In a moment, the doors of the two shops were removed, and the room was much brighter.

Wang Dingren stood outside the door with his hands in his hands, followed by his grandson Wang Yuexuan behind him. Wang Yuexuan was carrying a big wooden box on his back, and he was still holding a five or six-year-old child in his arms, who was it not Li Shizhen!

Li Feibai welcomed the three of them into the shop and sat down as guests.

Wang Dingyi thought that Li Feibai would definitely see how the cool oil was made, but saw Li Feibai get up from his seat again, picked up Li Shizhen and walked around the room, and said happily: "Little guy, why are you here too?" ”

Li Shizhen said: "Grandpa Wang's yard is nothing interesting, I heard that they were going to enter the city, so I followed." Grandpa Wang said that you are in business, why don't you see something to sell in your shop? ”

Li Feibai said: "Everything is sold out!" ”

Li Shizhen said: "Then you are so powerful!" ”

Li Feibai said: "You are even more powerful!" ”

Li Shizhen said: "I'm just a child, what's so powerful?" ”

Li Feibai was speechless for a moment, not knowing how to answer. Wang Dingyi: "Xuan'er, you take Shi Zhen to the street, and buy him some fun and delicious food by the way!" ”

Wang Yuexuan stepped forward and hugged Li Shizhen out. Li Feibai watched Li Shizhen go away, and then he sat down next to Wang Dingyi, and after the two drank a cup of tea, Wang Dingyi said: "You like Li Shizhen very much?" ”

Li Feibai said: "Yes, such a pleasing child, who doesn't like it!" ”

Wang Dingyi: "Gratifying? Annoying, right? This little guy, when he sees any medicinal herbs, he has to ask the root cause to understand, and he asks about the medicinal properties and what diseases can be cured, and if you explain it a little vaguely, he will be like a chattering old woman in your ear, and he will keep asking. ”

Li Feibai said: "So he is very talented in medicine, and with a little training, he should be a famous doctor who is not born in the world!" ”

Wang Dingyi nodded slightly, sighed and said: "I think so too, but his father thinks that studying and becoming an official is the right way, and he doesn't want him to study medicine!" ”

Li Feibai said: "What's going on? ”

Wang Dingyi: "Alas, it is also the profession of a doctor that makes Li Yanwen heartbroken!" What's the use of your medical skills? He won't slip around and shoot horses, he won't bribe, and he will always be just a person in charge of medicinal materials. What if you pay a bribe? At most, he is only an eight-grade imperial doctor, and he is in charge of your six-grade court judgment and five-grade court envoy, but in fact, they are all literati who don't understand medicine. But you know that this prescription is useful for patients, but if they don't like you, they will make it difficult for you in every way, and you can't use this, and you can't use that. In the end, the disease is not cured, but you are blamed for your incompetence. ”

Li Feibai said: "Grandpa Wang, I seem to have heard that you are the imperial doctor of the sixth grade, why did you become the eighth grade?" ”

Wang Dingyi: "That was after I was promoted to the sixth grade." ”

Li Feibai sighed "oh" and said: "A layman leads an insider." ”

Although Wang Dingyi heard this sentence for the first time, he could understand what Li Feibai meant after a little pondering, and said, "Yes! In fact, all walks of life are not like this, do the people in charge of iron smelting understand iron smelting? Does the salt road steward know how to make salt? When I was in the Tai Hospital, relying on the qualifications that I had worked in the Tai Hospital for decades, those hospitals gave me some face, and they didn't dare to refute my words, and Li Yanwen did a comfortable job under me. I just left the capital, Li Yanwen has no one to support him, and he has been punished seven or eight times in a short period of time, and he is about to be punished. Therefore, he simply quit and wanted to go home and deliberately train his son to be admitted to the sergeant and become an official, and he would no longer be affected by this bird's spirit! ”

When Li Feibai heard that Li Yanwen was going to take Li Shizhen home to study and be admitted to the rank of sergeant and official, his heart couldn't help but tighten. It's not that Li Shizhen is nervous that he will give up medicine in order to be admitted to the military and become an official, then there is no medical wonder book "Compendium of Materia Medica". After all, even if he didn't cross over, Li Yanwen would still leave the Tai Hospital and take his son home to take the Jinshi exam, it turns out that it is not so easy to take the Jinshi exam, Li Shizhen did not pass the exam after all, but wrote the Compendium of Materia Medica. He was nervous that Li Yanwen was going home.

