The Incubus System - Chapter 683: A Demon Beneath A Human’s Skin

It is an era of artificial superintelligences, interstellar travel, gene medicine, and virtual reality worlds. Far into Earth’s future, 15-year-old Gu Ding is a student of Cerulean Military Academy by day, and tavern waiter by night. His ambition: Become the space pirate with the highest bounty offered by the Universal Federation Government. With the help of Neptune, a neonate super-intelligence, Gu Ding finds himself thrust into a galaxy of shadowy organizations, political underdealings, and otherworldly forces that lie beyond human comprehension…

Seria, a social outcast, has changed.
Seria Stern, the wicked woman who made everyone tremble with fear, was now calm.

In fact, she wasn’t just changed, she was a completely different person.

The moment she realized that she had possessed the body of the villain Seria, in a romance novel, she had a hunch about the future and decided to live low.

She would avoid kidnapping and harassing the original heroine, hence preventing her death by decapitation at the hands of Kalis, the second male lead.

In order to avoid that, she had to fix her bad relationship with Kalis and even healed his injured arm.

Thanks to that she got engaged with him, so it’s all worked out.
Finally, the original heroine returned, and her husband, Lesche, should be on good terms with her now.

“I’ve been waiting to escort her, so…”

Lesche asked, resolutely cutting off Kalis’ words.

“Miss Seria, it would be better for you to choose. With whom would you want to go with?”

Something was strange.
The original, wasn’t it perfectly fine?

She is the slow-witted idiot of the Prime Minister’s Residence. Everyone bullies her. He is the most respected and unfeeling Prince, with frightening ability and absolute envy! Together, they are conferred an imperial edict of marriage.

She acts stupid and tries to decline in every way possible while he despotically escorts her into the wedding…… everyone ridicules the match, but no one knows that the “idiot” has transformed from a loser into a talent.

After the marriage, when they encounter the Empress Dowager examining the room, they act in concert with each other and pretend to be two mandarin ducks deeply in love. Afterwards, she laughs, “The performance has ended. Your highness, please return.”

He laughs softly, “Since you’ve got onto this Prince’s bed, don’t even think of getting off.”
