Wan'er entered the palace at the age of seven, and finally saved enough money to find a good job for herself. Unexpectedly, on the first day, she heard that the Qiang people had invaded Beijing. She only felt pain in her heart, her money was gone, her errands were gone, and when she was running for her life, she accidentally picked up a man who turned out to be the emperor. He promised Wan'er that he would protect her for the rest of her life as long as she protected him for a while.
