Intense Sun

"Secret Technique: Four Red Yang Formation!"

As the four Hokage initiated the barrier jutsu, four enormous curtains of light surged upward, forming a massive cube that enveloped the Ten-Tails.

This grand spectacle left the allied shinobi in awe.

"Is this the legendary Barrier Technique that requires four Hokage-level Shinobi to use? It's incredibly powerful! Much stronger than the Four Purple Flames Formation," Might Guy clenched his fist as he watched the Four Hokage immobilize the once-arrogant Ten-Tails. His blood boiled with excitement, and he wished he could charge in and pummel the Ten-Tails right now.

"Roar!"

Seeing the immense curtains of light around it, the Ten-Tails screamed angrily. It then gathered Chakra again, preparing to unleash its Tailed Beast Ball.

Chakra continually converged on the dark red flower on its body, forming a Tailed Beast Ball the size of a mountain once more.

The Ten-Tails intended to break free from the Four Red Yang Formation using the Tailed Beast Ball.

"Everyone, the Ten-Tails is attempting to breach the barrier; stay vigilant," warned Minato as he witnessed the Ten-Tails concentrating a devastating Tailed Beast Ball once more.

"I see," said Hiruzen Sarutobi with his gaze fixed on the massive Tailed Beast Ball. He took a deep breath and stabilized his Chakra.

"Heh, just watch," Tobirama Senju said with a scornful smile as he observed the Ten-Tails attempting to break through the Four Red Yang Formation. Breaking through this barrier was just a wishful thinking.

The Allied Shinobi Forces began to gather around the four Hokage.

Boom! Boom! Boom!!!

The Ten-Tails' powerful Tailed Beast Ball collided with the barrier, causing a loud sound upon impact. Since the top part of Four Red Yang Formation was not closed, the residual shockwaves of the tremendous energy spilled from there. Some Sensor Type Shinobi were worried as they sensed the frightening energy surging from above. Could this terrifying Tailed Beast Ball really be stopped?

However, the Allied Shinobi Forces were relieved soon, because despite the grandeur of the Ten-Tails' Tailed Beast Ball, the enormous Four Red Yang Formation remained completely unscathed. In contrast, the Ten-Tails ended up lying on the ground, humiliated, as its Tailed Beast Ball failed to break the barrier.

Seizing the opportunity, Hashirama entered Sage Mode, pressed his hands together, and exclaimed, "Sage Technique: Gate of the Great God!"

Bang! Bang! Bang!

Red torii from the sky continuously rained down, smashing onto the Ten-Tails' tails.

"Seal Ten!"

Finally, all ten of the Ten-Tails' tails were pinned down to the ground by Hashirama's Gate of the Great God.

"Roar!"

Feeling a significant amount of its Chakra being sealed, the Ten-Tails let out an agonizing roar.

But Hashirama was not finished. He shouted, "It's not over yet! Seal Head!"

After saying that, a massive red torii descended from the sky and crashed onto the Ten-Tails' neck, completely immobilizing it on the ground.

Only Hashirama could maintain the Four Red Yang Formation while still freely using Sage Techniques thanks to his overwhelming amount of Chakra.

After sealing the Ten-Tails, Hashirama created five wooden clones.

"Little Tobirama and all Allied Shinobi Forces, I'll open a passage for you to attack the Ten-Tails," Hashirama said.

Hashirama's wooden clones moved swiftly, and soon, they went to each edge of the barrier. With a slight hand gesture, they opened entrances for the Allied Shinobi Forces to enter.

Another wood clone then jumped onto the cliff where Madara was and said, "Madara, sorry to keep you waiting. I'll be your opponent!"

Madara loosened his grip on his fan and sat down on the ground, responding calmly, "I'm not interested in clones. I'll wait for the real you."

Only a battle against Hashirama's real body could give him his long-awaited thrill. He wasn't interested in the clones.

Just as Naruto was about to enter the Four Red Yang Formation to attack Ten-Tails, a familiar figure leaped in front of him.

Naruto wasn't surprised; he had already sensed that person's Chakra. He smiled and said, "Sasuke, you're a bit late this time."

"Sasuke..." Sakura looked at him with mixed feelings.

"Just because I'm late, doesn't mean I'm useless. Just don't hold me back, Naruto," Sasuke immediately made a snide remark as he saw Naruto.

