Rebellion of the Eight Kings: the Last Lord

He traveled through time and became Leon von Hohenzollern, the second son of the notorious Marquis of the Empire. In a desperate situation, he bound to the "Evil Young Man System" and danced on the edge of a knife. He dealt with his genius fiancée Alyssa, his cold-faced aunt, and various forces at the Royal Capital Academy. He relied on modern thinking and systematic tasks to survive, but secretly used the "1888-style rifle" as a blueprint to conspire to create a force that would subvert the times. At the same time, Alyssa went to the north for an internship, encountered an orc raid, and established a life-and-death bond with the demi-human brother and sister who had awakened their bloodline. She risked her life to investigate, and was shocked to find that the orc war lord was leading an army to the border, intending to invade the area. The Sword Castle Fortress was in danger, and she and her companions brought back shocking news during their bloody escape. Two threads of fate quietly intertwined in the storm. Leon accumulates the fire of change in strategy and technology, while Alyssa tempers the edge of the silver moon in the flames of war and responsibility. The war drums in the northern border of the empire are already beating, and the undercurrent in the royal capital is becoming more and more turbulent. A villain's counterattack ambition and a genius's path to defend the country are about to be involved in a torrent of iron and blood sweeping the empire.
