In his previous life, Gu Heng spent sixteen years redressing the case for the Duke's government. When he was beaten at the gate of the capital, he suffered from fetal poisoning. When he was dying, he activated the time-returning formation. He just wanted to go back to the age of eighteen and go back to the wrong path.
After his rebirth, the first thing he did was to marry Shen Qingyan, the legitimate daughter of Duke Ding, before the prince.
Shen Qingyan lost his memory when he woke up from a coma, but he could instinctively draw building plans, read account books, and see at a glance whether a ladder would fall. It wasn't until the dream fragments gradually came together that she discovered what was living in her body.
He walked step by step in the court with the truth he found out in his previous life, and she walked into his chess game with her hand-drawn drawings and calm mind. From a strange couple separated by a screen to close friends side by side.
Everything that was too late in the previous life will be available in this life.
