The Prince Regent's Concubines

Lin Yaofang tries to kill her, but she is saved by her older sister, who tells her that she can become the consort of the regent in this life if she can help her with three things: 1) take care of the jade house, 2) manage the business of the Lin family, and 3) inherit the crown prince's title. Lin Yaifang says that all of her family members will die in the next life, and she will be able to inherit their titles only after she becomes the regent. Lin Yaufang says that she has changed a lot in the past life, but that she will not change in the future.
