Ye Zhao, the daughter of the general on the edge of the town, and her whole family were executed for "collaborating with the enemy." She disguised herself as a man and became an undercover Jin Yiwei to enter the palace, trying to find out the truth. After entering the palace, she discovered that the astronomical observatory deep in the palace concealed the remains of an alien civilization. The star map code was not only related to the struggle for imperial power, but also involved the ancient contract of interstellar civilization. Ye Zhao used star map clues to fight back against his enemies (concubines, eunuchs, and traitorous generals) during palace battles. At the same time, he cooperated with Shen Huaijin, the consort in charge of astrological observation, to expose the Queen Mother's conspiracy to manipulate the stars to tamper with the national destiny. He finally cracked the star map code, prevented the resurrection of alien civilization from destroying the human world, and cleared the grievances of his family.
