Naruto's civilian cannon fodder starts with the three-body technique

Chapter 297 Soul Chip (Bonus Chapter, 10,000 words per day)
呲味味~
The chaotic and unruly violent energy emanating from the regeneration core, as if finding an outlet, surged wildly into Samehada's mouth.

Samehada's body trembled violently, and chaotic streams of chakra overflowed from between its scales.

At this moment, Umino Sasuke quickly took out several specially made, highly concentrated secret medicines and swallowed them. The medicinal power instantly dissolved in his stomach, turning into a rolling hot current. He immediately activated the Gluttony Technique, and his powerful digestive ability converted all the medicinal power into pure food energy.

"Samehada!" Umino Sasuke shouted, channeling the immense and delicious energy of the food into Samehada's body.

Samehada, who was suffering from the violent energy of the regeneration core, felt the familiar and delicious warm current flowing into it, and like a long-awaited rain after a drought, it made a series of satisfied gurgling sounds.

The food energy was quickly digested by it, which not only relieved the pressure brought by the raging chakra of the regeneration core, but also greatly improved its efficiency in absorbing and converting energy.

The mixed energy it devoured underwent a peculiar biological transformation within its body, where its violent and chaotic attributes were quickly removed, transforming into relatively gentle and pure chakra. This newly generated chakra was not stored by it, but rather, like a feeding back, it was continuously transported back into Umino Sasuke's body!

hum~
Sasuke Umino was greatly encouraged.

This influx of chakra, like sweet spring water flowing into a dried-up riverbed, quickly replenished his chakra reserves.

Having received a chakra replenishment, he immediately mobilized the Ice Release bloodline chakra within his body and continued to inject it into the nascent chakra core in his palm, refining it continuously.

Thus, a remarkable triangular cycle is formed:
Initially, Umino Sasuke infused Ice Release Kekkei Chakra into the outer chakra core.

Subsequently, the chakra core was stimulated by the Ice Release bloodline chakra, causing the Hashirama cells and Nine-Tails chakra within it to proliferate continuously, releasing a chaotic and violent energy.

Afterwards, Samehada absorbs this dissipated energy and uses the energy from the food provided by Umino Sasuke as the driving force for the entire cycle, converting it into pure chakra and feeding it back to Umino Sasuke.

Finally, Umino Sasuke was replenished and continued to infuse Ice Release Kekkei Chakra, constantly refining the outer chakra core.

Although this cycle is slow, it is exceptionally stable. Umino Sasuke no longer needs to worry about running out of chakra; he only needs to continuously provide food energy as the power source for Samehada, the "converter."

And in this continuous refining process, astonishing changes are quietly taking place in all three parties:

Regarding the chakra core, the icy blue light is becoming increasingly deep and dominant. The emerald green veins inside are becoming more gentle and orderly. The scarlet Nine-Tails chakra is also being continuously compressed and assimilated. The violent aura is gradually weakening and becoming more restrained and pure. It is slowly being imprinted by Umino Sasuke's Ice Release bloodline chakra, gradually evolving towards a true "outer core".

As for Sasuke Umino, during the continuous refinement of the chakra core, the chakra within his body was as if it had been repeatedly tempered. The pure chakra that was fed back through Samehada inevitably became tainted with a trace of the refined Yin-Yang chakra of the Nine-Tails, as well as the life force of Hashirama's cells.

Although extremely weak, over time, the nature of his chakra is indeed undergoing a subtle transformation, becoming purer, more resilient, and containing a strange quality that combines vitality and ferocity.

The upper limit of the total amount of chakra is also showing signs of loosening in this cycle of output and replenishment. The total amount may not have much effect yet, but the quality has an immediate effect.

As for Samehada, as the center of energy conversion, it naturally benefits the most.

In this continuous process of absorption and transformation, the high-level Nine-Tails Yin-Yang Release chakra and the abundant life force of Hashirama cells, along with the pure food energy provided by Umino Sasuke, absorbed and transformed these three energies. Samehada's body was expanding at a visible speed, its scales became thicker and tougher, shimmering with a metallic luster, its sharp teeth became more ferocious, and even its forehead had faint keratinous protrusions.

The chakra fluctuations it emitted were rising steadily, already surpassing the scope of ordinary summoning beasts, showing the potential to grow into a tailed beast-level summoning beast.

However, Samehada is not a tailed beast after all, and its absorption and conversion have an upper limit. Even with an endless supply of food energy as its driving force, it has reached its limit. Umino Sasuke could only reluctantly withdraw from this unconventional dual cultivation and pause the output of his Ice Release bloodline chakra.

Slowly opening his eyes, the nascent chakra core in his palm now radiated a more restrained, icy blue light. The conflict between the emerald green and scarlet was greatly reduced, and the overall energy exuded a more stable and profound aura.

Although we are still far from complete refining, the first step of "taming" and the energy cycle framework have been successfully established.

