A month later, on the day of the science and technology exhibition, the sun was shining and the wind was warm, and the exhibition was held in the football stadium~

"Did you hear that? Later, the student council will also come to see the exhibition. ”

"Really? Great, the student union is full of talented and good-looking handsome guys, so excited~"

"Moreover, he also said that he would select the best from this exhibition and accept that student into the student union~"

"Huh? Doesn't the student union accept people based on the results of the big exam every year? ”

"Well, I heard that it was newly proposed by the president of the student union, saying that 'talent training should be done as soon as possible, and you don't have to look at the year-end results, and you can also enter if you have excellent ones."

"That's good~ You said that with our relationship with the president, will you choose us?"

...

Listening to the discussion of several girls two meters away, Xiao Tao turned his head to look over there, and wanted to ask, "Is it good to enter the student union?" ”

Without waiting for her to ask, it seems that this issue has also been discussed over there~

"The teachers and materials of the whole school are given priority to the student union, and various off-campus competitions are also given priority to the members of the student union, so each of them has a lot of honors, patents, and bonuses."

"Wow~ The treatment is so good, I'm really envious."

Xiao Tao thought to herself: "Resources first? Why do you sound like the student union is very bureaucratic~"

A girl over there continued: "People also pay hard, they belong to national scientific research institutions, and they are on call 24 hours a day, whether it is a war or a plague, as long as they need the assistance of artificial intelligence, they may be called at any time~Can they have some privileges~"

"Wow~ I also want to join the student union."

"You~ just think about it~ let you get up at two o'clock in the middle of the night to intercept the enemy's secret report, and then don't sleep all night to decipher, don't say whether you can do it technically, just stay up day and night, you can't stand it for a long time."

...

When Xiao Tao heard this, she couldn't help but admire the student union~ At this time, she was standing next to her display works, waiting for the exhibition to start, and the girls who had just discussed next to her, one of them was Xiao Tao's classmate, and the rest were probably the little sisters of the female classmate. The female classmate's exhibit is a robot in a ballet dress, presumably drawn to Italy, Xiao Tao looked at the robot in the white gauze skirt, and the picture of the scramble for robots in the laboratory that day appeared in front of her eyes... I felt sympathy for the robot.

After more than 20 days, Xiaotao finally made a work that she was satisfied with, her eyes were inflamed, and she was a little red and swollen and afraid of light, so today she wore a pair of sunglasses and stood quietly in front of the exhibits alone~

The exhibition began, and people entered the venue one after another, and everyone was in groups in front of the various exhibits... After about 10 minutes, something seemed to have happened at a side door of the football field, and the people who were originally scattered around the venue ran over, and Xiao Tao's eyes followed~ A few minutes later, the congested crowd over there began to restore order, and Xiao Tao finally saw clearly...

One color uniform and more than 10 boys of about the same height are walking over from booth to booth, led by Leng Ruoyi! His face looked extraordinarily fair in the sun, his slightly curly hair was glowing with chestnut light, and the other 10 boys seemed to know Leng Ruoyi's temperament very well, forming a semicircular human wall at a distance of one meter from Leng Ruoyi, blocking the fans who came over. Xiaotao then understood why the female classmate just said that she would be elected to the student union based on their relationship, it turned out that the president was in the same class...

In this way, as soon as the student council entered the venue, it was like a big magnet, sucking everyone over, forming a long line, following the student council to see the exhibits one by one. After a while, I came to the vicinity of Xiaotao, first walked to the booth of the female classmate next to me, the female classmate was busy controlling the robot, the robot began to rotate in place, one hand in a semi-circular arc on the chest, and the other hand above the head, but the two big soles were all attached to the ground~ I saw Leng Ruoyi glanced at the afterglow, and continued to walk forward without staying half a step... The next two student council members said:

"Every year there are opportunistic ~"

"Oh, I've never seen a ballet with the soles of my feet."

Subsequently, the large army did not stop following the pace, and the female classmate had already blushed~ But Xiaotao has no leisure to watch the excitement now, and Leng Ruoyi is in front of her~

Xiao Tao began to show his works: on the surface, there was a rectangular iron sheet 8 meters long and 3 meters wide and 5 meters high on the booth, with countless dense pores on it, and after it was started, there was a melodious orchestral sound, and the holes on the rectangular iron sheet began to overflow with unknown liquid, which made everyone's scalp numb and called disgusting~

The liquid continues to extend outward, the liquid overflowing from each hole has its own trajectory, the length, width, angle, and final imaging of its stretch in the air are all set, which is hidden behind a large number of calculation formulas, the liquid gradually condenses in the air, about 5 minutes later, it actually presents an ancient building with black, he, red, vermilion as the main color, is a city wall, the city gate is lined with black beast patterns, the city gate is written with three big red characters "Qin Palace"... The crowd began to shout in admiration.

