Lin Che, a graduate student in the Department of Modern History, accidentally traveled through time and became an orphan of the Mohist family who was to be executed in the Qin Dynasty. He was also bound to the "Reverse Qin Conquering the Sky System" - if he failed to complete the mandatory task of fighting against the Qin Dynasty and unifying the world to destroy Hongjun, he would be obliterated!
In order to save his life, he denounced the tyranny in the execution ground and escaped. He relied on the improved mechanism of system exchange to subdue the remnants of the Mohist family. He also withstood the pressure of the system's time limit and intercepted grain and grass to save the people. He resisted the decree and refused to repair the Lishan Tomb. Step by step, he rebelled against his ministers in Surabaya, forcing Qin Shihuang to go from wanting to get rid of him quickly to becoming a special "king and minister" who relied on his abilities.
The system pushed him to stop: make gunpowder, build engineering institutes, and lead the Qin army's scientific and technological fleet to pacify Japan; connect the Western Regions, conquer the South Ocean, and cross the Atlantic Ocean to capture the Americas to help the Qin Dynasty unify the world; he must also activate the laws of human nature to fight against Hongjun Daozu, who regards the mortal world as a heresy.
From a rebellious minister who was forced to resist, to a leader who shouldered the responsibility of human civilization, Lin Che was "forced" by the system, holding the Holy Sword of Humanity in his left hand and the heavy weapon of science and technology in his right hand. Finally, he stood side by side with the First Emperor, slaying Hongjun, breaking the way of heaven, and leading Chinese civilization towards the sea of stars.
