In the deep palace of the Forbidden City, the humiliation of kneeling down to beg the imperial doctor on a snowy night, and the unforgettable pain of losing her son, made the once-famous concubine Wei Yanwan completely wake up - in this cannibal harem, kindness is the original sin, and tolerance will only lead to more severe bullying.
Forming an alliance with the loyal eunuch Jinzhong, Wei Yanwan embarked on a carefully planned revenge. On the surface, he is respectful and humble, but secretly he is careful at every step. She used retreat to advance, and used softness to overcome strength. Under the seemingly impregnable position of Queen Ruyi, she quietly opened the cracks in the emperor's trust.
From the amulet suspicions to the prince's poisoning, from the harem rumors to the previous turmoil, a series of seemingly coincidental "accidents" are actually closely linked and carefully planned. Wei Yanwan and Jin Zhong teamed up to use their tactics to the extreme, and staged a thrilling counter-murder drama in the tumultuous harem struggle.
However, Concubine Yu Hailan snoops in the dark, Queen Ruyi becomes increasingly doubtful, Emperor Qianlong is suspicious and fickle... All forces compete in this splendid cage. When the truth gradually emerges, what will be the outcome of this revenge?
This is a battle about power and survival, and it is also a test of human nature and choice. When the phoenix sings in the sky, who will be the final winner?
