Jiang Kai and his group of four immediately spotted a sphere emitting a strong white light, bouncing around inside the cave.

The sphere seemed almost sentient, and upon hearing Jiang Kai's intention to catch it, it accelerated rapidly, darting toward the rock wall.

Hu Yan was closest to the light sphere, but it was too fast. He could only watch helplessly as it zipped past him.

With a loud bang, Hu Yan heard a crash behind him, followed by a piece of rubble hurtling toward him.
