In the instant that the trap activated, Wang Yu dodged to one side just in time. As the traps were placed in bushes, the others didn't manage to see this, otherwise Little One would have completely given up on fighting Wang Yu.
Things like traps were instantaneously activated skills, so was it still humanely possible for one to dodge in the instant that the trap was activated? This should have been impossible even for bosses right? Of course, bosses wouldn't bother dodging this sort of lousy trap. They would simply crush it with a single step.
So what if Wang Yu had been silenced? Against 10 people, it was just a matter of time before they fell.
By now, the 6 seconds of silence had passed and Wang Yu used [Crushing Blow] to move over 5m in distance. [Thunder God's Stomp] took out another three Magicians, and with a casual wave of his left hand, [Void Seizing Palm] brought Little Seven into Wang Yu's hands where he was squashed to form a burst of white light.
