Chen 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.
Release That Witch starts rough stylistically because of the translation, but somewhere within the first few hundred pages the momentum becomes addictive. The premise feels far more original than the average progression web novel: instead of pure cultivation or arbitrary power scaling, the story is driven by industrialization, engineering logic, politics, logistics, and applied scientific thinking. The protagonist’s real “cheat” is not brute force but knowledge transfer — introducing modern concepts into a medieval-magical world and watching society reorganize around them. What makes the first ~1000 pages compelling is that characters usually behave rationally within the rules of the setting. Problems are often solved through infrastructure, experimentation, governance, and resource management rather than pure plot armor. The witches also feel more like strategic assets and human beings than decorative archetypes. Despite repetitive stretches and uneven prose, the worldbuilding loop becomes extremely hard to stop reading because every advancement has tangible downstream consequences. It feels almost like reading a civilization-building simulator disguised as fantasy.
Picked it up after watching the anime and discovering that the anime will never likely be finished. I had rock bottom expectations going into this book: it's a web novel, it's fan translated, and it's an isekai. And yet I enjoyed it quite a bit. The translation is still very rough but I can tell the translator really tried with the descriptions, and sometimes succeeded. The plot moves at a very brisk pace and I was seldom bored. I was also pleasantly surprised at the character growth and how much more depth certain characters had. The real star of the show is a setting which, despite the frequently unintentionally hilarious naming conventions, is very well though out and has several interesting mysteries going on at once. The application of science with magic to a medieval setting, kickstarting an industrial revolution using magic as an accelerant, was quite fun as well.
The book is not without problems though. For once it had a rather distracting and a bit creepy 'male gaze' for lack of a better term remarking lasciviously on every female character's appearance. It doesn't quite fall into the worst of harem tropes but it's definitely adjacent. Also the references to 'our world' media (such as League of Legends or Gwent) I found more annoying than fun. Finally the translation really is not good; I almost stopped reading early on because I found it so bad. I'm glad I pushed through though because the story and setting was worth it.
