Rumble!
At this moment, in the skies above the Celestial Cry Mountain Range, an extremely piercing sound of something cutting through the air echoed continuously, like tens of thousands of thunderclaps erupting at the same time, creating a scene of immense grandeur.
This was the sonic boom produced by Ye Chen and the Black Rhinoceros Great Demon during their high-speed flight.
The speed of both had far exceeded the speed of sound, leaving a trail of white air behind them.
However, the Black Rhinoceros Great Demon was noticeably faster than Ye Chen.
The distance between the two was rapidly closing.
After ten breaths, they had left the canyon far behind and arrived above a mountain ridge several miles away.
By this time, the distance between the Black Rhinoceros Great Demon and Ye Chen had shrunk to less than three hundred feet.
