Started with a Leviathan Corpse, I Survived

On New Year's Eve, I traveled through time. Start with a Leviathan corpse, bound to the deep sea farming system. Mission: Carve a name on the skeleton, otherwise it will be erased. Cold sea water, strange giant shadows, unknown radiation - this is my New Year. While others were trying to survive in the wilderness, I started on hell difficulty, struggling to catch my breath at the bottom of the ocean 10,000 meters deep. But the system told me that this was once a testing ground for "sowers" and a hunting ground for "reapers". From scraping the first water with bone fragments, to building tidal farms, subduing the deep sea survivors, and lighting the fire of civilization... I, Lin Mo, a former aerospace engineer, want to rebuild the human city-state in this lightless abyss. "Warning: The water you are drinking contains an unknown neurotoxin." "Warning: There are planet-level creatures passing by 3,000 meters above." "Congratulations, you have achieved the achievement [Rusty Blade Beginner]." When the light of the alien twin stars finally penetrated the sea and shone on the steel city I built. My first signal sounded on the global channel: "Survival in the deep sea is over. Now, it's time to conquer the stars."
