I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

Liu Tan said, "I have this idea."

Lu Xuan was startled: "How will this be transported? By the Yellow River?"

Liu Tan thought about the route of the Yellow River, and then thought about the current weather, waved his hand and said, "No, no, this is no good, hey, let me ask, it's been several months, they must produce some results, right?"

Lu Xuan didn't speak, just watched him ask people to ask those Mohist disciples.

The residence of the disciples of the Mo family is basically gloomy at this time. Looking at the various models they made, they feel that none of them can meet the requirements of the King of the North.

What Liu Tan asked them at that time was river boats and sea boats. The river boats should be able to carry about 5000 people, and the sea boats should be able to carry about 7000 people.

And all kinds of supplies must be counted, which is simply a fantasy for the ship technology of this era.

And they don't know the difference between a river boat and a sea boat, and these children have never seen the sea.

After seeing Liu Tan send someone to inquire, everyone trembled, feeling that they were not far from death.

Mo Shi couldn't see them like this, so he could only say: "I don't know if His Highness has time to meet you."

The little eunuch didn't really make things difficult for them, he just said: "Wait for me to report when I go back."

After Liu Tan heard it, he laughed and said, "This is an intercession."

But he is in a good mood today, and he didn't have any hope for the children of the Mo family, he just wanted to teach them a lesson, if he really can't do it, then forget it, and he can't make people feel sad New Year's Eve.

Just when Mo Shi came over, he would just let them go with a knock. If you really want to build a boat, you can't rely on these people.

But what surprised him was that when Mo Shi came, he brought a lot of bamboo slips and documents.

He was obviously taken aback when he saw Lu Xuan and Liu Tan sitting together reading a book very intimately.

When Liu Tan saw him, he said, "Sit down, what are the things you brought?"

Mo Shi came back to his senses and said hastily: "These are some records of our recent ship design."

Liu Tan was a little surprised: "Then why are there still bamboo slips?"

Mo Shi smiled embarrassedly: "I used to use bamboo slips before, but I only discovered that paper can be used later."

"Huh? Didn't you all live in Chang'an before? Chang'an should be considered a place where paper is more common?"

Mo Shi hesitated and said, "Chang'an's paper... is more expensive than Shuofang's paper."

And the most important thing is that Liu Tan pays them salaries. In the past, they only had pocket money at most, and that pocket money was not enough to do anything. Buying paper was simply a luxury.

Anyway, they are not scholars, and it is not as easy to use bamboo slips to record the mechanism. After all, the paper is still a little fragile, but no matter what, it is just an excuse for self-comfort.

Now that they have money, of course they also want to use paper, so they just change it.

Liu Tan frowned slightly after hearing this. The price of paper in the northern border country has dropped a lot. I didn't expect it to be popular in Chang'an, but it's true. There are few paper workshops there, and Liu Tan won't be there for a long time. This workshop was handed over to Chen Ajiao, and Chen Ajiao didn't like the little money, so... If you really want to lower the price, you have to cooperate with others.

He put the matter aside, raised his chin and asked, "What did you design?"

Mo Shi said with some embarrassment: "Your Highness's request, we really can't meet it, even the current Louchuan may not be able to meet such a request."

"Large ships? No, no need for building ships. The defects of building ships are too obvious. Because they are too high, they are easy to roll over. They are not suitable for long-distance voyages. At most, they are inland and offshore. They are useless."

As soon as Mo Shi heard it, he knew that Liu Tan must have studied this aspect, so he couldn't help but smiled wryly: "But now the best ship of the big man can accommodate up to about 3000 people. Your Highness's request...really..."

Liu Tan said: "If you don't forge ahead, how can you count it as an invention? If you just want the best building boats, what else do I ask you to do?"

Mo Shi responded in a low voice: "It's useless for me to wait, I failed to meet His Highness's request."

Liu Tan laughed: "Show me your information."

In fact, he also knew that the previous request was quite high. The biggest possibility for him to build a boat was to take Liu Che out to play. He went boating on the lake before, so next time he would take him for a walk around the Yellow River.

When the latter will take a cruise, it should be very interesting to go all the way down the Yellow River and go ashore near the mouth of the sea.

Such a cruise ship does not need to be able to carry so many people, the most important thing is stability and the ability to carry cargo.

So Liu Tan himself planned to relax the conditions for them, but when he saw Mo Shi's information, he couldn't help being a little surprised.

Although these disciples of the Mo family are more cautious, they are qualified to travel alone or to go to the northern border country as the vanguard of the Mo family to explore the way. At least a lot of knowledge is very solid. He originally thought that these people did not know much about ships. Unexpectedly, they were able to produce an exploded view of the current ship, and note which parts are used for what, and then find ways to improve it.

