Mingyue Training Institute

Chen Mingyue was exploited by her uncle, Chen Boyuan, and imprisoned along with over a dozen innocent girls in the Chen family's reformatory, suffering brutal abuse and starvation from wicked servants like Matron Gui, serving as a tool for him to curry favor with the powerful. After resisting the influential Lord Zhou, she was forced to take drugs by Chen Boyuan and discarded on the streets. Transmigrating back to the day she was brought to the Chen residence, Chen Mingyue vowed to take revenge and rescue all the victimized girls. To lower Chen Boyuan's guard, she disguised herself as a frail, obedient orphan to enter the Chen household. She cunningly sowed discord between Matron Gui—who had abused her—and Chen Boyuan, tricking him into punishing the matron. Meanwhile, she secretly spread rumors of the Chen family's cruelty toward young girls to set the stage for their downfall. One night, wearing a human-skin mask, she infiltrated Chen Boyuan's study for evidence. She encountered a maid named Chunxing, who was being hunted by the steward for stealing to treat her mother, and saved her by posing as a ghost to scare off the pursuers, successfully winning Chunxing over as an outside informant. Afterward, she had Chunxing use a silver hairpin left by her mother to contact Mr. Six-Fingers, who had been secretly gathering evidence against the Chen family for years, gradually building a network of support to seize critical evidence, bring down the villains, and save the girls.
