Su Tang was supposed to be hanged after the defeat like other members of the royal family, but there were so many princesses and princes that no one remembered her existence. In addition, the personal maid was deliberately dressed up, so she was captured as an ordinary maid and sent to the enemy country. Because of her outstanding appearance, she was sent to the Red Mansion to be cultivated as a vulgar creature for people to play with. However, Su Tang was not the kind of person who just recognizes people and slaughters them. During her years in the palace, she had long learned to rely on others rather than relying on herself. By chance, she overheard the conversation between the Red Mansion mother and other people, and learned that one of them had the daughter of the current Prime Minister who had been left behind. After some planning, she successfully applied this identity to herself, and thus left the Red Mansion smoothly, and started her plan to make a success of it step by step.
