In seven days, Xia Fei had killed an innumerable number of stone monsters. These stone monsters were all humanoids, with stones of various sizes forming their limbs, torsos, and heads. Flames of different colors constantly erupted from their bodies.

There were no longer any stone monsters in the center of the battlefield, but the thirteen stone pillars around suddenly began changing!
A vast and destructive roar came from the depths of the earth, and the ground shuddered as if it was going through a magnitude ten earthquake!
