Su Qingwu, an orphan girl who was stigmatized as the "Lone Star of Heavenly Evil", was adopted as an adopted daughter by the Yong'an Marquis Mansion in the capital city in the name of "bringing happiness" and "stopping evil spirits", and stepped into the treacherous deep mansion. She faced the hypocritical stepmother, the arrogant sister-in-law, the insidious concubine, and the cold eyes and calculations of the entire Hou family. Su Qingwu relied on the poison-healing skills she learned in Taoism, her ability to observe people's words, and her resourcefulness far beyond ordinary people, to expose the conspiracy step by step, punish the evildoers, and trample those who despised her under her feet. She gradually grew from a chess piece who was bullied by others to a being that no one dared to mess with in the Hou Mansion. In the process, she met Xiao Changyuan, the eldest son of Prince Jing's palace who was also a "adopted son" but actually hid a shocking secret. The two tested each other, cooperated together, and fell in love with each other. In the end, they worked together to overthrow the court and uncover the mystery of their respective life experiences. Su Qingwu also counterattacked from a notorious foster daughter of the Hou family to a powerful first-class mistress in the world.
