In the depths of the vast ocean, there is a legend about the Hades. The boat is said to possess a mystical power that corrupts people's hearts and sucks desires. It disappeared from history for 166 years, until recently, when a cruise ship full of deep-sea treasures quietly docked on Eggboy Island and announced that it would hold a grand auction. The explorers boarded the ship with curiosity and adventure, only to find that the atmosphere on board was unusually strange, and there was an indescribable sense of tension hidden under the ornate decorations and flashing lights, and they found these suspicious people when they boarded the ship.
The first is Captain Stoneheart, Souler, a figure of martial arts and mechanics, whose name appears prominently on the Hades' forbidden list, but who still recklessly boarded the ship. Captain Souler didn't seem interested in the ship's treasures, which made the explorers curious, and he risked being found on board the ship, but for what? Souler appears to be an energetic young captain with a distinctly pirate style, white hair and a red pirate hat, piercing eyes, and red and black armor, well-equipped for battle.
Immediately afterward, the explorers meet the first mate, a skilled seafarer. Popaul had a past connection with Sejan, but after Sejan's arrest, he did not take any rescue actions and was actively involved in the promotion of the auction. The explorers suspect that Popul's actions may have been carrying out some of Seran's plans, which may have something to do with the real purpose of the auction. Popol is a cute puppy wearing a navy hat and accessories, a dark hat with an anchor logo, and half-closed eyes.
Eventually, the eyes of the explorers are drawn to the mermaid singer Sairan, who is imprisoned in a giant water tank, her singing melodious and soft, but with an irresistible magic. Explorers wondered why such a powerful creature would be willing to be trapped instead of trying to escape. They begin to suspect that Sairan's appearance was not accidental, that she may have been arrested on purpose, and that her true purpose remains a mystery. Imprisoned in a water tank, Seran is still very conspicuous, her body is rich and dazzling, her hair is a flame-like orange-red, and her eyes are large and bright in color, dark blue, exuding a mysterious and dreamy temperament.
Explorers realize that these suspicious characters could be the key to unlocking the secrets of the Hades. They decided to dig deeper and look for clues from these characters. As the night progresses and the lights on the ship fade out, the explorers compile the information they gather into a questionnaire ready for the next day's challenges. They know that the truth behind this auction may be more complicated and dangerous than they imagined. But no matter how difficult the road ahead, they are ready to unravel the biggest mystery of the deep sea.
