"What is this?" Chen Xuan said confusedly.

"Hey......

The next moment, the member of the Science F4 grinned and said proudly: "I have installed a miniature vector propulsion power system in the body! And the energy source of this power system is this groove!"

"Just put this thing in my hand and put it in that groove and the bike will have amazing power in an instant!"

"If the calculation is correct, then the limit speed of this bike can probably burst to the level of supersonic speed!"

"How's that? Isn't it stunning? It's faster than many planes!"

After hearing this, Chen Xuan was naturally dumbfounded.

He never imagined that the ability of Science F4 in science and technology would be so strong......

In just two days, I was able to get a bicycle alive to such an incredible extent!

Amazing!

"It's really kneeling for these tech nerds!" At this moment, Chen Xuan's face was only a capital "suit".

Of course, in addition to shock, Chen Xuan's heart also had indescribable relief.

Because in any case, Science F4 is his registered disciple.

Then, in the future, if his Sunny Sky Martial Arts Hall needs scientific and technological support, Science F4 is bound to be of great help!

"Registered disciples, also disciples! The four of them are so good, when the time comes, we must get them all to the hall to help! My Sunny Day Martial Arts Pavilion is a science and technology martial arts hall after all, and what is lacking is this kind of talent......

Chen Xuan was thinking about the future, and the previous member of Science F4 had already taken out a strange luminous object from his arms with a smile.

The luminous object, somewhat resembling a thick ring, looks just right to fit perfectly into the groove under the seat cushion.

"This is the micro-arc reactor I developed, a super powerful power source!"

After a few moments, the member of the Science F4 was full of joy and said, "I'll put it on for you now!"

"Don't, don't. Although he admired Science F4 greatly, Chen Xuan hurriedly stopped it at this moment, "If you really get a thruster to go up, then our family Qingqing is cheating! This is not good, it really is not good!"

In Chen Xuan's view, by modifying the bike itself, Qingqing can ride faster and easier...... None of this is a problem, and he is more than happy to do so.

However, if you get the micro-arc reactor up, then this bicycle will lose the essence of a "bicycle"!

This kind of cheating, Chen Xuan naturally wants to refuse.

After all, Qingqing's competition is more about experience, not about earning the first place!

"Huh, don't you pretend?"

Seeing that Chen Xuan's attitude was extremely resolute, the scientific F4 member did not force it, but still handed the reactor to Chen Xuan's palm: "Okay, then don't install it for the time being!

"That's fine!"

After taking it briskly, Chen Xuan said again: "Four, thank you really this time!"

"You're welcome!" Science F4 immediately said in unison, "Master Chen, don't forget what you promised us before, you will teach us martial arts after a while, and you are not allowed to scold us!"

"Don't worry! I'm at No. 17 Yuanhua Street, and you're welcome to come over at any time!" Chen Xuan solemnly promised.

"By the way, give this to your daughter to put on. At this time, Xiao Qi handed over a wireless Bluetooth headset, "Today's wind is a bit strong, so we have to teach your daughter how to overcome wind resistance to the maximum extent during the competition, so as to save energy." ”

"Good drop!" Chen Xuan happily took it, "Then I'll go first!"

............

......

About 10 minutes later.

The teachers and students of Chunzhu Kindergarten and Golden Sunshine Kindergarten finally arrived at the shore of Crescent Lake under the transportation of more than ten buses.

At the same time, there were naturally a lot of media staff, parents and many onlookers!

You must know that this "Shuangyuan Lake Bike" competition is jointly organized by the Warriors Association, the Environmental Protection Association, and the Health Association!

The attention it has received is extraordinary!

Jiangzhou Satellite TV and major online live broadcast platforms all sent special personnel to the scene to conduct live broadcast reports.

In order to ensure the effect of the picture, various media parties have arranged helicopters over Crescent Lake to conduct aerial photography.

In short, this "Shuangyuan Lake Cycling" competition has attracted the attention of all walks of life in Jiangzhou, and it is of great significance!

"Qingqing, this is the super bike that the four uncles built for you the day before yesterday. ”

When he came to the location of the primary 07 class and found his baby daughter, Chen Xuanwei smiled and said, "You will ride it for a competition later, come on!"

"Chen Qing's father. The little guy didn't have time to speak, and Song Yuan, the head teacher on the side, saw this, but couldn't help but remind him directly, "Your bicycle doesn't have protective wheels, Qingqing will fall! No, Qingqing can't ride this to participate in the competition, it's too dangerous!"

"Teacher Song, don't worry, my bicycle is very special! It is like a tumbler, it will never fall!" As soon as the words fell, Chen Xuan demonstrated leisurely.

I saw him tip the bike over with a little force, and after only a few moments, the bike had magically regained its balance!

"Wow! this bike is amazing, and so is the poop!" the little guy smiled instantly, full of pride and joy.

As for Song Yuan, she was naturally surprised: "Ah?

............

The previous small demonstration undoubtedly attracted the envy of many children present, and many parents proposed to buy Chen Xuan's bicycle.

However, Chen Xuan politely refused one by one.

This is for the baby daughter to participate in the competition, and he won't sell it if he is killed!

"Students participating in the competition, please get on your bikes and follow the teacher to the starting point. ”

After gathering her thoughts, Song Yuan glanced at her watch and commanded in a loud voice.

In this way, the 15 children who signed up for the competition in the Primary 07 class, including Chen Qing, soon gathered towards the starting point under the leadership of Song Yuan.

"I hope Qingqing can have fun today. The corners of his mouth rose slightly, and Chen Xuan muttered leisurely in his heart, looking forward to the upcoming bicycle race.

"New mission refresh successful!"

Suddenly, a systematic prompt sound sounded in Chen Xuan's ears.

Immediately after, in Chen Xuan's mind, a line of eye-catching text appeared-

Current available tasks: Within a week, master a life skill and reach the [Mastery] level, and after completing it, you can obtain the technological object [Body Optimization Bed].

"A new mission is coming?"

Chen Xuan immediately perked up, and at the same time, he was extremely curious, wanting to know what kind of magical function the so-called "body optimization bed" had.
