When Jun Xie noticed the assassins approaching in his direction, he came up with an idea to prevent being caught. He feigned collapsing but he was actually concentrating every ounce of his skill on to his chest. The buildup of energy caused his outer and inner robes to protrude outwards, which formed two delicate layers of protection over his chest. When the assassin directed a heavy blow on Jun Xie's chest, the pulsing outer robe acted as a shock absorber and absorbed most of the momentum. Some of the resultant momenta from the kick was also dissipated by the pulsing inner robe.
