He just wants to drag Xuu Xiao, Xing Gu, and everyone else down with him. If he has to attack Su Chen alone now, the news would spread, and his reputation, along with Yanxu Palace's reputation, would be utterly damaged.
Especially for Yanxu Palace, which still needs to absorb some super geniuses from time to time to mentor as fresh talents. If their reputation suffers, the consequences would be severe.
However, if the Xuu Family, Xing Family, Qiu Family, Pang Family, and all these First-Order Powers are dragged down together, it would be much better.
"I agree with Young Master Yaun," Elder of the Pang Family spoke up, "Achieving great things requires disregarding minor details. Attacking now, so what? It's such a great opportunity, and once it passes, it won't return."
"I agree too," Qiu Shuang nodded heavily, full of hatred towards Su Chen, thinking that as long as Su Chen dies, what harm is there in an ambush? In fact, she had already had such thoughts.
