Ye Huang, a top modern national security agent, dies in the line of duty and transmigrates into ancient times, becoming Shen Qiwu, a concubine-born daughter framed by her legitimate elder sister, poisoned into silence, and abandoned in the Cold Palace. The original Shen Qiwu dies with her grievances unresolved, but reborn from the ashes, Ye Huang uses her agent skills and modern knowledge to solve bizarre cases, expose internal traitors, and cure poison to save a prince, throwing the inner palace into turmoil. She has no interest in fighting over a man's affections; she is focused on building a powerful nation. She improves military weapons, heads south to control floods, and strengthens the country's foundations, sweeping through the court with her abilities. The calculating emperor goes from testing her to falling for her, protecting her with all his might. From a mute consort abandoned in the Cold Palace to a pillar of Great Zhou, she rises to the summit as a woman and reigns over the world!
