Shen Luan, the Empress of Great Zhou, and Su Jin, the Noble Consort, were mortal enemies in their previous lives. After both met their deaths in the cold palace, they unexpectedly transmigrated into the 1970s as two sisters-in-law who were treated as expendable scapegoats and bullied mercilessly. One was extorted by hooligans and neglected by her husband, while the other was drained financially by her birth family and schemed against by her husband's family. Former enemies become allies in this life. Putting aside their past grudges, the two join forces to turn their situations around, outsmart scoundrels, tear into their appalling relatives, and break away from their two cold-hearted husbands. Starting out in a dilapidated, leaky house at the end of the village, they seize the opportunities of the times with ancient medicinal cuisine recipes and business acumen, rising all the way to establish factories and open shops, ultimately becoming two formidable women in the business world.
