At the Beginning, I Contracted a World-Destroying Dragon.

(Traveling (wearing) + lord + developing territory + Western fantasy + farming + multi-race + dragon) An innocent college student majoring in science and engineering was killed by a man who jumped from a building on his way to his first date with a girl. However, he accidentally traveled to a fantasy world similar to the Middle Ages, where there are beautiful elves, dwarves who are proficient in blacksmithing, goblins who are good at creation, strong and fierce orcs, etc. He pretended to be the dead son of a nobleman, but was framed by his brother and sent to a remote territory with difficult conditions. But unexpectedly signed a symbiosis contract with an "evil" dragon that once almost destroyed the world. Grow potatoes and sweet potatoes, burn bricks to make cement, build toilets, buy werewolf slaves, ask dwarf masters to forge weapons, and manage the territory prosperously. In the process, she also met many confidantes, a wise human female magician, a female paladin who believed in justice, and an arrogant but kind-hearted female elf archer. However, as the power develops, many truths are slowly revealed. . . . . . .
