Naruto: I am Uchiha Shirou-Chapter 212: Naruto: I am Uchiha Shirou []

Kikyo Mountain.

"Quick! The toxin in the body of the Jonin from the original unit has already been extracted using the Delicate Illness Extraction Technique. Immediately assign a Chunin-level medical ninja to stabilize his condition."

"Understood!"

"Hurry and retrieve any severed limbs. As long as it's within a certain time frame, they can still be reattached..."

"Minor injuries and external wounds should first rely on Katsuyu's healing. For serious external injuries, Katsuyu should also be used to stabilize the condition and prevent further deterioration. Prioritize the rescue of poisoned and internally injured patients..."

Even after their victory, the Konoha ninjas on Kikyo Mountain didn't rest. Orochimaru organized the remaining combat-capable ninjas to maintain vigilance, while also dispatching others to clean up the battlefield.

Meanwhile, in Konoha's main camp, amidst the constant wails of the injured, Tsunade remained calm as she issued orders. Her hands never stopped working, continuously used her medical ninjutsu to treat critically injured patients one by one.

Although Konoha seemed to have suffered significant casualties in this battle, experienced ninjas could see that most of Konoha's injured had their conditions stabilized.

Only a small number of ninjas hit by jutsu or poisoned required emergency treatment.

At this moment, Tsunade, the Medical Saint of Konoha, the strongest in both individual and group medical ninjutsu across the ninja world, once again proved her unrivaled status.

Even without setting foot on the battlefield, she could continuously heal ninjas for Konoha from the rear.

In contrast, the allied forces of Cloud, Sand, and Stone, retreating to their camp in the distance, were in far worse shape.

"Hang in there, Saburo! Saburo!"

"Cough... Save me... please save me..."

"I still want to go home. I still want to see my mother..."

"Damn it, where are the medical ninjas? Hurry up!"

The rear of the allied ninja forces was in utter chaos. The camp was filled with the screams of countless injured ninjas and the heart-wrenching cries of despair.

"Focus on stabilizing the conditions of our comrades first!"

For the allied forces, most injuries were temporarily stabilized by experienced ninjas performing makeshift first aid. However, there were far too few actual medical ninjas.

Seeing this scene, Ōnoki, the Third Tsuchikage, couldn't help but frown deeply and sigh in frustration.

"Konoha may have more medical ninjas than us, but not by much. Yet Princess Tsunade alone is worth all the medical ninjas of the Five Great Shinobi Villages combined!"

If Tsunade's medical ninjutsu was already unmatched in the ninja world, then when paired with her summoned creature, Katsuyu, which could perform large-scale healing, it became an overwhelming advantage.

In small-scale skirmishes, Tsunade's medical abilities might not stand out as much, even if they were impressive.

But in large-scale ninja wars like this, Tsunade became an irreplaceable cornerstone on the battlefield.

"Everyone, make way! The medical unit from Sunagakure has arrived to assist!"

Amidst the chaos, a group of nearly a hundred medical ninjas from Sunagakure hurried into the allied camp's medical zone. Seeing this, many injured ninjas felt a glimmer of hope and couldn't help but cry out in relief.

Watching this scene, the Fourth Raikage candidate, A, frowned.

"Sunagakure's puppet masters are all skilled in poison-making techniques. Any puppet master who excels in poison-making is also an excellent medical ninja. Even those who aren't experts in poison are proficient in medical defense..."

Among the Five Great Shinobi Villages, aside from Konoha, Sunagakure had the second-strongest medical system.

After all, medicine and poison often went hand in hand.

Next in line was Iwagakure.

Looking at the young Fourth Raikage candidate, A, Ōnoki's expression grew grave.

"You brat, I'll admit that there has always been deep hatred between Iwagakure and Kumogakure. But this time, you've seen Konoha's true strength—the power of the Mangekyō Sharingan and Konoha's military might!

We must work even more closely together. I don't expect our ninjas to set aside their grudges, but in this war, every decision we make will affect the future of our villages."

Hearing Ōnoki's grim tone, A's expression also became serious. He eventually nodded.

"I understand, Third Tsuchikage. I'll keep the Cloud ninjas in line."

"I'll do the same with the Stone ninjas."

Konoha's overwhelming strength had placed immense pressure on them. Despite their numerical advantage, the Allied forces had failed to gain the upper hand in the war.

"Just look at the state of our injured ninjas!"

Ōnoki's face darkened as he pointed to the injured in the Allied forces' camp. The cries of countless ninjas echoed through the air, with some unable to endure the pain and taking their own lives.

Many ninjas, unable to receive treatment in time, saw their injuries worsen, increasing the cost of medical supplies. Some simply couldn't make it.

"On the other hand, thanks to Tsunade's presence, Konoha's casualty reduction after every battle is like fighting on a completely different battlefield."

