Naruto System in One Piece - Chapter 68

What would you do if your planet ceased to exist after a nap?

Once upon a time, there was a princess…

Scrap that.

Once upon a time, there was a hermit called Yao Si.

She was an orphaned hikikomori who lived a peaceful and mundane life in her cosy little apartment.

Just when she thought she’d live out the rest of her mundane days… she died.

By a strange twist of fate, she was somehow turned into a vampire, even worse, a fifth-generation weakling with no combat ability at all.

Vampires had their own little secret society, cultural feuds, and called themselves bloodlings.

With the threats of another civil war among the bloodlings, Yao Si remained composed.

‘Even if this war of bloodlings rages on again, it will need a miracle to affect me,’ she thought.

So, a miracle occurred…

When she was woken up from a millennnia-long nap, she found that her beautiful mother planet Earth had ceased to exist.

Even the oldest bloodling in the entire universe was now one of her grand [ times infinity] child.

Everyone will have to call her “ancestor” from this moment onwards!

The peasant Yao Si had successfully revolted and taken charge, let’s see who dares to call her a weakling anymore!

“Hey! You, that guy over there!

“Yes, you.

“Come on, let’s fight, if I lose, I will call you ‘dad’!”

So… she has a new dad.

Yao Si “…”

Mu Xuan “…”

Eli was transmigrated to a world of magic and became immortal.

He had endless life and could never die.

“Huh? I’m talentless? Then, I’ll just train for as long as I need, even if it takes 1000 years. That should be enough for me to become strong.”

“The skill is hard to learn? Then, I’ll take a few dozens of years to research it. There’s no way it’s that hard, right?”

“What? I can sacrifice my life force to gain spirit power? That’s a bargain!”

“The enemy is here? Hell, I’ll just hide for 10000 years. Let’s see if he can outlive me. I’ll come out once he’s dead.”

This is the story of an immortal who first struggled to live in the world of magic until he became strong enough to slaughter endless worlds.

In a world intertwining magic, knights, and burgeoning technology, young Leonard grapples with memories of a past life in the modern world after waking up reborn in this new, tumultuous reality. Separated from his family amidst a devastating conflict, Leonard's life takes a precarious turn when he is taken under the wing of Alfonso, a reclusive and somewhat deranged wizard. Under Alfonso's tutelage and the rigorous demands of a daily task panel that rewards him for mundane chores with experience points, Leonard finds himself thrust into a harsh survival regime, far removed from his previous life's comforts. His daily life oscillates between mastering arcane spells, learning the delicate art of Earth Ring meditation, and handling the meager sustenance at the prison-like estate where he and Alfonso reside.As Leonard's skills grow, so too does his awareness of the wider conflicts that plague this world, blend of industrial revolution-era technology and dark magical forces. The task panel becomes a strange companion, guiding him through tasks that blend the mundane with the magical, pushing him to grow stronger. Amidst the backdrop of this grim reality. The complex interplay of power, survival, and the echoes of his former life drives Leonard to not only master his new abilities but to unravel the mysteries of this world and perhaps find a way back to his family, despite the cold indifference of his master. Each experience point earned and each new ring formed in his meditation brings him closer to understanding this world's brutal truths and his own place within it.

Tired of the schemes and strifes of city life, Bei Feng finally returned to his hometown in the countryside

While picking asters ‘neath the Eastern fence;

My gaze upon the Southern mountain rests;

Rearing a few chickens and ducks, I shall lead a simple and leisurely life!

However, who would have thought that fate would play a huge joke on Bei Feng? All kinds of magical items and beings of the Myriad Worlds could actually be fished out of the Ancient Well in his yard!

Even a chicken reeled out of the well ended up chasing Bei Feng all over the yard and beating him black and blue! Speechless and aggrieved, he asked the Heavens: if, that day, he’d fished out a Dragon instead of a chicken, what would’ve happened to him!
