Chapter 591: Ten Times the Speed of Sound!

Ten times the speed of sound!

The speed of sound was 340 meters per second and ten times that would be 3400 meters per second. Such a speed surpassed normal missiles or cannon shells. The person who attacked from afar must have known that Chen Fan could probe with his Soul Energy, so he launched that deadly attack from twenty kilometers away.

It took only five seconds for the spear to travel twenty kilometers.

"Bang!"

Before the piercing sound, the metal spear had already swept through the sky with a beam of blue electric light and was right next to Chen Fan in an instant. Even when it was still far away, Chen Fan had been able to sense its unbelievably high energy and incredible sharpness. It was a spear as powerful as Lin Shuming's Earth Level Deity sword.

"Boom!"

Right at that moment.