Ōnoki's heavy words echoed as Sunagakure's Elder Chiyo approached with a similarly grave expression.

"During the Second Shinobi World War, we in Sunagakure already witnessed the terrifying prowess of Tsunade's medical ninjutsu.

Even in battles where both sides fielded two thousand ninjas, after several consecutive fights, Konoha could still maintain the morale and combat strength of about 1,500 ninjas.

Meanwhile, due to casualties, we in Sunagakure were down to less than 800 combat-ready ninjas after just half a month."

Chiyo sighed as she looked at Ōnoki and the Cloud ninjas.

"This is the terror of Konoha. They have the strongest medical system in the ninja world and a ninja like Tsunade. If this drags into a prolonged war, Konoha's resilience will surpass anything we can imagine!"

Hearing the two elders discuss Konoha's terrifying foundation, the young candidates for the Fourth Raikage, A, and Kazekage, Rasa, exchanged glances, both wearing serious expressions.

"We understand now. The battlefield isn't just about direct combat. The medical system and logistics... all of these combined are the true battlefield!"

Chiyo and Ōnoki's serious attitudes reflected two major concerns. First, the appearance of the Mangekyō Sharingan on the battlefield reminded them of the fearsome Madara Uchiha, who once terrorized the ninja world.

Second, Konoha's immense strength was exerting pressure on the younger generation of Jonin in other villages, suppressing the hatred and divisions among the three allied villages.

This was why Chiyo had immediately sent Sunagakure's medical team to assist after stabilizing their injury.

Konoha's strength and foundation were not something any single village could defeat alone.

...

As night fell over Kikyo Mountain, a brief calm settled over the battlefield.

"Your eyes may feel uncomfortable now, but continued use will help you adapt to this new power..."

Inside a tent, Tsunade examined the Mangekyō Sharingan and rubbed her tired temples. She applied specially prepared eye drops to soothe the exhaustion in the Sharingan before advising:

"The discomfort you're feeling now is like a ninja recovering from an exhausting battle. Your Mangekyō just isn't used to such high-intensity combat yet."

Hearing Tsunade's explanation, Shirou, lying on the bed, slowly deactivated his Mangekyō and nodded in understanding.

"I see. No wonder I didn't feel anything during the battle itself, but afterward, my eyes felt stiff and fatigued."

Just as Shirou began to sit up, a red figure suddenly clung to his neck. Uzumaki Kushina's crescent-shaped eyes gleamed mischievously.

"Sister Tsunade, why don't you let Shirou bite me? That way, he can recover faster and get his eyes used to high-intensity combat!"

Seeing Kushina, Tsunade raised an eyebrow and smirked coldly.

"Bite you? Adapt to high-intensity combat? Just like how you tricked me in the first place?"

When she saw Tsunade glaring at her, Uzumaki Kushina immediately looked embarrassed. She naturally knew what Tsunade was referring to, and her eyes darted away. However, her personality wouldn't let her admit defeat so easily.

"Sister Tsunade... I didn't trick you at all..."

Kushina turned around and clung to Tsunade, acting spoiled. However, this time, Tsunade slapped her hand away in mild irritation. Her eyes carried a warning as she cautioned:

"Kushina, you absolutely must not reveal your unique constitution carelessly! This is war! The special constitution of the Uzumaki clan doesn't just consume ordinary chakra!"

At this point, Tsunade's expression became serious as she fixed her gaze on Kushina and said in a grave tone:

"Your body's ability to absorb chakra from your blood to heal injuries isn't as simple as you think. Based on my research, it's clear that every time you use this ability to heal, what's being consumed is your powerful life force...

Although this life force can recover under normal circumstances as long as it isn't damaged too severely, and it won't affect your lifespan, don't forget! This is the battlefield!"

The Uzumaki clan's special constitution allows unique energy to be produced within their bodies, much like the special chakra generated in the brains of the Uchiha clan when using the Sharingan.

"If this special energy is overused, it's just like the Mangekyō Sharingan. The life force you lose cannot be recovered. If you control the consumption to a certain extent, it can regenerate..."

Listening to Tsunade's warning, Kushina obediently nodded. She wasn't stupid.

If this ability were exposed, countless people would come after her. Kushina herself was already considered Konoha's ultimate weapon.

Once people feel you didn't save their companions or family members, they'll hate you!

You might argue that you only lost a little bit of your lifespan, but from their perspective, they lost loved ones, their companions!

For each person, it may seem insignificant, but when accumulated, it becomes a disaster!

"Kushina, remember! Never underestimate the greed and malice in people's hearts!"

Having experienced firsthand how cruel people can be, Tsunade's stern warning made Kushina quickly nod in fear.

