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.
After hearing the description of the Soul Battlefield from Isabella, Nightingale began getting depressed. "Do you mean that you also don't know how to make His Majesty wake up from the coma?"
She shook her head. "This is unprecedented, and I have no idea how to deal with it... But Zero was absentminded for a while when she was devouring Garcia. At that time, she explained that she had found some interesting things in Garcia's memory and so it took her a long time. Zero has had a more complicated life than anyone else, so if Roland wants to accept these parts of Zero's memories, it may take some more time. But as long as he's alive, he'll wake up naturally."
Nightingale could not be sure whether this was true or not, but she could tell that Isabella did not lie. At least these conjectures were heartfelt thoughts from Isabella.
But Nightingale also knew that the situation was not at all optimistic.
