The hidden laboratory was alive with the soft hum of chakra cores—Kirito's and the dozens of clones that moved and trained under his command. The week of leisure had ended, and it was time to resume the relentless pursuit of mastery.
Power is never stagnant. Every technique, every chakra flow, every seal can be refined… improved… weaponized, he thought, pacing across the lab.

Kirito knelt on the lab floor, concentrating. He stretched his fingers and focused his lightning chakra, channeling it into a single point in his palm.
"Electricity… intensity… speed… concentration," he muttered.
A small spark flickered, then surged violently. His first attempt at Chidori was crude—unstable, almost burning his hand.
Patience. Focus. Flow. The chakra core can handle it, he reminded himself, feeling the steady pulse of the core beneath his chest.
Hour by hour, he refined the technique. Clones mirrored his practice, each focusing on stabilizing the lightning chakra, controlling its destructive potential, and learning to move at incredible speed while maintaining precise focus.

Once the basic Chidori was stable, Kirito began experimenting with variants, inspired by Sasuke's techniques in canon but improving them with his own creativity:
Fire-Infused Chidori: Combining his fire affinity to increase destructive power and create elemental explosions on impact.
Wind-Enhanced Chidori: Infusing wind chakra to extend reach and increase penetration speed.
Vanishing Chidori: Using his stealth and teleportation marks to appear instantly behind a target before unleashing the attack.
Multi-Point Chidori: Coordinating clones to strike simultaneously from multiple directions, overwhelming defenses.
Each variant required precise chakra control and perfect clone coordination, a challenge even for his amplified chakra reserves.

Forbidden Jutsus and Explosives
While his clones practiced Chidori, Kirito turned his attention to other forbidden jutsus he had obtained from the Hokage building and his previous research:
Mutually Multiplying Explosive Tags: He experimented with combining multiple explosive tags, creating chain reactions that could devastate large areas without endangering his clones.
Sealing Jutsus: Reinforcing barriers and experimenting with elemental-infused seals, he combined his fuinjutsu mastery with his clones' precision, crafting seals that could trap, amplify, or suppress chakra.
Rushroom Summoning: Training clones to summon and control the massive mushroom-shaped constructs for both defense and attack.
Five Elemental Seals: Practicing sequential elemental seals, combining fire, water, wind, earth, and lightning into a synchronized defensive-offensive array.
He spent hours analyzing the interactions between chakra types, elemental fusion, and sealing techniques, integrating them into a single operational system that his clones could execute flawlessly.

Clone-Assisted Research
Kirito sent multiple clones across the lab to perform parallel experiments:
Clone One practiced chaining explosive tags with perfect timing, analyzing the energy feedback.
Clone Two combined elemental seals with offensive jutsus to see how barriers could enhance attacks.
Clone Three experimented with summoning techniques, ensuring stability and rapid deployment.
Kirito mentally monitored every clone, making adjustments and recording outcomes for refinement.
Each clone is a laboratory. Each experiment is a step closer to perfection, he thought, noting every improvement.

Integration Into Combat
By the end of the day, Kirito began testing integration:
Multi Shadow Clones executed synchronized Chidori strikes from multiple angles.
Flying Thunder God marks allowed instant positioning behind targets.
Elemental seals reinforced the battlefield, amplifying attacks and restricting enemy movements.
Explosive tags detonated in precise patterns, coordinated with clone attacks.
The lab was filled with the hum of thousands of chakra flows, sparks of lightning, bursts of fire, and the faint hiss of seals activating. Each movement was calculated, controlled, and devastatingly efficient.
Kirito watched silently, hands resting on his chakra core. This is no longer practice. This is my army, my offensive, and my shield. Every jutsu, every forbidden technique, every elemental seal—mastered and ready.

Inner Reflection
Sitting cross-legged, he allowed himself a moment of thought:
Two months for clones and forbidden jutsus. Weeks of Chidori experimentation. My army, my marks, my seals… everything is integrated. Nothing will stop me—not in the village, not outside. My power is absolute, and my preparation is perfect.
He formed a small circle in front of him and silently sent instructions to every clone: continue practicing independently, continue integrating the techniques, and begin preparing for field applications.
Tomorrow, he thought, I will begin combining these jutsus in real combat scenarios. Chidori, explosive tags, sealing jutsus, summons, and clones… everything working as one. My army will be unstoppable.
The hum of his chakra core echoed through the lab, the shadows of hundreds of clones moving silently in perfect synchronization—a testament to the power of preparation, discipline, and absolute control.
