After the apocalypse, the world is overwhelmed by yin energy and the dead roam unchecked. The Twin Gates, a private paranormal investigation agency, steps onto the scene. Cen Jiu, known as “Hell’s Writ,” and Shen Banxia, the “Chatterbox Bodhisattva,” take on one case after another: first a haunted old apartment building, then a desolate village where “living people turn into trees,” and more. Shen Banxia unexpectedly acquires the Golden Needle Art of Ghost Deliverance, which lets her heal the living, guide vengeful spirits onward, and set up formations to fight evil entities. This art helps the Twin Gates stand out in paranormal cases, widening the gap between them and other teams as they work alongside a history-obsessed shut-in, an intern, and other teammates. With this art, they are destined to uncover the secrets behind the resurrection of the dead, save the world, and bring daylight back.
