Once this thought arose, it spread wildly through Hiroki's heart like a prairie fire. By studying the scattered legacy left by Tsukabishi Tessai, combining it with the analytical power of his SSS-rank Kido talent, and then integrating the collaborative concepts of Combined Ninjutsu from the Naruto World, he would create a unique "Combined Kidō" system exclusive to his own forces!
The value of this project far exceeded the sum of all other current technologies in the Kidō Corps! It could become an ultimate trump card capable of deterring the entire Three Worlds and even potential unknown enemies!To think was to act! Hiroki had always been a man of action, loathing empty talk and procrastination most of all.
The immense temptation and strong desire for exploration overrode everything else.He made his decision without hesitation: seclusion!He immediately turned around, walked out of the technical room, and found Uchiha Izumi, who was methodically arranging the new personnel structure.
"Izumi,"
Hiroki's voice carried an unquestionable decisiveness,
"I need to start an important research project immediately. You will be responsible for all daily affairs, personnel management, and resource allocation within and outside the Kidō Corps. Do not disturb me unless it's something extremely significant."
He didn't reveal the specific details, but Izumi immediately grasped the weight of this "important research" from his eyes and tone.She didn't ask any questions, simply nodding firmly:
"Yes, Hiroki-sama. Everything here is under my care; please rest assured."
Having finished his instructions, Hiroki no longer hesitated.He chose a Meditation Room next to the Technical Archives Room, specifically reserved for the Grand Kido Master, which possessed a powerful Barrier for soundproofing and reishi isolation.
The heavy stone door slowly closed behind him, isolating him from all the noise and light of the outside world.He sat cross-legged, the space before him piled high with all the materials related to combined-type Kido he'd brought from the technical room, along with his own drafts conceived based on Kido principles and the concept of Naruto's Combined Ninjutsu.Time passed quietly amidst absolute silence and a mental storm of high concentration.
Hiroki's brain operated frantically, like the most precise supercomputer.His SSS-rank Kido talent allowed him to easily see through the essence of every basic incantation and grasp the patterns of every strand of reishi flow.He first attempted to understand the scattered models left by Tsukabishi Tessai, visualizing those abstract symbols and energy flow lines in his mind to simulate their operation.
When encountering difficulties that Tessai had failed to solve, he drew upon experiences from the Naruto World—such as coordinating the Chakra Meridian System, merging Chakra Nature Transformations, and the energy synergy required when using Shadow Clones or Summoning Beasts to perform large-scale Ninjutsu (though he wasn't an expert in those fields, the principles were similar)—to conduct bold analogies, deductions, and modifications.
He repeatedly designed and deduced the positions of energy convergence "nodes," the structure of Spiritual Pressure transmission "channels," the "frequency" resonance points for incantation synchronization, and the "pressure relief valve" mechanisms for dispersing recoil... Countless plans were constructed, collided, shattered, and reorganized within his conscious space.
Innumerable complex formations, outlined by pure mental power, flickered in and out of existence in the air above the floor before him.Sweat soaked his robes, only to be evaporated by the Spiritual Pressure leaking from his body.The mental exhaustion far exceeded physical fatigue.At times, his brow would be locked in a frown as he spent days contemplating a certain point of energy intersection;At other times, he would suddenly grow excited, grabbing a pen to rapidly write down a flash of inspiration on a specialized reishi-sensing scroll.
The problems he needed to solve were piled high like a mountain: How could he make the Spiritual Pressure fluctuations of dozens of different individuals reach a high degree of consistency in an instant?How could he avoid internal implosions caused by minute differences during the process of converging massive amounts of energy?How could he design a core technique that could both withstand that terrifying torrent of energy and release it efficiently and directionally? How could he protect the practitioners from being torn apart by the backlash generated by the combined technique?Behind every question lay profound knowledge of Kido-logy, Reishi Dynamics, Barrier formations, and even Soul Energy Studies.
