Introduction: I like reading. I like games. But I never expected to be summoned to another world—especially not by a Demon Lord.One moment, I was at home, and the next, I was standing before Zareth Malgrim, the 14th Demon Lord, who expected me to fight against humanity in a war I knew nothing about. No overpowered magic, no divine blessings—just me, an ordinary guy with no mana.Except… I did have something. A skill I didn’t understand. A skill that lets me learn anything at an unnatural speed. And the Demon Lord unknowingly gave me another—one that pushes my body past its limits at a terrifying cost.Thrown into a war between humans and demons, I have no choice but to fight, adapt, and survive. Whether I side with humanity or stay with the demons… that’s a choice I haven’t made yet.But first, I need to make sure I don’t die.What to expect:Weak to Strong Progression – No instant power-ups. The MC starts weak and must train, learn, and adapt to survive.High-Stakes Combat – Fights aren’t just about power but strategy, endurance, and risk.A Dangerous Power System – Every ability has a cost. Overuse means severe consequences—or even death.Morally Grey Choices – Not all humans are good. Not all demons are evil. Which side is truly right?Intricate Worldbuilding – Kingdoms, floating demon castles, divine blessings, and a war centuries in the making....
