Mermaid Supporting Female's Cultivation Record

After eight blissful years living carefree in a hidden seabed realm, little mermaid Yu Yinniao discovers she's nothing more than cannon fodder on Shi Ruilin's path to ascension—a nameless nobody who delivers massive cultivation resources and dies before the third chapter. Yu Yinniao thinks: we're all just ordinary beings, so why should she be a stepping stone for the female lead's rise? She decides to leave the secret realm, find the most reliable backer she can, and crash the ocean queen's ascension plan along the way. The male lead shows up later.
