Jia Yan felt that after the muscles that controlled his wings seemed to appear the color of a blue substance when he exerted force on them, his flying speed suddenly increased like an explosion!

For a moment, Jia Yan only felt an incredible gravity pulling him backwards. The speed was so powerful that he felt a force dozens of times his body weight!

If this kind of increase were experienced by a human being, the person might die directly because the blood is squeezed, and all the blood vessels will burst!

Only an astronaut's physique and a series of protective measures can withstand such a huge afterburner!

Just when Jia Yan exploded and wanted to see if his guess about the blue substance was correct.

At this time, a scene that Jia Yan could not even imagine appeared!

Bang!

A huge sound sounded.

A circle-like thing appeared near Jia Yan's compound eye.

Jia Yan only saw it for an instant, and then the circle-shaped smoke formed a ring from near his body, and then quickly dissipated in the air!

"Uh! This is a sonic boom?! So, I have broken through the sonic boom now! How is that possible!" Jia Yanfu's eyes were full of disbelief.

To break through the sound, the time must reach about one thousand two kilometers to pass the sound. If an individual passes through the sound, the sound must be very violent. At the same time, under certain weather conditions, the water vapor in the surrounding air will be compressed.

Let the sonic boom cloud appear in the air!

A few days ago, Jia Yan started to mutate and used the power of the mutation to start an air battle with two fighter jets. At that time, his limit speed reached 850 kilometers. Although it was already extremely fast, it was still far away from the breakthrough sound.

One thousand two hundred kilometers is still far away.

But I didn’t expect that after completing the mutation this time, I would directly break through!

And he felt that his wings did not exert much force, but reached the current speed very easily!

I was just trying to see if I could induce the azure substance. Unexpectedly, I accidentally broke through the sound!

To be continued.
Chapter completed!
