I saw somebody ask about the other girl from the cover. I'm not sure myself, but there was something mentioned about an other genius cultivator who lived thousands of years ago, that Liu Xiaowan suspects to also have hacks. Maybe they make an acquaintance in the future and befriend each other? Or it's that Mu(the other realm kid) kid's relative? Or both.. Or that kid when it grows up/gets out the secret realm. I'm not sure but those are my favourite self-made theories huhuhu.. But it's also possible that it's just some new character that's gonna be the main antagonist, which means they either have to be besties/lovers with the mc or the most hostile enemies with the mc..