"Well, then, watch closely, just don't get shocked by how strong I've become," Naruto said proudly as he entered Nine Tails Chakra Mode, radiating a dazzling golden light.

"Let's go!" Naruto smiled and rushed in first.

Sasuke and Sakura followed closely, entering the Four Red Yang Formation.

Despite being suppressed by Hashirama Shinju, Ten-Tails' body was riddled with numerous dots that could drive fear into the hearts of those who gazed upon them.

Those dots and protruded from Ten-Tails and transformed into small creatures resembling Ten-Tails that guarded Ten-Tails from the incoming Allied Shinobi Forces.

"It can make fission of itself? It seems this creature doesn't want anyone near its main body," a Shinobi speculated.

In any case, now that they had entered the Four Red Yang Formation, there was no turning back. The Allied Shinobi Forces began battling Ten-Tails' fissions.

Naruto and Sasuke particularly stood out; Naruto could obliterate dozens of fissions with a single Rasengan Shuriken, while Sasuke used Amaterasu to incinerate several fissions at once.

Sakura's strength was also impressive; her powerful punches shattered the ground beneath her, though she didn't take out as many fissions as her teammates.

However, despite their efforts to eliminate the fissions, they were vastly outnumbered. The Ten-Tails' fissions seemed endless, and if they fought them one by one, the Allied Shinobi Forces would exhaust themselves before even reaching the Ten-Tails' main body.

Sai attempted to attack the Ten-Tails by riding his hawk drawing, but he was soon shot down by the fissions.

After observing the situation, Naruto, Sasuke, and Sakura summoned their respective Summoned Beasts. Three gigantic Summoned Beasts appeared on the battlefield, and this scene was like the return of the Legendary Sannin, giving the Allied Shinobi Forces a hint of nostalgic feelings and admiration for the new generation.

Fighting side by side with Naruto and Sasuke, Sakura felt a sense of fulfillment. She thought to herself, "Lady Tsunade, it seems like I've finally caught up to them."

"Everyone, step aside a bit and let me clear the way for you," 

Just as Naruto and Sasuke were about to order their Summoned Beasts to charge at the Ten-Tails, a seemingly less important voice entered everyone's ears.

The Allied Shinobi Forces turned to the source of the sun and saw a person radiating a bright red light as he approached them with a sword on his hand.

This person was none other than Nagasawa, who had just used Sun Breathing after entering the Sage Mode. He had completed his training just in time and had managed to enter Sage Mode.

Nagasawa wasn't late because he simply wanted to show off. He had been honing his Sun Breath within God Tree's space, fearing that using it would interfere with Hashirama's Divine Gate.

Due to his experiences in the simulation space, along with extensive research in the real world, Nagasawa grasped Sage Mode fairly. 

He was worried that his Breathing Style might conflict with the Sage Mode, but upon activating the Sun Breathing with Sage Mode, he realized there was no problem; in fact, the combination was more effective than using normal Chakra, although it was more draining.

Nagasawa advanced slowly, but with each step, his momentum grew stronger. When he reached the position of the Allied Shinobi Forces, his aura reached its peak. It felt like the blazing sun was descending upon the entire battlefield.

Everyone on the battlefield, friend and foe alike, turned their attention to this swordsman who had emerged out of nowhere.

"This guy is so powerful..." Even Hashirama, maintaining the Four Red Yang Formation, couldn't help but acknowledge Nagasawa's power.

Although Hashirama initially thought Nagasawa might be a clone, he soon realized that Nagasawa was truly an inhabitant from another world instead of a clone.

Tobirama also came to terms with this. He even thought that he might have been able to become stronger if he worked harder like himself from another world.

Seeing the sudden surge of power, Hashirama was excited. "Go, Little Tobirama!"

His excitement came from watching the strength of this alternate-world brother. Nagasawa was genuinely powerful.

"Oh, I didn't expect another Tobirama from another world. How interesting," Madara, sitting on the cliff, showed an intrigued expression.

Madara thought that only Hashirama could provide him with the thrilling battles he sought. Now it seemed there was another formidable opponent.

"Heh, an alternate-world Tobirama? This is interesting."

The entire Allied Shinobi Forces moved aside, giving Nagasawa enough room to unleash his power.

As Nagasawa swung his sword, the red glow on his body transitioned into a faint golden radiance. At the same time, his sword turned black because of Color of Arms Haki. With both Sage Mode and Sun Breathing, it wasn't just the crimson flames mixed with gold, but pure golden flames burning on his sword.

