Chang'an is far from the sea, so it is not realistic to build a ship here, even if he has the technology in hand, but he cannot practice it.

Shipbuilding, in particular, requires craftsmen with a lot of experience, and the cost of manufacturing is not low, so it cannot afford to be wasted.

Obviously, it is impossible to find such an expert in Chang'an, so he can only set his eyes on Dongcheng, the king of the water department in the Ministry of Industry.

Now all the ships of Datang are basically from here, so the shipbuilding technology should be relatively good.

In Zhao Yin's view, the experience of these people does not need to be considered, what they lack is a novel design drawing.

And that's his forte, having a system that helps him cheat, and it's just too easy to surpass the technology of other countries.

For the current Datang, the demand for ships will be very large, so it is impossible for steamships to be popularized all at once, so while studying steamships, he also wants to make sailboats, at least much faster than manpower.

During this period, Datang did not have ships suitable for long-distance travel, so it was simply helpless against the provocations of those overseas countries.

Therefore, there are two types of sailing ships at present, one is the clipper ship suitable for transportation, the speed of sailing is considerable, and it is a good choice for transporting goods and military transportation.

The other is the Galen ship, which can be used as a warship and can even be mounted on it.

These two kinds of sailing ships can cope with any weather, no matter how bad the environment, will not affect their normal operation, which is also currently impossible for Datang ships.

Thinking of this, Zhao Yin hurriedly found the manufacturing drawings of the sailboat, quickly drew them, and then walked towards the palace.

"The steamship has eyebrows?"

After seeing the drawings, Li Er immediately became interested.

This kid really doesn't make a move, and he will come in waves after waves!

"Your Majesty has misunderstood, with the current craftsmen of Datang, it is impossible to make too many steam engines in a short period of time, so before the steam engines are made, build a batch of sailboats for use!"

Seeing that Li Er had misunderstood, Zhao Yin hurriedly opened his mouth to explain the difference between these two types of ships.

"It's not a steamer, so what's the use?"

Li Er's interest suddenly decreased greatly, and he casually threw the drawings aside.

"Your Majesty doesn't know, my son-in-law has studied the ships of the Tang Dynasty, and they can't travel far at all, and they can't sail in bad weather, even if it's against the wind, they can't drive, there are too many restrictions."

Zhao Yin said confidently, "And the sailboat designed by the son-in-law will not have such a problem, no matter what the weather, it can be operated normally." ”

For these garbage boats right now, he doesn't even have the courage to go up and sit on them.

"Oh? Is this thing able to overcome the weather? ”

Li Er picked up the drawings again, with a hint of interest.

"That's right, the point is on this sail, as long as it is there, even if it is against the wind, it can be exercised by the wind."

As for the principle of this thing, he did not intend to talk about it.

One is that he hasn't had time to check the information.

Second, no matter how much he says, Li Er may not understand.

"You can do the shipbuilding business, I am waiting for your good news!"

If it weren't for a steamer, the cost would not be very large, so Li Er happily agreed.

"If all of my Datang people have such thoughts, why worry that Datang is not strong?"

Looking at the back of Zhao Yin's departure, Li Er sighed sincerely.

And this kid has no ambitions, he is just thinking about the people of Datang, and he lacks such talents in Datang.

The shipyard is not in Chang'an, but on the shore of Weishui outside the city, which is also the closest shipyard to Chang'an, and it is also Zhao Yin's first destination.

"See the colt!"

After the craftsmen of the shipyard saw Zhao Yin, they stepped forward to give a salute, their eyes were full of fire, they had long heard that as long as the craftsmen who followed the horses to work, they all got rid of the current predicament and developed directly.

"Who's in charge here?"

After nodding slightly, Zhao Yin looked around and slowly spoke.

"Little Wang Dongcheng, I've seen the horse master!"

A man dressed in the official mansion hurriedly walked over with a flattering face and bowed slightly to Zhao Yin.

"You're in charge of shipbuilding?"

Zhao Yin frowned, obviously the person in front of him didn't look like a worker, and he wasn't the person he was looking for at all.

"Master Horse, this is Liu Cheng, and he is responsible for the manufacture and production of all ships."

Seeing that his face changed, Wang Dongcheng was immediately panicked, and he hurriedly pulled a craftsman not far away over and quickly introduced him.

"I've seen a colt."

Seeing that the colt was coming to look for him, the middle-aged man immediately became a little cramped and uneasy, and even looked at Zhao Yin's gaze slightly dodgy.

"According to the drawings, use the fastest speed to build these two ships!"

Too lazy to talk nonsense with him, Zhao Yin directly handed over the drawings.

"You're not kidding, you're not kidding! How could such a ship float? ”

After the craftsman took the drawings and looked at them, his face was full of doubts.

He has been in the field of shipbuilding for many years, and has never seen a ship with such a bottom.

Normal boats are flat-bottomed, but the bottom of the boat on the horse drawings is actually pointed, and after such a boat is launched, it must not directly break the water surface and sink?

"You just have to do what I say, is there a problem?"

He really didn't want to explain too much of these academic theories to them, because it was a waste of words, and even if they said more, they wouldn't believe it, and it was not as easy as direct experiments after the production was completed.

"Yes!"

With the order, there was no longer any doubt in everyone.

After explaining, Zhao Yin turned around and left.

It's just that what he didn't know was that after he left, Liu Cheng held the drawings with a bitter face, and he really didn't know if such a boat could run on the water.

But if they don't follow the orders of the horse master, they will definitely not be able to eat and walk around.

If they follow the orders of the horses, once they enter the water and cannot drive, they still have an unshirkable responsibility, and at this moment, they are in a dilemma.

……

"Is it really feasible for you kid to study that so-called sailing ship?"

In the Horse Mansion, Li Er asked with a smile on his face, and the people below had already reflected the plan to him.

Although he has full confidence in what this kid decides, there is still a strong curiosity in his heart.

"Father-in-law, when did your son-in-law do something that you are not sure about?"

Zhao Yin didn't raise his eyelids, still busy with his own affairs.

In this regard, Li Ershen thought so, since he knew this kid, everything he made was so shocking.

Some things, even look the same, but the effect is very different.
