Hai Cheng, a young marine ecology researcher, witnessed the strange bleaching of his beloved coral reefs and the abnormal behavior of marine life. He unexpectedly discovered that the culprit was "entropy algae", a strange blue algae that grows wildly as seawater acidifies. The "restless breath" it releases is quietly changing the rhythm of life in the ocean. With the worried narration of veteran fisherman Zhao Haisheng, the keen insight of returned algae expert Lin Wan, and the persistent companionship of his assistant Lu Yu, Haicheng embarked on a journey to find a way to fight. From offshore fishing grounds to deep trenches, they wrestled with the invisible force of entropy, and finally lit up the glimmer of light to observe and protect the mysteries of marine life at the edge of the Mariana abyss. This is a journey of redemption that finds balance between the rhythm of life and the whispers of chaos.
