After all, despite being sea slaves, their Captain had left them with all their dungeon rewards, only taking the dungeon passes and mana crystals. They had never expected this; they had thought he would act differently. They knew they had no power to resist him, as he was the master of their slave contract, and especially given his strength.
So, even if they couldn't make it into the crew's core raid group, they knew they had to show they were worthy of such a reward.
After all, wouldn't the Captain change his mind and take all the dungeon rewards for himself if their strength was so weak that they could contribute nothing in the future?

Outside the Sunken Coral Cavern Dungeon,
A ship appeared on the horizon.
A man with warm brown skin, dressed in blue armour with bluish shades on specific parts inscribed with mysterious markings, stood at the bow, the front part of the ship, staring at a brass compass in his hand.
