Underground Prison

*Crack!*

*Crack!*

One deep crack after another started to form on the surface of the boulder.

Under a few seconds, hundreds of cracks were visible around the stone, making it to look like it was covered with huge spider webs from all angles.

Seeing this sight, Greg started to smile slightly and with a powerful motion, he pulled his hand out of the gap.

*BAM!*

With a loud explosion, the huge boulder erupted into several small pieces, revealing a small entrance like a gap on the ground instantly.

"It seems it has been opened.", said Greg and looked at the broken orb in his hand.

The moment he used his power to examine the interior of the boulder, he was quite surprised to find an orb inside it, which was swirling here and there without stopping.

After analyzing it for a while, Greg realized that the orb's path was following a system and was not random.