Li Feibai didn't know where Li Yanwen's family was, but it was definitely not from Jiyuan. If Li Yanwen took Li Shizhen home, how could he plant a seed for Li Shizhen, and then cultivate it carefully, and then grow a modern medical system.

So, he asked, "Is Li Yanwen still going home now?" ”

Wang Ding smiled and said, "What do you say? ”

Li Feibai knew that Wang Dingyi left Li Yanwen behind, and said, "Since Uncle Li is completely disappointed in his profession as a doctor, how can Grandpa Wang persuade him to stay?" ”

Wang Dingyi: "Leave a name in history!" ”

Li Feibai can already guess the process now. Thinking about it, Wang Dingyi knew that a person could not study anesthetics and painkillers, and it happened that Li Yanwen came to visit. Wang Dingyi knew Li Yanwen's pharmaceutical methods, so he strongly asked Li Yanwen to stay and help. But Li Yanwen was heartbroken, and he didn't want his son to follow his old path again, so he must go home to train his son to study and take the Jinshi exam. In the end, Wang Dingyi introduced the anesthetic needle to Li Yanwen, and tempted him to leave his name in Qingshi, Li Yanwen couldn't resist the temptation, so he agreed to stay. As for Li Shizhen, where to study is not to read, and Jiyuan is not so barren that there is no county school.

As long as Li Shizhen stays in Jiyuan, Li Feibai can plant a seed for him. And the question that Li Yanwen doesn't want Li Shizhen to study medicine is actually not a problem! If the sons of the world can live according to Lao Tzu's wishes, then the sons are all jinshi and officials, and where do they get the three hundred and sixty lines.

Wang Dingyi said again: "I am using your spear to attack the shield of words and hearings." I didn't expect this spear to be invincible, and it could attack both my shield and the shield of words. After speaking, the two looked at each other and smiled.

Wang Dingyi pulled the wooden box that Wang Yuexuan carried, opened it and took out a small round box from inside, handed it forward and said, "Look, what is the difference between the cool oil we make and the one made by strange people?" ”

Li Feibai took the small round box but did not rush to open it, but became interested in the box. The box, which is three times larger than his cool oil box, is carved out of wood, perhaps due to time or cost, and is only polished and smoothed, without carving patterns.

The texture of the wood is also very good, with black lines in the yellow and a faint medicinal fragrance.

Li Feibai pointed to the box and said, "This ......"

Wang Dingyi: "Your cool oil is made of iron sheets, and you won't be able to make such a delicate thing for a while, so you will temporarily use wood for emergencies!" ”

Li Feibai said: "I'm not asking this, I'm asking what kind of wood this is and why there is a medicinal fragrance." ”

Wang Dingyi: "This is a cypress tree, and its fragrance can calm the mind." After a pause, he said: "That day, after you left, I thought about what to use to hold the cool oil, and after falling asleep in a daze, I thought of it as soon as I woke up." Cool oil has the effect of cooling and dissipating, relieving itching and pain, refreshing and refreshing the brain, and cypress also has the medicinal effect of clearing heat and relieving dryness, refreshing and analgesic, which is a perfect match with it. Moreover, with this thing in the person's arms, it is also a good handle, and it is always held in the hand to play, which can make this box want to shine and shine, and I can't put it down! ”

After listening to Wang Dingyi's words, Li Feibai was even more sure of one of his previous thoughts. At this time, people are not stupider than themselves, on the contrary, they are much smarter than themselves. Many of the products I thought of before seemed to be impossible and impossible to make in this era, because I only wanted to do it on my own, and naturally I couldn't do it. But if you find some smart people to do it, even if you can't make exactly the same product, you can find alternative products, as evidenced by the cool oil box.

He opened the box, sniffed the cool oil inside, dipped some with his fingers, and gently wiped it on the back of his hand.
