Regis suddenly wakes up in a bewildering and nightmarish situation. He's soaked and disoriented, confined within a cramped cage made of metal bars. To his shock, he realizes that he's inhabiting the frail body of a ten-year-old slavey boy.

As he grapples with this bizarre reality, he discovers that he's surrounded by fellow slaves enduring the same harsh conditions. Their existence is marked by hunger, cruelty, and relentless work in dimly lit, musty tunnels. Regis's own body bears scars from abuse and malnourishment, a testament to the torment he shares with his fellow captives.

Amid this grimness, Regis stumbles upon an unexpected power tied to the concept of "fortune." He starts to unlock his hidden potential. However, as hunger gnaws at him, a persistent cough plagues him, and a sense of urgency grows, he faces a critical dilemma. How can he break free from this wretched life and navigate a world filled with danger, cruelty, and mysterious systems that defy understanding?
