I’m Just Doing a Little Cultivation, What’s the Big Deal?

Secret Identity Stories Where the Protagonist Never Gets Found Out, Preferably Playing Other People

The Protagonist Plays an Entire Cast Alone and Creates an Organization Made Up Entirely of Themself

Looking for books like "Turning the World Upside Down: Playing a Villainous Big Shot from the Start".

Secret Identity Stories Where Each Clone Has a Separate Individual Identity

I'm looking for books like "Detective Conan: A Fleeting Life, Yet to Be Named".
