Audience Salted Fish: "My day!" ”

Yin Xiaofei's think tank: "! ”

Including Lao Tang, he almost stared out his eyes, and the whole person was almost on the screen. He looked at Shi Tiexin, who was spiraling down but walking on the ground, his mind was blank, and he trembled his lips and muttered unconsciously: "Impossible...... That's impossible...... His bullet legs...... His bullet legs ......"

As mentioned earlier, the big loop is divided into two sections. If you go down from the top, the first stage is a spiral rappel, and the second stage is the heaven and earth loop.

Due to its diameter, angle, and deflection rate, there is an optimal solution for landing geometrically. As long as the speed of this optimal solution decreases, a balance can be achieved between centrifugal, centripetal, friction, and gravity, and the most labor-saving and stable attitude can be achieved.

This speed is the safest speed for the downhill spiral, and the number eight is probably around this speed.

But if you want to get faster, it's not easy.

The farther you deviate from the theoretical speed, the more difficult it is to control.

If you don't have enough speed, you will fall, and if you are too fast, you will be thrown out. And Shi Tiexin directly overtook the eighth, and there were even a lot of overtakes, and the layman looked lively, and the well-informed old Tang was stunned.

This means that Shi Tiexin has a high attainment in physics and mathematics - at least at the level of foundation. At the same time, it also represents that Shi Tiexin has approached the level of "perfect fire" in terms of basic leg work.

Lao Tang was stunned and watched Shi Tiexin land quickly, and in the blink of an eye, he sped out of the downhill spiral, without a trace of reluctance.

Mu Ran's face finally turned to horror: "His bullet star legs...... At least it's profound! ”

"He's only been practicing for a few days?!"

In a blank brain, Lao Tang only felt that a picture suddenly flew in front of him in a trance. That was when Shi Tiexin signed up for the competition, the moment when he exchanged the bullet star legs.

At that time, I disdained the belly slander.

But now, Lao Tang looked at Shi Tiexin in a daze, and a title involuntarily appeared in his mind - genius! No, this word is no longer enough, it should be a martial arts wizard who is unique in ten thousand!

"The brightest star ...... in the night sky" Lao Tang couldn't help but muttered a description of the star's legs, he watched Shi Tiexin rush into the circle of heaven and earth, swishing and climbing rapidly, and his eyes did see a shining star in a trance.

But in Yin Xiaofei's headquarters, those "masters" were nervously and maliciously looking forward to what was about to happen.

Yes, this is it, this is your peak, and then, let me fall into the abyss.

Your vehicle is about to crash!!

Whoosh, under the bated gaze of countless people, Shi Tiexin flew over to the apex of the Great Loop.

At this moment at the apex, Shi Tiexin raised his head and looked at the completely repeated earth below, and his heart was quite interesting and peaceful.

In the next moment, the angle between the earth and the line of sight expanded rapidly. Grunt, the wheels accelerate wildly, the axles spin wildly, and all the mechanical energy is converted into kinetic energy. Tremendous pressure squeezed the tires, axles, frames, and transmissions, creaking, and a moaning of overwhelming weight seemed to be coming from the shock absorbers.

"Crash, crash ——!" The "masters" had blood-red eyes, and they were extremely looking forward to the ending that would make them comfortable. And Shi Tiexin, as they expected, rushed straight to the bottom of the loop without slowing down, which is the point where the frame is most stressed.

And then.

Whoosh - at a speed of one hundred and nineteen per hour, the stone iron core rushed straight out, and the whole car was firm and sturdy without reluctance.

Boom!

Shi Tiexin slapped the crystal ball, and the fourth general was imprinted in his hand. Without a trace of slowdown, Shi Tiexin rushed straight to the location of the fifth crystal orb.

"How is that possible!" The "masters" were all dumbfounded and stunned. Poof, the guy who had just sworn by him sat down in his chair all of a sudden, his eyes straight. His mind was quickly filtering the information of Shi Tiexin's vehicle accessories, and he couldn't figure it out. Why was it possible to ride a bicycle that should have reached the limit early in the morning?

This is the third of the five things Shi Tiexin has done in the past few days.

Change the car!

How can a person who can't change his own car claim to be a mature driver?

Shi Tiexin's perfect-level mechanical modification technique exerted its power and changed the assigned car from beginning to end. Time is limited and the budget is insufficient, so there is no way to make a comprehensive change. But only in terms of solidity and reliability, Shi Tiexin can be said to have changed this car to the extreme.

In the midst of the hurricane, Shi Tiexin can still sense the condition of the car with his driving skills and modification skills - very good, there is no problem at all.

Then, I will be able to gallop boldly.

"Ladies and gentlemen! Ladies and gentlemen! The match just now was really thrilling, and the No. 9 and No. 10 players both showed extraordinary strength and successfully passed the first three levels. Among them, the performance of the No. 10 player is the strongest. Let's take a look at the personal time, and after the three levels are cumulative, the No. 10 player saves 3 minutes and 17 seconds compared to the No. 9 player, which is the fastest player so far! ”

"There's no doubt that the number 10 has a lot of explosiveness. So in the face of the fourth level, can the No. 10 player maintain his form and show his style in stamina? Let's look at a piece of advertising. ”

Don't blame the host for inserting ads, the key is that the fourth level takes a long time.

The fourth level is easy to say and difficult to say, but the level setting of this level itself is very simple and clear, and the location of the crystal ball is also very clear.

It's far away.

How far away?

As far as Beicheng District.

That's right, competitors need to start from Uptown, ride all the way to Northtown, and then shoot the crystal ball at a special location.

The No. 8 just now was frightened after Shi Tiexin overtook him, and he was out of breath, and finally fell off the loop and hung on the southeast branch. There are only three people still competing.

Yin Xiaofei was pedaling hard, and she was already out of Shangcheng.

"I knew that kid wasn't that easy to deal with." Yin Xiaofei glanced back, as if looking for Shi Tiexin's figure. She then hooked up the transmission to the highest gear ratio and cruined the northern city in the most effortless way.

I can't say it, but I have to use some tricks again. It's just that I have prepared two kinds of front and back for this external move, hoping that the first one can get the kid, otherwise I can only go to the second one.

The masters of the think tank comforted each other: "Sister Xiaofei, that kid's endurance will definitely not work." ”

Yin Xiaofei just sneered and didn't listen to these again.

On the other side, a certain son couldn't help but want to touch his face for the third time. Stamina? The endurance of the animal has always been as strong as that of a brute. But what really made him care was the incredible Bullet Star Leg cultivation realm.

The invisible man didn't even say hello, and suddenly disappeared again, speeding away in the direction of Shi Tiexin at high speed.

He was going to look at the boy up close with his eyes.
