S1·E5 Heretic Path

Wei Wuxian sneaks out at night again to enjoy his favourite wine, but is caught by Lan Wangji for the second time. As Wei Wuxian does not want to give up, he fights with him and causes them both to fall outside of the Cloud Recesses, which is a rule broken. This causes them to be punished by being beaten. After hearing of a way to relieve the pain, Wei Wuxian joins Lan Wangji in the Cold Spring. Wei Wuxian uses this as an attempt to make friends with him, but Lan Wangji continues to refuse. Later, they hear a strange sound and rushes to defeat the feral zombies that have escaped. Lan Wangji holds up until Jiang Cheng and another disciple comes to give Lan Wangji his guqin, and successfully defeats the zombies. On the other hand, Wei Wuxian does not have a weapon and faces difficulties at his end. While fighting, he sees a rabbit and protects it while running from the zombies. One of them gets too close and resentful energy starts entering his body. Jiang Cheng comes just in time to return him his sword and they defeat the remaining zombies. Jiang Cheng then gets mad Wei Wuxian attempted to harness the resentful energy, which is forbidden and warrents his execution, but Wei promises not to do so again, having resisted its influence.
