Minglan had always doubted that her mother's death was not a simple accident, but she had no proof when she was little. After she grew up, she secretly looked for the old midwife and checked old medical records, and finally found out that Lin Xiaoniang was the one who had harmed her mother on purpose.

Minglan did not lose her temper or act on impulse. She knew her father cared most about the family's reputation, and simply telling the truth would not bring real justice. She found out Lin Xiaoniang's biggest weakness: her deep wish for Molan to marry into a rich and powerful family.

Minglan did not plan bad things herself. She only let out a few signs that the Liang family might want to marry her. This made Molan and Lin Xiaoniang feel anxious and jealous. Driven by their own greed, Lin Xiaoniang taught Molan to make a huge mistake to force the Liang family to agree to the marriage.

Minglan then guided her father to find Molan's shameful act in person. Lin Xiaoniang lost her mind and admitted all her plans in public, which completely angered Sheng Hong. She lost all her favor and was sent away. In the end, Minglan told her the truth face to face, and got quiet justice for her mother in her own way.
