In the year of severe drought, Zhao Ergou entered the palace to survive and became a low-level eunuch. Due to a favor and the tragic death of his companions, he completely turned into a black man. He supported the prince's ascension to the throne by any means, and became the "Nine Thousand Years Old Man" who was in power but protected the bottom line of the people. After being jealous of the emperor and retiring to the cold palace, Qingliu took charge of the government and harmed the country, causing the rebels to besiege the city. When the civil and military forces of the entire dynasty surrendered, Zhao Jiuji, who was notorious as "the most traitorous eunuch in ancient and modern times", put on a python robe again, led hundreds of old and weak soldiers to launch a suicidal charge, and defended the country with his broken body, tragically dying for his country.
