In addition to the unobtrusive ones like "Zhan Chapter" and "Asking for Rain", the twenty articles of "Shennong" must also be had, since they are in the name of Shennong's inheritance, these are essential. Pen & Fun & Pavilion www.biquge.info

But most of the pages of this book have great benefits for agricultural production, especially for a county in Jiangdong, Wei Zheng came to visit the sages of the peasant school, and the biggest purpose of inviting them out of the mountain was to ask them to govern Jiangdong scientifically.

The topography of the south is very different from that of the north, and the south is full of smoke and rain, and what makes people talk about it is miasma.

The reason why the Central Plains is a fertile place in the world is because of the main arteries of mountains and rivers headed by the Yellow River, which inject rotten water and a series of precipitated toxic and disease-causing organic compounds, as well as their salinity into the sea along the circulating river water.

Regarding the miasma in the south, which made the people of the Central Plains smell and change, there is no second person in the whole world except Wei Zheng who knows how the so-called miasma is generated, and the common people and even the saints don't know the reason, they only think that the air in the land of the South Barbarians is highly poisonous.

In fact, the formation of miasma in the south is largely due to the problem of poor drainage, the south is not as smooth as the Central Plains, and the sparsely populated and lack of human "transportation" is also a major reason.

South Vietnam is a land of mountains, dense jungles, ravines and ponds, which often retain rainwater, and such depressions are found almost everywhere in South Vietnam.

Slopes on the surface, fallen trees, and collapsed mountains can create countless depressions of varying sizes.

In addition, the south is not more rainy than the north, the south has more rain, the temperature is high, and the carrion of wild animals has become a "bacterial soup" rich in organic matter or a "breeding room" for mosquitoes.

In addition, after the death of mountain wild animals and plants, especially poisonous animals and plants, the corpses are exposed to various miasma-causing poisonous gases produced after the decay of the wilderness, the excretion of wild animals and their biochemical reactions, and the stagnant water liquids and gases that are difficult to evaporate in the potholes are mixed and "fermented" in the hot and humid closed environment of the dense forest and mountainous areas, and the bacteria and viruses are finally integrated into the humid air.

This is where the miasma comes from.

Wei Zheng knew this, but apart from him, no one else knew that the ignorance of his thoughts caused people in the world to be unable to figure out the real reason for the miasma in the south, even if he was a saint.

For the unknown, people will only assume that the sky in the land of the Southern Barbarians is inherently containing deadly miasma toxins, which are said to be the poison of Baiyue and are not suitable for the people of the Central Plains to live.

Sometimes there were large swarms of mosquitoes in the southern sky, which looked like clouds from a distance, so it was assumed that there was something wrong with the air in the southern barbarians. In particular, the people of the Central Plains, who were born and raised in the local area, are "not accustomed to the water and soil", and even more talked about the color change, if it were not for the continuous war in the Central Plains, no one would be willing to move south.

The solution to the miasma has been written into the twenty articles of "Shennong" by Wei Zheng, and it is not much of a problem to fool Xu Xing with the name of the sage Shennong.

What is a saint, a saint is a person who can learn without a teacher, a person who can educate the people is called a saint, and the word saint represents a kind of authority.

The lineage of the saints is naturally convinced.

“…… In addition to the miasma, it lies in the development of water conservancy, through the mountains and rivers Heze ......" Xu Xing focused on reading, at this moment he had already forgotten about entertaining guests, and before he knew it, an hour had passed, Wei Zheng was not in a hurry, he sat on the ground leisurely, silent, and saw that the more Xu Xing showed concentration like this, the more confident he was that he could invite him out of the mountain.

At this moment, Xu Xing is reading the "Mountains and Rivers Chapter" in the 20 articles of "Shennong", in which there are a lot of pen and ink to introduce the mountains and rivers of the world, which focuses on the unique miasma in the south, the formation of miasma, and the harm of miasma to people.

"I see, I see." Xu Xing couldn't help but say to himself in amazement: "The miasma of the Southern Barbarian Wilderness is not out of nowhere, the sage Shennong clan has already seen through everything!" ”

Xu Xing continued to read in detail, since the sage knew the cause of the miasma, he must also know how to get rid of the miasma, and he was convinced of the inheritance of the Shennong clan.

Sure enough, the further he read, the more he looked at his countenance, which gradually changed from expectation to surprise, the sage really had a plan to get rid of the miasma, and couldn't help but repeat for a while: "...... Running water does not rot, I see...... I see......"

