Guilty conscience
Because Ji Yao was too young and Ji Wen was passed out, Qilin Luse managed to get the bird out of the kid's hand by coaxing him to take something else.
Seeing the shiny teething necklace made of polished jade gemstones the little Ji Yao dropped that bird so fast like he was afraid the tall giant would change his mind. Qilin Luse left with the bird in hand that is after he splashed Ji Wen with cold water waking him up from his drunken stupor.
When he woke with a start he only saw his son gnawing on something he obviously didn't buy for him and his body drenched in water. At that time he stupidly asked Ji Yao if he had seen who did this but the little dumpling just giggled at his misfortune.
The bird might have been rescued from the cute baby but it was still so pitifully drunk. Qilin Luse was left with no choice but to bring him along and take care of him.
