Chimera King 3: Rulers of Last World (A Harem LitRPG Adventure)

Cherish your Girls - Hold the Wall - Reforge the Land.
Cade and his band of bodacious companions have forged a foothold in the world of Antinium. Now they must defend it.
A
dungeon, with seven levels of increasing difficulty, waits to be
explored. Invaluable resources, and more importantly, the power to
control the dungeon itself, stands as more than an enticing reward to
lure Cade in. The beasts of Antinium have mutated and turned from a
nuisance into a full-scale threat.
But most concerning of all is the evil that festers in the darkness.
For
the sake of Antinium's people, the Rulers of Last World must prove the
light of their newly forged society is enough to withstand the night...
