The deeper you go, the darker it gets - and Kaz is about to learn just how dark the depths can be.
Leaving the upper levels behind, Kaz, Li, and their human allies descend into the mountain's brutal mid-levels, where the rules have changed and the monsters are no longer recognizable. Captured by the relentless mosui and surrounded by fulan-twisted horrors, survival demands more than strength - it demands sacrifice. As Kaz pushes his cultivation to its limits and his companions prove their worth in blood and bone, one question haunts them: how far must they go to find answers, and will those revelations be more than they can handle? A slow-burn progression fantasy of treacherous descent, tested loyalty, and the courage to face what lurks in the dark.
