Shen Qingyue, the daughter of a businessman, was in a state of decline. In order to find her missing younger brother and find out the truth behind her family's confiscation, she sold herself into slavery and entered the infamous Seventh Prince's Mansion. She originally wanted to rely on her skills as a housekeeper to settle accounts and find a place in the back house to survive in a low profile.
Unexpectedly, Xiao Jue, the seemingly weak seventh prince, turned out to be the reborn villain who destroyed the world in his previous life. He returned with the memories of his past life, tired of plotting and killing, and just wanted to protect her, the only one who gave him a hand warmer in his previous life.
Xiao Jue saw through Shen Qingyue's talent, promoted her to the position of female official in charge, and handed over all the officials in the mansion to her. On the surface, he is weak and harmless, but secretly he removes all obstacles for her and protects her under his wings.
Shen Qingyue used the account book as a blade and the abacus as a knife to fight evil servants, punish adulterous concubines, and rectify the property in the deep palace compound. She managed the chaotic palace in order and her wealth increased day by day. Xiao Jue, on the other hand, used her as bait and took down the enemies from his previous life one by one. From being allies who used each other, the two gradually became each other's only salvation and reliance. When the truth about the Shen family's injustice was intertwined with the whirlpool of the imperial power struggle, they joined forces to set off a huge wave, eventually overturning the court and joining hands to stand on the top of power.
