I've Started Over.

When Yun Shu wakes up, she has gone from the modern world to an unknown cybernetic civilization. As soon as she arrives, she is unlucky enough to be sent to a mine. She has to work grueling hours, eats nothing but black bread, and has to fight for a spot on a broken wooden plank to sleep. If she dies, no one will care. In this world, the rulers of the corporation known as "God" control everything with armed robots and extraordinary knightly orders. Under a system of citizenship tiers, ordinary people do not even have the right to live. The Jiuyiao Group, the Church of Dawn, and the Daylight Organization all claim to be the light, yet each goes against it. At first, all she wants is to stay alive. But eventually, she realizes that the only way to survive is to overthrow this twisted world. So she begins in this brutal mine, taking the codename "Tomorrow." Step by step, she becomes the resistance's supreme leader, while the Jiuyiao Group gains a high-ranking double agent. From then on, mechanical life has a true master. If this world has no light, then I will become its new light. The faithful: You are the One and the Many, and the world crowns you. Only later do people learn that no new god ever descended. From beginning to end, it was simply the return of the former savior. This is the story of a retired savior saving the world once more. It is also a feel-good power fantasy with a strong female lead, my take on cyberpunk, with a mountain of original worldbuilding. Theme: Light will come in the end.
