Wei Xiao went to get Xiao Ling back from Enyo. He doesn't want his nephew to go bothering people who were injured and might worsen the wound if he stays.
Xiao Ling was sleeping by Enyo's side, while Enyo was wide awake and watching the child. The fondness in his eyes cannot be hidden. Enyo was cold to others, but his eyes showed pure tenderness when looking at the child who's heart was pure, yet to be tainted.
"Do you know Bai Daiyu?" Enyo asked. He remembered that a woman claiming that she was related to Bai Chenle was in the scene before he was attacked by the Bull-Horned demon. If Wei Xiao knew that woman, then it is possible that she's innocent or Bai Chenle, Wei Xiao and co. is not.
