Yu Yi looked at Hua Tuo's appearance again, he looked no different from an ordinary old man, and even more vicissitudes, but he always had a smile on his face, which made people not easy to get angry.

"What are you doing here?"

Yu Yi saw Wei Gang coming over with a pair of centaurs, and hurriedly asked.

"I'm here to see the excitement, I heard that someone is going into the city?"

Wei Gang replied.

"Haha, it's this old man, didn't you see it?"

Yuyi introduced the old man next to Wei Gang, and at the same time instructed the left and right to hurry up and find water to quench the old man's thirst.

"That's him, come on, arrest me!"

Wei Gang looked the old man up and down, then his face changed, and he gave an order to arrest the old man.

"Don't be rude, don't you know who this old man is?"

Yuyi stood in front of Hua Tuo and helped him block the officers and soldiers.

"I don't care who he is, I see that he is suspicious, I am afraid that he is a spy among the thieves, ready to lurk in our giant deer city like this."

Weygand still insisted on his opinion.

Yu Yi thought about it, how could this Wei Gang know that Hua Tuo needed people.

Hua Tuo is one of the few outstanding surgeons in the history of medicine in China, who is good at using anesthesia, acupuncture, moxibustion and other methods, and is good at thoracotomy and abdominal surgery. Surgical methods are not the mainstream treatment method of traditional Chinese medicine based on the culture of "respecting Confucianism", and under the Confucian idea of "the body is the skin of the body, the parents are the parents", surgery has not been developed on a large scale in traditional Chinese medicine. Some medical historians have verified that the treatment methods used by Hua Tuo are recorded in Indian medicine, and the main medicine "Mandala Flower" used in Ma Boiling Powder is also produced in India, so they propose that Hua Tuo traveled all over the Central Plains throughout his life, and he is likely to be a Tianzhu doctor from India.

This kind of person who is quite famous in history, isn't God helping me when he comes to Julu City.

But as Wei Gang, who is the head of the big catch, he has the responsibility to investigate the suspicious people who come and go, and he should have also discovered that Hua Tuo was able to come in through the West Gate, and in a normal physical condition, there must be something outstanding about him, which added some suspicions.

When he was in a dilemma, he brought the requested water to the left and right, and Yuyi took it and handed it to Hua Tuo.

He thought for a while and said to Wei Gang: "Do you remember the three-day appointment between Huang Wenjie's county order and me, didn't you promise to help me?" ”

Wei Gang replied: "That's true, but what does it have to do with this person." ”

In order to make a difference, Yu Yi secretly pulled Wei Gang to a corner, and after making sure that the others couldn't hear it, he said softly: "You don't know this person, he is my friend, a very famous doctor, he is to inform us about the situation in Julu County, and he came to visit me." ”

Wei Gang patted the back of his head, smiled, and said, "So that's the case, then you should have said it earlier." ”

Yu Yi smiled, as if thinking of something, and asked, "How did you get the news?" ”

"It was Huang County Ling who told me, he said that there was a suspicious person in Ximen, let me take a look!"

Wei Gang replied based on the facts.

In this way, Yuyi will figure out the situation, Huang County's order may not have been calculated, after an in-depth communication, Yuyi and Wei Gang have narrowed the distance, and some things are easy to negotiate.

"Okay, you can go back and just say that it's a friend of mine in Daoxiang Village, so that he won't embarrass you."

Yu Yi made up his mind and suggested to Wei Gang.

After hearing this, Wei Gang also adopted Yuyi's suggestion, and left from the West Gate in a hurry with the team.

After Hua Tuo drank the water, he felt a little uncertain, but when he saw Wei Gang leaving with someone, he knew that Yuyi had played a key role, and he hurriedly thanked him, but there were some things he didn't understand, so he still asked, "I met Your Excellency for the first time, why do you want to defend me so much?" ”

"They don't know about you, but I know your name, and I hope you don't take their rudeness to heart."

Yu Yi looked very modest.

Hua Tuo was still a little doctor at this time, that is, he was not famous, and he was very embarrassed about the name that Yu Yi said.

Yu Yi read something from his demeanor, then changed the topic, he took Hua Tuo to the area of the West Gate, and asked as he left, "Dare to ask sir, what kind of infectious disease is this?" ”

Hua Tuo encountered some symptoms when he entered from the West Gate, but after all, he was a famous Chinese medicine practitioner, and he had a set of methods for self-protection, but how to treat this disease, he still had no clue, and when he heard Yu Yi say this, he thought that he had met a peer, and he was very happy.

After he asked Yu Yi for his name, he casually asked about Yu Yi's situation, and Yu Yi just told Hua Tuo about the fact that he had read some entry-level Chinese medicine books, and he didn't know some advanced medical skills.

Hua Tuo nodded, he put forward his own opinion on the condition, he mentioned that the specific symptoms of this condition are initially lymphatic lumps in the groin or armpits, and then, blue-black herpes will appear on the arms and thighs and other parts of the body, and the disease is highly contagious.

Combined with Hua Tuo's observation, Yu Yi also realized his own gap, he only saw the symptoms of high fever, and they were all observed from a distance, Hua Tuo's conclusion must have been in personal contact with specific patients.

He couldn't help but give Hua Tuo a high evaluation.

Hua Tuo's description of this symptom also made modern people Yu Yi take some modern thinking, Yu Yi had seen this disease in the history books, called the Black Death, in the European Middle Ages, this disease swept across Europe, so that the population there plummeted by more than half, almost exterminated them, and the people at that time were helpless, exhausted all strange treatments. Some people eat feces and ashes, some remove black lumps, and some even put live toads on their chests.

However, these were all Yu Yi's guesses, and he exchanged some ideas with Hua Tuo.

Yu Yi's theories were very advanced in that era, and only a famous doctor like Hua Tuo could comprehend them, but he didn't know what the Black Death meant, so he asked. Yuyi also patiently answered that the Black Death was actually the plague, which was a very strong infectious disease.

After Hua Tuo knew that it was the plague, he seemed to suddenly realize that during this time, he had been exploring the source of this disease, and the appearance of Yuyi helped him completely figure out this problem.

Hua Tuo continued to ask about the treatment plan for this condition, and Yuyi naturally didn't say anything, because in modern times, there is this vaccine, and many people have no problem after vaccination, he just passed it off, saying that there is actually no treatment.

When Hua Tuo heard Yuyi's statement, he did not give up hope, but turned to a specific sick person in the Ximen area.
