Su Wen opened his eyes and found himself lying in the military camp in the northern border of Great Qin, taking over Fusu's identity.
He is the eldest son of Qin Shihuang, and he is a military supervisor who has just been demoted to Shangjun - also a fate destined to end three years later in the history books.
The shadow of the Sand Dune Incident hangs overhead, and Zhao Gao's conspiracy is brewing in Xianyang, and he only has 300,000 hungry and cold garrison soldiers and a broken Great Wall in his hands.
Fortunately, the civilization dimension upgrade system was activated.
From the curved shaft plow to stirrups and saddles, from military medical training to papermaking and printing, from improving Qin's laws to establishing the Imperial Academy, he spent a thousand days and nights to bring the Qin Dynasty back from the brink of collapse.
When the Xiongnu went south, his cavalry had been equipped with new harnesses and long steel poles.
When famine struck, his experimental fields were filled with Champa rice and potatoes.
When Zhao Gao's secret envoys came to the northern border with Jiao Zhao, what was waiting for them was not Fusu who knelt down to receive the imperial edict, but the swordsman who took it down with his backhand and killed him in public.
After the dust settled, Fusu stepped into Xianyang Palace, and in front of the civil and military officials of the court, he took the imperial seal from Zhao Gao's blood-stained hand and turned to look at his father on the dragon throne.
The fate of Great Qin begins to be rewritten today.
