Li Yu was demoted to the place of death, "Luofeng City". There were 100,000 enemy troops outside, and the guard Wang Mang inside forced the palace to demand military power. Li Yu activated the system and triggered the tyranny value by "trapping the enemy's troops to persuade them to surrender" and summoned the "Xuanjia Army" to massacre the enemy overnight. Later, he used systematic insights to expose Wang Mang's crime of collaborating with the enemy and cooked him in public (to shock the three armies). Li Yu took advantage of the victory and returned to the army with King Qin. On the way, the supervisors sent by the prince accused the prince of collaborating with the enemy. In the capital, Li Yu used the system's "people's poison" to make the prince's gangsters turn against themselves. Finally, he forced the prince to go to the palace, cut the prince into pieces, ascended the throne and proclaimed himself emperor, starting the path of iron-fisted reform.
