Chu Fei smiles. It seems that he is right. Later, he exchanged a box of penicillin on the system interface. Of course, in the old man's view, Chu Fei just casually appeared in Chu Fei's hand.

This penicillin is packaged in cartons with plastic protection inside. Penicillin itself is packaged in small glass bottles, which are the kind of small glass bottles that can be seen when injection is given in hospital clinics.

The size of the bottle is like a person's little finger. The neck of the bottle is very thin and long. When you use it, you can break the neck of the bottle with anything, and then use a syringe to suck out the liquid medicine inside and inject it into the person's body.

This kind of thing is common on earth, but in this world, it should be a gamble.

"What's this?" The old man looked at the paper box in chufei's hand.

In fact, Chu Fei thought that there would be a brand name on the carton package of this thing. As a result, after he really held it in his hand, he realized that the outer package was just a pure white carton, without any words and pictures printed.

"If I expect it to be right, it will cure the father's illness."

"Here? Really? " Because the package has not been opened, so the old man did not see the contents, so he would not be surprised by the fresh carton package.

"It's not an elixir. What can be cured is just a slightly special mortal disease, and it's also the one I want to trade with you..."

"Can I have a look first?" The old man wanted to understand that although the young man in front of him said it well, he still had two ways to say whether it would work or not.

Chu Fei shrugged his shoulders and put the carton on the table, letting the old man check it. Chu Fei knew that the old man must have wanted to judge whether the penicillin he took out had any effect by relying on his years of medical experience.

But the problem is, it's not Chinese herbal medicine, and it doesn't have the appearance of Chinese herbal medicine. This thing can only be extracted after a lot of complicated processes, where ordinary people can see it with their eyes.

The old man carefully picked up the carton from the table, and then looked for a long time to determine where the carton was opened.

"This Young master, what is this

The old man had already taken penicillin in his hand. He was very surprised at the glass bottle with such smooth surface and special shape. However, what made him more concerned was that it seemed that it was only water.

Fortunately, the old man was not an impulsive young man. Although he was puzzled, he believed that the young man in front of him could give him an explanation.

"Is this a vessel made of crystal?"

Crystal is a common material for many jewelry, but the price of crystal is not expensive. Compared with other gems, the production of crystal is relatively easy.

"Is the old man still interested in crystal?" Chufei doesn't want to tell the old man that it's glass, and it's made from oil. Because he worried that in this way, the old man would want to know how the oil came from.

Therefore, Chu Fei neither affirmed nor denied, but along the old man's words to open the topic.

"Ha ha..." The old man was also smart and said with a smile:

"originally, I thought you were just bluffing me with clean water. Until I noticed that the crystal vessel was so exquisite, I withdrew that idea. After all, it is enough to prove the master's ability to make such exquisite crystal vessels. "

Chu Fei shrugged his shoulders and said:

"old man, I'll make it clear that I want to exchange this for your nine dead soul. Of course, I want other good things. It's going to work before I make a deal. So, I'd like to trouble the old man to take me to the rich man's house. Let's use his father to test the effect of this medicine What do you think? "

After hearing this, the old man was stunned. He didn't seem to think that Chu Fei would take the initiative to make such a request. This is a rare behavior in his decades of medical practice.

"Well, I mean it. In this way, let's go. I hope my old friend can really turn the corner."

Chu Fei raised his eyelids, he recognized the meaning of this, but he did not ask more.

Later, the old man went downstairs with Chu Fei, explained to a middle-aged man in charge, and then led Chu Fei out of Tongrentang.

Considering the size of Heixia Town, Chu Fei speculated that since it could be used to walk, it meant that the place to go was not far away. Otherwise, it will be more convenient to ride on horseback.

Sure enough, this journey took about five or six minutes. Chu Fei followed the old man down the road to the south to a crossroads, then turned a corner and came to the gate of a mansion.

Standing in front of the door, Chu Fei knew that this family was a real rich family. The word "rich" often appears everywhere.

But being rich and being expensive are actually two different things. Why some people are regarded as local tyrants while others are regarded as rich families? Here is the difference.

