Ten years ago, she was imprisoned by a dark killer organization, codenamed Seventy-Nine. Ten years later, she was rescued by the spy leader Mo Qingchen, named Li Wuyou, and started a split "double" life. During the day, she is a quiet and introverted talented woman with a smile as bright as a flower, playing the piano and reciting poems; at night, she is a secret agent who kills decisively, holding a sword in her hand to protect the light.
Mo Qingchen was ten years older than her. He gave her a new life, taught her how to control her power, and planted an unspeakable feeling in her heart. However, a storm suddenly arises, and the talented but thoughtful noble son Shen Zimo intervenes forcefully, using Mo Qingchen's safety and her past as a bargaining chip to force her to make a choice. At the same time, murderous intentions are hidden in the Jiangnan water town, Cao gangs are entangled, and conspiracies are surging.
In the whirlpool of friendship and safety, how will Li Wuyou protect the hard-won peace? When Mo Qingchen is poisoned and her life or death is uncertain, where will she go? And what changes will Bai Huaian, the goddess doctor who is as straightforward and free as the breeze in the mountain, and Gu Yan, the gentle but elegant owner of the study who has a secret mission, bring to their destiny?
This is a Machiavellian love and hatred about redemption and growth, protection and betrayal. See how the two-faced beauty sticks to her true heart amidst the ups and downs, joins hands with the one she loves, breaks through the fog, and finally finds inner peace and her true self.
