During the Yongxi period of the Great Chu Dynasty, the abandoned ancient houses in Jinling City were like silent tombstones, hiding unknown bloody secrets.
Su Wan, the last descendant of the Su family, was once a family founded by the head of Qin Tian Jian, but was expelled from the court due to an old case. The ancestral "Secret Records of Construction" was burned, leaving only the clue of "the fragments hidden in the Blood Coagulation Manor". Holding half a bronze Kanyu Order, she stepped into the gloomy ancient houses, vowing to uncover the truth about the injustice done to her family.
The blood vines of Ningxue Manor are wrapped around the bones, the clocks of Wuchang Courtyard are ringing, the bronze towers of Zangfeng Garden, the witches' incantations of Huihun Pavilion... Every ancient house is a game of life and death. The victims of serial murders have strange coagulation needles inserted in their throats. The house numbers of the crime scenes point to the deeper and deeper darkness.
Pei Zhao, the young minister of Dali Temple, wears a silver mask and hides old scars behind his ears. While he is investigating the murder, he seems to be also looking for answers related to his own life experience. From suspicion to side by side, the two of them dismantled the mysteries of the "Blood Coagulation Array" and "Soul-inducing Technique" in an ancient house densely packed with institutions, but they didn't know that the green bricks under their feet had been soaked in the blood of three generations.
When the witch's notes surfaced, and the royal family's conspiracy intertwined with the curse of Huangquan, they were shocked to realize that behind the door of the ancient mansion, there was not only the truth about the burning of the Su family, the injustice of the Pei family's destruction, but also the secret of "Huangquanwu" that could overturn the dynasty - the sealed evil ghosts slept there, as well as the bloody promise between the late emperor and the witch.
Su Wang breaks the formation with a silver flute, and Pei Zhao protects her with a soft sword. In the illusion of seven emotions and soul refining and the mechanism of yin and yang inversion, they are both puzzle solvers and chess pieces in the game. Every scratch is a warning, every drop of blood is a guide, and what ultimately needs to be broken is never the mechanism of the ancient house, but the obsession deep in the human heart.
From the setting sun of Jinling City to the dim fire of Huangquanwu, every ancient house she walked through told: The so-called fate is just the truth that has not been revealed; the so-called investigation is ultimately the most decisive redemption of the past.
Intention: Only by joining forces can we break the situation
