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.
The issue of the mirrors was finally solved by Soraya.
She referred to the mercury brought from the laboratory and painted a bright layer of coating behind the glass, out of fear of poisoning risk from inhaling mercury vapor.
Light reflected much better on painted mirrors than on mirrors stuck with silver scraps. Roland set aside a batch of crystal glasses to make little mirrors and delivered them to every witch to keep. The witches were pleased to see their faces so clearly. Even the imperturbable Scroll smiled. Roland thought that the witches were still feminine in nature, even though they could not get pregnant.