The golden flames caused the temperature in the vicinity to skyrocket. The Shinobi near Nagasawa began to sweat profusely as if they were standing in a blazing furnace.

Sensing the horrifying aura of the golden flames, Ten-Tails, despite being sealed, couldn't rest easy. It controlled its fissions to act as shields against the approaching Nagasawa and attempted to counterattack.

But Nagasawa didn't use his usual Sun Breathing 13th Form. Instead, he decided to unveil a new technique he had thought of while perceiving the sun with Transparent World.

However, thanks to the Sage Mode, he could now utilize this technique in the real world.

The sun is both light and hot, dispersing darkness and bringing warmth. The sun, high in the sky, held a special significance and is greatly revered.

Therefore, Nagasawa named this Technique

"Blazing Sun!" Nagasawa's entire body burst with power as he unleashed a single strike, containing all his understanding.

Whoosh! Whoosh! Whoosh!

The intense gusts of wind created by Nagasawa's swing sent rocks flying.

To withstand the fierce winds, some Shinobi even applied Chakra on their feet to prevent themselves from being blown away.

"It's so bright... and dazzling!"

Some Shinobi initially planned to observe how Nagasawa would attack but were forced to shield their eyes from the sudden, intense light. The abrupt eruption of such powerful light in the midst of darkness was unbearable.

As Nagasawa's golden flying slash wave struck, the entire battlefield was illuminated as if it had transitioned from night to noon in an instant.

At the same time, the terrifying temperature of the golden flame caused those nearby to break into a cold sweat, feeling as if they were standing in the midst of a blazing furnace.

Witnessing the incredible display of light and power, the ninja alliance, with hope in their eyes, hoped that this attack would finally vanquish the Ten-Tails.

The fissions caught in Nagasawa's attack disintegrated instantly, disappearing into ashes. It was as if they had been affected by a Time-Space Ninjutsu and vanished in an instant.

Nagasawa's attack moved with incredible speed and was about to strike Ten-Tails. The only barriers left in its path were three fissions.

The entire Allied Shinobi Forces watched with expectant eyes, hoping this attack would incinerate the Ten-Tails once and for all.

The fissions were incinerated by the golden flames before they even touched it.

The golden flying slash wave was too fast; it effortlessly tore through the three walls of fissions and struck Ten-Tails' body.

To avoid damaging Hashirama's Divine Gate, Nagasawa aimed his attack at Ten-Tails' lower body.

"Roar!!"

The impact of such a powerful attack made Ten-Tails let out a horrifying scream, echoing throughout the battlefield.

"Well done! This damn monster gets what it deserves!" The Allied Shinobi Forces cheered upon hearing Ten-Tails' agonizing cries.

With so many casualties among them, there was no room for sympathy. They celebrated the monster's suffering, knowing that victory was within reach.

However, despite the substantial damage dealt by Nagasawa's attack, it did not kill Ten-Tails.

Nonetheless, it had eliminated a significant number of fissions, creating an opening for the Allied Shinobi Forces to press onward.

As the Allied Shinobi Forces advanced, something unexpected occurred.

The space on top of Ten-Tails' head space suddenly distorted, and a heavily wounded figure came out.

"It's Obito Uchiha!" The Allied Shinobi Forces immediately recognized the man who had pretended to be Madara Uchiha and initiated the Fourth Great Shinobi War. 

"Did Kakashi do it? Remarkable!"

The morale of the Allied Shinobi Forces suddenly soared. The Ten-Tails was trapped and heavily injured.

The initiator of the war, Obito Uchiha, was seemingly on the brink of death, and victory seemed imminent.

Watching Obito emerged from Kamui Dimension in such a state, Madara expressed some disappointment.

"That guy is already done for. It's time for me to claim what's mine. I had originally planned to have a showdown with Hashirama before becoming the Ten-Tails' Jinchuriki, but it seems that won't be possible now."

Obito had Rinnegan and still lost. Because of him, he couldn't have an even battle with Hashirama, which was what he truly desired. Defeating Hashirama after becoming Ten-Tails' Jinchuriki wasn't enjoyable. He wanted to defeat Hashirama under equal terms.

Madara began to use a Ninjutsu, preparing to control Obito.

As for Minato, at the moment Obito fell onto the head of the Ten-Tails, a complex expression appeared on his face.

"So it's you..."
