During this period of time, the summer is scorching, the heat is unbearable, ordinary people are leisurely sitting in the shade of dense trees, shaking a big fan, while chatting about various parents, or all kinds of gods and monsters, but also leisurely, interesting, although not as intuitive as the TV series of modern society, vivid, but the tone of the subdued and frustrated, the expression of the color, the whimsical plot is still fascinating, let people follow the development of the story and the imagination, go to the sky and the earth in the imaginary world to swim.

No, a bunch of us children were also sitting in the shade of the trees, listening to the stories of the old people in the gang, when suddenly a young man in the gang burst out with his hair and danced with his hands, interrupting our thoughts. It is estimated that the weather is too hot during this time, which is easy to make people feel impetuous, he thinks about it, he is upset when he is practicing, he thinks about it, and if he is not careful, he goes crazy. I saw that he looked crazy and crazy as if he was drunk, and shouted like Nietzsche: "I am the sun, I am the moon, I am the number one martial arts master in the world, who competes with the front-" and then involuntarily took the shining broadsword, slashed all the way, between the sword light and sword shadows, and between the sparks of calcium carbide, several towering trees with thick branches fell in response, which shows that the potential of people cannot be underestimated, especially when they are crazy.

Immediately after that, he cut down indiscriminately at our group of people, and it is estimated that in the chaos, we were seen as jagged trees, and we were caught off guard one by one, and we didn't have the heart to compete with him, so we were so frightened that we had to flee in the wilderness.

There are many snakes and insects in the caves in the back mountains of this gang, which is very dangerous, and the cooler places are also crowded with many people to practice, and the practice must be calm and calm, so this person probably did not choose the right place, he was impetuous, and he accidentally went crazy, but fortunately, the master arrived in time when he heard the news, and after a fight, he was subdued. After passing through the acupoints, he finally regained his composure, and after a long time, he turned the corner and got out of danger.

The Master said to him with palpitations: "Do you know, not to mention how terrifying the way you looked just now, if you want to hurry, you can't reach it, don't rush to hurry, besides, you are practicing on such a hot summer day, the weather is hot, and you are upset, you must be cautious, otherwise it is easy for evil qi to invade and go mad." The young man was also startled when he heard that he was crazy, and everyone couldn't help laughing when they saw that they were fine.

Only Xiao Fei muttered to himself: "This can't be done, I have to speed up the process." It is estimated that he is specializing in something, but the weather in this ancient world is not cool, and when there is wind, it is so-so, especially when riding a tall horse, when the armpit is windy, he only feels the enthusiasm of summer, and does not feel her anxiety, if there is no wind, it simply makes people feel that it is hell on earth, and it is difficult to move an inch. Especially for those of us who come from modern society and are accustomed to air conditioning, it is even more unbearable. Although the solution of the ancient people was to sleep on a stone bed, the cool air penetrated the bones and invaded the skin, but it was easy to get rheumatism, and the air circulation in the basement was not very good.

I hurriedly followed Xiao Fei's pace, as soon as I entered the house, I saw that he was already knocking and beating, it turned out that he was using the gurgling water to make a water fan that could be rotated by the water flow, the wooden six fan blades kept rotating rapidly, and the breeze came slowly for a while, it was really refreshing, I clapped my hands and applauded, "Xiao Fei, this wooden fan is really good, but why don't you take it out and use it, lest that person go crazy today, it's scary to think about." ”

Xiao Fei said unhurriedly: "I still want to make an air conditioning fan with ice cubes in it, don't you feel it?" The current wind is still a little hot, a little unsatisfactory, and it has not yet achieved the ideal effect of being cool, so you need to make persistent efforts." ”

A few days later, he was done and invited me to come and watch, and it turned out that Xiaofei had invented a set of hydraulic circulation equipment, which used a large fan wheel to rotate and generate wind, and then sent the cold air produced by the melting of the ice cubes into the house. At the same time, it also cleverly uses machinery to circulate cold water to the roof, let it go straight down along the eaves, form an artificial water curtain, stir up cool air, in order to achieve the purpose of cooling off, and then install water pipes at the four corners of the house to lead the water to the eaves. When the cool water circulates in the house, the indoor temperature will naturally drop, and the cooling effect is excellent, and the cooling effect is achieved. And also planted a variety of strange flowers and plants, the fan blows, the fragrance of flowers overflows, as if sprayed with air fresheners, the fragrance is gusting, endless. It is really "long pine and bamboo, thick green covering the sun, layers of mountains and strange mountains, quiet and deep, cold waterfall flying in the sky, bet on the big pond can be ten acres". For a time, the fragrance of flowers and birds, the fragrance of flowers hit people, and there was a cave.

