In Zhao Yan's study, Cao Tong and Zhilugu, who had already eaten breakfast, sat there with a curious expression, Zhao Yan took down his medical box from the bookshelf, and then took out a used syringe from it and put it on the table and said: "Two of you, please see, this is called a syringe, it was originally a tool for injecting medicine into the patient's body, so as to treat diseases, I used this syringe to inject the saliva of a mad dog into Zhang Renxian's body, so that he contracted rabies." ”

Cao Yan previously proposed to be interested in Zhao Yan's method of letting Zhang Renxian contract rabies, and Zhao Yan also felt that there was nothing to keep secret, after all, whether it was Cao Yan or Zhilugu, both of them knew rabies very well, even if Zhao Yan didn't say it, the two of them could guess some, so there was nothing to hide at all.

Cao Tong and Zhilugu heard Zhao Yan's words, and then looked at the syringe on the table, both of them showed curiosity on their faces, among which Cao Tong even reached out and picked up the syringe and studied it, and the result is that although the principle of this thing is simple, it is not simple to make zuò, especially the hollow needle in front, I am afraid it is difficult to make it.

I saw Zhilugu take the syringe from Cao Tong's hand and study it, and then suddenly sighed and said: "This syringe is not easy to make, it was originally a tool for saving people, but now it is used to kill people, I hope the king of the county will use it to save more people in the future!" ”

Hearing that Zhilugu was still a little dissatisfied with his use of medical skills to kill people, Zhao Yan didn't get angry, but said with a wry smile: "Doctor Zhishen doesn't know, this syringe can only be used once when saving people, otherwise it may bring danger to the patient." And the drugs used for injection cannot be manufactured, so these syringes cannot be used to save people in the future. ”

"Can't make it?" Zhilugu was stunned for a moment when he heard this, and then asked rhetorically, "Where did the syringe and medicine in the hand of the county king come from?" ”

"This ......" Zhao Yan hesitated for a moment, the true origin of these things naturally can't be told to sù Zhilugu, and even the lie of meeting the immortal can't be told to the other party, so he finally shook his head and said, "This matter belongs to the secret of my Great Song Dynasty, so Xiao Wang really can't tell him!" ”

Hearing Zhao Yan say this, Zhilugu was a little disappointed. But he didn't ask any more questions. However, Cao Yan was very interested in this matter, he was the former uncle of the Great Song Dynasty, and he was Zhao Yan's elder, so Zhao Yan couldn't sue him. It should be possible to sue sù yourself. He planned to ask about it when he had the opportunity in the future.

figured out Zhao Yan's method of killing. Cao Tong and Zhilugu were not satisfied, but began to discuss rabies with Zhao Yan, which had many causes. There is no abnormality at all in the incubation period, once the disease is extremely ferocious, it can kill people in just a few days, and even Cao Tong and Zhilugu have no cure for this, at most they can save the patient's life, but it will leave the sequelae of Yan zhòng, such as that Zhang Renxian is worse than death.

Cao Tong and Zhilugu thought that Zhao Yan could use rabies to kill people, and they knew some novel medical skills, so they hoped to find a way to restrain rabies from Zhao Yan, but to their disappointment, Zhao Yan was also helpless against rabies, unless he was given a rabies vaccine, so that the body could produce antibodies during the incubation period, so that he would not have to worry about getting sick, but this was obviously unrealistic.

"Doctor Zhishen, there is one thing I have never been able to understand, once rabies is sick, it should be ten deaths, how did you save Zhang Renxian's life?" Zhao Yan asked very curiously at this time, this question has been bothering him for a long time, and now that he can see Zhilugu, he naturally wants to ask clearly, after all, this is a medical problem that has not even been solved in later generations.

"I'm not straight!" Zhilugu protested dissatisfied, but for Zhao Yan's question, he finally replied, "As for the method of saving Zhang Renxian's life, it is mainly because I used two treatment methods, the first is to use the acupuncture technique of our Zhilugu vein to stimulate Zhang Renxian's vitality, so that he can temporarily suppress the condition in just a few days, and the second is to take out the brain of a mad dog and smash it, and then cut a wound on his body with the method of poison attack, and then apply the brain of the mad dog, this treatment method has been used for ancient times, The legend was created by Ge Hong, but the risk is very high, and I also relied on my own acupuncture skills and great luck to save Zhang Renxian's life! ”

Needless to say, Zhilugu's acupuncture technique was seen in the empty space before, and the acupuncture of the empty was learned from Zhilugu, so it can be seen that Zhilugu's acupuncture technique must be more subtle and magical.

