Two Quick-Traveling Sisters Earn Life Spans in Various Small Worlds

Jiang Xue and Jiang Yu are fraternal twin sisters. Not only do they look different, but their personalities are also very different. Jiang Yu is the older sister. She has superb medical skills and has studied many medicines. Whether they are good medicines that can cure diseases and save lives or poisons that can cause serious harm. Jiang Yu has a gentle personality, is smart and kind, but is not good at all. She is a sister-controller. What can my sister say? That's right, Jiang Xue is a younger sister, with a face that doesn't look like a mortal's, but she has been arrogant and domineering since she was a child, with big breasts and no brains. Her motto is: I would rather she let the world down than let the world let me down. Fortunately, the Jiang family is a famous family, with power and money, so no matter how much trouble Jiang Xue gets into outside, Jiang's father and Jiang's mother have the ability to deal with it. But suddenly one day, Jiang's father and Jiang's mother died in an accident, leaving behind a large inheritance and two phoenix jade pendants. Later, her sister Jiang Yu accidentally pricked her hand during an experiment, and the blood flowed on one of the phoenix jade pendants, activating the space. When Jiang Xue found out, she guessed that the end was coming, so that the space would appear, and maybe there would be super powers mentioned in the novel, so she also pricked her finger and activated another space. Indeed, after the space was activated, Jiang Xue had wood and water powers, while Jiang Yu had healing and ice powers, so they began to hoard supplies in large quantities. However, after they spent all their money, they did not wait for the doomsday, but the system "mistress." The mistress of the system uses the resurrection of Jiang's father and mother as bait, and requires the two Jiang sisters to complete tasks in various small worlds. Completing a task will reward 20 years of life...
