Fish Girl Evolution [Cultivation LitRPG]

She's a fish. She's a girl. And she's going to evolve. Shu wasn't always a fish. She wasn't even always Shu. However, after giving her life to save a child, she is rewarded (?) with reincarnation into a world of cultivation and immortals. That doesn't go as planned though, and she dies almost instantly, her soul fed to a mindless koi. Now, not only is she stuck in the body of a koi, her owner is the very same man who cut her second life short. Her only saving grace is the System she was granted to help her get accustomed to the new world, and the information it provides. With it, she can learn to both cultivate and evolve! What to expect: - Monster Evolution shenanigans - Xianxia shenanigans - No romance - Bubbles
