Reborn: Pioneering the Medieval World

When Chen Fan wakes up, he's locked in a medieval slave pen and nearly dragged away as a slave. At the critical moment, the All Things Exchange System unlocks: points can be traded for any supplies from other worlds. His starter pack contains a black pistol. He blasts open the iron gate, slaughters the soldiers, and escapes alive. From then on, he uses the point system to master the rules and embark on a strange adventure through the medieval world.
