When Ling Cheng opened his eyes, he actually came to hell?
A hell messenger who calls himself "Horse Face" tells him that he has done many evil things during his lifetime, and in order to atone for his sins, he must follow him back to the world to save others.
They have not yet reached the end of their lifespan, but have no desire to live - this is the kind of person they want to save.
But during this long period of atonement, Ling Cheng discovered that this unsmiling and inarticulate messenger from hell seemed to have many things that he was hiding from himself...
Intention: Every day you live is your own salvation.
