One Piece: Seaside System - Chapter 6: Marine Based -

A lowly child beggar, a noble prince, a monster viewed as the enemy of the entire world. If you possess all three identities at the same time, which identity would you choose to help you earn a better ending?

Thales did not have the answer.

He only knew that he came to a different and magnificent world, and he had to face a future that was as difficult to handle as a nightmare.

The glorious Empire had already been destroyed for one thousand years, the dying royal family suffered many problems, the legendary sacred battle had plenty of conspiracies, the divided world was in chaos.

But Thales had nothing.

The only thing he had left was an unswerving determination to preserve his own identity, bravery which would allow him to survive in a perilous situation, and a belief that he would never submit to principles he did not believe.

“A King does not gain respect by virtue of his bloodline. The bloodline’s glory rests on the deeds of the King.”

Darkness will baptize light. Fire will create true steel. The forbidden prince’s story starts here.

“Can’t I properly read stallion novels anymore!”

Shen Yuan transmigrated into someone who’d tormented the young male lead almost to death, the scum villain Shen Qingqiu.

It must be known, the original Shen Qingqiu ended up being carved alive by his disciple, Luo Binghe, into a human stick, a human stick!

Ten thousand “fuck your moms” rampaged through Shen Qingqiu’s heart:

“It’s not that I don’t want to cling to the male lead’s thighs, but who made him so fucking black. The type who seeks thousand-fold retribution!”

Why have all the female lead’s scenes been forcibly given to him.

Why, as a scum villain, does he need to constantly sacrifice himself, blocking knife and gun for the protagonist!

Shen Qingqiu: “…I think I can still save him, one more time.”

A gong who starts as a loyal dog of a small white flower, and ends up as a blackened, mental case of a maiden X a refined scum villain of a tsukkomi-holic shou

This is actually a dogblood story about a master-disciple pair never doing honest work, fighting monsters, and engaging in romance.

It’s also a story where the villain personally witnesses how the male lead transforms from a little sheep of a white lotus into a dark tyrant O(∩_∩)O~
