Shen Mingzhuo guarded the ancestral lamp for the Shen family for ten years, exhausting her lifespan to ward off disasters for her clansmen. Yet the clansmen stripped away the lamp-guardian's title and gave it to her elder sister, Shen Mingzhu, and her fiancé, Song Yan, also favored the Shen family. When the ten-year term expired, Shen Mingzhuo resolved to leave. The ancestral lamp failed, and to light it, the Shen family destroyed her mother's life-protecting lamp wick and forcefully took her heart's blood. Secretly, Shen Mingzhuo removed the lamp contract, letting disaster backfire on everyone. Lamp-master Xie Changyan arrived, exposing the past truth: the one who should have guarded the lamp was aunt Madam Zhou, who colluded with clan elders to force Mingzhuo and her mother to suffer in her place. Song Yan repented and begged for reconciliation, but was rejected. Shen Mingzhuo rescued Xiaoman, refused to be a sacrificed lamp any longer, and followed Xie Changyan to rescue those persecuted by lamp contracts.
