Zhou Yi smiled faintly and ignored Liu Yaru's sharp words. Instead, he looked at Liu Zhengxiong seriously and said, "uncle Liu, this thing is really longan meat, but you don't recognize it."

"Zhou Yi, that's enough! If you want to pretend, please change your place to pretend. Don't make a fool of yourself in front of me. I Liu Yaru don't eat this set. Do you think you can attract my favor by pretending to know very well about medicinal materials? Do you think you can make me think you're rich by giving shopkeeper Cai 30000 yuan for nothing?" Liu Yaru was completely angry when Zhou Yi heard that pitcher grass is longan meat, Zhou Yi impressed her badly today. She can't bear it anymore.

Moreover, at the thought of not giving Zhou Yi a good look today, Zhou Yi will certainly have the cheek to go to Longcheng with her. Liu Yaru can't help it anymore. She must uncover Zhou Yi's hypocrisy here today to let Zhou Yi understand that she is not so easy to provoke or cheat, and completely cut off Zhou Yi's idea of following her to Longcheng to stick to her.

Seeing Liu Yaru get angry, Zhou Yi's look cools down. He doesn't know where Liu Yaru's self-confidence or sense of superiority comes from. He feels that he is pursuing her. At present, he loses his princess temper in front of him. He really thinks that Zhou Yi is paper paste.

"Yaru, stop it. Xiao Zhou just doesn't understand medicinal materials. He doesn't pretend to force." Liu Zhengxiong's face is also a little bad. Only then did he react that Zhou Yi may be pursuing Liu Yaru and deliberately attract his daughter's attention through this series of behaviors.

After thinking about it, Liu Zhengxiong's last favor for Zhou Yi suddenly disappeared. Liu Zhengxiong doesn't like Zhou Yi's free spending with his parents' money, and even now Zhou Yi is still pretending to be knowledgeable, which makes Liu Zhengxiong even more disgusted.

But he is an elder after all. He can't watch his daughter scold the street with boys, so he speaks for Zhou Yi. However, like Liu Yaru, he hates Zhou Yi.

"Liu Yaru, although I don't know where you came from, I feel confident that I am attracting your attention, but I Zhou Yi said I can identify medicinal materials, then I will!" Zhou Yi said clangly, with a trace of disgust for Liu Yaru in my heart.

"Hum, I'm Liu Yaru. I'm not blind. I've reached this point. You still don't know how to repent. I really don't know how your face is so thick. You said you can recognize medicinal materials. Then tell me how you recognized longan meat?" Liu Yaru said coldly. She knew how to identify longan meat, so she was sure that the grass in front of her was not longan meat at all.

"OK, I'll show you who is blind today!" Zhou Yi said coldly, taking the medicine out of the bag.

"The root of longan meat is like earth color, and the touch is smooth. Most of the liquid in it is light red and has strange fragrance. Uncle Liu, am I right?" Zhou Yi looked at Liu Zhengxiong and calmly opened his mouth. This is the way most people recognize longan meat. Through color observation, touch and even cutting, they can judge the color and flavor of the liquid medicine.

Hearing Zhou Yi's words, Liu Zhengxiong frowned. This week, Zhou Yi really knew how to identify longan meat.

"So what? Zhou Yi, do you want to call a deer a horse? The root of the medicinal material in your hand is black and feels like a tree trunk. At a glance, it's not smooth at all. I don't even have to cut it to know it's not longan meat." although Liu Yaru was surprised that Zhou Yi really understood, she was still stubborn and believed her judgment, There is nothing in Zhou Yi's hand that conforms to the characteristics of longan meat.

"Call a deer a horse? It's a horse. Why should I say it's a deer?" Zhou Yi said coldly.

"Zhou Yi, are you blind? Judge according to the characteristics of longan meat you said. What is the consistency of the medicinal material in your hand?" Liu Yaru was almost mad. Zhou Yi didn't repent now.

"Liu Yaru, who said that the root color of longan meat must be earthy? Do you think what is said in the compendium of Materia Medica is right!" Zhou Yi asked with a sneer.

"Zhou Yi, I didn't expect that you have no idea of heaven and earth. The compendium of Materia Medica was written by the medicine King Li Shizhen. You even dare to doubt the ancient medicine king! Should I call you Zhou medicine king instead?" Liu Yaru said sarcastically.

Liu Zhengxiong also frowned. Now he feels that Zhou Yi is becoming more and more unreliable. The medicine King Li Shizhen's understanding of medicinal materials is the first person in China. His lifelong experience is recorded in the compendium of Materia Medica. Now, no one in China dares to question Li Shizhen even if it is a famous contemporary doctor, but he doesn't want Zhou Yi to directly say that the compendium of Materia Medica is wrong today.

"You can call me the king of medicine of Zhou. I can afford the name of the king of medicine." Zhou Yi said calmly. According to his Dandao cultivation in the starry sky in his previous life, on this earth, let alone the king of medicine, is the God of medicine.