In front of this big stockade, there are several old numbers on both sides of the gate. Each of them is towering and thick. It is estimated that it will never look like this in a hundred years. In front of the door, there is a stone for the upper horse and a stone for the lower horse. A pile of stones is left and right.When Chu Fei looked at the house, the old man had already stepped up the high steps. At this time, a man was walking out of the side door. His clothes were gorgeous.

"Oh, Mr. Xue, you Are you here to see our master off for the last time? " This man is in his forties. It seems that he should be a housekeeper or something.

"Ye Li, how are you?" The old man didn't answer the man's question, but asked a question about the patient.

"Well, you're at a loss. I'm going out to prepare the coffin robe..."

The sadness on Ye Li's face was hard to hide, which showed that he was very loyal to the owner of the disease.

"Well, you go and tell me. I'll invite a young man to save your master's life."

"Ah? Really? I Well, forgive me This Ye Li hesitated for a moment. After all, the person the old man "invited" was Chu Fei. Chu Fei's age didn't seem so convincing.

However, since the old man said that, it would not be a lie, so Ye Li called a pardon and ran back. Running and shouting.

"Come in with me, young master. Human life is of vital importance. Let them make up for this matter later..."

Chu Fei nodded. He didn't adapt to the complicated ancient rites. Now it's very good.

After walking into this mansion, Chu Fei had a deeper understanding of what style the ancient rich were. Is it better to have a villa on earth? But compared with the Ye family, it's no different from ordinary people.

There are five yards in the courtyard, that is to say, there are five yards in front and back. The area of each courtyard can be compared with that of chufei's villa.

When they arrived at the entrance of the first courtyard and the second courtyard, the people of the Ye family came to a large group. In front of him was the young man he had seen in Tongrentang before. Next to him was Ye Li, the middle-aged housekeeper who had run in to report the news. There was a mess behind him, including men, women, old and young.

Chu Fei secretly shook his head in his heart. This kind of formation is really not used to. Fortunately, there was an old man in front of him. Otherwise, Chu Fei really didn't know how to face it.

In fact, it's no wonder that Chu Fei, after all, is a modern man of the earth. If it's facing a group of reporters, fans and beauties, Chu Fei is not afraid, Chu Fei is used to it, but it's not the same thing to face a group of servants.

The patient was in the master bedroom of the third courtyard, and they didn't waste too much time outside, so they came here directly. Now Chu Fei has no mind to appreciate other people's home decoration. After all, there are patients lying on the bed.

At this time, there were more than ten people in the room, which made Chu Fei speechless.

"Let's go out first. It's too messy."

Before anyone else said anything, young master Ye began to blow people. Originally, all the housekeepers could stay, but chufei finally let them go out together.

After all, what you want to use is not suitable for so many people to know. Even if it may be popularized in the world in the future, it is the future.

Mr. Xue of Tongrentang was still holding the box of penicillin that Chu Fei had taken out before. Seeing that all irrelevant people had gone out, he said:

"young master, please..."

Chu Fei nodded and came to the bedside. He first looked at the old man's face and then touched his forehead to confirm whether he had a fever. Later, he turned the patient's eyelids and looked at the coating of his tongue

Then Chu Fei said, "where is the wound?"

"On the chest..." Next to him, Mr. Xue motioned for Mr. Ye to come up to help. He opened his father's quilt and untied his clothes, revealing the wound wrapped with gauze bandage.

Chu Fei glanced and found that there was no blood on the bandage gauze. It seemed that he was very diligent in changing it. But that's not enough, so chufei asked master ye to cut off the bandage.

After the bandage was cut, the frightening wound was completely presented in front of chufei's eyes. The wound is very long, but not very deep. As Mr. Xue said before, there is a lot of pus and blood on the surface of the wound, which is really a symptom of sepsis.

"I don't think anyone can use this medicine. After all, people are different. Some people use it and it works. Some people use it but die faster... "

Chu Fei didn't study medicine, so even though he knew penicillin needed skin test first, the problem was that he couldn't. Although it is not impossible to learn from others, he is not professional after all. He is clumsy and easy to see the problem.

Next to him, doctor Xue and master Ye nodded, and they agreed with chufei. This world is a world where immortals can be cultivated. Naturally, we know that different people have different constitutions and attributes.

"Don't worry, young master. If you don't come, my old friend will have to die."
