On the brink of despair, Chen Mo takes a bizarre delivery on a rainy night that will change his fate:
Rules: Walk only through shadowed puddles; light is a lantern that lures souls. Any voice calling your name along the way is bait for the unjustly dead. Answer, and you will be marked. Do not open the package. Look inside, and your eyes will become vessels. Deliver it and leave at once. Don't stop, don't look back. Something is waiting behind you!
As he flees for his life, filthy water flows backward and congeals into a wailing human face. The sticky sound of something dragging itself follows him like a shadow. Then he even hears his childhood friend Lin Xi calling for help from the abyss! Against all odds, he survives, only to find that the delivery has become Lin Xi's bloodstained medical record from an abandoned hospital. Its warning is chilling: "Unusual constitution. A natural vessel! Stay away from yin-tainted things, or your body will be destroyed and your consciousness imprisoned forever!" Worse still, frail and sickly Lin Xi asks weakly, "Chen Mo, were you... in my dream just now?" What she saw was exactly what happened as he fought for his life in the morgue!
When a delivery brings something inhuman, when the price of following the rules is the soul of someone dear, and when sticky, filthy blood seeps from a medical record... Chen Mo's only chance of survival lies in a clue whispered by the deceased stationmaster: "Go find the blind Taoist at Qingyang Temple... Xuan Qing..."
When rules mean life or death, can he decipher the uncanny and protect Lin Xi, all while paying a bill straight from hell? Where will the next delivery take him?
