At first, Zach didn't know why he could suddenly feel himself being pulled away from the twelfth floor. But then he noticed that the feeling stemmed from the center of his chest. It was thanks to his world essence energy.
The next moment, Zach, Nora, Alzara, and Borso found themselves on the thirteenth floor. The others were a little confused but quickly adapted. The thirteenth floor was another desert, one that hadn't been turned to glass.
That meant monsters.
For the thirteenth floor, that meant tortoise-like monsters that slowly crept up on them by camouflaging into the sandy dunes before suddenly extending their necks up to several strides and trying to snap pieces of Zach and the others. Their heads shot forward with surprising speed and power, but it wasn't enough to overwhelm Zach's barriers.
Stunned by hitting something they couldn't see, the tortoises left their vulnerable necks exposed to the blades of their would-be prey.
