Li forgot to worry about this, but it attracted all the officials in the hall to applaud.

If Li forget worry is really a disciple of the Taoist ancestors in the world, they can also listen to some immortal family's "secrets that are not preached", which is naturally a good thing.

Wang Ying's face was a little ugly, but she could only nod silently to agree.

As for those Taoist and Buddhist monks, they were all silent at the moment. Even the eyes of several Gao Zhen looking at Li forgetful are somewhat strange.

Obviously, today's scene was beyond their expectation.

No one expected that complaining to Li Er would evolve into today's situation.

There is speculation in everyone's hearts whether Li forgetful worry is the disciple of the Taoist ancestor in the world.

Now taichangqing Wang Ying jumps out to fight against Li forgetful worry. Naturally, these old foxes are silent and watch the change.

Only Li Er has a tangled face.

He has already believed what Li forgot to worry about for seven or eight points.

At this time, his nephew said that he would continue to tell the people that the knowledge taught by the Taoist ancestor was unknown to the world, which made Li Er dissatisfied.

Stingy Li Er has subconsciously regarded these knowledge as their Li's wealth.

Daozu is the ancestor of Li Shimin, and Li QIAOYOU is his nephew. These knowledge unknown to the world naturally belongs to their Li family. How can outsiders know it easily?

For a moment, Li Er wanted to stop the matter, and Li forgot to worry about it.

But immediately Li Er took back the words he was about to export.

Since Li forgets to worry about setting up a course called "Encyclopedia" in the Academy, the content of the professor is the knowledge taught by the Taoist ancestors.

If it was ordered by the Taoist father, even if he was an emperor, he could not stop it.

So it's better to ask Li forget you privately after the event.

Li Er didn't object. The officials in the hall looked forward to it. Li forgot his worries and coughed a little, pretending to meditate and paced back and forth.

He also thought in his heart, what knowledge to shake up the group of "woodlouse", so that they believe their own words.

After a little thought, Li forgot his worries and had an idea.

"I'm afraid you don't know what's in the air? What if I tell you about the air today?"

Li forgot to worry about this, but it stunned everyone again.

air

Several Taoist Gao Zhen suddenly became excited: "Li... Li Gong, you're talking about empty energy? I'm afraid it's not appropriate to publicize it to the public? It's the secret of our Taoism!"

Before, these old Taoists called Hu County Li forget worry one by one, but now they all changed their names and called them Duke Li.

I don't blame them for being so excited, but they misunderstood Li forgetful.

The air in Li forgot to worry's mouth was different from the empty energy they thought.

Since ancient times, the understanding of air has been very vague and contradictory.

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

However, the empty energy of Taoism refers to people's vitality, clear Qi and breath, not the air described by later generations.

Lao Tzu, Liezi, Zhuangzi, Guanzi, sheguanzi, Xunzi, Huainanzi, Huangdi Neijing, these Taoist works or works related to Taoism, all have mysterious descriptions of Qi and think it is innate vitality.

The scattered form of "Tao" is energy, and the concentrated form of energy is "supreme Lao Jun"... Energy is a metaphysical mysterious energy, which is the cognition of energy in Taoist philosophy.

As for air, it was hard for the ancients to describe because it could not be seen or touched.

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

The ancients only knew that people need to breathe air, and there will be wind in the air that can't be touched... That's all.

These old Taoists thought that what Li forgot to worry about was the energy of Taoism.

As for the existence of Qi, Li Qiyou doesn't know. Maybe it's just like the internal skill in later novels, which is difficult to prove. At least later generations of science have not yet explored the mystery of the real vitality of heaven and earth.

Li was stunned by the words of several Taoist Gao Zhen, and then reacted that they had misunderstood their meaning.

"Hehe, you Gao Zhen, there is still a little difference between the air I said and the Taoist energy. What I want to talk about is the air we breathe at any time."

Gao Zhen looked at each other. They didn't quite understand Li forgetful, so they could only listen to him continue.

"Your majesty and gentlemen, the air I want to talk about refers to the air that can't be seen, touched, but everywhere. I can't leave it for a moment. This word is the smell."

In the hall, including Li Er, they all quieted down and listened to Li forgetful words.

Even the old man Wang Ying, although unhappy with Li forgetting his worries, listened very carefully at the moment.

"You may not know that there seems to be nothing in the air beside us, but it is not."

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

Li Qieyou poured out all the knowledge about air that he could remember and what people could understand, just like a popular science lecture.

These unheard of knowledge, but all the people listen to silly eyes.

Even many officials could not help but reach out and grab a few times in the air. It seemed that they wanted to try whether they could catch oxygen from the air.

Different from the composition of sunshine described by Li forgetful worry before, this air is a mysterious existence for everyone.

At least people can see the sunshine and feel its temperature, but the air is really hard to understand for the people of Tang Dynasty.

After Li forgot to worry about the popular science of air, everyone was silent, bowed his head and thought secretly, digesting the knowledge.

The Taoist Gao Zhen and the Buddhist monks were even more thoughtful.

Both Taoists and Buddhists have dharmas on how to meditate, regulate breath and practice, and the key point is breathing.

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

So what is it that they meditate and breathe?

It's too often that Qing Wang Ying, an old fellow, puffed and laughed: "Li Ziyou, who can prove that? Since the air is invisible and untouchable, how can we know that what you said is right. It's the knowledge taught by the Taoist ancestors, not made up by yourself?"

Wang Ying did not answer this, but Li forgot to worry. He saw the Taoist Gao Zhen frown and retorted, "Duke Wang is careful. Although I don't understand what Duke Li said, I know that Duke Li didn't make it up."

Too often, Wang Ying's nose is almost crooked.

He felt that he was kind enough to help these Taoist Gao Zhen speak and questioned Li forgetful. Why are these ox noses so ignorant of good and bad?

But before he could retort, Li forgot to worry and said with a smile: "prince, I don't understand. Even if the air can't be seen or touched, I have a way to prove what I just said..."
