"This is easy to do, the imperial court can leave some, and the rest is still like private sales, it is estimated that the people will compete to buy it!"

Zhao Yin said with a smile.

Even if the navy has a large number of ships, it is impossible to exceed the needs of the people of the Tang Dynasty, you know, the merchants who come and go from the south to the north take the waterway much faster than the dry road!

Especially after he passed on the sail technology, the demand for boats has greatly increased, and the safety and speed have also improved a lot, and they are loved by the majority of people!

Although sailboats are more practical, they take a lot of time to build, and at the same time, the first ones produced will not be for the masses, so the renovated flat-bottomed boats are very popular!

This also completely solves the waste of flat-bottomed boats, and at the same time, it also gets a lot of start-up capital for Datang!

"Yes, there really is no better way!"

Li Er nodded, without the slightest hint of disappointment.

Zhao Yin's suggestion has saved a lot of money for Datang, otherwise with their original idea, the emergence of sailboats, these flat-bottomed boats will be completely eliminated, or directly destroyed and thrown away.

"Judging from the current market, the imperial court can still make a fortune by selling these ships, and the son-in-law will congratulate his father-in-law in advance."

Zhao Yin bowed his hand to Li Er with a smile on his face, he couldn't believe that this old money fan would not be moved.

Datang's business is now in a state of rapid development, so the demand for ships is huge, and in the past, flat-bottomed boats could only use the monsoon to come and go once a year.

But now the advent of sails, which allows ships to sail normally under all conditions, has undoubtedly lit up the eyes of those merchants.

Therefore, this not only did not make the price of second-hand ships drop, but even made the price of second-hand ships increase exponentially.

Even some shipyards have been waiting for orders for several years, and Zhao Yin has no intention of interfering in the shipbuilding business.

Because it is impossible to keep the technical secret, whether it is the sail or the design of the pointed sailboat, it will not be long before it will flow to the society.

For the entire Datang, this is also a major reform on the waterway.

"Tomorrow the steamship will be launched for a trial trial, and I will definitely be there to see it in person, you kid, don't let me down."

Li Er's face smiled, and his old face was like a blooming chrysanthemum at this time.

"Yes!"

……

Early in the morning of the second day, Zhao Yin, who was working hard, heard Wang De's shout from outside the door, so he reluctantly got off the bed and walked towards the palace with a stomach full of resentment.

"Virtuous son-in-law, you're finally here, the big guys are waiting for you!"

As soon as he entered the Taiji Palace, Sun Wuji, the old yin goods chief, greeted him with a smile on his face.

Zhao Yin was stunned for a moment, then he glanced inside, and found that except for Li Er's accident, all the other princes were actually present, and they all looked at him with a happy face, and that look couldn't help but make him shudder a little.

But soon he figured it out, Li Er was going to show off to these old guys!

An hour later, everyone rushed to the shipyard.

And Wang Dongcheng and a group of shipbuilders have been waiting here for a long time.

"This big guy is a steamer, right?"

Looking at the steel fortress in front of him, Li Er's eyes suddenly lit up, once the experiment was successful, then who would be able to stop him?

"My good man, such a thick iron plate, I'm afraid that bows and arrows and strong crossbows will not hurt a bit!"

Cheng Yanjin reached out and knocked on it curiously, and then he was amazed.

And the other ministers were also dumbfounded, and it was the first time they had seen such a steel fortress, just like Grandma Liu entering the Grand View Garden, full of unknowns.

"Are you kid sure this big guy can float?"

Li Er was quite satisfied with the construction of the steamship, but now he was worried about whether such a bulky thing could really float on the sea?

"Can this steamer float or not?"

Too lazy to popularize the knowledge of buoyancy for these three guns, Zhao Yin said very calmly.

"Where's the angle and the lever?"

After looking around for a week, Dai Xuan asked questions.

In the navy of the Tang Dynasty, the general way of fighting was hand-to-hand combat, so these two things were indispensable at all!

"There's no need to use those things!"

Zhao Yin glanced at him and explained lazily.

Such a steel fortress does not need those burdens at all!

"Why?"

Dai Xuan suddenly wondered, without these things, how to compete with the enemy?

"There's already artillery on it, do you think those things are still useful?"

There are already long-range artillery in the ship, and the enemy can't get close at all, so why bother.

"What? You say this is an artillery piece on it? ”

After hearing Zhao Yin's explanation, everyone finally understood why this kid didn't install these things.

"Nonsense, if you can't install artillery, how dare this thing say that this thing can dominate the sea?"

Zhao Yin had a proud look on his face.

With the slow development of technology, these mechanized things can only get better and better.

"So what are you waiting for? Let's get in the water and try it! ”

After hearing Zhao Yin's explanation, the light in Li Er's eyes was so bright that he even couldn't wait to get up, and hurriedly opened his mouth to urge.

With an order, the steamer was pushed into the water by a group of craftsmen, splashing all over the sky, and no one wiped the splash on his cheeks with his hands, and all of them stared at the water with wide eyes, for fear of missing this wonderful scene.

Contrary to everyone's expectations, the steel fortress did not sink, but floated smoothly on the water.

"It's really floating!"

Everyone looked at the steamer with their mouths wide open and looked at the steamer in shock, followed by exclamations of joy.

When the steam engine is installed on the ship, it is to transform the power of the steam engine into the power of the ship.

Of course, there are still sails on this kind of ship, but they are not used under normal circumstances, and the real function of the sails is to keep sailing when the steam engine fails, so as not to throw the ship into the sea.

"The drill begins!"

With Zhao Yin's order, a group of navies quickly ran towards the steamship.

In order to allow the navy to quickly operate the steamship, Zhao Yin also specially called them to the general to supervise the operation of the steam engine.

In addition, he also drew a group of people in the artillery team to instruct these navies on the use of artillery.

Soon a hundred soldiers ran to the beach, and then rowed quickly in small boats in the direction of the steamer.

Li Er and the other ministers stood on the shore, staring at the steamship without blinking.
