When the matter was urgent, Li Chengqian quickly left the Taiji Palace, and his methods would be implemented, and now it was important for him to do a good job in the prevention of smallpox.

I have to admire Cheng Biting Jin, and at a critical time, he dispatched troops to block all the passable roads near Lantian County, and laid a net to prohibit some patients from Lantian County from escaping to Chang'an.

This time it started in the barracks, because there were too many cattle to be arranged in the East Palace.

When Li Chengqian arrived at the barracks, Sun Simiao was already there anxiously waiting for his arrival.

"Your Royal Highness the Prince, you are finally here. Xing Guogong had just found a cow with cowpox, which was in the camp. ”

"Sun Zhenren, take me there!"

Li Chengqian knew that he was in a hurry at this time, so he said so.

Sun Simiao was very positive, he opened his legs and quickly rushed to the position he said.

At this time, Fang Xuanling, Du Ruhui and others were there.

"Your Royal Highness the Prince, the ministers are looking for you, you see, this is a cow with cowpox, and I also brought five death row prisoners."

"Just one end?"

If it's just one head, it's not enough.

So Li Chengqian asked.

"There's only one for now, but I'm sure I'll find more in the future! I've sent someone to requisition all the cattle in the vicinity! ”

There are a lot of cows, but there are not many sick ones, and there are a lot of them.

"It's not bad, this king thought it would take another day or two, but now it seems that it is not needed. You're doing a great job! ”

Fang Xuanling knew that Li Chengqian was comforting him, so he said:

"The minister still has done less."

"His Royal Highness the Prince, without further ado, I think we'd better hurry up!"

Sun Simiao was very anxious on the side.

Li Chengqian looked at the side again, and there were five death row inmates lined up, waiting for pox.

How did these five people know what they were going to do, why it was a cow again, and this cow looked a little ...... Scary.

"Sun Zhenren, come over and take a look, is this cow a cowpox!?"

Sun Simiao came over to take a look, then nodded.

"It seems like yes, it's kind of similar to what people look like."

"Then let's get started! Xue Rengui and Su Lie, you two will control this cow! ”

Li Chengqian said so, the two of them understood, Xue Rengui was in charge of the front, and Su Lie was in charge of the back.

Rise......

The two of them exerted force at the same time, and the cow was picked up, and it barked loudly, looking very helpless.

Its cattle have been insulted ever since, and they have been so humiliated by two humans.

However, it has no power to resist at all.

This directly caused the soldiers in the camp to look dumbfounded.

"Sun Zhenren, I'm going to ask you to collect these cowpox!"

Sun Simiao responded: "Let the old man come." ”

Sun Simiao is a doctor, and he is very skilled in this kind of operation, and this is only to collect vaccinia liquid.

Finally, in his skillful technique, he collected some liquids, which could be applied directly to people's wounds for pox.

However, if these liquids are dried and dried into powder, the smallpox virus can be coarsely inactivated, making it less toxic and safer after vaccination.

However, there is no time to do this now.

"What should His Royal Highness the Crown Prince do with these liquids?"

"Inflict on these five people, sow pox!"

Although Li Chengqian's words were light, they made Sun Simiao a little resistant.

At the same time, although these five people were detained by the soldiers, they still shrank their bodies back as much as possible, as if they had encountered a ghost.

"His Royal Highness the Prince, the old man is saving people, not harming people...... Your ......"

As soon as Sun Simiao's words came out, the five people were directly paralyzed by fright, what is harmful, is this thing poisonous?

What if they were to be tested? Because none of them are good, either murderers or Jiangyang thieves, they know what the end will be since they do it.

Therefore, they had nothing to pity, and then said: "Sun Zhenren, you are saving people!" If it is successful, how many people will be saved because of it? Then there will be no such disease as smallpox in the future generations, and we will be the great people in this world. This is merit, and it is in the plate in your hand. ”

Li Chengqian tried his best to persuade Sun Simiao.

But he's a healer, and he's still a little overwhelmed.

"This king guarantees with his life, this thing will not die!"

In the end, Li Chengqian had to say this.

Seeing that Li Chengqian was so determined.

Sun Simiao seemed to be a little relieved in his heart.

"Okay, then the old man will do it!"

At this time, someone handed a knife.

Sun Simiao glued a trace of liquid to the tip of the knife and walked to the first prisoner.

"Sun Simiao, you dare! What a miracle doctor you are! Are you trying to kill someone? ”

Li Chengqian didn't expect that the first person would be so fierce that he opened his mouth to scold Sun Simiao.

They are also called by name.

Li Chengqian gave a look, and Xue Rengui kicked the prisoner in the abdomen.

The guy immediately became honest.

Sun Simiao was still too merciful, but when he thought that a large number of people behind him were being tortured by smallpox, he still took action.

The knife, which was very sharp, cut a small cut directly on the prisoner's arm, and the liquid stuck to it.

As a result, the prisoner, who was already very fierce, collapsed directly on the ground, his eyes full of despair.

"Don't worry, this thing won't kill you! It's just that you're going to have a little life, and you guys are all as strong as oxen, and you'll be fine. The king also tells you that you will never be punished by smallpox again in your life! ”

Li Chengqian tried his best to explain, if he didn't explain, they might be scared to death, and then this pox would be meaningless.

Soon the other four were also on board.

Sun Simiao was asking: "His Royal Highness the Prince, that's it...... Simple? Won't these prisoners be infected in the future? Or got sick and died of smallpox? ”

Li Chengqian really couldn't explain the specific reason, and he wouldn't tell them that it was because people would produce some antibodies or anything like that.

"Don't worry, this king says it's okay, you believe me!"

Li Chengqian said it very confidently, as if it was true.

It also seems to be true.

"That's ...... Okay, so how would these people react? ”

"Sun Zhenren, they have a little reaction at most, and they will be fine, but if you want to study, you can observe one or two."

"Yes! Then these five people will be handed over to the old man to deal with! ”

"Feasible!"

Li Chengqian also lived in the barracks for a few days, and the epidemic was getting worse day by day, and Li Shimin also came to look for him several times, but he couldn't be too anxious to test this kind of thing, so he was persuaded by Li Chengqian to go back.

It wasn't until the fourth day later that Sun Simiao hurriedly came to look for it.

"His Royal Highness the Crown Prince...... That's great! "Take a hundred plating, and read the latest chapter of the "Tang God-level Prince Claw Book House" for free for the first time.
