Konoha: Naruto, trained by Aizen

"Actually, I am the reincarnation of Ashura." With that, he punched Kaguya in the stomach, sending her flying.

"All things in the universe, flowing blades like fire." Waves of fire surged higher and higher, instantly engulfing Kaguya.

However, Kaguya, who was on guard, used Yomotsu Hirasaka to escape.

Her face still showed shock and anger.

"You are the reincarnation of Asura?" she asked incredulously.

Although she couldn't believe it, during their previous close contact, she could feel that Naruto's aura did indeed have the scent of a descendant.

"You actually betrayed chakra and embraced the Pure Land?" What angered her even more was Naruto's stance.

The Ninja World and the Pure Land have always been irreconcilable enemies.

The victor is king, the loser is a bandit.

The victories of past battles have proven that chakra is more powerful than the energy of the Pure Land system.

As his own descendant, he actually abandoned the infinitely potential of chakra and instead sided with the loser.

Such a decision is incredibly foolish.

That's so infuriating, I just want to kill him.

"It seems you have some misunderstanding about chakra." Looking at Kaguya's expression, Naruto understood what she was thinking.

"Chakra is a thing of the past."

“However, this does not mean that I have given up on chakra. As a product of the old era, chakra still has some value.” Naruto said calmly, condensing a Rasengan made of chakra in his right hand, which spun rapidly under the bright sun.

"Both chakra and spiritual pressure have limited limits, but chakra is more limited in comparison." Naruto's calm tone drew attention.

"Is spiritual pressure also limited?" Sasuke paused for a moment, then looked at Naruto in a daze.

In his original understanding, chakra had been eliminated, and spiritual pressure, a product of the new era, should be the main theme of the future world.

But judging from Naruto's words, his vision and perspective seem to have surpassed his own and reached a new realm.

“Both spiritual pressure and chakra have certain limitations.” Naruto glanced at Sasuke and his voice echoed throughout the space.

"To be precise, all energy systems are not static, but rather elevated to a new level through comprehension, integration, and mastery. Energy systems may be universal, but one's own energy system is unique."

“While spiritual pressure is indeed formidable, chakra cultivated to its peak is not weak either.” Naruto’s Rasengan quickly expanded to the size of a meteorite and slowly descended from the sky.

"Boom boom boom." The entire space trembled and collapsed, with fragments constantly falling from the air.

"Such fluctuations?! I never imagined your chakra had been cultivated to this level." Sasuke's expression shifted.

"Chakra has no effect on me." Kaguya remained unmoved, snorted coldly, and the next moment, the Rasengan that seemed capable of bringing about the end of the world was completely absorbed.

As the progenitor of chakra, she is able to absorb all ninjutsu.

"Is that so? I think I should have said that." Naruto's eyes were mocking. "Only through fusion and integration can the energy system reach new heights. Do you think someone with such awareness would want to study pure chakra?"

"Buzz." As soon as she finished speaking, a strange fluctuation was generated, and then Kaguya showed an extremely shocked and painful expression.

Her body continued to swell, and white spiritual pressure emanated from her mouth.

"By fusing spiritual pressure and chakra, I've created a new energy system. That's what I've achieved so far. However, the biggest drawback right now is that the power of spiritual pressure is too strong, and the degree of fusion between chakra and it isn't enough." Naruto slowly walked towards Kaguya.

"This is one of the reasons I unsealed you. I want to see what's so special about the chakra of the progenitor of chakra." With that, Naruto reached his right hand toward Kaguya's chest and heart.

He wanted to pluck Kaguya's heart and absorb her chakra.

"Although Ashura's chakra is pure, it is far too weak compared to yours. I believe that as long as I possess your chakra, my spiritual pressure can be completely integrated with the chakra, and I will be able to completely transcend the Pure Land and the Ninja World."

"Boom boom boom." Explosions occurred continuously inside Kaguya's body, and blood kept spitting out of her mouth. Her expression was weak, and she collapsed helplessly to the ground.

"Is this the end? The progenitor of chakra has far less capacity than I thought." Naruto's voice was filled with undisguised disappointment.

Kaguya Otsutsuki, despite being the progenitor of chakra and possessing power surpassing all other ninjas, had pitifully little combat experience, and her fighting style and thinking were extremely immature.

He even foolishly absorbed his own Rasengan.

If she were to perceive it carefully, she would definitely be able to notice that something was wrong with the Rasengan.

"Heavenly Hand Power." Just as Naruto's hand was about to penetrate Kaguya's chest, Hinata activated her Child Technique, instantly switching her body with Kaguya's.

"Spin." A powerful shockwave erupted from Hinata's body, blasting Naruto a hundred meters away.

"The Hand of God." White spiritual pressure erupted from the twin children and merged into Kaguya's body.

Kaguya, who had been pale, quickly recovered, and the hidden injuries in her body were rapidly repaired.

"Looks like Naruto, you've raised a monster." Sasuke said gloatingly, arms crossed.

