"Shennong's Materia Medica", as the earliest work of traditional Chinese medicine, is rumored to have originated from Shennong's family, passed down by word of mouth from generation to generation, and was assembled into a book in the Eastern Han Dynasty. Since the Qin and Han dynasties, many medical scientists have collected, summarized and sorted out the experience of pharmacology at that time, which is the first systematic summary of traditional Chinese medicine and the source of the development of pharmacological theory of traditional Chinese medicine.

One of the descriptions of a plant is bitter, cold, and poisonous. The main cough is against the qi, breaks the accumulation, eats, cold and heat, moisture, sores, rat fistula erosion, Gu poison, kills birds and beasts. Raw Valley. "Zhongshan Sutra" cloud, the mountain has grass, its shape is like the old and hairy, blue and white fruit, the service is not dying, can be abdominal disease. "Famous Doctor" said, born in Qin Pavilion and served high. In February and August, the roots are dried in the shade, and they are not used permanently. This is the wolf poison flower.

Between the vast desert and the grassland, clumps of gray-green grass stand proudly in the dust and gravel of the sky, and there are red bones like match heads on the tips of the grass, which is called wolf poison flower. In the harsh wind, the wolf poison flower tenaciously shimmered with dazzling luster in the afterglow of the setting sun. Some say it is more poisonous than a wolf, and it brings fear and the threat of death.

The roots, stems and leaves of the wolf poison flower contain great poison, which can be made into a medicine for external application to eliminate accumulation and clear blood. It can also be used as a pesticide to control borers and aphids. But humans and animals must not eat it. The wolf poison flower has a large root system, strong water absorption ability, and can adapt to arid and cold climates, and it is difficult for the surrounding herbaceous plants to fight against it. The more developed its root system, the more toxic it becomes.

On the plateau, herders gave it such a name because of its poisonous juice. The wolf poison flower has a large root system, strong water absorption ability, can adapt to arid and cold climates, and has strong vitality, which is difficult for surrounding herbaceous plants to fight with. The most important reason for the flood of wolf venom on the plateau is that people overgraze and there are fewer other species, so the wolf venom naturally takes advantage of the situation.

Chun Yuyi knows this thing, because it travels all over the mountains and rivers, if it is placed in an ordinary medical officer, let alone recognize, there are few people who have heard this name. Liu Hong also held such a heart, and wanted to use the wolf poison flower god to kill Liu Ci unknowingly, and then Xu Lai and Liu Wucai instructed people to blame Liu Shuang for Liu Ci's death. In this way, Liu Shuang can be cleaned up and Liu Guang can smoothly take over the throne of Hengshan.

The people sent by Su Ren didn't know what it was, and they didn't even know the names of the medicinal materials, so they took out some of each medicinal material. Thanks to Su Ren, he heard about it from a friend who lived in Inner Mongolia and saw the real thing. After rummaging through a pile of medicinal herbs for a long time, I determined that the one-inch-long plant root was what I was looking for.

Han Qing hesitated for a long time, but still accepted the reality. First of all, he has no other way, if Liu Ci is still sober, maybe he can still listen to him. Now he's a fart, and if he speaks loudly, he'll be killed in an instant, or the kind of guy who doesn't know it. Therefore, he could only choose to believe in Su Ren, hoping that Su Ren would really handle these things as he said.

wanted to kowtow to Su Ren again, but was stopped by Su Ren in advance: "I said you, you have to kowtow at every turn, are you tired?" Does it mean that your knees don't hurt when you kneel on the ground? ”

Han Qing didn't speak, but the brute cow said: "How can it not hurt, it's very uncomfortable!" ”

"It's still a bull, look at you one by one, okay, go back to sleep, it's going to exhaust people to death this day!" Su Ren smiled and yawned heavily.

Liu Shuang couldn't sleep, and Chun Yuyi suddenly came to visit, thinking that he had recommended himself to come to the door to diagnose Liu Ci. Liu Shuang even made up excuses for prevarication, but what Chun Yuyi said was something else. After listening to it, Liu Shuang could stuff an egg in his mouth. Su Ren said so many inexplicable words that day, and Liu Shuang realized that Su Ren was reminding him. repeatedly promised Chun Yuyi that he would never let a tragedy happen, so he sent the old man away.

sat down, the more Liu Shuang thought about it, the more surprised he became, and immediately ordered someone to invite the Minister of State Xi Ci.

Sitting quietly in his study in a daze, his mind was a little messy. Su Ren guessed right, Liu Shuang really didn't have the courage to kill his father, although he also wanted to inherit the throne of King Hengshan as soon as possible, and he didn't treat it in time after Liu Ci fell ill, but let him watch his father being poisoned to death, and ignore it, he Liu Shuang couldn't do it. It's also a father and son, his father was murdered, and the schadenfreate of being a son is a beast.

Xi Ci came quickly, and when he stepped into Liu Shuang's study, he frowned: "Shizi, why don't you light the lamp?" ”

Liu Shuang came back to his senses and took a deep breath: "Sit!" ”

"What's wrong with Shizi?"

"Someone is going to murder my father!"

Xi Ci gasped, and suddenly remembered Su Ren's words that day: "What does the prince mean, Xu Lai and they want to harm the king?" ”

"It's not Xu Lai, it's Liu Hong, or the king of Huainan."

"How is this possible? Could it be that there are assassins in the envoys of Huainan? ”

Liu Shuang laughed: "It's too low-level to send assassins, look at what this is." Liu Shuang handed the wolf poison root that Chun Yuyi brought to Xi Ci.

