"No, this is not right," Mei Shu said with a determined attitude. "The recording is enough to prove that Old Wang couldn't withstand Wang Yue's intimidation and promised to help her deal with my mother. She couldn't have done nothing, especially since she happened to take a day off on the day my mother checked into the manor. The world can't have such a coincidence; they must have planned it carefully!"
"But even though we say that, these are just our speculations, without direct evidence. After so many years, it's difficult to make Old Wang and Wang Yue admit their guilt."

Mei Shu knew this well.
After a long silence, she said, "How much of the manor's surveillance footage from back then is still preserved?"
