The sea level ruthlessly swallowed up the old prosperity, and the underwater city "Atlantis II" became the new home of mankind. Ye Nan, a genius graduate student in deep-sea exploration at the Ocean University of China, drove the "Sea Dragon King" submersible, which he had worked hard on, deep into the dark abyss. His target is the ruins of the Forbidden City that have sunk in the dust of history. A seemingly ordinary detection mission took a turn because of a Ming Dynasty shipwreck porcelain - the strange and tiny life sealed in it could actually purify deadly nuclear wastewater. Ye Nan is faced with a choice: should he rush to develop this "savior" power, or should he stick to his belief of "zero disturbance of marine ecology"? Under the guidance of his mentor Su Qinglan, the assistance of his assistant Lin Xiaoya, and the witness of the old captain Balto Iron Anchor, Ye Nan will use superb technology, firm principles, and awe of marine civilization to guard the secrets of Deep Blue amidst the undercurrents, and ultimately promote the birth of the Convention on the Protection and Utilization of Deep Sea Civilization, proving that the true value of deep sea exploration lies in connecting the past and the future, and protecting the fragile balance of civilization and ecology.