Immediately afterwards, the condensed building began to slowly melt, recover the liquid state and slowly flow back to the pores, and then came out again, this time condensed into a splendid palace with many red pillars, this is the Daming Palace of the Tang Dynasty ~ Then it showed the Kaifeng Mansion of the Song Dynasty, the ruins of the Yuan Dadu, the Forbidden City, due to the Qing Dynasty, the royal palaces of the Ming Dynasty are in the Forbidden City, in order to highlight the characteristics of the Qing Dynasty, the yurt is displayed, and finally Tiananmen Square is displayed. At this time, the venue was already a pile of applause.

Xiao Tao said: "What I just showed you is sequential playback, it can also be random, you can casually say a year or dynasty, or the people of the dynasty, events, etc., and it will show the buildings of the corresponding era by itself." Everyone began to experiment, one said Qin Shi Huang, and sure enough, the Qin Palace was displayed, and the Anshi Rebellion was displayed, and the Daming Palace was displayed...

In fact, if the technology is strong enough and the materials are hard enough, it is not impossible to degrade the aircraft and tanks into a liquid state and store them in a portable container.

At this time, the sound of chirping floated into Xiaotao's ears...

"Who is this? Engage in such a big battle. ”

"Hmph, my classmates, I'm very capable."

"I'm still wearing sunglasses, it's really good to pull."

"Well, it's not, you don't usually talk to us, proud of it~"

Xiao Tao was speechless, and said in his heart: "It's really a woman who tops 500 ducks, and there should be thousands of ducks over there now." Then she looked at Leng Ruoyi and swallowed her saliva, she suddenly wanted to drink the duck soup made by Leng Ruoyi~

Leng Ruoyi turned his head slightly and said something to the boy next to him, and then the boy took out a work card with a blue rope from a biodegradable bag, approached Xiao Tao, handed the document to Xiao Tao, and said:

"You're welcome to join the student union, go back and fill in your name."

Xiao Tao took it in a daze, and the sound of chirping sounded in his ears again.

Leng Ruoyi suddenly said, "You're okay here, let's go and see it together." ”

Xiao Tao looked up at Leng Ruoyi, who was talking to her, and then saw the rest of the student council members making way for her at the human wall...

In this way, Xiaotao also became a member of the human wall that guarded Leng Ruoyi... After seeing a few uncreative exhibits, I came to a classmate who drew to Japan, and this student made a cherry tree more than 1.8 meters high, the trunk, the branches are plastic, the cherry blossoms on the branches are silk, and the better thing is the falling petals, which are not on the ground, they are all still in the air. I saw that there can be thousands of pink and white petals suspended under the tree, from front to back from top to bottom, left, left and right, as if the falling cherry blossoms were frozen instantly, which is made of a gel that can be suspended in the air, the maker is a shy boy, the idea is very delicate, just to let everyone can clearly take pictures of the falling cherry blossoms, many people ran in to take a group photo~

walked forward again and came to Lili, who smiled at Xiaotao and gave her a thumbs up. Immediately started his own performance, Li Li took out a thin piece of black and red flakes, put it on a plate filled with liquid, and put it in a microwave oven, and then the microwave oven began to rotate, and the air was filled with the fragrance of black pepper beef tenderloin, and after a minute, Li Li took out the plate, and many people, including Xiao Tao, couldn't believe "wow", stared wide-eyed, and the plate was a piece of delicious and juicy steak!

"How did you get it?" Xiao Tao pounced over and asked.

Lili said proudly: "The thin slice is an American steak that has been processed and compressed, and the inside of the microwave oven is made of superconducting wire, and after the electricity is turned on, the superconducting wire reaches a certain temperature, and the cells in the beef are activated, and it is restored~"

Everyone was amazed~ Xiao Tao ate a few bites of steak and continued to walk with Leng Ruoyi.

There is also a small Tao in the back of the exhibit, which is a model of the British Big Ben, part of which is transparent, and you can see the device inside, which simulates the Penrose ladder, a small mechanical marble jumps on the stairs, jumping up one by one, and finally returns to the original point, look closely, one of the stairs moves down when the marbles come, so it uses the optical illusion of people.

In the end, after reading all the exhibits, Xiaotao became the only child who was elected to the student union, and was called to the conference room after school that day.
