PREDATOR [Grimdark cultivation Monster progression-Weak to OP MC]

He's just a rat in a world of immortals. But Harry possesses a dark secret: he can plunder the traits of any creature, any cultivator, growing stronger by stealing their essence. Yet, his true burden lies in the echoes of a thousand lives he's never lived – dreams filled with impossible horrors that flay his sanity like a raw nerve. The power to steal comes tethered to this madness. And as Harry ascends, the nightmares aren't content to remain in his head. They are seeping out, a slow, insidious change polluting the very fabric of the immortal world. The path to power is twisted, but for Harry, it's a descent into a shared reality where his worst dreams become the world's.
