Twenty-three-year-old programmer Jiang Zhuo died suddenly while working overtime, and his consciousness was dragged into the global death game "Return to Zero." Random teleportation, clearing the dungeon, and real-life death upon failure—she was thrown into the "Secret Room Butcher" hell round at the beginning. The teammates were fighting among themselves, and the Butcher's power was cut off. She hid in the ventilation duct and waited to die. At the moment of death, the system pops up a BUG option: [Do you want to return the product? She clicked "Yes", the screen was reset, the memory was retained, and the reward was doubled. From then on, while others worked hard to clear the level, she specialized in returning. Is this level too bad? Retreat! The equipment is not strong enough? Retreat! Are your teammates too stupid to hold you back? Back, back, back! She treats the system as a cash machine and the dungeon as a save point, swiping rare skills again and again. But when she used "Pain Shield", black market intelligence showed that someone had used this trick ten years ago. The mother's name is clearly listed.
