Su Qianqian was the most unpopular concubine in the Hou family. Her biological mother died young, and her stepmother worked hard with her. The promised marriage has failed, and the eldest sister is going to marry Gu Changyuan, the rumored general who kills without blinking an eye and is full of evil spirits. The aunt's mother was reluctant to let her own daughter fall into the fire pit, so she knocked Su Qianqian unconscious and stuffed her into a sedan chair, making her a substitute bride.
Everyone was waiting to see her joke, thinking that she was either scared to death on her wedding night or crushed to death by the rules of the General's Mansion. Unexpectedly, after her forehead was broken, the old hairpin left by her mother was stained with blood, which allowed her to see the past things that others had suppressed in their hearts. The evil servant is greedy for money, the mother-in-law keeps the accounts, the noble lady hides her ugliness, the powerful minister buries the case... From now on, there are no secrets in the capital in her eyes.
On their wedding night, Gu Changyuan lifted his hijab with a cold face. Su Qianqian wanted to pretend to be fainted to save her life, but suddenly she saw that when she was a child, she failed to grab the candied haws. She hugged the doorpost and couldn't stop crying. She was silent for a moment: "General... You loved eating candied haws when you were a child?" Gu Changyuan's eyes darkened: "How do you know?" Su Qianqian immediately sat up straight: "I also know that Granny Wang of the warehouse hid the banknotes in the chicken coop last night."
From then on, she purged evil slaves in the General's Mansion, fought against her aunt, tore apart the white lotus, and dismantled conspiracies, and gained a foothold by relying on the dark history of the powerful people in Beijing. But when the old hairpin pointed deep into the palace wall, she realized that her mother's death was not an accident, and her replacement marriage was not a coincidence. And the general that everyone feared had been waiting for her many years ago.
