Wang Yuan, who traveled through time and became the magistrate of Chongquan County in the Great Qin Dynasty, his greatest wish is just to live a peaceful life and wait for death by relying on system rewards. Unexpectedly, due to a twist of fate, an unexpected trip to a birthday banquet made him unintentionally involved in the struggle for the throne of Qin and the subversion conspiracy of the remaining forces of the Six Kingdoms. His casual mention of sweet potato cultivation and the policy of extending favor orders were regarded as a model by the First Emperor Ying Zheng, and he became a new noble in the court. However, he was also regarded by Xiang Liang, Xiang Yu's uncles and nephews as the biggest obstacle to overthrowing the violent Qin Dynasty.
The power game in Xianyang Palace has not yet subsided, and the night assassination of Xiang's uncle and nephew has quietly come. Armed with the "overlord's courage" bestowed by the system and holding the "France's No. 1 Divine Weapon" staff, Wang Yuan was forced to switch from salted fish mode to combat mode. When he mistakenly beheaded Xiang Liang in a life-and-death duel and faced the wrath of Xiang Yu, the overlord of Western Chu, he was shocked to realize that he had already deviated from the path of peace and became the key fulcrum to leverage the fate of the Qin Dynasty. On the one hand, there is the reliance and suspicion of the First Emperor, on the other hand, there is the crazy counterattack of the remaining six kingdoms, and there is also the whirlpool of the battle between Fusu and Hu Hai for the throne. Can Wang Yuan escape from this treacherous Qin court game? How earth-shattering will the trajectory of history be changed due to the unexpected intervention of this Xianyu County Magistrate?
