Xi Yin is soon after that captured by the man who seeks treasure on the Penglai Xian Island. Xi Yin looses her tail and gets feet. Even though the men are all amazed, they still want to kill her, but Yang Lie steps in and protects her. He also wraps her in his cloak to protect her modesty.

They are then attacked by the deadly crabs, and run to the forest where the crabs won't follow. Xi Yin is carried by Yang Lie, as she has not yet learned how to walk.
