Chapter 947

Li forgets to worry about this busy work, but everyone doesn't know why.

No one knows what this operation means.

Until Li forgot to worry, bent down to pick up the copper coin and threw it to the ground, the people were stunned to find that the two hemispheres had not split, as if they were a complete copper ball.

No matter how Li forgot to worry about kicking and rolling, the copper ball didn't crack.

"Ziyou, what's your trick? Why are the two hemispheres combined?" Cheng Yaojin shouted.

Li Qieyou and others asked questions, nodded to Cheng Yaojin with satisfaction, and explained: "Your Majesty, after all the water in the copper ball was extracted just now, there is neither water nor air in the copper ball. My master calls it 'vacuum', that is, void, that is, space with nothing..."

Before he finished, he had not had time to explain in detail, but he saw several figures and rushed over.

"Li, Li Gong, what you said is true? Now there is a vacuum in the copper ball?"

"Amitabha, the vacuum mentioned by benefactor Li, but the vacuum in the Buddhist scriptures is wonderful?"

What was stimulated by Li forgetful worry's vacuum was the noble monks of Taoism and Buddhism.

The term "vacuum" in later generations refers to that when the air pressure in the container is lower than atmospheric pressure, the part lower than atmospheric pressure is called vacuum.

But in fact, the word vacuum has existed in China since ancient times. It refers to true nothingness, which is the "nothingness" of Taoism. The "emptiness" of Buddhism also borrows this concept.

Buddhism likes to talk about emptiness and Taoism likes to talk about nothingness. In fact, both of them have very similar original meanings.

At the moment, the eminent monks of Buddhism and Taoism have created a "vacuum" in the copper ball in front of them. How can they not be excited?

Li Qieyou was also slightly stunned, but he was too lazy to correct them.

Anyway, regardless of Buddhism or Taoism, apart from the philosophical and spiritual aspects, the "vacuum" in their scriptures refers to nothing.

After getting Li's positive reply, the Buddhist and Taoist monks became more and more excited.

"Duke Li, can you create a wider vacuum for us? Can you let me experience cultivation?"

"Amitabha, benefactor Li, I have the same idea in Buddhism. Please help me. If benefactor Li is willing to help me, Buddhism should do everything to repay the benefactor's kindness."

The words of several gaozhen eminent monks made Li forget to worry dumbfounded.

To practice in a vacuum environment?

This is going crazy!

Later movies described that people suddenly enter a vacuum environment, which will expand and explode due to air pressure.

This is actually incorrect.

After entering the vacuum state, the blood in the human body will boil rapidly and the body surface will expand. After more than ten seconds, it is probably the time when the oxygen absorbed by the lungs is transported to the brain through the circulatory system. People will lose consciousness, shock, and then lose pressure and die of hypoxia.

This is almost a well-known thing in later generations. No one will be mentally disabled enough to want to run to the vacuum environment.

But the Tang people naturally did not understand this. As soon as these eminent monks heard the word "vacuum", they were excited and forgot themselves.

After Li forgot his worries and was stunned, he could only smile bitterly and explain the consequences of people entering the vacuum environment to several eminent monks.

Gao Zhen and eminent monks turned pale when they heard him say this, but they could only temporarily give up the idea of "suicide".

Li forgot to worry and then continued to explain to Li Er and others: "why do the two hemispheres become one? The reason is very simple. After the air in the copper ball is pumped away, the copper ball is tightly pressed by the external atmospheric pressure, like a pair of invisible hands, with great force. Therefore, it is impossible to separate it without enough strength."

After he said that, Li Er and all the officials could not wait to come around and observe the copper ball closely.

"Zhiniang thief, these two hemispheres are really one. If I hadn't carefully checked the two hemispheres before, I'm afraid I would really think there's something in them." Cheng Yaojin pulled the copper ball several times, and there was no sign of separation.

Taichang Qing, Wang Ying, Hou Junji and others all came close and looked at the copper ball over and over.

The two copper hemispheres formed a complete copper ball, which was beyond everyone's expectation.

Without any mechanism, glue and other things, how can the two copper hemispheres be firmly bonded together?

Is it really caused by air pressure, as Li forgets to worry about?

Hou Junji's face inevitably began to turn black. Among the crowd, the faces of Prince Qiao and others also became ugly.

A haze flashed in the hearts of several people.

It doesn't matter to lose some money, but for them, losing face is more important.

Now the facts are in front of everyone. For what Li forgets to worry about, the existence of atmospheric pressure has been believed for some points.

Taichang Qing Wang Ying still stuck her neck and shouted, "even if these two copper balls are pressed by what air pressure, it doesn't mean that we can bear the air with 200 stones at any time?"

Li forgot to worry and looked at Wang Ying like an idiot: "do you have the weight of 200 stones? The prince will know as soon as he tries. You can try whether you can separate the copper ball."

"Hum, I don't have that much strength."

Cheng Yaojin and Yuchi Jingde, several generals, immediately stood up, grabbed a section of the copper ball and pulled it to both sides.

But even if they are brave, they can't shake the copper ball.

All the civil and military officials present came out one after another and began to pull the copper ball. Even Li Er was very excited and tried it himself.

Li forgot to worry and smiled without saying anything. Even Ma Zhou, Yan Liben and others had a smile in their eyes.

The hemispheric experiment is certainly not the first time today.

After he successfully built the piston vacuum pump, Li forgot to worry and did the experiment with his disciples, otherwise he would not dare to do the experiment in front of everyone today.

If something goes wrong, it'll be fun.

Ma Zhou, Yan Liben and other disciples have already learned in detail what atmospheric pressure is from Li forgetful's mouth. They have also personally carried out hemispherical experiments. Naturally, they know how much force it takes to pull the copper ball out of the air.

After everyone tried, Li forgot to worry and ordered Niu Wu to bring the horse he had already prepared.

"Ziyou, what do you mean?" Li Er asked puzzled.

"Your Majesty, the atmosphere has pressure, and its power is amazing, which can not be shaken by human power. Therefore, in order to make your majesty and the princes more intuitively feel the pressure, the minister ordered people to prepare horses, that is, to pull the copper ball with horses to test the power of atmospheric pressure."

Li Er roughly understood the meaning of Li forgetting sorrow and nodded with interest: "good, you can start quickly."

Waiting for the drivers to prepare the horses and fix the rope and the copper ball, Li forgot to worry, turned his eyes, smiled and came up to Li Er. He whispered, "uncle, do you think this horse can pull the copper ball away? If only you had a bet with your nephew?"
