The Doctor of Qin and Han History passed through his soul to Fusu, the eldest son of Qin who was demoted to the county. At that time, it was only three years before the Sand Dune Incident. He was well aware of the historical facts of Qin's fall. In order to avoid the fate of his death, he secretly planned. He relied on Meng Tian's frontier army, recruited Chen Ping and a group of talents, laid out intelligence secrets, secretly checked Zhao Gao and Li Si, and guarded against the old tribes of the Six Kingdoms and the Huns.
The First Emperor suddenly collapsed and false edicts were sent. Fusu refused and raised troops to Qingjun's side. At the same time, uprisings broke out all over the world, and Xiang Yu and Liu Bang fought for hegemony. He entered Xianyang, purged the traitors, compromised the shortcomings of Qin's laws, played the Hongmen Game, and recruited famous generals such as Han Xin. After several battles between heroes, Chu and Han were pacified and the troubled times ended. In the end, based on the Qin system, light corvee and low taxes, reformed the shortcomings of the Qin government, and reversed the history of the short-lived collapse of the Qin Dynasty.
