… The method seems very simple, but the molecular motion theory in modern physics shows that when the matter is heated, the molecular motion is violent, and the gap between them becomes larger. So the object will become larger, and the opposite will change, and the distribution of blood vessels in the human head will involve human anatomy.

It's easy to say, but it can be summed up in this principle. And put it into practice, but it is a technological leap of the times.

In ancient times, when encountering nosebleeds, most of them used herbal medicine or acupuncture. Whether herbs or acupuncture are used, the aim is to constrict the capillaries on the nasal mucosa. It's just that the ancients knew what it was, but they didn't know why.

Sun Dan saw that the students were interested, and he was also interested, and after Chen Hong's nosebleed stopped, he returned to the study house, and did not talk about Zhuangzi, so he simply told the little eunuchs about the structure of the human body, and raised the pen to draw a map of the distribution of the five organs. And talked about the role of major human organs.

The little eunuchs are also well-read and intellectually educated in the palace, and some people are not strangers to seeing doctors. But Chinese medicine pays attention to the five elements of yin and yang. It is fundamentally two different concepts from Western medicine. Sun Dan's set of medical theories is unheard of and unseen for people in this era, although there may be suspicions of heresy in it, but it is also eye-opening.

Although Chen Hong and others still have some disdain for the modern medical knowledge imparted by Sun Dan. Or don't want to admit this set of theories, but everything Sun Dan said is so fresh that people can't help but feel trapped in it.

Before you know it, it's noon. The day's lesson is over.

Sun Dan came to his senses at this time: "Hey, I was going to talk about Zhuangzi, but as soon as I talked about medicine, I delayed." Next time, next time! With that, he picked up the book and walked out of the book room slowly.

"Thank you, sir, all the little eunuchs stood up, and this time it was neat.

Sun Dan also smiled bitterly in his heart: Changming science is a good thing for the benefit of the country and the people, although I am determined to enter politics, but politics is a high-risk business. If the future career is not smooth. It is better to open a academy to educate the people. Enlighten the people. Democracy and science. Mr. De and Mr. Sai are the only way to promote the progress of the times. It's a pity. The readers outside blindly read the eight strands. I hope to change my personal destiny through reading. Those who can study and seek knowledge with peace of mind are probably the only ones who have no exam pressure, right? This is also a helpless thing.

This day's class is finished, and according to Sun Dan's schedule, he will eat in the inner study hall at noon. It's a little bit of Beijing time now. It's too late to rush home to eat. After eating, resting for half an hour, I went home to reunite with Zhiniang. I won't go back to Fangshan until early tomorrow morning.

As soon as Sun Danwang walked out of the bookstore, Lu Fang followed: "Sir, I'm going to have lunch, so let the students wait next to him." ”

"No, I don't. No

"Yes, yes

The people in the court waited for people, and it was really easy. Lu Fang led Sun Dan to the dining room, immediately wiped the tables and chairs with his hands and feet, and respectfully brought Sun Dan a bowl of rice. Sun Dan pointed to the chair next to him: "Let's eat together." small

Lu Fang seemed to be a little happy, and hurriedly thanked him. Rice was also served. Sit aside.

According to the rules of the school, the students have their own meals. Lu Fanglie had a very unpleasant quarrel with Chen Hong, and now that he has passed, he is afraid that he will be beaten. Now that he is by Sun Dan's side, Chen Hong can't do anything about him.

This kid is really a monkey spirit, and he looks so honest.

Sun Dan shook his head secretly, put down his chopsticks, and said to Lu Fang: "Lu Fang, you are one of the teacher's best students, and I am also optimistic about your future. However, to be a man, you have to be responsible and courageous. There are things that are impossible to avoid. I can't hide for a while. The teacher knows that you and Chen Hong have conflicts, but after all, they are both classmates, and there is no great hatred, what are you afraid of? Behave. Be brave when you encounter something

Lu Fang's hand was fixed in mid-air with chopsticks. Timidly shouted, "Sir."

Sun Dan smiled lightly: "When people are young, they feel that some things are as big as the sky, and when they encounter it, it seems that they can't live." But after many years, I encountered many things, and I looked back. Actually, it's not a big deal. ”

When has Lu Fang ever heard such heart-to-heart words. I saw Sun Dan's kind eyes. Tears suddenly fell. He carefully placed the chopsticks on the table and said, "Sir, since the fall of my godfather, I", my life is worse day by day, although people can bully me. Especially that Chen Hong, who is playing tricks on me all day long. The slightest disobedience is a punch. ”

Sun Dan: "What happened to you last night." Did you go to the casino with Chen Hong? ”

En Lu Fang lowered his eyelids and replied, "Chen Hong likes to play horse hanging. It stinks. See the day to lose money. I owe a lot of money to people. was chased by people and chased hard, and they were about to be driven crazy. ”

The so-called horse crane is mahjong. Merely. Horse hangs are solitaire, while mahjong is dominoes.

According to the research of later generations, the guide was popular in the Ming Dynasty during the Apocalypse, as for when it was Ming, there is no way to test Sun Dan now knows, this thing is at least in Zhengde's previous things. ……

The horse crane is divided into four colors: 100,000 guan, 10,000 guan, rope and money. Thereinto. Wanguan and Suozi are two colors from one to nine; 100,000 is from 20 to 900,000, and even one for million, 10 million, and 10,000; The money is from one to nine, and even half and no money.

