I Kill Monsters And Steal Their Body Parts To Evolve [LITRPG AND PROGRESSION FANTASY]

Ryan was a UFC fighter who never won a final. Every loss, every "loser" chant from the crowd, a life spent one step behind everyone else. Then his heart gave out mid-fight, and he woke up as Xaviour, in a world he doesn't recognize, a dire wolf's jaws inches from his leg.

He kills it. And something changes.

The Genesis Blueprint lets him harvest the body of any Grimbeast he defeats, legs, claws, even organs, wearing their power like a second skin. Wolf legs for speed. A dragon's lungs for fire. Enough parts, enough kills, and there's no telling what he could become.

But strength alone won't save him. Every kill draws him deeper into a world that doesn't care how many times he's already died. Xaviour has spent his whole life losing.

This time, he doesn't plan to.

What to Expect:

A reincarnated MC with a genuinely unique power system, no generic "level up and hit harder," Xaviour's growth comes from choosing and combining monster parts.

Named special moves tied to each equipped part.

Fast-paced chapters, action-forward, minimal filler.

Dark fantasy tone: real stakes, real injuries, real consequences, but not grimdark for its own sake.

A MC who's not OP from day one, early chapters are genuinely dangerous for him.

A strong side cast that grows alongside the MC, not just background characters standing still while he levels up.

Mystery-driven, arc-based structure, each arc feels like its own self-contained story while carrying the same core cast forward.

Some comedic banter and lighter moments to break up the tension.

System notifications and stat/level displays, but used sparingly, not info-dumped.

 Update Schedule: 8 chapters on release day, then 2 chapters daily through the rest of the first week. Starting week two, updates settle into 1 chapter a day, posted at 6:00 PM EST.
