Kim Ha-neul was expecting mandatory military service.

Instead, she wakes up as a cute young girl with an EX-rank Legendary Blacksmith class, and an enhancement skill unlike anything the world has ever seen.

There's just one catch.

Every enhancement has a 99% chance of destroying its target.

Weapons, artifacts, monsters, people... even system abilities, nothing is off-limits. Most attempts end in spectacular explosions, but the impossible 1% success rate creates absurdly powerful results that rewrite the rules of the world.

For everyone else, enhancement is a calculated risk.

For Ha-neul, it's an addiction.

As clips of her outrageous enhancement streams spread across the internet and impossible miracles become reality, hunters, guilds, and viewers can't decide whether she's the world's greatest blacksmith... or its most dangerous lunatic.
