"Your Majesty, since the horse master entered Chang'an, it is like a divine soldier descending from the sky, there is nothing that the horse master can't solve, presumably it is your emperor's grace, so God sent such a strange man as the horse master to assist the Tang Dynasty."

Wang De hurriedly accompanied the smiling face.

Such a good opportunity, he must not miss it, not only to please the horse, but also to pat His Majesty's fart, killing two birds with one stone.

Since Zhao Yin entered Chang'an, he has done too many incredible things, even if it is something that everyone does not recognize, as long as he says yes, then he will definitely do it, and he has never broken his word.

He also used many actions to silence all those who doubted, and even made those who did not approve of him pay a terrible price.

"Your Majesty, since you are not at ease, why don't we do an experiment and make a model out of a small piece of wood?"

There is no need to ask, Zhao Yin also understands that the shipbuilders must not have started construction yet, otherwise, Li Er would not have taken the initiative to come to the door today.

"Model?"

Li Er was a little puzzled and didn't quite understand what it meant.

"It's a miniature version of a boat, a small sailboat made out of simple wooden blocks."

Zhao Yin explained while gesturing with his hand.

"Okay, let's try!"

After hearing Zhao Yin's explanation, Li Er instantly understood what this model was.

Now, all the craftsmen are questioning the kid's drawings.

Although he had always believed in his heart that what this kid had made up was fine, it would be great if he could use a model to illustrate the problem now.

"Then go to the shipyard! Where there is more wood, there is also more wood suitable for shipbuilding. ”

Although Zhao Yin said this, in fact, his main purpose was because there were more craftsmen in the shipyard, and they all had a certain amount of experience in making ships, even if it was to make a model, it would be much easier than other carpentry.

In order to verify his spire-bottomed sailboat, Zhao Yin selected two of the best carpenters in the shipyard, and for them, it was too simple to make a model, and in just one day, the model was presented in front of everyone.

"Master Pony, according to your requirements, the model has been made."

Although they were suspicious of the pony and asked them to make this model, they didn't dare to ask at all, so they could only obediently obey orders.

"Let's go! Go to the water's edge, don't you question this sailboat with a pointed bottom? Then I will show you whether such a boat can be carried on the water. ”

Facts speak louder than words, and no amount of saying is as good as what you have seen.

The shipyard is at the water's edge, so it is not difficult to find a water source, and soon under the leadership of Zhao Yin, everyone came to the water's edge.

Even those craftsmen who had work at hand, after hearing about this, all put down their work and ran over to watch.

Because the sailboat is just a model, you can't go to the sea to experiment, you can only choose a small river to try.

Zhao Yin slowly squatted down and lowered the model of the pointed-bottom sailboat into the river, and after the model only sank slightly, it floated steadily on the water.

"This ...... Really floating? ”

The craftsmen's eyes widened, they didn't expect that such a pointed sailboat could really float on the water, which definitely subverted their cognition.

For so many years, and even the inheritance of the past, all of them are flat-bottomed boats, so in the eyes of these craftsmen, only flat-bottomed boats can float with a large force area, and they didn't expect that such a pointed bottom can also float.

"The villain remembers that the horse said that such a boat can overcome the harsh environment, so it should not be a problem to encounter wind and waves!"

After Liu Cheng finished speaking, he put his hand into the river and kept fiddling, and the waves continued to sweep towards the sailboat.

The model was immediately affected, and the sailboat shook slightly, but the tip of the pointed bottom split the attacking wave directly, although it was also shaking, but the whole was very stable.

"Let's make a flat-bottomed model and let's compare it."

Li Er was surprised by this scene at the moment, and he really didn't think about the fact that the ship would be disturbed by the waves.

"Your Majesty, please wait a while, Wechen will go and get it, some time ago, in order to coax the child, so Wechen deliberately made a toy boat for the child to play with, but it can be used for experiments."

After hearing Li Er's order, the craftsman not far away hurriedly stood up and reported.

I didn't expect that the original casual work would still have the opportunity to face the saint.

"Then what are you still stunned about, why don't you hurry up and get it?"

Wang Dongcheng hurriedly urged.

The craftsman did not dare to slack off, turned around and ran into the distance, and after a while, he ran back with a model in his hand, and put it directly into the river without saying a word.

The two models are basically the same size, and it is best to compare them, and the craftsmen on the side can't wait to see the difference between the two boats under the baptism of the waves, and quickly stir the river.

"The waves are bigger!"

The water surface of the creek was constantly shaking, and both boats were shaking, and it seemed that they could withstand such waves, so Zhao Yin gave the order again.

After the order, the movements of the craftsmen's hands became faster, and the waves in the river gradually became fierce, and the two boats swayed violently in the big waves.

In just a moment's effort, the flat-bottomed boat actually tilted severely, and then slowly sank to the bottom of the river, and the pointed-bottomed sailboat, although it shook violently and constantly swayed with the waves, it always floated smoothly on the water.

"The flat-bottomed boat actually sank ......!"

All the craftsmen were dumbfounded, the punt had always been their faith, but now it was ruthlessly overthrown, how could they easily accept it.

"The sailboat of the horse master is really a god."

After the craftsman Liu Cheng saw this scene, he finally said it convincingly.

This time he was defeated, but his vision has changed drastically, the drawings of the horse master, no, the opinion of the horse master, will be a huge reform for the entire Tang Dynasty ship.

"Where's the sail? Hang it up and experiment again. ”

Recalling the words he had said when this kid first took out the drawings in the palace, Li Er couldn't wait to ask.

If he remembered correctly, the boy had said that with this sail, even in the case of a headwind, he could use the power of the wind to sail, which was really unbelievable to him.

The feasibility of the bottom of the pointed bottom has been confirmed, so there is no need to study this point, if the sail is as magical as he said, then the technology of the Datang ship will take a big step.