"It's fine, it would be too boring to end like this." Naruto conjured another Rasengan in his hand and casually tossed it toward Hinata.

"After the spiritual pressure and chakra merged, the Byakugan evolved, and its Child Technique is much more practical than the Rinnegan. Unfortunately, that's all it is." Continuous Rasengan filled the sky, scattering towards the area where Hinata was.

Each Rasengan has the power to directly destroy Konoha.

"Return to Heaven." Horrifying meridians appeared in Hinata's eyes, and a white vortex appeared around her body, with spiritual pressure and chakra swirling around, forming a huge oval.

"Boom." A dozen or so Rasengans slammed into the Rejuvenator, colliding with each other under the guidance of the cyclone, and the aftershocks of the explosions were also absorbed by the Rejuvenator.

These terrifying energies constantly surrounded Hinata's body, forming a natural protective shield.

"Reverse!" The Byakugan burst forth with a blinding white light, and the protective shields instantly condensed into a ball of light, shooting towards the remaining Rasengan.

With a deafening roar, the entire area collapsed once more, completely neutralizing Naruto's Rasengan.

but.

Hinata was already panting, while Naruto's breathing remained perfectly calm.

"It's truly astonishing that the eyes have reached this level so soon after awakening," Naruto couldn't help but exclaim.

"This must be the new height of bloodline limit. It seems that both oneself and bloodline limit can be continuously broken through. You have embarked on a completely different path from mine. It is really hard to kill you."

Naruto felt a pang of regret for his lack of talent.

Hinata possesses the will and potential of a strong person; if nurtured properly, she might surpass Sasuke in the future.

"Yomi Hirasaka." Kaguya, now fully recovered, used the same trick again, opening the black gate and appearing behind Naruto.

"Together, we will kill the ashes."

Bones shot out from her palm.

This technique is one of Kaguya's ultimate skills; those pierced by the bone will have their bodies gradually decay like those reanimated.

"A mirage." This time, Naruto dared not be careless and directly twisted the All-Killing Ash Bones.

“If you get stabbed, even the body of a Shinigami (death god) cannot resist it, and you might even be defeated directly.” Naruto’s eyes were filled with fear.

"While chakra may not be powerful, it can be used in many ways."

"Shoot him, Divine Spear!" Naruto's Zanpakuto suddenly transformed into a white light, piercing Kaguya's abdomen.

The sword was restored, with Kaguya's blood still on it.

"This sword?!" Kaguya stared in disbelief at the shrinking Zanpakuto, clutching her stomach in pain.

"My injuries have not healed."

Kaguya Otsutsuki's body is not only immune to all ninjutsu, but also possesses extremely strong self-healing abilities.

Naruto and Kaguya then engage in battle, with Hinata assisting Kaguya from the sidelines.

Combined with her bizarre child-based magic, Kaguya was at a slight disadvantage for a time.

However, Naruto could sense Kaguya's weak combat awareness during the battle.

It can be said that Kaguya has always been accustomed to crushing others with strength, and has never had a battle where the two are evenly matched.

It's like having brute force but nowhere to unleash it.

However, as the battle intensified, her combat awareness also showed a rapid improvement.

"Eighty Gods Vacuum Strike!" Chakra gathered in Kaguya's hands, condensing into thousands upon thousands of fists in the air.

"Getsuga Tenshou." Naruto even used all the Shikai he had learned, continuously shooting out black Getsuga Tenshou from the blade.

A violent burst of energy erupted, and the shockwave swept away everything below.

"Kill Ash Bones Together." Kaguya unleashed another deadly attack.

"Shoot him, silver spear." A flash of white light, and the silver spear deflected it.

"Sit upright in the frost, Hyōrinmaru." The space froze, and heavy snow fell from the sky.

This is a Zanpakuto ability copied from Toshiro Hitsugaya.

It can use spiritual pressure to freeze the air and form an ice dragon.

This was also the first time Naruto used Hyōrinmaru.

You could say he's already started playing.

The ice dragon roared and swept towards Kaguya.

"Return to Heaven." Hinata used Return to Heaven a second time with great effort.

"Together, we will kill the ashes."

Kaguya temporarily put aside her dislike for Hinata and used her ultimate technique to fight alongside Hinata against Naruto's Hyōrinmaru.

"Crescent Moon Sky Rush".

"Flowing Blade Like Fire".

But Naruto was completely caught up in the fun, unleashing a barrage of attacks on the two of them.

The two struggled to hold on, and soon their advantage turned into a disadvantage.

However, Naruto gained new insights into his abilities through his relentless attacks.

He hadn't had enough fun in the previous battles.

Although Sasuke is strong, he certainly cannot stop his relentless attacks.

After Kaguya and Hinata team up, one of them possesses Yomotsu Hirasaka, enabling them to jump between spaces.

Another child technique can absorb the abilities of Kido and Zanpakuto.

Although their offensive capabilities are not outstanding, their defensive capabilities are absolutely unparalleled.
