"Water is closely related to agricultural production, and it is not an exaggeration to say that farming is vital to life."

"In the south, every three inches of rainfall decreases food production by 10 percent. In the north, where there is a lack of rainfall, the three inches of rainfall are even more critical, which directly determines how the people's harvest will be this year and whether it will be unveiled. ”

Li Jinglong and Zhu Gaoxu nodded approvingly.

The absence of precipitation will lead to drought, and drought will lead to locust plagues, and locust plagues will be everywhere, and a few more national fortunes will be a basic pill.

"In fact, the monsoon and precipitation, when it comes to this, are basically over."

Jiang Xinghuo talked for a long time, and his mouth was a little dry.

He paused before saying, "It stands to reason that the next step is to talk about how to use chemistry. Turning decay into magic, to mass-produce items that can increase the yield of crops per acre, and how to use effective methods to use arable land to produce more food in a limited time. ”

"In this way, there will be a way to fight the Xiaoice Age, which will last for hundreds of years and will intensify."

Jiang Xinghuo's expression was slightly in a trance.

He remembered a previous account of the drought at the end of the Ming Dynasty.

In the summer and autumn of the first year of Chongzhen, there was a great drought in northern Shaanxi, and there were fathers abandoning their sons, husbands and wives, digging grass roots to feed themselves, and quarrying white stones to satisfy hunger. In August and September, the people compete to pick the fluffy grass in the mountains and eat, its grains of bran skin, its taste is bitter and astringent, and the food can only be extended to immortal...... At the end of the year and the bark of the trees is exhausted, they dig up the rocks in the mountains and eat them...... Some of the people were unwilling to die by eating stones, and they began to gather together to be thieves, and the first and second people who had a little savings were robbed, and there was nothing left to loot, and there was no prohibition on it.

Jiang Xinghuo himself has been a hungry person, and he knows how little resistance the people have in the face of natural and man-made disasters under the self-sufficient small-scale peasant economy, and how many human tragedies will occur.

Because, whether it was the method of increasing agricultural production that he talked about before, or the method of increasing agricultural production proposed for the Xiaoice River period now, Jiang Xinghuo did not have the purpose of seeking any substantial or honorary benefits.

Asking oneself is nothing more than empathy, not speaking out about the uneasy conscience.

Perhaps for onlookers, the thousands of miles of red land caused by the drought are just a topic of conversation after dinner.

And for Jiang Xinghuo, no.

But before that, out of the professional habits and ethics of the lecturer, Mr. Jiang, who had never had the bad habit of "hiding a hand", decided to talk about a small point that he had not talked about, instead of passing it over.

That is.

What exactly is water?

Jiang Xinghuo asked: "On an additional note, I just said that the wind is formed due to different air pressures, so have you ever thought about how rainfall is formed?" ”

This sounds incredibly simple, childish question.

directly silenced the two big men.

How is rainfall formed?

I've never thought about it.

Zhu Gaoxu was silent for a few more breaths, and asked tentatively, "The dragon king's pee?" ”

Jiang Xinghuo: "."

Li Jinglong: "."

It is not enough to expect these two students to realize on their own, Jiang Xinghuo cleared his throat and said.

"Rainfall refers to a weather phenomenon in which water vapor condenses in the air of the sky and descends to the surface of the land in different ways."

"As we said before, temperature is directly related to rainfall, and the higher the temperature and the more rainfall, because in the air in the sky, the higher the temperature, the more water vapor can be contained in the clouds, and this water vapor, in the beginning, you can understand it as cloud droplets."

"In the early stage, the cloud droplets mainly rely on continuously absorbing the water vapor around the cloud body to make themselves stronger, and if the water vapor energy source in the cloud is continuously supplied and replenished, the surface of the cloud droplets is often in a full state. It's like the feeling that the grain of the fruit is ripe and about to burst. ”

"Then, the process of turning clouds into rain will continue, so that the cloud droplets will continue to increase, and when the cloud droplets in the clouds increase to a certain extent, due to the increasing size and weight of the large cloud droplets, they will not only catch up with the slower small cloud droplets in the process of descending, but also swallow up more small cloud droplets and make themselves stronger, and when the big cloud droplets grow bigger and bigger, and finally the air in the sky can no longer support it, it will fall straight from the clouds to the ground, becoming our common rain."

Li Jinglong couldn't help but say: "The legend says that the dragon swallows the clouds and turns into rain, which is what it means. ”

Zhu Gaoxu couldn't help but bow his head, as if to say, this is the same as the dragon king peeing.

Looking at these two students who were deeply poisoned by feudal superstition, Jiang Xinghuo's face tended to darken a little, but he continued to speak.

"The rainfall I just talked about is part of the 'water cycle', which is the fundamental principle of the operation of the world."

Hearing this, Zhu Gaochi and Xia Yuanji next door didn't react yet, but Zhang Tianshi was in good spirits!

In Zhang Tianshi's mind, he was frantically deducing the logic.

Jiang Xinghuo mentioned "the fundamental principle of the operation of the world".

