Fighting in the Galaxy

Because of the population explosion, the Earth government decided to implement an exile plan and exile the prisoners in the prison to a galaxy 55,000 light-years away. The exiled people (Terran humans) did not perish since then. Instead, they developed technology in the distant stars that far exceeded that of the earth, and continued to expand from the exiled galaxy! In this era where laser guns and electromagnetic guns are the main themes of war, a group of illogical war madmen have emerged. They wield primitive swords and guns and wear wild animal skins; but their bodies are as solid as diamonds, and their shouts are as powerful as thunder! —— When the Terran giant aircraft carrier wandering the galaxy encounters the giant dragon that descends from the epic, when the thunder and lightning judgment of the Porotos Light Archon encounters the nebula lightning of the Holy Domain Magician, when the insect plague of the Zerg (zerg) Queen encounters the undead summons of the shaman witch, when the magnificent Mecha King Kong encounters the mountain-like Goron stone man, when the psionic signal receives the declaration of war from the psychic link... War is about to break out! This feared iron-blooded army comes from a certain guy's tribal system and only serves him. And the reason why he started the war was just to collect enough trophies... And then go home!
