Lu Chen, a hunter from Maplefall Village, has practiced the Foundation-Hardening Stance since childhood. Living by his hunting knife and light bow, he protects his frail younger sister and fights tainted creatures and tainted spirits on the outskirts of Ruins Mountain, asking only for a peaceful life.
After one fierce battle, the Monster-Hunting and World-Subduing System suddenly activates. Slay demons to earn hunting points, which can be used to develop his knife skills, archery, Mountain-Sinking Steps, and body-tempering methods. He will temper his mortal bones and advance step by step through the nine realms of body refinement.
But the tainted spirits in the mountains are not naturally occurring. Traces of someone deliberately spreading taint paste come to light. The evil Taint-Calling Sect is secretly behind it, raising monsters and creating monster tides in hopes of awakening an ancient demon.
From Maplefall Village to Yunxi County, from Qingwu Commandery to the heart of Great Chu, and then across four great empires, monster hunters, the Demon-Slaying Bureau, sects and noble clans, and remnants of the evil sects become entangled in layer upon layer of conflict.
No immortal arts, no spiritual roots. He has only the hard-earned strength of his mortal body: his hunting knife slays the tainted, and his Mountain-Sinking stance subdues the peaks.
This is the record of a hunter who uses his mortal body to exterminate monster chieftains, overthrow an evil sect, and destroy an ancient demon.
