Actually, Yan Ze had locked onto one final target for what happened back then, and that was Shoufu Zhao.
Zhao Mei'e was a woman who lived in a house all year round. Even if she had some tricks up her sleeve, she couldn't have done things so flawlessly.
There must be someone working from the inside out to do things so cleanly and clearly.
However, there was no evidence!
All his guesses were just his guesses. No one knew what had happened back then, and no traces could be found.
By the time his grandfather reacted, it was already too late. Even if there were any clues, they had long been erased.
It was also because of this that his grandfather did not take any action back then.
Yan Ze could understand his grandfather's thoughts. Even if his father was disappointing, there was still a trace of father-son relationship in his grandfather's heart. He couldn't completely abandon him.
