The next morning, Biyuan tries to rustle up a solution for her mother's moldy rice, but she can't find it in the post-house's warehouse. She tells the doctor that her parents died young, and that her brother was the only one who supported her and her brother. Biyuan tells her that her current salary is enough to feed her family, but that she should ask the doctor to bring the solution to her brother, who is busy preparing detoxification soup for the Lord Protector. The doctor tells Biyuan to leave the soup in the warehouse, but Biyuan says she should continue to investigate the notebook. She asks the doctor if he believes that her mother was imprisoned at the cold palace for having an affair with a lord protector, and the doctor replies that she would never have done such a thing. The notebook that Biyuan has is clearly written by her mother, and she thinks that it is the handwriting of the noble consort. When the lord protector left the capital, she was not allowed to visit her mother.
