University speeches have student unions that specialize in maintaining order, and Liu Hai handed over the list of materials written by Yang Fan to the officers of the student union and asked them to buy them.

I have to say that the people of the student union are still very efficient, and after about ten minutes, the people of the student union walked in carrying a large pile of iron, rubber and other materials.

Looking at the pile of materials in front of him, Yang Fan finally stood up, but the crowd began to discuss: "Sit and wait for high school students to make jokes." ”

"What nonsense! Can't you play us like monkeys?"

……

The crowd scoffed and kept shouting and scolding, and even Xiang Shan, Han Piao, Fang Hongtu and others frowned and shook their heads secretly.

At the same time, Yang Fan was already standing in front of a large pile of materials.

Yang Fan casually picked up a piece of iron and thought for a while, and said to himself: "Anti-gravity technology, as the name suggests, gets rid of the shackles of gravity. ”

"As for how to get rid of gravity, it is necessary to use the earth's magnetic field. ”

Yang Fan thought as he picked up a few more copper wires, and then quickly wound them around a piece of iron.

"The earth is a huge magnetic field, the north and south poles of the magnetic field, the magnetic field has both suction and repulsion, and if I want to really achieve anti-gravity, I have to use the repulsion of the magnetic field, as long as the repulsion of the magnetic field is greater than the weight of the car I developed, the anti-gravity car I developed can be suspended in the void to achieve complete anti-gravity. ”

As soon as Yang Fan started research and development, the whole person fell into it, holding an iron sheet in one hand and copper wire in the other, constantly winding out strange shapes.

"I can use electromagnetism to generate a magnetic field on the body of an anti-gravity car, and this magnetic field must be able to convert the positive and negative poles at will, so that I can convert the magnetic field of the anti-gravity car into a magnetic field that is the same as the earth's magnetic field, and the two magnetic fields will repel each other to achieve true anti-gravity technology." ”

"As for the energy source of the anti-gravity car, let's use the new energy button battery I developed earlier. ”

Yang Fan held a small wrench in his mouth, and his expression was focused on a large number of parts, and soon, a prototype of a pitch-black and shiny sports car with a streamlined structure had appeared in the sight of the crowd.

The appearance of this sports car looks very luxurious, just in appearance, it is not weaker than some of the current top sports cars, but the strange thing is that the prototype of the sports car made by Yang Fan has no tires.

Seeing this, the students in classroom 1201 gradually quieted down, although they didn't believe that Yang Fan could use anti-gravity technology, but after seeing the prototype of the sports car made by Yang Fan, they were still secretly speechless.

Even Xiang Shan, Han Piao, Fang Hongtu and others were stunned.

Fang Yan frowned even more, Yang Fan had been talking to himself in the process of building an anti-gravity car, maybe others couldn't hear it, but Fang Yan could hear it clearly because he was close.

Every word Yang Fan said was very professional, and more importantly, every time Yang Fan said a word, he would apply the technology contained in this sentence to the anti-gravity car he made!

If it is really as Yang Fan said to himself, maybe Yang Fan can really successfully develop an anti-gravity car!

Thinking of this, Fang Yan's expression couldn't help but become a little solemn.

At the same time, Lin Feiyan's live broadcast room has already been blown up by the barrage: "I'm Cao! Anchor, your friend is developing black technology again?!"

"This Nima, the name of the live broadcast room is actually called the live broadcast research and development of anti-gravity cars, I rub it, the anchor wants to go against the sky?!"

"Gravity-defying cars?!Anchor, are you sure you're not here to be funny?!"

……

The fans in Lin Feiyan's live broadcast room grew rapidly, and soon, the fans in Lin Feiyan's live broadcast room had increased to 200,000.

On the podium, Yang Fan is still concentrating on the research and development of anti-gravity cars, which is the first car after Yang Fan came to the world, so in terms of appearance and core technology, Yang Fan has put a lot of thought into it.

"Use the new energy button battery as its core energy source, create a freely changing magnetic field in the anti-gravity car, use aerospace materials, and titanium alloy as its body ......" Yang Fan muttered while holding the material and tinkering, after a while, Yang Fan finally took a deep breath, wiped the sweat on his forehead, and said with a smile: "Anti-gravity car, it's done." ”

The entire crowd in classroom 1201 had forgotten to speak, and the audience was silent, and everyone turned their eyes to the anti-gravity car in Yang Fan's mouth.

This anti-gravity car looks like a sports car, with a predominantly black color tone, a streamlined body and a very beautiful appearance, however, to the surprise of the crowd, this sports car has no tires at all, let alone an engine, but looks like a model.

"I'm Cao! This special thing is also called an anti-gravity car?! I don't read much, don't lie to me!"

"It's ridiculous! If it's a gravity-defying car, I'll eat it!"

……

After a long time, the crowd finally came to their senses, but most of the crowd was insulting Yang Fan.

However, Xiang Shan, Han Piao, Fang Hongtu and others frowned, although the anti-gravity car made by Yang Fan looked like a model, but some details of the anti-gravity car made by Yang Fan just now were fully seen by them.

When Yang Fan made an anti-gravity car, some of the technologies he used were not even understood by Xiang Shan, Han Piao, Fang Hongtu and others.

Fang Yan, who was closest to Yang Fan, frowned, just now Yang Fan was making an anti-gravity car, while talking to himself, if Yang Fan really did the same as what he said, then Yang Fan's anti-gravity car might really be able to be realized.

Yang Fan ignored the crowd, walked straight to the anti-gravity car, and said to himself: "The door of the anti-gravity car, I specially use facial thermal recognition technology, as long as I walk in front of the car, the car will automatically open the door." ”

Yang Fan's facial thermal recognition technology is similar to the facial recognition unlocking of mobile phones, but in comparison, Yang Fan's facial thermal recognition technology is still a little ahead, because even in the absence of light, facial thermal recognition technology can also recognize people's appearance, so as to open the car door.

"At the moment, only my appearance is recorded in the anti-gravity car. The corners of Yang Fan's mouth hooked up a smile, the anti-gravity car he developed only recorded his appearance, that is to say, in this world, except for Yang Fan, no one can open the door of the anti-gravity car.

Click!

Yang Fan calmly walked to the anti-gravity car, and then, the scissor door on the side of the anti-gravity car slowly opened.

The corners of Yang Fan's mouth hooked a smile, stepped into the cab of the anti-gravity car, and quickly controlled it in his hands, and then the scissor door of the anti-gravity car closed again, and the entire anti-gravity car slowly suspended under the shocked gaze of the crowd.
