In the depths of the ocean, thousands of sea races are nurtured in different sea areas. Beneath the abyss lies the mysterious Eye of the Siren, which continuously releases spiritual veins to nourish all things and create various underwater groups. When the Sea Tribe was young, they had the characteristics of their original animal form. When they reached adulthood, they could freely switch between their human form and their true form. Each tribe also had unique innate abilities.
Luoning, who was born in the Luo tribe, has been yearning for it since he was a child and determined to become a maritime investigator. Many years later, she entered Hanhai Academy, the highest school in Yanhai, where she met Jingwen, a member of the whale clan, and a group of like-minded partners. They traveled together through rivers, lakes and seas, visited ancient ruins and deep trenches, and explored strange phenomena that kept appearing everywhere.
They slowly uncovered the secrets left over from ancient times and explored the truth behind the pollution outbreak. They learned that the disaster had not completely dissipated, and that the hidden dirty power was still waiting for an opportunity to come back.
When a new round of pollution crisis quietly spreads, Luoning and his partners are no longer just explorers. The teenagers relied on their own talents and abilities to work hand in hand and follow the clues of their spiritual veins to find the source of the pollution. They shoulder the mission left by the ancestors of the sea tribe, fight against the darkness of the abyss with courage, and vow to protect the blue sea on which they depend for survival.
