A family has two children—a son and a daughter. The elder brother is carefully feeding water to their family horses according to the horses’ color, while his careless sister is trapped by a female demon. To escape, she causes the horses to become disordered, but her elder brother is taken away by the female demon instead. Before being eaten by the female demon, the brother meets a cow, who promises to rescue him. The brother rides away on the cow. The female demon drops the small items as she chases the boy, but they turn into mountains and rivers that block her way. The boy and the cow escape successfully. In the end, the cow offers its body to the boy and brings him both wealth and a beautiful wife.
