Kuafu was shocked to hear that the Red Snake Fire was taken away by Xuanyuan Ba, the daughter of Huangdi. The Red Snake Fire was connected to the sun and the moon in the sky, so the sun lost its light. In the process of recovering the Red Snake Fire, Kuafu fell in love with Xuanyuan Ba. In the end, in order to ensure that the clans in the world could regain the sun, Kuafu let Xuanyuan Ba go and transformed into a new sun, leaving behind the legend of "Kuafu chasing the sun".
