"Ah?" Su Beibei blushed.
"I don't have enough knowledge in biology, especially the structure of the female human body, so I still need your guidance." Lei Sheng said again.
"It's okay, I'm not afraid of hard work, I, I'm ready." Su Beibei said with her ears turning red.
"Aren't you afraid of hard work, even if it hurts?" Lei Sheng asked.
"Ah?" Su Beibei blushed and said nothing, then said: "Afraid."
"I would like to ask first about the principle of human body temperature circulation?" Lei Sheng stepped forward at this time and pushed Su Beibei against the wall.
"The mutual transmission of body temperature is a knowledge of physics, right?" Su Beibei said: "When objects with high temperature come into contact with each other, their temperature will flow to the object with low temperature."
"So that's it. I've learned." Lei Sheng asked, "So between the two of us, who has the higher temperature and who has the lower temperature?"
"You go ahead." Su Beibei blushed and lowered her head: "Because men usually have more muscles and less fat than women. Since muscles are easier to generate heat than fat, men's body temperature may be slightly higher than that of women. high."
"So professional." Lei Sheng said, "You are so powerful. No wonder others say knowledge is power."
"It's okay." Su Beibei said, "You are the most powerful. In the apocalypse, you are the only one who can walk freely."
"But I can't escape your charm." Lei Sheng said with a smile.
"No way." Su Beibei said shyly.
"But I still don't understand it clearly. As the saying goes, practice is the only criterion for testing truth." Lei Sheng said, one hand slowly stretched out to her waist, and then he hugged her completely Li: "So, for the sake of truth, let's hug each other first."
"Yeah." Su Beibei said.
Their skins touched each other through their clothes.
"Now that the problem of body temperature transmission has been explained, let me ask you again about the problem of oral structure?" Lei Sheng said again: "Can you explain it to me?"
"Of course." Su Beibei pushed up the glasses on the bridge of her nose, opened her delicate mouth, and exposed her pink tongue. She stuck out her tongue and opened her mouth for Lei Sheng to see.
At the same time, she said: "The structure of the human oral cavity is relatively complex, consisting of lips, cheeks, palate, tongue, teeth and oral glands..."
"Let me take a look." Lei Sheng stepped forward and took a look.
“The lips are the front wall of the mouth and can be divided into upper and lower lips.”
After Su Beibei finished speaking, she opened her lips again and said, "It has functions such as protecting the mouth, eating, and kissing."
"What function did you say?"
Lei Sheng asked: "Can you say it again?"
"It has the ability to protect its mouth and eat..." Su Beibei said.
"I said another one." But Lei Sheng had already interrupted her.
"Ah?" Su Beibei's ears turned red.
"I want to try this function." Lei Sheng approached her again.
"Okay." Su Beibei also closed her eyes.
after awhile.
Su Beibei continued to spread knowledge.
"The tongue is an important organ in the mouth. It not only helps us chew and swallow."
Su Beibei said: "It also allows us to taste the sour, sweet, bitter and salty taste. The other is the oral glands, which is the general name for various glands in the mouth..."
"Amazing."
Lei Sheng said: "Then what is its function?"
"The function is."
Su Beibei opened her mouth, moved her tongue around in it, and said, "Taste the taste of the food that goes into it."
"Understood."
Lei Sheng nodded: "Beibei, your mouth and tongue are so beautiful. If you put something into it, can you taste its taste?"
"Ah?" Su Beibei said shyly, "You, if you want, I can do it."
"Then I'll stuff it." Lei Sheng reached out and took out a piece of bread from the bag, stuffed it into Su Beibei's mouth, and said with a smile: "Okay, you can taste it. How does it taste?"
"Ah? This?" Su Beibei was stunned.
She thought Lei Sheng was trying to make a fool of herself, but she didn't expect that Lei Sheng stuffed a piece of real bread into her mouth.
"Fool." Lei Sheng touched Su Beibei's head and said, "I know you are hungry, how could I do anything else with you now? No matter what, I want you to eat before I do anything."
"Thank you." Su Beibei was not polite and ate the bread in her mouth.
Lei Sheng lazily picked up Su Beibei and walked to the sofa in the living room of Su Beibei's house to sit down.
"I still want to ask a question." Lei Sheng's fingers traced the skin of Su Beibei's long legs and asked: "Why is girls' skin always smoother than boys'?"
"Of course it's because of estrogen." Su Beibei said while eating: "Boys secrete male hormones, and their pores will be rough, and of course the whole person will become more powerful. The opposite is true for girls. "
"I see." Lei Sheng nodded: "Being with you really helps me gain knowledge."
"If you don't understand anything, you can ask me." Su Beibei said, "I will tell you everything I know."
"Well, then I want to ask, a handsome young man is holding an intellectual and beautiful young woman wearing glasses who is eating bread. Next, what should the former do to make the latter pregnant with his child? How about giving birth to new life?" Lei Sheng asked seriously with an innocent look on his face: "What about then making a great contribution to the continuation of human civilization?"
"Ah?" Su Beibei was speechless, then blushed and said: "This... we need to combine male DNA with female DNA, and then..."
"Practice is the only criterion for testing truth." Lei Sheng nodded: "In this case, let's stop talking nonsense. For the sake of truth, Beibei, let's practice it."
"Okay." Su Beibei nodded. She had finished eating the bread in her hand and had gained some strength.
"Of course, let's take a shower first." Lei Sheng carried Su Beibei to the bathroom and continued to ask, "I must have been sweating before."
"I'll help you wash it." Su Beibei also took the initiative to say.
"Isn't this bad? But for the sake of truth, let's settle it." Lei Sheng said.
"It should be." Su Beibei said.
"Then I will help you." Lei Sheng also nodded: "When the time comes, you can introduce to me some other biological knowledge. And use your own body as a scientific specimen to explain it to me, okay? After all, I am a young man who loves knowledge and is diligent and eager to learn. Live and learn as you grow old. Only by continuous learning can people not fall behind."
"Well, of course." Su Beibei nodded.
"In ancient times, there were great people who studied for the rise of China." Lei Sheng said: "Now I, Lei Sheng, study for the continuation of human civilization!"
"..." Su Beibei was speechless.
"In ancient times, Confucius taught by words and deeds." But when she stepped into the bathroom, she imitated Lei Sheng's words and said while taking off her clothes: "Now I, Su Beibei, teach by words and deeds!"
"..." Lei Sheng hugged Su Beibei's delicate body and couldn't help but sigh: "Since you imitate the ancient saint's teachings on human body, then I can only imitate the ancient gentleman's way of stabbing the buttocks."
