Eyes

"Uchiha Madara, although it's a bit questionable to fight an elderly person, if it allows me to witness the prowess of the top power from the previous era, it's still worth considering. Hopefully, I can face him when the time comes."

Kirito isn't one to dawdle; he promptly sets his sights on capturing Indra's Chakra from Uchiha Madara.

While Uchiha Madara is formidable, with Kirito mastering the Sage Mode, acquiring potent ninjutsu and senjutsu, along with support from a skilled team, facing Madara's ultimate form in his old age should be feasible.

"Next, let's see how Sage Mode affects Byakugan."

With the objective of capturing Indra's Chakra set, Kirito redirects his attention to the Byakugan.

Today's tests for Byakugan focus on two aspects: the influence of Mokuton Chakra and the effects of Sage Chakra.

Zetsu, unlike Kirito's main body, has lesser aptitude for Sage Arts. However, due to the divine tree cells and Hashirama cells, it possesses excellent abilities to sense and absorb natural energy.

Leveraging experience in condensing Sage Chakra from the main body, Zetsu's clone successfully produces Sage Chakra.

Unlike Kirito's main body needing the Yin Seal, Zetsu's clone, with its abundant chakra and natural energy conversion ability, enters Sage Mode without opening the seal, albeit taking slightly longer.

After about 3 minutes, Zetsu's clone successfully enters Sage Mode.

However, Zetsu's Sage Mode appearance lacks the finesse of Kirito's main body; it manifests a simplified version akin to Hashirama senjutsu mode, yet its authentic Sage Chakra emanates from its body.

Sage Chakra's allure surpasses even Mokuton Chakra's appeal.

Zetsu's clone eyes eagerly absorbs the Sage Chakra, demonstrating a clear preference for it over Mokuton Chakra.

With Byakugan nourished by Sage Arts, its appearance changes significantly. The noble purple hue intensifies, and the pupils become more pronounced, edged with a hint of red and deep blue.

Kirito then injects a substantial amount of Sage Chakra into the Byakugan, activating it.

Sage Technique: White Eyes.

Empowered by Sage Arts, the Byakugan's abilities are markedly enhanced, expanding its detection range and improving dynamic vision.

From eleven kilometers away, Kirito clearly observes a mosquito's movements as if viewing a slowed-down video.

This enhanced vision makes sneak attacks nearly impossible against a Byakugan user, forcing foes into direct confrontation.

Moreover, his Byakugan's gaze carries a subtle mental pressure, evident even to Kirito with his heightened soul power, indicating its formidable spiritual coercion.

It remind him of kaguya eyes.

Kirito acknowledges The Byakugan's potential, comparing it favorably to the Sharingan's Blood Limit.

There is no trash ability, only trash user.

This revelation sparks Kirito's eagerness to test the Byakugan's newfound abilities in combat, particularly during an upcoming interaction with iwagakure.

Excitement gleams in Kirito's eyes as he anticipates the opportunities ahead.

These days, Kirito has gained a good understanding of the root and sunagakure activities in the Land of Rain, thanks to the intelligence network established by the Night Organization in that region. So far, he has identified two suspected members of the Skull Squad and traces of Chiyo.

It's expected that on the day of his deal with iwagakure, there will be an epic battle, with numerous forces likely joining the fray.

The zetsu clone closed the Byakugan and stored the remaining Sage Chakra in the sub-pool newly opened by the Yin Seal within its body.

Due to his high chakra reserves and the rapid conversion of natural energy into chakra, the secondary pool within Bai Juefen's body stores more Sage Chakra than the main body, although it's still far from being fully filled.

This process is estimated to take at least a month.

By then, the zetsu avatar will sustain the Byakugan with the Sage chakra from the secondary pool, facilitating its evolution alongside with the Wood Chakra.

Following the testing of the byakugan, the next natural step is to assess the Blood eyes

Kirito's anticipation for Blood Dragon Eye isn't as high as for the Byakugan, given that it's not linked to otsutsuki. However, its blood-manipulating abilities spark his curiosity and expectations.

Blood is crucial for life, constituting genetic information carried by the cells. In essence, the Blood limite Boundary is a form of genetic information.

Considering this link, Kirito contemplates whether Blood Dragon Eye's blood manipulation could extend to genetic information control.

If realized, he might mass-produce Bloodlin ninjas by activating the genetic potential of those with Blood Successor Limit potential, granting them this power.

This idea fuels Kirito's belief that Blood dragon eyes potential can impact the limits of Blood Successor Boundaries.

Kirito then prepares for the eye transplant operation, lying on the operating table as his zetsu avatar takes charge.

The clone skillfully removes Kirito's eyeballs and then transplants the two Blood Dragon Eyes.

Upon awakening, Kirito feels intense rejection from the Blood Dragon Eyes, experiencing soreness, blurred vision, and blood-filled eyes.

"This is quite painful. Unlike My zetsu avatar with the Byakugan, this bloodline rejection is severe. It seems like this bloodline eyes doesn't align well with mine, making it challenging for me to utilize," Kirito remarks, noting the struggle.

However, he has a solution—relying on his Sage Chakra. This potent and aggressive chakra, akin to Juugo chakra, can infect and empower beings, similar to the Kirito-style curse-seal technique he devised, born from the idea of Orochimaru's future seals.

Kirito begins condensing his Sage Chakra to counter the rejection and strengthen his control over the Blood Dragon Eye's power.

