On the pillar of heavens mountains, all the cultivators except Zhou Yaning and the others had been drugged by Qingfeng Wuying. Zhou Yaning had originally planned to wait until the defense array was set up before sending his men to attack the cultivators and kill Zhao Hai at the same time. This way, they could put all the blame on Zhao Hai, and then they could command the hundred victory Jie.
Even if they couldn't command the hundred victories realm, they could still kill Zhao Hai. This would be equivalent to removing an enemy for the war god Realm. With the support of the war god Realm, the Zhou family could dominate the hundred victories realm.
It was because of this that he had placed all his attention on Zhao Hai. There was no other way, because Zhao Hai had been standing there the whole time, unlike the others who had fallen to the ground.
