My Fusion System -I can fuse anything

Synopsis — My Fusion System: I Can Fuse Anything In a world ruled by power, levels, and blood-soaked hierarchies, strength is everything—and weakness is a death sentence. After awakening the Fusion System, a mysterious ability that allows him to combine anything with anything else, the protagonist is thrust into a brutal fantasy reality where survival depends on creativity as much as raw force. Steel can merge with flesh. Magic can fuse with instinct. Enemies can become resources. But power without control is just another form of self-destruction. Still struggling to master his volatile abilities, the protagonist travels alongside seasoned elite-tier adventurers, taking on quests no sane warrior would accept. Their current target: a necromancer hidden deep within a northern castle, commanding hundreds of undead—basic, elite, and rumored master-tier abominations capable of wiping out entire parties. Outmatched, underprepared, and walking a week straight toward near-certain death, the group must rely on strategy, trust, and the protagonist’s unstable fusion magic to stand a chance. Every battle forces him closer to his limits. Every fusion risks mutation, loss of control—or something far worse. As the lines blur between weapon and wielder, ally and monster, one truth becomes clear: The Fusion System isn’t just a power. It’s a test. And whether it will forge a legend… or create something the world was never meant to endure remains to be seen.
