On the carriage to the eastern suburbs of Chang'an.

Li Chengqian is like sitting on pins and needles!

He thought back to what had just happened in the restaurant, and even felt a little unreal.

Why did he agree to let his sister study medicine, why did he dare to risk being scolded by his father to do such a thing, and why did he still take his sister to gather outside the city......

Lu Heng is because he likes Li Mingyu.

What is he trying to do!

Was it because I was moved by my sister's reason to study medicine just now?

Granny bear...... It's not angry, tears are really not angry!!

"Lu Heng, the reason why I was able to take Yu'er out of the palace was also to tell my father and queen mother that I could take her to the restaurant to learn more and see more, which could help her take charge of Zhongkui after she got married."

"Suddenly bring people to the eastern suburbs, how can I explain......"

"Isn't this selling dog meat on the head of a sheep!"

Li Chengqian's scalp tingled when he thought about it.

Especially because of what happened two days ago, my father sent hundreds of hundred horsemen to protect him.

Although those hundred horsemen are probably only secretly observing now, their whereabouts will definitely not escape their control.

It's okay now, it doesn't mean that after returning to the palace, the father and emperor will be fine!

But Lu Heng was very calm.

"Afraid of what? Your father can let you take her out of the palace, which means that he is willing to let the princess move freely. ”

"It's a big deal to tell him when I go back, because the princess admires Sun Simiao and wants Sun Simiao to teach herself some ways to nourish the queen."

"Questions? No problem, no lie anyway. ”

Li Chengqian: ???

The idea and pattern were suddenly opened.

Isn't this just a name that studying medicine can be accepted by a father!

He didn't know that Lu Heng's idea originated from all his peers in modern society.

Some people in their twenties have been working for several years, and they still have to have a curfew when they go home, so everyone has come up with all kinds of excuses to go out and return late.

Gathering with friends is said to be a business dinner, travel is said to be a company project inspection, and the list goes on.

Although he has no friends and no curfew, Lu Heng has never eaten pork and has seen pigs run.

When it comes to selling dog meat on a sheep's head, he is simply at his fingertips!

After the two teenagers discussed how to go back to deceive their father and mother, Li Mingyu was wandering outside the world.

She looked at Lu Heng's face, and her opinion of this person changed greatly.

If you put aside those Meng Lang's outrageous words and deeds, Lu Heng is actually a very good person.

At least, he is different from all the noble children in Chang'an City, and even different from civilians, merchants, royal families, and all men.

stared at Lu Heng's handsome face for a long time.

Li Mingyu suddenly asked:

"Lu Heng, seriously, who did you learn these things from?"

"Listen to the eldest brother, you also mentioned to your father that the five surnames and seven wang generations have been married, and there are many deformed children and crazy people."

"If these things are not investigated by the royal family, it is absolutely impossible for the family to spread the word......"

"Where do you know that?"

Li Chengqian's spirits were lifted -

This is also a question that he has hidden in his heart for a long time!

Lu Heng's mind turned.

It is impossible for him to take out the identity of his traverser, so he can't say that these things are in the history books, and the modern marriage law is also very strict.

Then you can only talk about the scientific basis, and then work backwards.

"I don't know, I just know some underlying logic, so I can quit backwards."

"The reason why people are born like their fathers or mothers is determined by the genes of both parties."

"There are dominant and invisible genes carried in everyone's body, for example, both parents have double eyelids, but they give birth to a child with a single eyelid, this is because both parents have dominant phenotype genes in the recessive genes, and together they may give birth to a single eyelid."

"Well, that's a little too deep for you, I'll be brief."

"It is the genetic differences between people that can reduce the probability of newborns having genetic diseases. The smaller the difference, the greater the occurrence of genetic disorders after coincidence. ”

"If there is a blood relationship within three generations, the probability of giving birth to a child who is sick will be much greater than that of ordinary people, that is, it is very likely that there will be the crippled children and madmen you say."

"Got it?"

After Lu Heng finished talking about junior high school biology, he saw that the eyes of the brother and sister in front of him were full of circles.

Stunned.

He scratched his head, not knowing what to say for a while.

If Lu Heng was a biology teacher, it would not be difficult to explain it to such a person who didn't understand it at all.

The problem is the basic knowledge of this kind of subject, and he can't teach his students in an orderly manner!

Half a day.

Li Chengqian shook his head and said:

"I always feel that what you learn is not the same world as what we learn."

"In practice, it's all as you say......"

"But if you want to pass on the knowledge in it, I'm afraid it's difficult for everyone to understand."

"Lu Heng, if you want to teach Yu'er to study medicine, won't you teach it the same way?"

Lu Heng thought for a while and said:

"That's not it, you're still too small."

"This knowledge can be studied slowly later, and there is no need to rush."

"The first step in studying medicine is anatomy."

"It's okay, when the time comes, find a few fresh corpses of death row prisoners, cut everything for her, and see the internal structure of the human body!"

Li Chengqian, Li Mingyu: ???!!!

………………

Eastern.

Sun Simiao is taking a group of doctors in Chang'an City to wander between the various Zhuangzi, looking at the situation of patients everywhere.

A voice suddenly sounded behind him.

"Old man, we're here to help you!"

Look back.

Sun Simiao's face darkened:

"You kid is finally willing to come over?"

"Wait a minute, why is there a girl here!"

Lu Heng and Li Chengqian stood together, and beside them, there was a woman with a hat.

The woman's head and face were covered, but it could be seen from that posture that she should be young and beautiful.

"Old man, let's take a step to speak."

Lu Heng didn't answer immediately, but pulled Sun Simiao to the side of no one before explaining:

"This is the girl I like, and she also wants to learn medicine with us."

"You should do me a favor, take her with you these days, and tell her about the success of the class?"

"I promise, after the matter is over, if you want to write a book about the medical skills you want to record, I will help you spread it all over the world!"

Sun Simiao was stunned.

What is this?

It's okay to take the girl you like to this kind of place, anyway, they have never understood Lu Heng's brain circuit.

The question is, let him give a lecture to this girl and teach medical skills, and help him spread medical books all over the world?

Sun Simiao reached out and touched Lu Heng's head.

"Have you contracted the plague? Hey, this forehead isn't hot......"

"Why are you starting to talk nonsense!"
