After five years of teaching support, Daming became an empire on which the sun never sets.

Chapter 270 The Scientific Basis of Shougong Sand
"Besides, I don't know this very well. I just saw the relevant introduction on the encyclopedia. The introduction on the encyclopedia may not be accurate, so I want to hear your own experience." Qin Yu said.

As an existence that has never been seen before, the strong curiosity cannot be suppressed.

""Huainanzi" said: Take one of the yin and yang of the new house guarding the palace, hide it in the urn, dry it in the shade for a hundred days, and use it to decorate the female arm to produce articles. Combine the yin and yang with the man, and they will be destroyed." Lingshu said.

"In addition, "Natural History" said: Lizards are also called winding, they are raised with utensils, and fed with cinnabar. The body is completely red, and the food is full of seven catties. It is cured and smashed with a pestle. A woman's limbs will not be destroyed all year round. Only sexual affairs then perish."

"So it's really made of geckos, lizards and other animals." Although she spoke in ancient Chinese, Qin Yu could still understand and sighed, "Actually, Shougong sand was first popular in the ancient courts. To test the chastity of the women in the harem."

"Because it means to protect the innocence of the palace and prevent the harem from being dirty, so the lizard has the name 'Shougong'."

"Furthermore, Shougong Sha does not only exist in novels and film and television dramas, but also has clear historical records. When Princess Yongning of the Ming Dynasty, Wanli's younger sister, died, the palace maid scrubbed her body and discovered Shougong Sha. .She is a woman with a tragic fate. Although she came from a noble family and has a beautiful appearance, her life is short-lived, and her son-in-law is weak and sick."

"Mister is really knowledgeable." Lingshu said.

"Shou Gongsha can distinguish chastity, what is the pharmacology of it? You are a master of Xinglin, so you should know." Qin Yu asked again, and explained: "I didn't mean to take advantage of you, I just wanted to discuss academics with you. "

"Shougong, also known as Tianlong, is cold in nature, while cinnabar is sweet and cool in nature." Lingshu said, "Take the nature of the two things 'sweet and cool', and make them travel along the three yang meridians of the arm, and combine with the yin energy of women. When it meets the sun, it will disperse."

This is her pharmacological explanation of Shougongsha, and she also uses the theory of yin and yang.

Qin Yu didn't know much about China's ancient theory of Yin-Yang and Five Elements, and he didn't want to study it. After all, a person's energy is limited, so he only listened to what she said.

"I saw a more 'scientific' explanation, saying that lizards are full of estrogen, and once they encounter male hormones, the female hormones will be neutralized by male hormones." Qin Yu said.

"What is estrogen?" Lingshu was a little at a loss, and the new term hormone touched her blind spot of knowledge.

Can't help staring at Qin Yu, his eyes full of curiosity.

"Estrogen is a female hormone, including estrone, estradiol, etc. It will promote the maturation of female accessory organs and the appearance of secondary sexual characteristics, and maintain normal sexual desire and reproductive functions...Estrogen is not only present in women, Men's... will also secrete a small amount." Qin Yu said, "Forget it, there are too many technical terms in it, and you probably can't understand it."

I really don't want to discuss with her anymore. The knowledge of the two is not at the same level, and it will be very tiring to discuss.

In other words, there is no common language between them.

"Although I don't understand much, Lingshu still wants to learn." What Qin Yu said was incomprehensible to Lingshu, and said, "Although I can only understand one or two tenths of what Mr. said, but It still helps me a lot.”

"Is it helpful to you?" Qin Yu was shocked, "I said so many technical terms, but you actually think it is helpful to you?"

"Well." Lingshu nodded slightly, "The estrogen that Mr. said, in Lingshu's view, is the female's Taiyin and Shaoyin Qi. Taiyin and Shaoyin also promote the appearance of women's characteristics and maintain reproductive ability."

How can you force an explanation?Qin Yu was dumbfounded.

Although she couldn't understand my technical terms, she was able to explain things she didn't understand based on her own understanding.

Is it smart?
Or smart?

"Sir, you are pedantic about heaven and man, please teach me more in the future." Lingshu said sincerely.

It's just that you read a lot of encyclopedias, Qin Yu thought to himself.

However, I still believed that I could help her.

What she knows is the traditional Qihuang technique, and her own theory comes from modern science.Communicating with her is an exchange between Chinese and foreign academics, just like 'sitting and discussing Tao'.

The so-called stones from other mountains can attack jade.

She can definitely absorb the knowledge and nutrition she needs from these scientific theories to improve her abilities.

But it can only help her improve, and it doesn't do her any good.Her medical skills are genuine, but her own theories are copied from encyclopedias, without any medical skills.

"Let's talk about it later when we have time," Qin Yu said.

"Then thank you, sir." Lingshu bowed to Qin Yuying.

"Do you still feel unwell?" Qin Yu saw that her body was trembling.

"No, sir, don't worry about Lingshu." Lingshu said.

"Yeah." Qin Yu nodded, "How is your penicillin extraction going?"

"I still want to ask my master for advice." Lingshu stood up and lifted the curtain of the back room. Qin Yu walked into the back room and saw that the table inside was full of various petri dishes, all made of pottery.

In the corner was a pile of moldy oranges, the raw material she used to extract penicillin.

On a piece of snow-white rice paper on the table, there is a small pile of crystal clear white powder, which she extracted by chromatography.

"You extracted the penicillin so quickly?" Qin Yu was very surprised.Staring at the pile of powder, I don't know if it's real penicillin or how pure it is, and this place has no conditions for testing.

"It's not difficult to follow the method taught by the master. The difficulty is to discover a new toxin." Lingshu said, "And Lingshu has also tested it. Penicillin is indeed very effective."

She also tried it herself?How did you test it?Qin Yu couldn't figure it out, and didn't bother to ask.

"If there is nothing else to do, then I will leave and come to see you some other day." Qin Yu suddenly remembered that there was something urgent to do, so he left, "As for the modern medical theories you want to learn, I will go back and sort them out. Time will teach you the system."

"Thank you sir, I will send you off respectfully." Lingshu saluted respectfully.

Seeing the back of Qin Yu walking out of the wooden house, Lingshu was very excited and murmured to himself: "Sir, in fact, what you said just now has the biggest benefit. For Lingshu, it is like a bolt from the blue."

"The spirit pivot didn't say it out, please forgive me, sir."

"You said that men also secrete a small amount of estrogen, so women must also have androgen. That is to say, men have yin and women have yang, which made Lingshu suddenly realize the way of yin and yang."

"There is not only Yin Qi or Yang Qi in a person, but both."

"The yin and yang meeting is in line with the way of heaven, not a single one."
