Why didn't Xiang Qiang believe Ding Hao's reason? The answer is actually quite simple, it's because he understood Ding Hao.
Ding Hao wasn't the type to place heavy importance on money. During the three years he led the Tidal Gang, every single account was clear and verifiable, without any possibility of under-the-table dealings. This, Xiang Qiang could guarantee with his life.
If Ding Hao had said that he didn't want to see the Tidal Gang, which he had built up with great effort, become just another branch under The Inferno Society, and therefore harbored killing intent towards Wang Yu, then that might have been possible. But to say that Ding Hao had made a great deal of money from the Tidal Gang, and that he was unsatisfied with Wang Yu for cutting off his revenue stream, Xiang Qiang would absolutely not believe it.
