The Lan's are holding a week-long conference in the cloud recesses. Wei Wuxian intended to spend this week "getting along" with his brother who naturally was bound to attend.

Despite them being in the home of the Lans there are multiple reports of thefts happening at the various participating sects. A mystery Wei Ying simply can not resist looking into. But as he does, something truly unexpected happens. Jiang Cheng, with a white headband wrapped around his wrist, announces his engagement in front of the entire cultivation world.
