章 587: Five Techniques in Full Release, Terrifying!

The hunchbacked old man's sword pierced into the white cocoon, but he found nothing.

The ghost-faced youth stood quietly behind him. His gaze was not cold, but indifferent.

"All five techniques have been activated. Martial artists are mortals! 

"The three forbidden techniques; like Gods and deities! 

"Now it seems that using five techniques to kill you is enough!"

An indifferent voice came from Skylar Neal's mouth.

Jamison Walsh's face was covered in cold sweat. He said hoarsely, "What a fast speed!"

"Speed? Have you ever heard a sonic boom?" Skylar's ruthless voice sounded.

At this moment.

Everyone was shocked.

"What?" Quinten Kelly was horrified.

"Sonic boom?"

Colson Morales could not believe it.

In order to produce such a sound, one had to reach the speed of sound.

The speed of sound was about 340 meters per second.

How could a martial artist possess such terrifying speed!
