I Pull a Gatling Gun From the Fridge, and You Call That a Melee Weapon?

[Big Brain System o.O? + Game Dungeons + Invincible]

In a parallel world, every so often, selected people are pulled into dungeon spaces to play games governed by special rules.

The first game: a battle royale with melee weapons.

Everyone can bring weapons into the dungeon and take part in the battle royale, but they can only fight with melee weapons.

Break the rules and you will be instantly erased!

Qi Chen's Big Brain System asks: "Melee weapons?"

"If I take a frozen Gatling gun out of the freezer, does that count as a melee weapon or a firearm o.O?"

That brilliant logic is enough to crash the dungeon's consciousness.

So while everyone else is hacking at each other with swords and knives, Qi Chen's chilled Gatling gun is already spitting blue flames.