During this near-masochistic deep seclusion, the only times Hiroki contacted the outside world were when he occasionally used his phone to reach Izumi, concisely requesting specific internal data on the individual Spiritual Pressure characteristics of Kidō Corps members or test samples of certain rare reishi materials.
Izumi always satisfied his needs quickly and perfectly, while also ensuring that no trivial matters disturbed him in the slightest.Under her management, the Kidō Corps gradually shed its former lethargy and began to resume normal training and Barrier maintenance work. The members' hearts were filled with awe and anticipation for the new Grand Kido Master's mysterious research.
As the days went by, the only sounds in the Meditation Room were the rustling of pen on paper, the faint glow of reishi scrolls being activated, and Hiroki's own low, rapid voice simulating incantations.Finally, late one night nearly a month after Hiroki had entered the Meditation Room, the continuous reishi fluctuations and the faint lights of various deductions within the room suddenly subsided.Hiroki let out a long sigh of relief, as if exhaling all the fatigue and mental burden accumulated over the past month.His eyes were bloodshot from long-term lack of sleep and high-intensity thinking, but an excited and fanatical flame burned deep within his pupils.
Spread out on the giant scroll before him were no longer scattered drafts and broken models, but instead a relatively complete, logically rigorous, and clearly structured preliminary implementation plan for the Combined Kidō technique!Although this was merely the completion of the theoretical framework and basic model construction—with a long road ahead before actual combat use, many details requiring repeated verification and polishing, and the crucial combat stability and power limits still unknown—the most important first step of turning that wild idea from paper into a feasible technical roadmap had been successfully taken!
Hiroki carefully put away the scroll that condensed a month of his hard work, feeling the cool touch of the paper and ink against his fingertips.He stood up and stretched his stiff limbs from sitting for so long, his bones letting out a faint popping sound.An unprecedented sense of fatigue washed over him like a tide, but it was surpassed by a massive sense of satisfaction and an impatient urge to verify his work.
"Preliminary plan completed..."
he whispered to himself, pushing open the closed stone door of the Meditation Room.The corridor outside remained absolutely quiet, with only the dim reishi lamps on the walls emitting a soft glow.
But he knew that Uchiha Izumi must be somewhere nearby handling affairs, keeping a constant watch for movement here."Now, it's time for the testing phase."Regarding the personnel to participate in this significant, pioneering, and even dangerous preliminary test, Hiroki already had a clear target in mind—the members of the Kidō Corps.The reasons were quite simple:They were right there at the headquarters, available at a moment's notice, saving the trouble of transferring people from other divisions and the potential attention that might attract.
They were also full-time Kido practitioners; their understanding of basic Kido techniques, incantation chanting, and Spiritual Pressure control far exceeded that of ordinary Shinigami members.This perfectly matched the requirements of Combined Kidō for individual basic skills.In Hiroki's view, although these members had been "slacking off" before, the fact that they could enter the Kidō Corps meant their inherent talent and foundation weren't bad.
What they needed was a direction, an opportunity to prove themselves.This test was both a verification of the technology and a way to gauge and re-stimulate their abilities.Conducting the test inside the Kidō Corps headquarters offered relatively higher confidentiality and security.
With Izumi holding the fort and Hiroki supervising personally, the risk range of the test could be effectively controlled.Most importantly, even if something happened to these people, Hiroki wouldn't feel any heartache.Hiroki strolled through the empty corridors, his footsteps echoing in the quiet space.He turned his gaze toward the brightly lit training grounds and dojos, as if he could already see the expressions of the members—a mixture of nervousness, excitement, and curiosity—once they were summoned.
He needed their strength, their experience, and their reactions to verify whether the seed named "Combined Kidō" could truly break through the soil he had carefully constructed and eventually grow into a towering tree that would shake the foundations of the world.The curtain for the test was about to officially rise in the long-silent Kidō Corps headquarters.
