The original star of Wuzhang has fallen, and Chen Yu, a master of history who is familiar with machinery and agriculture, has his memories merged and reborn to the end of the Warring States Period when Ying Zheng first ascended to power. He went dormant in the countryside under a pseudonym, and first showed his talents by dredging and controlling floods in Xiye Village. He inspired Li Si, who was still seeking progress in a poor family, with his political views of taking advantage of the situation and reassuring the people. The two became acquainted through grassroots practical work. Chen Yu relied on a thousand-year vision to improve farming, introduced high-yielding crops to improve the crop rotation system, and used grassroots drainage to explore the rules of government governance, clearing the grievances of his father Zhuge An, and hiding his own edge that transcended the times. Undercurrents in the court are surging, the old troops of the Six Kingdoms are waiting for opportunities, and hidden dangers such as Zhao Gao and Hu Hai are hidden. Chen Yu assisted Yingzheng in stabilizing internal affairs: he improved the system of three ministers and nine ministers, piloted the structure of three provinces and six ministries, strictly regulated laws and cared for the people; he recruited talents and recruited famous generals from Chu and Han such as Xiang Yan, Han Xin, and Zhang Liang to resolve old conflicts; he upgraded iron smelting and gunpowder technology to consolidate armaments, and opened up trade routes in the Western Regions to steadily expand the territory. He abandoned short-term utilitarian achievements, insisted on in-depth cultivation of education with the same writing and the same track, used domestic affairs to consolidate his foundation, and steadily expanded outward, avoiding the old path of the Qin Dynasty's harsh rule that soon led to its demise. In the past, Marquis Wu's original intention to calm the people and help the world met with the talented and broad-minded First Emperor. They complemented each other with literature and military force. He controlled the Xiongnu in the north and the Baiyue in the south. He extended the territory of China to the west and spread the Chinese governance outward along the trade routes. Farming infrastructure, court games, and expeditions to expand the soil are unfolding step by step. Watch the wise men of later generations take root in the Qin Dynasty, reverse the established outcome of the destruction of the second generation, and create a prosperous Qin Dynasty that lasts for eternity.
