I Forge Eternal Life from Demons!

More than twelve hundred years into the Great Qin Celestial Dynasty, local immortal sects hold sway while demons run rampant through the mortal world. When Fang Yuan wakes up, he finds himself a disciple of an immortal sect in Great Qin. He possesses a Demon-Slaying Heavenly Stele. Slaying demons grants divine essence to improve his techniques and supernatural abilities, and once he accumulates enough, he earns a reward. The Human Emperor Banner, the Immortal-Slaying Sword, the Flying Dagger that Slays Immortals, the Eastern Emperor Bell, the Heavenly Stems and Earthly Branches... Across the nine heavens and ten lands, amid the mortal world, the road to immortality stretches on. I shall become the revered leader of the sect!
