Island survival I have got F- rank talent

Stranded on a primitive, average-sized island after a catastrophic shipwreck, Lily, a perpetually cheerful young woman, faces certain doom. Her only hope? An F-rank talent: 'Random Expansion.' This seemingly useless ability adds an infinitesimal amount to a single random property of any target she touches, requiring hundreds, even thousands, of uses to achieve a noticeable effect. As the island's untamed wilderness and increasingly bizarre flora and fauna threaten her survival, Lily must relentlessly grind her talent, turning pebbles into slightly sharper stones, weak vines into marginally stronger ropes, and bitter berries into barely palatable sustenance. But the island holds secrets far deadlier than its wildlife, and Lily's slow-burn growth might not be enough to counter the encroaching darkness. Can an F-rank talent truly save her, or will she become just another forgotten victim of this cruel paradise?
