Small Fishing Boat Followed A Massive School Of Fish Into Heavy Fog. When The Mist Finally Cleared, They Realized Their Grave Mistake. 

Moving quickly together on the damp deck, the two friends dropped the heavy ropes and nets into the freezing water. They expected to quickly scoop up the dense school of fish and finally head home. But the catch was proving to be incredibly stubborn. No matter how much Min-ho pushed the engine, the green dot on the screen stayed just out of reach. 

On the monitor, the bright cluster kept accelerating, driving deeper into the trench in a remarkably straight line. “They are running fast!” Jun called out from the cabin window, adjusting the brightness on the screen. “The current down there must be carrying them. They are sprinting deep.”

Min-ho frowned, forcing more power into the old diesel engine. The boat groaned as it struggled to keep pace with the fast-moving green dot. The relentless speed of the school below was beginning to frustrate them as they watched the bubbling water behind the stern. The goldmine was slowly slipping away, dragging the two friends further and further into the mist.
