When freelance writer Chen Mo received an ancient book anonymously sent to him, he did not realize that he had stepped into a nightmare abyss beyond comprehension. "The Breath of Ereshkigal" - this evil book named after the female ruler of the underworld, is not only bone-chilling, with bloody pages, but also imprinted with the last warning left by his sister who "accidentally" drowned three years ago: "She saw it, so she must disappear."
From then on, Chen Mo's life entered a countdown. On the pages of the book, blood-like handwriting marks the deadline for him to return to zero; when he calls at midnight, a hoarse voice threatens him to hand over secrets he should not have; blood pours from the sink, and black shadows squirm outside the window... He is constantly being watched by invisible eyes, and every step he takes is on the edge of madness.
In order to uncover the truth about his sister's death and to escape this fatal curse, Chen Mo had to turn to friends who studied ancient books and the night watchman of the mysterious bookstore. However, the deeper he explores, the more he realizes that this book is far from the end - it is a living curse, a crack leading to an unspeakable place, behind which involves a cold organization hidden in modern society, and an ancient taboo about the "Page of the Origin" and the seven gates of Hades.
When the blood moon soared in the sky, illuminating the path of memory under the stagnant waters of Hades; when the energy of the shelter room was about to be exhausted, the hunter's giant sword roared outside the door... Chen Mo could only hold the metal page that revealed the truth, took his real name as Ji, and used memory as a boat to go deep into the kingdom of the dead and face the ultimate horror sleeping under the abyss.
Can he break the contract before returning to zero?
