After Shennong succeeded to the throne of the emperor, he taught the human race to dig wells on the ground to get water, or to draw water from the river to irrigate the crops, which changed the situation that the human race relied on the sky to harvest, and also taught the human race to use soil to make pottery, so that the human race had basic daily necessities such as clay pots. With the efforts of Shennong, the agriculture of the human race was initially established, and sometimes the tribesmen still had a surplus of grain for a year, so Shennong set up a bazaar to let people exchange some surplus grain, forming a primitive transaction.

The human race does not have a mature understanding system of plants now, and people often eat plants that should not be eaten and are poisoned, Shennong saw that he was very unbearable, he decided to go all over the wilderness, vowed to taste all the plants in the world, and recorded all their special surnames, so that people know what they can eat and what they can't eat.

In a few years, Shennong's footprints have traveled all over the world, and he has indeed found a lot of edible food for the human race, but he has been poisoned a lot of times, sometimes he can be poisoned more than ten times in a day, Shennong used his strong physique and familiarity with drugs to survive again and again, and complex toxins actually formed a subtle cycle in Shennong's body.

This said Shennong was ready to taste the herbs he had just discovered, this herb was green and slender, it was a little beautiful from the appearance, Shennong did not know the special surname of this herb, he took out some of his emergency herbs, and prepared to eat them immediately if the herbs were poisonous, who knew that after eating, this seemingly beautiful grass was highly poisonous, and the poisonous surnames in his body were destroyed under the impact of this poison, and the delicate situation was destroyed at once, this new poison began to spread like the old poison, Shennong was ready to reach out to get the herbs he prepared, but the poisonous surname of this grass began to spread, and his intestines seemed to be cut off, fell to the ground in an instant, Shennong knew that his life was short, but it was a pity that he had not written all the medicinal materials into a book, and even the half of the grass in his hand that killed him was not recorded.

At this time, not far from Shennong, Styx was watching with Liu'er, and Liu'er beside him was shocked when he saw Shennong fall to the ground, they had been together for five years, and Liu'er wanted to save Shennong as soon as he moved, but Styx smiled slightly, stopped him and said, "Shennong was not saved by you." After hearing this, Liu'er could only be anxious in place, and at this time, a Taoist came down from the sky and fell in front of the two.

"The younger generation has many treasures, and I have seen the seniors. The person who came was Duobao, the eldest disciple under the throne of Tongtian, and Styx was not surprised by all this, "It seems that Tongtian Daoist friends have high expectations for you! After Duobao thanked the River Styx, he walked towards Shennong, and Liu'er seemed to understand: "It turns out that the ancestor has long known that someone is on it, no wonder he doesn't let the younger generation make a move." Styx shook his head, "You haven't seen it yet." Even if Duobao is not there, I can't let you save Shennong, last time I asked you to help Shennong find Jiusui Valley, it can be said that in the past, if I let you help Shennong again, then what I did would be a bit foul. Styx's words made Liu'er a little confused, foul?

When Shennong's consciousness began to blur, he saw a Taoist man walking towards him and feeding him a pill, and after a while, the poison in his body was completely resolved, and he felt that his body was better than before, Shennong got up and bowed to Duobao: "Thank you seniors for saving my life, I don't know where my predecessors are cultivating, he said I must come to the door to thank you." Shennong is now the body of the human emperor, and Duobao dared to worship him, so he quickly lifted him up before he bowed, and said: "I am the eldest disciple of the Tongtian Sect, Duobao Daoren. ”

Shennong exclaimed: "It turns out that the predecessor is actually a saint's disciple. Duobao didn't show any proud expression, but said: "Although you are inspired to taste the herbs all over the world, but after all, you are a mortal after all, take the poisonous herbs in your hands today, you will be poisoned by the same herbs as it sooner or later, don't you regret it?" Shennong was firm, "No matter how long my life can come, as long as I am not dead, I will continue to do it, so that the human race will suffer a little less." ”

Duobao will not let Shennong continue to taste like this, but only listen to Duobao said: "You are always a mortal, and you can't avoid danger every time." Poor Dao can take you as an apprentice and help you achieve the Immortal Dao, so that you will have more time to identify the Hundred Herbs, what do you think?" Shennong was overjoyed when he heard this, and immediately agreed, because Duobao was right, only if he achieved the Immortal Dao, then he could not be afraid of those poisons, so that he could collect more herbs. Duobao taught the Shangqing Dao Dharma to Shennong, and at the same time took out a whip and handed it to Shennong: "This is the ochre whip refined for the teacher for you, this thing can identify most of the herbs in the wilderness, the ochre whip will become darker when it hits the poisonous herbs, the more poisonous the plant, then its eyes will be deeper, I hope it can help you speed up the pace, but the ochre whip can't identify poisonous animals, so you still have to be careful." ”

With the Shangqing Dao method passed down by Duobao, Shennong finally cultivated the immortal road, after ten years with the help of the ochre whip, all the herbs tasted all, for each herb of the medicine surname all recorded, wrote a book "Shennong Hundred Herbs", once this book was born, the sky was rolling thunder in an instant, Shennong did not know why, Duobao's figure appeared in the air, and said: "Shennong, the things of heaven and earth are full, you wrote this book to exhaust the things of heaven and earth, so this book can not be complete." Duobao said, Shennong's hand of the "Shennong Hundred Herbs" is divided into two, half of which remains in Shennong's hands, and the other side escapes into the air, this book is Shennong exhausted all his efforts to write, just born was separated, the heart is also very declined, the other side of the hand is recorded are common herbs and poisons, although it is also very beneficial to the human race, but the other half of Shennong's book is the most essence, which records the rare spiritual objects and herbs in heaven and earth.

Although only half of the "Shennong Hundred Herbs Sutra" has been preserved, this half is also a treasure for the human race, and under Shennong's teaching, the human race began to have the art of medicinal stones, and will no longer eat the dead as often as before. But Shennong found that when someone was sick, he didn't have time to decoct the medicine at all, and if he accidentally ate something highly poisonous, he would die before the medicine was boiled, just like when he ate the broken intestine grass. At this time, Shennong remembered that when Duobao fed him the pill, Shennong knew that it was made of immortal medicine by Duobao, if ordinary herbs could be refined into pills, then could it also achieve the effect of preserving medicinal power?
