Three modern time travelers were involved in the troubled times of the late Qin Dynasty: the Huaxia clan rebelled with Yingzheng's edict of "establishing Fusu and passing on the Huaxia", while brothers Li Zongping and Wang Kun used modern knowledge to seize Huainan. China reformed its military system and established special warfare brigades and field art teams. Zhao Ling'er passed on the imperial edict to unite the people's hearts. The army supported the people and stocked up food and recruited talented people. Zhang Liang and other celebrities came to join the army. Zhao Hu and Qian Bao assisted in both literature and military affairs. They gradually became a powerful force that the people wanted.
Xiang Yu destroyed the cauldron and destroyed the boat, which shocked the giant deer. Li Zongping and Wang Kun brutally sacked Xianyang and massacred the Qin clan. The Qin army in the north collapsed and Zhao Tuo separatist power in the south. China took advantage of the traveler's forward-looking vision, slowed down its troops and marched westward to watch the internal fighting among the rebels. When Xianyang was broken and the traitors were killed, they then led one hundred thousand elites to advance towards Xianyang with the power of the imperial edict. Various forces are vying for power in the Central Plains. China uses benevolent government as the foundation and a strong army as a shield to open up a path to peace in troubled times. The final competition outside Xianyang City is about to begin.
