Honestly it's pretty shitty that the brother was just going to die when he can completely wipe out that ling family with his strength.
At least, that's my understanding that they're brothers. This 'daddy' and the Xiao family head in the small town.
I understand like it's his job and he probably doesn't get days off. It's just... I'm sure he has a guard or whatever that's new entering spirit realm or 2nd layer. Can't send them to scare ling family?
