Li Wu Bei's ten disciples were simply waiting along the outer periphery for the Three Elders of Silver Blizzard City, the Solitary Eagle, and Shi Changxiao to move into action. As long as these five men started fighting, this ten man team would immediately make a move for the Mystic Core, and would then try to escape with it.
