An elf, a genius scientist who traveled from the world of One Piece.

Chapter 1: The Genius Scientist Who Traveled Through Time Again, and the Abandoned Umbreon

Under a clear blue sky, a Pidgey leads a flock of Pidgeys as they fly by.

On the grass, gentle wild creatures like Rattata and Oddish are snoring with their eyes half-closed on a big tree.

Under another large tree opposite, a boy who looked no more than ten years old was staring blankly at the snoring wild Pokémon, muttering to himself:

"You can time travel twice?"

That's right, this is Su Sheng's second time traveling through time.

His first time traveling through time, he was transported to the world of One Piece.

There, he joined Vegapunk's technology team and achieved even greater technological accomplishments than his colleagues.

Unlike Vegapunk, who, despite possessing advanced technology, has a constantly shifting stance, sometimes aligning himself closely with the Revolutionary Army and other times choosing to serve the World Government.

Su Sheng's stance was quite firm: all navy pirates are bad people!

Therefore, after mastering all of Vegapunk's technologies, Su Sheng chose to cooperate with Sabo of the Revolutionary Army.

That's right, it's a collaboration with Sabo, not Monkey D. Dragon.

Su Sheng always felt that the man with the slipper tattoo on his face was unreliable, and he was always sweating profusely whenever something happened.

His own men were arrested, and his best buddies were cheated on.

And they're not even going to lay a hand on it!

Finally, Su Sheng led his Seraphim army, joined forces with Sabo and the four commanders of the Revolutionary Army, and launched a full-scale war against the World Government led by the Celestial Dragons.

Its scale was no less impressive than that of the Marineford War.

Finally, when they reached the Void Throne and stood before Im, that freak whose gender was unknown.

Because they didn't understand the opponent's abilities, they fell victim to a dirty trick.

Sigh, if only I had studied in the Pokémon world beforehand and learned how to prevent direct attacks on trainers, this wouldn't have happened.

But what Su Sheng never expected was...

After being transported to the world of One Piece and dying once, he was able to travel through time a second time!

I've been transported to the world of Pokémon.

"Coo coo coo~"

Just as Su Sheng was reminiscing about the glorious past, a muffled, thunderous protest suddenly erupted from his stomach.

"Speaking of which... I haven't eaten anything since I transmigrated here two Kun time periods ago."

Su Sheng patted his stomach.

"Nado nado~"

Seemingly hearing Su Sheng's stomach growl, a Growlithe lashed out with its leaf blades, precisely severing the fruit from the tree above Su Sheng's head.

Several peaches landed precisely in front of Su Sheng.

"Huh? For me?"

Su Sheng's eyes lit up.

"Nado nado~"

Oddish nodded with a smile.

"Yoshi yoshi~ What a good boy."

Su Sheng walked up, picked up the walking grass, and stroked it a couple of times.

After asking which city was the closest to here, Su Sheng picked up the peaches and waved goodbye to the walking grass.

"It's such a beautiful place, like a utopia, completely different from that hellish world of my past life."

Su Sheng chewed on a peach while complaining as he headed towards the city.

I read One Piece fanfiction in my previous life, and the protagonist transmigrates to another world where he either becomes a pirate or a marine.

But in Su Sheng's view, neither side was a good thing.

While there are a few exceptions, most of them are rotten.

……

After walking for nearly an hour, Su Sheng finally arrived at this coastal city.

"Let's find an adult and ask where we are."

Su Sheng thought to himself.

Let's figure out which region this is first.

If it were Kanto, he planned to seek refuge with Professor Oak, who was not Ash's father but was even better than Ash's father.

With the technology she learned in the pirate world in her previous life, it wouldn't be a problem for her to gain a foothold as an assistant to that old man who loves instant noodles.

"Hmm, let's go with her."

Su Sheng noticed an old woman on the side of the street ahead.

"Are you really... my Eevee?"

However, when Su Sheng walked in, he heard the old woman's trembling voice, filled with extreme panic.

Upon closer inspection, it was discovered that a Umbreon was squatting in front of her.

It must be her spirit.

However, the elderly woman, who was a trainer, held her hands in front of her, her legs trembling violently with fear, feeling as if she was about to fall to the ground at any moment.

On the other side, Umbreon wasn't much better off.

The first time it saw its beloved owner treat it this way, it felt as if its world had collapsed.

The old woman said in a trembling voice, "This, this pitch-black skin... and, and red eyes... it's too, too ominous... too terrifying!"

Umbreon's pupils dilated sharply, and its small body trembled as if it had been electrocuted.

"Tsk tsk... It seems the world isn't as wonderful as I imagined."

Su Sheng thought to himself.

Just as Eevee was suppressing its inner pain, wanting to comfort its master and take a step forward.

The old woman instinctively took a step back.

"No, don't come near me!"

This step left an irreparable rift between her and Umbreon.

"No, don't come any closer... don't come any closer..."

The old woman turned to run away, but Su Sheng stepped in front of her first.

"Hey, Grandma, haven't you ever seen Umbreon? That's an evolved form of Eevee, there's no need to be so afraid, is there? Black is pretty cool, isn't it?"

Su Sheng vaguely remembered that in his previous life, he had put in a lot of effort to evolve Eevee into Umbreon when playing games.

"W-What? Umbreon? Get out of the way! You can have it if you like!"

As she spoke, the old woman ran past Su Sheng.

Without the slightest hesitation.

"Really? You don't know about Dark-type Umbreon?"

Su Sheng turned to look at the old woman's back, then looked at Yueyibu, whose eyes were lowered and whose face was ashen.

"Hmm... Little Black, why don't you come with me for now? Later, I'll figure out a way to make you revert back to Eevee, and then you can go back to your master, okay?"

Su Sheng thought for a moment and then said.

Upon hearing this, Umbreon's grief instantly turned into shock.

Is this human child insane?

I've never heard of the Eevee race being able to revert back after evolving!

However, what Yueyibu didn't know was that after transmigrating, Su Sheng's research ambitions as a scientist began to stir.

He couldn't wait to study the differences in power between spirits and Devil Fruits.

Evolution is naturally one of the projects.

"But you'll have to help find food during this time. Unlike Wang Luffy, I don't work for free."

Su Sheng then reminded him again.

In his previous life, the reason he joined forces with Sabo to fight the World Government was not purely out of a sense of justice.

More importantly, after the World Government saw that Vegapunk had ulterior motives, it set its sights on itself.

Although Su Sheng didn't consider himself a great person, he was at least a human being.

He didn't want to get involved with those idiots.

Since that's the case, we might as well strike first.

Thus began the great battle in which Susan and the Revolutionary Army joined forces to attack the Holy Land of Mary Geoise.

"Bu Yi~"

After a long while, Umbreon finally opened its mouth and responded.

Now that I'm homeless, what other options do I have?

I'm new here, so please be kind to me. I have a lot of drafts saved up, so please feel free to read.