In Daomen, what is the "fundamental principle of the operation of the world"?

That's the Way!

And what is the Tao?

The Tao is very Taoist, and it is not easy to describe it specifically.

So in the concept of Taoism, is there anything that can be used to make people understand what "Tao" is?

Yes!

Lao Tzu said it very clearly in the Tao Te Ching.

The eighth chapter of the Tao Te Ching says: The good is like water, the water is good for all things without fighting, and the evil of everyone is better than the Tao.

Water is the closest thing to the "Tao".

Jiang Xinghuo said that "the fundamental principle of the operation of the world" is the "water cycle".

That's right!

Everything is on the right track!

In other words, the essence of Feng Shui is the embodiment of the Tao!

And what Jiang Xinghuo is talking about right now is the closest thing to the "Tao", water!

You only need to understand what water is all about, and you can "be more than the Tao"!

"What a fairy! Sure enough, it's a real immortal! ”

"Hahahaha, Dao Ye, I actually had the honor to listen to the true immortal preaching!"

"It's still the water closest to the Tao!"

Zhang Tianshi's eyes had become bloodshot, and his expression was extremely focused, waiting for Jiang Xinghuo's lecture.

He could barely hold his breath.

Although Zhu Gaochi and Xia Yuanji didn't know what Zhang Tianshi had discovered, they saw him so excited that they lost his temper, and they were immediately brought into that atmosphere.

The three of them all stared, waiting for Jiang Xinghuo to teach further.

"The water cycle refers to the continuous and repeated movement of various forms of water in the world through water evaporation, water vapor transport, condensation and landing, infiltration, runoff and other links under the action of sunlight, tides and other factors."

Jiang Xinghuo's voice fell.

Infiltration, runoff?

Zhang Tianshi, who was next door, almost blurted out: "The reason why Jiang Hai can be the king of a hundred valleys is because of his goodness, so he can be the king of a hundred valleys!" What Jiang Xianren said is the real meaning of this sentence in the Tao Te Ching! ”

"This is the secret of the Tao Te Ching!"

"If there is no Jiang Immortal, the word will be broken."

"The world has read the Tao Te Ching for a thousand years in vain!!"

Zhang Tianshi's expression became extremely shocked.

And Jiang Xinghuo's lecture, oh no, for Zhang Tianshi's preaching, is still continuing.

Jiang Xinghuo said slowly: "The water cycle is a cyclical process that successfully connects different parts of the world, so that the water in it is in a state of constant renewal in different cycles, thus maintaining the dynamic balance of water volume. ”

"Water is never static, but constantly moving and shifting in space. The water cycle is not only a complex process, but also an important natural process. It combines various water bodies in the world into a continuous and unified water cycle, and closely links water with rocks, air, and animals in the process of circulation, forming a unity of interconnection and constraints. ”

"At the same time, changing, circulating water further affects the world's material migration, topography and energy transformation."

"For example, the surface water continues to erode, transport, and accumulate surface materials, forming a unique flowing water landform; For example, river runoff continuously transports sediment and salt to the sea, affecting the offshore environment; Another example is the heat absorption, heat release and heat transfer of water in the process of water change, which alleviates the contradiction of imbalance of heat budget in different regions. ”

"Just as wind is formed by the flow of high pressure to low pressure, water is constantly flowing, and in the process, it helps the growth of livestock, people, plants and trees in the world."

The secret room next door.

Zhu Gaochi could see with the naked eye that Zhang Tianshi's expression became extremely weird.

Zhang Tianshi kept muttering a sentence.

"The good is like water, the water is good for all things without fighting, and it is evil for everyone, so it is more than the Tao."

"Good is like water, and water is good for all things."

It is the water that flows incessantly and transforms in this world in various forms that nourishes the growth of all things and silently helps all things.

And "Tao" also exists in various forms, constantly transforming, silently influencing the world?

Good is like water.

Water is good for all things.

The meaning of what Daozu said, in essence, is the "water cycle" that Jiang Xianren talked about!

Figured this out.

Zhang Tianshi was struck by lightning.

Even if it is like ascending to the immortal, a huge amount of pleasure.

The terrifying pleasure of comprehending the "Dao" seemed to make Zhang Tianshi feel that he had no regrets when he died now!

The so-called "Death can be done at night", it turned out that Zhang Tianshi didn't understand, but now he understands what it feels like, that's it! That's it!

"Water Cycle!"

"Everything is born in water!"

"The true ultimate secret of the Tao Te Ching!"

"The meaning of the avenue left by Dao Ancestor, his old man!"

"Daoye, I'm done!"

"Master Dao, I'm done!!"

"Hahahahaha!!"

In the secret room, Zhang Yuchu raised his hands high, revealing his thick black arms covered with sweat under his feather robe.

The sound of horrific laughter echoed in the silenced chamber.

Looking at the familiar scene in the Great Heavenly Realm Temple.

Zhu Gaochi subconsciously shrank the back of his neck, which was full of flesh.

"This is, another crazy one?"
