A nail, a piece of wooden board. When the nail was nailed into the wooden board, everyone looked at Li Chengqian for some unknown reason, and Liu Min, who was holding a hammer and had a mysterious face.

"Your Highness, what are you doing?" Old Liu looked at the nails on the wooden board suspiciously, but how could Li Chengqian stand with a smile on his head, his mind was full of question marks.

"Don't understand?" Li Chengqian swept over the old ship craftsman and pointed to the wooden board with nails: "This board is like water, this nail is like a boat. Look, has this nail been poured?"

"This, how can this be the same?" The old boatman was worried on his face, as if he was worried about Li Chengqian's IQ.

The old ship craftsman’s impression is that the nails in the wooden board can stand because the wooden board is real, but the water is different. How can water have such great power to "help" a ship? This is completely whimsical and simply unreasonable!

"The truth of the world is that one principle is understandable. You don't have to worry about whether the ship at the bottom will sink. Just make a model according to the standards." Li Chengqian was too lazy to explain to some ancient people what buoyancy is and what water pressure is. This kind of thing has no physical foundation, so it's useless to say it, and the more you listen, the more you become confused.

"But..." The old boatman wanted to say something else.

"No, this is my palace's ruler. Just do it."

A group of self-righteous guys always look at problems with their old experiences. God knows when the Tang Dynasty will achieve "modernization".

"Here!" With a strong sense of reluctance, everyone agreed.

However, compared with boatmen and others, Liu Min did not have many ideas.

Thinking of the bicycle that was originally, when the thing was just assembled, no one believed it was a bicycle that could be ridden. Two wheels were one in front and one behind, which was simply an existence that subverted the worldview.

But in the end, it was proved that this car could be ridden, not only Li Chengqian could, but everyone could.

His Highness the Crown Prince said that this is "science". Liu Min didn't know what "science" is, but he knew not to easily question the prince who had the name of "wisdom demon".

Experiences and lessons told him again and again that even if one day the prince said: People can fly in the sky, then people can fly in the sky without questioning, because even if everyone cannot fly, His Royal Highness can fly.

This idea has always existed in Liu Min's mind, and no one told him that he was afraid that others would say he was a lunatic.

But in the near future, his imagination became reality. Li Chengqian did fly, and he flew very high. Although he was not as flexible as those birds, it turned out that His Royal Highness could indeed "fly".

But this is a story later. Liu Min didn't expect that there would be that day. What he was thinking about now was how to comfort the anxious boatmen and how to make them honestly get out the ship that Li Chengqian asked for.

Five days passed slowly without realizing it, and the model of the pointed-bottom boat requested by Li Chengqian was made amid the complaints of the craftsmen.

It was a model of a pointed-bottomed blessed ship, but it was a little different from the blessed ship. This was a unique ship model in the Tang Dynasty. No one would have thought that a ship could make this look.

According to proportion, after the ship is officially manufactured, its length should be about 40 meters away and its width should be as high as four meters.

The bottom of the hull is covered with ballast stones, and there are more than twenty cabins isolated from each other on it. It is said that this is a watertight cabin, which can be used to prevent water leakage from the hull.

On the top of the watertight compartment is the cargo compartment, and upwards are the sailor compartment and member compartment.

But the boat did not have a place to install oars, which made the boatmen feel even more that Li Chengqian was joking about his slap. How should the boat without oars move forward in the water? Relying on people to push or blowing on his mouth?

"Everyone is thinking about it. After a while, I will wait for the Prince's Palace to come down, put this thing in the water and try it out and everything will be clear."

"It's easy to say. Apart from the clever design of the watertight cabin, this thing is a completely failed design. Even if it doesn't sink into the water, it will soon overturn. What else can I try?" The old ship craftsman muttered in a low voice. He kept insisting on his opinion that the ship was nothing but nonsense.

A group of shipwrecks and some people who had nothing to do to watch the fun gathered together and waited for a while, and drove into the yard from the front gate with Li Chengqian's carriage.

After Li Chengqian came down and greeted everyone, Liu Min stepped forward and asked, "Your Highness, can the experiment begin?"

"Yes." Li Chengqian looked at the model that was being carried by two men, nodded and said, "Didn't you try it?"

Liu Min glared at the old boatman who wanted to interrupt, turned to Li Chengqian and said, "Your Highness, I just finished processing last night and I informed you directly. We have not had time to try it."

"Okay, let's find a place to try whether this thing is useful or not." Li Chengqian doesn't care what the boatmen think in private, as long as they make what they want.

He was a dignified prince and went to argue with a group of shipwrecks. No matter how you look at it, it seemed like he was losing his identity. Anyway, after this model was launched, everything would be like a big deal, and it didn't matter if it couldn't be distinguished.

A group of people came out of the general and went to the moat of the inner city of the imperial city. The accompanying guards tied ropes to the bow and stern of the boat, and hung them down with force.

As the model slowly entered the water, everyone held their breath nervously, waiting for the final result.

A group of boatmen seemed particularly nervous. As boatmen, although they said that the ship would definitely capsize, when they really started the water, they still hoped that the ship could park steadily on the water.

Because this ship was built by them, no matter how strange it looks, it is like their own child.

Time seemed to stop at this moment, and the distance between three and two meters seemed extremely far away. In everyone's feeling, the guards who hung the boat into the water seemed to be doing slow motion.

Finally, the bottom of the model approached the water surface and slowly sank into the water...

Huge cheers sounded in the crowd, and people except the boatmen were clapping their hands to celebrate, as if they had encountered some amazing festival, while the boatmen looked at the ships floating steadily on the water in amazement, looking at each other with absurdity.

The pointed boat really didn't overturn? How is this possible?

I have long heard that Li Chengqian has the ability to destroy people's three views, but now that I finally experienced it personally, the boatmen realized that what was destroyed was not only the three views, but also the pride that existed in my heart since I entered this industry was also shattered!

Today I owe you a chapter because I am outside and I really don’t have the chance to write. I work hard at night and try to make up for it. If I can’t make up for it tonight, I will have four chapters tomorrow
Chapter completed!
