The Shen family, the richest man in the south of the Yangtze River, was overturned overnight. Shen Qingyi, the legitimate daughter, assumed the pseudonym "Xiaoqi" and entered the regent's palace as the lowest maidservant. Everyone thought she was an ant that could be manipulated, but they didn't know that she had ironclad evidence in her sleeves and a chess game in her heart. From the laundry room to the court, she took every step and tore open the fig leaf of the powerful with her own hands. But the cold-faced and iron-blooded regent pushed her against the wall in front of everyone, and said in a low voice: "You have calculated everything in the world, but you have failed to calculate - I cannot live without you."
