One Piece: I'm Destined to Be the Son-in-Law King! - Chapter 1: A Burning Desire

The red meteor shower rained across the sky, a black fog engulfed the world.

After waking from a night of torture and agony,

Humans discovered they no longer dominated the world.

—The hunters have become the hunted.

After the apocalypse, I struggled for survival for ten bitter years, but ultimately couldn’t escape death.

But when I opened my eyes again, I had transformed from an ordinary 35-year old woman into a beautiful young man of 18.

A different gender, a world that is both familiar yet not, an apocalypse that has vanished without a trace, and an unexpected return of 17 years of youth.

Looking around, I discovered I had a powerful, protective big brother and a gentle, charming little sister.

Just as things couldn’t possibly look any brighter—

The end of the world came crashing down again.

And this time around, is it fight? Or flight?

Ye Fan accidentally obtained a billion crystal technology system, and since then, he has become out of control.

Android: You do n’t even have a mobile phone system. I want to make it impossible for you all!
Ye Fan: Sorry, I researched it out, it seems to be more powerful than yours!
BMW Benz: Our engines are famous all over the world!
Ye Fan: Sorry, I do n’t have an engine, I only have magnetic levitation, and the speed is only a few times that of yours. Do n’t worry, take your time!
…
Enemy: Is he still human?
Who can stop this!

- Description from Qidian

Being dragged forcefully, the young man found himself in a world where cultivation and magic exists. In this vast multi-worlds, the blood of the innocent and the blood of the guilt are spilled like it's nothing.

“I finally found you,” The words sent a jolt to his soul as an unknown yet familiar blurred memory played in his mind. Embraced by the unknown woman, they shared a kiss to his surprise.

Wearing a ring that held half of the power of his past life, the young man ventured to find his women and retrieve his lost memories.

Oh yeah, he was transferred naked.

“Brother, I loved you since before I was born!”

Corporate s*ave Yukimura Rina was reincarnated as the villainess Ekaterina from an Otome game. In her past life, she was obsessed with the brother of the Villainess, Alexei, but seeing him in real life is so much better than in the game! It’s just that, her brother’s upbringing is just so sad that she cries every time she thinks about it!

“Okay! I’m going to escape mine and my country’s destruction flag and make sure everyone lives happily!”

Thus, the villainess from the prestigious 400-year-old Yurinova Dukedom along with her sharp-tongued tendencies back when she was a corporate s*ave forge on forward. With her common sense and knowledge of history, she plans on saving her brother and overcoming all the game events.

For some reason, as time goes by, her talented brother becomes more and more of a siscon. Wait no, he was a siscon to begin with, but she’s more than happy to spend more time with her brother as a brocon and siscon.

And as time goes by, her plan to avoid the heroine and the prince death flag has become more and more messed up. Why? No no, the two of them are good people and good friends, but…

“Prince, stay far far away from me.”

Even so, the settings of the Otome game she played before are completely messed up in this world, nothing is the same.

Anyways! The evil villainess Ekaterina will do her best for the sake of her brother!
