Qingxu rode the auspicious clouds and brought Shennong to Chendi, and then asked Shennong to hand over the affairs of the tribe to his subordinates. He then asked Shennong to practice Shangqing with him during the day, and at night, he taught Shennong some pharmacological knowledge and the way of governing the country. He counted in a hurry. Ten years passed in the blink of an eye. On this day, Qingxu handed the divine whip that had been trained by the Japanese before to Shennong and said: "This is a treasure made by my master with the Yin of Yimu. It can identify thousands of plants and trees. You can know it if you have whipped it with this whip." This plant is poisonous and non-poisonous, but it is convenient for you to identify the poisonous and non-poisonous plants, but it can only distinguish the poisonous and non-poisonous plants; it cannot distinguish the intensity of the toxicity. If you want to know the toxicity, you have to test it yourself, but you have to remember that there were countless foreign substances in ancient times. Even if you are a teacher, you don't know what you are doing, and you don't dare try your way. Although you are very fast, you still don't want to try something that looks strange." Shennong said, "If you can identify all the poisonous things in the world,. And if I can find a cure so that my people can no longer suffer, I will have no regrets even if I die." Qingxu was stunned when he heard this and thought, "He deserves to be one of the three emperors. This kind of heart is already far away from the four major Mahayana Buddhists in later generations. "Bodhisattva." Then he said, "Since you have the intention to become a teacher, I don't want to stop you, but I still want to be careful and leave as a teacher." After saying that, he walked out of the wooden house and rode on the auspicious clouds back to Jiuhua Mountain. . Qingxu returned to Jiuhua Mountain and began to refine the fragments he had picked up when Gonggong crashed into Buzhou Mountain. He heard Qingxu say: "It took thousands of years to finally refine all the fragments into one. Now we are waiting for Shennong's certification." After gaining the position of Emperor of the Earth, you can make it by adding all the merits you have into it. Although the size is not as big as the Heaven-turning Seal, but with my guidance, the merits obtained by Nuwa Empress in creating human beings can be divided into the merits obtained by assisting Empress Nuwa in mending the sky. In addition to the merits obtained by professors Fuxi and Shennong, with these four merits added to it, I think it should not be weaker than his Heaven-turning Seal. After a while, I will go to the Youxiong Tribe to find Xuanyuan Ji. She should be born soon. Wait for Xuanyuan to attain the title of Human Emperor. After taking the throne, I will preach in the prehistoric human race in the name of the Master of the Three Emperors."
Not to mention that Qingxu was refining magic weapons in Jiuhua Mountain. When Shennong saw his teacher driving away in the clouds, he summoned the tribal leaders and officials to ask about the affairs of the human race in the past few decades. I heard that there were no major events in the human race. It was just that the old and weak tribesmen occasionally suffered from headaches and fevers. It was still unimaginable when it happened. Some tribesmen died like this. Even some middle-aged boys and girls were unable to work in such a situation. They could only lie in bed and wait for improvement. Moreover, these phenomena are becoming more and more common now, and they are caused by accidentally ingesting poisons. There are more and more tribesmen injured by poisonous insects and snakes. Although there is a record of Fuxi going out and bringing back poisons, now more and more tribesmen need land, and more and more tribesmen need to go to the mountains and forests to burn mountains for forests. Encountered many plants and trees I had never seen before. Fuxi was startled when he heard this, "Although something like this happened to me before I started practicing with my teacher, no one died. Why is there a clan member dead now? I should have asked the teacher if I had known that." In the blink of an eye, Shennong thought again: "I can't always rely on the teacher, because I can't always rely on the teacher. It's time to find a way to solve this problem by yourself, and it's time to go out and identify the poisonous nature of the plants, otherwise more and more people will be poisoned, and things to treat bites from poisonous insects and snakes must be found as soon as possible." Shen Nong didn't know that everything would be beneficial. There is a disadvantage. Although grains allow the tribesmen to get more food, the people who eat grains are not as healthy as those who eat meat. Therefore, some diseases that were basically harmless to the tribesmen in the past can now be fatal.
