The vision came to an end.
"As expected, once I add the Chakra Extraction Technique and chakra, the target world changes. Looks like my guess was right—Arceus doesn't want the chakra system to be acquired by humans in its world."
Akira stroked his chin in realization.
Once might be coincidence. Twice was definitely not.
"But I didn't expect this exchange to connect to the Harry Potter world. So… what I got this time is a ring?"
With that thought, two items appeared in his hand.
One was a silver ring.
The other was a crystal.
"Oh?"
Akira was slightly surprised. "There's actually a second item? This is… an inheritance crystal? Unfortunately, it's not Nicolas Flamel's complete inheritance."
The information that surfaced in his mind told him that the crystal contained a meditation technique along with Flamel's lifetime experience with the Undetectable Extension Charm.
[Spatial Ring]: Contains a vast internal space spanning a hundred kilometers in radius. It can not only store items but also sustain living beings, comparable to a small world. (Your Exchange Talent found the original activation method too cumbersome and has modified it to be activated via chakra or mental energy.)
[Nicolas Flamel's Inheritance (Simplified Version)]: Contains a meditation technique created by the legendary alchemist and his lifetime experience with the Undetectable Extension Charm. (Your Exchange Talent has thoughtfully adapted the meditation method to align with the Naruto world's rules and modified the spell to function with chakra.)
…
"Wow… these are both incredible."
Akira's eyes lit up as he read the descriptions.
The Spatial Ring alone was already an extraordinary treasure. It could house living beings, effectively serving as a hidden mobile base.
With such a massive internal area, he could easily construct a castle inside for living, build laboratories for research, cultivate plants, raise animals, and even establish a training ground for ninjutsu practice.
In critical moments, it could also serve as a refuge or a means of escape. He could even hide people he cared about inside to keep them safe.
And all of this could coexist.
Because the space was simply that large—one hundred kilometers in radius.
It was even bigger than the entire Hidden Leaf Village.
Compared to this, something like Newt Scamander's suitcase was nothing.
More importantly, this ring was essentially permanent.
Although the Beast Space could also store items, its scale was limited, and it was far better suited for cultivation and nurturing, where it could fully utilize its growth and evolution amplification effects.
"Nicolas Flamel really is amazing… what a pity I didn't get his full alchemy inheritance."
Akira felt both excited and slightly regretful.
Who knew when he would get another chance to exchange with Flamel again?
He hadn't yet figured out a stable pattern for that world.
Without hesitation, Akira pressed the inheritance crystal against his forehead.
In the next moment, the crystal turned into a stream of light and entered his mind. A complete meditation method appeared within his consciousness.
Through meditation, one could directly enhance mental strength.
Akira tried cultivating it briefly and found the effect quite good. With long-term practice, it would steadily increase his mental energy.
He immediately decided to dedicate one to two hours daily to meditation.
Mental strength was extremely important for a ninja.
It affected chakra reserves, genjutsu aptitude and power, learning ability, perception, and more.
In short—it was crucial.
Obtaining this meditation technique made Akira extremely satisfied.
At the same time, a large amount of knowledge regarding the Undetectable Extension Charm also appeared in his mind.
After spending over half an hour digesting it, Akira fully grasped this chakra-adapted version of the spell.
"Undetectable Extension Charm."
He opened his eyes, raised his hand, and pointed at the wall ahead, channeling chakra.
Instantly, the wall seemed to recede, and the room itself expanded.
However, when Akira stepped outside to check, everything looked completely normal. The wall hadn't moved at all.
Yet inside, the space had undeniably increased by about thirty percent.
Only when the chakra sustaining the spell was exhausted did the effect fade.
"Next, I need to see if I can permanently fix this spell onto objects and create stable spatial tools."
Akira began planning.
If successful, this would become another valuable asset under his control—something he could even use to make money in the future.
After all, he was currently quite short on funds.
"Maybe I should send shadow clones out into the ninja world to explore and earn resources?"
The thought crossed his mind.
But he quickly shook his head.
"Not yet. My shadow clones can't last long enough, and their strength still isn't sufficient."
Only when they reached the level of Hashirama's Wood Clones could he truly execute that plan.
…
Early the next morning, Akira sent an additional shadow clone to the commercial district to purchase various materials.
When his main body returned home that afternoon, he immediately began experimenting with crafting long-lasting spatial items.
This wasn't as simple as casting the Undetectable Extension Charm on a container.
To make the effect permanent, special materials were required to engrave magical runes—modified into chakra-compatible inscriptions—onto the object.
These runes would stabilize the spell while also allowing the item to store chakra to sustain the effect.
That was the foundation of a long-lasting spatial tool.
Even so, such items would still have a lifespan. Once the runes degraded, the tool would cease to function.
Ideally, rune engraving materials should come from magical creatures or possess strong magical conductivity.
However, since this was a chakra-adapted system, Akira theorized that materials capable of conducting chakra would work just as well.
Such as:
Ninja beast blood, fur, bones, and similar materials.
He gathered these through purchase and hunting, conducting multiple experiments.
In the end, he even acquired 200 grams of chakra-conductive metal from a ninja tool shop.
After extensive testing, he reached a clear conclusion:
Chakra-conductive metal was the best.
Sealing scroll materials came second.
Ninja beast materials ranked third.
