As soon as Wang Xiang entered the Taiji Palace, he heard the words of Li Er and Sun Simiao.

"I'll go with you."

After saying it again, Li Er reacted, and looked up at the door violently, the young man standing at the door was much more mature than half a year ago, less uninhibited and a little more stable, and at this time, his eyebrows were even more serious and dignified.

The ministers in the main hall also noticed Wang Xiang and the eldest grandson Wuji.

Li Shimin was first happy when he saw Wang Xiang, and then frowned and said, "No, smallpox is too dangerous, if it is infected......"

The eldest grandson Wuji spoke: "Your Majesty, the prince has a new way to solve the danger of smallpox. ”

In a word, everyone in the Taiji Hall was stunned.

Li Shimin was the first to react, walked quickly to Wang Xiang and grabbed his arm, stared at his eyes with burning eyes and asked, "Do you really have a way to cure smallpox?" ”

Li Shimin's strength was very strong, and Wang Xiang's arm that he grabbed hurt.

Li Zhi and Li Chengqian had an accident, Li Shimin's mood Wang Xiang understood very much, shook his head and said, "I can't cure smallpox." ”

He was telling the truth, smallpox was an extremely terrible virus, and even if it was contracted in later generations, it was incurable, and the mortality rate was extremely high. The virus has been completely eradicated in later generations, and only a very small number of smallpox viruses have been left for research.

Hearing Wang Xiang say that smallpox could not be cured, Li Shimin's expression darkened, and what Wei Zheng said also understood in his heart that miracle doctors like Hua Tuo and Bian Que had no way to do anything with smallpox, but he was unwilling!

Originally, when he heard the eldest grandson Wuji say that Wang Xiang had a way, he was still lucky, after all, Wang Xiang once used the magical blood transfusion method to revive Cheng Chuliang, and also took out a pill that could treat the queen's qi disease, even Sun Simiao was amazed at him, but Wang Xiang's words broke his last glimmer of hope.

"But I have a way to save people from smallpox."

Li Shimin, who was already disappointed, became excited when he heard this.

Wang Xiang said to Sun Simiao: "I will go to Xishui Village with you, but not now. Wait until we vaccinate cowpox first. ”

Hearing Wang Xiang say that it could save people from smallpox infection, the ministers in the hall couldn't help but step forward, and Li Shimin didn't stop them, after all, this matter was too important.

"What is cowpox? What does it have to do with being protected from smallpox? After all, Sun Simiao is a doctor, and he asked the key to the problem in one bite.

"Yes, Zixin, I've only heard of soybeans, mung beans, and what potatoes you made. Cowpox is unheard of, could it be that cows will grow beans? ”

Cheng Biting Jin is this character, seeing him, let's talk non-stop Li Shimin shouted lightly: "Biting Jin, listen to Zixin!" ”

"Yes, yes, he said, hehe." Cheng Yanjin scratched his head embarrassedly, and saw that Li Shimin's mood was stable, and he quietly breathed a sigh of relief in his heart.

Don't look at Cheng Biting Jin's usual grinning, in fact, he is not without thoughts, Li Shimin's mood has been very unstable in the past few days. It seems that he will get out of control at any time, and the generals who were born and died with him are very worried about him.

At this time, seeing that Li Shimin's mood had stabilized, Cheng Biting Jin naturally would not continue to gag, shut up and stood aside, Qin Qiong and Li Jing on his side both nodded slightly towards Cheng Biting Jin.

Li Shimin, who was too concerned about smallpox, didn't notice the small actions of Cheng Biting Jin and Qin Qiong and others, but Wang Xiang noticed it, and sighed at their feelings of monarchs and ministers, Li Er was able to achieve today's achievements not without reason, and the original crown prince Li Jian was far inferior to Li Shimin in this regard.