Sun Dan smiled: "Isn't Chen Hong Huang Jin's godson, and someone dares to ask for his account?" ”

A hint of sarcasm suddenly flashed on Lu Fangmune's face: "Gonggong Huang is now the carp who is willing to be his son in the Red Palace. Now. The sons of the Huang family have not a thousand but eight hundred, but I am afraid that after the Huang father-in-law accepted Chen Hong on a whim, he turned around and forgot about him. Moreover, Chen Hong owes Dongchang Zhong's father-in-law money. Gonggong Zhong is the godson of Bi Yun Bi's father-in-law. Others are afraid of Huang Jin, but Bi Gonggong is not afraid. That Chen Hong owed Zhong Gonggong money, and the net was not much at the beginning, only five yuan, but because Chen Hong's playing skills were too stinky, he would lose every time he gambled, and he owed Zhong Gonggong three taels one after another. What kind of person is Gonggong Zhong, that is the fan in the East Factory, and he is a loan shark. After a month, Chen Hong now owes more than 100 taels to others. ”

"Ah, so many?. Sun Dan was a little surprised: "This Chen Hong is really bold, dare to owe such an account?"

Lu Fang: "Chen Hong's courage is not too small, but he owes so much money to people, and his life is also sad." Seeing the sky, it was cleaned up by the people of the East Factory. Not only was all the monthly money confiscated, but even the two sets of winter clothes that came down from the net this year were not taken away by the father-in-law of Dongchang. ”

Only then did Sun Dan remember that the palace clothes on Chen Hong's body were very thin before. There are still patches in many places. Apparently last year's old outfit. He couldn't help but shake his head and sighed, "This kid." ”

Sun Dan asked again: "So, what happened yesterday?"

Only then did Lu Fang say: "Back to Mr. Hui's words." Chen Hong was also anxious when he saw that the sky was cleaned up by the people of Dongchang, and he was beaten all over the ground in three days. Yesterday after dinner, he brought a few thugs to us to steal money

"Grab money?. Sun Dan "fluttered". One voice: "You guys." The month is only one tael of silver, and he owes more than a hundred taels to others, does he want to rob more than a hundred people in one go? "If this Chen Hongruo is placed in modern society, he is a learning overlord. Specialized in bullying junior students.

"He didn't steal money to pay off the debt. It's about raising a gambling capital. Lu Fang's eyes fell on the food. Swallowed a mouthful of saliva.

Sun Dan lifted the chopsticks: "While eating, I said that it would not taste good if it was cold, and my stomach would hurt if I ate cold rice."

"Thank you, sir, Lu Fang is probably also hungry, and it's time to grow your body again. hurriedly took a bite of food, and then said: "Recently, a casino has opened in the capital, what is it called Sihai Casino, and there are many tricks in it. But there is a point. The bookmakers inside have a lot of hands and often lose money. There are quite a few people who have won a lot of money in it. Chen Hong gambled with people in the palace and never won. When I heard that there was such a good one outside, I moved my mind and wanted to make a profit. So, he also took the money. Been there a few times. ”

"And then?" Sun Dan sandwiched a piece of braised pork and put it in Lu Fang's bowl: "Move the chopsticks, move the chopsticks."

The corners of Lu Fang's mouth were oily when he ate, and he was not as restrained as before, and said with a smile: "Others may be able to win some when they go to the Four Seas Gambling House, but Chen Hong can't." His stinky hands, even if he meets a generous dealer. It's the same to lose cleanly.

I went there several times, and each time I went back to the palace naked. But Chen Hong was just not convinced, and yesterday he came here with us and grabbed a few taels of silver. Said to go out and turn the book. ”

"He grabbed the money and went on his own. Why did I bring you with me? Sun Dan was strange in his heart and asked.

Fang was a little ashamed: "Back to Mr. Son's words." Although Lu Fang doesn't gamble, he has a bright brain. Horse hanging is very powerful. Chen Hong finally admitted that he was not good at his craft, so he asked me to help him play cards

Fang: "I can't help it, I was carried out of the palace by Chen Hong, and then entered the gambling." Originally, "everything went well. With my craft. In less than an hour, he won several taels. But Chen Hong felt that it was not a way to fight like this. I don't know if the Year of the Monkey will be able to win back the money he owes to others. I hid a few cards. Hand it to me at the critical moment. I want to be a big name. A few handfuls down, aroused the vigilance of the casino people, and they were also arrested.

So, the thugs in the casino came out. Give Chen Hong a good beating

Speaking of this, Lu Fang chuckled gloatingly: "Fortunately, I saw that the situation was wrong, and I threw the cards and ran, and finally no one was caught." ”

Sun Dan was a little surprised: "What is the origin of this casino, how can even the eunuchs in the palace dare to fight?"

Lu Fang replied: "I heard that the casino owner seems to be a relative of Zhang Guifei", then it is no wonder that Sun Dan knew it in his heart. I heard that Zhang Guifei is being favored, and the emperor also intends to make her the queen, no wonder his family is so happy. However, Sun Dan still moved in his heart: Zhang Guifei's relatives, is it Zhang Qiangrose's father and daughter?

Sun Dan thought about it slightly, and the more he affirmed his guess in his heart.
