Flat-bottomed boats, pointed-bottom boats, sailboats, well, before Yang Qiao really went to study, he didn't expect that Li Er would have invented a steamship.

Well, because there is no need for too high speed, the ship is a ship, so the Yang family also began the development of the ship.

Do you need Yang Qiao to worry about developing a ship, and it is not a propeller, but two wheels are attached, which is some simple mechanical design, what, calculation, do you think that the original savage took a tree trunk and dug a boat out, and he had to take a computer to calculate how to dig the trunk, so sometimes, there was practice first, and then there was calculation.

"Hey, kiss, hey!"

"Congratulations Niangniang, the little princess is speaking more and more neatly."

Li Er and his eldest grandson walked slowly in front, followed by the faltering son, and then behind, naturally followed by a large group of palace maids and eunuchs.

"Guanyin, look, let the son!"

"Don't, it's better to follow that kid's idea, let the baby practice walking by herself, you didn't find that while the son is growing, this body is getting better and better, this son is the weakest body, but she is the most normal and the best."

The eldest grandson is the most normal, the best, naturally not in terms of appearance, but in terms of the health of the son, all the time, whether it is Changle or Yuzhang, the woman is not light on the son, but the more he tosses, the healthier the son, it's really weird.

"Second brother, what do you want?"

After passing a checkpoint, a checkpoint, a sentry tower on the city wall, suddenly, a group of officials appeared in front of him who were waiting for Li Er.

"Holy Lord, the ship below has been prepared, please ask the Holy Lord to review it."

At this time, the Ministry of Industry came to report.

"Well, take a look!"

Li Er nodded, and under the guidance of the eunuch, he walked to his position, while the eldest grandson and the others were watching from the side, at this time, the eldest grandson was not going forward, Li Er wanted to discuss things with the ministers!

On the city wall, there are soldiers holding flags, waiting for Li Er's order, or the order of the Ministry of Works, well, Li Er naturally will not directly give an order to a small soldier, and even, even the Ministry of Works, but this is not the matter of the Ministry of Works, so this order was given by him.

And on the side, there is also the head of the household department and the secretary of the military department, well, this water transportation, naturally, is also related to these two, naturally, and there are also people from relevant departments who have come.

And in the river below, this river is well repaired, you can stand directly on the city wall and watch, or on the wall of the imperial city, and even, after listening to Yang Qiao's suggestion, Li Er directly repaired the river into the imperial city, and can directly let the boat unload in the imperial city.

And at this time, there were several brand new flat-bottomed boats waiting in the river, well, there were two clouds of smoke on them, one was black smoke and the other was white smoke, and someone was observing the city wall on it, just waiting for the signal from the city wall.

"Let's get started!"

The Ministry of Industry Shangshu gave an order, and the soldier threw the flag a few times, and then the green flag went up and the red one hung down, that is, it was passable, well, that is, the so-called red light stopped green light.

"It's sailing!"

With the indication of the flag, there was also a shout from the boat below, and then, I saw the black smoke thickening, and then, the boat began to start slowly, if it was close, well, don't get close, someone sent Li Er a telescope, and even, even a few ministers on the side.

In fact, the control of this telescope is still very strict, so why would it be given to the enemy!

"Shengshang, the ugliest boat in front is a horse's, and I don't know what the horse thinks, he made the boat so ugly, but he can't help but put it in front, one is that it is stable, and the other is fast, which can not only raise speed, but also suppress speed."

Naturally, in this demonstration, the Ministry of Industry Shangshu heard that the Yang family had also made a steamer, so he asked Yang Qiao to ask if he could come to show it together, and even ask for advice, and even steal some teachers from Yang Qiao's boat.

However, when the Yang family's ship arrived, it disgusted him, why is this ship so ugly!

What's ugly, is he not knowledgeable, this ship with wheels, or the boat with oars, naturally how to run and design reasonably, even, this ship, not only runs reasonably, but even has an extra steam engine, well, it is a twin-engine steamer.

Jokes joke, there is no double and single shot, however, when you are in a hurry, you can also let two steam engines move together.

Also, although the sharp-bottomed ship was not developed, some iron sheets were still used on this ship, or now, the Yang family's ship is already a semi-ironclad ship.

However, this ironclad ship is not needed temporarily, one, it does not need to be a warship, and the other is a test operation around the city, so the transportation volume is not large, well, even if it is a backup, even, some simple calculations can be started.

"Holy Lord, the linkage between their rudder and the wheels is better than we have to think, you see, our ship is a little stiff in turning, but their ship is much more flexible in turning."

Yang Qiao is strong in technology, and naturally, this Ministry of Engineering Shangshu doesn't mind exposing his shortcomings.

"What about this technique, you guys?"

"Back to the saint, the horse has given us the drawings, however, I want to borrow a few craftsmen, but I didn't borrow it, the horse said, their craftsmen are not enough, think carefully, the craftsmen of the horse are really not enough, their craftsmen are all bought, but now, we all know that this technology is important, who still punishes the sale of craftsmen at will, even if it is some family of crime or something, this craftsman, first of all, our Ministry of Industry will go to select, so, now the Ministry of Industry has the existence of a slave craftsman battalion, in fact, This minister also reported to the Holy Lord. ”

"Well, this, I know, originally, there was such a craftsman battalion in the army, but now it's just picked up again and returned to the Ministry of Industry."

Craftsman, do you really not pay attention to this ancient world, if you really don't pay attention to it, then, how to win this battle, no one makes armor and weapons or anything, thinking that it can be done only by seizing it, but people don't know how to use this craftsman, so the war is over, and the usefulness of this craftsman is much less, and now, it can be regarded as inspiring Yang Qiao again.

Therefore, at this time, Yang Qiao can only train craftsmen by himself, so that recently, Yang Qiao rarely receives craftsmen from outside, and even, the ones that were borrowed before have been recruited back, and even, even if it is for some skilled craftsmen in the hands of the ladies, Yang Qiao has been exchanged for some ordinary craftsmen.

"Holy Lord, look at this ship......"

After the boat ran back and forth, Li Er and the ministers walked down from the city wall, and came to the ship, and visited carefully.

"Holy!"

"Get up, where are you Lang Jun?"

Li Er came first, naturally it was Yang Qiao's ship, the captain of this ship bowed to Li Er, Li Er also knew that Yang Qiao would not come, and he just asked casually.

"Take the lead, and explain to me the construction of this ship."

…………

"Husband, where are you?"

Well, the dock, though, at this point, the dock is only on the drawing, and it's a shrunken drawing.

"Daughter-in-law, this place, I'm just used for demonstration, you look at this drawing, this crane, in fact, it's not needed, why bother, it's just to demonstrate, these simple things, I don't say it, people sometimes can't turn that corner, you see our crane, from the beginning I used wood, to now, the person in charge of the boom, is still looking for wood everywhere to bear the force, don't you know how to work?"

"So, husband, you used steel to make this crane boom, and even this rope was replaced with an iron chain."

The daughter-in-law somewhat understood.

But it's a pity, it's a wire rope, at this time, Yang Qiao let people develop it for a long time, this wire rope can be made, but it's not durable, so it continues to consume a lot of money, but on the dock, the rope used in some places, or with thick hemp rope, and in some places, it was replaced with an iron chain, naturally, with an iron chain, the corresponding part is also used with a gear structure suitable for the iron chain.

"Come on, let the craftsmen speed up the manufacturing of the equipment on this drawing, and let the craftsmen on the dock speed up the construction, immediately, I will use it."
