In 1996, Mei Kun, a migrant worker in the workplace, died suddenly of overwork, and his soul was transformed into the prince of Qin who was ostracized by the powerful on the eve of the death of Qin. Using history books as a basis and modern survival instincts, he killed Zhao Gao, guarded the pass, and continued the lifeline of the Qin Dynasty. When the Six Kingdoms were restored and Xiang and Liu came together, the Xiongnu took advantage of the unprecedented snowstorm to invade the whole country and invaded the south. The strange people on the coast landed to massacre the city. He had to save China first and then settle the world in the triple chaos of the war between the kingdoms, the barbarian cavalry and the sea monsters advancing westward. In addition, the Western Qiang Rong took advantage of the vacancy to harass Qin, and the southern Fujian and Yue took advantage of the opportunity to harass Chu.
