Pokemon, a genius scientist who traveled from one piece

Under the azure sky, a Pidgeot led a flock of Pidgeys, soaring across.

On the grass, gentle wild Pokémon like Rattata and Oddish were dozing, snoring against the base of a large tree.

Opposite them, under another large tree, a boy who looked to be around ten years old was blankly staring at these snoring wild Pokémon, muttering to himself:

"So, you can transmigrate twice, huh?"

That's right, this was Su Sheng's second transmigration.

His first transmigration brought him to the world of One Piece.

There, he joined Vegapunk's science team and achieved even greater technological feats than the man himself.

Unlike Vegapunk, who, despite possessing technology far ahead of his time, always wavered in his stance, sometimes getting close to the Revolutionary Army, sometimes choosing to serve the World Government.

Su Sheng's position was quite firm, which was… neither the Navy nor the Pirates were good people!

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

Yes, cooperate with Sabo, not Monkey D. Dragon.

Because Su Sheng always felt that the man with the slipper tattoo on his face was unreliable, always sweating when something happened.

His subordinates were captured, and his good brothers were even green-hatted.

Yet, he still didn't act!

In the end, Su Sheng led his Seraphim army, united with Sabo and the four commanders of the Revolutionary Army, to launch a full-scale war against the World Government, led by the Celestial Dragons.

The scale of the war was no less than the Marineford War.

Finally, when they fought to the Empty Throne, facing Imu, that androgynous monster.

Because he didn't understand the opponent's ability, he fell for a trick.

Alas, if he had advanced in the Pokémon world beforehand, learning how to prevent direct attacks on trainers, this wouldn't have happened.

But what Su Sheng never expected was.

After transmigrating to the world of One Piece and dying once, he could actually transmigrate a second time!

To the world of Pokémon.

"Goo-goo-goo~"

Just as Su Sheng was "reminiscing about the past glorious years," his stomach suddenly issued a muffled, thunderous protest.

"Speaking of which… it's been two kun since I transmigrated, and I haven't eaten anything."

Su Sheng patted his stomach.

"Nado nado~"

As if hearing Su Sheng's stomach protest, an Oddish launched a Razor Leaf, accurately slicing the fruit off the tree above Su Sheng's head.

Several Pecha Berries landed precisely in front of Su Sheng.

"Hmm? Is it for me?"

Su Sheng's eyes lit up.

"Nado nado~"

The Oddish nodded with a smile.

"Good boy, good boy~ What a good kid."

Su Sheng walked up, picked up the Oddish, and stroked it a few times.

After asking which city was closest to here, Su Sheng picked up the Pecha Berries and waved goodbye to the Oddish.

"What a wonderful place, like a utopia, a world apart from that ghostly world in my previous life."

Su Sheng chewed on the Pecha Berries while complaining as he headed towards the city.

In his previous life, he read One Piece fanfiction, where the protagonist either became a pirate or a marine after transmigrating.

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

Although there were some exceptions, most of them were rotten to the core.

...

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

"I should find an adult and ask where this is."

Su Sheng thought to himself.

He needed to figure out which region he was in first.

If it was Kanto, he planned to go and rely on Professor Oak, who wasn't Ash's father but was better than Ash's father.

With the technology he learned in the world of One Piece, it wouldn't be a problem to become an assistant and gain a foothold with that ramen-loving old man.

"Hmm, her it is."

Su Sheng noticed an old woman by the street ahead.

"Could you really be… my Eevee?"

However, as Su Sheng approached, he heard the old woman's trembling, extremely frightened voice.

Getting closer, he saw a Umbreon squatting in front of her.

It should be her Pokémon.

However, the old woman, a trainer, held her hands in front of her, her legs trembling violently with fear, as if she was about to fall to the ground in the next second.

The Umbreon on the opposite side was not doing any better.

Seeing her beloved master showing such an attitude towards her for the first time, she only felt that the world was collapsing.

The old woman trembled and said, "This, this dark skin… and, and the red eyes… too, too ominous… too scary!"

Umbreon's pupils dilated sharply, and her small body trembled as if electrocuted.

"Tsk tsk… it seems this world isn't as good as I thought."

Su Sheng thought to himself.

Just as Umbreon suppressed the pain in her heart and wanted to take a step forward to comfort her master.

The old woman subconsciously took a step back.

"Don't, don't come near me!"

This step left an irreparable rift between her and Umbreon.

"Don't, don't come over… don't come over…"

The old woman turned to run away, but Su Sheng blocked her path.

"Hey, Grandma, haven't you seen an Umbreon before? It's also an evolved form of Eevee, there's no need to be so afraid, right? 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 the game.

"Wh-what Umbreon? Quick, quick, let me through! You, you can have it if you like!"

Saying that, the old woman ran past Su Sheng.

Without a moment's hesitation.

"Really? She doesn't even know about Dark-type Umbreon?"

Su Sheng turned his head to look at the old woman's back, then looked at the Umbreon with lowered eyes and a deathly pale face.

"Emmm… Little Black, why don't you follow me for now? After I research a way to devolve you back into Eevee, how about you go back to your master?"

Su Sheng thought for a moment and said.

Upon hearing this, the pain on Umbreon's face instantly turned to shock.

This human child must be crazy?

She had never heard of an Eevee being able to devolve after evolving!

However, what Umbreon didn't know was that after transmigrating, Su Sheng's scientific research heart began to stir.

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

Evolution was naturally one of the projects.

"But during this time, you have to be responsible for helping me find food, I'm not like Monkey D. Luffy, I don't work for free."

Su Sheng then reminded.

The reason why he joined forces with Sabo to fight the World Government in his previous life was not purely because of a sense of justice.

More importantly, after the World Government saw that Vegapunk had ulterior motives, they set their sights on him.

Although Su Sheng didn't think he was a great person, he was at least a person.

He didn't want to get involved with those brain-dead people.

Since that was the case, it was better to strike first.

Thus, there was the great battle where Su Sheng joined forces with the Revolutionary Army to attack the Holy Land of Mary Geoise.

"Bu-ee~"

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

She was now homeless, did she have any other choice?
