If Fusu Does Not Die, Da Qin Will Not Perish.

A young man in modern scientific research accidentally traveled through time and became Fusu, the eldest son of the Qin Dynasty. He was imprisoned in a prison for speaking out and remonstrating. He relied on modern knowledge to see through the hidden dangers of the Alchemist's elixir, and gave advice to the First Emperor to resolve the crisis. After gaining trust, he went to Shangjun to take charge of the Great Wall and Border Guard Army, uniting the Meng clan to recruit talents. Internally, the people's livelihood was improved, corvee reduction was reduced to appease the people, externally, border defenses were strengthened to resist foreigners, and the Qin army's combat power was steadily increased. He saw through Zhao Gao and Li Si's conspiracy in advance, put down the traitors in the court, implemented new policies that benefited the country, and devoted himself to repairing the shortcomings of the Qin Dynasty and protecting the long-term stability of the country.
