Cheng Yan travels through time, only to end up becoming an honorable prince in the Middle Ages of Europe. Yet this world was not quite as simple as he thought. Witches with magical powers abound, and fearsome wars between churches and kingdoms rage throughout the land. Roland, a prince regarded as hopeless by his own father and assigned to the worst fief, spends his time developing a poor and backward town into a strong and modern city, while fighting against his siblings for the throne and absolute control over the kingdom. Join Roland as he befriends and allies with witches and, through fighting and even farming, pushes back invaders from the realm of evil.

Roland stood on the balcony on top of the command room of his boat and felt his heart stir with pride as he watched his fleet of boats lined up behind him.
Besides the flagship, the Roland, all the other boats were slow and clumsy concrete boats. However, with more than ten of them in a fleet, they still looked magnificent. The massive fleet puffed long trails of white smoke out of their chimneys and parted the river as they crashed through the waves, and they seemed to be completely unstoppable.
The gunboat was apparently the fleet's main attraction—its towering bridge and sleek appearance separated it from ordinary sailing ships and concrete boats. It dominated the inland rivers with its weapons, including a 152mm main cannon and two Mark I machine guns, custom-made high-pressure steam engine, and a propeller driving system that enabled it to reach a speed of 12 kilometers per hour.