The sage said that the first thing to remove the miasma is to pass through the mountains and rivers, so that the rotten water and stagnant water deposited in the potholes in the mountains and rivers and dense forests are discharged into the river and then into the East China Sea through the river water, and there is no source of miasma, and the miasma will naturally dissipate.

After reading the "Mountains and Rivers Chapter", Xu Xing read the next one, which is the "People's Livelihood Chapter".

Wei Zheng glanced at it and continued to wait patiently, the "People's Livelihood Chapter" is a sage teaching the people how to rely on the mountains to eat the mountains, rely on the water to draft water, and develop the benefits of the mountains and rivers.

In the "People's Livelihood Chapter", the sage Shennong clearly said that Xu Xing understood that the land in the world became barren because of the destruction of "repulsion".

The so-called "rejection of halogen" is actually saline-alkali, such land is not conducive to crop cultivation at all, and the "people's livelihood chapter" explains that the formation of "rejection of halogen" is caused by impurities, mountains and rivers that cannot be drained, which is easy to understand, because after the water is boiled, there will be deposited foreign matter, this phenomenon has long been discovered by the ancients.

The article said that if you want to turn barren soil into fertile land, you must remove the "rejection of brine" in the land, and the "people's livelihood chapter" also gives a solution to the problem, that is, through the "rootless water" year after year, the mountains and rivers are constantly washed, and the water conservancy is built to integrate the "repellency" in the land into the water and inject it into the rivers and then into the East China Sea.

"Water without roots" is distilled water, of course Wei Zheng will not directly write a word of distilled water in the twenty articles of "Shennong", and it is a truth to use "repulsion of brine" to describe saline-alkali land, which is easy to understand in ancient times. And the water without change is rainwater, and rainwater is the water that has been "distilled" by nature, and there are basically no minerals.

When Xu Xing saw this, he gradually understood, because the sage's article had made it very clear that if you want to turn barren land into fertile land, the key is to drain water, and let the water flow and not be deposited for a long time into stagnant water and rotten water. The sage also said that the reason why there are countless fertile fields in the Central Plains is precisely because there are countless rivers and rivers, and the people cultivate year after year, and the rootless water falls from the sky year after year, which repeatedly reduces the "rejection" of the land, and the land is gradually fertile.

If you think about it carefully, this is indeed the case, the Chinese tribe has lived and cultivated the land of the Central Plains for thousands of years, so all sides are barbaric and barbarous, but the Central Plains has countless fertile land.

"A-!"

Xu Xing finally finished reading the twenty chapters of "Shennong", especially after reading the "People's Livelihood Chapter" and "Mountains and Rivers Chapter", he couldn't help but applaud. When he looked at Wei Zheng, he still couldn't help but exclaim: "It is worthy of the study of a saint, Xu never thought that the miasma that made the people of the Central Plains smell change color was such a reason, let alone that the miasma did not come out of nothing, and the miasma was not impossible to eliminate." If the lineage of the saints had not been lost......"

"Mr. Xu has inherited the inheritance of the sage, and Xu Zi is a great sage in the world for the peasant family, doesn't he want to let the sage's learning be carried forward and widely beneficial to all the people in the world?" Wei Zheng laughed softly.

Xu Xing, who was indulged in it, couldn't help but look at Wei Zheng in a daze, the latter looked at him with a smile, and Xu Xing calmed down before thinking of something more important.

Legalists and celebrities came to visit, and even gave the sage Shennong's inheritance, which ...... Xu Xing arched his hand and said: "Your Excellency came to visit in person and gave such a great gift of sacred learning, Xu Xing was grateful, and he didn't know how to repay it." ”

Wei Zheng returned the salute with a smile: "Shennong's learning, entering the peasant family is the only way to return the things to the original owner." ”

Xu Xing said again: "There is a confusion that the old man does not notice, what is the purpose of your ...... trip?"

Wei Zheng slowly got up under the surprised gaze of the other party, took a few steps and stood in front of Xu Xing, and when he saw him dressing up, he closed his hands and saluted: "I want to invite Mr. out of the mountain...... Help me! ”

As soon as these words came out, the two Chen Xiang brothers' pupils shrank and their faces were shocked.

The other party is actually visiting Xian? So what is his identity...... After thinking about it, a certain identity was about to come out in the minds of the two.

Xu Xing immediately got up and stared at Wei Zheng in front of him, and bowed his hand: "Your Excellency is not Li Zi, a famous scholar of the Legalist family?" That's ......"

Meng Ben immediately replied on behalf of Wei Zheng: "My lord is the lord of the country today, what Mr. said is yes or no, Li Zi is the pseudonym of my lord, Mr. understand?" ”
