When she was fifteen years old, her legitimate daughter Shen Yurong watched her mother cough up blood and die, and heard her concubine's whisper before her death. A silver hairpin with plum blossoms and half a page of blood-stained prescriptions revealed the poisonous plan in the deep house of the Hou Mansion. She was sent to the palace as a pawn, but the concubine married the general she had a crush on. From being a talented person to being a queen, from listening to the government behind the curtain to returning the government, for eighteen years, all the way to the palace, the nine jade steps were stained with blood. Double-dealing, sisters' estrangement, the mystery of their life experience, the power game... When she finally reached the top of power, she saw through the cruelest truth: the poor are like grass in front of wealth, the rich are like ants in front of power, and all power will eventually be annihilated in the long river of time. This is an epic about revenge, growth and letting go. It is also a tragic song about a woman regaining her destiny in an era of cannibalism.
