Le Tong had some reservations about Chen Jing, but hearing her apologize and express such a sense of enlightenment, Le Tong started to understand. Chen Jing must have had a conflict after returning with Zhu Zhizhou, otherwise, she wouldn't have had such a rapid change of heart.
What Le Tong didn't know was that Chen Jing had already had a major conflict with the Zhu Family because of her eldest daughter, Zhu Qianying's, marriage. After that, she completely gave up on the Zhu family.
Since she had given up, she could now look back on those things that she had previously pretended not to see or deliberately ignored. With the reality in front of her, she had to accept it.