He carefully put away the smaller but more refined "outer core" with satisfaction. Samehada also let out a satisfied burp, his body had grown a whole size larger, and his aura was frighteningly strong.

"It seems I'll have to set aside half an hour every day to practice this unconventional dual cultivation method from now on."

Sasuke Umino stroked Samehada, which was becoming increasingly hard yet more vibrant. He already had a training plan in mind. He had to push Samehada to its limits. Even if it wasn't for refining the chakra core or purifying his own chakra, he had to cultivate Samehada. If Samehada could truly complete its transformation, even if it didn't become a tailed beast-level summoning beast, at the very least, it would be a powerful ally even at the Kage level.

Moreover, under the assimilation of the Nine-Tails' chakra, not to mention growing stronger, the fact that it can not be afraid of and even devour fire-style ninjutsu is a significant improvement.

Umino Sasuke patted Samehada, whose size had increased dramatically and whose aura was now powerful, in a reassuring manner. He knew the enormous potential of this "triangular dual cultivation" method and decided to include it in his daily training.

Just as he finished his first daily dual cultivation practice, the four shadow clones responsible for debugging finally completed their work and reported to him: "Lazy main body, the energy cores of the four mecha puppets have been successfully adapted, the Hashirama cell regeneration cores are operating stably, and the chakra shield system has been successfully activated..."

Sasuke Umino nodded and immediately released a shadow clone to receive its memories and experiences.

In the mental image, four steel behemoths, controlled by shadow clones, moved at high speed and engaged in low-powered firefights in the underground test field. The emerald green chakra shields flowed across the surface of the mecha puppets like living things, their agility and smoothness far surpassing the chakra shields that relied on the berserk energy storage engine to drive them before!

"The active chakra provided by the Hashirama cell regeneration nucleus is indeed extraordinary!"

Sasuke Umino's eyes gleamed. He could clearly see that, with the same energy output, the defensive strength of the Regenerating Core Shield had increased by at least 60%, while the energy consumption had decreased by nearly half.

Moreover, when the activated chakra shield is not subjected to energy impact, most of its energy can be recycled and reused. Compared to the energy storage engine, the actual energy loss is reduced by more than ten times.

The energy stored in these engines, originally intended to maintain the chakra shield, can be saved and channeled entirely into the chakra cannons in the shoulders and arms, increasing their power and significantly enhancing the power and range of the cannon fire.

"The energy storage engine is now only responsible for providing burst output for the weapon system, and the energy utilization rate is indeed higher."

Sasuke Umino was very satisfied with the result. He waved his hand and dismissed the remaining three shadow clones. The light on the chests of the three mecha puppets dimmed, and they stood silently like sleeping giants.

"The control of shadow clones is ultimately a significant weakness. Once the clones are destroyed or dispelled, the puppet will immediately become paralyzed. This is especially fatal when facing a truly powerful opponent!"

Looking at these four steel creations equipped with Hashirama cell regeneration cores and whose combat power had soared, Sasuke Unno frowned slightly.

"Intelligent puppets?!"

This thought became incredibly strong again. He walked to one of the mechs, stroked the cold metal shell, and felt the steady, pulsating flow of life energy inside.

"We've already achieved the goal of making human puppets intelligent. With the technical support of Orochimaru and Hiruko, the challenge of making mechanical puppets intelligent might not be insurmountable!"

Sasuke Umino muttered to himself, his thoughts returning to the unexpected success of the glass mechanical puppet.

The initial sealing of the glazed jade, preserving its soul, was merely a cautious and casual act; unexpectedly, it yielded a great reward.

He discovered that the blank soul of the glass mechanical princess puppet, whose memories had been wiped away, was actually more useful than an intelligent chip. This "soul chip," after being programmed with instructions using the Spirit Transformation Technique, exhibited an amazing learning ability, especially for the ninjutsu it had mastered in its previous life. It had an almost instinctive muscle memory for these techniques, far surpassing the mechanical intelligence it had obtained from Orochimaru and Hiruko.

"If we could apply this 'soul chip' to mecha puppets..."

Sasuke Umino calmly analyzed the situation with sharp eyes, "There are two technical bottlenecks. First, how to embed the 'soul chip' into the non-physical metal energy center and establish a stable mental link with the puppet's chakra circuits. This requires soul binding and energy channel construction technology that far surpasses the current human puppet technology. It seems that only the most advanced sealing techniques can achieve this."

He walked to the workbench, picked up a scroll containing sealing techniques he had obtained from Iwagakure, but shook his head. There weren't many advanced sealing techniques recorded inside, and the sealing techniques for tailed beasts could only be used as a reference and couldn't solve this technical problem.

"However, the second issue, energy compatibility, has been easily resolved."

A smile finally appeared on Umino Sasuke's face. The energy storage engine system he obtained from the Sky Ninja provided violent and disordered chakra that lacked activity. This disorder in energy was like fine sand mixed into the chakra stream, which would quickly wear down, erode, and even destroy the fragile "soul chip," causing it to become disordered and collapse.
