The nine-year-old concubine Mu Qingcheng was tortured in the countryside. In a disaster caused by the housekeeper of the Hou Mansion, she was forced to kill herself to protect herself, but she lost her mother and sister. After returning to the Hou Mansion alone, she saw through the warmth and coldness of human nature, and determined to use her wisdom and beauty to climb up. Through observation and planning, she identified the weak spot of the mistress Shen Li - her secretly seriously ill "nephew", and entered the center of the power whirlpool as a substitute. Finally, she revealed the shocking secret of her identity, took advantage of the opportunity to overthrow the mistress, and climbed to the top of the power of the Hou Mansion.
