The "Trial Ground" is an infinite loop space that is forced to involve participants. Participants are randomly thrown into different copies (apocalyptic ruins, strange campuses, future cities, mythical illusions, etc.). If you complete the task, you can gain points to strengthen your abilities. If you fail, you will be swallowed by the space. And these eight young people are the "bug-level team" that causes the system the most headaches in the trial field.
