When Shi Lao heard it, he laughed.

"You touch it first, how does that feel?"

Chu Nan touched it with his hands and found that it felt very good, similar to the feeling of touching people's normal skin. However, Chu Nan touched it carefully and felt that it was a little different.

"Master, it really seems to be a human face, but if you feel it carefully, it doesn't seem to be like it."

"If you touch your face, you won't know what to do?"

When Chu Nan carefully felt his face with his hand, and then stroked the human skin mask, he found that the feeling was really different.

"It's different."

"Nature is different. The skin of a person, although good, will soon become dry if it is peeled off, which is completely different from the ones you read in martial arts novels or even movies. There may be those, but most people probably don't use it that way. Now you see this, the material that makes the human skin mask comes from the membrane inside the cow. ”

"The membrane of the cow?"

Hearing a lot of human skin masks made of human skin peeled off people's bodies, Chu Nan was a lot more relieved. But what kind of membrane does the cow have, he really doesn't know the way?

For he usually saw few live cows, but as for beef, he had eaten it.

"Seeing that you grew up in the city, you may not even see a live cow, let alone know the structure of a cow. If you have time, you can go to the slaughterhouse and see how those butchers are separating after killing their cattle. ”

Of course, the whole body of the cow is a treasure, many people know it, especially the bezoar, which is taken from the cow, and some bezoars are more expensive than gold.

"It's good."

"Let's not talk about cows, let's talk about pork. Pork is divided into fat and lean meat, and often the fat and lean meat of pigs are almost a lot, have you ever seen the white and thin layer of things stuck to the lean meat. ”

"Master, I've seen it."

"Yes, the membrane I'm talking about is those things, and cows are different, most of them are lean meat, and that membrane is the ones that stick to your lean meat, those things, usually those butchers will peel off with knives. But for us it's different. ”

"Master, who are you to make the human skin mask from, and what membranes do you come from?"

"Not bad."

Hearing this, Chu Nan got to know a lot more.

When I heard Master's words just now, I almost had a crooked idea, and I thought that the membrane of the cow came from NB.

"As long as those membranes are collected, and then they are treated with special colors, and other treatments, and at the end of the day, they become a thin mask of human skin."

Because those membranes come from cows. Therefore, Chu Nan no longer had the feeling just now, and when he touched it, he found that it was really different.

Of course, there is no smell of beef, no other miscellaneous smells, and the color looks exactly the same as the yellowed skin of the human body.

"The colors of blacks and whites can be imitated as well. However, this is only the most important part of the human skin mask. Other parts, such as the nose, eyes, ears, lips, and even the mouth and hair, have to be changed. Actually, it's easy to change just part of it. However, if it is really fundamentally a person, then all parts of the human skin mask on that face must be well matched without revealing the slightest flaw. ”

"Since you want to learn human skin masks, you have to start with the most basic materials for making human skin masks." ……

Chu Nan and Shi Lao talked a lot inside, because they were hungry, and when they went outside, Jin Xudong also came back to make lunch.

Chu Nan had dinner with Shi Lao, Jin Xudong, and Yang Anping, who had a better face.

Whether it is a tough guy or someone else, they may need to talk about it, but now, when Yang Anping told him about his things and no longer had to press them in his heart as before, he felt a lot more comfortable.

After Chu Nan finished eating, he looked at the time and found that it was almost twelve o'clock, so he looked at Shi Lao and the two and said.

"Master, I'll come back to learn from you tonight, I'm going back to class."

Chu Nan hurriedly ran out of the city, got into the car, and went back in the direction of Jinda.

Unexpectedly, after talking to Yang Anping, and when he began to learn the disguise technique with Shi Lao, it took so long, and now that he returns to Jinda, he must be late again.

So, call Zhu Junhui's side.

"Junhui, help me ask for leave, I may be late."

"That's good, squad leader."

When Chu Nan was driving, he didn't speed, let alone run the red light, and when he returned to Jinda, half an hour had passed before the start of class. He walked up to the classroom, up to his own classroom, and found that it was still the professor.

Chu Nan stood there and said.

"Report."

"Why are you again? You can't oversleep again, right? ”

Last time, it was Chu Nan who was late, and this time it was him again.

"Professor, I have some personal business to do, and I'm half an hour late."

The professor didn't say anything more, because a classmate had already asked for leave for Chu Nan just now. Of course, Zhu Junhui took sick leave for Chu Nan, and now he is here.

"Squad leader, I asked for sick leave for you, and you're here now."

Zhu Junhui whispered.

"It's fine."

Although Chu Nan was driving back and forth, he didn't feel any fatigue. Sitting there, he took out the history book and directly recalled the words that Shi Lao said to him.

As for what kind of historical knowledge the professor on the stage in front of him said, Chu Nan didn't care too much.

Because it's all in the textbook, even if the key points are marked before the exam, they are marked out in the textbook.

After the professor left after taking two classes in a row, Chu Nan found that there were the third and fourth classes in the afternoon, as well as the public course "College English", so he could only walk towards the large classroom of the public class with Zhu Junhui.

"Class leader, you won't take care of that senior sister again, will you?"

Zhu Junhui asked.

"Of course not, Senior Sister Liu is almost fine, so I don't need to take care of it." ……

When they came to the classroom, the three of them sat in the back row, and Tang Xueru and Li Wenlan, who were sitting in the front, still looked at Chu Nan strangely. Especially these days, Chu Nan has asked for leave one after another, and he doesn't know what he does.

And what is even more strange to Chu Nan is Wang Yi, since she "kindly reminded" Liu Ruoxue that day, she found that Chu Nan and Liu Ruoxue did not go to the library, and she didn't know what happened to these two people?

Now, when I saw Chu Nan sitting in the back row, I thought that I had succeeded.

When she saw Tang Xueru and Li Wenlan sitting there, Wang Yi looked at her classmates sitting next to Li Wenlan and said.

"Classmates, let's swap seats with each other."

When they saw Wang Yi coming over again, Tang Xueru and Li Wenlan both glanced at each other, wondering what this woman wanted to do?

"Ask Lan."

"I don't know what's going on in the road?"
