MTL - The Villain Has Something to Say - Chapter 88

What is a genius? Capable of comprehending any battle skill regardless of the skill itself and sweeping away the bottlenecks while cultivating a new technique; this is a true genius! He Yiming was originally an ordinary youngster in the He family’s estate with not too extraordinary aptitude in learning martial arts.

Shaman, a normal teenage girl falls asleep on the eve of her 18th birthday like any other night. She awakens to find herself in an unknown place in an unfamiliar body with an unhelpful voice in her head.

On top of that, she has gained fox ears and a tail, she also seems to have memories of this new world and the body she finds herself in. Unfortunately not all of the memories are clear and she must rely on this rpg like system in her head to both unlock these memories and guide her on a path home.

As she explores the world she finds that it is somehow both modern and old, with magic permeating every day life. Architecture reminiscent of the 1700s clashes with modern day conveniences enabled through magic.

Will Shaman be able to make use of her knowledge of video games and novels to take advantage of her rpg system in this new world? Or will she be dragged down and entangled by the darkness of the world around her as she searches for the truth behind her circumstances? Many eyes are upon her as she takes center stage in this new world.
