In a city shrouded in gray fog, Lin Mo, a corpse restorer at a funeral parlor, unexpectedly awakens the "eye of loophole" - he can read the rules of death by touching a corpse. When the funeral parlor mutated into a "rule-contaminated area" and those who violated the rules would die, he was forced to use blood as ink and tamper with the terms of death to save himself. However, every time he changed the rules, his body became more transparent, and he even discovered that all the rules were the same as the handwriting of his missing sister... "If you save others, you will eventually destroy yourself. Will you change this rule?"
