Ying Changsheng traveled through time and became the youngest son of Qin Shihuang, activating the national destiny system. He planned to eliminate Zhao Gao's party members, promote high-yielding crops, improve ordnance, and send troops north to attack the Huns. In the court, he acted decisively and implemented the New Deal; in the palace, he had many interactions with the imperial sister Ying Yue'er, and daily interesting things happened constantly. Deciding national policies internally and expanding territory externally, he vowed to create a prosperous and powerful Qin Dynasty with his own hands.
