Apocalypse All-Class Mage

When blood-red clouds swallow the sun, the true apocalypse begins. In a world where blood rain becomes the ultimate elixir and humanity serves as fertilizer for monsters, one mage discovers a chilling truth: he's been following footsteps from the future. Armed with mysterious human skin parchment—an obituary from hell itself—he must master every magical class to survive the scarlet end times. But in this brutal new reality, power comes at a price, and the line between savior and monster blurs with every spell cast.
