At the end of the Warring States Period, seven heroes stood side by side, the world was in turmoil, and the war continued. The imaginary Qin Dynasty stands in the middle of troubled times. It is deeply trapped in internal and external affairs. The traitorous officials in the court steal the throne and bring trouble to the government. Strong enemies at the border are waiting and watching. The national power, military equipment, and agriculture are lagging behind other countries. The mountains and rivers are precarious. The country is in danger. The lives of ordinary people are like grass and grass. Their lives are precarious. Lin Beichen, a modern science student, accidentally traveled through these troubled times and became a down-and-out scholar in Xianyang City. He had no family and no support, living alone in a dilapidated temple. He could only survive by writing letters for others. He struggled to survive in the quagmire of the bottom, and he might be buried in the disputes of the troubled times at any time.
