In a city shrouded in gray fog, Lin Mo, a mortuary body restorer, unexpectedly awakens the “Eye of Flaws”: by touching a corpse, he can read the rules governing its death. When the funeral home suddenly becomes a “rules-contaminated zone,” where anyone who breaks the rules dies, he is forced to use blood as ink and rewrite the terms of death to save himself. But each time he changes a rule, his body grows a little more transparent. Then he discovers that every rule is written in the same handwriting as his missing younger sister’s... “If saving someone means destroying yourself, would you still change the rule?”
