Yue Pengcheng was taken away. Yue Tingfeng had no part in the rest of the matter.
When he was about to leave, Ding Fu suddenly said, "Mr. Yue, thank you so much. If it weren't for you, I would have had no way to escape from a living hell. I truly am grateful for you!"
Ding Fu was trying to get on Yue Tingfeng's good side through her words, showing how appreciative she was. She wanted to tell Yue Tingfeng that she had completely broken up with Yue Tingfeng. There was absolutely nothing between them anymore. She hoped that Yue Tingfeng would see that she had greatly assisted him in the matter today, so they would not harm each other from now on.
Ding Fu had probably realized that no one could go against the Yue family. Yue Pengcheng was Yue Tingfeng's own father, yet he resides in a cell now.
When Yue Tingfeng wanted to get rid of somebody, he would leave no room for retaliation. Yue Pengcheng did not have a single inch of ground to stand on.