With the help of moonlight and starlight, Xi Ci looked at it for a long time and shook his head: "It seems to be a medicinal herb, forgive the old minister for being stupid, I don't know what this thing is." ”

"The name of this thing is wolf venom, it is a plant on the plateau, its roots, stems, leaves, and fruits are very poisonous, if it is eaten by a good person, it may be able to relieve cough and remove phlegm, if it is eaten by the patient, there is no more than five days out of ten."

Xi Ci was startled, and the wolf poison flower root in his hand fell to the ground.

Liu Shuang continued: "The prime minister doesn't need to be afraid, although this thing is poisonous, it is effective only when eaten, and there is also a name, called wolf poison flower, the herdsmen on the plateau think that this thing is more terrible than the wolf." ”

"Where did this thing come from, and why is the prince sure that it is from the Huainan Mission?"

"Mr. Chunyu, the divine doctor, came here just now, and he brought this wolf poison flower, saying that he picked it up outside the post house in the east of the city, and he felt strange, so he came to tell me."

Xi Ci's brows furrowed into a Sichuan character: "I picked it up outside the Chengdong Post House, and it can't prove that it is something from the Huainan Mission." ”

Liu Shuang looked up at Xi Ci: "The minister really thinks that Mr. Chun Yu picked it up?" I guess that Su Ren asked Mr. Chunyu to say this, it should be that Su Ren sent someone to the Chengdong Post Station and found it from the things brought by the Huainan Mission, and asked Mr. Chunyu to send it in order to hide people's eyes. ”

Looking at the plant root in his hand again, Xi Ci's head was running rapidly. From Su Ren's words to the current situation, Xi Ci has continued to analyze and imagine. The two of them sat quietly, and the room was so dark that only a palm-sized area could be seen. Sitting opposite each other, you can't see the expressions of the people on the other side.

After a long time, Xi Ci coughed lightly: "Shizi, what are you going to do?" ”

Liu Shuang was silent. Xi Ci continued: "Since there is Mr. Chun Yu as a witness, few people recognize this thing, so it is better to ...... it."

"That's my father!"

Xi Ci immediately shut up and swallowed back the second half of the sentence. Liu Shuang sighed lightly: "I have also thought about it, but it must be my father, if I see him being murdered, I am afraid that this life will be difficult, and now as soon as I close my eyes, I will be the shadow of my father." ”

"Since this is the case, then we have to find a way to involve those two sluts, the old minister thinks that this matter must have something to do with those two sluts, as long as we make efforts to investigate, we will definitely be able to find out."

"Tomorrow is the day of the Huainan mission, less than three hours before dawn, no matter how many people are sent, there will be no result."

Xi Ci said: "That's not necessarily, as long as the king believes it." Xi Ci moved to Liu Shuang's side, leaned on Liu Shuang's ear and began to mutter. There were just the two of them in the house, and Xi Ci's voice was so soft that even if someone hid outside the window, he couldn't hear it.

For a long time, Liu Shuang nodded: "Okay, just do what the minister said!" ”

Since Liu Ci, the king of Hengshan, fell ill, the entire Hengshan country was nervous, especially the palace and Lu'an City, and the level of vigilance had been raised by a notch. Every day, Zhang Guangchang lives on the tower of the city, his clothes are not untied, and his weapons are not left in his hands, so as to prevent any accidents. He is the general of Hengshan Kingdom, and he is also loyal to Liu Ci, and at this dangerous moment, Zhang Guangchang has a great responsibility on his shoulders.

After patrolling around the city, he returned to the temporary rest house on the city tower, and Zhang Guangchang was lying on the couch with his sword and clothes. He was thinking about what else Lu'an City hadn't noticed, and where there was a lack of defense. Suddenly, it seemed that the palace needed to be strengthened, especially around the sleeping palace of King Hengshan. Now that the king is sick, he must not let the villains take advantage of it.

"Report, general, the minister of the country asks to see you!"

Zhang Guangchang got up with a grunt: "Prime Minister? What is he here for? ”

The herald said: "The villain doesn't know, the minister said that there is an important matter to discuss with the general, and it is about the king." ”

"Please!"

In Zhang Guangchang's temporary tent, Xi Ci came in. As soon as he entered the door, he shouted: "General! The safety of Hengshan Country depends only on you! ”

Zhang Guangchang frowned: "I don't know what happened when the minister visited late at night?" ”

Xi Ci told Zhang Guangchang about Chun Yuyi's delivery of poison, and omitted Su Ren's section in the middle, and after the matter was finished, he continued: "This is the murder of the king, general, we are all courtiers of Hengshan Kingdom, we must not let this happen, and please ask the general to immediately lead troops to surround the post house and find out all those poisons, otherwise it will be too late!" ”

Zhang Guangchang immediately said: "What the minister said is very true, I will send someone!" ”

"The general has to go in person, which involves the queen and the county lord, and others are afraid that there will be mistakes! Only the general himself is in charge to be reassuring. ”

Zhang Guangchang thought for a while: "What the Minister of State said is right! Come on, immediately order a group of people and horses, and follow me to the Chengdong Station! ”

The military order fell like a mountain, Zhang Guangchang said a word, and the soldiers who were still sleeping were immediately called up. In the time of a cup of tea, a team of 500 people was assembled. Zhang Guangchang waved his hand, the city gate was opened, and the soldiers walked out of the city with neat steps and followed Zhang Guangchang out of the city.

With a smile on the corner of his mouth, Xi Ci watched Zhang Guangchang lead people away, get into his carriage, and ordered: "Go to Cuixiang Building, quickly!" ”
