It's been a while since the battle, and Caixianyu finally feels like he's done. He can feel his remnant disappearing, but the last blow has seriously injured Caixin, who's fleeing to find a safe place to heal. He's not going to be able to kill Caixin anytime soon, so he'll have to protect Caixin for now. The fairy's-darling can heal Caixin's injury, but it's still not enough to save him. He tells Caixin to kill the old man and let his remnant spirit die in powerlessness.
