Kiyoshi's sensory abilities were constantly strengthening at this moment.

His nostrils twitched slightly, and he could smell the scent of wood and stone in the main hall, and even the lingering scent left by large snakes crawling outside.

Vague outlines continued to deepen in Kiyoshi's mind.

With his eyes closed, he smelled the scent of nature. He saw the sights of nature.

The surroundings became bizarre and colorful, shimmering with a kaleidoscopic glow.

Gradually, the colors blended together, as if gathering all colors, yet also unrelated to all colors, it was a completely new color.

A color difficult to describe in words.

Kiyoshi knew that was the color of natural energy within Ryuchi Cave.

He suddenly opened his eyes, which he had closed at some unknown point.

Around his eyes were black patterned eye shadows, and within his eyes, his black pupils appeared as golden vertical slits.

The light and shadows of the White Snake Sage, Orochimaru, Anko, and the three snake princesses constantly overlapped and trembled in Kiyoshi's eyes.

It was as if there were continuous afterimages.

Time slowed down.

Kiyoshi's senses stopped at this moment.

"Hiss… ha."

After inhaling, white mist involuntarily escaped Kiyoshi's mouth.

The surrounding natural energy rapidly gathered on his body surface, and the greenish-blue light intensified, as if he was wearing a magnificent greenish-blue cloak, illuminating the dim main hall.

It dyed everyone's images with a hint of green.

The green streams of light formed by natural energy condensed into illusory spirit snakes, coiling around Kiyoshi within the swaying, burning greenish-blue cloak.

"You have acquired the trait: [Nature's Favourite (Purple)]."

[Nature's Favourite (Purple)]

[Requirements: Natural energy affinity reaches the minimum standard.]

[Progress: Completed]

[Effect: Your physical body has undergone unknown changes. Your flesh and blood contain a hint of natural energy, and its accumulation is increased by 100% on the original basis.]

[You have received Nature's Favor. Your aura is in sync with nature, and your natural energy absorption efficiency is increased by 100% on the original basis when standing on the ground.]

[You can hear the voices of "Beasts" and understand their emotions.]

[The seeds of Wood Release begin to develop within your body, the maturation time depends on the strength of your vitality.]

[Note: Can be upgraded.]

After the new Trait prompt finished, Kiyoshi's posture also stabilized.

The images of all people and things in his eyes became solid and no longer overlapped.

Waves of power surged from the deepest part of his body.

"No wonder they looked at me strangely. ait's probably because of my natural energy affinity."

Kiyoshi realized.

[Bird (Green)] increased natural energy affinity by 20%. Coupled with [Soaring Sky (Blue)]'s 40%, it increase his natural energy affinity by a total of 60%.

For people of the Ninja World, even a 1% increase in affinity would be an incredible feat. After all, no one could achieve such a thing.

The Jūgo Clan are passively attracted to surging natural energy.

Even Six Paths Naruto, one of the strongest of the Ninja World, relied on Nine-Tails' help to gather natural energy and refine it into Senjutsu Chakra in the later stages.

Otherwise, he would most likely have died under Six Paths Sasuke's "Indra's Arrow."

From beginning to end, natural energy never treated him specially.

The same was true during the chaotic god-level battles in Boruto.

Natural energy has always existed. Rather, the Ōtsutsuki Clan planted God Trees everywhere precisely because they wanted natural energy, and they fought tooth and nail for it.

Adding the newly acquired [Nature's Favourite (Purple)], Kiyoshi now had a terrifying 160% bonus.

"Is this the power of a Sage?"

Kiyoshi raised his hand, which glowed with greenish-blue streams of light.

Compared to Kabuto's so-called transformation from snake to dragon, achieving "Perfect Sage Mode," his was more similar to that of Mitsuki, the clone cultivated by Orochimaru in Boruto.

Orochimaru created many clones, constantly wiping their memories, and finally allowed Mitsuki to enter Sage Mode.

Mitsuki's Sage Mode was quite similar to Kiyoshi's.

However, Kiyoshi could feel that his current Sage Mode had not yet reached its limit.

The greenish-blue streams of light on his body surface were a Cloak formed by natural energy attracting his own Chakra.

It was just like the Tailed Beast Cloak that Jinchuriki manifested when using Tailed Beast Chakra.

Kiyoshi had only mastered Ryuchi Cave's Sage Modr at this stage.

There were still Sage Mode from the other two Sage Regions and "Curse Seal Mode" waiting for him to learn.

Kiyoshi was very curious. What traits would he gain from these, and to what extent would they perfect his Senjutsu?

Would his physical body undergo further mutation in this state?

Kiyoshi touched the two keratinized flesh buds growing on his temples. They seemed to be in their infancy, awaiting growth.

Of course, whether they could be stacked was still unknown. This required Kiyoshi to verify.

Even if they couldn't be stacked in the end, Kiyoshi could still use the Modes formed by the four different training methods to perfect the optimal Sage Mode.

"Hiss hiss…"

The white snake in his sleeve coiled even tighter, constantly licking Kiyoshi's skin with its tongue.

Kiyoshi could now understand the true meaning of the "hissing sounds" that he previously could only guess at.

It was saying, "So fragrant."

"Jūgo clan's animal communication ability." Kiyoshi thought to himself.

Jugo in the original story could understand animal languages, and now he also possessed such an ability. It was a decent auxiliary ability.

In the vast and growing Ninja World, besides various Summoning Beasts, there were numerous ordinary creatures.

Kiyoshi's ability to gather information in the wild would now greatly increase.

"In these past few hundred years, you are the first human to master Ryuchi Cave's Sage Mode." The White Snake Sage flicked her tongue.

She looked at Kiyoshi's completely new appearance and laughed again.

This was the power Orochimaru desperately sought, and outside this hall, who knew how many dried bones were buried.

Even in a place like Mount Myōboku, countless people failed to learn Sage Mode and turned into stone statues.

Her place was not somewhere one could just come and go as they pleased.

If one could not bear the natural energy she injected from her fangs, they would turn into a snake.

Of course, during that process, she would swallow them whole.
