"The Legend of Traveling Through the Qin Dynasty" tells the story of Su Ran, a college student in the Department of Modern History, who accidentally traveled to the Qin Dynasty while visiting an exhibition of cultural relics of the Qin Dynasty. When he first arrived in Xianyang, he quickly adapted to life with his familiarity with the history of the Qin Dynasty and got acquainted with Fusu.
In the court, Su Ran noticed Zhao Gao's conspiracy to tamper with the imperial edict and support Hu Hai's ascension to the throne. In order to help Fu Su stabilize his position, he followed Meng Tian to the border to fight against the Huns, and used modern military knowledge to help the Qin army achieve success. However, as Qin Shihuang fell ill, Zhao Gao framed Fusu for treason and recalled Fusu to eliminate him.
Back in Xianyang, the situation was critical, and Su Ran and Fu Su faced many crises. Finally, on the night of Qin Shihuang's death, Su Ran and Meng Tian led the loyal army to start a life-and-death contest with Zhao Gao. They successfully exposed his conspiracy, helped Su ascend the throne, changed the fate of the Qin Dynasty, and wrote a legendary story that traveled through time and space.
