The payment from Ra's al Ghul was secured.
Upfront.
Clean.
Professional.
I accepted the briefcase without hesitation and gave a simple order through a White Zetsu clone:
Kakuzu and Hidan would be transferred to the League of Shadows as temporary operatives. Structured cooperation. Controlled alignment. Strategic partnership.
They would gain influence and battlefield experience.
And I would gain something far more valuable.
Growth.
Back inside the base, I returned using the Flying Thunder God technique.
Instant repositioning.
No travel time.
No vulnerability window.
The moment I arrived, I felt the system respond.
Points converted.
Energy stabilized.
And I activated the purchase.
Double Chakra — 3,500 points.
The effect was immediate.
My chakra reserves surged outward, then settled into a denser, expanded core.
Then I purchased it again.
The second application layered on top of the first.
Not merely doubling twice in sequence in a simple way — but compounding.
The result was staggering.
My chakra capacity had increased exponentially.
With an Uzumaki body enhanced by Sage traits, my reserves were already immense.
Now they were beyond that threshold.
This wasn't just quantity.
It was sustainability.
I could maintain high-output techniques for extended periods.
Large-scale barrier formations.
Continuous genjutsu pressure.
Repeated high-cost ninjutsu.
Extended battlefield dominance.
Days of combat without exhaustion were now realistic.
With this level of chakra, I could rival top-tier chakra monsters.
The comparison points in my mind became clear:
Jinchūriki-class reserves.
Possibly approaching the scale of Hashirama-level output.
Whether matching or exceeding depended on application, but the raw reservoir was now in that territory.
And that was before factoring in efficiency from my talents.
The system points were gone.
But the investment was irreversible.
Permanent amplification.
I immediately shifted focus back to technique development.
Inside the base, hundreds of shadow clones continued working.
Every clone was operating under structured assignment.
Development cycles were staggered.
Mental load was managed carefully.
Clones dispelled in sixty-second intervals to prevent overload accumulation.
The original body remained stable.
Controlled.
Strategic.
With the new chakra capacity, advanced techniques became even more viable.
I began refining my existing arsenal.
Rasengan Line Development
Using enhanced chakra control, I optimized multiple variations:
Standard Rasengan for rapid deployment.
Ōdama Rasengan for high-density impact.
Wind Release: Rasenshuriken for internal chakra network destruction.
Miniature throwable Rasenshuriken variants.
Spiralling Absorption Sphere for battlefield chakra drainage.
Vanishing lightning-infused Rasengan for stealth engagement.
With my increased reserves, sustaining advanced Rasengan variants became far easier.
The key improvement wasn't just power.
It was stability.
The shape manipulation talent made compression smoother.
The Tobirama-style development talent allowed structural refinement.
The result was cleaner chakra rotation and reduced waste.
Lightning Techniques Enhancement
Next, I expanded lightning-based applications:
Chidori Senbon for precision ranged disruption.
Chidori Spear variants for extended reach.
Chidori blade integration for enhanced cutting power.
Full-body Chidori Current for defensive stun fields.
Lightning Beast Tracking Fang for long-range pursuit.
Susano'o-integrated lightning constructs for large-scale offense.
Natural lightning amplification techniques similar in principle to Kirin.
With massive chakra reserves, sustained lightning output was now realistic rather than situational.
Continuous area control became possible.
Sealing Integration
Most importantly, I began integrating fuinjutsu principles into offensive constructs.
Magnet Release-style sealing Rasengan variants.
Chakra-binding compression spheres.
Target-lock containment formations.
With my sealing mastery, even standard techniques could now carry suppression layers.
That meant battlefield control.
Not just damage.
Control.
Three days passed.
Technically.
But with hundreds of clones working simultaneously, the actual development time equated to thousands of hours.
Over seven thousand hours of structured refinement.
Technique iteration.
Optimization.
Stress testing.
Improvement.
When the clones dispelled, the knowledge returned in waves.
My mind processed it seamlessly.
No overload.
No instability.
Only growth.
The Akatsuki had expanded influence.
Financial stability was improving.
Strategic alliances were forming.
And my personal power had just crossed into a new tier.
Not reckless growth.
Measured escalation.
The Justice League would notice the shifts in chakra signatures eventually.
But by then, the gap would already exist.
And now, with doubled reserves compounded twice…
My next step was obvious.
Refinement of large-scale sealing frameworks.
If I could combine this chakra level with advanced fuinjutsu structures…
Entire battlefields could be reshaped.
And that was only the beginning.
