The trial ground was located within the grand dome building safeguarded by the Radiant Lighthouse.
At first glance, this building only seemed as large as a regular sports stadium, but inside, it contained a world of its own. As powerhouses from various realms tentatively passed through the golden-lit grand entrance, what unfolded before their eyes was an expansive new world.
Mountains hundreds of meters high stood among the vast clouds, each of them specially shaped and maintained, not only at equal distances from each other, but also identical in height, size, shape, and the flora planted upon them.
The mountains weren't rugged, but rather smooth and even; they resembled giant truncated cones, wider at the base than at the top, more than actual mountain peaks.
Unique white buildings stood resolutely on the stepped sides of these mountains, neatly arranged in sequence.
