He is Lin Hai, recognized as a "good-for-nothing" in the fishing village. He always returns empty-handed when he goes to sea, and is looked down upon. Even his ancestral fishing rod can barely pay off his debts. During a storm, he was swallowed by a huge wave while trying to save others. When he was about to die, he merged with a mysterious deep-sea creature and accidentally awakened the power of "deep-sea empathy"!
From then on, the ocean no longer had any secrets in his eyes. Sense fish, communicate with living beings, and understand currents... His "fishing IQ" crushes modern technology! With a worn-out ancestral rod, he went from being ridiculed as a good-for-nothing to becoming a "son of the sea" who has conquered the world's professional arenas, with fame and fortune at his fingertips.
However, the stronger his ability, the more he can "hear" the wails and mysterious calls in the depths of the ocean. Legendary fishing grounds, unknown secrets, ancient ruins... He was forced into a whirlpool that went far beyond competition. A secret organization that pursues the power of the ancient ocean, the "Eye of the Deep Sea," focuses on him, and strange biological violent events occur in the global sea!
When the fishing rod was no longer pointing to the fish, but the truth and disaster related to the life and death of the ocean, Lin Hai discovered that the feedback from supernatural powers had a heavy price. He must risk everything and go deep into the abyss of the human forbidden zone to calm the rage and protect the blue that gives him strength but also scars him. What awaits him there will be the true appearance of the ocean, and an ultimate choice that subverts cognition...
