Lin Yue, a graduate student in the Department of Modern History, traveled through time due to an accident and became a young Fusu (about 12 years old, around 240 BC, when Ying Zheng had not yet taken power and Lu Buwei took power). With the knowledge of later generations and modern thinking, he became a "hidden boss" who changed the fate of Qin and even China. On the surface, he appears to be a gentle young man, but in fact, he works step by step. He uses his advanced cognition to help Yingzheng eliminate internal and external troubles and unify the world. He also secretly starts the "Great Qin Version of the Industrial Revolution", which ultimately allows Chinese civilization to enter the steam age a thousand years ahead of schedule, creating a "super empire" that far exceeds history.
