President Cai gave Xiao Yuan an envelope in the lounge, this is the disaster relief money donated by the faculty and staff of Peking University, President Xiao, you collect it, there is not much money.

Xiao Yuan took it and handed it to Zi Yan: "Principal Cai, our husband and wife will leave, the victims of Huaxia will remember, thank you."

Principal Cai sent Xiao Yuan and his wife to the gate, and when he was about to call a rickshaw to take them away, Xiao Yuan excused himself, and then Professor Li walked out from behind the gate and said, "Principal, leave it to me."

President Cai repeatedly told Professor Li, and then he turned around and went back with confidence.

Xiao Yuan looked at this man in a blue cloth robe, a black horse coat, a pair of thin eyes on his round face and his drooping black beard, stretched out his hand and shook Xiao Yuan tightly.

said: "Our principal is also a good person, just made a rule for me, in the future I will receive a share of my salary, my wife will receive a share, I am too big, often can't see home, so I am very grateful to the principal!" When I went home, my wife was overjoyed to hear that a great doctor was coming. ”

Xiao Yuan and Zi Yan returned to Shi Fuma's house with Professor Li, this is a courtyard where people live alone, it is relatively spacious, the owner put it in order, a middle-aged woman greeted her, Professor Li hurriedly introduced: "Su Lan This is what you often talk about, the most famous doctor in China, Principal Xiao Yuanxiao and his wife."

"Hello sister-in-law, our husband and wife are bothering you," Xiao Yuan hurriedly said.

"Don't bother, don't bother, Principal Xiao is the holy hand of traditional Chinese medicine, I can see that it's fate, sit inside, you greet guests often, we will eat at once, is there anyone else?"

"Su Lan, and Changji's daughter and son-in-law, it should be almost there, let's go into the house to drink tea and talk."

Professor Li poured tea for the two of them and said, "Principal Xiao, the weapon in your speech today is really so powerful, can you tell me about it?"

"Professor Li, can you answer me a question first, what do you think the sun shines on?"

"The sun's glow, I really haven't noticed it, and I haven't thought about it, the sun doesn't shine there every day, don't care about it, Principal Xiao, you can tell me a rough idea."

"Slow, I also want to hear it, just now I went to the library of Peking University to look for "Mahabharata", but I only found a little record, saying that the book is the soul of India, and Huaxia has not found any books on this subject.

Xiao Yuan looked at a gentle, quiet, and virtuous woman beside the young man from Hunan, and when the young man saw Principal Xiao looking at the people beside him, he generously introduced his wife, and Xiao Yuan also introduced his wife to the woman.

The two girls of the same age became familiar at once, and they praised Zi Yan's dress very much.

"Principal Xiao, hurry up, don't hide it anymore."

"Alright! I speak to you, but don't spread it to the Great Powers. "

The two said in unison: "I know, say it quickly."

Xiao Yuan took a sip of tea and began to speak: "That has to start when I was a child, when I was a child, I always asked my parents what the sun burned, that day my parents were forced to be anxious, saying to burn coal, but I asked him why there was no smoke, he was asked by me urgently, hit me, and went to do his business."

My mother came to rub it with me and told me to read a book, saying that the answer was in the book, and after listening to my mother's words, I loved reading since I was a child. If you have a question, go to the book to find the answer.

Later, the "Theory of Relativity" was published, and the mass-energy equation was also available, and when I studied him, I found a response, although it was only theoretical, but I did not dare to publish it, because I found the fusion reaction of the sun, and from the fusion reaction I introduced the chain reaction。 !

You may be unfamiliar with these two words, so I'll tell you about them.

Fusion is the principle of the sun's light and heat, the reaction process in which two hydrogen atoms collide to form a helium atom, and in the process release high temperature and high heat.

The other is the heavy nuclear reaction, which I call the chain reaction, which is: K is the neutron, and U235 has two radiation reaction situations:

(1) The uranium nucleus is bombarded by one neutron and splits into xenon and strontium and releases two neutrons;

(2) Uranium-235 can also split into barium-144 and krypton-89 and release 3 neutrons.

All of them are high-temperature, high-pressure, and radiation, and the power of the explosion is two million times that of a chemical explosion.

Based on the above, I have designed ***,**, all of which are extreme weapons that destroy a city.

It is a weapon of heavy nuclear fission, and its main reaction material is U235, which is made of ***, so I can use it to make a fusion bomb**, and the main material is the isotope of hydrogen, deuterium.

The power is about 500,000 tons of T N T right and left, ** it is hard to pull, up to tens of millions, or nearly 100 million tons of T N T, if this weapon is obtained by the island country, it is not the sorrow of China, so I am very worried.

"Sure enough, it's really a big killer, I really have to keep it secret, go to dinner, Su Lan Cui has been a few times."

After eating, everyone sat and chatted in the living room, and Professor Li's wife proposed to let Xiao Yuan see a few children to see a doctor, and Xiao Yuan was happy to see Professor Li's children one by one, and there was no major problem, so he prescribed them some dietary prescriptions for calcium supplementation.

Professor Li praised that the national hand is the national hand, and even the usual meals are cured, and a few can't help but let Xiao Yuan diagnose and treat them again, Xiao Yuan showed them one by one, and prescribed Professor Li a prescription to calm the nerves, and prescribed a prescription for his wife to invigorate blood and remove stasis.

also prescribed a pair of constipation prevention for young people, saying that he ate a lot of spicy food, so he prescribed this for him, and then Professor Li asked him about fundraising, and Xiao Yuan also told them about the situation one by one.

Professor Li and the young people greatly admired Xiao Yuan's ability, and they were extremely happy to relieve the plight of the victims in the north in a few days.

Xiao Yuan saw that it was too late, so he proposed to go back, and Professor Li and the young man had been sent far away before saying goodbye to Xiao Yuan and his wife.

Back at the residence, Chanjuan ran over with the black panther, blaming Xiao Yuan for not taking him to a place where to eat and play, and even losing his temper there.

Zi Yan whispered to him in the past, and immediately coaxed him into laughter.

On the way back, the young man saw that his wife had an extra pair of jade bracelets. "Just ask who gave it,"

The woman said, "Mrs. Xiao gave me my sister's wedding gift, why can't I accept it?"

"No, I think it's too precious, and we can't return the gift. It's okay for Mrs. Xiao to send it, they are all gentlemen, gentlemen are frank, don't worry. We're going back to Hunan, and we don't know when we'll see each other again. I really don't want to part with these noble people! ”

"Yes! Principal Xiao and his wife are really a pair of talented people, especially Principal Xiao's knowledge is immeasurable, and he doesn't know how to learn it. In particular, his eyes seem to be able to see through everything. ”

"There are not many good people like this in Huaxia, fortunately we met, why did you still form a sister with Mrs. Xiao."

"Well, she's a few days older than me, and she's angry, but it's good to have a sister."

"How can a meeting be so good like this?"

"You don't know anything about your daughter's house," the girl thought silently in her heart, and her sister hoped that we would see each other one day.
