Yin Dazhao thought that he had stabbed someone to death and was worried that he would be sentenced to death. He knew that confessing was lenient and resisting was severe, so he took the initiative to confess everything in the hope that his sentence would be reduced. Even a suspended death sentence was better than a death sentence.
He had kidnapped Su Hanyan with no intention of hurting her. He only wanted to scare her, then call Li Baojun and inform him to come and rescue Su Hanyan. If necessary, they had even arranged a painful scene to make Li Baojun leave a mark in Su Hanyan's heart.
Li Baojun was injured in order to save Su Hanyan, so Su Hanyan would definitely be grateful. If that matter was brought up again, it would definitely be settled smoothly.
At that time, Yin Dazhao would get a share of the hard-earned money, and Li Baojun would get the connection he wanted. It was the best of both worlds, so why not?
