Shen Weiwan, a scholarly concubine, was forced to enter the palace to protect her biological mother. She was a lowly and talented person for the first time. In the palace, the queen and the noble concubine were divided into rival factions. The concubines from all sides plotted against each other. The emperor Xiao Jingyuan was suspicious and cool. The harem has always been just a chess field for the previous dynasty to weigh. She restrained her edge and stayed dormant, pretending to rely on the queen to survive, secretly gathering her confidants and retaining leverage, and using her talent and wisdom to win the emperor's affection. After rising to the concubine position, she became independent and became close friends with Su Jieyu who was in trouble. She was caught in a pregnancy disaster and was repeatedly framed, and all her former soft-heartedness was wiped away. She used her power to dismantle the military power of Concubine Hua's relatives, and used years of criminal evidence to counter the Queen's conspiracy to frame the family. After the storm settled and the throne was vacant, Shen Weiwan saw through the ruthlessness of the emperor and the vanity of the palace. She refused the phoenix seal and avoided disputes. She lived in a side hall with her young son, under the red wall and glazed tiles, and kept a corner of peace for the rest of her life.
