I Opened an Underground Clinic in the Cultivation World and Became Invincible

Shen Yan transmigrates into the Cultivation world as one of its lowest-ranking “corpse collectors” and binds himself to the Black Clinic System. Collect corpses → extract traits, including cultivation, bloodlines, techniques, and golden finger fragments. “Sew” the traits together into brand-new techniques and sell them to the living at a high price. For every stitched-together technique he sells, he permanently gains one year of life and 1% combat strength. Soon, the big shots of the entire Cultivation world are lining up to deliver corpses, all hoping to buy a cheat. The protagonist just wants to hide in his coffin shop and live forever, but as he keeps lying low... he becomes the “Immortal Supreme,” revered by all races.
