The two stood on the track and began to do warm-up exercises.

The speed test training ground uses a three-kilometer circular track.

The runway is divided into an inner track and an outer track, and the inner track is a normal flat track.

The outer runway is inclined, and even vertical, and looks like the track markings are drawn on the wall.

In fact, if you reach a certain level of speed, you will run on the circular wall, eliminating the slowdown caused by turning.

As long as the speed is fast enough, people will not fall off the circular wall.

"Chen Xingjie, do you want to be with me?" Guo Xiaofeng waved to Chen Xingjie while warming up.

Before Fang Yuan came, Chen Xingjie was the only one who trained with Guo Xiaofeng.

Chen Xingjie's mouth twitched twice and said, "No need, you guys run away, I'll take a look first."

He is still hitting a speed of 400 kilometers per hour, so how can he play with two hit supersonics?

He ran for one lap, and the other two could run three lap.

This team can cause 10,000 critical damage to his young mind.

So he decisively returned to the speed test shed and sat in a chair as an audience member.

“Are you ready?”

Analyst Chen Likun held up the speedometer and asked loudly.

Fang Yuan and Guo Xiaofeng gave thumbs up at the same time, indicating that they were ready to be completed.

"Three, two, one, run!" Chen Likun counted to the countdown and shouted the starting command.

Every time he recites a number, Fang Yuan and Guo Xiaofeng activate a speed supernatural power.

When the word "run" is exported.

The two people had all their supernatural powers and shot out at the same time.

It was like two shells that were out of the bore, and they were bombarded at the same time, rolling up the tornado airflow, almost lifting Chen Likun's hair.

Both of them were very fast, and their limit speed was approaching the speed of sound.

Guo Xiaofeng was quicker and rushed to the wall runway first.

In the speed test training field, the pipes rushing onto the wall are called "up the wall".

At the beginning, the wall runway had a certain inclination angle. The faster the speed, the higher the wall height, the more vertical the wall surface.

Guo Xiaofeng took the lead in stepping on the wall track and began to lead the way.

Fang Yuan also followed the wall, and the "Star Energy Turbo Aerodynamic" combined with the help of the battle suit, burst out with extreme speed.

The two of them kept a gap in their positions, ran wildly on the wall track, standing in the speed test shed, and it felt very shocking.

There is no need to use a speed tester. Chen Xingjie only needs to look at the height of the wall track where the two of them are running, and he knows that these two are much faster than him.

Because he couldn't get on the wall, he could only run on the 45-degree inclined track.

Therefore, just look at the inclination of the runway you are on, and you can infer the approximate speed.

Both of them have approached the speed of sound, so it only takes 9 seconds to run a lap of 3 kilometers.

Chen Likun stood next to the runway, holding the speedometer, and shouted 3 seconds in advance before the two of them rushed over. Because the shouting was slow, it would take a long time to catch up with the two of them.

"The limit speed 1195,1192 begins to touch the sound barrier, continue!"

The speed of sound is 1224 km/h, and both of them are approaching the speed of sound.

Chen Likun continued to shout: "Continue to accelerate, touch the sound barrier and the speed is 1191 km/h, come on!"

After touching the sound barrier, the body moves forward and squeezes the air in front, causing the pressure to surge and a shock wave.

Shock wave is a professional word, which means similar to shock wave.

In fact, the explosion is caused by the sudden surge in air pressure and sudden expansion.

Sound boom is the explosion caused by shock waves.

If it is a sonic boom caused by an airplane, the sound is very terrifying and can kill some small animals.

However, the power of a sonic boom is related to the mass and volume of the object that triggers a sonic boom.

The sound boom caused by fists is also very loud, but the sound boom of fists is actually not very powerful.

In real life, you can also see sonic booms.

When the long whip is swinging and whipping, the "pop" sound from the tail of the whip is actually a sonic boom.

Because the whip tail is small in mass and small in size, although it causes a sonic boom, it sounds very harsh, but it does not have much power.

The sonic boom caused by the plane can shatter the glass.

Because the mass and volume of the aircraft are very large, when intersected, the mass and volume of a person are relatively small. Even if the sound boom is triggered, the sound boom alone will not form very powerful.

Fang Yuan and Guo Xiaofeng continued to run on the sloping wall track.

Both of them had speeds above 1191 km/h, and they both touched sound barriers.

When touching the sound barrier, initial shock waves begin to form.

Since there is no breakthrough in the speed of sound, the shock wave will vibrate violently.

Fang Yuan was behind Guo Xiaofeng's side and clearly saw that Guo Xiaofeng's body began to shake violently.

After violent shaking, his speed will immediately slow down a little.

Every time he rushes his speed, after touching the sound barrier, his body shakes violently and slows down.

I went back and forth many times, but I could never break through the sound barrier.

A sound barrier is like a barrier of speed. As long as you can't rush through it, you will be blocked from the speed of sound.

Therefore, the distance between the two people is always unhappy, and it is only one body position. Even if it is a short distance, it will quickly get closer after touching the sound barrier.

Analyst Chen Likun continued to stand by the runway, but started shouting three seconds in advance: "1195, 1193, it's just a little bit, work harder!"

After he finished shouting, he walked back to the speed test shed and said to Admiral Rod: "Admiral, who can break through the speed of sound first, do you think of these two people?"

"It's hard to say. According to the current situation, neither of them can break through today." Admiral Rhodes looked at the two people who were rushing on the runway on the wall and said with a plain expression.

Due to the existence of sound disorders.

If only the theoretical speed of 1224 kilometers/disappearance cannot break through the speed of sound, it must exceed this number by a certain amount before it can break through.

Otherwise, after touching the sound barrier, the body trembles violently and the speed will immediately slow down.

After running for more than twenty laps.

Fang Yuan slowed down and walked back to the speed test shed.

Guo Xiaofeng continued to run, hoping to break through the shackles of sound barriers as soon as possible through hard training.

Fang Yuan walked back to the speed test shed and asked, "How is it? How efficient is the 'Lightning Speed'?"

Analyst Chen Likun imported the data into the software and calculated the answer: "It is currently 115.3%, an increase of 0.2%, and the progress is very fast."

When Fang Yuan was chatting with Professor Yang Yuping before, he heard that the Star Power Cultivation Model has an effect on all cultivation using Star Power.

Therefore, in theory, "lightning speed" also consumes star power. If you use the war-level star power cultivation model for practice, "lightning speed" will also grow along with it.

Simply persisting in training can indeed break through the speed of sound, but it may take many days to train.

Fang Yuan thought about it and thought of a faster way.

That is to let "lightning speed" grow first.

Therefore, the "Lightning Speed" was copied and the "Lightning Speed" and the "Lightning Speed" and the "Lightning Speed ​​(Miscellaneous)" were used together.

These two identical abilities will not double the speed increase, but the star power consumed will be doubled.

Theoretically, the growth of "lightning speed" will also double.
Chapter completed!
