Sun Simiao looked at Li Su, his eyes full of doubts.

Li Su asked, "Mr. Liu, can you buy kelp here?" ”

"Kelp, what's the use of kelp?" Mr. Liu asked. He had heard of kelp, but he had never eaten it, and it was not easy for them to taste good, and they didn't like to eat kelp.

He asked the housekeeper, "Can I buy kelp in Nanyang City?" ”

The housekeeper said, "There is a seafood store in the east of the city, and there are those that are sold. ”

Li Su said: "Mr. Liu, when you eat, add a dish made with kelp, and persist for a while, and their illness will slowly heal."

When they are cured, they can prevent this disease by eating a little kelp every once in a while. ”

After listening to Li Su's words, Sun Simiao's eyes lit up, and he seemed to understand something.

Mr. Liu asked suspiciously, "Just eating these kelp can cure my wife and son's illness?" ”

Li Su told them the truth. Sun Simiao suddenly realized, and said with admiration: "How did Li Gongzi know such an esoteric medical theory?" Sun admired. ”

Wu Cong looked at his man, his eyes were full of adoring little stars, and he felt extremely proud, and he couldn't wait to go up and kiss his wise head.

Sun Simiao was also very excited, he said, "Gongzi Li, who is your ancestor?" ”

The number of people who practiced medicine in ancient times was very small, basically hereditary, the so-called son is not passed on to the daughter, and there are not many apprentices with foreign surnames, so he wants to ask the origin of this Li Gongzi in front of him, and see which medical family he is from.

Yang Kang was a little unhappy when he heard Sun Simiao's words. Listening to the meaning of his words, the ancestor of his own prince was a Lang Zhong who practiced medicine.

He said: "Mr. Sun said cautiously, my family's ancestors and practitioners have nothing to do with each other. ”

Yang Kang's sentence "My lord", Sun Simiao didn't care, but it frightened Mr. Liu's family. The person in front of him turned out to be a child of the clan, could it be a county prince?

Mr. Liu hurriedly stood up, saluted and said, "The grass people have seen the prince. ”

Sun Simiao also stood up and saluted, and he asked, "May I ask who you are?" ”

There is no need for Li Su to hide his identity, he said: "Mr. Sun, please take a seat, my name is Li Su, and this is my ninth brother Li Zhi." ”

Sun Simiao didn't care much about the government and didn't know much about the identities of the princes. His apprentice Liu Shenwei was more aware of the affairs of the imperial court, and he interjected and said, "Master, it turned out to be His Royal Highness the Crown Prince and His Royal Highness the King of Yangzhou. ”

Sun Simiao was about to stand up and salute again, but was stopped by Li Su. Li Su said: "The old immortal doesn't have to be polite. ”

Mr. Liu's family was frightened, and the benefactor in front of them turned out to be the famous Royal Highness the Prince. He hurriedly saluted Li Su and Li Zhi again.

Sun Simiao asked, "How is the queen's asthma?" "He had prescribed medicine to Empress Eldest Sun before.

Li Zhi said: "Mr. Sun, the queen mother's illness has basically healed. ”

Sun Simiao said suspiciously: "The queen's illness is born from nature and is extremely difficult to cure. Which gentleman prescribed the prescription, can you show the grass people? "He's very interested in that.

Li Zhi said: "It's my sixth brother, who treated the queen mother. ”

Sun Simiao looked at Li Su's gaze and became even more puzzled. He thought to himself, I have inherited the knowledge accumulated by my ancestors for hundreds of years, and I have spent nearly a hundred years exploring and researching medicine, and I can't compare to the young man in front of me. In addition to admiration, there is a feeling of being devastated.

He couldn't help but say, "Your Royal Highness, I don't know, do you have time, the grass people want to discuss the problem of medical science with you?" ”

Since Li Su saw their master and apprentice, his heart began to open their minds, and he smiled: "No problem, if it is convenient for you, old man, I will stay in Nanyang for a few more days and ask you for advice." ”

Over the next three days, Li Su and Sun Simiao discussed medical issues. Although Li Su knew little about medical problems, he relied on Baidu to discuss with Sun Simiao.

Sun Simiao is obsessed with medical research, he not only wants to wash away the prescription to cure diseases and save people, but also wants to write a book and pass on his medical research results to future generations.

Li Su opened Sun Simiao's two books, "A Thousand Golden Prescriptions" and "Tang Xin Materia Medica" from Baidu, and discussed them in a targeted manner. Li Su's narration solved many doubts in Sun Simiao's heart, and the more the two talked, the more speculative they became.

In the end, Li Su showed Sun Simiao the research results of traditional Chinese medicine in later generations, as if a bright window was opened in front of his eyes, showing a new world. aroused Sun Simiao's yearning.

At this moment, Li Su also thought that the time had come, and he proposed to continue south, and there was no time to continue to discuss with him.

Sun Simiao's heart was itching, and his eyes were a little affectionate when he looked at Li Su, and he was really reluctant to leave.

Li Su said: "Yes, Mr. Sun, I will stay there for 2 to 3 months when I go to Yangzhou this time, if it is convenient for you, I will go to Yangzhou with me, I will sort out some secret recipes of Chinese medicine for you, what do you think?" ”

Sun Simiao was overjoyed, and he said: "It is very convenient for the grass people to have time, so they will disturb His Royal Highness the Prince." ”

The medical level of the Tang Dynasty was very backward, and the medical resources of the whole society were very few. Li Su wanted to establish the highest medical school in the Tang Dynasty and improve the level of medical education. Sun Simiao and his apprentices are good founders.

Li Su sent someone to call the Nanyang County Order, left him a prescription for the treatment of big neck disease, and asked him to transfer it to the state thorn history. Then we got on the road.

Mr. Liu wants to sell his family property and hand over half of it to His Royal Highness the Crown Prince according to the prior agreement.

Seeing that he was sincere, Li Su not only did not ask for his property, but also wrote a letter to him, asking him to find Li Dan, the Minister of Industry, to give him some in-demand products and let him operate.

On the road, Li Su often discussed medical issues with Sun Simiao, and from time to time he came up with a Chinese medicine prescription, which made his old man itch and couldn't stop.

When Li Su and Sun Simiao discussed the problem, most of the time was carried out in Li Su's carriage. During this period, Wu Cong served tea and poured water for them on the side, and took care of them very thoughtfully.

Li Su is "knowledgeable", humorous in conversation, and the atmosphere is very harmonious. Sun Simiao is still a little childish, and sometimes he plays poker with them, and he will get angry if he loses. He enjoyed the atmosphere.

On this day, I finally came to the Yangzhou area. The state capital of Yangzhou is not in Yangzhou County, but in Jinling (Nanjing).

In ancient times, there were no bridges on the Yangtze River, and all boats were used to cross the river. Cheng Chumo, Huang Qi, Liu Renliang and others crossed the river in advance and waited at Pukou Wharf to greet His Royal Highness the Crown Prince and his party.
