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.
To master how to host an incarnation ceremony of God's Punishment Army was essential to the pope. When Mayne had taken over the ancient book of God's Punishment from His Holiness O'Brien, it meant that he had been qualified to be the next pope.
Mayne had learned all that was written in the book thoroughly. He knew that to create a man of God's Punishment Army they needed to sacrifice a witch, whose blood would be blended with a God's Stone of Retaliation before being injected into the man of the Judgement Army. Despite that the process had been improved several times over centuries, the essence had not changed—the number of witches limited the total number of the men of God's Punishment Army, and the will of the Judgement Army significantly determined the success of the incarnation.