Kirito swiftly generated a steady stream of Sage Chakra and directed it towards the Blood Dragon Eyes.

Just like the White Eyes before, the Blood Dragon Eyes craved chakra, especially the advanced forme of sage Chakra. Unsurprisingly, it welcomed the infusion of the sage Chakra eagerly, inhaling it with delight.

As Kirito's will-infused Sage Chakra entered the Blood Dragon Eyes, an immediate transformation occurred. The whites of the eyes, originally blood-colored, gradually turned black, while the straight-lined white pupils shifted to a deep purple hue.

Simultaneously, the intense rejection Kirito had been experiencing due to his lack of fitting bloodline rapidly diminished. His vision cleared, and he gained increasing control over the blood eyes.

Continued infusion of Sage Chakra reduced the rejection even further until Kirito felt no rejection at all from the Blood Dragon Eyes. It was as if they were his original eyes, completely controllable without discomfort.

Moreover, the strain on his body caused by the Blood Dragon Eyes vanished. The continuous chakra absorption and consumption also ceased, eliminating concerns of depleting chakra like Kakashi's Sharingan in the original story.

With a mental command, the Blood Dragon Eyes smoothly closed and returned to a normal state, a relief for Kirito.

"Phew, thankfully my eyes are naturally black. Otherwise, I'd have to wear colored contacts every day to conceal this," Kirito remarked, looking at his normal-looking eyes through Baijue's avatar's vision.

The successful concealment of the Blood Dragon Eyes was crucial for Kirito. He saw them as a hidden advantage in ninja battles, akin to his Spirit Transformation Technique. However, he decided to further conceal them with specialized goggles that completely covered the eyes.

Thinking ahead, Kirito considered the potential of the Blood Dragon Eyes, now nourished by Sage Chakra. Although their abilities improved, being stored for long periods had weakened their vitality and agility.

Drawing from the Byakugan abilities, Kirito merged the zetsu's avatar into his body using the spore techniques, then infused the Wood Chakra into himself. This chakra, aggressive like his Sage Chakra, was suppressed and wrapped by his Senjutsu Chakra once in his main body, then coerced into the Blood Dragon Eyes.

Under Kirito's control, the Blood Dragon Eyes absorbed both sage Chakra and Wood Chakra without resistance. This revitalized them, making their previously dull appearance lively and bright.

Moreover, a unique blood-red Yin Chakra began forming in the Blood Dragon Eyes. As it flowed through Kirito's body, it absorbed and transformed the original Yin Chakra into this special form.

This new Yin Chakra granted Kirito an enhanced perception ability—blood perception.

He didn't rely on soul perception or natural energy perception. Instead, he tapped into his new blood perception ability. At that moment, he could distinctly sense the orphanage and numerous creatures within hundreds of meters around him. Through the flow of blood in these creatures, he could pinpoint their locations with precision. What's more, he felt he could potentially manipulate their blood.

"This special Yin Chakra truly embodies the essence of the Blood Dragon Eyes. It absorbs my chakra, giving rise to its own unique energy. It's almost like a mystical form of bloodline limit."

Observing the process through the zetsu clone's Byakugan, Kirito marveled at the development of this unique Yin Chakra.

Eager to test the newfound powers of the Blood Dragon Eyes, Kirito began his experiments.

The first step was to absorb Sage Chakra to activate the eyes.

Kirito swiftly infused a large amount of Wood Chakra into the Blood Dragon Eye, successfully opening it.

This time, the Blood Dragon Eye opened normally, without being influenced by the Sage Chakra.

Upon opening the Blood Dragon Eye, Kirito noticed a significant enhancement in his blood perception ability. The range expanded from 300 meters to thousands of meters.

Without delay, he instructed his clone to open its White Eyes, using them to lock onto a chakra-infused venomous snake hundreds of meters away.

This particular snake had evolved into a ninja beast, evident from its large size akin to a basketball.

It was the first time Kirito had spotted such a sizable venomous snake in the forest. Currently, it was hiding underground in a snake hole after having a full meal.

Selecting this target to test the Blood Dragon Eye's abilities, Kirito activated its blood manipulation power.

Instantly, through the Byakugan, he witnessed the venomous snake convulsing and blood streaming from its eyes, ears, mouth, and nose.

"Is this the Blood Dragon Eye's blood manipulation ability? It's a potent weapon on the battlefield. Even without causing external wounds, it can silently kill foes by inducing sudden blood surges," Kirito remarked, impressed by the gruesome effects.

Moving forward, he replaced the Wood Chakra with Sage Chakra to reopen the Blood Dragon Eyes.

With the infusion of Sage Chakra, the Blood Dragon Eyes reverted to their original state before being influenced by Sage Chakra, with black whites and purple pupils.

Now empowered by Sage Chakra, the blood perception extended to two kilometers, and blood control became even more precise. Kirito proceeded to test it again on the venomous snake, causing its body to rupture instantly.

Utilizing the Sage Chakra, Kirito demonstrated the Blood Dragon Eye's ability to lethally strike a formidable ninja-level creature from several hundred meters away.

"Indeed, bolstered by sage Chakra, the Blood Dragon Eye possesses the capability to instantly dispatch weak ninjas, especially suitable for long-range assassinations," kirito noted, observing the snake's demise through his Zetsu's clone's White Eyes, expressing satisfaction.

Meanwhile, outside the village, Orochimaru paused in his dissecting activities, turned towards the orphanage's direction, and voiced his confusion, "Dead? How did they meet their end?".
