Du Yu chose to return, and he was greeted by a warm home, busy university life, and familiar faces with his classmates. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

It's business as usual, just like he had experienced before, getting up in the morning, then having breakfast or running in the morning, running to class with his school bag in his hand, and helping his buddies answer by name in college class.

Life is very routine, very ordinary, at first glance, he has not changed anything major because of this adventure, if the physical strength does not count.

Gradually, however, something began to manifest itself.

He has become a little stranger than before, and when no one is around, he likes to be alone in a daze and thoughtful. When there are people, they immediately put on a smiling face to welcome people, and the sincerity makes people feel even a little contrived.

The classmates in the dormitory are still very close to each other, if you look at it from a bystander's point of view, there will not be any sense of disobedience, but Du Yu himself clearly feels that he and others are beginning to have something that they can't fit in. He began to be a little condescending unconsciously, and he himself knew very well that this was not good.

So he gradually began to spend most of his time in the library, and he developed an instinctive resistance to the people around him.

"Hey, Du Yu, let's go play football?" Roommate Wang Kai came over and asked with a smile on Du Yu's shoulder.

"Ah no, I'm not going to go yet, I have something to check in the afternoon, and I want to go to the library." Du Yu was stunned for a moment, and refused with a smile.

"Wow! You're so studious now, so if you don't go I'll go by myself! Wang Kai made an exaggerated expression of surprise, then grimaced, and trotted away all the way with the ball upside down.

The days in the north, in the summer, are just as hot and unbearable.

Du Yu can't help but miss the comfort of material life in the mission world under this high hanging sun, people are like this, they complain about that when they have this, they are often dissatisfied, but it is precisely because of this that people have the idea of working hard to drill and climb up.

Holding his schoolbag, Du Yu strode into the library, already sweating slightly.

On the third floor, there are medical books, and he is very serious and easy to learn now.

Du Yu, who has experienced the society, knows very well that knowledge is not learned in vain, you may not need it now, but when you use it, you must understand it.

"All diseases have sounds, drums are like drums, all belong to heat."

"The cold is kind to the skin, the yin is strong, and the yang is deficient, so it is to shake the cold and shiver"

……

"Filter out one-third of the trickle and dry it for two-minutes, for the end."

"The cold is outside, blocking the yang road, so the upper focus is not passable, the guard qi is not warm on the surface, and the cold is left alone, which is a chill, and this yang deficiency is cold outside."

"Diamagnetic vs. paramagnetic: oxyhemoglobin is diamagnetic, deoxygenated hemoglobin and orthohemoglobin are paramagnetic, and hemosiderin is superparamagnetic. Although deoxyhemoglobin and orthohemoglobin are both paramagnetic, the position of iron atoms in the hemoglobin framework is different, which also affects the NMR signal performance. ”

A sentence was recited in Du Yu's mind, and it was written under his pen, and before he knew it, it was an afternoon.

When I came out of the library at about six o'clock in the evening, I happened to meet an acquaintance on the small campus.

A beautiful girl walked over, wearing a white shirt on her upper body, a short black skirt underneath, and two snow-white long legs exposed, it was Du Yu's college classmate Yin Yuehua.

"Ah, isn't this our Du Da talent, hehe, why did you come to the library again." Yin Yuehua and Du Yu are quite familiar with each other, and greeted with a smile.

"Isn't it okay for me to do anything, it's still hot outside, so I just hide in the library" Du Yu also replied with a smile.

"Haha, if you soak in the library all day like this, you will become a nerd, be careful not to find a female ticket."

"Is it possible for an outstanding young man like me to be a single?" Du Yu said disapprerovitically.

"That's not for sure." Yin Yuehua joked narrowly, and then, his eyes fell on the umbrella on the side of Du Yu's schoolbag, and said, "On a sunny day, why are you bringing an umbrella?" ”

"Didn't I let the rain rain scare me these days?" Du Yu said perfunctorily.

Yin Yuehua raised his head, looked at the sky, shook his head and said with a smile: "Look at the sky, it's so clear, there are not a few clouds, how can it rain?" You're almost the same as worrying about the sky! ”

"My home is in the capital, and the weather can change this May, and there may be a rain pouring down at some point." Du Yu said worriedly.

"Look, what you're saying looks like it's going to rain in a real moment." Yin Yuehua sneered

"This is a real experience, don't laugh if you don't believe it." Du Yu saw that Yin Yuehua didn't believe it at all, and said softly.

"Say you're fat, you're still panting, hahaha, or let's make a bet." Yin Yuehua proposed.

"Okay, how do you say you bet?" Du Yu thought about it, and if there was nothing to do, he agreed.

"Let's bet on whether it will rain before 8 o'clock today, how about it? The loser has to treat him to dinner," Yin Yuehua raised his chin and asked with a provocative smile.

"Okay, no problem." Du Yu agreed with a smile, they are all friends, and it doesn't hurt to laugh and laugh.

"Thank you first." Yin Yuehua smiled.

"Thanks for what?" Du Yu was stunned for a moment, and suddenly reacted: "In case it rains, it will be embarrassing, hahaha"

Yin Yuehua chuckled, looking like a conspiracy had succeeded, and said: "I'm sorry, Du Dacai, I read the weather forecast yesterday, and the weather forecast said that it was sunny and cloudy, and there was no mention of rain at all, hum~"

"Beijing is a large city, there are more than a dozen districts and counties, and this weather forecast only represents most of the regions, maybe there is a dark cloud above your head." Du Yu didn't care either, and said with a smile

"Then let's wait and see, and see which one is more accurate, you or the weather forecast." Yin Yuehua has the winning ticket in her hand, and she has already begun to think in her head about asking Du Yu to invite her to eat something. Since it is a dinner treat, it is natural to go and eat something delicious.

The two walked on campus, and soon came to a fork in the road, Du Yu was ready to go back to the dormitory, Yin Yuehua was going to go to the study room to write a script, she was the deputy director of the broadcasting and hosting department of the student union, and she was asked to host the singing and dancing party after a while, so she naturally had to prepare well.

At seven o'clock in the evening, Du Yu, who was taking notes in the bedroom, looked at the sky that had darkened, and suddenly his right eyelid began to jump involuntarily.

Suddenly, a flash of lightning flashed through the window

"Boom" There was a loud bang, the thunder moved in the nine skies, the sky was turbid, the electric light cut through the sky, the slam rotated, and the lightning was terrifying!

The rain poured down and came down with a bang

Du Yu was a little proud, he didn't expect that it would really rain.

took out his mobile phone at the moment, and was ready to call Yin Yuehua, on the one hand, to remind himself that he had won the bet, and to be ready to make fun of her, so that she was willing to gamble and lose. On the other hand, I also want to ask her where she is and send her an umbrella, after all, good friends can't watch her being watered!

1594018672, just as he was about to press the dial button, a call came in, and the note was Mom.

"Hey, Mom!"

"Hey, son, what are you doing?"

"I'm at school, in my dorm room, writing notes."

"Can you come back?" The mother's voice was a little low, slightly hoarse.

"What's wrong? I'll go back in a while" Du Yu was stunned for a moment, and then looked at his watch, it was less than eight o'clock.

"It's nothing, it's just that your grandfather is sick, it's quite serious, so I asked you to come back and have a look."

"Okay, let's go back and talk about the specifics." Du Yu put down the phone, sent a text message to the counselor to ask for leave, and then said hello to a few classmates in the dormitory, put on a vest, held up an umbrella and walked to the nearby bus stop.

In the rain, the wind was strong and the road was slippery, Du Yu walked very carefully, and he remembered his grandfather's face. I was anxious, and my nose was slightly sour.
