The undercurrent of the Ming Dynasty is treacherous. The ancient divine object "Luminous Cup" collapsed, and its fragments scattered in the world, turning into "spiritual hub fragments" containing unpredictable power. They can fulfill wishes, distort life, and cause monsters. Since then, under the curtain of the prosperous age, strange diseases, strange objects, and bizarre tragedies have quietly occurred.
At the bottom of Jinling City, Chen Ni, a no-nonsense little man, swallowed the core fragment in order to survive, and was forced to live in symbiosis with the cold and mysterious Cup Spirit "Youying". Since then, he has become the "key" and "prey" coveted by all parties. In order to protect himself and the remaining friendship in his heart, he had to join hands with the gentle and sinister pawnbroker Shao Dong Shen Yan and the reckless and hot-blooded six-door female catcher Lu Xiaodao to trace the series of strange cases caused by the fragments in the smoky streets and treacherous supernatural fog. He faced off against the powerful and scheming commander Leng Qianqiu of the Jin Yiwei, and gradually uncovered a shocking conspiracy about the destiny of the dynasty and the origin of all things.
