Philip never expected his new life to be so… complicated. When a tragic accident in the modern metropolis of Bortinto abruptly ends his struggle for survival, he wakes up as the scandal-ridden heir of a ducal house in a world where magic and science coexist. Any fantasies of an easy, heroic life vanish the moment he realizes that the estate that he is tasked with managing is drowning in debt, and his reputation has been shredded by rumors involving his predecessor’s broken engagement to the socialite Lady Rosetta—the granddaughter of a prince.Even as he scrambles to rebuild his estate’s fortunes—grappling with contaminated land, mounting debts, and shrewed industrialists—he unearths troubling secrets about the original Philip’s heartbreak and suicide. A dark, hidden force seems intent on wiping him out for an unknown reason. As conspiracies emerge linking Lady Rosetta’s departure to these shadowy machinations, Philip struggles to separate ally from adversary, not knowing why this power in high places is so bent on destroying him.Meanwhile, the realm teeters on the brink of monumental change. Technological and social revolutions collide with century-old magical traditions, and war drums thunder on the distant borders. Armed with his modern knowledge of finance—now fused with the kingdom’s burgeoning industrial innovations—Philip attempts to ride the trends and transform his estate into a beacon of prosperity and secure his heirship to the ducal title. Yet each small triumph only attracts more enemies.Tasked by the System with cultivating a supernatural entity while uncovering the real reason behind Lady Rosetta’s canceled engagement and the original Philip’s tragic end, he must also shield those he grows to care about from the looming threats. Will he harness the synergy of magic, technology, and commerce to steer his estate toward greatness, or will malevolent forces quash his second chance at life? Will his second chance at life end the same tragic way as his first?

For unknown reasons, he finds himself transported to a parallel world's Japan, unexpectedly taking over the body of a soon-to-be high school student who had died accidentally. Surprisingly, he did not inherit any memories. However, the first challenge he faces upon arriving here is a language barrier...Just as he struggles to communicate with his new family, a heavenly voice arrives: the black technology system has been activated, and the initial item—translation konjac—has been distributed.This is the story of someone with above-average intelligence but almost no physical strength in the Classroom of the Supreme Power.
