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

Chapter 439 Absorbing the Kaleidoscope

Sasuke Unno did not directly refute, but he knew very well that it was not impossible to win with four thousand against ten thousand, but it would be much more difficult to reduce casualties unless he stopped pretending to be injured and went all out.

But if we do that, all our previous efforts will be wasted, and how will we be able to trick Hiruzen Sarutobi in the future?
It seemed that to prevent the Konoha ninja clan from gaining merit while minimizing our casualties, we needed to find a way to achieve both. His mind raced, and he finally made a decision. Without further hesitation, he began issuing orders:
"Order! All units to rest and regroup, scouts to expand their reconnaissance range, and closely monitor the movements of Iwagakure. We must seize the opportunity and crush the Iwagakure army before Akimichi Torifu and his men arrive!"

"Yes!" Danzo, Tsukiko Yoru, Aburame Ryoma, and the others answered in unison.

After giving the order, Sasuke Umino vanished from the tent in a flash, using the Flying Thunder God Technique.

The next moment, they appeared in the underground laboratory of the Land of Waves.

Inside the laboratory, the lights were on, and various precision instruments emitted a low hum.

"It's reasonable that a 'disabled ninja' with a specially designed mechanical prosthetic limb could 'rise up with his remaining strength' at a critical moment and fight to the death for Konoha, right?"

Sasuke Umino walked to the central workbench, his gaze falling on the advanced mechanical prosthetics made of chakra alloy and biological tissue.

"A Jonin-level mechanical prosthetic is a powerful tool for the Iron Wall Anbu, but it's still too weak to withstand the full power of a Wood Release clone," Umino Sasuke muttered to himself.

He has been researching mechanical prosthetics for a long time and has made quite good progress. Especially after obtaining the puppet technology of Sunagakure and Hashirama's cell samples, he has surpassed Sunagakure in the field of biomechanics. Changing a puppet arm like Chiyo is no longer difficult for him.

Of course, technological bottlenecks still exist.

Although he can now create high-performance Jonin-level prosthetics, he still needs to accumulate experience to reach the level of a perfect Hashirama cell prosthetic like Naruto's in later generations.

Inside the laboratory, there was no shortage of prosthetic materials, and he had extremely rich manufacturing experience. The prosthetics of the Jonin captains of the Iron Wall Anbu were all made by him personally.

The Iron Wall Anbu was able to expand so rapidly largely because of this; many elite ninjas who were unwilling to return to their villages to retire chose to die "unnaturally," went underground, and became members of the Iron Wall Anbu.

They didn't replace them with defective products from Sha Chongba and other leaders of the Jingsha New Army, but rather with high-quality products tailored specifically for them!

Equipped with these specially made prosthetics, these ninjas not only regained their strength but also gained additional abilities. Those who switched hands could form hand seals at a speed of at least three per second; those who switched legs could maximize their taijutsu and teleportation abilities; and those who switched eyes gained enhanced perception and added functions such as thermal imaging.

This is why many members of the Iron Wall Dark Division who are physically healthy often request to undergo "optimization" surgery to replace their limbs with prosthetic parts with specific functions in order to enhance their strength. This unique "technical benefit" is one of the important reasons why the Iron Wall Dark Division has such strong cohesion and combat power.

"However, this level of prosthetic limb is still not enough!"

Each of his Wood Release clones possesses combat power comparable to that of an elite Jonin. Simply installing these Jonin-level prosthetics would undoubtedly weaken his abilities.

He was already very skilled at creating Jonin-level prosthetics, but it would be difficult to break through to the next level. Naruto Uzumaki's Hashirama cell prosthetics were a good direction.

Unfortunately, the corrosiveness of Hashirama cells is too strong, or perhaps due to insufficient technological accumulation. The Hashirama cell prosthetics he creates are fine for his own use, but if given to other members of the Iron Wall Dark Division, they would be scrapped after only a few days. Literally, both the prosthetic and the host would be rendered useless.

After repeated attempts, the snake venom in Ryūchi Cave had a certain inhibitory effect, but it still could not solve the fundamental problem.

"It needs to maintain activity, be compatible, and also inhibit the invasiveness of intercolumnar cells..."

Sasuke Umino fell into deep thought, his fingers tapping unconsciously on the workbench. Finally, a glint of light flashed in his eyes. "What if we replaced the chakra alloy frame with a more active branch of the Divine Tree?!"

Thinking of this, his eyes lit up, and without further hesitation, he formed a hand seal, and his figure vanished instantly.

The next moment, they appeared in the underground dragon vein cave of the Loulan Kingdom.

