Silent Exchange and Learning

At dusk in the Hidden Sand Village, the windblown sand was tinged with a warm golden hue. Shaye's slight figure passed through the gradually quieting streets, skillfully turning onto the path leading to the secluded temple.

Inside the temple, an oil lamp flickered like a bean. Monk Bunpuku still sat on his plain cushion. When he saw Shaye enter, a gentle smile appeared on his wrinkled face. "You're here."

"Master." Shaye nodded softly and sat on the cushion opposite him, though his gaze could not help drifting toward the complex sealing formula on the old monk's abdomen. He could "feel" that the big fellow seemed rather restless today.

[Hmph! Brat, you're here to disturb my peace again!] A sharp, hoarse voice rang directly in his mind, carrying a trace of impatience. It was Shukaku.

Shaye answered silently, [Don't you complain about being bored all day? I came to keep you company, and you still dislike it?]

[Pah! Who wants your company? I am the noble One-Tail, not some little runt's playmate!] Shukaku retorted angrily, but Shaye could sense that there was no genuine malice in that consciousness. Instead, it carried a hint of... expectant denial.

"Shaye," Bunpuku said slowly, interrupting the silent exchange between the boy and the beast, "today, we will study the foundational rune structure of the Four Symbols Seal. It involves an exquisite balance between space and energy..."

The old monk dipped his finger in water and traced intricate lines across the stone floor. Shaye immediately composed himself and watched with utmost focus. His mental strength, far beyond that of children his age, allowed him to clearly remember every turn of the runes and every implied flow of chakra.

[Tch, the Four Symbols Seal? Such crude stuff!] Shukaku scoffed in his mind again. [I've seen more ancient seals than you've eaten grains of rice! Those Adamantine Sealing Chains that can draw upon natural energy, now those are—] It abruptly stopped halfway through, apparently realizing it had said too much.

Shaye's heart stirred. "Natural energy"? The term reminded him of some vague concepts he had encountered in his previous life. He did not press further, merely engraving the phrase deep into his memory. He knew he could not rush when prying information out of this tsundere tanuki.

By the time he left the temple, night had fallen deep. Shaye's mind held not only the beginnings of the Four Symbols Seal, but also several older, more obscure barrier runes that Shukaku had "accidentally" revealed.

He did not return home directly. Instead, he headed toward Elder Chiyo's house. Today was the day he had been permitted to borrow medical ninjutsu scrolls.

The one who opened the door, however, was Sasori of the Red Sand. Young Sasori's expression remained indifferent. Upon seeing Shaye, he merely shifted slightly to let him inside.

"Grandmother Chiyo went to an elders' meeting." Sasori's voice was flat. "The medical scrolls are in the study. Find them yourself."

"Thank you, Senior Sasori." Shaye thanked him politely, but his eyes were drawn uncontrollably to an unfinished puppet arm on the workbench. Its internal structure was extraordinarily ingenious. Gears and chakra-conducting metal wires were combined in ways he had never imagined, carrying a strange kind of beauty.

Sasori noticed his gaze and, unusually, asked another question. "Can you understand it?"

Shaye took a deep breath, suppressing his excitement as he pointed at several crucial joints. "Here... you used elastic metal plates instead of rigid connections to cushion the impact, right? And this conduction circuit seems to bypass the usual nodes. Is that to reduce chakra loss?"

A faint flicker of surprise passed through Sasori's eyes. He had not expected this frail-looking brat to possess such sharp insight into puppet construction. Rather than answering, he picked up a tool and adjusted the angle of a tiny gear on the puppet arm. Then he said coldly, "A standard circuit has a 0.3-second delay. Change it like this, and it can be reduced to 0.1 seconds. The gap between life and death often lies in those 0.2 seconds."

Those words struck Shaye like lightning. He stared blankly at the tiny alteration as concepts from mechanical design in his previous life—"optimization," "efficiency"—perfectly overlapped with the "precision" and "lethality" of Puppet Technique.

After finding the medical scrolls that recorded the Healing Technique and basic knowledge of the human meridian system, he practically floated away.

Back home, lying on his crude bed, Shaye's mind was still racing. The grandeur and precision of sealing techniques, the ingenuity and lethality of Puppet Technique, medical ninjutsu's exploration of life energy, and the wild idea in his home regarding Magnet Release, which combined the material foundation of earth with the energy form of wind...

These seemingly unrelated branches of knowledge began to sketch out faint yet wondrous connections through the perspective of his soul from another world.

"The body is the foundation, the source of energy... Chakra is a tool, the driving power... Puppets are extensions, vessels for function... And sealing techniques and barriers are the programs that control and restrain energy..."

He raised his still slender, powerless-looking hand and clenched it loosely in the darkness.

"If... if I could make a 'furnace,' with sealing techniques and barriers forming the core program, puppet technology forging the shell and energy circuits, and medical ninjutsu knowledge guiding the energy to 'repair' and 'strengthen' this body..."

A concept so vague it was nearly impossible to grasp, yet one that made his heart race wildly, surfaced quietly in the depths of his mind for the first time, like a mirage in a sea of sand.

The night was still long, and on this night, many puzzle pieces were destined to begin seeking the places where they fit together in the heart of this transmigrator.
