My name is Yu Deshui. On the day I was laid off, I got a call from the other side of the world: my grandfather had left me an Alaskan fishing ground, along with a staggering $780,000 in debt! I have 90 days to pay it off, or I'll pay with my life? Local financial magnates are secretly blocking my access to the market, hoping to leave me with nowhere to turn. Just as I nearly drown in the icy sea, an ancestral fish-eye stone merges with my body and activates the [Blue Sea Ranch] System! From then on, my eyes can see through the entire polar sea: where the king crabs are wintering, where century-old premium abalone are hidden. A holographic star chart lays it all out! The entire Hong Kong market has blacklisted me? I airlift my catch straight to Tokyo, shattering the Japanese cuisine world's accepted wisdom and making a sushi master of the highest caliber drop to his knees! Foreigners laugh at my battered boat and shabby nets? I set up a giant iron wok and stir-fry king crab with scallions and ginger, filling all of Hong Kong with its irresistible aroma. Countless heiresses and Michelin-starred chefs line up for three years just to get a bowl of my crab roe noodles! Starting with one broken boat, I take over the financial magnates' businesses and build a polar ecological farm. When the legendary [Nine Delicacies of the Blue Sea] appear, I, Yu Deshui, will be the one and only king of these deep waters!
