The two young heroes are discussing which of the two peaks to attack when their older brother asks them to open the three charms that his master has given him. The master tells them that if they cannot open the charms, his first name will no longer be zhu. The elder sister tells the young heroes that the sign at the inn is the result of a three-year-old incident in which the old shopkeeper's leg was injured by a practitioner of the beggar's religion. The practitioner was Zhang Mazi, an elder of that sect. The young heroes were unable to find an explanation for the old man's death, so they put up the sign in protest.
