Shen Zhiyi has been the daughter of the Shen family for twenty-three years, but at the birthday party, Shen Mingzhu exposed her identity as a "fake daughter" with a fake DNA report. She was rejected by her adoptive parents and abandoned by her fiancé Gu Jingshen. In a desperate situation, the power of the "crow's mouth" in her body awakened, and a book of words and spirits that identified her master appeared in her palm. She also discovered that she was pregnant with Gu Jingshen's child. Canary, who was once in captivity, has since become a spiritual master, vowing to recover all debts owed. She relied on the power of words and spirits to avoid disasters and find the truth, gave birth to her son Shen Nian alone, and returned from hibernation for three years as the designer Nina. Gu Jingshen suffered backlash for betraying the Lord of Words and Spirits, and his words would bring disaster, so he pursued his wife to atone for his sins; the truth about Shen Mingzhu's fake daughter and the conspiracy of changing babies for twenty-three years gradually came to light. She uses the spirit of speech as a blade to judge all lies and betrayals, protect her young son, and avenge her grievances. The canary that breaks free from the cage finally spreads her wings and soars, completing the inheritance of the power of the spirit of speech while protecting her, and becomes her own light.
