"After suffocation, the human body will indeed produce a toxin on its own," Zhang You said along Li Shizhen's train of thought, secretly admiring, the other party is worthy of a generation of miracle doctors, and the "toxin" should be carbon dioxide: "This has to start with the qi we breathe, and the younger generation has studied a little bit, and found that the qi we breathe is not simple, but contains many components, among them, the most important one used to maintain respiratory survival is one ingredient, which the younger generation calls oxygen, which is also the key to the combustion of objects." When the human body inhales oxygen, it emits another gas, which later generations called carbon dioxide. In addition, plants actually need to breathe, on the contrary, they inhale carbon dioxide and exhale oxygen. As for coal poisoning, to be precise, it is a toxic gas, carbon monoxide, which, when it enters the human body, prevents oxygen from combining with certain components in the blood......"

Zhang You said it vigorously, but others listened to the book of heaven, including Li Shizhen, he endured it for a long time, and finally couldn't help but interrupt Zhang You: "Wait a minute, it's too complicated, why haven't you even heard of so many things you said?" Why does blood want to talk to you about it...... Oxygen combined? Also, plants need to breathe, which ......"

Zhang You actually knew that they didn't understand, and the reason why he still wanted to say it was just that he felt that this was a good opportunity to popularize the common sense of medicine in later generations, you know, there was a miracle doctor Li Shizhen in the audience, he believed that as long as he explained in detail, the other party would definitely be able to learn something from it, so as to make greater achievements.

He had been waiting for this question for a long time, and when he heard the words, he smiled slightly, and said to Sihan: "Go, bring a pen and paper," and turned his gaze back to Li Shizhen: "I can't say a sentence or two, or the younger generation will draw it for you......" When he spoke, Sihan had already taken the pen and paper, he took it in his hand and first drew a sketch of blood circulation, and then drew a sketch of plant circulation, and began to explain photosynthesis to Li Shizhen, about oxygen combustion, and about the process of converting human food into energy, Arrange yourself to be in a thatched hut to absorb the principle of natural oxygen therapy......

Listening to Zhang You's explanation, Li Shizhen seemed to have entered a very unfamiliar field, novelty, surprise, admiration, and a variety of emotions were intertwined, he really couldn't imagine how Zhang You knew so much knowledge at such a young age.

Mary came in halfway, and was immediately attracted by Zhang You's content, listened to it with relish, and asked a puzzled question from time to time, but she was always able to get a trustworthy answer, and she couldn't help but admire Zhang You more and more - she came from the West, and she had more contact with them than Li Shizhen, and there were some things that the West had begun to study, and she also understood, which was the reason why she admired Zhang You the most.

As for the rest of the people, they listened to some meaning at the beginning, and the more they listened, the more confused they became, and finally they simply left one by one, no way, it was too profound, and the more they listened, the bigger their heads became.

Zhang You expected it to be good, the day after he woke up, Ji Rong came to visit early in the morning.

I talked with Li Shizhen last night, and I didn't rest until the second half of the night, Zhang You's eyes were bloodshot, and while washing his face with cold water, he explained to Sihan: "Let him wait for a while, I'll go over after washing." ”

Sihan hurriedly went out, and Lan Qi handed over a wrung out towel and complained: "The conversation is endless, and so is the old doctor, who is old and doesn't know how sleepy." ”

"Thirsty for knowledge, Wei compiles three uniques, and the aftermath lingers ......"

"Stop, stop, I know you're knowledgeable, don't show off, okay?" Lan Qi glanced at him, saw that he finished wiping his face, pressed him to sit in front of the dresser, gently helped him comb his hair, and changed the topic: "You have been with me these days, and you have time to accompany your aunt, they are all women, it is not easy for her to take this step, you can't be sorry for her." ”

Zhang You nodded, took her hand and kissed her on the back of his hand: "Sister Qi, you are so good." ”

Lan Qi forcefully pulled her hand out of Zhang You's hand: "What's it, stupid...... I think Mary is also interesting to you, and Sihan, it's the beginning of love, you can take it easy, I'm thinking about it, if there is a suitable one, I really have to tell her about her mother-in-law, that Fang Congzhe is very good. ”

It was fine just now, but in the blink of an eye, the vinegar came up.

Zhang You smiled secretly and said: "Mary is okay, you know, I am interested in maturity, Sihan, you can rest assured, I will never provoke...... Fang Congzhe is really good, don't look at it as a lifter, Sihan This kid is affectionate and righteous, and he is also beautiful, and he is more than enough to match him. Let's wait for the end of the spring festival to see how he did in the exam, and if he does well in the exam, find someone to talk to them. ”

Lan Qi nodded, and couldn't help poking Zhang You's temple with her finger again: "You really think about Mary, little villain, you have to tell Jia Lin when I go back to Beijing." ”

"You won't say it, and besides, I'm just thinking about it, but I haven't actually acted." After saying this, Zhang You found that Lan Qi didn't squeak, looked in the mirror, and saw that she seemed to be in a daze, and hurriedly asked, "What's wrong?" Really angry? ”

"No, Zicheng, it's good to know you!"

Zhang You was stunned: "It's so decent, how can you talk about this?" ”

"You don't understand, you are the most unique man in the world, and being able to be your woman is the greatest luck in my life...... It's strange to say, why don't you think my stomach has moved? Lan Qi suddenly changed the subject.

Zhang You was a little confused, but he didn't delve into it, and smiled along her topic: "So you want to have a child?" I want it too, let's work hard tonight......"

Lan Qi blushed, but she didn't object, and then suddenly exclaimed: "It's wrong, I'm patronizing and talking nonsense with you, Ji Rong is afraid that she is in a hurry, right?" ”

"Wait a minute, just kill his sharpness." Zhang You said indifferently, and asked instead, "Auntie, I haven't seen her yet." ”

"I went out early in the morning, and there has been no clue from Lao Xu for several days, she said to go out and try her luck."

Zhang You was silent, so Lan Qi also fell silent.

After a long time, after packing up, Lan Qi personally helped Zhang You put on his coat and went out with him.

"Young master, you can figure it out, the slave maid asked Master Ji to wait in the hall on the first floor." Sihan had been waiting outside the door, and hurriedly stepped forward when he saw the two of them coming out.

This is a small two-story building, similar to the small independent courtyard house in the north, equivalent to the presidential suite of an inn.

Zhang You and Lan Qi went down the stairs down the stairs, and before they entered the hall, an old man with a white beard as white as snow came out of the door, bowed down from a distance, and said tremblingly: "Grass people Ji Rong, meet Master Zhang, meet the second * grandmother!" ”

Stretching out his hand not to hit the smiling person, the other party was courteous for a few weeks, Zhang You was stunned, and secretly sneered: "You are worthy of the old fox, your skin is thick enough." ”
