Mutation and Voidness

Naruto naturally would not refuse.

Chakra + Reiatsu + Senjutsu.

Naruto discovered that he seemed to have more and more cards up his sleeves.

Inside Naruto's body, Aizen was also focused on everything.

For him, natural energy was an extremely strange and interesting energy.

His curiosity towards it was no less than that of Chakra, or even beyond.

Natural energy was like energy that was the opposite of Reiatsu's.

If he could grasp the two and fuse them together, perhaps he could reach a new level.

This is a good idea. It is worth a lot of research.

However, does my world also have natural energy?

Aizen's eyes flashed as he quietly watched everything that happened.

The ordinary Chakra was condensed from the balance of body energy and spiritual energy. Senjutsu, on the other hand, absorbed the natural energy around him into his body, combining it with his body energy and spiritual energy. Sage Fukasaku began to explain Senjutsu and Chakra. Naruto sat cross-legged on the ground and listened attentively.

"Ninjutsu, who uses Senjutsu and Chakra, often has extremely strong destructive power."

"Our Mount Myōboku's Senjutsu is called Frog Senjutsu. The duration of Sage Mode is about five minutes. Come, Naruto, let's begin the preliminary cultivation of Senjutsu first."

"Remember, you must be calm. You can't have any distracting thoughts in your heart. Moreover, you need to reach a balance between Chakra and the natural energy of 1:1. If you fail, your body may be petrified or become a frog." Sage Fukasaku had a grave expression on his face.

"Let me ask again. Do you really want to learn Senjutsu?"

Seeing Naruto nod, Sage Fukasaku took a deep breath and began to let Naruto apply toad oil to his body to feel and absorb the natural energy.

Jiraiya watched this scene nervously.

Cultivating Senjutsu was extremely dangerous.

Back when he was cultivating Senjutsu, he had almost lost his life.

Fortunately, he still managed to survive in the end.

Although Senjutsu's cultivation was still very difficult.

However, once he succeeded in his cultivation, Naruto's combat power could jump above Jonin, and he might even break through to the Kage tier, which was a good thing for Konoha.

Under the guidance of the two sages, Naruto gradually entered a good state, with no distracting thoughts in his mind. Soon, the Natural Energy of the Spiritual Realm was constantly surging toward Naruto.

The speed of his cultivation was astonishing.

"Naruto is actually so sensitive to Natural Energy? His talent is so strong!" Even though Sage Fukasaku had seen countless geniuses, he had never seen a human who could cause natural energy to go berserk like this.

The natural energy formed a thick white color that continuously circled around Naruto.

But strangely, Naruto suddenly had a face full of pain.

Moreover, that aura did not seem to be Senjutsu's aura.

"Natural energy has changed?" Sage Fukasaku said in a low voice, "What a violent energy!"

The natural energy constantly turned into the energy of the pure land mentioned by the sage in mid-air and condensed on Naruto's face.

At the same time, Naruto's eyes suddenly became bloodthirsty and full of danger.

This was a terrifying gaze that Jiraiya had never seen before.

That aura and killing intent made all of Mount Myōboku's toads feel uneasy and terrified.

Even Gamabunta came to the scene and stood guard by the side in fear.

"What is going on?" Jiraiya looked at the two sages.

"This natural energy has been absorbed by Naruto's body, but it seems to have awakened something. Right now, this natural energy is being transformed." Sage Fukasaku said with a look of fear.

"I think this might be the side effect of Naruto and Kekkei Genkai, resulting in a negative personality! Right now, this personality is invading his main body."

"What can we do? Are we just going to stand by and watch?"

"Right now, the Chakra in his body is entangled with natural energy and strange power, forming a delicate balance. If we take the initiative, it will break this balance."

"I think we can only wait now."

....

When Naruto opened his eyes,

He discovered that he was actually in Zanpakutō's space.

The palace was empty, and the originally bright starry sky scene no longer existed. Instead, it was replaced by the white mist that curled up in the sky. It looked sticky and disgusting, and the air was filled with endless cold and malice.

And in the midst of the white mist, there were light spots that symbolized natural energy.

Naruto stretched out his hand and slid over the natural energy, but he could only feel the coldness.

"Jijiji." Suddenly, a burst of very negative laughter rang out in the air, and then a white shadow swept across the sky and landed next to the throne.

"This is... me?" Naruto looked over and found that the person in the white robe had the same face as him, but the expression on his face was full of negative emotions, like a crazy mental patient.

"Jjiji, it's really disgusting energy." The white shadow waved his white sword and a thick white fog lifted it, swallowing up the light spots. He looked at Naruto with an evil expression and said, "I'm finally back! From now on, I'll replace you as king!"

Under Naruto's puzzled gaze, the white shadow sat down on the throne.

However, in the next moment, his body seemed to have received a great impact, directly flying out. His chest and abdomen even caved in, and his mouth sprayed out the white-colored liquid.

He was directly sent flying at least thirty meters away, rolling down next to Naruto's feet.

He raised his head, his face filled with rage and anger. He shouted towards the throne hysterically,

"Why? Why don't you recognize me? I am clearly much stronger than this weak body! I am the king!"

But soon, he looked at Naruto and revealed an evil smile. "I understand. As long as I kill the body, I can become the king."

In his hand, the white sword with gusts of wind slashed at Naruto fiercely.

Naruto moved slightly and instantly appeared a hundred meters away. He looked at the white shadow expressionlessly, and he already understood in his heart.

This guy was his own negative, white Hollow.

From Aizen, he learned that Shinigami and Hollow had a certain relationship. Through special means, Shinigami could be Hollowfication, and Hollow could also be transformed.

And now, he was facing Hollow, the white shadow, who was composed of his negative emotions.

"A wild beast that can't control its emotions." Naruto pulled out Kyōka Suigetsu, and the Sword cried out.

This relaxed posture infuriated Hollow, and he used all his strength to slash at Naruto.

"Clang!" The two swords clashed, and violent sparks burst out. Naruto only felt his arm numb, and he took a step back.

"But the second Hollow's sword has already arrived, accompanied by hysterical laughter: "You are too weak, why not let me replace you, I will destroy the leaves of wood, I will do better than you!"

Naruto chuckled and avoided it. He kicked Hollow in the abdomen, and then he arrived behind Hollow in a flash. Kyōka Suigetsu fiercely landed.

"How is this possible?" The Hollow, who was sent flying, was shocked. He exerted strength in his abdomen and blocked Kyōka Suigetsu, but his body also smashed into the ground.

"Bang." Naruto then stepped on Hollow's face, with a mocking expression on his face.

"Trying to replace me? Is that your measure?"
