Not long after, Li Su came to the court.

"Son-in-law, see father."

Li Shimin couldn't help but reprimand: "King Shu, in the impeachment of your Zhonghua Academy by the imperial history, the teaching materials used are absurd and wrong. ”

"I wonder who compiled this textbook?"

Li Shimin still wants to try his best to protect Li Su.

Therefore, when he was questioning, he gave Li Su a good step.

As long as Li Su pushes out a substitute for the dead ghost to come out.

When the time comes, it will be good to punish this substitute ghost directly.

As for the Zhonghua Academy, if it can be guaranteed, it will be guaranteed, but if it can't be kept, it will be temporarily closed for a while.

Anyway, in this scene now, it would be good to be able to keep Li Su.

When the eldest grandson Wuji heard the emperor's words, he couldn't help but sneer.

No one can protect the King of Shu today.

Even if he doesn't die, let him peel off a layer of skin.

Then, I heard Li Su, the king of Shu, say: "Father Qi, this textbook was compiled by Erchen himself. ”

"Erchen carefully considered the words, and asked himself that there was nothing absurd, I don't know which imperial historian impeached Erchen or what?"

Hearing Li Su's words, Li Shimin couldn't help frowning.

O my stupid son!

I've helped you build the steps, why don't you know how to go down the steps?

Now, I'm afraid it's not going to end well!

And Yushi Fan Tong, after hearing Li Su's words, couldn't help but have a look of pride on his face.

Fan Tong couldn't help but ask: "His Royal Highness the King of Shu, it is this imperial history that impeached His Highness. ”

"Your Highness wants to ask, in the natural science textbooks, there is one that is on the calm surface of the water, and the pressure of the water is only related to the depth?"

Li Su nodded and said, "Yes, that's right." The pressure of the water is only related to the depth of the water. ”

Fan Tong suddenly accused in a loud voice: "It's just nonsense! How ridiculous! ”

"It's an attempt that a three-year-old knows! How much does the pressure of water have to do with the depth of the water? It also has a lot to do with the area of the water surface. ”

"Even if it is at the same depth, how can it be the same in the well water, the lake water, and the seawater?"

Li Su smiled slightly, and then asked: "How dare you ask Fan Yushi, a fish can dive to the bottom of the well in the well water." ”

"Is it possible that when you enter a lake, the water pressure at the same depth becomes so high that the fish can't dive?"

When Li Su raised this question, everyone in the court couldn't help but show a look of thought on their faces.

Before Li Su raised this question, they had never thought about it.

They just instinctively felt that the water pressure must not be related to the depth of the water alone, which is definitely not right.

But as for why it's wrong, they simply don't know.

And now that the King of Shu said this, they suddenly felt that it seemed that what the King of Shu said also made sense.

And Fan Tong said in a loud voice: "What nonsense! You're messing around! ”

"Fish live in the water, how can it feel the pressure of the water!"

It's terrible to be uneducated!

Fish are also afraid of water pressure, and in the deep sea of the sea, there are few fish.

However, Li Su was not prepared to give him such a profound theory.

Because he doesn't understand at all, and even if he does, he will mess around.

Li Su decided to give him a simple little experiment.

Thinking of this, Li Yu couldn't help but say: "Fan Yushi, according to what you said, a closed wooden barrel, together with a hollow bamboo pole several zhang high, fill the bamboo pole with water, and the pressure on the wooden barrel will not be very great, right?" ”

Fan Tong said proudly: "This is natural, this is a theory that even a three-year-old child knows, why should His Highness ask more?" ”

Li Su smiled and said: "If you can frackard the wooden barrel by adding water to the bamboo pole, will it be able to prove that the water pressure is only related to the depth of the water?" ”

Fan Tong said disdainfully: "If it can be fractured, it will naturally be able to prove it." ”

"But how can fracking be possible? It's simply not possible! So, there are no ifs! ”

Li Yu smiled slightly and said, "Okay, since Fan Yushi is so confident, why don't we do an experiment?" ”

Hearing Li Su's words, Fan Tong couldn't help but ask: "Okay, since you firmly believe that you are right, why don't you do an experiment!" ”

"By the way, if it turns out that His Highness is wrong, so what? Is Your Highness about to confess your sins? ”

Li Su said: "This is natural, but if it turns out that I am right, what about Fan Yushi?" ”

Fan Tong sneered: "If His Highness is right, which official is willing to resign and not do it!" ”

"Okay, then it's a deal!"

Next, Li Su began to instruct people to prepare the utensils for the experiment.

Li Shimin's face was full of worry.

I was secretly annoyed that Li Su didn't know how to change.

Su'er used to be very smart, why did she suddenly become stupid today?

This is an attempt that even children know!

Isn't it humiliating to have to do some experiments?

If the experiment fails, it will really not end well.

However, the words came here in a hurry.

At this time, the little eunuch had already prepared all the equipment used in the experiment.

Li Shimin had no way to stop it.

Before the experiment, Li Su called Fan Tong and said to him:

"Fan Yushi, these experimental utensils, please check them first, whether they are firm."

"Don't make excuses after the experiment fails."

After hearing Li Su's words, Fan Tong really checked it carefully.

Including several other imperial historians, they all came to help with some inspection.

This wooden barrel is the wooden barrel used in the Imperial Palace.

The quality is absolutely high and it is very strong.

After the inspection, Fan Tong said that there was nothing wrong with the experimental equipment.

Next, Li ordered the barrel to be filled with water.

Then the top is covered with a lid for sealing reinforcement.

In the lid of the wooden barrel, a hole of the same size as a bamboo pole is taken, and then the bamboo pole is placed and reinforced.

And the location where the barrel is prevented is in the highest palace of Daming Palace.

A guard came to the top floor of the palace, carried a bucket of water, and began to add water to the bamboo tube.

All around, Tang Emperor Li Shimin and a cadre of ministers were all watching around, waiting to see the jokes of the King of Shu.

This kind of experiment, even if it is done a hundred times, the King of Shu will lose a hundred times.

Above the palace, the guards have added a second scoop of water, and the wooden barrels below are still unharmed......

Hey?

Do I make up?

Why is this barrel still leaking?

Is it not fixed?

However, in the next moment, the barrel cracked bigger and bigger, and it had already cracked several times.

The water in the barrel suddenly gushed out.

The wooden barrel was really crushed by the water in the bamboo pole!

In other words, water pressure is really only related to height, or depth.

Even if it's just a bamboo pole, as long as it's high enough, it can create terrifying water pressure.

This experiment completely subverted their cognition.

What they thought was right was not true.

What they thought was wrong is actually right.
