Naruto was intensely training to enhance his combat skills, and now was focusing on better understanding spiritual force. He was unsure of the best way to refer to this force, but after some time reflecting, he decided that natural energy was the most appropriate terminology for the world he lived in.

With this new understanding, Naruto realized it would be easier for him to access Sage Mode, an advanced combat technique. He closed his eyes and began to concentrate deeply. As he absorbed the natural energy around him, Naruto felt the force flowing through him, propelling him to new levels of power.

Surprisingly, in just 23 seconds, Naruto opened his eyes and realized he had entered Sage Mode without needing to burn the red orbs. He smiled, feeling stronger and more confident than ever.

"Hahaha, this is too good!" Naruto laughed out loud, knowing that his combat skills had been enhanced.

Although Naruto had discovered a new way to activate the Sage Mode using natural energy in his body, he knew this technique had its limitations. Although his reserve of natural energy was large, he could only enter the Sage Mode a maximum of three times without the help of the red orbs.

Despite this, Naruto decided it was still better to use the red orbs to activate the technique. He dispelled the Sage Mode, stood up, and changed his clothes. Then, he created a shadow clone to inform Tsunade about what he had discovered through Pain's black rod.

But Naruto wasn't satisfied with just informing Tsunade about his discovery. He wanted to make sure he was prepared to face any challenge that might arise. So, he tried to sense Nagato's presence again and found out that it would still take more than a day for Nagato to arrive in Konoha.

Although he could have gone after Nagato immediately, Naruto decided to use this time to further strengthen his skills. He knew he needed to be ready to face any situation.

Naruto was aware that, by trying to sense Nagato's presence, Nagato could be aware of his location. However, Naruto wasn't concerned about that and remained determined to find a way to further strengthen himself before Nagato's arrival in Konoha.

With that in mind, he had a bold idea. Naruto created ten shadow clones and distributed five red orbs to each of them so they could digest them. Then, he had all the clones meditate and waited about ten minutes until the orbs were completely absorbed and the clones were dispelled.

As soon as the clones disappeared, Naruto felt a huge amount of power flowing into his main body, strengthening his body and increasing his natural energy.

Satisfied with the success of the experiment, Naruto created 20 more shadow clones and repeated the test. After about 10 minutes, the shadow clones dispelled again and Naruto felt another barrier being broken in his natural energy power.

Determined to continue strengthening himself, Naruto created 40 shadow clones and repeated the process once again. In just nine minutes, the shadow clones had digested the red orbs and Naruto dispelled them in groups of ten.

Naruto continued to explore his ability to absorb natural energy with his shadow clones. After 9 minutes, the 40 shadow clones finished digesting the red orbs, and Naruto began to dispel them in groups of ten. Naruto's power increased even further after absorbing these orbs, and he felt his natural energy flowing smoothly without overburdening his body.

However, when Naruto decided to use 50 shadow clones to absorb natural energy, he began to feel an overload in his mind. But Naruto didn't let it deter him and decided to use a purple orb to facilitate absorption. With this, he was able to digest the natural energy more easily and his power increased even further.

Naruto decided to create one hundred shadow clones to divide the absorption of the red orbs and the god's arts of fire and wind. However, the presence of so many clones filled the room and caused a strong odor.

Concerned about the environment, Naruto asked the clones to spread out to other rooms in the house to meditate and absorb energy without disturbing others.

An hour passed, and the clones absorbing the red orbs had already been dispelled seven times, while those learning the god arts were finishing the first round of absorption.

Since the arts were much more powerful and different than the absorption of the red orbs, Naruto began to dispel the clones that were learning these techniques one by one, then two by two, and so on, up to a limit of five by five.

Meanwhile, Naruto's main body remained seated in the center of the room, in deep meditation. He could feel the natural energy being drawn into his body, filling every cell with waves of strength. The energy strengthened him more and more, and he felt that he had broken through another barrier in his natural energy power.

Naruto was in the room meditating, feeling the Natural Energy flowing through his body. It was a pleasant sensation as if every cell was being filled with waves of strength. After about twenty minutes, Naruto opened his eyes, and a bright green light illuminated them, with flames burning in the background. He exhaled slowly, with his breath laden with scorching Natural Energy, as if he were containing sparks.

Feeling the power circulating through his body, Naruto smiled satisfactorily. He clenched his fists and felt the energy flowing through them. The blazing flame burned in his left hand, while the wind blew softly in his right hand. Suddenly, the flame turned into a red light, flowing towards the wind and merging with it.

The fusion process was very natural and effortless for Naruto, who watched in amazement. Then, the flame and the wind began to grow and strengthen each other, enveloping all of Naruto's hands. It was an impressive spectacle, the union between fire and wind creating an even greater power than when separate.
