Gongsun Xuan, the son of Gongsun Du, used his advanced knowledge to buy land, purchase refugees, innovate industries, develop agriculture, animal husbandry and fishery, find beautiful women and recruit powerful generals, cultivate literature and prepare military affairs, and establish shipbuilding industry... Starting from the Liaodong strategy, he gradually controlled Xuantu County, Lelang County, Daifang County, Goguryeo, Sanhan, Japanese slaves and other countries. During the Yellow Turban Rebellion, he relied on Youzhou cavalry to defeat Zhang Liang, Zhang Bao, and Zhang Jiao, and was awarded the title of General of Hussars, Marquis of Xiangping, and Prefect of Liaodong. He also put down the rebellion of Erzhang, surrendered the Wuhuan tribes, and was promoted to the Mu of Youzhou. The Ling Emperor dreamed of it, and the nineteen princes tried to figure it out, and they cleverly intercepted Dong Zhuo's large amount of gold and silver. Later, during the period when the princes were fighting for hegemony, they defeated Yuan Shao, Liu Bei, Zhang Yang, Wang Kuang, Yuan Shu, Liu Biao, Sun Quan, Shi Xie, Liu Zhang and other princes, and took over all the land of the Han Dynasty.
Then he conquered Xianbei in the north, conquered the Western Regions, Kushan, Parthia, and Rome in the west, and conquered the barbarians in the south... Thus, he conquered the entire Asia and the Australian continent, and finally became the unprecedented emperor of the ages!
