Above the Clouds, I Turned the World Upside Down

Others traveled through time with golden fingers, but Cheng Ji picked up a golden palm. Start by breaking the backend of the world, and fix the bugs in the world along the way, using unorthodox methods to fix serious errors - or, if it's broken, just restart it completely. A high-authority "ordinary person" who has a bit of a petty-citizen mentality and likes to take shortcuts. A system that is familiar with the underlying logic of the system and talks nonsense. A foodie plug-in that can crack everything and be used as a conceptual weapon. Watch three scourges come together to torment the world. It's a clever and entertaining story, with a single female protagonist and a grand world view.
