Release That Witch
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.
When Roland received the report jointly written by the commander of the First Army and the chief of the General Staff, he immediately thought of the spy movies he had watched.
This was apparently a very feasible plan.
He even thought more about the plan than Edith.
Spy was an ancient profession, and it had various names in different times, but the spy Roland was familiar with were those in WWI and WWII. Early intelligence collection was simply a two-way communication without a systematic organization. As the government tightened their control over people, spies and agents found it increasingly hard to escape the scrutiny, and that was the time when a well-organized system was established.
This also meant that in a feudal country ruled by nobles, spies could be anywhere. Once those agents received some professional training and learned cunning tricks to protect themselves, they would never be found even if the whole city was turned upside down.
