After transmigrating to 210 BC, during the Shaqiu Incident, Gu Yan becomes Fusu. Faced with an edict ordering him to die, he refuses to take his own life and uses his modern knowledge to see through Zhao Gao and Li Si's plot to forge an imperial decree. He captures the messengers, seizes Wang Li, issues a proclamation to purge the court of traitors, and joins forces with Meng Tian to mobilize the Jiuyuan army and rescue the emperor. Su Jiao and She Jian come over to his side, while the Iron Eagle Elite stand guard. This coup that rewrites history will completely change the fate of the Qin Empire.
