I, the Fake Upper-Class Aristocrat

Wang Sui traveled to a parallel world. This world is both similar and different from the world before me. There are only five countries left in the world. People advocate the title system, and Wang Sui is one of the ten great dukes. Wang Sui originally thought this was the limit, but why are there still various abilities? "Holy crap, is this a mythical world or a modern world?" Wang Sui was also a little confused! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
