Yun Yi traveled through time and became a prince of the Yong Dynasty. However, his empress mother actually passed the throne to her nephew and made him an idle vassal king. Let the feudal king be the feudal king. Anyway, life is only 30,000 days, so eating and drinking is not bad. But before he had lived a good life for a few days, he encountered the new emperor who wanted to cut off his vassal status and vowed to take him to the capital for questioning. It turned out that he had long become a thorn in the new emperor's eye. Fortunately, he was an arms expert before time travel and was proficient in the manufacture of various guns. Since he couldn't become the vassal king, he should raise an army to appease Nan. You have an iron horse, but my torrent of steel has never scared anyone!
