What is youth?

For many people, youth is to fall in love in the most beautiful years, not too many times, at most twice, because too much will be flooded, and if there is no once, the best years will be wasted.

The June sun is a bit hot for most northerners, and even in the evening, with the sound of knowing the knowing, the university dormitories are full of stuffy atmosphere.

Air conditioning does not exist, don't be deceived by the beautiful pictures in foreign TV dramas, in most universities in China, except for international student dormitories, ordinary student dormitories will not have air conditioning. Therefore, summer is undoubtedly extremely difficult for many people.

"No, I'm going to die of heat!" Jiang Zhi was shirtless and couldn't help but shout loudly.

It stands to reason that when the final exam is over, there should be a summer vacation, but for the college student art festival, several colleges and universities in Binzhou have advanced the exam time, so even if the final exam is over, Ye Leiyang and they still need to stay in school for more than half a month, and because the weather is too hot, the whole school is like a steamer.

Especially the men's dormitory is not quite the same as the girls' dormitory, at this temperature in summer, the various flavors in the dormitory are called delicious, fortunately, Zhao Dongjian and Wang Chaoyang usually clean it occasionally, otherwise Ye Leiyang's dormitory is estimated to be like the dormitory where Xiao Zhengjun is, and people can faint as soon as they open the door.

It is said that it is completely said that in the dormitory where Xiao Zhengjun and his group of people are located, no one from the student union dares to go to check the dormitory in the summer. The reason is simple, I can't stand the smell!

Ye Leiyang thought of a way and made a few basins of cold water in the house, hoping to cool it down, but the room was a lot damp, but it still made people feel hot and flustered.

"Let's eat popsicles." Zhao Dongjian took out a popsicle and threw it to Jiang Zhi, and took one himself, it is undoubtedly a happy thing to have a popsicle to eat at this time.

Ye Leiyang also lay on the bed with no energy at all, in such weather, he really didn't have the energy to do anything.

The severe cold and heat are definitely the two major enemies of mankind, which can completely consume people's sharpness and energy.

"In this weather, it would be nice to have an air conditioner." Jiang Zhi said helplessly: "I heard that there is air conditioning in the dormitory for international students, tsk, that taste, it's so cool!" ”

"Air conditioning?" Zhao Dongjian sneered: "Dream, our school may install an air conditioner for you, I see that you haven't woken up." ”

Several people know that Zhao Dongjian is telling the truth, although the price of air conditioning is not too expensive, it is definitely a luxury for students, and the school will not agree to students spending money to install air conditioning in the dormitory, which is simply a torture, even if you have money, there is no way to solve the torture.

"Actually, I can do it." At this time, a weak voice sounded in the dormitory.

"What to do, fourth, don't talk nonsense." Ye Leiyang waved his hand and said to Wang Chaoyang, who was speaking, but the next moment he suddenly realized what Wang Chaoyang had just said, and sat up suddenly: "Wait, what will you do, fourth?" ”

A touch of unnaturalness flashed on Wang Chaoyang's rigid face, and he hesitated for a moment and said, "Cool down." ”

"What's going on?" This time, even Zhao Dongjian sat up and stared at Wang Chaoyang and asked.

Wang Chaoyang thought for a while and said slowly: "There are too many materials needed for air conditioners, and if you want to make them, you need equipment." But if it's just refrigeration, I think I can do it. But I need you to find me some materials. ”

After a pause, he seemed to be afraid that a few people would be unhappy, and added: "I have only designed this thing theoretically, but not practiced. I designed it at home when I was in high school, but I gave it up because I didn't have that much money and couldn't buy materials. ”

Jiang Zhi swooped up: "What do you say, I have money!" ”

What are you kidding, it's almost hot to death, and now as long as someone says that it can lower the indoor temperature and spend three hundred and five hundred, Jiang Zhi doesn't frown.

Ye Leiyang was still relatively calm, and he asked Wang Chaoyang: "What do you need?" ”

His idea is very simple, after all, it is something similar to the air conditioner, if the value is too high, there is no need to do it, anyway, everyone is about to have a summer vacation, and a few days of patience will pass.

Wang Chaoyang was not polite, picked up the pen and wrote and drew on the table for a long time, and finally slowly spoke: "Two 12 cm and 4 cm fans, as well as thermal grease, two semiconductor cooling sheets, two heat sinks, and a cut heat insulation pad, oh, and a 12-volt power supply, that's all." ”

"Huh?"

At this moment, whether it was Ye Leiyang, Jiang Zhi or Zhao Dongjian, they were all dumbfounded, because all these things that Wang Chaoyang said were ordinary parts that could be bought on the market.

"Uh, Chaoyang, you're not kidding, are you?" Ye Leiyang hesitated and asked Wang Chaoyang strangely.

Wang Chaoyang tilted his head and thought about it: "By the way, I still have to buy some screws or something, as well as a screwdriver." ”

Ye Leiyang and the three of them looked at each other, and suddenly they couldn't understand the world of Xueba, they didn't understand how these things could be combined into an air conditioner.

"Well, let's go shopping." After a long time, Ye Leiyang opened his mouth and said to Zhao Dongjian and Jiang Zhi.

After getting along for such a long time, they can be regarded as understanding Wang Chaoyang's personality, although he is usually a little wooden, and even conformist and old-fashioned, but Wang Chaoyang's character has always been one thing to say, and he will never open his mouth if he can't do it. So since he said that he could do it, then the problem should not be too big.

A few people didn't dare to hesitate, and after a rush, they got dressed, but fortunately, they wore less in the summer, and although the big pants and slippers looked a little casual, they were definitely the standing supplies for the boys of Northern University.

Soon Ye Leiyang and Zhao Dongjian carried their things back to the bedroom, and Jiang Zhi personally accompanied Wang Chaoyang to the hardware store and asked the other party to cut the heat insulation pad according to his requirements.

A bunch of parts were placed there, and several big boys looked at each other: "Is this okay?" ”

In their opinion, the pair of parts on the table did not look like something that could cool down. The most important thing is that several people are not very hands-on people, and they know nine out of ten about these things—they don't know anything about them.

Wang Chaoyang smiled, walked to the table unhurriedly, and began to assemble it.

Time passed minute by minute, and in less than an hour, the parts on the table disappeared, and a somewhat ugly-looking machine appeared in the sight of Ye Leiyang and the others.

"Can this thing work?" Jiang Zhi looked at Wang Chaoyang with some suspicion.

Wang Chaoyang shrugged, closed the doors and windows, and gently pressed the switch.

"Cool!"

Ten minutes later, Jiang Zhi heard a wolf howl from the dormitory.
