Refining a Corpse into an Immortal

In an accident, Feng Sheng became a low-level living corpse - without a heartbeat, unable to see the light, and only had ten days left to live. The only capital is a secret treasure integrated into my body and a broken corpse refining inheritance. The art of corpse refining is supposed to involve living people refining corpses. But I am a corpse myself. So what if I use myself as material for practice? Using corpses as materials and refining as methods "Becoming an immortal" is the goal and also the suspense—— Can a corpse really go that far? Starting from the lowest living corpse, hammer and chisel, you will become an immortal by yourself. This road has never been traveled before. It doesn't matter, I've walked it, it's the road.
