Land of Challenge.
The fourth level of the Red Tower.
The plains were vast and boundless, the green grass swaying gently in the breeze. But then...
Boom-
The far-off rumbling sound came one after another, visible shockwaves spreading out like murky water waves, rolling out a white arc. Wherever it passed, the ground was overturned, roots and all. Further afar, tufts of grass flew about, leaving the earth in shambles. The shockwave, reduced only by a great distance, left behind some strong winds that bent the tender grass.
If anyone stood here and looked out, they would find that the closer they were, the more chaotic and dead the earth would be.
Some scattered pieces of grass had already withered and decayed, the soil turned murky black, and the whole earth seemed to have died off.
In the center of this dead earth, there was a mountain standing tall, white with bones.
