Not far from the 20th-floor's Dungeon crystal vicinity, I and the twin standing and waiting silently, while having a light conversation.
If you guys wondering why I didn't proceed directly to teleport to the boss room, get the thing done with the boss and proceed to the 21st floor, it's because I can't do it willfully like that.
There's some restriction and regulation here on the 20th floor if we want to challenge the Boss.
Since the boss guarding this floor isn't that strong, a lot of adventurer party has a great interest to challenge it.
Because of this, the Adventurer Guild and the City Lord decided to create a regulation about challenging the boss on the 20th floor.
Every party who wants to challenge the boss again needed to register, then lined up to challenge the boss room.
