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.
Apart from the upgraded heavy machine gun, Roland also planned to develop a bolt rifle which would have a mid to long shooting range. He did not need many, a mere hundred or so would suffice. The rifle would have the same caliber as the heavy machine gun, and could be easily transformed into a sniper rifle by simply installing a gun sight.
In this way, he could continue to manufacture revolving firearms and black powder bullets without a huge waste of the products.
During a battle, soldiers could use field artilleries to suppress enemy forces within 800 to 1,000 meters and heavy machines guns 500 to 800 meters. Snipers could take care of enemies in less than 500 meters, and revolving rifles could be used to clear out enemies within the last 200 meters. Therefore he could, in theory, make sure every inch of the battle field was covered.
