At that moment, the Coalition Master and the Myth of Oracle were completely frustrated and horrified about this sudden turn of events because they weren't expecting this kind of trap set by an unknown enemy.
Furthermore, from the White Swordsman's explanation, it was clear that the person responsible was none other than the last-standing myth of the Secret Fraternity.
Moreover, it seemed that the trap was designed to trigger right when the Coalition Master tried to take control of the Myth of White Swordsman's mind, which meant that the person knew about what happened to the White Swordsman before, and maybe he was also no longer under the seal of the Coalition Master as well.
In this situation, the obvious choice would've been to abandon Coalition Pagoda and their hideout, especially for the Coalition Master, who didn't want to be discovered or take risks.
