Tianlinggen Zhao Tianxie traveled to the world of immortality and awakened the mysterious system. After three years of hard work, the cultivation value obtained every day will be reduced by the points of his lifespan! He also fell from a genius to a waste that everyone despises. Until an accidental opportunity, I discovered that gathering the corpse of an immortal cultivator can offset the deduction of cultivation! Since then, there has been a demon in the world of immortality who kills people without blinking an eye and collects corpses crazily.