Before our eyes, the sacred tree of the mountain village, rooted in the dragon vein, has grown to more than ten meters tall, with lush branches and leaves, radiating a shimmering glow, and nine unripe sacred tree fruits hanging on the tree.

Despite having harvested several batches already, he was still very excited to see the Divine Tree Fruit again. There was no way around it; the effects of the Divine Tree Fruit were simply too good, especially in improving a ninja's aptitude and potential.

Even though he had consumed a large amount of fruit and developed some drug resistance, he could still feel his body undergoing a subtle but positive evolution with continued use.

If he continues to take it without interruption, even if he does nothing, he could probably grow to the level of the Sage of Six Paths in less than a hundred years, or even approach the level of Kaguya Otsutsuki.

Calming his mind, Umino Sasuke drew the Thunder God Sword, and azure lightning instantly enveloped the blade.

"Purple Lightning Slash!"

He swung his sword at a rather crowded branch, and with a soft "whoosh," a small section of the divine tree branch, shimmering with a metallic sheen, fell to the ground.

Even if it's a counterfeit divine tree, its hardness is astonishing, no less than that of chakra alloy.

Sasuke Umino carefully put the branch away, used the Flying Thunder God Technique once again, and returned to the laboratory in the Land of Waves to continue his experiments on prosthetic limb manufacturing.

This time, he abandoned traditional chakra metal and meticulously sculpted the skeletal framework of the prosthetic legs using the branches of the Divine Tree as the core. The branches of the Divine Tree far surpass chakra metal in hardness and toughness, and also contain a strange life force.

When he combined the cultivated Hashirama cell tissue with the branches and bones of the Divine Tree, the effect was surprisingly good. The Divine Tree seemed like a gentle mother, perfectly accepting the Hashirama cells. Its own peaceful and enormous life energy effectively neutralized the violent corrosive properties of the Hashirama cells.

A mysterious resonance and balance was achieved between the two!
"We did it!" Sasuke Umino's eyes shone with joy.

After tireless debugging and integration, he finally created the first Hashirama cell prosthetic that could operate stably and had an energy conduction efficiency far exceeding that of the previous ones. Moreover, ordinary Iron Wall Anbu ninjas could also use it.

After completing the task, Sasuke Umino quickly formed hand seals and created a Wood Release clone with missing legs.

"Number Nine, initiate the Wood Release technique."

Sasuke Umino installed the brand-new prosthetics on the severed legs of his Wood Release clone, Number Nine.

The connection process went exceptionally smoothly. The Hashirama cells at the interface of the prosthetic limb fused perfectly with the Wood Release body of the clone, and the nerve connections and chakra channels were instantly established. The Wood Release clone No. 9 sensed his new "legs," and his eyes immediately shone with astonishing brilliance. He moved his ankles and performed several difficult taijutsu moves with incredible fluidity.

"Unbelievable! As expected of Hashirama cells, the activity and chakra affinity are incredible! Main body, even after consuming so many fruits from the Divine Tree, your current level of Sage Body development is still far behind that of Hashirama Senju," the ninth clone exclaimed.

"Number Nine, Hashirama Senju is the reincarnation of Ashura, so it's normal that I'm not as good as him for now, okay? Besides, my Wood Release was only recently awakened, and my Sage Body was also obtained through the fruit of the Divine Tree. However, I believe that if I have another seven or eight years to develop it in depth, my Sage Body will definitely not be weaker than his."

The ninth Wood Release clone shook its head, its tone tinged with excitement: "The main body, perhaps in seven or eight years! Have you forgotten how you developed the 'Infrasonic Radar Technique'?"

Umino Sasuke paused, then his gaze sharpened as he looked at the legs of the ninth clone: ​​"You mean... it can also simulate assimilation learning? Copy and replicate some of the characteristics of Hashirama Senju's body?"

"That's right! Come and experience it for yourself!"

Upon hearing this, Sasuke Unno did not hesitate to place his hand on the head of his ninth clone and use the Mind Transfer Technique to synchronize his consciousness with the clone.

In an instant, an experience far clearer and more profound than any he had ever had before surged into Umino Sasuke's mind. He could almost "see" how Hashirama's cells pulsed and interacted with natural energy in the warm bed built by the branches of the Divine Tree. That immense vitality and unique chakra circulation pattern was quite complex, yet it carried a certain regularity!

Although he cannot fully understand its underlying principles yet, he can directly copy and simulate this state with his powerful mental strength and perception, which will have a huge impact on the development of his immortal body.

