Creating Demonic Cultivation Techniques against Non-human Races - Chapter 27: Demon Thought Possession, Eternal Fall into Abi! The Fourth Grade Attacks, Slashed Away with One Strike!

I had thought that my life couldn’t get worse when I walked in on my fiancé cheating on me with my best friend. But after a series of unfortunate events, I opened my eyes in a world that I had only read about in a webnovel, the Erudian Empire, ruled under the domineering, bloody reign of Emperor Helio.

The worst part?

I’m not even the main character! Reborn as Winter Royberg de la Erudian, I am the pitiful side character who is discovered to be a royal bastard princess due to a certain physical trait only the imperial bloodline possesses. But I know the end of Winter’s story and the unwanted royal punching bag is framed as a witch and killed at age 16 on the guillotine due to the scheming of the cruel empress.

An aloof, murder happy father? Check.

Psycho half-sister? Check.

Meddlesome author who wants me to follow the script? Double check!

I don’t want to die an early death again, so I’m determined not to ever be discovered as a royal again. But before I know it, I’m trapped in a palace of blood and opulence playing tricky games of power, games I have no clue how to win. How will I survive to adulthood in the imperial palace and get my happily ever after? And am I really the only person who fell into this world?

- Description from novelbuddy

To exact revenge on her fiance who cheated on her, Xing Shu plotted against her fiance’s uncle, Cheng Lang. “Was my nephew unable to please you?”

On a large, messy bed, Cheng Lang pinched Xing Shu’s chin. The black Buddhist bracelet around his wrist swayed from side to side. Everyone said Cheng Lang was a religious man who stayed away from women.

However, after sleeping with him for a night, Xing Shu expressed how it was actually easy to manipulate him. She only needed to say sweet things to him in a soft, gentle voice, and he’d give her anything she wanted.

“Mr. Cheng is only putting on a show with Xing Shu. He’ll dump her very soon!”

“Xing Shu is a shameless woman. Mr. Cheng would never fall for someone with ulterior motives like her!”

Everyone in Jing City waited for her to make a fool of herself, but nobody knew how Cheng Lang pinned her against the bed at night. “Xing Shu, mention getting a divorce again if you dare.”

Ever since then, Cheng Lang, a man who once belonged on the altar, was brought down by Xing Shu. He experienced what it felt like to be in a relationship like a normal person, and he found joy in it.

He found out that he is in a world similar to our own with a timeline akin to early twentieth century.

Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout.
