Big brother 'drunkenly' fix things

I'm a time travel hoe, I'm a sucker for it so obviously this one is yet again another travelling through time story, however this one follows lan xichen from 5 years post canon going back to the past when leaders of different sects gathered to discuss WWX 's attack on qiongqi path killing multiple jin cultivators , freeing the remaining wen then going and residing in the burial mounds.
And because lan xichen cannot take a rest, because Lans are weak to alcohol he goes back drunk and blabbers in front of everyone:

"wangji, where's my nephew? did you and wuxian fight that he took A-Yuan and stormed to the burial mounds again? brother, you can't do this."
