Survival at Sea? My Vehicle Is a Turtle!

[Sci-fi + post-apocalypse + leveling up + farming + no do-gooder heroine + lighthearted wish fulfillment] She wakes up to find the world turned upside down. All of humanity has been transported to another world, where they must survive at sea. In this boundless ocean, danger and opportunity go hand in hand. But while everyone else has a speedboat, a luxury yacht, or at least a pirate ship or ghost ship, why is her vessel a giant turtle?! Li Li looks down at the smooth turtle shell beneath her feet, less than one square meter in size, and feels like crying. She’s terrified that if the big guy gets excited and decides to take a deep-sea dive, she’ll be done for. Luckily, her turtle is exceptionally clever. It not only understands what she says, but can also navigate on its own, and only needs one fish per hundred kilometers. While everyone else shivers in storms and goes hungry because they can’t find food, Li Li enjoys the good life atop her turtle, which has evolved into a Black Tortoise. When people try to team up and steal her resources, they don’t even get to see Li Li before a huge mouth swallows them whole.
