Me and My Secret Identities, but Make It Narcissism

[Reopening an old story to fill in the missing chapters] Confident, radiant true self VS sharp-tongued, dog-like secret identity After Shiyue died, she was reincarnated and got a second chance at life, along with a golden finger that gave her a secret identity. But she faced a threat to her life as soon as she was reincarnated, and her golden finger was only a defective version. The good news: activating her secret identity could save her true self. The bad news: the secret identity had randomly appeared in another world Shiyue: I'm doomed!!! Taiyin Changming, son of the leader of the ancient Taiyin Clan, has been forced since birth to figure out how to break through the world and return to his true self's side to save her. But still... we're separated by an entire world, true self!!!!!! After a breakdown, Changming suddenly discovers that if he can earn enough emotion points to activate the System's shop, his true self can buy items in another world to protect herself. Taiyin Changming: Thank goodness, my true self can finally survive! In the modern world, spiritual qi revival has begun, and the age of cultivation for all has arrived. Shiyue originally thought she'd be one of those people who risked life and limb in secret realms for resources. But during one trip into a secret realm, she discovers she seems to have an extraordinary identity A Divine Transformation demon cultivator gazes at her with teary eyes and calls her young mistress. A mysterious big shot, looking conflicted, asks her to become his goddaughter. A divine phoenix recognizes only her as its master... Shiyue: I must have gotten up too early. Secret identity, any thoughts on this? Taiyin Changming: Whether it's true or not, first take the candy coating and spit out the bullet, true self. We'll talk when we meet. 1. A trial run at selfcest, just practicing. 2. Yes, it really is selfcest. The female lead and male lead are the same person, but in different bodies, with no blood relation. They end up together.
