As a Demon Lord, I Make Game Dungeons in Another World

Lin Fei came to another world by accident. Here, people awaken their own class at the age of 15: [Warrior], [Assassin], [Monk]. As someone who transmigrated, Lin Fei awakened a one-of-a-kind class: [Demon Lord], and gained the ability to create dungeons. Let me bring this world a little more fun. And so: Dungeon: Winter Is Coming, with blades standing tall above the kingdom. Dungeon: The Fulong Tree, where the Rock Dragon King shakes the earth. Dungeon: The Descent of Divine Sin, as the gospel of a false god blankets the world. Come, for power, for riches... Everything is waiting inside the dungeons.