"Talk big!" Liu Yaru's crisp chest trembled angrily, pointing to Zhou Yi's fingers. "Dad, let's go. I don't want to say more to such people!"

"Xiao Zhou, you've gone too far. Anyway, you should be in awe of the elder Yaowang. You're wrong about his lifelong research." Liu Zhengxiong also spoke coldly and was very dissatisfied with Zhou Yi's rampancy.

Liu Zhengxiong's father and daughter said that they would leave with a cold face. Unexpectedly, as soon as they turned around, a strange fragrance went straight into their nose!

What is this? The smell of longan meat!

Liu Zhengxiong and his daughter had this idea in their hearts, and then looked at each other incredulously.

"Liu Yaru, what about now?" Zhou Yi's faint voice came over.

Liu Yaru's shoulder trembled, turned around and saw a scene that she would never forget!

There was a bright blood red in the middle of the black medicinal material just now! Like dragon blood!

Liu Zhengxiong also swallowed his saliva and looked at the medicine in Zhou Yi's hand in shock. The strong aroma from the blood red was the same as that of longan meat, and even the aroma was more refined. Liu Zhengxiong felt refreshed after just taking a few mouthfuls.

"This... How is this possible!" Liu Zhengxiong said in shock.

Liu Yaru also rubbed her eyes and looked at Zhou Yi's hands, which were still black medicinal materials. She was shocked that there was really black longan meat!

"How could it be impossible?" Zhou Yi asked. Even though Li Shizhen is a generation of medicine king, he is a mortal after all, and what he sees and hears has limitations. Take longan meat for example, it is difficult to have more than 20 years on earth. Most of the longan meat Li Shizhen saw was about 10 years, so Li Shizhen decided that the longan meat was earthy yellow and the touch was smooth.

Li Shizhen's conclusion is really no big problem on earth, but if this conclusion is taken to the star sky, it will definitely be laughed off, because most of the longan meat in the star sky is more than a century old, and even the longan meat with more than a thousand years of colorful magic light, but it already belongs to the category of divine medicine. Even Zhou Yi has not seen a few in his previous life.

But Zhou Yi has seen 50 years of longan meat, so he saw at a glance that what shopkeeper Cai had in his hand was really good. Judging by what was in the compendium of Materia Medica on earth, Liu Yaru and Liu Zhengxiong were doomed to miss the 50 years of longan meat.

"How do you... How do you judge? Why is black root also longan meat?" Liu Yaru asked bitterly. She has admitted that this medicinal material is indeed longan meat, because the core of longan meat is blood red and exotic fragrance, which can't be compared with its appearance.

"Why can't black root be longan?" Zhou Yi sneered. Liu Yaru still refuses to believe that there are mistakes in the compendium of Materia Medica. "Why, do you still think the compendium of Materia Medica is right?"

Liu Yaru stopped talking and Liu Zhengxiong stopped talking for several times. After all, Zhou Yi suddenly destroyed their decades of cognition. What they once regarded as truth was wrong. Liu Zhengxiong's father and daughter couldn't accept it for a moment.

"As I said, the compendium of Materia Medica is not necessarily right. Take this longan meat for example. Most longan meat is indeed as Li Shizhen said. Its root is earthy yellow and feels greasy, but it is only about 20 years after all."

"Li Shizhen doesn't know that there are more than 20 years of longan meat. Once the longan meat exceeds 20 years, its root color will change from earthy yellow to cyan, and then black. The longan meat in my hand is black, and its age has been at least 50 years."

Zhou Yi's calm words set off a huge wave in the hearts of Liu Zhengxiong's father and daughter. There are at least two kinds of longan meat: cyan and black! Moreover, this one in front of Zhou Yi is actually 50 years old. How much is it worth.

"Xiao Zhou, where did you see this knowledge?" Liu Zhengxiong asked in shock.

"In an ancient medical book."

"Ancient medical books?" Liu Zhengxiong's eyes lit up and continued to ask, "what ancient medical books have a deeper understanding of pharmacology than Li Yaowang."

"I forgot, but I accidentally turned it over, and then I lost the book." how can Zhou Yi not know Liu Zhengxiong's idea and can't give Liu Zhengxiong the chance to hit a snake with a stick.

"Alas, it's a pity that this kind of divine book has been lost." Liu Zhengxiong sighed and shook his head.

"Xiao Zhou, can you sell your longan meat to uncle Liu? Uncle Liu offered 500000!" it seemed that Liu Zhengxiong thought of something and bewitched him.

Liu Yaru's eyes lit up when she heard her father's words. The ten-year longan meat is worth 200000. I'm afraid the price of the fifty year longan meat is unimaginable!

Zhou Yi shook his head and said, "uncle Liu, I still use this longan meat. I can't sell it to you."

"600000, Xiao Zhou, this longan meat can only be cooked according to the medicinal properties of traditional Chinese medicine and other medicinal materials. You can't do it yourself." a touch of treachery flashed in Liu Zhengxiong's eyes, adding 100000 to tempt Zhou Yi.
