Yan Xing, an Earthling with the unique ability to traverse between Earth and a magical realm, revolutionizes commerce across all civilizations. Elves covet his imported silk and cutting-edge longbow rockets. Orcs eagerly purchase premium soap alongside his devastating Roarer tanks. Human nobility obsesses over his exquisite porcelain collections while installing magnetic coil technology throughout their mansions. Even the Undead seek his craftsmanship, commissioning luxury coffin sets to enjoy horror series during eternal insomnia. When Angels, dragons, and demons inevitably discover his empire, Yan Xing expands his vision without hesitation. "Every race and creature belongs in my marketplace," he declares, unveiling his most ambitious offering yet: portable Doomsday Judgments for the divine, draconic, and infernal clientele.
