The world is gripped by an unprecedented crisis: a mysterious illness sweeping across the globe has left millions in an inexplicable coma, with no known cause or treatment in sight. Investigations eventually point to a startling discovery beneath the ice of Antarctica—a vast underground realm that has never before been seen by human eyes. This hidden world teems with bizarre creatures and is rich with untapped natural resources, drawing waves of fortune-seekers eager to claim its riches for themselves. Yet among those who venture into this uncharted domain, Shigure Daniel Kai carries a very different purpose. Rather than chasing wealth, he is driven by the desperate hope of finding a cure for the afflicted. What sets him apart goes beyond his resolve—he alone appears to be naturally immune to the illness, a rare gift that may make him the key to humanity's survival.
