Cai Wu was originally an ordinary college student, but she died in an accident. Just as her consciousness dissipated, a mysterious voice issued an invitation to her: to become a taskmaster of the "system", traveling through thousands of novel worlds, making up for others' regrets or correcting their fate. In order to get a chance to be reborn, Cai Wu accepted the contract and began her journey of fast travel.
In each world, Cai Wu must face different challenges: in the ancient court, she needs to help the wronged queen clear her grievances; in the modern city, she must regain everything she deserves for the illegitimate daughter who was abandoned by her family; in the interstellar age, she must prevent a war that may lead to the destruction of mankind. With the completion of the task, Cai Wu gradually accumulated various skills and knowledge, and gradually recovered her own emotions and humanity from an emotionally indifferent "tool person".
However, as the mission deepened, Cai Wu discovered that the "system" was not as simple as it seemed, and it seemed to hide some kind of secret. At the same time, her actions in various worlds also attracted the attention of certain beings, who began to interfere with her missions and even threatened her life. Cai Wu must complete the system's tasks while uncovering the truth about the "system" and the real cause of her death.
Eventually, Cai Wu discovered that the "system" was created by a powerful being called the "Destiny Weaver" in order to collect the energy of various worlds to maintain its own existence. The reason why Cai Wu was chosen is that her soul has a special ability and can change the established destiny. Facing this final BOSS, Cai Wu must use the skills and knowledge she has learned in various worlds, as well as the allies she has made, to launch a final showdown with him that affects the fate of thousands of worlds.
Concept: Each world has its own specific operating rules and physical laws
