Reborn, the Imperial Princess Becomes a Dark Arts Celestial Master

[Super sweet romance + resurrection token + amnesia trope + pocket dimension + heroine who closed her heart after heartbreak vs. frail, insecure, love-starved, obsessive male lead]

On her wedding day, Princess Jiang Ying of the Haishu Kingdom is betrayed by her husband. He massacres the imperial palace, and she is hunted down until her body is finally sunk into a freezing lake…

Unable to let go of her hatred, she is sent to another world by a divine artifact and becomes a ghost who has lived for ten thousand years. She could have been a carefree Ghost King in that world, but her obsession with the vengeance she died wanting is too strong. With no other choice, she abandons her cultivation and returns, reborn!

After returning, she decisively heads to the Xingyang Kingdom to seek refuge with its frail, sickly, pure-hearted Third Prince.

On their wedding night, Yan Lixi: She's dead, so let her be dead. No need to worry about her!

On the second day of their marriage, during the tea ceremony, Yan Lixi: Don't worry. I'm here, so you don't have to be nervous.

On the third day of their marriage, Yan Lixi: Until I grow tired of her, no one is allowed to touch her!

…

On day N of their marriage, Yan Lixi: Another day I can't live without A Ying~
