In the fairy tale, the last weapon Zhang Xiaofan used was a longsword called the " Blue Sky Sword." It was said that this sword was forged by the abbot of the Tianyin Temple. The sword was engraved with mysterious runes and incantations that possessed extraordinary power. In the final battle between Zhang Xiaofan and the Evil Sword Immortal, he used the Blue Sky Sword to defeat the Evil Sword Immortal and protect the peace and justice of the world. Although the Azure Heaven Sword was a magical weapon, Zhang Xiaofan had demonstrated his profound cultivation and indomitable spirit when he used it. This sword eventually became one of his symbols.