"Sister Tsunade, don't worry. I'm not stupid. Last time, during the battle on the Land of Rain battlefield, I activated this ability, but because of the barrier formed by my adamantine chains, no one noticed.

The only people who know are you, Sister Tsunade, Sister Mikoto, Shirou, and a few other ninja like Lord Orochimaru. They're all trusted allies of the Senju and Uchiha clans..."

Seeing Kushina's understanding of the gravity of the situation, Tsunade's tightly furrowed brows slowly relaxed.

But this relaxation was due to Shirou's fingers gently massaging her temples to help her unwind.

"The Uchiha's upper-ranked ninja has already issued a clan-wide gag order. They won't speak of this. The Senju clan is even less of an issue. As for Orochimaru..."

At this point, Shirou couldn't help but smile. One could say that Orochimaru was the most trustworthy in this regard.

At the same time, Shirou recalled the original story of Karin's mother, who was drained to death while healing others.

Even in a small village like Kusagakure, they must have known how precious this kind of constitution was. Under normal circumstances, it should have been cherished.

But instead, she was drained to death. It was clear that it wasn't the big things that killed her, but the accumulation of small, careless acts over time, causing her life force to drain away until she ultimately died.

"Sister Tsunade, thank you for your hard work."

As she enjoyed the rare moment of relaxation, Tsunade sighed, her eyes half-closed in fatigue:

"Luckily, we have Kushina. With your ability to summon Katsuyu, I've been able to save a lot of chakra. The injuries in the camp are now stabilized, and reinforcements from the village will arrive in two days.

This war has just begun. Don't get too cocky, though. The opponent you faced today, Ōnoki, was merely testing your strength and wary of your dōjutsu."

Shirou naturally understood. Ōnoki was one of the strongest Kage among the Five Great Shinobi Villages. The only one who could rival him was the Third Raikage.

Ōnoki's ability to fly alone gave him a significant advantage. No one could withstand his Dust Release head-on, but at the same time, Ōnoki couldn't endure the Third Raikage's attacks either.

"Dust Release truly is a powerful jutsu. Even the so-called absolute defense of the Susano'o is somewhat inadequate before its power."

Thinking about today's battle against Dust Release, Shirou couldn't help but show a serious expression.

If not for Ōnoki's concern about the Dust Release potentially harming his own side's ninja, if he had fought without restraint, even Shirou would have found it troublesome.

Dust Release is truly inescapable!

"Mikoto will also be arriving soon. You're sly, though, pretending to shed bloody tears to mislead the enemy and make them think your Mangekyō Sharingan has a weakness."

Tsunade couldn't help but tease him with a laugh.

"When Mikoto arrives, there will be a second pair of hidden Mangekyō Sharingan by your side..."

At this moment, Tsunade's eyes glimmered with schadenfreude. If someone were to force Mikoto to use her Mangekyō Sharingan, the ensuing chaos would be quite the spectacle.

But Shirou narrowed his eyes, thinking instead about the enemies lurking in the shadows.

"Mangekyō Sharingan, huh! Such immense power... If you don't give these people a glimmer of hope, even fleas can become an annoyance."

The bloody tears from the Mangekyō Sharingan, revealing the risk of blindness, served as a deterrent for both the allied forces of Ōnoki and the hidden schemers in the village.

"All right, take this chance to rest properly. The war has just begun. Facing the combined forces of the Four Great Shinobi Villages this time is going to be a real challenge!"

Regarding the war, Tsunade also looked solemn. The current situation was no longer one where an additional Kage-level combatant or two could determine the outcome.

The First Shinobi World War had pushed the military capacity of all the major villages to its limits. Their homeland resources were completely saturated, and further growth required external conflict.

As a result, this war would likely drag on for years. Only after all the major villages had been severely weakened, their vitality nearly extinguished, would the fighting finally cease.

"Once the chariot of ambition begins moving, it won't stop so easily."

Tsunade's expression turned complicated as she said this, her gaze drifting toward Shirou.

Sensing Tsunade's thoughts, Shirou seemed to understand her sentiment and nodded gravely.

"Sister Tsunade, don't worry. Ambition must be matched with strength. Until I have the power to suppress the entire shinobi world, I won't actively provoke a war!"

The implication was clear: if he did have the power to dominate the shinobi world, he would initiate a war of unification.

...

In the 46th year of Konoha, the Third Shinobi World War had fully erupted.

At Kikyo Mountain, the allied forces of Kumogakure, Sunagakure, and Iwagakure launched a brutal assault on Konoha. The Four Great Shinobi Villages had formed an allied force to wage war against Konoha.

As the war unfolded, countless smaller nations were dragged into the conflict. Only a few remote or overseas countries were fortunate enough to escape the flames of war; the rest were pulled into the great nations' struggle.
