In the room, Ning Yunxi preached to three college students: "Plastics are divided into many types. You all know about chemical engineering, so I don't need to say much. However, this year, our country has introduced new technologies from Germany and Japan, membrane materials made of acetate fiber and cuproamino fiber."

"I know this. It is used for artificial dialysis, but we only have membranes. Our professors have said that people won't tell us how to make this."

Hearing the students in chemical engineering shouted that Lin Shangxian knew in the hospital that artificial dialysis is extremely important to kidney patients, he had a serious expression. If this thing that concerns people's lives is technically restricted, it is very terrible. No wonder Teacher Ning asked them to come and have a thermoplastic resin. It is obtained by esterification under the action of a catalyst by acetic acid as solvent acetic anhydride as an acetylated agent." Ning Yunxi directly told the students the answer.

Several college students were holding their breath and listening to her talking about the most advanced technology in the world.

Grandma Meng walked to the living room and saw what the two kids did and shouted: "What have you done in your brother's book?"

When Lin Shangxian heard this, he suddenly remembered the book he placed on the table, and hurriedly turned around and walked out to the living room.

On the living room coffee table, I saw that all his anatomy books were opened. Meng Chencheng and Leilei heard his footsteps lifting up to him, showing a pitiful expression: "Brother."

"Oh." Lin Shangxian couldn't help but sigh. Seeing the expressions of these two children, they knew that they were scared by these pictures, so not everyone can study for medical treatment.

Brother, I was so scared~ Leilei ran over and hugged his brother's legs with his little hands on his face.

Lin Shangxian patted the kid's back with his hand: "It's okay, my brother is here. This is a picture, nothing, forget them, Leilei."

But he and his aunt looked at it, and the aunt told him what the intestines in his belly were. The young master was so scared that he couldn't tell the difference between the east, south, west and north. Leilei's little mouth looked somber and cried.

Lin Shangxian picked up the baby and put it on his thigh and comforted him: "It's okay, I'm afraid to think about my brother, okay? I'm here."

At night, the whole family had a meal. Grandma Meng happened to make the braised large intestine.

Meng Chencheng and Leilei's small eyes saw the pig's large intestine, and immediately recalled the picture they saw in the evening.

"Come on, Chencheng, you like it." Grandpa Meng knew that the little girl was very good at eating, so he picked up some for the little girl. This pig intestine is not easy to buy, and it is more expensive than pork. It is something that is not made very much.

Meng Chencheng's hands immediately covered his mouth.

"What's wrong with her?" Grandpa Meng asked in surprise.

Grandpa went out for a walk in the afternoon, so he didn't know what was happening at home. Meng Chencheng stood up and ran to the bathroom. Similarly, Meng Chenjun, who was unaware of the situation, turned his head in surprise and looked at his sister worriedly, "Xiao Wu, are you sick?"

"What's sick?" Grandma Meng said to them, "Today she and Leilei went to search for the book they put on the coffee table by Brother Shangxian, and were frightened by the pictures inside. It was a book read by the doctor, not for them to read. They read it secretly by themselves, deserved it."

Ning Yunxi looked at his son's little white face, who was as miserable as a little girl, and raised his eyebrows: Have you been educated?

I'm so curious. I don't ask the adults, I'll know what the final result will be.
