After dealing with the personal feud between Ma Xuanzhong and Zhang Zhijiang, Liuyun took Liu Xuanxiao and rushed to Xu Xin's house to ask for marriage.

Although Xu Xin has already communicated with her family, Xu Xin's family is still flattered when they see Liuyun who came to the door to ask for marriage.

Xu Xin's family looked at Liuyun's expression, which reminded Liuyun of the surprise of "finally seeing a living person".

Especially Xu Qing, the younger brother of Xu Xin's family, followed Liuyun all day long, and asked questions whenever he found an opportunity.

Liuyun, who was asked a little "impatiently", took out a stack of test papers from his backpack and handed them to Xu Qing.

Liu Xuanxiao saw his father take out the test paper, and glanced at his future cheap brother-in-law in surprise.

Xu Xin, who rarely saw Liu Xuanxiao's surprised expression, gently rubbed Liu Xuanxiao.

Liu Xuanxiao sighed softly: "Xiao Qing'er is really lucky, senior brother has just transferred to Western medicine in surgery. Although the old man was dissatisfied, he could know from the name of the senior brother how much his father expected him. ”

Xu Xin asked tentatively, "Jin Cheng?" ”

Liu Xuanxiao sighed: "Senior brother, I used to be the one who was most likely to inherit my father's mantle of traditional medicine. ”

"What about him?"

"Although the qualifications of the senior brother are not the best, he has a lot of perseverance, but unfortunately because of his distractions, he can't reach the top."

Liu Xuanxiao knew very well the purpose of his senior brother's study of medicine, to treat diseases and save people, so once the senior brother met the Chinese Communist Party, it was inevitable to change to surgery.

But Liu Xuanxiao also knows very well what kind of person his father wants: a person who can pass on what he has learned.

Although there is no conflict between healing and saving people and passing on skills, there is a sequence.

As a historian, Liu Xuanxiao knows very well that his father holds a lot of lost medical skills in his hands, and there are many skills that can only be understood by heart and cannot be seen on paper, such as high-level Zhuyoushu.

Xu Xin knew very well that his younger brother was indeed very interested in herbs that could cure diseases, and because the family had been in the medicinal herb business for a period of time, he had also prescribed prescriptions according to medical books, but the results were not satisfactory.

Liuyun took the paper and quickly finished the score.

Seeing that everyone was staring at him, Liuyun looked at Xu Qing with a smile: "Are you interested in being my apprentice?" ”

"Little Fan Brother" looked at Liuyun in surprise, lowered his head, thought for a while, and responded to Liuyun, but his voice was a little low: "I have prescribed medicine, and it is completely according to the prescription, and there is no problem after asking the old gentleman the dosage, but why, it doesn't work very well?" ”

Liuyun asked confidently: "Is there artificially planted medicinal materials in the prescribed medicine, and the cultivation history of this medicinal material is very long?" ”

Xu Qing nodded in surprise.

"Want to know?"

Hearing the tone of his old man, Liu Xuanxiao understood that his cheap brother-in-law was about to become his own junior brother.

Xu Qing nodded.

Liuyun took out a silk scroll from the wide sleeve of his robe, handed it to Liu Xuanxiao behind him, asked him to hold it, and then stared at Xu Qing with a smile: "Kowtow three times first, and then pour me a cup of tea." ”

The people of the Xu family were stunned: There is still this kind of operation?

Seeing that Xu Qing was a little confused, Father Xu kicked him behind him.

Xu Qing kowtowed three times in a daze, took the teacup handed over by his father, and handed it to Liuyun.

Liuyun took the teacup, took a sip of tea, then put it down, and glanced at Xu Qing quite proudly: "You can call me Master." ”

"This ......" Xu Qing was still a little confused.

"Still don't want to?" Liuyun stared at Xu Qing with a smile, "There are many people crying and shouting that they want to worship me as a teacher, but you don't want to?" ”

"Evil Barrier!"

Father Xu kicked Xu Qing's leg in the crook of his leg and directly kicked him to his knees.

"Oh, by the way, I'll answer your question first."

Liuyun picked up the teacup, took a sip, moistened his throat, and helped Xu Qing up: "Have you ever learned the "Theory of Heavenly Evolution" that is strict?" ”

Xu Qing nodded.

"What about Darwin's The Origin of Species?"

Seeing Xu Qing nodding again, Liuyun nodded with satisfaction: "Then I'll tell you about the origin of the medicine first." ”

Since ancient times, I don't know how many years have passed, the Chinese people have discovered certain plants, which have a special effect on certain diseases, so there are medicinal materials.

After thousands of years of continuous experimentation and improvement, a practical science has been formed - Chinese medicine.

After talking about the history of traditional Chinese medicine, Liuyun asked the people present, a question that no one had ever asked before: "Where did the medicinal properties of the original medicinal materials come from?" ”

Hearing the question, Xu Xin was stunned, because she had seen the paper last year.

Xu Xin glanced at her little brother and was very happy to see that he had realized something.

"The earliest medicinal herbs, with their unique medicinal properties, were born in the process of rebelling against nature."

There was no trace of a smile on Liuyun's face, only unprecedented solemnity: "All medicinal herbs are grown in an extremely special environment. In order to survive, after tens of millions or even hundreds of millions of years of evolution, a special mechanism against nature was born. Some of the substances in this special system are medicinal properties. There are medicinal properties, but each medicinal material will have different medicinal properties, and these medicinal properties are not all what we need, so there are kings, ministers, assistants, and envoys. ”

Speaking of this, Liuyun changed his words: "However, collecting medicine is not a very easy job, so some people are lazy and come up with the cultivation of medicinal herbs, which is both labor-saving and profitable." As I said, medicinal properties come from fighting nature. Born in sorrow, died in peace, with a comfortable environment, medicinal herbs do not need to fight against the cruel natural environment, like a wolf domesticated into a dog, gradually lost its wildness, after a long comfortable days, the medicinal properties of medicinal herbs gradually faded......"

Xu Qing nodded, and shouted "Master" convincingly......

After solving his son's marriage, Liuyun took the stolen apprentice and quickly went north, and then returned to Qinghai, for fear of being snatched away by others.

When Liuyun returned to Qinghai, Liu Xuanqi, who was busy with cholera, was already waiting at home.

Liu Xuanqi, who is usually more cheerful, did not ask for credit and rewards when submitting the infectious disease investigation report as before.

Liuyun, who had experienced several large-scale infectious diseases, naturally knew that his daughter was stimulated, and asked softly: "Sixth, are you okay?" ”

Liu Xuanqi cried directly, even crying and scolding, and also said violently: "Although, I have long known that the northwest is poor and closed, but even washing hands before meals, such a little common sense, you also need to pay for tuition, what is going on?" ”

……

Liu Xuanqi, who had been venting for a while, had a snot flow, and when he saw Liuyun handing over the handkerchief, he brought it over.

Seeing Liuyun staring at him with a smile, Liu Xuanqi glared at his old man angrily: "When I came to leave, many ordinary people gave local products, but I thought they put my portrait at home to ward off evil spirits, so I didn't ask for it." ”

Yo, knowing that he had asked for a reward in a roundabout way, Liuyun glanced at Liu Xuanqi curiously: "Say, what reward do you want?" ”

Liu Xuanqi shook his head.

"Okay," Liuyun looked at Liu Xuanqi meaningfully, "Sixth, have you heard of penicillin?" ”

came to play meat, Liu Xuanqi stood up his ears.

Knowing that the old man in his family has a lot of good things, but the old man even knows that antibiotics are such a tall thing, Liu Xuanqi was a little surprised......