"Unexpectedly, this improvement to the prosthetic limb has led to a shortcut to accelerating the cultivation of the immortal body!"

Sasuke Umino withdrew his hand, overjoyed.

He doesn't need to fully understand the principles behind it; as long as he can get the exact results and utilize them, that's enough. Copying and simulating is much simpler than developing.

"If Hashirama's Sage Body can be replicated and improved in this way, then what about Wood Release ninjutsu? Isn't the highest quality Wood Release in the ninja world the Divine Tree itself?!"

Sasuke Umino continued to think outside the box, and an even bolder idea took shape in his mind.

If the Wood Release techniques he uses can carry the characteristics of the Divine Tree, even if it's just a slight imitation, their power, toughness, and chakra absorption ability will undergo a qualitative change!
If it could truly reach that level, even the Sage of Six Paths would probably have to be wary of it.
Without further ado, Sasuke Unno took out another large, even thicker branch and sculpted it into a complete human skeletal framework, including the main trunk bones and the long bones of the limbs.

Number Nine, a Wood Release clone, understood and walked directly over. When his body touched the skeleton, the Divine Tree skeleton slowly merged into his body, becoming tightly integrated.

"How are you feeling?" Umino Sasuke asked eagerly.

The ninth clone stretched his body, feeling a surge of power within him: "This is fantastic! My body's resilience has increased several levels. Now, even if I unleash the Super Strength Technique at full power, I don't have to worry about it exploding!"

"I was asking about the simulation of the Divine Tree Escape Technique?"

"Of course! I can feel a faint trace of the divine tree's essence slowly permeating and assimilating my Wood Release chakra, but this will take time; it's a long and painstaking process."

"It's alright, as long as we have a direction!" Umino Sasuke was overjoyed; this step was clearly the right one again.

He didn't stop there. He used the scraps from the divine tree branches to weave and create a ninja vest for his clone, Number Nine, to wear.

With this outfit, not only can the assimilation and comprehension of the divine tree's tree-escape technique be accelerated, but the physical defense of the clone can also be greatly enhanced.

Since it's just a clone, even with a physical body, it's easy to explode under powerful attacks. With this set of Divine Tree Armor, it's basically no problem to withstand ordinary A-rank ninjutsu. Although it's still far inferior to the original Plasma Thunder God Armor, its defensive power is already quite strong.

With this series of enhancements, even if the main body doesn't directly participate in the final battle, this clone alone is enough to change the course of the battle and greatly increase the Konoha Ninja Army's chances of winning.

However, in order to minimize casualties on the Konoha side, it was necessary to make another preparation, so he finally took out a nutrient bottle.

If one needs to participate in the war but cannot be exposed, then using genjutsu to intervene secretly is undoubtedly a good choice, and the Mangekyou Sharingan stolen from Danzo is the best way to enhance genjutsu.

"Such powerful Yin Release technique!"

Sasuke Umino stared at the scarlet eyeball in the nutrient bottle, clearly sensing the terrifying energy contained within it.

"Huh?" He frowned slightly, feeling a strange throbbing and a slight itch in the pineal gland between his eyebrows, as if he had developed an instinct to devour the eyeball!
Sasuke Umino was startled and forcibly suppressed the urge to press the kaleidoscope directly onto his forehead to try it out.

"Could it be because I awakened Wood Release? Or is it that the dual cultivation of Chakra Core and Samehada has caused my body to instinctively develop some kind of 'appetite' for high-quality energy? Just like when I faced the fruit of the Divine Tree?"

Even though his analysis was reasonable, he did not act rashly.

This is, after all, the Mangekyou Sharingan, which involves the soul and Yin-Yang Release, so it must be treated with caution.

Therefore, just in case, he took out the chakra outer core, intending to use it as an intermediary filter to absorb and transform the Yin Release power in the Mangekyou Sharingan using the dual cultivation method.

With one hand holding the chakra core and the other hand taking out the Mangekyou Sharingan, Umino Sasuke then activated his chakra and injected it into the core.

Instantly, the chakra core seemed to come alive, its surface rippling with spiraling waves, emitting a powerful devouring force.

Soon, wisps of illusory Yin Release power were slowly drawn from the Mangekyou Sharingan and merged into the Chakra Core.

The outer elixir transforms into a furnace, purifying and refining these Yin-escaping powers, removing impurities such as personal will or negative emotions that may be contained within them.

Subsequently, this transformed Yin Release energy began to flow into Umino Sasuke's body.

Once this pure Yin energy entered his body, it spontaneously found its home and eventually flowed continuously towards his pineal gland between his eyebrows, where it was greedily absorbed.
