An unprecedented flood submerged the surface of the earth, and humans were forced to migrate to the deep sea and build the colonial city of "Atlantis". However, this last bastion of mankind has undergone tremendous changes! Ecological engineer Karen Deep Blue thought he was just a mechanic maintaining oxygen and energy, but he witnessed the core system being bizarrely destroyed, and unknown energy-devouring creatures emerged in the deep sea! The shadow of doomsday looms, and the colonial city is in danger. Karen discovered that this was not only a natural disaster, but also a man-made disaster! The remaining forces on the ground covet the core data of the "Ground Reconstruction Plan" in the colonial city and want to take it for themselves. What's worse is that those unknown creatures called "monsters" can actually communicate with humans simply, and their appearance is closely related to human pollution! Faced with internal and external troubles, Karen must race against time to repair the equipment and fight against the masterminds behind the scenes. At the same time, she is caught in a moral dilemma: Should she eliminate these "monsters" born of humans in order to survive, or should she seek a way to coexist, which may lead to catastrophe? The mysterious "Core of Deep Sea Ruins" he holds will be mankind's only hope and the key to overturning the old order and reshaping the future! A deep-sea epic about survival, technology, morality and evolution begins here!
