Ying Zichu traveled through time and became Qin Shihuang's most disliked concubine, dormant among the ridicule of everyone. He used modern management knowledge to improve agricultural tools, rectify the military supply chain, and design a beacon early warning system, gradually gaining the attention of the First Emperor. After the death of Qin Shihuang, faced with the critical situation of Hu Hai usurping the throne and Zhao Gao disrupting the government, Zi Chu raised troops from remote fiefdoms and put down the rebellion with overwhelming force, and finally ascended the throne and ushered in the prosperous age of New Qin.
