The day Su Wan was selected by the quick travel system, she thought she was the chosen one. It wasn't until the third world that the system suddenly told her that the experiment was over and ready to be wiped out. She discovered that her mission was not to change the tragedy at all, but to provide nourishment to the system - the more miserable each world was, the more energy the system harvested. Moments before her death, a man named Gu Shen rescued her and told her the truth: the system itself is the biggest villain, and they are trapped in a loop and can never get out. Su Wan smiled. If you want to be a villain, then be the most ruthless one. She started from within the system, dismantling the world one by one, changing the system's carefully designed 'tragedy script' into a comedy, so that the cannon fodder in each world could turn around. The perfect host sent by the system urgently hunted her down, so she took advantage of the loopholes in the system's rules to fight back. Until she discovered that even 'Zero', the system administrator, was waiting for her to overthrow this cage.
