Devouring Dragon Heir Novel

After years of backbreaking labor as a porter in a world dominated by magical beasts and powerful Hunters, he had long abandoned hope for the cheat ability he dreamed of from the countless novels he'd read. When he finally earned a chance to obtain a skill, disaster struck—a dungeon swallowed him whole, and he barely survived the ordeal. In that moment of desperation, the Supreme Dragon System awakens within him, exposing a devastating revelation: the heavens had conspired against him all along. Every hardship, every year of suffering was nothing but their cruel manipulation. His name is Klaus, and his fury knows no bounds. With newfound power coursing through his veins, he makes a thunderous vow that reverberates across all realms: "The heavens schemed against me, I will shatter the heavens!" This is Klaus's journey of vengeance against divine forces, rising from betrayal to claim ultimate power.
