In the midst of the battle, a group of insects breaks through the defenses of the lingxiao martial house. The insects disperse, and the king's weapon has appeared. The cloud dynasty will be destroyed if the king cannot use the weapon, but if he can use it, the cloud kingdom will survive. The old emperor, who has served the cloud dynasty for many years, is shocked by the appearance of the new king weapon. He calls for the new emperor to come out of his hiding place and face him in a duel.
