Datang romantic little landlord

After a little thought, Li Wangyou had an idea.

"I'm afraid you don't know what's in the air, right? Why don't I tell you about the air today?"

Li Wangyou's words made everyone startled again.

Air?

Gao Zhen, a few Taoists, suddenly became excited: "Li... Li Gong, you are talking about empty energy? This, I am afraid that this matter should not be announced to the public, right? This is the secret of my Taoism!"

These few old Taoist priests used to call each other Huxian Li Wangyou, but now they all changed their tune and called him Li Gong.

I don't blame them for being so excited, it's just that they misunderstood what Li Wangyou meant.

The air in Li Wangyou's mouth was different from the empty Qi they thought.

Since ancient times, China's understanding of air has been vague and contradictory.

The word air is derived from Taoism, and it is also written as "empty energy".

But Taoism's emptiness refers to the vitality, clearness, and breath of a person, not the air mentioned by later generations.

"Laozi", "Liezi", "Zhuangzi", "Guanzi", "Heguanzi", "Xunzi", "Huainanzi", "Huangdi Neijing", these Taoist works or works related to Taoism, all describe Qi It is very mysterious, and it is considered to be innate vitality.

The scattered form of "Tao" is Qi, and the gathered form of Qi is "Taishang Laojun"... Qi is a kind of metaphysical mysterious energy, which is the cognition of Qi in Taoist philosophy.

As for the air, because it cannot be seen or touched, the ancients could hardly describe it.

Therefore, among the five elements in China, there are only gold, wood, water, fire, and earth, and there is no existence of the most important "qi".

The ancients only knew that people need to breathe air, and there will be wind in the untouchable air... that's all.

These veteran Taoists thought that what Li Wangyou was going to talk about was the qi of Taoism.

As for the existence of qi, Li Wangyou doesn't know either, maybe it's just like the internal energy in later novels, it's hard to prove.At least the science of later generations has not yet explored the mystery of the real vitality of heaven and earth.

Li Wangyou was stunned by the words of several Taoist Gaozhen, and then realized that they misunderstood what he meant.

"Hehe, everyone Gao Zhen, the air I'm talking about is still a little different from the Qi of Taoism. What I want to talk about is the air we breathe all the time."

Gao Zhen and the others looked at each other, not quite understanding what Li Wangyou meant, so they could only listen to him continue talking.

"Your Majesty, gentlemen, the air I want to talk about refers to the invisible, intangible, but ubiquitous air that I can't live without for a moment. The word qi is the breath of smell."

In the hall, including Li Er, everyone fell silent, listening to Li Wangyou's words.

Even that old fellow Wang Ying, even though he was unhappy with Li Wangyou, was listening very seriously at the moment.

"You may not know that the air around us seems to be empty, but it is not."

"Air is mainly composed of oxygen and nitrogen, and oxygen is the source of our life support..."

Li Wangyou poured out all the knowledge he could remember about the air, picking out the content that everyone could understand, like a popular science lecture.

These unheard of knowledge, but everyone was dumbfounded.

Even many officials couldn't help stretching out their hands and scratching randomly in the air a few times, as if they wanted to test whether they could grab oxygen from the air.

Different from Li Wangyou's previous description of the composition of sunlight, this air is even more mysterious to everyone.

At least everyone can see the sunshine and feel its temperature, but the air is really incomprehensible to Tang people.

After Li Wangyou finished his popular science on air, everyone fell silent, bowing their heads and thinking in secret, digesting the knowledge in it.

Especially those Taoist Gaozhen and Buddhist eminent monks were even more pensive.

Whether it is Taoism or Buddhism, there are methods on how to meditate, adjust breath, and practice, and the key point is breathing.

But they never knew that there are so many substances in the air.

So what is it that they meditate, exhale and breathe?

On the other hand, the old fellow Taichangqing Wang Ying burst out laughing: "Li Ziyou, who can prove your words? Since the air is invisible and intangible, how do we know, what you said is right , is the knowledge imparted by Taoist ancestors, not your own random fabrications?"

Li Wangyou hadn't answered Wang Ying's words, but saw the Taoist Gao Zhen frowned, and retorted: "Your Majesty be careful, although what Li Gong said, Pindao and others don't understand it, but Pindao does not understand it. Clearly, this is definitely not fabricated by Mr. Li."

Tai Changqing and Wang Ying's nose was about to crooked from anger.

He felt that he was kind enough to speak out for these Taoists Gao Zhen, and he questioned Li Wangyou, why are these stupid people so ignorant of good and evil?

But before he could refute, Li Wangyou said with a smile: "Your Majesty, I don't understand. Even though the air is invisible and intangible, I still have a way to prove what I just said..."

943 atmospheres

Li Wangyou didn't have the ability to separate oxygen and nitrogen from the air.But it is not difficult to prove that the air is not empty.

Combustion test can prove the existence of oxygen.

The famous physics experiment, the Magdeburg hemisphere experiment, is more than enough to prove that the air is not empty, and clearly and intuitively prove the existence of atmospheric pressure.

"It's not difficult at all to prove what I just said. Your majesty, gentlemen, and master once told me that in fact, each of us is under the pressure of air at any time. Well, it is roughly equivalent to..."

Li Wangyou calculated silently in his heart, and gave an answer: "It's about the weight of two hundred stones."

One standard atmospheric pressure is equivalent to ten tons per cubic meter.One ton is one thousand kilograms, and two thousand catties is roughly equivalent to twenty stones of the Tang Dynasty.

Anyone who has studied physics in junior high school understands that because the atmospheric pressure in the human body is in balance with the external atmospheric pressure, the human body will not be crushed by the atmospheric pressure, and the human body cannot feel the existence of the atmospheric pressure.

Atmospheric pressure is common sense in later generations, but people in Tang Dynasty did not understand it.

Li Wangyou's words, in the ears of everyone, were pure nonsense.

Wang Ying jumped out again as if she had caught Li Wangyou's sore foot.

"Haha, the old man thought, Li Ziyou, you could come up with some great truths, but I didn't expect that you would be talking nonsense like this. If each of us is pressed with the weight of two hundred stones of air, we will wait Couldn't he have been crushed to death long ago?"

As he spoke, he ignored his old arms and legs, and jumped up and down the hall twice.

"Could it be that Li Ziyou thinks that the old man is also a god? With a weight of two hundred shi on his back, he can still run and jump?"

Wang Ying's words immediately caused a burst of laughter in the Tai Chi Hall.

Everyone didn't know the truth of what Li Wangyou said before, so they didn't dare to refute it.But if it is said that everyone has a pressure of two hundred stones on their bodies, this is too nonsense, and none of the officials will believe it.

Several officials of the aristocratic family immediately laughed and echoed: "Could it be that Mr. Li has hallucinated with Taoist Xiu Xianxiu? Can such ridiculous remarks be said?"

"Hey, it turns out that XX is so powerful, he can carry a weight of two hundred stones on his back, and he can walk like flying. Tsk tsk, it seems that XX is about to become a fairy."

"Yes, it turns out that we are all in the immortal class. If Mr. Li had not informed us, we would not have known it, hahahaha."
