"Feifei..." Qin Fei was also a little worried. Her sister was still young and didn't understand anything. She couldn't help but say, "We are girls. We should keep a distance from boys. We can't let our hands be touched casually, otherwise we will get pregnant."

Qin Hongfei didn't do anything when she heard it, but she saw the young man quickly retract his hand in fear and looked at her in horror.

She was speechless, brother, are you serious?

Tang Jinnan raised his eyebrows slightly, but he didn't doubt that the education he had learned from childhood to adulthood was fake. He just felt that Qin Fei used this reason to fool Qin Hongfei, which was a bit of a disdain for her sister.

He sneered, "Idiot."

Qin Hongfei also looked at Qin Fei with a sigh.

Holding hands will get you pregnant?

Do you think I'm a three-year-old child?

Men and women will get pregnant if they don't take off their clothes and go to bed.

"Sister, don't say such ridiculous things in the future." Qin Hongfei said, "Pregnancy requires the combination of sperm and egg. If you can get pregnant by holding hands, the world's population would have been so large that coercive measures would have to be taken to prevent fertility."

Qin Fei was stunned, "Is that so?"

Although she had studied until junior high school, this era and in small cities, this knowledge was not very popular, and the teachers were also implicit.

Qin Hongfei thought about it, nodded and said, "Yes, after the sperm and egg combine, they will form sperm and egg, which will implant in the uterus and develop into an embryo. This is the process of pregnancy, and there is a chance of developing into twins, but the survival rate of twins is lower than that of single babies..." She paused, she had forgotten some of this knowledge, and looked at Tang Jinnan.

Receiving her eyes, Tang Jinnan felt that considering Qin Hongfei's age, she knew too much. Facing several pairs of curious eyes, "Twins are prone to uneven absorption of nutrients. During the embryonic development process, one of them may absorb the other for nutrients..."

This is beyond the normal curriculum.

Everyone was horrified when they heard such a statement for the first time, "Doesn't that mean one killed the other?"

Tang Jinnan said it was not the case, "It's just the embryo. If you don't do this, both may not survive. From a clinical point of view, a six-month-old baby can be said to have his own life."

Two people, one talked about conception lightly.

The other explained what happened after pregnancy.

Qin Yun was a little embarrassed to listen at first, but seeing that the two of them were calmer than each other, as if they were not talking about anything embarrassing but just talking about how nice the weather was, she just listened.

Li Xin was different. When she heard about pregnancy and childbirth, her face turned red with shame. She retreated to the door and looked at them with contempt. She felt that she had become dirty after hearing all this.

Qin Hongfei noticed her eyes and didn't take it seriously at all.

She was popularized with knowledge as soon as she passed through, but the other party was too lazy to say more. She was still holding a notebook and taking notes of knowledge points behind her. She blushed and said, "I'm embarrassed. What's there to be embarrassed about? The Qing Dynasty has been destroyed for many years. If you want to have some fun with the sheets, you still need to study many different ways.

" "Are you going a little too far?" The young man was a little confused! He couldn't help but interrupt and asked.

What's going on?

Were we talking about repairing computers? How did it develop into holding hands and getting pregnant, and then into explaining pregnancy? If we continue talking about this, how are you going to raise the baby?

Qin Hongfei also reflected on himself. He thought that he had gone too far. Who started it? Never mind. It didn't matter. "Have you asked someone else to repair it?"

The young man said with a gloomy face. "I've tried everything. I've asked other engineers to take a look, but it's useless." His father was almost dying of anxiety.

Qin Hongfei thought for a while and said, "Recovering data is very simple, simpler than repairing a computer. I usually don't take this kind of work." If he charges too much, it feels like he's cheating people. If he doesn't charge, it feels like he's wasting his time.
