The Jin Dynasty was a dynasty with a real historical framework, but with elements of magic and fantasy added - for example, there were ministers practicing mystical arts in the court, legends about ancient beasts spread on the border, and there might even be mysterious relics or items hidden from other dimensions (sci-fi level).
- Core conflict: As a foreigner, Gan Daye needs to survive in an unfamiliar power structure. Through "calculation" (using information gaps, converting modern knowledge into practical technology, and leveraging conflicts between various forces), he gradually climbs the ranks, and finally obtains the title of county king. In the process, he will be involved in magical events (such as fighting against a magician) and fantasy adventures (such as exploring secret realms to gain power).
