Pig is good at fighting under water, but he is outnumbered by the enemy. In addition, Monkey is not able to give full play to his abilities under water. The dragon king and the princess are both killed, but they cannot subdue the nine-headed bird monster. The Illustrious Sage Erlang happens to pass by and assists in the fighting. The nine-headed bird monster is seriously injured, and flees to the Northern Sea where he barely manages to survive. The ancient dragon’s widow presents the treasure to atone for her crime, so the precious pearl shines anew on the pagoda of Jisan, and the monks of Golden Light Monastery get their freedom back.
