After Shennong took over as the co-lord of the world, he always remembered the teachings of the people of no return, thinking for the people of the flood and famine, and Shennong ruled the world with virtue and righteousness. He acted above board, was impartial, and was loved by all the people of the world. Where he governs, the people are diligent without reward, the people are righteous without punishment, and the people live a rich and happy life.

After humans learned to grow grains, many of the inedible grains were destroyed because they were not well preserved. Shennong also taught everyone to catch young beasts and birds in the mountains, raise them with the food that cannot be eaten, and then slaughter them when the young beasts and birds grow up. In this way, it can be said that it kills two birds with one stone, which not only gives full play to the function of those inexhaustible grains, but also eliminates the danger of the human race going to the mountains to hunt. Slowly, people found that pigs, sheep, dogs, chickens and other six animals are the best to raise, so they are collectively called "six animals".

The emergence of five grains and six animals marks that human civilization has entered a new stage of agricultural development. At this time, there is a surplus of the fruits of human labor.

Since then, people no longer lack food, and there is still a surplus, sometimes the surplus is too much to eat and cannot be stored for a long time, so it has no choice but to throw it away, which is wasteful.

Shennong couldn't, so he had to ask the no-return Taoist for advice, and the no-return man smiled when he heard this: "Why is this difficult, let me ask you, the east family has five grains, the west family has six animals, and each has a surplus, but the east family has five grains but does not eat six animals, and the west family has six animals but does not eat five grains, how can the two sides not only eat one of them?"

Shennong is a natural sage, naturally it is a little bit of a pass, immediately ordered people to establish a street in the city of Chendu, and use it as a city to the people of the world, gather the goods of the world, trade and retreat, each has its own place. In this way, people can exchange their surplus items with each other for what they think is worth and useful, which not only greatly reduces waste, but also uses it in useful places.

At that time, the human race was still wrapped in animal skins, and later Shennong treated hemp as cloth, and promoted it, and since then people have used linen to make clothes, no longer need to wear animal skins, and gradually get out of ignorance!

Although there is Fuxi invented the Se, but the people in addition to production or there is no richer life, Shennong then is to take the tung of the East China Sea, cut it for the piano, knot the silk for the string, three feet six inches and six minutes long, there are five strings, said: Gong, Shang, Jiao, Zheng, Yu. Its sound can be the virtue of heaven and earth, can express the sum of Shennong, can make people entertain, people are called Shennong Qinye!

When the human race baked food with their hands, if not careful, it would often be burned, but also lack of utensils to hold things, Shennong is to make all kinds of utensils that can be contained in the soil, called pottery, since then people can use pottery to hold food, much more convenient.

Although he knew the spring, summer, autumn and winter, but did not know when to plant grain seeds, when was the harvest season, Shennong then observed the changes of the four seasons for several years, alternating between cold and warm, and improved the calendar in the Fuxi era, setting the calendar day, setting the stars, dividing the day and night, setting the sun and the moon, the month is 30 days, and November is the winter solstice. Since then, people have learned when to plant grain and when to harvest, so that production has increased a lot.

Shennong because of the time of the day, the benefits of the land, the beginning of the agricultural work, the righteousness, the cold and the temperature, thought that the period of morning and evening, so the calendar. Shennong manages the tribe, does not expect its retribution, does not covet the wealth of the world, and the world is rich. Wisdom is more valuable than others, and the world respects it. He is virtuous and righteous, the people are diligent without reward, evil and righteous without punishment, rich without resentment, obedient to the people without orders, powerful but not killed, legal and not annoying, and the people are all respected.

Under Shennong's governance, the development of the human race has entered a new era, but new problems have also arisen one after another.

This year, the weather was abnormal, and it didn't rain for a long time. Under the great drought, the harvest of the human race is not good, and there are often cases of people being poisoned by poisoning by eating poisonous substances by mistake. This kind of sentiment made Shennong start to worry. Then, Shennong often had to hear that some old and weak people occasionally encountered headaches and fevers that could not be cured, and some people died like this, and even some middle-aged men and women could not work in such a situation, so they could only lie in bed and wait for improvement, and these phenomena are now more and more, and then there are more and more people who accidentally eat poison or are injured by poisonous insects and poisonous snakes, but the human race is helpless, and can only watch the tribe die.

After thinking about it for a long time, Shennong still couldn't find a solution to this matter, so he had to go to find his teacher and ask for help.

After hearing Shennong's complaint, the Taoist said: "Between heaven and earth, all things are born and restrained by each other, birth, old age, sickness and death, which is the foundation of living souls, even the saints cannot be exempted from the suffering of all beings, and the human race is sick, because it is the cause of the mortal womb of the flesh, however, there is a way to live and die, and the pain can be treated with medicine, but there are countless diseases in the world, and the drugs used are not the same, if you want to get rid of the diseases of the human race, I am afraid it is not easy." ”

"Please teach me, Master!" Shennong quickly knelt down and said when he heard this.

"That's it, you have a heart, and I will help you. The no-return Taoist sighed, knowing that next, this Shennong was afraid that he would suffer for many years, so he took out a copper tripod and a soft whip from his arms, handed it to Shennong and said: "This is the innate spiritual treasure creation tripod, which is born with the vitality of creation, used to refine medicine and medicine, and is the most suitable. ”

"Thank you, Master. Shennong was overjoyed when he heard this, and hurriedly took over the Creation Ding and Chu Whip, and then said goodbye to the Taoist and went to seek medicinal herbs.

Shennong got the guidance of the returnees, and identified all things in the world to seek good medicine, in order to solve the pain of the human race, but there are many kinds of things in the world, although Shennong has a whip given by the returnees, and can distinguish the attributes of each plant clearly, but he knows the specific attributes, but he does not know the quality of these plants, the efficacy, what can cure diseases, what can harm people, what diseases can be cured, and how to solve the problem of being eaten by mistake.

In the end, Shennong made up his mind, he decided to try all things in the world in person, distinguish the good and evil of the herbs, he has a natural crystal belly, can distinguish what herbs are poisonous, what herbs are not poisonous, can also distinguish the efficacy of herbs, and has merit in the body, can resolve toxicity.

Along the way, Shennong didn't know how many kinds of herbs he had tried, among which there were countless poisons, every time the poison entered the abdomen, Shennong was tortured, although relying on his crystal belly and merits, he was able to turn the corner every time, but such a continuous pain made him tortured, and his originally strong body became old, like a centenarian.
