I Gain Traits by Slaying Demons, and Mine Can Fuse and Evolve

After transmigrating into a chaotic world of demons and martial arts, I become a junior officer in the Demon-Suppressing Guard. From the start, I'm hiding under a bed, caught between demons on both sides.

Luckily, I can obtain traits by slaying demons. My first is the god-tier trait [Fusion Evolution], which lets me combine different traits and upgrade them into something stronger.

Copper Skin + Iron Bones + Stone Flesh = Indestructible Vajra Body.

Awakened Intelligence + Keen Perception + Comprehension = True Understanding of All Laws.

Great Strength + Giant Strength + Brute Strength + Ten Thousand Jun of Force + Divine Strength = Hold Up the Sun and Moon.

Resilience + Endurance + Recovery = Never Fall in a Hundred Battles.

I spent my whole life slaying demons and vanquishing evil, only for them to say that I'm the real demon!
