In the Dayan Dynasty, an era that seemed to be peaceful and prosperous, strange things were quietly reviving. The strange stories circulating in the market, missing people, and tragedies that cannot be explained by common sense all point to areas that are beyond the reach of mortals. For this reason, the imperial court secretly established the "Department of Immortal Enforcement" to deal with such strange incidents.
Shangguan understood the truth and said nothing. A soul that traveled from the present world became an inconspicuous clerk in the Jixian Division. He just wants to work hard to survive in this strange world, earn some salary, and live a stable life. However, the knowledge about "weird rules" and "thriller games" in his mind made him the most unique "problem solver" in this strange world.
While others were still using peach wood swords and black dog blood to fight against evil spirits, Shangguan Zhili began to analyze the "rules of the game" without saying a word; while others were trapped in an infinite loop of ghosts beating walls, he was looking for hidden conditions that triggered "bugs".
Every mission is a life-threatening adventure; every case solved is the ultimate test of mind and courage. As the investigation deepened, he discovered that behind these strange resurgences, there seemed to be an invisible hand that was weaving a huge conspiracy covering the entire dynasty. And he, this little official who just wanted to survive, had unknowingly stood at the center of this shocking chess game.
