After dedicating nine long years to Dungeon and Stone, a role-playing game that no one has ever managed to clear, Hansu Lee finally arrives at the final boss’s dungeon. However, the moment he opens the gate, a message appears declaring that his tutorial has been completed. Before he can process what is happening, he suddenly awakens in the body of Bjorn Yandel, a real barbarian living inside the game world itself.

Now trapped within the world he once played, he must adapt to its harsh rules and survive as a true inhabitant rather than a player. An unpredictable and thrilling journey begins as he strives to navigate this brutal reality and abide by its laws.
