She was once the legitimate daughter of a grand general's household, risen from the dead. Now she is Shen Yuan, a Netherworld walker bearing the True Sun-Pursuit Warrant. With the remnant soul of a spirit fox by her side, she travels between the dazzling, bizarre world of the living and the unfathomable realm of ghosts, specializing in unsolved cases that straddle life and death and keeping order between the two worlds.
From the blood-weeping official kiln known as the “Ghost-Crying Kiln,” to “The Painted-Skin Bride,” who claims lives, and then “The Inn Between,” which devours living souls... Each strange case reflects the tangled warmth and coldness of human nature, and the endless cycle of cause and effect. Shen Yuan uses the Netherworld's merit as her lamp and her own baleful aura as her blade, cutting through the fog and settling old scores.
Yet as she journeys through one case after another and delves deeper into the mist, she discovers that the shadows of ancient evil gods and the remnants of “Shadow Erosion” lurk behind the cases. A vast conspiracy to overturn the Three Realms is quietly coming to light.
Faced with the call of fate and the tides of the Return to the Void, Shen Yuan must choose: will she be content to serve only as an investigator, or will she step forward to become the final bulwark protecting the balance between life and death?
Cause and effect weave fate; lonely courage seeks the heart. Her records recount not only the cases, but also a mighty song that resounds through the Three Realms.
