Shen Miaoyi, the righteous daughter of a great Confucian scholar from the south of the Yangtze River, married into the East Palace as the crown princess. However, she was deposed as a commoner after being framed by Queen Li for adultery and was thrown into the cold palace. Relying on the agricultural skills she learned since she was a child, she cultivated wasteland and improved rice seeds in the cold palace. Not only did she provide food and clothing for everyone in the cold palace, she also accumulated wealth through grain trade and conquered palace maids, secret guards, merchants and other forces. As her power grew, she gradually exposed the truth about the frame-up, fought back against the queen and her party members, and eventually became the queen mother to take control of the government, promote the country's agricultural development, and create a prosperous age.
