The young man is not afraid of power, and braves dangerous shoals and water forts alone. With his chivalry, he wins the support of the people along the river and upright martial arts people. He gradually gathers strength to eradicate evil strongholds one by one, defeating the evil forces that have been entrenched in the river for many years. Finally, peace is restored along the river, and the young man composes a tragic song for the river with his heroic spirit.
