimedes' achievements in honor of Archimedes' law. What do you understand about this?"

"My lord, I know that this incident tells us to always pay attention to the things around us, and maybe we will find out. ”

Dian Wei was the most active, and as soon as Yuan Chang finished asking, he answered. As for the others, they are still thinking about whether there are other deep meanings in Yuan Chang's words.

"Hey, sure enough, I know you guys can't think of anything deeper. ”

Yuan Chang shook his head, sighed and said a word, then his eyes swept over everyone, his face was straight, and he said word by word: "Tong guò this matter, sue us, you must not cut corners for the emperor, otherwise, your life will not be guaranteed!"

"Plop!"

"Plop!"

After listening to Yuan Chang's words, everyone fell to the ground, and then, everyone looked at Yuan Chang with a "grudge" on their faces, except for people like Yuan Chang, who else would think of this?

"Ahem!"

Yuan Chang couldn't stand everyone's eyes, and quickly changed the topic and said, "Okay, let's move on to business." As you all know, a boat made of iron can be used on water. In addition, boats made of wood can usually only be used in rivers and lakes, and if they are placed on the sea, it is very dangerous, and it is safest to use them in the sea only if they are made of iron. Therefore, we must research and build this kind of giant warship, and in the future, who can match us on the sea?"

"Well, what the lord said is very true. ”

Guo Jia nodded thoughtfully, but Guo Jia asked again: "Lord, the power of this warship is indeed very great, but can such a warship move by oars?"

Indeed, a warship made of iron could not be shaken with oars, and it had to have other power. And the reason why Liu Shun's ancestors didn't take it out was also because of this reason, they built a warship, but they couldn't even move, what is the point, if you say it, wouldn't it be a joke?

However, don't forget, who is Yuan Chang? That's a new era of traversers, and the question of power is not a problem.

"Haha!"

Yuan Chang laughed loudly and said, "Fengxiao, as long as this warship can be built, I can make him move." However, this matter is also related to Deheng. ”

Ma Jun immediately smiled bitterly and shook his head when he heard this, how could he have the ability to make such a warship move, Yuan Chang overestimated him.

"My lord, there is really nothing I can do about this. ”

Yuan Chang waved his hand and said easily: "Deheng, you don't have to worry about this, I have an idea to make this warship move." However, I just have an idea, and it's you who really does it, so this matter must be done with the cooperation of you and Nanbao. ”

Yuan Chang's idea was naturally to get the steam engine out. With current technology, a steam engine can still be built. As for the higher-end internal combustion engine and diesel engine, I'm afraid it will be a little difficult. Moreover, Yuan Chang now controls the power of Bohai County, and he wants money, money, people, and sufficient conditions, so how difficult can it be to build a steam engine? Yuan Chang knows the structure and manufacturing method of the steam engine, but he can't do it in real hands, so he still has to build it with Ma Jun and Ou Nanbao.

When Ma Jun heard this, he immediately arched his hand and said: "Since your lord has a way, his subordinates should do their best." ”

"Okay, we are united, we must build warships, control the sea in our hands, and let our people become the overlords of the sea. ”

"Yes, my lord!"
