Jing Ru used to sell houses in the Crimson Sky Kingdom, one of the Ten Great Dynasties. On Earth, she would be known as a realtor.
When Duan Ling Tian was in the Crimson Sky Kingdom, he had bought a house from her. At that time, he had taught a disciple in the Duan clan a lesson because of her. He was worried that the disciple might take revenge on her so he hired her to be the steward and housekeeper of his house. Moreover, she had a good character as well. From then on, she had been responsible for looking after the house and Duan Ling Tian's mother, Li Rou's daily living. After Duan Ling Tian left and became famous, she continued serving his mother.
