The night air was crisp as Kirito moved silently across Konoha's rooftops. The shadows clung to him like a second skin, his movement so precise it was as if he were a whisper carried on the wind. The stolen knowledge—scrolls, notes, and every forbidden jutsu he had recorded in the Hokage building—was safely stored in an unassuming satchel beneath his cloak. Not a single trace of his presence remained behind; the faintest inkling of disturbance had already been erased by the masterful fuinjutsu seals he had inscribed along the walls and floor.
Everything is accounted for. Every jutsu, every forbidden technique… and every secret scroll. Now, the real work begins, he thought, his mind already racing ahead.
Sliding through the shadows, he arrived at the Forest of Death, where his hidden laboratory waited, concealed under layers of fuinjutsu and natural camouflage. The entrance shimmered briefly as Kirito performed a series of complex sealing hand signs, dissolving the barrier long enough to slip inside. Once inside, the lab was quiet, sterile, yet brimming with latent energy. Hundreds of vials, jars, and scrolls lined the shelves, each containing knowledge or experimental material he had accumulated over years of clandestine missions.
He exhaled slowly. "Time to awaken the apprentices," he muttered.

Activating the Clones
Kirito created twenty shadow clones in rapid succession, each perfectly identical, each capable of independent thought within his parameters. They bowed slightly, as if acknowledging their purpose.
"You all know your tasks," Kirito said quietly, pacing the lab. "We will begin training immediately. Priority one: Flying Thunder God Jutsu. Priority two: Multi Shadow Clone Jutsu. These two will define our mobility and combat dominance. I want every clone to understand and replicate the techniques perfectly. No mistakes."
The clones nodded in unison, their chakra flowing outward as they activated their training modules. In one corner, a clone began practicing the complex hand seals for Flying Thunder God, the precise motion of each finger a delicate dance of chakra control. In another, a clone practiced the synchronization and energy management required to create multiple shadow clones, each clone working to replicate Kirito's twentyfold chakra amplification within its own form.
Kirito observed silently, his mind analyzing every motion, every flow of chakra, every subtle misalignment. He corrected their postures, adjusted their chakra flow, and occasionally whispered a modification to improve efficiency.
"Focus," he said, watching one clone falter mid-hand seal. "Your chakra is not just energy; it's a medium. Your mind controls it, not the other way around. Flow it, do not force it."

Flying Thunder God: Precision and Mastery
Hours passed as the clones trained. Kirito created a small, glowing mark on the floor and instructed one clone to teleport to it using the Flying Thunder God Jutsu. The clone disappeared and reappeared instantly, its body perfectly stable, chakra flow uninterrupted.
"Excellent," Kirito said, a rare hint of approval in his voice. "Now do it repeatedly. Precision is more important than speed. Speed without precision is death in combat."
He walked between clones, observing as each practiced, adjusting subtle flaws, reinforcing their understanding of instantaneous movement. His own chakra core thrummed in tandem, feeding each clone with supplementary energy, ensuring that every student could reach near-perfect execution without exhausting their reserves.

Multi Shadow Clone Jutsu: Efficiency and Control
After Flying Thunder God, Kirito turned his focus to Multi Shadow Clone Jutsu. He demonstrated first, forming fifty clones in a heartbeat, each one immediately performing its designated task, from elemental attacks to reconnaissance exercises.
"You see this?" he said. "Control is everything. Too many clones without proper chakra management will collapse your body and leave you vulnerable. I want each of you to create at least a hundred clones simultaneously. Maintain them. Perfect them. Your consciousness must be distributed without losing clarity."
The clones trained tirelessly, replicating his demonstration, sometimes failing, sometimes succeeding. Each failure was an opportunity for analysis; each success was a milestone toward domination of the technique.
Kirito took meticulous notes in his own mind, mentally recording which clones could maintain stability for extended durations, which required additional chakra flow adjustments, and how the core could enhance their durability.
Flying Thunder God and Multi Shadow Clone… once mastered, I will be untouchable in both mobility and numbers. A single misstep in battle will be fatal for anyone who opposes us, he thought.

Integration of Forbidden Jutsus
Once the clones had reached intermediate mastery of the two priority techniques, Kirito introduced them to the forbidden jutsus he had acquired from the Hokage building. Each scroll was carefully sealed and annotated, with fuinjutsu marks ensuring that only the intended clone could access the information.
"Study them," he instructed. "Do not rush. Each technique has consequences if performed incorrectly. Flying Thunder God and Multi Shadow Clone are your foundation. These forbidden jutsus will be your weapons, your tools for domination. Learn them well, and respect them."
He watched as the clones carefully began to replicate the seals, hand signs, and chakra flows required for the forbidden techniques, making minor adjustments to ensure each clone could execute them safely. Some techniques were too complex to perform immediately, but Kirito's networked mind allowed him to guide each clone subtly, ensuring that they absorbed the knowledge efficiently.

Strategic Planning
As night deepened, Kirito moved to the central console of the lab. He projected the chakra flows of every clone onto a mental map of Konoha, marking potential escape routes, infiltration points, and surveillance areas.
Flying Thunder God for rapid strikes, Multi Shadow Clone for reconnaissance and diversion, forbidden jutsus as decisive strikes… With twentyfold chakra, I can maintain this indefinitely. The village cannot hope to track me or my operations.
He paused, closing his eyes. "I must remain patient. Every clone must be perfect. Every technique must be flawless. Only then will the real tests begin."

End of the First Training Night
By dawn, the clones had pushed through several cycles of practice. Flying Thunder God and Multi Shadow Clone were improving exponentially, their execution cleaner, faster, and more precise with each repetition.
Kirito, still physically present but mentally projecting through dozens of clones simultaneously, allowed himself a small nod of satisfaction. We begin the next stage tomorrow… integration with forbidden techniques, elemental jutsus, and fuinjutsu. This is only the beginning.
The laboratory, now filled with the soft hum of chakra and the quiet movements of dozens of clones, was alive with the energy of disciplined learning. And at the center of it all, Kirito's twentyfold chakra core pulsed steadily, the heart of a growing empire of power.
