In the gray-blue ocean observatory, sonar engineer Su Yan captured mysterious voiceprint signals for thirty-seven consecutive nights. One foggy night, he rescued an unconscious woman from the rolling waves - she was as pale as porcelain, with faintly visible scales on her neck, but under the ultraviolet light in the medical room, she showed an inhuman fluorescence. She calls herself "tide", but she is unfamiliar with modern languages. Instead, she uses rusty ship nails, broken glass and shells to spell out obscure poems on the table.
At the same time, in the basement of the observatory, an ancient "mermaid specimen" soaked in formalin was quietly leaking light blue liquid. Oceanographer Lin Yuan discovered that tide's teardrop crystals have deep-sea superconducting properties, and her DNA actually matched the sightings recorded on the World War II sunken ship "Green Stork Maru" seventy years ago.
In 1943, young sailor Ye Han met the injured mermaid "Ling" in the wreckage of a battleship. They cast rings from shell shells and fell in love in the blind spot of sonar detection until military doctor Sato's scalpel cut through the tranquility. In order to preserve Ye Han's genetic samples, Ling volunteered to become a specimen, while Ye Han sank into the trench and used his life to light up the last navigation light.
Time and space overlap here. The cloned body of modern tide is gradually becoming transparent due to the awakening of cellular memory. The red tide outlines a human-shaped hole in the sea. The telegraph code from the Second World War suddenly appears on the receiver of the observation station. Su Yan must dive into the seventh level of the sea where even the sun cannot reach, and find the ancient mermaid city made of sunken ship parts among the sulfur smoke pillars from the hot springs.
When the oxygen in the deep-sea hyperbaric chamber is about to run out, and when the moonlight is divided into broken silver coins by the sea water, the love of the two eras will complete the final resonance in the eternal night layer - let Xi return to the deep-sea tribe to complete the migration mission, or will she be imprisoned in a cage on the shore forever using human technology? And the truth that sank eighty years ago is emerging as the layers of pearls peel off...
Intention: The love in the deep sea is like static pressure for eternity, and the reincarnation of clones cannot match the momentary sincerity of human beings.
