In order to survive, Shen Weiwan, the daughter of the guilty minister, pretended to be an idiot in the harem, but was framed and thrown into the cold palace, her life hanging by a thread. In a desperate situation, she used her astonishing wisdom to successfully attract the attention of the mysterious imperial master Gu Qingyan who lived in seclusion here, and worshiped him as her master. From then on, the Cold Palace became her place of practice, and the Imperial Master became her strongest support. Under the secret guidance of the emperor's master, Shen Weiwan learned the tricks of strategy, people's hearts, poison and chess, starting from the cold palace, and returned to the center of power step by step. During the day, she was a foolish and talented person who was bullied by others, but at night, she was the smartest disciple under the Imperial Master. She used the "Dragon Slaying Technique" taught by her master to create a bloody storm in the harem. She used the trick to kill people with borrowed knives, and counterattacked all the way from the lowest level of talent, and finally overthrew her old enemy, rehabilitated the family, and gained power in the government. The highlight is that the heroine is not reborn or has a golden finger. All her strength comes from the master's teachings and her own tenacity and wisdom, showing the ultimate "nurturing system" palace fighting pleasure and the emotional tension of the taboo between master and apprentice.
