Dad’s Science and Technology Martial Arts Museum

"Competition? Martial arts competition?" Lei Mai asked casually, without any emotional fluctuations due to the identity of the opponent.

The reason is very simple. Shi Ming, the president of the Jiangzhou Martial Artist Association, has been with him for many years and has a very good relationship.

Think of the Thunder Vein back then, but he was the most dazzling genius in the Jiangzhou martial arts world!

At that time, Shi Ming was also a very strong genius, and he practiced in the same martial arts hall as Lei Mai.

Therefore, the two have a strong personal relationship, and Shi Ming often seeks advice from Lei Mai, which has benefited a lot.

Until now, Leimai is the "big brother" that Shi Ming respects the most. During the festivals, he will always find Leimai to gather together and recall the past.

"It's not a martial arts competition, it's just a children's bicycle competition."

Shi Ming smiled and replied, "My three vice presidents also have important things to do today, so I thought about it, and only you, Brother Lei, can represent me!"

"Brother Lei, can you help me? It's very relaxing to just sit on the rostrum for a morning."

After hearing this, Leimai hesitated for a moment before replying, "Okay."

"Thank you Brother Lei!" Shi Ming on the other end of the phone said repeatedly, "I'll send my secretary to pick you up right away!"

"Um."

After hanging up the phone, Leimai quickly calmed his mind and thought to himself: "It seems that I can't go back to the museum to see the teacher until noon today..."

…………

After half an hour.

Yuanhua Street, the gate of Sunny Day Martial Arts Hall.

"A day off?"

The three of Xu Mang, who arrived at almost the same time, looked at the note attached to the door, looked at each other, and then showed helpless smiles.

"The teacher is definitely going to play with the younger sister again!"

"Let's go back to sleep at ease, our teacher is simply a model of not loving the country and loving the girl!"

"Chuhuhu, since the teacher decided to close the library to play with her daughter, then ten cows can't be pulled back!"

Soon, after "spit out", the three people who knew Chen Xuan's personality well chose to leave without hesitation.

"Ah!"

At the same moment when the three disciples "spit out", Chen Xuan, who had just arrived by the Crescent Lake, couldn't help but sneezed.

"It's too windy in the morning? I have a cold? Shouldn't it be..." Chen Xuan raised his brows slightly, muttering secretly, "So, is someone missing me?"

Chen Xuan, who was muttering while walking, arrived at the sunset pavilion, the place agreed with Science F4.

"Uh, the four of you, won't you stay overnight?" Chen Xuan was startled when he saw Science F4 again.

I saw the scientific F4 at this time, and all of them had dark circles under their eyes. At first glance, it was caused by staying up late.

"The time is too tight, we didn't sleep for two nights, just to get the bike you asked for!"

Shaking his head, Xiao Qi invigorated his spirits, and then his eyes signaled Chen Xuanchao to look aside: "Well, look! Fortunately, it was not humiliated, we finally made it!"

Chen Xuan hurriedly looked sideways, only to see a strange-looking bicycle not far away.

What surprised Chen Xuan the most was not its appearance, but the fact that this bicycle stood upright on the ground strangely, without any support, but it could maintain its balance!

No matter how the lake wind blows, there is no way to blow it down.

Because of a slight tilt, the bike will automatically regain its balance after a while!

"This... what's going on? Why won't it fall?" Chen Xuan felt extremely curious.

"This is what I designed! I have a built-in balance system in the front wheel of the car, and the rotation of the flywheel in the control center can produce a gyroscopic effect to keep the bike permanently balanced." In the scientific F4, the chubby man suddenly Proudly explained, "So, whether it's stationary or moving fast, it will never tip over!"

"Is the balance system installed? Will this car be very heavy?" Chen Xuan asked worriedly.

After all, if the body is too heavy, it will be very difficult for Qingqing to ride, so it will definitely have a big impact on the final result.

"You can try!" A tall and thin man said proudly in Science F4.

Seeing that the tall and thin man was extremely confident, Chen Xuan hurried over to see how the car weighed.

"Why, how can it be so light?"

With a little effort, Chen Xuan picked up the bicycle with ease, and couldn't help exclaiming.

According to his estimation, the total weight of this car may not exceed 3 kilograms!

"The main body of the car body is the lightest microlattice material in the world today. I made it with a 3D printer in my research center!" The tall and thin man introduced proudly, "As for other fixed connection devices, etc., Hey, it's all made of special titanium alloys!"

"Basically, it's the lightest bike in the world!"

After listening to it, Chen Xuan suddenly realized that he admired this science F4 even more.

"These science nerds really have two strokes!"

While sighing in his heart, Chen Xuan carefully observed this strange-looking bicycle, and finally couldn't help asking: "Why does it look a little different from other bicycles?"

Of course, this is just Chen Xuan's conservative statement.

In fact, is this bike more than a little different? That's a big difference!

The overall body, including the front and rear wheels, is very narrow and thin, very sleek everywhere, and has a strange appearance.

The most peculiar thing is that it doesn't even have a bicycle chain!

If it hadn't still had two pedals, Chen Xuan would have wondered if Science F4 had made an electric car...

Hearing Chen Xuan's question, Xiao Qi suddenly regained his energy and quickly explained: "The appearance of this car is all a streamlined design that I have researched according to the ideal aerodynamics! This kind of design can maximize the Compared with those bicycles, it saves dozens of grades of effort!”

"Originally, I wanted to install a device that absorbs wind resistance and converts it into power, but it was too heavy and troublesome, so I didn't think about it."

As soon as Xiao Qi's words fell, Chen Xuan gave a thumbs up to Science F4 and repeatedly praised: "Cow! You guys are really awesome! I believe my family, Qingqing, will get good results when riding this bike!"

"and many more!"

At this time, the last member of Science F4 said anxiously: "Master Chen, I have made a great contribution to this car, you can find it quickly and praise me!"

"Uh... your contribution? Where is it? I don't think I found it!" Chen Xuan frowned slightly.

"The seat cushion! Under the seat cushion!" The member replied repeatedly.

Hearing this, Chen Xuan immediately squatted down and looked up at the seat cushion.

I saw that there was a circular groove under the seat cushion, as if something could be put in it.
