In the twenty-fifth year of Qianlong's reign, He Lianzhao, the son of the Han army flag-bearer, entered the palace with his mother's enemy and unexpectedly became the imperial guard. He originally wanted to find out the truth behind the murder of his biological mother, but he was involved in the power vortex between the Minister of Military and Aircraft and the Ministry of Internal Affairs. On the same day, Yehenara Yuning, a noble girl from Manchuria, was ordered to be drafted. She hid the "Supplement to the Agricultural Policy" left by her father and wanted to find a way to survive for the people of the world in the deep palace.
Two people who were not supposed to meet made an oath under the red wall of Qianqing Palace to "respond internally and externally and implement the New Deal." However, when Zhao'an was promoted from the military commander Zhang Jing to a feudal official, and Yu Ning was promoted from a nobleman to an imperial concubine, they discovered that their biggest enemy was not each other, but the Emperor Qianlong who single-handedly promoted them.
This is an epic about loyalty and betrayal, family feud and national fate. When imperial power and conscience, love and attitude finally have to be chosen, who can pass through the Nine Palaces and reach the end of the Tianqu?
