Song Jin traveled into a smoke game produced by Bug System, but in a real simulated world where death is real and injuries will hurt, only by "clearing the level" can one return to the original world. There are twenty levels in total, and the lowest level is Level c, the highest is level ssssss, there will be additional rewards or penalties for triggering the secret system. Song Jin accidentally traveled inside in the bug game, because he was the first experimental subject inside, and God B arranged a system for him to protect him and help him complete the task.
