At the end of the Ming Dynasty, the 9,000-year-old eunuch Wei Zhongxian took advantage of Emperor Tianqi's critical illness to recruit martial arts weirdos, form cliques for personal gain, kill loyal people, and attempt to seize power and usurp the throne. Tianqi's younger brother Zhu Youjian is naturally smart and ambitious. With the help of the loyal minister Wu Fenglou and his knights Wuyue Sanniao, they launched a desperate struggle with the traitor and his best friend Jin Yiwei. The whole book begins with Wu Fenglou studying martial arts in Songshan, Yingchoujian mistakenly rescues Wei Yinping, the daughter of his enemy Wei Zhongying, and goes through the sudden change in Hangzhou, the death of his father and the destruction of the family, the devil's cave to save his mother, the marriage in trouble, the emperor's mausoleum in Fengyang Mansion to save King Xin, Yuan Jiabao's enmity due to love, and... Lively stories such as Tian Yaozi playing a witch and two ghosts causing trouble in Xuzhou finally enabled Wu Fenglou and Wuyue Sanniao to break through the layers of fog surrounding the female demon prince Hou Guoying, penetrate into the enemy's heart, and launch a more intense struggle with the traitor Wei Zhongxian.
