Hmph! I'm afraid the Zhengyuan Sect harbors ill intentions. This matter has probably been noticed by the Alliance sects already. After all, with so many people, news is bound to leak!
He naturally doesn't know, Zhengyuan Sect's plan was to lure everyone into the Confining Array. Even if Drought doesn't act, they would have. Once they return to the Alliance, they would claim everyone was killed by Drought, leaving only Mao Sanfu and a handful of disciples alive, satisfying the sects by handing over the magical treasure. Meanwhile, Drought was subdued by three later-arriving Zhengyuan Sect Elders and brought back to the sect!
