In the seventeenth year of the Republic of China, heavy fog closed the city in Shanghai.
There were eight murders in the concession that had no secret room.
All the deceased died peacefully and suddenly, with no injuries, no poisons, and no traces. Only a cinnabar paper figure must be lying on the pillow, with the word "Replacement" lying on the coffin.
The law is ineffective, criminal investigation is impossible, and there are rumors in the market that ghosts and gods are seeking death.
Lu Shiyan, the chief inspector of the concession who returned from studying abroad, is in charge of criminal cases in Shanghai. He believes that there must be traces of crime and flaws in every human heart. He possesses a lost and subtle vein, capable of sniffing out evil spirits, discerning tricks, and unblocking yin and stagnant obsessions, but he has never been able to figure out this strange conspiracy that transcends worldly rules.
In desperate situation, he sought out Yangu Zhai in Yunxiang and met Shen Yanci, a descendant of the mysterious Qi Sect.
This person holds Qingwei Zhenmai, has access to the Eight Gates, the Dawn Formation Technique, and the Cutting of Yin and Yang. He can see through all the disguises of magic techniques in the world with one pair of eyes.
But Zhenmai is destined to lock his body - he only defends but does not attack, and his body will be devoured if he uses the technique.
One is the ultimate in criminal investigation, and the other is the ultimate in mystical skills.
One person can break people's schemes, and the other can break the dead ends of strange families.
Eight pieces of paper substitute for life, the stage locks the soul, the ancient well arrests the evil spirit, the deserted village lends one's life...
One after another, strange and anecdotes that have been lost among the people have come to light one after another. The monsters and monsters that the world sees are never the result of destiny, but rather the sophisticated human-made Xuanmen killings that span twenty years.
At the end of the Qing Dynasty, the old ministers set up a century-old evil formation, taking advantage of the troubled times to refine the yin and use human lives to pave the way, in an attempt to unify the two veins and reverse the yin and yang destiny.
The two ancient bloodlines, which are mutually reinforcing and balancing each other, are fatal enemies and the only salvation in the world.
In troubled times, thick fog covers the game, and chess players in the dark make endless moves.
The human heart is a chess piece, the yin and yang are the board, and the strange gates are the blades.
From then on, one policeman and one mysterious person came together.
