Deep-sea explorer Chen Mo accidentally fell into an abyss of 10,000 meters during a mission to explore Europa, and was parasitized by the last consciousness of an extinct civilization. Since then, he has gained the strange ability to resonate with the thoughts of marine creatures - he can hear the thoughts of fish, feel the pulsation of ocean currents, and even establish a spiritual link with the giant beasts of the deep sea.
But this ability is not a gift. His body began to slowly become transparent, and the parasitic consciousness was passing through him, trying to awaken the ancient existence sleeping in the deep sea of the earth. When collective abnormalities occurred in marine life around the world, and when unexplainable whispers came from the deep sea, Chen Mo found that he had become a bridge between the two worlds - and the last line of defense for mankind.
