In the 18th year of Chengqing's reign, a weeping bird came to grant the marriage decree. Su Ci, the concubine of the Taifu Mansion, was forced to put on a wedding dress and marry Prince Jing on behalf of her eldest sister, who was rumored to not survive the weak crown. The world only knows that this marriage is a murder plot carefully planned by Concubine Lin, but they don't know that hidden under the red hijab is the "Secret Records of Tiangong" that has been lost for hundreds of years - as well as the secrets of the previous dynasty guarded by three generations of the Su family.
On the wedding night, the poison was quenched with wine, and there was a gu-melting soup hidden under the wedding bed. Xiao Jamgyi coughed up blood and put the hairpin against her throat: "Does the princess know that your grandfather planted the same fate Gu in my heart before he died?" Su Ci showed the bleeding star tattoo on his back with his backhand: "Does the prince know that every dark pattern on the waterway map of the imperial mausoleum is a talisman for death?"
In the deep palace, Concubine Lin stroked the crystal and smiled softly. She used "Sun Tzu's Art of War" to train dead soldiers, used "Compendium of Materia Medica" to prepare poison, and even transformed "Xuanji Picture" into a heart-killing weapon. When "Life is just like the first time we met" was sung in Beijing, only Su Ci saw through her hand in tampering with the hexagrams - the scent of osmanthus lingering on the imperial edict was clearly poisonous rouge soaked in corpse oil in the dry well of the cold palace.
On the rainy night when the mechanism Suzaku smashed into the glazed tiles of the Golden Palace, Su Ci finally solved the bloody chess game left by her grandfather. Twelve copper coin hexagrams pointed to the birthmark on her wrist, and the star chart tattoo on Xiao Jamyi's back began to burn - it turned out that the Heart-Eating Gu was not trying to eat people's hearts, but the souls of three thousand artificers who were buried alive in the imperial mausoleum a hundred years ago.
