She'll probably wake up in her own body. In the first two worlds, both women died, but in this one, Su Luxia got there before the holy water killed her. Not only that, but she still has her family artifact, and she said that if she stored a portion of her powers in it, then even if they're met with misfortune, they'll still be able to wake up after thousands of years. The only reason that it wouldn't have worked before is because of Youji and the blood pact, his being alive meant her power would transfer to him, but since the blood pact is gone, she doesn't have to worry about that anymore and the artifact will restore her.
