Qianlong's Lonely Voyage: the Only Underwater Ark in the End of the World

I felt inspired after watching the perfect drama Doomsday Ship. Friends who like it can come and watch it. Lin Nan was promoted to Navy Lieutenant Colonel at the age of thirty and became the first mate of the only 40,000-ton super nuclear submarine in the country. The giant ship received a top-secret self-sustainability test mission: half of the ship's weapons and ammunition were cut off, and the huge ammunition compartment, mezzanine, and redundant compartments were all stocked with enough supplies, closed-loop ecological equipment, medical reserves, crop seeds, and a full set of maintenance spare parts for the entire ship's personnel to live for a whole year. In addition to the two hundred elite naval officers and soldiers on board, dozens of civilian scientific researchers in various fields were also dispatched to accompany the ship, with the goal of testing the feasibility of long-term deep-sea self-sustainability of large nuclear submarines. It has only been a few days since the giant ship sailed into the deep sea and began its submersible test. The entire radio frequency band was completely silent, all satellite links were interrupted, and there was no sound of human activity on the sea surface. After several careful surface explorations, everyone was horrified to discover that a global cataclysm had broken out in the outside world, terrestrial civilization had collapsed, cities had turned into lairs of aberrant monsters, and the entire world had completely entered the apocalypse. A 40,000-ton nuclear submarine loaded with materials, talents, and technology unexpectedly became an underwater Noah's Ark in the apocalypse. People inside the ship are in panic, and conflicts between weak factions, conservatives, and radical factions are constantly growing; above the sea, warlords are separatist, foreign warships are wandering, and giant mutant sea beasts are rampant. As the captain, Lin Nan stabilizes the order within the ship, drives this deep-sea hidden dragon to cruise around the world, gathers his compatriots, accumulates industrial wealth, and builds a fleet of ocean-going submarines. When he is full-fledged, he returns to his homeland, cleans up the scourge of aberrations, uses the deep sea as his foundation, defends the gate of China, and restarts the fire of human civilization.
