"Very good, then you can talk about the function and plant form of Caowu!" Old man Qian's expression eased slightly, but he still looked cold, and what Li Feng said just now was really too arrogant!

Li Feng's face was not red, and he said slowly without panting, the question asked by the old man Qian was really sleepy and met a pillow, Li Feng remembered the characteristics and uses of hundreds of millions of plants and trees in his heart, and it was too pediatric to answer these questions. 、

"Could it be that this kid is a genius in Chinese medicine?" Old man Qian was slightly surprised in his heart, he didn't expect Li Feng to answer, but for such an arrogant student, he still had to find a way to clean up, this time he was going to ask a slightly more obscure one.

"That's a good answer, let me ask you again, what is the use of cinnabar grass?"

Li Feng frowned, and also understood that this old man Qian couldn't get along with him today, so he deliberately asked a question to make it difficult for him. However, if you ask about Chinese herbal medicine, I am afraid that Old Man Qian will miscalculate.

"Cinnabar grass, also known as red on the back, red under the leaves, and red greens. It is a whole herb of the Lamiaceae family, a perennial herb, up to 50 cm high. The stems are square, slightly branched in the upper part, and are finely pubescent.

Born in the shade and dampness of rocky mountains. Its main function is to cool blood and stop bleeding. Treatment of vomiting blood, coughing up blood, epistaxis, bloody dysentery, blood collapse, knife wound bleeding ......"

When Li Feng finished speaking slowly, the whole classroom became silent, Qian Feng looked shocked, to be honest, for individual Chinese herbal medicines, even he, a Chinese medicine expert who has been immersed in Chinese medicine for decades, may not remember clearly, let alone be able to say the plant form of each herb completely!

"Classmate, what's your name?" Qian Feng spoke again, maybe he was wrong just now, people are sleeping in their own class, which means that people don't need to listen at all, because people already know it clearly......

"Li Feng. ”

"Good, I remember. Qian Feng nodded, and then suddenly remembered something, and asked: "I have been researching a rare herb recently, but I have never seen it, I don't know classmate Li Feng, can you help me take a look?"

As soon as Qian Feng said this, the students in the entire classroom were stunned, could it be that the famous professor of Chinese medicine really wanted to ask a student?

Li Feng pondered for a while, then nodded slowly, and said, "I need to see the appearance of the herbs." ”

Qian Feng hurriedly took out his handbag from the drawer of the podium and took out an herb in a glass box from it.

Li Feng walked up to the podium, and the moment he saw the herbs, his face suddenly changed slightly, and he said, "Professor Qian, please stretch out your right hand, I will take the pulse for you." ”

"Pulse?" Qian Feng was stunned, but involuntarily stretched out his right hand.

Li Feng's right index finger and middle finger rested on Qian Feng's wrist, and after a moment of silence. Nodding.

Qian Feng looked dazed and hesitated: "Classmate Li Feng, what are you doing here? What is this herb?"

Li Feng let out a long sigh and said slowly, "Professor Qian, have you sometimes felt chills all over your body and weakness in your limbs recently?"

"W-How do you know this?" Qian Feng was shocked, "I do feel chills all over my body recently, my limbs are weak, and the blue spot under my lower abdomen has grown from the size of my thumb at the beginning to the size of my palm now, and it will hurt faintly if I press it." ”

Li Feng nodded and said, "That's right." Professor Qian, you've been poisoned!"

"Poisoning, how is it possible?" Qian Feng looked at Li Feng in disbelief with suspicion.

Li Feng sighed, pointed to the glass box on the podium, and said, "This thing is called Centennial Jasmine Root." It is an extremely rare poison, which is abundant in the peach blossom stream in southern Fujian, the peach blossom stream is in the nine doubtful valleys of Wuyi Mountain, the peach blossoms are everywhere, the wild jasmine on the side of the stream, the stream contains peach blossom miasma, the toxicity is very strong, the jasmine root is nourished by the stream water, and also contains poison. Collected for a hundred years, the miasma is removed, ground into powder, colorless and tasteless, eaten by people, and there is no sign of poisoning until death. Even the drug treasure "Jade Toad" cannot be tested for toxicity. At the beginning of the Song Dynasty, Taizong used this poisonous weed to assassinate Meng Chang, the general of Later Shu, and then began to circulate secretly in the world......"

Li Feng said slowly, but Qian Feng's face became more and more pale.

"This hundred-year-old jasmine root is extremely rare, I want to know where you got it from?" Li Feng suspected in his heart, maybe there was something deeper hidden behind this matter.

At this point, Qian Feng's face became extremely pale, but there was a sense of anger in his expression, and finally he took a deep breath and said: "Classmate Li Feng, thank you today, I want to ask you again after class, I don't know if you have time?"

"Of course, Professor Qian doesn't have to be polite. After Li Feng finished speaking, he turned around and walked back to his seat.

"Xiao Fengfeng, you are so good!" Ye Mei hugged Li Feng's arm and kissed him on the cheek without saying anything.

Lu Wei on the side was not to be outdone, and said with a shy smile: "Brother Feng, you are so amazing!" and then kissed the other cheek.

"Little Feng Feng, Brother Feng ......" Li Feng choked speechlessly, he felt the need to draw a line with the two of them, "Two beauties, in fact, I won't hide from you, I already have a girlfriend, so you can save your worries, okay?

Lu Wei was stunned for a moment, and her arm suddenly froze, "You have a girlfriend? Who is she?"

"Sister Lu Wei, this is not a beautiful thing, okay?"

Ye Mei on the side snorted: "I don't mind, I just want to fight with Su Xiaoling!"
