Fanxin and his companions left Grandpa Nick behind and began searching for Fanxin’s parents, who had been missing for eighteen years. They reached an inhabited island and left their boat safely submerged under Little Black’s control as they headed ashore.

Fanxin confronted the giant golden wolf king over being ordered to help, then heard that the Tower of Vicious Wolves held dangerous beasts threatening the surviving wolves. He learned the wolf king wanted him to guard the tower door, but with Fanxin needing to find his parents, Ren Fang suggested he might move the tower into his Wind and Sand Tower.

• Fanxin shielded himself, Ren Fang, and Little Black with wind and sand and demanded that the giant golden wolf treat him as a helper rather than a subordinate.
• The giant golden wolf apologized and explained that the Tower of Vicious Wolves imprisoned vicious wolves, who had killed most of the wolf king’s kin.

• Fanxin ordered Langyue to protect the workers and steel nails in giant air wolves and send them away from the ship.
