Traveling Through the Middle Ages: It Turns Out I'm Not the Only One Traveling Through the Middle Ages

[Western Fantasy + Time Travel + Overhead + Sword and Magic + Easy] Mercenary Han Han accidentally traveled to a different world of swords and magic. Inexplicably, he became a powerful nobleman. He also had the gold coins (legacy) of Lao Deng (a traveler from a higher civilization) waiting for him to explode. He thought that his future life as a lord would be just fine. It was training soldiers, developing territory, and slapping the dwarves in the mountains from time to time. Little did they know that there were millions of orcs gearing up in the wilderness of the northwest, and there were also powerful neighboring countries in the north that had exploded with Laodeng gold coins and were peering at the fertile land of the kingdom.
