She had the ability to distort the truth, and she knew what Old Master Li hated the most. First, she chose to talk about Ye Jian's background. Ye Jian came from a mountain village. She used some unknown method to force her cousin, Ye Ying, out of the university entrance examination and got into the military school herself. These two things already violated Old Master Li's taboo.
He hated it when a person was scheming. A woman should be docile. Even if she had some small schemes, she couldn't let others see through them.
It was a good thing to be scheming. However, if she schemed until others saw her as a joke, she would be stupid!
Then, he heard Du Jiayi say that Ye Jian used her beauty to cast her net widely. She had an ambiguous relationship with many unmarried young masters from wealthy families in the capital city. This violated another one of Old Master Li's taboo.
