The Lost Primordials: The Thunder Bastion

Born a slave in the deepest mines, Lei Yuan knows only darkness and pain. When a structural collapse buries him alive, the empire above seals the tomb, leaving him and his crippled brother to die in the dark. But deep within the earth, an ancient heartbeat stirs. A forgotten bloodline awakens—the thunder of the Kui Niu, a power that rivals the gods. To survive, Lei Yuan must carve his way out of the grave. Bound to a cold-blooded, exiled healer by a fragile alliance, and hunted by the Emperor's elite, he will ignite a rebellion that shakes the heavens. He will become the God of Thunder. But in this world, power has a price. And the price... is everyone he has ever loved. A dark, tragic progression fantasy. Every victory is paid in blood. Every step forward leaves a grave behind.
