30 The Powerful Speed-type Boss, the Freeze Bird!

Liu Yan's expression was solemn as he looked at the situation in front of him and kept thinking.

Logically speaking, the puppets should have an energy core, otherwise, they would not be able to operate at all.

However, he had just tried shooting every part once and had almost broken the puppets. The puppets were already riddled with holes, yet they were still moving.

At this moment, the surrounding ground was about to collapse.

If this continued, he and his wolf would be in danger.

Where else could the energy core be? It couldn't be in the sky, right? Liu Yan was getting annoyed.

However, at this moment, he sensed that something was wrong.

Previously, he had not paid much attention to the sky. After all, the sky was also full of ice, and there was nothing worth paying attention to.

But now, the temperature had risen yet the ice in the sky had not melted. Something was not right.
