Fang Yizhi, Changsun Chong and others didn't know about these things.

"evil creature!"

When they returned to Chang'an City from Lijiazhuang, they had just entered the house, but they saw the black faces of Aye and others as dark as the bottom of the pot.

It made several people feel a sudden heart.

After thinking about it, I kept staying in Lijiazhuang honestly and did nothing. After confirming that it was not the one I caused, I quickly asked carefully: "Aye, who made you so angry, I'll take revenge on you!"

"Rebellious son!"

Hearing this, Fang Xuanling, Changsun Wuji and others looked even more angry.

But, it cannot be said explicitly.

"Aye?"

Fang Yizhi and Changsun clashed with each other, and they were all confused.

Just so happened that this would follow behind, escorting the servants who were escorting the map all the way, and bringing in the map they drew.

"This is?"

In their respective mansions, Changsun Wuji, Fang Xuanling and others looked at the familiar map that was carried in from outside the door, with surprise in their eyes.

"Aye, this map is a map drawn by the child according to the map drawn by the Master, and specially presented it to Aye!"

Fang Yizhi, Changsun Chong and others hurriedly reported the report.

"Can you draw a map?"

After hearing this, Fang Xuanling, Changsun Wuji and others were stunned, but they had long forgotten the small map that Fang Yizhi and others presented to them a few days ago.

“That’s right!”

Fang Yizhi, Changsun Chong and others said proudly.

Fang Xuanling, Changsun Wuji and others had already stood up with curiosity, walked to the map, and looked over.

The map in front of me is somewhat similar to the map they saw in Liangyi Hall.

Immediately, they remembered something and quickly took out the small map presented by Fang Yizhi and Changsun Chong and others a few days ago to compare it.

The handwriting and lines are as ugly as the lines, and it was really painted by my own rebellious son.

After confirmation, Fang Xuanling, Changsun Wuji and others' faces suddenly soothed, and a smile couldn't help but appear on the corners of their mouths.

Seeing this, Changsun Chong, Fang Yizhi and others didn’t understand what was going on?

They all subconsciously breathed a sigh of relief. Fortunately, they followed Gao Ming and drew a picture, which made their father be kind and filial!

...

The second day.

Fang Xuanling, Changsun Wuji and others had not had time to show off with Li Shimin.

Just after the morning court, Li Shimin hurriedly brought them to Lijiazhuang.

"Xuanba, where is the steel ship?"

As soon as he entered the villa, Li Shimin began to ask with anticipation.

"Your Majesty, please follow me to the back garden!"

After seeing Li Shimin, Li Xuan took Li Shimin and others to the back garden.

Behind him, Fang Xuanling, Changsun Wuji and others were all surprised and suspicious.

Steel vessel?

How could it be so wasteful if you actually use steel to make ships?

Moreover, can ships made of steel really float on the water?

However, thinking that this was the Jin King's House, and His Majesty seemed to know what was going on, Fang Xuanling, Changsun Wuji and others did not ask and followed silently.

Soon, the group came to a pool in the back garden.

Li Shimin, Fang Xuanling and others were directly attracted by the two exquisite boats beside the pool.

Although they are small boats, each one is half a person's length, and its internal style is almost the same as the ships of the Tang Dynasty Navy. The most important thing is that these two small boats are made of steel.

"Your Majesty, Prince, you can check it out. This ship is made of steel and the whole body. The ship next to it is made of wooden boards, and then tightly wrapped in steel!"

Li Xuan introduced on the side.

Hearing this, Li Shimin and Li Xiaogong quickly touched and checked.

Nodded secretly.

"Your Majesty, these two ships were built by the craftsmen in the palace in accordance with the style of the Datang Navy's boat ship. If these two ships can float in the water, it will prove that the giant ship made of steel can also sail on the sea!"

Li Xuan said slowly.

"Your Majesty, what Your Highness, King of Jin, said so!"

On the side, Li Xiaogong also looked expectant.

"It is the first time I have seen a ship made of steel. Xuanba will try it!" Li Shimin nodded slowly.

After hearing this, Li Xuan didn't say much, and picked up the ship wrapped in steel and slowly placed it in the water.

And the ship just sank a little and then stayed steadily on the water.

Seeing this, Li Shimin, Li Xiaogong and others couldn't help but look overjoyed.

Then, Li Xuan picked up the ship made of steel again and slowly placed it on the water.

Similarly, this ship, which is all made of steel, floated on the water after sinking a piece.

Suddenly, Li Shimin, Li Xiaogong and others couldn't help but widen their eyes and looked disbelief.

"How is this possible?"

"It can really float!"

Li Shimin couldn't help it and hurried to the pool, fiddled with the ship, which was all made of steel for a while, and then let out a long sigh.

"Your Majesty, these iron blocks are the weight of the ship's cargo and crew. You can see if the ship can still float with cargo and people!"

As he said that, Li Xuan was on the shore again, picked up a few large pieces of steel and placed it on the steel ship.

What once again surprised Li Shimin, Changsun Wuji and others was that the steel ship just shook and did not sink much, and his face was even more shocking.

"Xuanba, putting steel in the water will definitely sink into the water. Why can ships made of steel float?"

Li Shimin asked curiously.

"Your Majesty, this matter involves density, weight and buoyancy. I explained it differently for a while, but Your Majesty can borrow the human body to describe it. If people breathe in their stomachs, they can swim and float in the water.

Similarly, it is also empty inside the steel ship, but it is just an open space, and it can still float on the water!"

Li Xuan explained slowly.

However, Li Shimin, Fang Xuanling and others still couldn't understand.

They didn't continue to ask. Anyway, Xuanba wouldn't explain in detail to them, or if they explained, they wouldn't understand.

Instead, he directly pulled the steel ship, carried it on the shore, and began to look over and over again.

In less than a while, the few people were sweating profusely.

Although the inside of the steel ship is hollow, such a large ship still has about one hundred kilograms.

"Your Majesty, since steel ships can float on the water, can you build a giant steel ship for me?"

On the side, Li Xuan glared patiently for a while, and after Li Shimin went over to be curious, he began to ask.

"The giant steel ship?"

Hearing this, Fang Xuanling, Changsun Wuji and others subconsciously asked questions.

"Your Majesty promised that if you can prove that the steel ship can float on the water, you will build two giant steel ships for me with steel!" Li Xuan said indifferently.

"Two giant ships made of steel?"

Upon hearing this, Fang Xuanling, Changsun Wuji and others subconsciously took a cold breath and then hurriedly looked at Li Shimin.

Those are two giant steel ships!

When did Your Majesty lose his family?

"Your Majesty, it takes at least tens of thousands of kilograms of steel to build a giant steel ship. I'm afraid there will be some shortcomings in steel this year!" Fang Xuanling said slowly.

"What, the Duke of Wei wants to give advice and let Your Majesty be untrustworthy?"

Li Xuan was furious and said coldly.

"Your Majesty forgives your crimes, Your Highness, the King of Jin, is a little confused for a while, and he has no such thoughts!"

Fang Xuanling was shocked and quickly saluted and apologized with fear on his face.
