Before long, Xiao Yao and the others followed Elder Mo to the third floor of the Spirit Medicine Hall. Seeing the layout, so different from that of the second floor, everyone could not help but gasp. Even someone like Xiao Yao, who had witnessed all manner of grand scenes, had a flicker of shock in his eyes.
