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.
The effect of the live-fire artillery exercise exceeded Roland's expectations.
He had indeed got what had paid for. In the last round of explosion, he had ignited 70% of the total black powder reserves and had got an explosion as intense as that of the roadside bombs in the modern world where he had lived before. While the soldiers had been burying the powder, he had had a sudden thought and had mixed some aluminum powder with the gunpowder. As a result, the fireball of the explosion had become even more bright. The moment it had shot out of the ground, it had looked a bit like the rising sun.
