Sang Zhu is the personal maid of Miss Lu Ningxue of Shangshu Mansion. According to the family's pre-marriage inspection etiquette, she needs to accompany her closely. On behalf of the Miss, she inspects two fiancés - Qin Changqing, a decisive general who kills the country, and Gu Wenjie, a gentle and gentle Jinke Scholar, to choose a son-in-law for the Miss. In her past life, she told the truth and bluntly said that the general was of reliable character. However, because the lady favored weak scholars, she was angered and died tragically. Once he was reborn and returned to the end of the investigation, Sang Zhu was determined to live for himself. She deliberately concealed her inner judgment and persuaded the young lady to choose the number one scholar who seemed to be a good man.
