With chakra fluctuations of this magnitude, had he done this outside, the Hyūga clan.....and anyone with sensitive perception...would have noticed long ago.
As time slowly passed, the chakra sphere surrounding Uchiha Arata began to shrink, signaling that the fusion of the bloodline had entered its final stage.
Gradually, the sphere contracted—from five meters, to four, then three, and finally two. As it continued to diminish, Arata's figure slowly reappeared within the fading glow.
Yet as the sky-blue chakra sphere shrank, a soft green radiance began to bloom from Arata's body.
As that green light grew brighter, it completely overwhelmed the remaining blue chakra, washing over the surrounding space like a living tide.
The green glow intensified further and further.
Under its illumination, the wooden structure Arata had constructed using Wood Release seemed to awaken.
Wherever the light reached, tiny green sprouts broke through surfaces, rapidly growing and spreading as though someone were actively accelerating their growth with Wood Release.
Time passed without notice.
When Arata finally opened his eyes, he found that the once-empty sealed chamber had been completely overtaken by thick vines and creeping vegetation, nearly filling the entire room.
He showed no surprise.
Arata immediately understood.....his vitality had become so vast that a portion of it had leaked outward, unconsciously stimulating the surrounding environment.
Rather than leaving the space immediately, Arata stepped out of the sealed chamber and ascended to the highest point of the island.
There, he began testing his transformed body.
For a time, the entire island echoed with thunderous booms.
Trees surged upward at unnatural speeds, accompanied by the creaking and cracking sounds of rapid growth.
Only after a long while did Arata finally stop.
The results were clear.
After fusing the Uzumaki bloodline and physique, his life force and chakra reserves had undergone a fundamental transformation.
Because Arata's chakra had already been astonishingly vast, the Uzumaki bloodline increased it by "only" about three times.
However, his life force was a different matter.
It had increased by six to seven times.
This was especially terrifying considering that Arata had already fused Yamato's Wood Release, which had long granted him vitality far beyond that of ordinary shinobi.
By conservative estimates, Arata's current chakra reserves and life force were now hundreds of times greater than those of a standard jōnin.
Even more surprising was that after gaining the Uzumaki bloodline, the power of his Wood Release had increased dramatically.
While it still fell short of Senju Hashirama, it far surpassed anything Yamato could achieve.
Additionally, whether because the Uzumaki bloodline helped complete parts of the Sage Body, or because his flesh had been repeatedly torn apart and regenerated during the fusion, Arata's physical strength had increased to an extraordinary degree.
More than that, Arata could clearly feel that since fusing the Uzumaki bloodline, his eyes felt as though they had been immersed in a warm spring.....gentle, nourishing, and alive.
It was obvious that the strengthening of his body had also benefited his Eternal Mangekyō Sharingan.
At that moment, the system's voice sounded:
"Congratulations, Host. Due to the further completion of the Sage Body and the strengthening of the physical vessel, the cooldown of the ocular technique 'Kotoamatsukami' has been significantly reduced. Estimated remaining cooldown: three days."
Arata blinked in surprise.
If he had known earlier, he would have used Izanagi first.
Standing atop the island's peak, Arata gazed into the distance and stretched lazily.
His body released a series of crisp cracking sounds, leaving him feeling extraordinarily refreshed.
Soon after, Arata realized that by integrating the Uzumaki bloodline, he had also awakened the clan's innate abilities.
Uzumaki Bloodline Talents
1. Sensory Ability — Kagura's Mind Eye
Arata could now sense chakra within a radius of dozens of kilometers, accurately perceiving both presence and quantity. With sufficient familiarity, he could even identify individuals.
Thanks to his overwhelming mental strength, he could also determine whether someone was lying based on subtle fluctuations in their chakra.
2. Regenerative Ability — Vitality Healing
Like Uzumaki Xianglin and Karin, Arata could allow others to recover chakra and injuries by biting his flesh.
However, for Arata himself, this ability was largely redundant—his own vitality was already so immense that he could regenerate injuries rapidly without assistance.
By the time Arata finally exited the space, it was already deep into the night.
He hadn't expected to remain inside for so long.....but it was worth it.
After fully fusing the Uzumaki bloodline, his strength had advanced yet again.
