During the Jing Dynasty, Shen Jinghong, a young martial artist, was bound by a mysterious prophecy since she was a child, saying that she would fall in love with a ruthless person and eventually die of love. She didn't believe in fate, and used her sword as a shield to kill all the unfaithful people in the world, living a fierce and lonely life. When she was sixteen years old, she was assassinated in the south of the Yangtze River, and was saved by Xiao Yunxi, a young man from an aristocratic family dressed in white. However, he rejected her when she confessed her love: "I can't bear this girl's infatuation." When they reunited ten years later, Xiao Yunxi was already the powerful official minister Lu Zhiyan. , He circled her trembling chin with a red pen: "I'll be the one to chase this time, okay?" Shen Jinghong struggled with resistance and wavering, but found out that there was a shocking secret behind his "unkindness" back then - Lu Zhiyan deliberately pushed her away to protect her from the prophesied curse. When fateful prophecies intertwined with real-life conspiracies, Shen Jinghong finally understood that the true destiny was never determined by God, but was held in his own hands. Not only does she want to kill all the unfaithful people in the world, but she also wants to capture the master of the palm who has been hiding his tenderness for half his life, and negotiate a two-way fight that is evenly matched in the whirlpool of power.
