If there is a video recorder, at this moment, the scene that takes place in the Gewu Mansion is destined to be passed down through the ages.

However, now I can only let Yan Liben, who will be a master craftsman, make a cameo appearance as a painter.

"Just now, Du He asked this king a question, and there may be many people who will have the same question."

Li Kuan thought about it and felt that when gravity was mentioned, if buoyancy was not taken out and talked about together, there would be no way to explain why feathers fall slower than heavy objects such as iron balls.

"Why do people think that heavy iron balls hit the ground earlier than light iron balls? This king thinks that in this daily life, everyone sees that the fluttering leaves fall later than the fruit, and the feathers fall slower than ordinary items. ”

After Li Kuan's words were finished, they really resonated with many people.

"Yes, why do the leaves fall later than the fruits?"

"Could it be that only sturdy things land at the same time?"

"It's a little weird."

"Because things fall from the sky, in addition to being affected by gravity, there is also buoyancy." Li Kuan didn't sell it, and directly said the answer, "I estimate that many of you present have heard that there is a hot air balloon in the Chu Palace, and this hot air balloon can float in the air because of the influence of buoyancy. ”

"Lord Wang, according to what you said, is it because the buoyancy of the leaves is greater than that of the fruit, so the rate of decline is slower than that of the fruit?" Li Yan stood at the front of the crowd below and couldn't help but say loudly.

"That's right, the first task assigned by this king to the Gewu Academy is how to determine the gravity and buoyancy of an object, and how to quantify them. Whoever can answer this question first will be rewarded by this king. ”

Li Kuan is not ready to directly take out the calculation formula of gravity and buoyancy, which is not very significant.

The students of Gewu Academy need a process of exploration, and they need to continuously improve their arithmetic, Gewu knowledge, etc., after accumulating a few years, Li Kuan will push a little in the back, maybe there will be surprises.

"Trick up!"

Seeing that Li Kuan was singing a one-man show there today, the eldest grandson snorted coldly and left with his hands behind his back.

And Li Kuan didn't stay in Guanshishan Academy any longer, and after the crowd dissipated a little, he also returned to the other courtyard.

At the same time, the Baiqi Division also reported today's incident to Li Shimin for the first time.

"Did this heavy iron ball and light iron ball really land at the same time?"

Li Shimin listened to the report and felt a little incredible.

"Yes, His Royal Highness the King of Chu personally did several experiments, and each time it landed at the same time, whether it was an iron ball or a wooden block."

"This thing is really ......"

Li Shimin couldn't help but pick up a teacup and inkstone from the table, stood up, and stepped on the table with one step.

Lan He, who was in charge of serving Li Shimin's daily life, was taken aback.

"Lan He, you stick to the ground, see clearly, and after a while, the teacup and inkstone in my hand will not hit the ground at the same time."

Li Shimin glanced around and felt that Lan He was the most suitable for this job.

"Huh?" Lan He was stunned for a moment, "The old slave obeys." ”

When Lan and his limbs were lying on the ground, and his whole chin was about to touch the ground, Li Shimin said "pay attention" and let go of his hands.

"Bang!"

The teacup and inkstone are torn apart.

"Ahh

At the same time, Lan He's right hand was tightly covering his face, and a stream of blood flowed from between his fingers.

Li Zhong saw this scene on the side, and his face couldn't help but tremble a few times, as if it was not Lan He who was hurt by the broken teacup, but himself.

The conscience of heaven and earth, there is finally someone to share the harm of His Royal Highness the King of Chu for himself.

You've got company!

In the future, if you feel bitter, you can also find someone to talk about.

"Your Majesty, the teacup and the inkstone are on the ground at the same time."

Although Lan He's face was scratched, his mind was still very clear, and he knew that what Li Shimin was most concerned about at this moment was definitely not whether he was seriously injured or not, whether he was broken.

"Really landed on the ground at the same time? This inkstone weighs at least five times as much as a teacup, so it stands to reason that it should hit the ground at least a while before the teacup. ”

Li Shimin couldn't help but take another deep breath.

My understanding of the world doesn't seem to be as full as I imagined.

"Li Zhong, that Guanshishan Academy, you have to pay more attention, if there is anything new coming out in the future, I must know it as soon as possible."

Vaguely, Li Shimin had a trace of expectation for Guanshishan Academy.

……

In Guozi Prison, Kong Yingda listened to Lu Xuan talk about what happened in Guanshishan Academy today, and couldn't help but scold.

"Ridiculous! I know how to engage in some strange lewd skills all day long, according to the old man, this Guanshishan Academy is a scourge. ”

As a descendant of the Confucian family, Kong Yingda pays much more attention to the various teaching institutions in Chang'an City than others.

The Mengxue and primary schools in the Chu Palace, as well as the current Guanshishan Academy, basically do not teach scriptures much, even the academy is one of the six colleges in the Guanshishan Academy, Kong Yingda also feels that Li Kuan does not respect the ancestors.

Of the six colleges, only one is for the study of scriptures.

In the entire madrasa school, there is not a single great Confucian who can handle it.

Now, His Royal Highness the King of Chu actually came forward to help the unpopular Gewu Academy platform......

Why have I never heard of Li Kuan's contribution to the promotion of scriptures?

The more Kong Yingda thought about it, the more angry he became.

However, if Li Kuan is here, it is estimated that he will also complain.

Who says I didn't contribute to the promotion of the scriptures?

Isn't it his own credit for the Confucian classics that the Japanese sent to the Tang Dynasty to bring back to those people?

"Master, this King of Chu is deeply loved by His Majesty, as long as he doesn't harm His Majesty, who can do anything to him?"

Lu Xuan couldn't help but sigh, feeling that he always couldn't understand what was going on in Li Kuan's head.

As a disciple of Fan Yang Lu's family, in fact, Lu Xuan knows very well that in addition to some people in the family who have big opinions about Li Kuan, there are also many people who want to cooperate with him.

Even, it was rare to invite an aunt who married Fang Xuanling as his wife, and passed on the idea of Fan Yang Lu's intention to cooperate with the King of Chu.

Unfortunately, there was no response.

According to Lu Xuan's understanding, in fact, Qinghe Cui's family also has similar actions, and even Li Kuan's future mother-in-law can be regarded as being born Cui's, but ......

This guy just doesn't get in at all.

To say that he took the initiative to find trouble with the family, it seems that the same cannot be said.

However, every time he made something, there was always a family that was unlucky.

"Hmph, don't let the teacher catch the handle, otherwise I will definitely impeach Guanshishan Academy for its fallacies and confuse the public."

Although Kong Yingda was angry, there was nothing he could do about Guanshishan Academy for a while.

People don't even participate in the Ming Jing Department and the Jinshi Department at all, even if they want to exert influence in Confucianism, it seems that they can't bring them any great lethality.
