[Evil friends trap each other·Two-way travel·I die and you don't live·Abstract]
Shen Ji transforms into Senior Brother Duanfang of the Immortal Sect, and Xie Qingyun transforms into the Young Master of the Demon Realm - they are sworn enemies on the surface, but in fact they are fellow time travelers who cheat each other. They have cooperated for many years, done many bad things, and blamed each other, but they still refuse to admit that they are friends.
