The demon baron had tried to approach to the central axis of the hall many times. Being besieged by the three weapons under the control of Zhang Tie, the demon baron didn't break through the central axis until it fell down.

This buffalo would gradually become fatigued, sluggish and finally fall down no matter how mad and fierce it was at the beginning.
