The escape from one prison zone to another was relatively smooth, but when the group returned to the headquarters above the ground, the difficulty increased.
No matter what, the underground dungeon was a secret building, so there were not too many guards so as not to attract people's suspicion.
However, the headquarters above the ground was a legitimate building, so there could be as many guards as possible.
Although the security measures were actually loose and not as good as the underground dungeon, with so many guards, various problems began to emerge.
The prisoners who successfully left the underground dungeon were mostly members of the world union who did something wrong and were punished.
However, very little of these people actually betrayed the world union, so the rest were actually still loyal, but they were naughty.
