But that was only a projection, an illusion, yet at this time, atop the Thousand-faced Soul Tree, an immense force of the soul surged, beginning to transform and create nether soil.
The land where the Thousand-faced Soul Tree took root rapidly turned into a stretch of gloomy blue nether soil, as if merging with the true Netherworld.
In most people's eyes, the Netherworld symbolized death, but in fact, it was neither cruel nor savage, and there was no frequent killing. Aside from the ecology of a few Great Existences, most of it was peaceful and quiet.
Under the nourishment of the nether soil ecology, the Thousand-faced Soul Tree continued to grow, stopping only when it reached 99 meters, having grown to its limit, at which point it branched out into even more root tendrils.
It gained new abilities to summon creatures of the Netherworld and significantly strengthen soul system attacks, which greatly improved the combat power of Mousie's main form.