I said enviously: "Xiaofei, you are very powerful, you are simply self-taught." It also improves the air quality in the air-conditioned room with the fragrant fragrance of flowers, which cannot but be said to be a major progress in the history of air-conditioning technology, accelerating the multi-functional development level of air-conditioning. ”

Xiao Fei smiled modestly: "This is not my initiative, in the end, I have to thank you, last time you said that the ancients were very powerful, some time ago I specifically checked the ancient documents, and if this is the case, our ancestors are really smart." I did it by emulating them. However, at that time, it was mainly used by the palace nobles, and the common people had not yet popularized it. It can be seen from the ancient books that the cool hall of the Song Dynasty not only sends cold water and cool air with wind wheels, but also arranges various flowers on the cistern and around the hall, so that the cold wind brings incense, and the fragrance fills the room.

I wondered, "Is it true? Our ancestors were so clever that they even invented air conditioning, which is amazing." ”

Xiao Fei's eyebrows danced and said: "You think, in ancient times, no matter how hot the weather was, it couldn't be hot." Thus, in the palace there was the first machine. In the imperial palace of the Han Dynasty, there were "air-conditioned rooms" for both winter and summer. The winter room is called the "Temper Palace", and the summer room is called the "Cool Palace". Judging from the records of the Book of Han, the refrigeration effect of the Qingliang Hall is excellent, and it is said that "the Qing room contains frost in summer". The building with air conditioning in the summer of the Tang Dynasty is called the Hanliang Palace. Tang Dynasty poet Zhang Zhongsuo's "Music in the Palace" in the so-called red fruit Yao pond solid, gold plate dew well ice; sweet spring will escape the summer, the stage hall dawn light condensation, what is described is the scene of the cool hall to spend summer. "Tang Yulin Haoshuang" records that it was a hot day, and Li Longji had to change his office location to the cool hall. Behind the seat, the water fan car, the wind hunts the placket. Yin and silent, looking up and not seeing the sun, the four corners of the water into a curtain flying, the seat contains freezing. In the Song Dynasty, the cooling design in the palace was fashionable, and there were also fans with mechanical principles, which were driven by blowers and used wind wheels. It can be seen that the means of refrigeration are very advanced and are realized through mechanical devices. I'm just drawing a scoop from a gourd. ”

I sighed and said, "Shibei should be impressed in three days, it seems that you have become Dr. Long." It's really erudite, admire, admire, it's better to be happy alone than to be happy, let's hurry up and show it to everyone. ”

When they heard the news, they were dumbfounded, dumbfounded, and did not understand what kind of monster this rotating thing was? Some of them could not help but draw their shining swords, and cut off their heads and heads, just as Don Quixote regarded the windmill as a monster, and wanted to get rid of it as soon as possible. Fortunately, they were stopped by Xiaofei in time, and some of them were trembling and scared, so they had to watch from afar. When Xiao Fei started the demonstration, I saw that he gently pressed the button, the fan, the air conditioning fan, and the water curtain all operated in an orderly manner, a cool breeze was blowing, the breeze was blowing, and their long hair was blown away wantonly with the wind, and the robes were also blown with the wind swinging, drumming, and those rich flowers, grass fragrance, also came to the face, making people feel refreshed and relaxed. They cheered this time, rejoicing at such a miraculous invention, because although the palace had air conditioning, the cost was too high, the people had not yet popularized it, and it was still such a poor and remote place.

Summer was cooler and more pleasant, and the gang never went crazy like that again. Everyone is eating freshly made ice cream and ice cream in the refrigerator, drinking refreshing iced wine, eating chilled fruits in the purple jade plate, and blowing the air conditioner, which is really a comfortable summer. Especially at night, when I used to toss and turn and couldn't sleep, now I can sleep peacefully. And while listening to the rustling sound of the bamboo forest, the gurgling sound of the stream flowing in the bamboo water pipe, the ticking sound of the air conditioner fan, looking at the vast and boundless ink-colored sky, the stars in the night sky, blowing the cool breeze, smelling the fragrance of flowers, it is really a fairyland on earth, it is really a beautiful summer.

Now blowing air conditioning fans has become a trend in Lizhou, and whoever doesn't have a fan is backward, so everyone has to buy one to keep up with the development of the times, just like many people in modern society must buy a house and a car. It seems that the Chinese throughout the ages are so unwilling to be left behind, so daring to be the first. Xiao Fei is very popular now, not only everyone hugs him and respects him, but he is still rich now, and his money belt is swollen every day, and he invites us friends to drink and eat meat in three days, it seems that he is really living a happy life in the Great Song Dynasty, and he feels a little happy.
