Waiting at the door for a long time, watching the pedestrians from the other world coming and going, is also a little fun. I don't know how long I waited before I saw Chen Changsheng walking back in a hurry.

He was still followed by the big man.

Seeing his happy face, Ren Baqian knew that it was done. Knowing that he had saved someone, he was still a little excited in his heart, and he unconsciously had a smile on his face.

"Mr. Ren, it's thanks to you for saving people this time. Chen Zisheng pulled Ren Baqiandao.

"Thank you, thank you, brother. The big man came up with a happy face and gave Ren Baqian a bear hug directly, Ren Baqian heard his bones moan, and he almost couldn't get up in one breath, he finally knew why it was called a bear hug. It's really like being hugged by a bear, and it is directly strangled in the chest, and it is difficult to even breathe.

finally broke free from the big man's arms with the help of Chen Zisheng, and quickly gasped for a long time, and the other party didn't realize that he almost killed his life-saving benefactor, so Ren Baqian really wanted to give him a few kicks.

"I don't have any good things, but this knife is the most valuable thing in my body, so I'll give it to you. The big man untied a half-meter-long short knife from his back and put it in his hand.

"I don't need this thing, you can take it back. I'm very happy to be saved. Ren Baqian hurriedly excused himself and refused.

"How can I do such a grateful, unreciprocated thing? You saved my mother-in-law's life, as long as I can take it, you can take whatever you like. But this knife is my most valuable thing, so I gave it to my brother, which is a thank you. The big man said to Ren Baqian with a serious face, and the joy on his face couldn't be hidden.

"Mr. Ren, you can take it. If you take it, he will not be at ease. Chen Zisheng said with a smile.

"I'll give you something, I'll go back to see my son first. After speaking, the big man turned around and left with a cheerful face.

"Dayao people are like this, Mr. Ren is used to it. Chen Zisheng looked at the back of the big man and said with a smile to Ren Baqian.

Ren Baqian looked at the short knife in his hand, with a sheath of animal skin, and the handle was also wrapped around animal skin. The weight is not light, it is five or six catties.

I've heard Steward Shi say before that Dayao National Iron is still very valuable. Such a knife cannot be afforded by ordinary people for several months without eating or drinking.

But it's really useless to ask for this thing yourself.

Metal weapons are all over the streets of the earth.

Seeing that the big man was in the crowd, Ren Baqian shook his head helplessly, carrying a short knife and Chen Zisheng in.

As soon as Chen Zisheng came back, everyone inside got up and greeted him, "Doctor Chen, Doctor Chen!"

The side verifies that Chen Zisheng's popularity here is indeed very high.

Although Dayao people don't like foreigners, people like Chen Zisheng are respected wherever they go.

What the people of Dayao hated was the greed of foreign merchants, and the condescending attitude of many people who came to Dayao and regarded them as barbarians.

When he arrived at the table where the patient was treated, Chen Zisheng pointed to the wall next to him, where a wooden sign hung with some words on it. Ren Baqian had seen this sign a long time ago, but he didn't know what was written on it.

Seeing that Chen Zisheng deliberately pointed to the sign, Ren Baqian asked, "What is written?"

"It is strictly forbidden to hold the doctor," Chen Zisheng said in a low voice with a worried face.

Ren 8000: ......

It seems that being too loved is also risking your life. As far as Ren Baqian knows, there are not many literate people in Dayao, and it is indeed not easy for Dr. Chen to survive until now.

When the two of them entered the back room, their eyes were fixed on what Ren Baqian was holding.

"What do you think I have here?" said Chen Zisheng dryly.

Not only is this thing life-saving, but it also works extremely well.

"The recipe and raw materials of the black mud paste. "Ren 8000.

Chen Zisheng hesitated, the penicillin that Ren Baqian said last time was also what he wanted very much, and according to the description, there were more people who could be saved.

It's just that it happens from time to time that pregnant women die of postpartum hemorrhage, and every time he encounters it, he feels very sorry, and he sees a young life withering away.

A large number of them are only in their teens, which is even more regrettable.

"I just want the recipe and raw materials of the black mud paste, or as I said last time, I will teach you how to make penicillin. As for these things, I'll give them to you. It means more in your hands than in mine.

However, I would recommend that you give these things to those who are stable and teach them how to use them, so that they don't get too late. Ren Baqian said.

Chen Zisheng turned his head to look at Ren Baqian, tidied up his clothes, and then bowed respectfully.

"I thank you for them. Chen Zisheng said sincerely.

"It's nothing, these things don't have much use in my hands. Ren Baqian shook his head and said. He bought a total of 100 boxes, which is more than 2,000 yuan, plus the needle and catheter are a few hundred yuan more.

This money can't do much on the earth, and he doesn't lack this money now, but here he can save the lives of an unknown number of people.

"Those things, if you want to use them again after using them, you must boil the water and put the things in it to sterilize. It can also be replaced with other things, such as fish bladders or animal bladders, casings, etc. You can look into what is more suitable. Ren Baqian said.

"We will. I will pass on this method so that those stable women know. This is a way to save people, and more people should know about it. Chen Zisheng nodded and said solemnly.

Ren Baqian smiled, this Chen Zisheng is really good.

"Okay, a lot of time has passed today, and I'll leave the production and extraction method of penicillin to you. Ren Baqian said.

Waiting for Chen Zisheng to take out the few moldy fruits, Ren Baqian taught him how to make the culture liquid and then how to filter it.

Most of these procedures were explained by him, and he didn't really do them.

If you do it all, you won't have enough time. And there are things that are also lacking.

You can buy rice, vinegar, and the like. It's just seagrass or alkaline water, and Chen Zisheng needs to figure it out by himself.

Chen Zisheng took a pen and paper to record there, asking a sentence or two from time to time.

After talking about everything, the time was also in the evening, Ren Baqian advised: "Remember, with penicillin, a very small number of people will have allergies." If this happens, it's best to stop taking the medication. ”

Chen Zisheng put down the pen and paper and wrote for an afternoon, and he was tired enough. After listening to Ren Baqian's words, he nodded in understanding. For the same disease, the effect of medication is different for different people, and he will not understand this.

During this period, Ren Baqian probe glanced at the things he remembered, and he didn't know a few books. But one thing can be seen, the handwriting looks like a chicken's paw scratching.

"Who said that the doctor's handwriting is good?" Ren Baqian had this idea at that time.

"That's pretty much it. Ren Baqian stuffed a few other books to Chen Zisheng.

"Of these three books, one is "Miscellaneous Treatises on Typhoid Fever" and the other two are anatomy. They are another medical theory, different from yours, that they don't talk about what they do, they specialize in the anatomy of the human body. You can also refer to it. But you shouldn't be able to understand the words, I don't have time today, and I'll translate it for you next time I'm free. ”

Chen Zisheng carefully took the book, he knew the value of the book, especially this kind of unborn, maybe one of them could solve some of the problems that had been bothering him. There is no limit to the value.

After reading it twice, "Miscellaneous Treatises on Typhoid Fever" is basically full of words, and I can't understand it.

The other two are the structure of the human body, and there are many anatomical drawings in them.

Chen Zisheng looked at it and asked, "How did they study it? How can they draw such a similar picture?"

"I guess it was done with corpses. Ren Baqian said uncertainly. He didn't know much about the development of Western medicine.

"No matter how you research, there is nothing wrong with knowledge. ”

"That's right. Chen Zisheng nodded.

"Then I'll go first, and I'll come back in a few days. "Ren Baqian looked at the sky, he should have gone back a long time ago. I don't know if there is anything wrong with not going back so late, and I don't know if the empress sent someone to find him.
