On their wedding night, Zhu Mingjin married into the Pei Mansion, but a coffin with her old name written on it was delivered outside the wedding hall. The old case of the lampstand from ten years ago, half of the ash seal, and a page of broken accounts tied her and Dali Temple Shaoqing Pei Wenzhou to the same marriage contract.
One is an orphan from an old case who has hidden his name for ten years, and the other is a cold-faced young man who has been responsible for his father's case. For a period of three months, the two pretended to be husband and wife and secretly investigated old accounts, from the wedding hall in the capital to the granaries of prefectures and counties, and from the depths of the palace walls to the lights of the world.
She originally just wanted to seek innocence for the old case, but later she discovered that if the old system was still there, the next fire would burn more innocent people. So the Ember Platform was restarted, and the lamp never went out. She wanted the erased name to illuminate the world again.