Everyone looked at Wang Xiang with curiosity. Wang Xiang said: "Smallpox is actually a pox virus, and pox viruses are very contagious. Smallpox is the virus with the highest lethal rate, and although the poxvirus is highly contagious, it has one characteristic. ”

"What are the characteristics?" Li Shimin couldn't help frowning when he heard that the lethality rate was the highest.

"It's that people who have been infected with poxviruses will never be infected with poxviruses again for the rest of their lives."

Sun Simiao nodded thoughtfully: "People who suffer from smallpox and do not die have indeed heard of smallpox infection, but smallpox rarely happens, and I am afraid that it will not be accurate." ”

Wang Xiang said in an affirmative tone: "I can guarantee this!" ”

Sun Simiao and Li Shimin looked at Wang Xiang in surprise, but neither doubted what he said.

"People who have suffered from smallpox will not be infected by smallpox, but they can't be infected with smallpox first......" Cheng Yanjin couldn't help but interject again, but this time Li Shimin didn't drink him, because he also had the same doubts. In this way, the so-called solution is a dead end.

However, Sun Simiao's eyes lit up suddenly when he heard Cheng Yanjin's words, looked at Wang Xiang and said: "You said that smallpox is a pox virus, and people who have suffered from pox virus will never be infected with pox virus again in their lives, and the cowpox you said is also a pox virus?" ”

Wang Xiang glanced at Sun Simiao unexpectedly, he deserved to be a miracle doctor-level cow. The crux of the matter came to mind at once.

"Yes, smallpox is the most lethal poxvirus, but cowpox is a non-lethal poxvirus."

Li Shimin also reacted and asked, "You mean that people will suffer from cowpox first, and then they will not be infected by smallpox?" ”

Wang Xiang nodded, Li Shimin's face finally looked better, as long as people can be protected from smallpox infection, then smallpox will no longer be so terrible.

"But where did this cowpox come from?" After all, no one has ever heard of cowpox.

"Your Majesty can send someone to look for the houses of the people who have cows nearby, and the small white pus that appears near the cow's milk is the cowpox, and the cowpox virus is inside, take the pus from the cowpox, and then cut a small wound on the person's body and wipe the pus on the wound."

Wang Xiang said it easily, and everyone was already numb when they heard it.

Smallpox patients are also pustules all over the body, and everyone avoids them, Wang Xiang actually wants to smear these disgusting pustules on his body......

Wang Xiang smiled bitterly when he saw everyone's expressions, this is no way, although it is a little unacceptable to wipe pus on the wound, but with the current level of medicine, it can only use this simplest and most direct method. Although there were a lot of medicines in the warehouse, there was no cowpox vaccine, which had been injected when everyone was still a child, so he didn't want to prepare this kind of thing at all.

Li Shimin's face was also a little ugly, but he still decisively ordered to send people to collect cowpox in the people's homes, disgusting is nothing, if the people of the Tang Dynasty can be protected from smallpox infection, Wang Zixin will make a great contribution!

The matter of cowpox was arranged by the eldest grandson Wuji, Li Shimin looked at Wang Xiang with complicated eyes and asked in a deep voice: "Is smallpox really incurable?" ”

The emperor of the strongest empire in the world has always felt strong, domineering, even in the face of thousands of troops, corpses, mountains and mountains of blood, he can talk and laugh freely, but now, for the first time, Wang Xiang saw helplessness and even ...... in Li Shimin's eyes Beg.

Wang Xiang's heart trembled, thinking of Xiao Lori, who was also suffering from smallpox, and said gloomily: "There is nothing the minister can do." "In later generations, the level of medicine was so advanced, and there was no way to deal with the smallpox virus, what could he do......

Li Shimin closed his eyes with a sad face, and Wang Xiang still saw a trace of crystal in his eyes.

"Your Majesty, don't be too desperate, although the fatality rate of smallpox is high, it is only three out of ten, I believe that the crown prince and the king of Jin will definitely be able to survive!" He wasn't comforting himself by saying this.

Li Shimin, who was already desperate, opened his eyes violently when he heard this: "What you said is true? Three out of ten dead? (To be continued......)
