He doesn't have a superiority complex, that's a different villain.

When Jing Si was Jing Chen, he gained self awareness and plotted to escape his world because it was so poorly written and full of illogical npcs. Although he was villainous in that world he did so with purpose. He's pretty tame tbh, doesn't treat Luxia badly, and doesn't harm people randomly without a cause. And Luxia does not dislike him either, even if she has no feelings for him.
isn't jing si the goddamn cultivation weirdo w a superiority complex? hope he gets fucked over
