Lan Xichen starts a project

Lan Wangji is pleased that his brother and Wei Ying seem to be getting along like a house on fire. Lan Xichen is most grateful for Master Wei's help. Lan Qiren is just happy that for once it seems like Wei Wuxian is keeping out of trouble and is optimistic that Gusu Lan has finally managed to tame the beast. Unfortunately, he should have learned not to count his chickens before they hatched... and he really should have been focusing on taming a very different sort of beast.
