East Blue, Loguetown.
At only six years old, Roy watched a thief shoot the middle-aged woman whose wallet he had just stolen.
His pupils shrank in shock.
“The world of pirates is too dangerous.
It isn’t nearly as peaceful as it looks in the anime!”
Roy had transmigrated here.
His current body was only six years old.
With no one to rely on, he had to be twice as cautious if he wanted to survive in the world of One Piece.
Just as Roy was preparing to leave the scene of the shooting as quickly as possible, a voice suddenly rang out in his mind.
[Detected that the Host has successfully survived in the One Piece world for ten days.
The Strongest Travel Check-In System has begun binding!]
[Binding successful!]
After hearing the voice in his mind, Roy froze for a moment, then his heart filled with wild joy.
“I knew every transmigrator had a cheat!”
“System, can you introduce yourself?”
Roy asked.
In the novels he had read, any mature system would answer on its own after being asked such a question.
[The Host may perform travel check-ins at famous locations throughout the One Piece world.]
[After checking in at a location and staying there for half a month, you will receive a reward!]
The System’s voice rang out in Roy’s mind.
“What about a beginner gift pack?
Do I have one?”
After hearing the System’s explanation, Roy suddenly asked.
He had only asked casually, but to his surprise, the System actually answered again.
[You have one beginner gift pack waiting to be claimed.
Please claim it yourself, Host!]
The System’s voice continued in Roy’s mind.
Was a beginner gift pack standard for systems?
He wondered what exactly would be inside it.
“Claim it!”
Roy claimed it without the slightest hesitation.
[Claim successful.
You have obtained the Wood Release kekkei genkai!]
“The Wood Release kekkei genkai?”
“But I don’t know how to use chakra.
Can Wood Release be used without chakra?”
Roy frowned and asked.
In the Naruto anime, releasing ninjutsu required chakra.
[The Host may use physical stamina in place of chakra!]
After hearing Roy’s question, the System answered.
“So that means using Wood Release will consume my stamina?”
Hearing the System’s answer, Roy let out a small breath of relief.
“But even though I’ve obtained the Wood Release kekkei genkai, I’m only six years old right now.
My body hasn’t even fully developed yet.
There’s no way it can support me using Wood Release!”
Although Roy had obtained the Wood Release kekkei genkai, he had not received any corresponding ninjutsu.
That meant he still had to develop the techniques himself—or should they be called skills?
Since chakra was no longer required, they probably could not be considered ninjutsu anymore, right?
Still, as a transmigrator who had watched Naruto, he knew a thing or two about the techniques of Hashirama Senju, the “God of Shinobi.”
So, to develop Wood Release, Roy only needed to use Hashirama Senju’s techniques as a reference.
If he wanted to train and develop Wood Release, a bustling town like Loguetown was clearly unsuitable.
Therefore, Roy planned to continue staying in Loguetown for fifteen days.
Once the check-in was successful, he would head to an uninhabited island and train bitterly to develop his Wood Release.
[You have not checked in today.
Would you like to check in?]
The System’s voice rang out in Roy’s mind again.
“Check in!”
Roy immediately chose to check in.
[Check-in successful.
You still need to check in at Loguetown for fourteen more days before you can receive a reward!]
After the check-in succeeded, the System notification rang out.
“Fourteen days is fine.
During these fourteen days, I can find a wooden boat and a nautical chart, then head to an uninhabited island to train and develop Wood Release.
I’ll lie low until this six-year-old body of mine grows up!”
“In this dangerous world of pirates, even if I have Wood Release, I still don’t have enough power to protect myself.
After all, I’m still too young.”
“Hashirama Senju’s ability was Wood Release.
Mine might just be Sapling Release.”
As his body grew from childhood into adulthood, perhaps Roy’s physical strength would eventually be enough to support large-scale Wood Release.
Time flew by like an arrow.
The next fourteen days passed in the blink of an eye.
During these dozen or so days, he insisted on checking in every day.
At the same time, he also prepared a boat and a nautical chart.
He spent almost all of the inheritance left to him by his parents, who had already passed away many years ago, leaving very little behind.
When Roy dragged the wooden boat to the shore by the harbor, he began his fifteenth check-in.
[Check-in successful.
You have obtained a Super Gene Enhancement Serum!]
[Would you like to use the Super Gene Enhancement Serum?]
This had come exactly when he needed it.
Roy had originally been worried about his physique.
With this Super Gene Enhancement Serum, he no longer had to worry about casually using his ability and having all his stamina drained at once in the future.
“Use it!”
After Roy chose to use it, the Super Gene Enhancement Serum entered his body through the System’s operation and began to transform and strengthen him.
About seven or eight minutes later.
Roy woke from his seated position.
“Comfortable.
My current strength should be enough to compete with a grown man—maybe even stronger than one.”
Roy thought to himself.
Right now, he was only a six-year-old child, yet after being transformed by the Super Gene Enhancement Serum, his physical stamina was already comparable to that of a grown man.
This had already exceeded his expectations.
Besides that, the serum’s greater effect was that it had given him limitless potential.
After completing his travel check-in at Loguetown and receiving the strengthening effect of the Super Gene Enhancement Serum, Roy boarded the small wooden boat and set off toward an uninhabited island not far away.
He planned to train and develop Wood Release on that uninhabited island.
Once his strength was powerful enough for him to roam the seas, he would sail out again and continue traveling to famous locations for check-ins!
…
…
In the first year of training Wood Release, Roy gradually began to familiarize himself with his Wood Release kekkei genkai.
In the second year of training Wood Release, he had already developed quite a few Wood Release skills.
In the third year, he defeated the strongest beast on the island.
In the fourth year, he used Deep Forest Emergence for the first time and nearly collapsed from exhaustion.
The fifth year, the sixth year, the seventh year…
The eighth year, the ninth year, the tenth year!
On an uninhabited island…
He trained bitterly for ten full years!
