A walking grimoire of forbidden power: pages inscribed with the blood of heaven's enemies, binding woven from the sinews of earth's haters, cover carved from the skin of humanity's cursed. His existence defies natural law—a living embodiment of darkness's dominion. When celestial brilliance collides with infernal sovereignty, the path to supremacy demands absolute ruthlessness. The Heavenly genius has met his match in the Heavenly demon, and only one will emerge unchanged.
