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 third witch was Hummingbird. She was small, just as her nickname depicted. She acted more reserved than the other witches when Roland asked about her ability. She just reached adulthood this winter and was a cute girl with symmetrical dimples, a delicate face and a sweet soft voice.
Her ability was Object Lightening, which meant that she was able to greatly lower the weight of an object once she put her magic power into it. According to her description, the weight of an object would be close to zero. Roland asked her to demonstrate it with his teacup and found that the teacup almost floated in the air—that was to say, its weight was close to that of air. Of course, in the eyes of people in that era, air was weightless.
