There is zero consistency in the story. Names, abilities, and numbers often change even in the same chapter they’re introduced. Also, I’m about 95% sure that this isn’t an original novel; the “author” either found some unpopular Chinese novel and is using a shoddy MTL program (which would explain the name/gender inconsistencies and the barely passing familiarity with the concept of numbers) or they’re just a terrible author.
Either way, don’t bother wasting time or coins on this. You can’t get either of those back, after all.
