After waiting at the door for a long time, it was a little fun to watch the pedestrians from other worlds coming and going. I don’t know how long it took to see Chen Changsheng hurried back.

The man was still following him.

Seeing his happy face, Ren Baqian knew that the matter had been done. He knew that his way had saved someone, but he was still a little excited and had a smile on his face.

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

"Brother, thank you, thank you." The big man came up with a happy look and directly gave Ren Baqian a bear hug. Ren Baqian heard his bones moan and almost couldn't get up in one breath. He finally knew why it was called Xiong Hu. It was like being hugged by a bear, and it was difficult for him to breathe.

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

"I have nothing good, just this knife is the most valuable thing on my body, so I'll give it to you." The big man took off a short knife half a meter long from his back and put it in his hand.

"I don't need this thing, you can take it back. I'll be very happy if I can save it." Ren Baqian quickly refused.

"How could I, Da Yaoren, do such a thing that I can't repay you? You saved my wife's life. As long as I can take it out, you can take whatever you like. But this knife is my most valuable thing, so I'll give it to my brother, which is a thank you." The big man looked serious and could not hide the joy on his face.

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

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

"It's all like this for Da Yao people. Just use Mr. Ren to get used to it." Chen Zisheng said with a smile to Ren Baqian as he looked at the back of the man.

Ren Baqian looked at the short knife at hand, with a skin scabbard, and the handle of the knife was wrapped in the skin. The weight was not light, it was enough to be five or six pounds.

I heard from Manager Shi before that the Dayao Kingdom ironware is still very valuable. Such a knife can't be afforded if ordinary people don't eat or drink for several months.

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

Metal weapons are valuable in Da Yao, and the streets are everywhere on the earth.

Seeing that the big man was hiking in the crowd, Ren Baqiancai had no choice but to shake his head helplessly, and walked in with Chen Zisheng with a short knife.

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

This indirectly verifies that Chen Zisheng's popularity here is indeed very high.

Although Da Yaoren does not like foreigners, people like Chen Zisheng are respected everywhere they go.

What Da Yaoren hates is the greed of foreign merchants and the noble attitude of many people who regard Da Yao as a barbarian after coming to Da Yao.

When he arrived at the table to treat the patient, Chen Zisheng pointed to the wall next to it, where there was a wooden sign hanging with some words on it. Ren Baqian had seen this sign for a long time, but he had never known what was written on it.

Seeing Chen Zisheng pointing at the sign specifically, Ren Baqian asked, "What are you writing?"

"It is strictly forbidden to hug doctors," Chen Zisheng whispered with a grievance.

Ren Baqian:...

It seems that being too loved is risking his life. As far as Ren Baqian knows, there are not many people who know Da Yao, and it is indeed not easy for Dr. Chen to survive until now.

When the two entered the inner room, their eyes were placed on the thing Ren Baqian was holding and stopped moving.

"Look at what I have here?" Chen Zisheng said simply.

This thing not only saves life, but also has excellent results.

"The formula and raw materials of black mud paste." Ren Baqiandao.

Chen Zisheng hesitated for a moment. The penicillin that Ren Baqian mentioned last time was also what he wanted very much, and according to the description, there were more people who could save them.

However, it is also common for pregnant women to suffer heavy bleeding after childbirth. Every time they encounter it, it makes him feel very regretful. Seeing young lives withering.

A large part of them are only in their teens, which makes people feel even more regretful.

"I just need the formula and ingredients of black mud cream. As I said last time, I will teach you how to make penicillin. As for these things, I will give them to you. It means more in your hands than in my hands.

But I suggest you distribute these things to those who are busy and teach them how to use them so as not to have too late.” Ren Baqian said.

Chen Zisheng turned around and looked at Ren Baqian, tidied up his clothes, and then bowed respectfully.

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

"Nothing, these things are not very useful in my hands." Ren Baqian shook his head. He bought a total of 100 boxes, which is more than 2,000 yuan, and the syringe and fluid catheter are only a few hundred yuan more.

This money can't do anything on Earth. He is not short of this money now, but he can save countless lives here.

"If you want to use those things again after using them, you must boil the water and put the things in it to disinfect. You can also use other things instead, such as fish bladder, animal bladder, casing, etc. You can study what is more suitable for using." Ren Baqian reminded him.

"We know. I will spread this method so that all the stable ladies can know. This is a way to save people, and more people should know it." Chen Zisheng nodded and said solemnly.

Ren Baqian smiled. Chen Zisheng is indeed a good person.

"Okay, there is a lot of time today. I will give you the method of producing and extracting penicillin." Ren Baqian said.

Waiting for Chen Zisheng to take out the fruits covered with mold, Ren Baqian taught him how to make culture medium and then how to filter it.

Most of the procedures were explained with things and did not really do it.

If you do the full set, you will definitely not have enough time. And some things are also lacking.

You can buy rice, vinegar, etc. It is just seaweed or alkaline water, so Chen Zisheng needs to find a way out by himself.

Chen Zisheng took a pen and recorded it, asking questions from time to time.

After finishing everything, it was time tonight. Ren Baqian reminded: "Remember, if penicillin is used, a very small number of people will suffer from allergies. If this happens, it is best to stop taking the medicine."

Chen Zisheng put down the paper and pen and wrote for an afternoon. He was very tired. After listening to Ren Baqian's words, he nodded to show that he understood. The effects of medication for different people are also different for the same disease, and he will not misunderstand this.

During this period, Ren Baqian looked at what he remembered, but he didn't recognize any of them. However, one could tell that the handwriting seemed to be scratched by a chicken's claws.

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

"Basics are all." Ren Baqian sent several other books to Chen Zisheng.

"These three books, one is "Miscellaneous Treatise on Typhoid Diseases", and the other two are anatomical. They are another medical theory, which is different from your medical skills. They do not talk about looking, listening, asking and touching, and specialize in the structure of the human body. You can also refer to it. However, you should not understand the words. You have no time today. I will translate it for you when I have time next time."

Chen Zisheng carefully took the book over. He knew the value of the book, especially such unrealized ones. Perhaps one of them could solve some problems that have always troubled him. The value is difficult to limit.

After reading it twice, the "Miscellaneous Treatise on Typhoid Diseases" is basically full of words and cannot be understood.

The other two are structures of the human body, including many anatomical pictures.

Chen Zisheng looked through and asked, "How did they study it? How could they draw so similar?"

"It should be studied using corpses." Ren Baqian said uncertainly. He had no idea about the development of Western medicine.

“No matter how you study it, there is always nothing wrong with knowledge.”

"That's true." Chen Zisheng nodded.
