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

The speed training ground uses a 3,000-meter circular runway.

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

The outer runway is sloping and even vertical at the outermost, making it look like the runway markings are drawn on the wall.

In fact, when the speed soars to a certain level, you are running on a circular wall, eliminating the need to slow down due to turning.

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

"Chen Xingjie, do you want to be together?" Guo Xiaofeng warmed up and beckoned to Chen Xingjie.

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

The corners of Chen Xingjie's mouth twitched twice, and said, "No need, you run, I'll take a look first." ”

He is still hitting 400 kilometers per hour, how can he play with two impact supersonic speeds?

He runs one lap and the other two can run three laps.

This kind of team can deal 10,000 critical damage to his young mind.

So he decisively returned to the speed booth and sat in a chair as a spectator.

"Are you ready?"

Analyst Chen Likun held up the speedometer and asked loudly.

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

"Three, two, one, run!" Chen Likun counted down three seconds and shouted the starting order.

Every time he recited a number, Fang Yuan and Guo Xiaofeng activated a speed ability.

When the word "run" is exported.

The two of them burst out with all abilities and shot out at the same time.

It was like two disemboweled cannonballs, blasting out at the same time, rolling up a tornado and almost tearing off Chen Likun's hair.

Both are very fast, and their ultimate speeds are already approaching the speed of sound.

Guo Xiaofeng was one position faster, and rushed to the wall runway first.

In the speed measurement training ground, the pipe rushes to the wall and the runway is called "going to the wall".

At the beginning, the wall runway still has a certain inclination angle, and the faster the speed, the higher the height of the wall, and the more vertical the wall.

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

Fang Yuan also followed up the wall, and the "Star Energy Turbo Aerodynamic" combined with the suit boost, bursting out of the extreme speed.

The two of them maintained a position gap, running wildly on the wall runway, standing in the speed measurement booth and watching, it was very shocking.

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

Because he can't get up the wall yet, he can only run on a 45-degree inclined track.

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

The speed of both men is already close to the speed of sound, so it only takes 9 seconds to run a 3km lap.

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

"Limit speed 1195, 1192, start to touch the sound barrier, continue!."

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

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

When the sound barrier is touched, the body moves forward, squeezing the air in front of it, causing the pressure to surge, and a shock wave is formed.

Shock wave is a technical word, and it has a similar meaning to shock wave.

In fact, the explosion was caused by a sudden spike in air pressure and a sudden expansion.

A sonic boom is the sound of a shock wave causing a bang.

If it's a sonic boom caused by an airplane, the sound is very scary and can shock some small animals to death.

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

The sonic boom caused by the fist is also very loud, but the simple sonic boom of the fist is actually not very powerful.

In real life, sonic booms can also be seen.

When the long whip is shaken and whipped, the "snap" sound of the whip tail is actually a sonic boom.

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

An airplane triggers a sonic boom that shatters glass.

Because the mass and volume of the aircraft are very large, under the intersection, the mass and volume of the person are relatively small, even if the sonic boom is triggered, the sound of the sonic boom alone will not form a very large force.

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

Both of them reached speeds of more than 1,191 km/h, and both touched the sound barrier.

When the sound barrier is touched, the initial shock wave begins.

Since the speed of sound is not breached, the shock wave vibrates violently.

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

After shaking violently, his speed will immediately slow down a bit.

Every time he sped up the speed, after touching the sound barrier, his body shook violently, and the speed slowed down again.

I went back and forth many times, but I couldn't break the sound barrier.

The sound barrier is like a barrier to speed, as long as you can't rush through, you will be blocked under the speed of sound.

Therefore, the distance between the two people can never be opened, just one position away, even if they are separated by a short distance, after touching the sound barrier, they will quickly close.

Analyst Chen Likun continued to stand on the side of the runway, and began to shout three seconds in advance: "1195, 1193, just a little bit, work harder!" ”

After he finished shouting, he walked back to the speed measurement booth and said to Admiral Rhodes: "General, you said that these two people, who can break through the speed of sound first?" ”

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

Due to the presence of sound impairment.

If there is only a theoretical speed of 1224 km/loss, it cannot break through the speed of sound, and it must exceed a certain amount of this number to break through.

Otherwise, after touching the sound barrier, the body shakes violently, and the speed will be slowed down immediately.

After running more than two dozen laps.

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

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

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

Chen Likun imported the data into the software and calculated the answer: "At present, it is 115.3%, an increase of 0.2%, and the speed of progress is very fast." ”

When Fang Yuan was chatting with Professor Yang Yuping before, he had heard him say that the Star Power cultivation model had an effect on all cultivation that used Star Power.

Therefore, theoretically, the "Lightning Speed" also consumes star power, and if you use the war-level star power cultivation model to cultivate, the "Lightning Speed" will also grow together.

It is true that you can break through the speed of sound with simple training, but it may take many days of training to do it.

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

That is, let the "lightning speed" grow up first.

So, copy the "Lightning Speed" and use the "Lightning Speed" and "Lightning Speed (Mimicry)" together.

When used together, the same abilities don't double speed, but they do cost twice as much power.

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

What Fang Yuan wanted to do now was to test whether this method was feasible.
