yang Jian durability

Yin Jiao then cast up the Heaven Overturning Stamp to hurt Yang Jian, but that was ineffective too, as Yang Jian had his bajiuxuangong, and could transform himself as the wind goes.

As Yin Jiao galloped northward, the path became narrower, and he had to abandon his horse and run on foot. As the enemy closed in behind him, he prayed to Heaven, "If my father is still to be the ruler of the kingdom, may I knock out a path with my stamp and escape danger. If not, may I die today." He raised his hand and hurled the stamp at the mountain. With a great crash, the mountain split in two, leaving a road wide enough for him to run through.
