Deep within the treasure hunting space, there's an endless ocean where countless ferocious sea creatures reside. According to the Universal Alliance's investigation, the likelihood of powerful life forms emerging is higher in oceanic environments.
At the center of this ocean stands a massive ocean fortress, where millions of treasure hunters have gathered. Thanks to a powerful sonar weapon, this city has managed to survive amidst a sea teeming with ferocious beasts.
"Crackle!" On the coast at the edge of the city, a fire is blazing as several youths sit around grilling the meat of some unknown sea creature. Beside them lies the corpse of a ferocious beast over 800 meters long.
"Brother, if it weren't for you this time, we would've perished in this sea."
