Evolving into a Great Dragon From a Koi Fish - Chapter 12

Five hundred years later, a superhuman talent cultivated by the state perished during a mission, and his soul transmigrated, taking possession of the body of a young master from a prominent family who suffered from an anxiety disorder. From that moment on, his extraordinary life began, spanning across various fields such as business and medicine. Wherever he set foot, others could only look up to him.

After a shocking reincarnation, our hero opens her eyes to a new (and messy) world the last thing she remembers is reading Lady Viper’s Vow, a dark fantasy novel about a cruel, misunderstood villainess and her path of doom. But when our protagonist finds herself reborn right in the heart of an attack, she’s moments away from a second, way-too-soon death. Just as she’s about to face the end, a mysterious “system” pops up with a single mission: Level Up or Die Trying. It’s bossy, snarky, and her new best friend. As she levels up into a borderline-cheater powerhouse, she discovers her fate isn’t to be a hero, a princess, or even a sorceress, but to protect the one person no one ever expected her to side with: the villainess herself.

Back in 1998, an ordinary person who has been through, tired, cried, and fought, hopes to run down-to-earth and keep up with the trend of the times.
