In a world transformed by Nautlix, a 25.6 trillion dollar tech powerhouse led by the world's first trillionaire, Patrick Castle, the boundary between human labor and artificial intelligence has been entirely redrawn. While the company's autonomous "Evolve" robots took over lighter consumer and factory roles, it was the "Hercules" series that revolutionized heavy industry. A massive, human-piloted exoskeletal suit supported by semi-autonomous AI, Hercules did not replace blue-collar workers; instead, it amplified their strength, creating an entirely new class of highly paid, skilled professionals without requiring a university degree.

In South Korea, this technology sparked an unprecedented industrial and cultural phenomenon known as the "Korean Hercules boom." As industrial accidents plummeted by fifty percent, specialized academies emerged overnight, offering a lucrative career path that bridged gender divides and provided a lifeline for unemployed youth.

Against this backdrop of rapid societal shift, 24-year-old Seo-Yeong and her colleague sit in their construction company’s cafeteria, watching the news as their employer begins leasing Hercules units from Doosan. Reflecting on her own younger brother, who had drifted aimlessly after high school but is now fiercely studying for the Hercules certification, Seo-Yeong marvels at Castle’s true legacy. To her, the young CEO didn't just build advanced machinery; he constructed a physical infrastructure that revitalized the blue-collar middle class, giving real purpose and societal status back to the workers driving the physical world forward.
