Under the Heavenly Court, there is a Disaster Management Department, which specializes in dealing with the obsessions of cause and effect in the three realms. It uses the mirror of past events to reflect on other people's thoughts, experiences disasters with one's own body, and overcomes disasters with the Tao.
A group of misfortune messengers with different paths and personalities, while resolving thousands of regrets in the world, face their own inner demons and old calamities. Crossing others also crosses oneself, tracing back to the past, only to realize that the deepest obsession is always with you.
Purpose: To save others is also to save oneself. All obsessions are for cultivation.
