(after resurrection) When Wei Wuxian was experimenting on talismans,he begged Lan Wangji to help him test it.Of course, Lan Wangji agreed reluctantly.They went to a forest so that it's better than causing trouble inside of Cloud Recesses.They also took Lan Sizhui,Lan Jingyi and Jin Ling with them, because they wanted to see it.Well,mostly Jingyi wanted.Anyway,while the trio stood at the side,Wei Wuxian attached the talisman on Lan Wangji and they waited for a result. (You're Wei Wuxian.)
