The Embroidery Office upholds wise rulers and clear government, eliminates treacherous ministers in times of chaos, and slays demons and ghosts in the mortal world. The Han Empire’s oldest and most secretive institution, it dispatches its embroidered-clad agents, armed with axes and imperial authority, to hunt down wrongdoers in the name of Heaven. They punish those who disrupt the world, and subdue demons and ghosts that prey on humanity, upholding the law of the mortal realm to keep the land at peace.
During the reign of Emperor He of the Eastern Han, a series of extraordinarily strange unsolved cases arises: traveling merchants and travelers vanish; ghosts appear and disappear on the outskirts of the city; wooden puppets kill people in the marketplace; and entire families are slaughtered one after another. The cases seem unrelated, yet countless threads link them together. With the local authorities powerless, they turn to the Embroidery Office for help. After dogged investigations, the agents uncover a white horse that speaks, a man who transforms into a bird with a flap of his wings, and ghosts that manipulate dead crickets… These monsters, hidden among ordinary people, have suddenly begun wreaking havoc. Who is behind their rampage? And how will the true identity of the mysterious chief of the Embroidery Office stir up turmoil and shake the foundations of the Han dynasty?
