At the age of eight, Shen Qingyue, the legitimate daughter of the Prince of Zhenbei's estate, hid in the rockery on a snowy night and witnessed her mother, Madam Liu, being framed, beaten, and brutally murdered by Cui Jin, Cui Bo, and others. Clutching her mother's auspicious cloud silver bell, she fled barefoot and, when on the verge of death, was saved by the young Xiao Zheng, dropping the moon-engraved silver bell. Twelve years later, Shen Qingyue returned to the prince's estate disguised as a frail and sickly woman, using her wisdom and her enemies' greed to take revenge. As an official of the City Patrol Bureau who had spent years tracing the old case with the bell, Xiao Zheng recognized Shen Qingyue and secretly assisted her, gathering evidence of Cui Bo's treason. With the unjust case vindicated and the culprits brought to justice, Shen Qingyue returned to the snow to reconcile with her childhood trauma, let go of her deep blood feud, and traveled far to Jiangnan with Xiao Zheng to practice medicine. The bitter snow finally cleared, granting them a peaceful remainder of their lives!
