When Fang Bai made his move against Wuyin Immortal Emperor and the other high-level members of the Wuying Sect, he had already anticipated that once they showed signs of defeat, they would immediately give rise to the intent to flee.
Therefore, when he summoned the two Puppet Corpses, Fang Bai used his mind to control them, locking their killing intent onto Wuyin Immortal Emperor and the other high-level members of the Wuying Sect.
In this way, Wuyin Immortal Emperor and the other Wuying Sect high-levels would only be able to escape from the current battle if they destroyed the two Puppet Corpses; otherwise, they would be entangled to death, with no chance to flee at all.
