Undersea City [Infrastructure + Management]

In New Calendar Year 279, the waves that had submerged the entire globe finally receded, revealing a stretch of land where humanity could live and multiply. After spending hundreds of years in the Dome Shelter, people stepped outside, and Blue Star was ready to be rebuilt. In New Calendar Year 356, humanity used technology preserved from before the disaster to rebuild civilization and began exploring the ocean floor. But after a century of development, the ocean floor was nothing like the records described. Everything seemed both unfamiliar and familiar. In New Calendar Year 357, a soul from before the disaster awoke, accompanied by a miraculous System. She became the owner of the first underwater city in Blue Star's history, and an unmissable milestone in the exploration of the ocean floor. Hundreds and thousands of years later, she would be hailed as the most dazzling jewel of the Great Age of Exploration. . From seafood smuggler to underwater city lord. Worldbuilding and management. The upcoming story is hard to categorize, and its subject suits an infinite-flow survival game better, so I'm restarting it. The romance will not take up much space. There will probably be many male side characters with one-sided crushes on the heroine. How much she reciprocates will depend on how the story develops as I write. Theme: Hardworking and brave people tirelessly explore the unknown and build a home for themselves
