Wu SuYi felt as though she had made a big move on an invisible chessboard. True, everyone to her was a pawn but those were the pawns that Senior Mr Wu made by his cruelty. Almost everyone immediately agree to help her make a witness statement upon knowing that she was going to expose his crimes. Some weren't as complacent in helping as they fear their life would be next to be killed, but others who had lost almost everything just like Ou YuMen and Feng Chuan immediately agreed to help her with the evidence.
One person who she was most grateful of other than those men were none other than her father Jang WenRou. Perhaps due to the anger and hatred he accumulated over the years, he have almost all evidence that could flip Senior Mr Wu's world upside down, providing even with the most detail to add that could worsen the accusation.
