The leader of the Immortal Sect and the Demon Supreme fought a decisive battle on the top of the Tianshan Mountains, and both fell in the end.
When the two woke up, they found that they had exchanged bodies with their mortal enemy, and were bound by a spell to live and die together.
As a result, Tao Zun was forced to strategize in the Demon Sect and teach a group of killers to recite the Tao Te Ching.
The Demon Lord was pinned down at the head of the Immortal Alliance, smirking at a group of old men, and reviewing a mountain of proposals.
Purpose: Break the black-and-white perception through a complete exchange of identity and position. Let the characters truly "travel the path that the other party has walked", understand the helplessness and logic behind the other party's choices, and realize the sublimation from confrontation to understanding.
