My Muscle System in the Mage World - Chapter 394 Reapperance of the Supreme Will, Nina appears again

I put all the warning tags to give myself creative freedom, but the story isn't filled with excessive gore or swearing.This is my first time writing other than for school projects. The gender-bender tag is only for the beginning because I wanted to try writing from a female's perspective and needed an excuse for why my MC reads a little tomboyish. The gender-bender fades into the background over the first few chapters; please don't let the tag keep you from trying out my story.Synopsis:Second chances are rarely earned and even rarer given. Follow a new life in a new world where anything is possible. Our MC wakes up, stuck as a baby, needing to decide how she will live her new life. Let's see what future she can forge when hard work rewards her with status points and skill levels.Author's Note: I'm currently slowly going back and rewriting my earlier chapters, so if you're starting to read this for the first time, try not to be alarmed if the quality suddenly goes down after reading a few chapters. I started writing this story almost three years ago, and I think I've improved as a writer since then. I appreciate your understanding; enjoy.

Upon meeting the girl who would become her adopted younger sister, the duke’s daughter Christina regained memories of her previous life. Through those memories, she learned that her new sister, Mishuli, was the heroine of a certain story. And though the story depicted a Christina who abused her sister, the real Christina turned into a siscon who spoiled Mishuli to no end.

She is a top-class spy, a poison specialist, but also a young and cute girl with a sinister temperament. In spite of her sweet and innocent appearance, she can complete any tasks without the slightest hesitation. One day because of an incomplete black magic, she was sent into the body of a girl who was deemed as a good-for-nothing. What kind of change will she bring to this continent?

A Prince said with bitter hatred, “I thought she was weak and easily bullied, therefore I broke off the engagement. I really didn’t expect she is such a shrewd girl. I made an error of judgment.”

The Crown Prince deeply sighed, “She is such a sexy evildoer! Obviously, she has a frail and tender body, but I am not able to overwhelm her…”

Finally, an Emperor hit the nail on the head, “She is just a bit two-faced!”

She answered, “You’re just a big pervert!”

The Emperor carried her into the room and said, “You are predestined to be mine! A two-faced girl and a pervert are a perfect match, right?!”
