There's a kind of deterrence called killing the chicken to warn the monkeys (idiom for punishing someone as an example to others to not do the same thing), and Xu Cheng just needed to first take care of the ones that were jumping around the most.
He got a room at a ghetto motel, and on the wall were posted photos of five people that were going to be the targets of this operation. These five were all rich young masters that had been eyeing his wife, and they also saw Xu Cheng as a thorn in their eyes. If possible, they wouldn't hesitate to kill Xu Cheng and take Lin Chuxue for themselves, and the list included Prince Will.
Xu Cheng tore off Prince Will's photo and sneered, "Don't think that just because you are royalty, I don't dare to do anything. We will wait and see tonight."
