In this instance, the song and Wuxian's plans are a happy coincidence. The person's whose mind is being cleansed in Lan Zhan's room is Yuan's. All the horrors he'd just experience from being attacked were going to haunt him and if there was even the slimmest chance the song could heal any of that damage, he was trying it. It was better than feeling so powerless, knowing his child had suffered his whole life and again moments after Lan Zhan learned who he was. The guilt was almost more than he could bear.

Fortunately by now, Jin Ling was simply too exhausted to need any more help staying asleep. The soft music, the comfortable bed, and Yuan curled against him were plenty to keep him in a deep slumber. The Chief Cultivator was glad for this since he knew as soon as the young man rose, he would need to do the hardest thing he's ever had to do- let go.

At least this time it was into the arms of a loving family and not into a rocky cavern. His hands stop for a moment and he takes a shaky breath to steady him. No matter how long it's been or how often he has a very alive and happy Wuxian in his arms, a piece of him breaks whenever that memory comes back to him.
