Chosen as a Sacrifice, I Slaughter My Way Through a Man-Eating Cultivation World by Plundering

This is a twisted world where spiritual energy is severely polluted. The more you cultivate, the sooner you die! The harder you work, the more likely you are to become a miasma! And yet, everyone in this world cultivates immortality. Its rules drive people to cultivate like mad, only to... become those terrifying miasmas! My name is Chang An. My parents sacrificed me, stripped the flesh from my bones! But I... survived!
