One Piece: Dungeon Merchant

When Ouyang Xiu came to the pirate world and obtained the 'God-level dungeon merchant system', he began to stir up trouble in the pirate world, and the whole world was turned upside down because of his every move.
Brother Doflamingo: "Fufufufufu~! Boss, when will the [Konoha Collapse Plan] dungeon open, I've been preparing for three months!"
Buddha's Warring States: "Navy, come with me, this time the copy of [Three-Year Covenant] must get an SSS grade!"
Red-haired: "Give me a face, this copy of [Havoc in Heaven] will give me the Red-haired Pirates!"
Whitebeard: "Sons, download the copy with Dad!"
"..."
On that day, the people of Pirate World remembered the fear of being dominated by copies!
