Shen Weiwan, the concubine of the Shangshu Mansion, whose biological mother died young and her aunt's mother was mean, lived like a transparent person in a deep house. Until one day, she unexpectedly awakened the ancestral "Iron Mouth Breaking" hexagram technique, which allowed her to see the secrets of heaven and predict good and bad luck. However, due to the taboo of "revealing the secrets of heaven will lead to backlash", she had to hide her clumsiness carefully and secretly save money to dream of escaping.
Unexpectedly, her eldest sister refused to marry Prince Jing Xiao Che, the "living king of hell" who was rumored to have killed three princesses. Shen Weiwan was drunk in a sedan chair and got married instead. When he woke up, he was already on the way to Prince Jing's Mansion. Everyone is waiting to see when she becomes the fourth body.
Prince Jing, Xiao Che, had power over both the government and the public, and had a sinister temperament. When he took the strange note that was inexplicably handed over from the bride's hand and said "Southeast corner, behind the rockery, see the light of blood", he narrowed his eyes. This timid concubine seems not as simple as she appears.
Later, she accurately calculated every assassination, resolved every frame-up, and lit up a beacon of light on his way to seize the throne to seek good luck and avoid misfortune. He thought everything was under control, but on the day he ascended to the throne of regent, she left the He Li Shu and a copper coin and disappeared without a trace.
Later, there was a prosperous "Weiwan Gua Shop" in the south of the Yangtze River, and the prince, who had all the power in the world, was squatting humbly opposite the shop, learning to set up a stall and tell fortunes, just asking the Qiao Gua master to look back at him.
