This is a continent that mainly focuses on weapons. There are some people on this continent who can unlock their contract attributes at the age of eighteen, choose a suitable spiritual weapon based on the attributes, and their fighting methods are all based on spiritual energy given to the weapon.
I don't know when, strange beasts descended from the sky, and they wreaked havoc and cruelty. Those who mastered the contracted spiritual weapons took up weapons to fight against the beasts. The fate of mankind is also entrusted to these people.