Not to mention, Liu Tan actually doesn't know much about these things. He used to play with various ship models at most. At that time, because he liked to assemble by himself, he also had some understanding of the ship's parts. What shape, where should be installed.

And limited by the size of the model, what is assembled is just a shape, and there is no structure inside.

Liu Tan also drew the shape of the ship and some components before, and now he simply compares it to see if there is any difference.

Mo Shi, who was sitting below, saw Liu Tan pull out a piece of paper. Although he couldn't see the whole thing, he could vaguely see some outlines.

According to his understanding of His Highness the King of the North, this blueprint should have been designed by His Highness long ago.

So... Your Highness did not simply want to punish them by letting them build a ship, but really wanted to improve the ship?

For a moment, Mo Shi couldn't help but feel ashamed of his previous villainous thoughts, and at the same time, he also wanted to see what kind of ship His Royal Highness the King of the Northern Realm designed.

The things made by this Highness have always been eye-catching. The purpose of the Mohists to send Mo Shi is to squeeze the living space of the public losers, but Mo Shi has his own purpose-he wants to get it from the King of the North. inspired.

It's just that Liu Tan was fascinated by watching at this time, so he could only stare quietly.

Lu Xuan, on the other hand, was more open-minded, and moved closer to Liu Tan's side, looking curiously at him.

Because he lived in the Western Regions since he was a child, he didn't know much about boats. The last time Liu Che came to the northern border country, it was his first time to take a boat, let alone understand the structure of a boat.

It is true that Wusun Kingdom does not need a boat, but he is still very curious.

Liu Tan and him leaned their heads against each other and muttered something, mostly Lu Xuan was asking questions and Liu Tan was answering.

And Liu Tan compares the data maps of these ships with the ones he drew from the models in his mind, and feels that the shape of the ships has not changed very much. Generally, changes are accompanied by the progress of theoretical knowledge, and a deeper understanding of nature. Understand and know how to make the ship sail safely and safely at sea.

As for the cargo carrying capacity of the ship and the ability to sail long distances, it is also accompanied by the development of science and technology, to be precise, it is accompanied by the change of the power system.

At the beginning, relying on the age of manpower, no matter how much it can be changed, it will be limited, but in the age of steam, all technologies have begun to make leaps and bounds.

It's just that the steam engine can't be made by knowing the principle. It needs the development of the whole industry and more refined processing.

It's not impossible to make it by hand, but even if it is made in that way, it will be reduced to aristocrats, or even just a toy for the royal family.

Because it would be too expensive to build one.

After reading it, Liu Tan handed his blueprint to Mo Shi and said, "Look at it."

Mo Shi nervously wiped the sweat from his palms with his clothes, stretched out his hands and respectfully took the thin piece of paper, his attitude was so pious that Liu Tan felt a little embarrassed.

The other ship information has basically been entered into his mind by Mo Couture, so at this moment, as long as he looks at this blueprint, he can immediately compare it with his own blueprints.

After Mo Shi finished reading it, he hesitated and said, "Your Highness, this boat... has no oars or oars, how will it move forward?"

Liu Tan: ...

Well, he said that something seemed wrong.

When he was playing with the model, the ship had long been relying on combustion power to propel the propellers. Where did he need to leave a place for oars on the hull?

But this era doesn't have that kind of motivation, and he can't conjure up a steam engine and propeller. The most important thing is that even if he knows the principle, these two things will take a period of research and production to produce.

Liu Tan coughed lightly: "This is my negligence, you only need to look at the shape of this drawing, and this is just my creation, it is not perfect, what you need to do is to absorb experience from it to improve. "

Mo Shi didn't believe what Liu Tan said.

There is a complete shape diagram of the ship on the blueprint, both from the front and from the top view, and it looks very complete and harmonious.

As a machine engineer who has been immersed in machine skills since he was a child, Mo Shi may not understand many scientific theories, but he is born with an aesthetic appreciation for machines.

The boat has smooth lines and all parts fit together perfectly. It is definitely not a random drawing.

Mo Shi even felt that there should be a real thing for this thing, because if it was just a design drawing, there would definitely be some places that would be uncertain and would be marked out, but the King of the North showed absolute confidence in the drawing.

He smiled at Liu Tan and said, "I know."

Looking at his expression, Liu Tan felt that something was wrong, but he didn't want to continue entanglement, so he just asked, "By the way, speaking of the driving method, why didn't I see the sails for the boat you designed?"
