On the eve of the glacier collapse, climatologist Shen Han saw the doomsday warning of the collapse of the thermohaline circulation, but was rebuked by his family and ridiculed by the world. He made a desperate move and spent his savings to transform an abandoned Antarctic exploration station into a deep-sea refuge called the Ark. Seven years after the ice cap swallowed the world, an out-of-control military nuclear submarine crashed into the dome. Shen Han rescued the only survivor from the wreckage, high-energy physicist Su Wantang. She carried the officer's suicide note: "The fire of humanity must leave behind a scientist."
The balance of the Ark was on the verge of collapse due to her intrusion. Shen Han's vigilance and Su Wantang's secret identity caused the two to test each other in the suffocating deep-sea island. From the life-and-death game of medical rescue to the fragile collaboration that jointly maintains the ecosystem, the two are forced to coexist amid low-temperature cultivation and energy crisis.
In a key experiment to transform a biological reactor, Su Wantang proposed a breakthrough plan based on his keen insight into deep-sea silicon-based materials. When the energy conversion rate of green algae and deep-water bacteria soared to 175.39%, Shen Han named the project "Symbiotic Arc" - this was not only the dawn of a technological breakthrough, but also the first glimmer of a break in the frozen relationship between the two.
However, the "KX-9 Extreme Illusion Plan" document that slipped from Su Wantang's sleeves, and Shen Han's fingertips hanging on the "Deep Purification and Isolation Procedure" when staring at the monitor screen, all indicate the underlying crisis under trust. On a metal island five hundred meters under the sea, can the last fire of mankind survive the long night amid suspicion and dependence? And outside the porthole window, the glacier is quietly cracking the first crack of spring...
