In the era of interstellar collapse, the old cosmic civilization collapsed, leaving behind countless broken star fields, abandoned battlefields, and ruins of ancient civilizations. People in the world regard "star cards" as the basis for their spiritual practice. Star cards can record mechas, bloodlines of alien beasts, star secrets, battle formations and armors, and body and battle techniques. Practitioners call them star card masters, and their combat power depends on: card quality, deck matching, control proficiency, battlefield experience, mental toughness, and mecha suitability. . . . . .
