"What stuff is this?" Chen Xuan asked in confusion.

"Hey..."

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

"As long as I put this thing in my hand into that groove, this bike will instantly have amazing power!"

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

"How's that? Isn't it awkward? Faster than many planes!"

After hearing this, Chen Xuan was naturally dumbfounded.

He never thought that the scientific and technological capabilities of the F4 Science are already so strong...

In just two days, he has made a bicycle so unimaginable!

be amazed!

"I really knelt for these technology houses!" At this moment, Chen Xuan's face only had the word "serve" in capitals.

Of course, apart from shock, Chen Xuan's heart also has endless gratification.

Because anyway, Science F4 is his registered disciple.

Then, if his Sunny Day Budokan needs technical support in the future, Science F4 is bound to be of great help!

"Named disciples are also disciples! The four of them are so awesome. When the time is right, they must all be brought to the museum to help! My Sunny Day Budokan is a science and technology martial arts museum after all, and what I lack is this kind of talent..."

Chen Xuan is thinking about the future, and the previous member of Science F4 has taken out a peculiar luminous object in his arms with a smile.

This luminous object is somewhat similar to a thick ring, and it seems to fit perfectly into the groove under the cushion.

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

After a while, the science F4 member said cheerfully: "I will install it for you now!"

"Don't don't don't." Although I am impressed by the scientific F4, Chen Xuan hurriedly stopped at this moment, "If we really get a propeller to go up, then our family Qingqing will be cheating! This can't work, really can't!"

In Chen Xuan's view, by transforming the bicycle itself, Qingqing can ride faster and easier...All of these are no problem, and he is very happy.

But if the micro-arc reactor is put up, then this bicycle loses its essence as a "bike"!

This kind of cheating, Chen Xuan naturally refuses.

After all, Haruharu's competition is more to experience, not to earn the first place!

"Huh? Don't you pretend?"

Seeing that Chen Xuan's attitude was extremely determined, the scientific F4 member did not force it, but he still handed the reactor to Chen Xuan's palm: "Okay, then don't install it for the time being! But, take the micro arc reactor well, maybe God you can use it!"

"no problem!"

After    happily accepted, Chen Xuan said again: "Four people, thank you so much this time!"

"You are welcome!" Science F4 said in unison immediately, "Master Chen, don't forget that you promised us before. You will teach us martial arts later, and you are not allowed to scold us!"

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

"By the way, give this to your daughter to wear." 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 maximize Overcome wind resistance so that you can save energy."

"Good drop!" Chen Xuan Xinran took it, "Then I'll go one step ahead!"

…………

……

About 10 minutes later.

The teachers and students of Chunsun Kindergarten and Golden Sunshine Kindergarten finally arrived at the Crescent Lake by more than ten buses.

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

You need to know that this "Shuangyuan Lake Cycling Tournament" is jointly organized by the Warrior 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 dispatched special personnel to the scene to carry out live coverage of the whole process.

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

In short, this "Shuangyuan Lake Cycling Competition" has attracted attention from all walks of life in Jiangzhou. It is of great significance!

"Qingqing, this is the super bike specially built for you by those four uncles the day before yesterday."

came to the position of the small 07 class. After finding the baby girl, Chen Xuanwei smiled and said: "You will ride it for the race later, come on!"

"Dad Chen Qing." Before the little guy had time to speak, Song Yuan, the head teacher on the side, couldn't help but directly reminded him, "Your bicycle does not have a protective wheel. Qingqing will fall! No, Qingqing can't ride this to participate. The game is 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 voice fell, Chen Xuan leisurely demonstrated.

saw him dump the bike with a slight force, and after only a few moments, the bike had magically restored its balance!

"Wow! This bike is amazing, and Baba is amazing!" The little guy opened his eyes and smiled instantly, full of pride and joy.

As for Song Yuan, she was naturally shocked: "Huh? Is this all right?"

…………

The previous small demonstration has undoubtedly attracted the envy of many children present, and many parents have also proposed to buy this bicycle of Chen Xuan.

However, Chen Xuan declined one by one.

This is for the baby girl to participate in the competition, he will not sell it to death!

"Students participating in the competition, please ride your bicycles and go to the starting point with the teacher."

After closing her mind, Song Yuan glanced at her watch, and then shouted.

In this way, the 15 children from Class 07, including Chen Qing, who signed up for the competition, 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. It can be said that he is inexplicably looking forward to the upcoming bicycle race.

"The new task refreshed successfully!"

Suddenly, a system prompt sounded through Chen Xuan's ears.

followed, a line of striking text appeared in Chen Xuan's mind——

Currently available tasks: within one week, master a life skill and reach the level of [Proficient], after completing it, you can get the science and technology [Optimization Bed].

"A new mission is here?"

Chen Xuan immediately refreshed, and at the same time he was very curious, wondering what kind of magical function the so-called "body optimization bed" has.
