Cui Mingyuan, the second concubine of the Yongning Marquis Mansion, could not recite a thousand-character essay at the age of three, and ran away from three gentlemen at the age of five. The whole family said that this child was a dead wood. Shen Henghua smiled while holding the tea cup. Dead wood? She had seen how the top disciples of the Shen family were raised. That day, she pressed Cui Mingyuan's hand on the poisonous scorpion: "Does it hurt? Remember, next time someone hurts you, you have to make it hurt more." When the nanny sent by her aunt-in-law deducted the money, Shen Henghua did not make a fuss and only sent a bowl of "Lung Nourishing Soup" to her mistress. Three days later, the nanny knelt down and begged her to detoxify. When someone in the clan school laughed at Mingyuan for being a concubine, Shen Henghua taught him: "My father is a marquis, who is your father?" Three years later, Cui Mingyuan entered the Imperial College as a concubine. Those who had looked down on him found that this young man was surrounded by a group of loyal guards, all of whom were tied up by Shen Henghua with money and kindness. But no one knows that this female gentleman with extraordinary skills was once the last orphaned daughter of the criminal Shen family. And her secret is being watched by one person - the youngest criminal doctor in the capital, Gu Yanzhi. What he was investigating was the old case of the Shen family.
