Iron-Blooded Era

The disaster has not yet come, but purgatory has already occurred. The world has a unified language, but it has never unified its destiny. The rich and powerful live behind high walls, while the poor are trapped in the mire. Oppression and poverty go hand in hand, and resistance becomes a blood sacrifice. When the world-destroying fire fell and the black metal virus swept across the earth, the cracks in the old order were completely torn apart. A slum boy awakens the power of black bones in a desperate situation, casts his body with iron, and proves his way with blood. The injustice of the old world will be reshuffled in the iron blood and disaster.
