After the True Elites destroyed the camp around the Endless Ocean dungeon , many adventurer parties and small guilds had rushed in to try clear the dungeon.
However soon faced with reality they understood the difficulties of clearing the endless ocean. The easy mode required the party to survive for 20 hours , the normal mode 25 , and the nightmare mode to survive for 30 hours.
Even the easy mode clear had not been claimed yet , as the big first rate guilds had kept their pride and kept attempting the normal mode.
Well they had started with the nightmare mode , but soon giving up , they left for the normal mode , after repeated failures there , the demolition boys decided to put their pride aside and first claim the first clear of the easy mode.
