Eleven kilometers deep in the sea, in the dark abyss of the Mariana Trench, lies the earth's oldest secret - the giant unknown skeleton accidentally captured by the deep-sea probe. The bone pattern carries the weird spiral of non-carbon-based organisms, as if it is a fragment left by an ancient god. Chen Meng, a female college student at Qingcheng University of Paleontology, was originally an ordinary researcher immersed in fossils and specimens, but she was entangled in a recurring strange dream: in the dark blue seawater, she could always see a pair of giant eyes covered with phosphorescent patterns, and a low-frequency hum that did not belong to human language echoed in her ears. The end of the dream was the complete outline of the deep-sea skeleton. When the real-life scientific expedition team released a blurry image of the skeleton, which was exactly the same as what she saw in her dream, Chen Meng realized that this dream was not an illusion, but a call that spanned tens of millions of years. With her paleontological acumen and persistence in the unknown, she began to pursue the truth behind the bones - is there another civilization in the deepest part of the ocean? Is this ancient remains related to the legendary sleeping deep sea god? A deep-sea adventure intertwined with scientific exploration, mythological secrets and personal destiny begins here.