As for the method of applying the wound with the brain of a mad dog, it also opened Zhao Yan's eyes, because the brain of a mad dog contains a large amount of rabies virus, which is several times more than the content in saliva, if such a thing is applied to the wound, I am afraid it will be more powerful than saliva, but I don't know if this theory of fighting poison with poison is reliable.

Thinking of this, Zhao Yan raised his own questions about whether it is reliable to fight poison with poison, after all, whether it is Cao Tong or Zhilugu, both of them are a generation of medical masters, and with such an opportunity, Zhao Yan naturally wants to ask for advice.

It's just that for Zhao Yan's question, Cao Tong hesitated for a moment before saying: "Son-in-law, we actually rarely use the method of fighting poison with mad dogs, because the risk of this method is too great, and only one in dozens of people can be effective. ”

Zhao Yan also nodded and said to himself when he heard this: "I see, it seems that this Ge Hong is really powerful, he actually guessed that the mad dog has the rabies virus on his body, so he came up with this way to restrain the virus." ”

Although Zhao Yan's voice was soft, Cao Tong and Zhilugu heard it, and both of them looked at each other in surprise at the moment, and then Zhilugu took the lead in asking: "Your Royal Highness, what kind of virus is the virus you said just now, could it be that the poison on the mad dog is this virus?" ”

"Huh?" Hearing Zhilugu's question, Zhao Yan was also obviously stunned, and then he explained helplessly, "The virus is not a certain poison in the understanding of the two, the virus is actually a tiny creature, almost all kinds of viruses exist around the environment we live in, and some viruses invade our body, which will cause some diseases, such as wind chill, smallpox and other diseases, which are caused by the corresponding virus." ”

"This ...... How is this possible? In the theory of traditional Chinese medicine, the main cause of human illness is the five elements of yin and yang and the theory of qi and blood, in the view of traditional Chinese medicine, the balance of yin and yang in the human body, if it is unbalanced, it will lead to diseases, and it may also be invaded by evil qi, which will also lead to various diseases, but now Zhao Yan told them that some diseases are caused by a small creature called a virus, which completely subverts their worldview.

After getting along with Cao Ying during this period of time, coupled with the understanding of his previous life, Zhao Yan also knew a little about the medical theories of Chinese medicine, and now seeing Cao Yan and Zhilugu's incredible expressions on their faces, he also understood how huge the impact of his words had on them, but he decided to finish the medical theories of the later generations.

I saw Zhao Yan clear his throat and said: "The medical skills I learned are very different from the existing medical skills, in my opinion, there are two main factors for patients to get sick, the first is personal factors, that is, the person's own problems, for example, a person is born blind, this is a congenital cause, or he has not eaten for a long time, this is an acquired cause, both of which are personal factors, and they may also cause physical illness." ”

Speaking of this, Zhao Yan paused for a moment and then said: "In addition to the factors of the sick person himself, there are also environmental factors, such as the virus I just mentioned, which belongs to the biological cause of environmental factors; poisoning, which is a chemical etiology among environmental factors; There are also injuries, which are among the physical causes of environmental factors; Finally, there is a social etiology, which is very complex and cannot be explained for a while. ”

What Zhao Yan said above is the etiological theory of later generations of medicine, including almost all the causes of illness, but Cao Tong and Zhilugu were dumbfounded, the little creature named the virus just now was enough to surprise them, but they didn't expect Zhao Yan to throw out a theory of etiology in a blink of an eye, and what he said was the Tao, even they felt that Zhao Yan didn't seem to be talking nonsense.

Maybe these etiological theories said by Zhao Yan were too amazing, Cao Tong and Zhilugu were silent for a long time after listening to them, and they finally woke up from the shock, but Zhilugu still couldn't fully believe it at this time: "King Jun, what you said seems to be quite reasonable, but it is completely different from the medicine we studied, I don't know if you have any way to prove that these theories of yours are correct?" ”

"Yes, grandson-in-law, these words of yours are so amazing, even me and Brother Zhilu are a little unacceptable, especially your biological cause, I can't believe it, how can there be those invisible little insects in our bodies?" Cao Yan also said at this time, he was now the same as Zhilugu, and he couldn't believe that what Zhao Yan said was true.

Seeing that Zhilugu and Cao Yan asked for evidence from him, Zhao Yan laughed and said: "It's not easy for the two of you to want evidence, you wait a minute, I'll let you see those little creatures that you don't usually see!" (To be continued!)
