City: Wash Iron Man's Suit at the Beginning

Traveling to a parallel world, Wang Xiaosheng inherited the laundry and awakened the system. From then on, everything can be washed! System: "Succeeded in washing Iron Man's suit! Obtained Iron Man's billions of wealth!" Iron Man: "Wow! The suit washed by Wang Xiaosheng actually has zero power! It directly extracts vacuum into energy, which is comparable to a perpetual motion machine!" System: "Succeeded in washing Qin Shihuang's dragon robe! Obtained the blessing of Chinese luck!" Qin Shihuang: "This is it? The dragon robe washed by Wang Xiaosheng can actually extend my life for fifty years! So why worry about establishing a hegemony?" System: "Succeeded in washing Luffy's hat! Obtained the Haki of Knowledge Color, Armed Color, and Overlord Color!" Luffy: "Sugoi! The hat washed by Wang Xiaosheng can actually make me immune to the suppression of Hailou Stone! I am determined to be the Pirate King!" This novel and its characters are purely fictitious.
