History's Strongest Son-In-Law Living With The In-Laws - Chapter 18

A girl Alicia lived as an orphan in a world of sword and magic Ciel.

One day, she learned that she was an “otome game’s heroine”. Even her parents’ death was simply a part of the scenario. Alicia judged the heroine’s setting as 「nonsense」and discarded it decisively. She introduced herself as adventurer 『Aria』, gradually mastered multiple weapons and magic, and grew to become the 「Ash Crowned Princess of Slaughter」! But, by accepting a request to guard the “villainess”, before she realized it she got dragged into the stage where nobles quarreled against each other――？

「I am “I”. I’m not a game character!」

Create weapon! Train your body!

Survive the fighting against powerful enemies and smash apart the otome game!

A sublime and exhilarating other world battle fantasy with charming fighting heroine!

By a series of freakish accidents, she provokes the feared and mysterious “God of Night”.

When someone bullies her, he says, “Only two types of people bully my wife: those who haven’t crossed her path, and those who have already died. Which do you want to be?”

When someone questions her, he says, “Everything my wife does is right! Those who disagree can have a little chat with me!”

When he goes home, he pleads in a low voice, “Wifey~ Can I not sleep in the study today?”

“You can consider sleeping on the streets.”

“Well, I’ll sleep in the study, then.”

At night, he abducts his freshly-showered wife into the study. She shrieks, “Sheng Nanxuan! What are you doing?!”

“Sleeping… in… the… study!”

The next day, his wife dashes out of the room with tears in her eyes and a sore waist. That isn’t what she meant by “sleeping in the study”…

One morning after being struck by lightning, Ye Wenxuan inexplicably gained the superpower of being able to generate electricity.

If he jammed his finger into one of the generator terminals in an electricity power plant, he could provide a year’s worth of power for 3 Tier 1 cities simultaneously, receiving the name “the mobile nuclear power plant.”

The country’s electrical company’s boss held his hand, speaking emotionally: “Comrade ah, the country’s future electrical development will all depend on you!”

Ye Wenxuan: WTF

Later, the “mobile nuclear power plant” was dispatched to be a bodyguard for a local tyrant.

Xing Yuan coldly said: “Just now did you or did you not electrocute me?”

Ye Wenxuan pointed to the heavens and swore: “I am an honorable employee, how could it be possible for me to make a move on my employer!”

Later on…

he made a move.
