Xu Ci and his grandfather have lived in seclusion deep in the forest since he was a child, keeping to themselves and avoiding worldly affairs. Though still young, he has trained in spiritual power under his grandfather and already has remarkably refined inner strength. His grandfather is an old prankster, and they spend their days among the forest's birds and beasts. From time to time, the old man's friends from various schools come to stay for a few days, and Xu Ci has consequently picked up a little about each school's strengths. The days slip by quietly, until, as the boy grows older, one secret after another is revealed during his cultivation. Where exactly is his grandfather? And where will his path to adulthood ultimately lead?
