"They gave me a death sentence. I turned it into a power source." In a world of Absolute Zero, heat isn't a right—it’s a debt. Sky John spent his life building the heaters for a city that eventually threw him into the frost to die. They called it 'resource management' but it was a mistake. Cast into the barrens where the laws of physics are breaking, Sky almost froze to death but his Eternal Hearth System allows him to do the impossible: devour the cold to fuel his own evolution. While the elite huddle in bunkers fighting over Heat Credits, Sky is outside transmuting the killing frost into Sol-Steel skin and a thermal-kinetic pulse. He was a Tier-Zero architect but now, he’s a living singularity. Sky isn't just coming back for his stolen designs—he’s coming to show Supervisor Vance that the 'Great Freeze' is actually a harvest. The reapers are at the door, and Sky is the only thing hot enough to melt them down. The bunkers are cold. The Sun is coming. And the bill is finally due.

Everyone in Chicago thought Keith Cross was nothing—a discarded war hero turned human blood bank for his in-laws. His wife called him a leech, her mother demanded he donate or die, and her new lover promised to "drain him dry." But what they didn’t know? That “worthless freeloader” they mocked… was the Miracle Doctor they’d been desperately begging to save their dying son. “You think you can throw me out like trash?” Keith says with a slow, deadly smirk. “You’ve been living off my charity this entire time.” When Keith flashes his black VIP card, the world shifts. Elite restaurant managers fall to their knees. Security guards bow. And his ex-wife? She drops to the floor, begging for mercy after publicly calling him a busboy in disguise. “You said I was a blood bag,” Keith says, towering over her. “Funny. You never asked whose blood ran this city's veins.” She called him weak. He became untouchable. Now he’s back—to take everything they stole, and leave them gasping in the dust of his name.

In a world where cultivation is the sacred path of body and soul, Lin Cang possesses neither. He awakens in the body of a young man with no meridians, no dantian, and no soul-sea—yet he lives. Shunned by the natural laws of heaven and earth, unable to walk the orthodox path, Lin Cang discovers a different way: the Dao of Form. Through mysterious patterns and ancient blueprints only he can perceive, he begins to reshape his own body—piece by piece, refinement by refinement—into something the world has never seen. In a realm of righteous sects, blade-wielding prodigies, and soul-bound cultivators, Lin Cang must conceal the truth of his existence while carving out his own legend. But the more he transforms, the more a question begins to stir: if he was never truly human to begin with, what will he become by the end? A tale of identity, power, and reinvention, The Puppet Dao blends classical cultivation adventure with a unique journey of self-crafted evolution. The path to immortality is written in flesh and spirit—but Lin Cang will write his in wood, will, and wonder.
