Kirigakure's Red Eye

Ignoring the comedic speeds and exaggerated depictions of speed found in the manga, A normal ninja maneuvering through trees (constantly using chakra to jump) can reach a speed of 20 meters per second in regular combat (PS: refer to the ninja tree-walking guide), which is 72 km per hour.

This speed can be further increased with chakra augmentation. For example, the Body Flicker Technique can exceed the speed of sound in an instant. However, at such speeds, the eyesight of ordinary ninja struggles to keep up.

Ninja who lack dynamic vision, or who haven't undergone specialized training in fighting and controlling their bodies at such high speeds, will be exploited for openings if they rashly exceed their controllable speed. They'll be finished off with a single kunai.

But even so, This is still a displacement speed far exceeding that of the sprint champions from Hyuga Yu's previous life.

At this moment, The surging wind whipped past his cheeks, and the hair at his temples and behind his ears flew backward with the wind's trajectory.

In just about an hour, Hyuga Yu had covered nearly a hundred kilometers, passing through the Konoha training grounds and the Forest of Death, arriving at an unnamed forest on the east side of Konoha Village.

Continuing at full speed for another four hours would bring him to Grass Wave Coast, But now, Hyuga Yu stopped in a clearing within the forest.

"Hoo... hoo..."

He took two deep breaths, and while adjusting his breathing, he took a Military Rations Pill from the ninja tool pouch on his lower back and popped it into his mouth.

Although his chakra was scarce, only about the level of a typical Chunin (half the amount of young Hinata), this amount of chakra was sufficient to support Hyuga Yu running at full speed for over 3 hours.

The reason he stopped now was not due to insufficient chakra, But rather, He felt a sense of "being watched"!

Sensory ninja can perceive each other. For instance, during Sasuke's rampage at the Kage Summit, Kumogakure ninja Karin and the Leaf ninja Karin perceived each other's presence. Karin, relying on her Mind's Eye of the Kagura, directly pinpointed Karin's location, while Karin needed some time to carefully sense and confirm Karin's position.

(PS: This excludes sensory abilities not driven by chakra. For example, between Byakugan and ordinary sensory ninja, a Byakugan user can see the other person and sense their perception of them via chakra. However, ordinary sensory ninja cannot detect a Byakugan user's gaze falling upon them from over a kilometer away. The Inuzuka clan's sense of smell works similarly.)

For Hyuga Yu, who was more sensitive than ordinary sensory ninja and could even feel the abstract sensation of "gaze," this feeling of being watched was no less jarring than someone suddenly pulling down his pants and throwing an alligator inside.

Hyuga Yu immediately tilted his head slightly, the veins around his eyes bulging, "Byakugan, activate!"

A divine perspective, expanding instantaneously, covered a one-kilometer radius. At a fork in the forest path about a kilometer away, As expected, Hyuga Yu saw a squad of Kirigakure ninja.

This squad consisted of a Jonin with sensory ninjutsu, a "strange" Chunin, and a Genin who made him feel slightly "uncomfortable."

As for how Hyuga Yu distinguished their ranks?

It wasn't difficult.

The distinction between Chunin and Genin was based on whether they wore the village-issued Chunin vest. Kirigakure's vests were a more stylish gray, laced plate armor compared to Konoha's.

The distinction between a Chunin wearing a vest and a Jonin was based on their shoes...

Although Hyuga Yu didn't understand why there was such a peculiar custom in the Naruto world, normally, ninja boots worn by Chunin and Genin had their heels covered, while Jonin's boots had exposed heels.

Furthermore, A ninja who could sense him from beyond the perception range of a Hyuga Clan ninja like Hyuga Yu had mastered sensory ninjutsu to the limits of conventional ninja, at least reaching the level of a Special Jonin.

At this moment, At this wrong time and wrong place, the reactions of both sides, having sensed each other, differed.

Hyuga Yu immediately put on an expression of "shocked astonishment," his body trembling slightly, and he "couldn't help" but take two steps back, appearing as if he wanted to flee immediately.

On the other side, The Kirigakure Jonin who sensed Hyuga Yu also showed surprise, "Wait, where did this brat come from?"

Beside him, the "strange" Chunin asked in a deep voice, "Kensuke, what's the situation?"

"Ao-sama, we've discovered a Hyuga Clan ninja. His chakra fluctuations are very weak, like a graduate from the Ninja Academy."

Ao immediately frowned, "A Hyuga Clan member?"

The Kirigakure Jonin Kensuke quickly reported, "Yes. Using his Byakugan, he's also discovered us. It seems... he's trying to run?"

Ao began to ponder.

He had set up a funnel-shaped encirclement for the hunt of the Hyuga Main Family.

However, their squad wasn't a vanguard meant to deceive the enemy, but a core team composed of three skilled sensory ninja, tasked with pinpointing the location of the Hyuga Main Family and carrying out the capture.

Now, An unexpected Hyuga Genin passing by had stumbled upon them.

If they deliberately pursued him, it would delay their plan. If they let him run towards Konoha, he would inevitably encounter the Hyuga Main Family's group, causing a leak in the intelligence for the capture plan.

In that case, the first "bait" to appear before the Hyuga Main Family's group might lose its effectiveness--

If the Hyuga Main Family detected more than two Kirigakure Ninja on the route, they would surely become wary. Upon seeing the decoy team positioned at the "horn tail," they would likely see through the entire plan and immediately abandon the mission to return to Konoha.

Thinking this, Ao couldn't help but feel a slight headache. He immediately turned his head slightly to look at the Genin beside him, who only came up to his waist.

"Kurenai, can you handle this brat?"

The Genin being addressed was a boy with purple hair, about twelve or thirteen years old. A black cloth was covering his eyes. After hearing Ao's inquiry, he was silent for a moment before replying:

"Yes."

"But the Hyuga Main Family is almost here."

Ao immediately ordered, "Then use your Red Eye to create a Chakra image within the Byakugan's field of vision, making him see that we have 'avoided' him."

"Let this Hyuga brat continue forward."

"Wait until he's close, then you confirm his identity and determine if this was truly just an accident!"

"Understood." The boy with black cloth over his eyes nodded, slowly raised his hands, and untied the black cloth from behind his head, revealing a pair of amber pupils.

The next moment, these pupils were stained with blood, turning a fiery red!

The boy slightly raised his head, looking in the direction of Hyuga Yu. An invisible pupil power began to spread along the visual range that both parties could perceive, expanding and distorting, and then, manipulating the content of the vision, a Kekkei Genkai known as "Byakugan."

Meanwhile, Upon seeing the formation of this Kirigakure Ninja squad, Hyuga Yu's heart also couldn't help but tremble.

Aside from the Jonin who could sense him despite his Byakugan, the "strange" Chunin looked more and more familiar the longer he looked. After pondering for a while, he suddenly realized, Isn't this the Ninja that Kirigakure sent this time to hunt down the Main Family, capture the Byakugan, and finally transplant it onto himself?

Ao!

Damn it, a dignified Jonin is actually disguised as a Chunin, have they no shame!

But in the very next moment, Hyuga Yu suppressed his surprise at running into the enemy BOSS, because he saw something even more chilling to the Hyuga--

The Genin standing next to Ao, after removing his blindfold, actually opened a pair of pupils known as "Red Eye"!

No,

Hyuga Yu subconsciously swallowed, he was starting to panic now.

Damn it, entering the BOSS room early is one thing, but how does this BOSS have a "special weapon" specifically designed to counter me?
