I recommend you a novel called "Armory." This novel is about a male protagonist who has a storage space and can summon all kinds of weapons at any time. He grows up in the background of an interracial relationship. In the war between humans and aliens in the novel, the male protagonist constantly broke through his limits through the weapons in the arsenal. As the battle progressed, the shape of the weapons gradually became more humane. I hope you like this fairy's recommendation. Muah ~😗
