The fake eunuch Xing Bang traveled through the Gaowu World Palace and activated the Fenghua Baojian system. He dealt with the queen and Mrs. Fanghua, and relied on the system to reward magical skills and experience to grow rapidly, rising from a handyman in Yeyouting to a eunuch in charge. He rescued the prince's biological mother, quelled the epidemic, investigated unsolved cases and brought down powerful officials, and was awarded the title of Marquis to take charge of the West Factory. After gaining insight into the emperor's purge conspiracy, he united with the Wu clan to integrate the Xiao family navy, Zhennan army and the He family's old troops. In the end, he led 100,000 cavalry to reverse the situation in the imperial city and overthrow the Hunjun. The story ends with Xing Bang ascending the throne as emperor, starting a new dynasty chapter with all the beauties, and completing the counterattack from a young eunuch to the king of the world.
