introduction: Dan wasn’t expecting to wake up in a medieval village riddled with disease, poverty, and giant, acid-spitting spiders. One minute, he was in his apartment, avoiding responsibilities like a normal person—the next, he was being shoved into a half-collapsed house and told to deal with the local pest problem. No magic. No overpowered abilities. No chosen hero nonsense. Just one skill: Buy & Sell. At first, it seemed useless. Who needs an overpriced fantasy Amazon store when they’re dirt poor? But when Dan discovers he can sell anything—including dead monsters—his outlook starts to change.
