Qing Pheasant of the Fox tribe entered the mortal world under the pseudonym Qin Shen. Her sister entered the palace as a concubine to seek her love, but she fell in love with the gentle and virtuous waste queen in the palace. After the deposed queen committed suicide to protect her sister, Qingzhi secretly rescued his soul and teamed up with the queen's legitimate son to seize power and help him ascend the throne as emperor. Qin Shen, as a man, worshiped the left prime minister and set up a school for women against all opinions, breaking the shackles of the secular world. The emperor knew that he was not human but still trusted him. After the country gradually stabilized, Qingzhi took off his disguise and set up a demon manager to balance the world of humans and demons. His sister spent the rest of his life with the crippled queen who had recovered his memory, and finally made "the capable live" the norm in the world.
