Immortal for a Hundred Lifetimes: From the Start, a Demoness Steals My Essence

Beneath the veils of misty peaks and immortal mountains, who can unravel the mystery of immortality? Amid the illusions of time and reincarnation, who lies in wait?

I awoke from the mortal world and opened my eyes to this place:

Sword-riding, light-dodging, pill cauldrons, ancient formations, tribulations of lifespan; source-seizing, baleful energy refinement, destiny, the remains of ancient gods, karma spanning a hundred lifetimes.

Immortal light falls upon the mountains, and karma has never faded. This is the story of a visitor from another world.
