After the Yi Divine Bow was crafted, it had to be placed in the Nine Heavens Thunder Prison to undergo the most violent and primal forces of Heaven and Earth for purification. From the start of crafting to the completion of the bow, it took exactly forty-nine years! Only such a crafted Divine Bow was qualified to be called the "Yi Divine Bow".
There is only one Yi Divine Bow in the world. The first demon it shot and killed upon its emergence shocked the world; it was none other than the renowned Three-legged Golden Crow.