When Shennong heard these things, he couldn't sit still. After arranging the affairs of the tribe, he went out and walked deep into the mountains. Along the way, whenever he saw any vegetation that he had never seen before, he would whip it with the ocher whip made by Qingxu. Check whether they are poisonous or not and record them. At night, he drank the poisonous weeds to test their toxicity. Shen Nong slowly discovered that various poisons have five-element attributes, and some powerful poisons were mixed with several kinds. The power of the five elements is so toxic that Shen Nong observes its cold, warm, flat, and hot properties, distinguishes its monarch, minister, and assistant, and uses it slowly to detoxify and cure diseases. One day, Shennong found a vine-like plant with small yellow flowers in a crack in the rocks. He whipped it with ocher and found that it contained highly poisonous substances. He ate the flowers and stems into his stomach. Soon after, he felt a terrible pain in his stomach, as if his intestines were broken. He hurriedly After working hard to dissolve the poison, Shen Nong stood up and wiped the sweat from his head and said: "Fortunately, I have the Taoist law passed down by my teacher to protect me; otherwise, I would have died here. I must write down this herb and tell the people to avoid it." If you eat this grass, you will die. If you eat it, your stomach will hurt, as if your intestines are broken. After decades of research, it has been found that licorice can treat coughs, rhubarb can treat constipation, and yellow lotus can reduce swelling, etc. .
After decades of debate and tasting, Shennong finally tasted almost all the plants and trees and wrote a book "Shen Nong's Materia Medica". "Shen Nong's Materia Medica" explains the three-class classification of drugs and their performance and significance. The position and function of medicines in the compatibility of prescriptions, the combination of yin and yang, the harmony of seven emotions, the four qi (cold, hot and warm) and the five flavors (spicy, sweet, sour, bitter and salty), the collection and preparation of toxic and non-toxic drugs, the decoction method of drugs, the relationship between drugs and disease syndromes, etc. When this book was finished, merit came from the sky and fell on Shennong. At the same time, a mass of merit fell on Qingxu in Mount Jiuhua. Shennong returned to Chendi and began to teach the tribesmen the art of medicine. Shennong also found that some diseases made people sick quickly. By the time the medicine was cooked, the patient was already dying and the medicine had no effect even after taking it. So Shen Nong wondered if he could find a way to preserve all the essence of the medicine and take it when the patient first became ill. Then the patient could take it early and save his life. Shen Nong thought for a long time but couldn't find a way. Suddenly, one day Shennong remembered that when he was poisoned by a snake, his teacher gave him a pill of elixir that cured him. He couldn't help but think: "The elixir is made by the immortals by removing the dregs from the jelly grass and fairy fruit. So people should also be able to use it." Herbs were made into elixirs, but Teacher 1 didn't teach me how to make elixirs. Teacher En's dojo was in Jiuhua Mountain, so I went to Jiuhua Mountain to find the teacher for advice. "
Thinking of this, Shennong flew to Jiuhua Mountain on a cloud. It took Shennong several months to fly to Jiuhua Mountain. At this time, Qingxu was at Dachitian Taishang Laojun's place. It turned out that Qingxu calculated that Shennong would come to him to ask for help refining elixirs. However, I was not proficient in alchemy. I was embarrassed for a while and then I remembered that the alchemy skills of my uncle, Taishang Laojun, were the best in the world, so I rushed to Dachitian to ask Taishang Laojun for alchemy skills. As soon as he arrived at Dachitian, he saw Master Xuandu standing at the gate of Bajing Palace, waiting for Qingxu to arrive, and he hurriedly stepped forward and said, "Senior brother! The teacher has ordered me to wait here for a long time." Qingxu also knows that saints have different supernatural powers, so he's just afraid the master uncle will know the purpose of his coming when he leaves. Qingxu followed Master Xuandu into the Bajing Palace and paid homage to the old man. Then he sat aside and waited without saying a word. When I saw Qingxu sitting down, I said, "I know your reason for coming. I've prepared the alchemy for you, and I've also refined the alchemy. You can take it with you." After saying that, he handed over a book of alchemy and an alchemist. He handed the small tripod to Qingxu, Qingxu thanked him and said, "Thank you so much, uncle." I said, "My master, Shen Nong, is my disciple." After that, he closed his eyes and went to meditate. Upon seeing this, Qingxu bowed to Master Xuandu and left the Bajing Palace to wait for the outsiders under the leadership of Master Xuandu. After leaving Xuandu Cave, Qingxu said to Master Xuandu: "Junior brother, you don't have to send me off. I've already thought about it." After getting together with my junior brother, we are both the head disciples, but we have no time to spare. I must find some time to talk to my junior brother." After that, he left in the clouds. Master Xuandu watched Qingxu drive away in the clouds, then turned around and entered the Eight Views Palace of Xuandu Cave.
