Three Spinning Hooks, Two Tomoe Plus?

Uchiha Kazuhiko took a deep breath, forcing himself to calm down.

"I am a genius! My logical chain is crystal clear!"

Analyzing from a rational perspective:

As an Uchiha, the entry with the highest priority right now is undoubtedly the Two-Tomoe Sharingan.

It provides the greatest boost to my strength and genjutsu, and it will also be very helpful for my upcoming eye-opening plan.

"Therefore, the first entry I will attempt is..."

[Replace Entry: Sharingan: Single Tomoe (Green)]

[Equip Entry: Phantom Body Flicker - Body Flicker Shisui Exclusive (Purple)]

[Permanent Condition: Master the Body Flicker Technique. Awaken the Three-Tomoe Sharingan. In a normal state, be able to sustain multiple physical illusions (ten or more) for a long period.]

[Chakra Level: 0.8 Kak]--[Chakra Level: 0.7 Kak]

Kazuhiko ignored the temporary changes to his panel, focusing his attention on the new favorite entry.

"This permanent condition..." It was incomprehensible.

How long is "a long period"?

What conditions are required to "sustain ten or more physical illusions"?

If it were just using the Body Flicker Technique to leave behind an afterimage, any ninja could do it; it was as easy as breathing.

After all, the Body Flicker Technique was a mandatory course for every ninja graduate; one couldn't even graduate without mastering it.

Calculating based on Kazuhiko's current chakra levels, the total distance he could cover by continuously using the Body Flicker Technique would be enough to circle Konoha three times, and the illusions produced would be enough to surround the entire village.

Kazuhiko successfully equipped the entry, and [Phantom Body Flicker] was refined in an instant.

Memories and experiences related to the Phantom Body Flicker technique suddenly flooded his mind.

This experience, naturally, came from the number one genius, Body Flicker Shisui.

The next moment—

On the bed, the floor, the ceiling, the windows... the entire bedroom was filled with figures; dozens of Uchiha Kazuhiko appeared in the room simultaneously.

Before he could take the next step—

All the Kazuhikos bent over in unison, sweat beading on their foreheads. The man looked as if he had been fished out of water, his clothes soaked through with cold sweat.

All the phantom Kazuhikos vanished, leaving only the real one collapsed on the bed, gasping for air.

Exhausted—it felt like pulling an all-nighter, followed by 48 hours of overtime.

At this moment, Kazuhiko didn't even want to move a single finger.

Just now, casting ten Phantom Body Flickers made him feel as if he hadn't just used a ninjutsu, but had completed a triathlon in a few seconds; his body was truly hollowed out.

In less than three seconds, Kazuhiko had completely collapsed from exhaustion.

This made him start to doubt the entry's permanent condition.

"Sustaining 10 Body Flicker illusions for a long time clearly requires the stamina of a superman. Is this something a human can actually do?"

Thinking of how Shisui used the Phantom Body Flicker, Kazuhiko gritted his teeth.

"Fine, so you were a physical-stat cheater all along!"

Starting today, it's time to hit the gym!

[Replace Entry: Phantom Body Flicker - Body Flicker Shisui Exclusive (Purple)]

[Equip Entry: Two-Tomoe Sharingan (Blue)]

[Permanent Condition: Master the Sharingan's abilities, successfully copy one B-rank ninjutsu]

[Chakra Level +0.2]--[Chakra Level: 0.9 Kak]

The entry was equipped successfully, and the familiar burning sensation struck again, causing Kazuhiko's pupils to tremble violently as tears streamed down his face.

Pain!

A searing, fiery pain!

He knew clearly that this was his eyes undergoing a baptism of ocular power, about to break out of their cocoon!

The next moment, the sensation of flames burning in his eyes faded, and two tomoe slowly rotated within them.

The surging ocular power made Kazuhiko's vision incredibly clear, and even his depleted stamina recovered significantly due to the implicit benefits brought by the Sharingan.

"As expected, the Sharingan is better suited for an Uchiha baby's constitution!"

Kazuhiko felt as if he had come back to life, his breathing slowly beginning to steady.

He immediately thought of a question:

"If I equip both the Single Tomoe and the Two-Tomoe at the same time, what will happen to my Sharingan?"

"Conflict? Stacking? Or will it be a Two-Tomoe Plus with three tomoe spinning around?"

[Replace Entry: Strongest Genius Eye Power (Purple)]

[Equipped Entry: Sharingan: Single Tomoe (Green)]

[Equipped Entries (2/2): Sharingan: Single Tomoe (Green), Three-Tomoe Sharingan (Blue)]

[Chakra Level: 0.9 Ka]--[Chakra Level: 0.85 Ka]

Before Kazuhiko could examine the changes to his Sharingan, an anomaly suddenly occurred!

Deep Blue suddenly erupted with blinding light, the streams of light from the two Sharingan entries intertwining and wrapping around each other.

The green and blue entries resembled two fish chasing one another, their heads and tails merging.

[Equipped similar entries, fusion conditions met]

[Entry fusion initiated...]

Kazuhiko narrowed his eyes.

Fusion?!

The two streams of light finally became indistinguishable, transforming into an even more brilliant radiance.

[Entry fusion successful--]

As the light faded, a brand-new entry hovered within his sea of consciousness--

[Sharingan: Perfect Double Tomoe (Deep Blue)]

[Description: The fused and advanced Sharingan is even more powerful. Dynamic vision, genjutsu amplification, copying ability, and hypnotic ability are all-around enhanced. Capable of copying high-level ninjutsu and seeing through mid-to-high-level genjutsu.]

[Evaluation: A perfect double-tomoe Sharingan; there is no need to fear even a three-tomoe.]

[Chakra Level +0.1 Ka]--[Chakra Level: 0.95 Ka]

Soon, the anomaly vanished, and Kazuhiko's vision returned to normal.

"Rivaling a Three-Tomoe Sharingan..."

The increase in eye power made his field of vision much clearer.

Observing his reflection in the glass, he discovered that the tomoe in the center of his pupils had become more solid.

The two tomoe were perfectly symmetrical, giving off a sense of "perfection," as if this were the ultimate form of the Sharingan.

Deep Blue's notification arrived once more:

[Unlocked hidden function: Entry Fusion Advancement]

[Similar entries can be fused together; after fusion, quality increases and effects become more powerful.]

Kazuhiko let out a long breath.

If you could do this, you should have said so earlier!

He immediately scanned all his entries, searching for combinations that might meet the fusion criteria--

[Equipped Entries (2/2): Sharingan: Perfect Double Tomoe, Strongest Genius Eye Power: Shisui Exclusive]

The two entries showed no signs of fusing.

"Rationally speaking, these two entries should definitely be able to fuse; after all, they both originate from Shisui."

Could it be that the double-tomoe Sharingan isn't qualified enough?

That is highly likely, given that the permanent condition for the strongest eye power is to unlock the Three-Tomoe Sharingan.

A perfect double-tomoe is still just a double-tomoe.

Kazuhiko shook his head and looked for other permutations and combinations.

[Equipped Entries (2/2): Taijutsu: Konoha Style Taijutsu (Green), Uchiha Style Taijutsu (Green)]

[Equipped similar entries, fusing...]

It really could fuse!

It was no surprise that Uchiha and Konoha Style Taijutsu could fuse, as they shared a common origin.

[Entry fusion successful--]

[Taijutsu: Uchiha-Konoha Style Mastery (Deep Green)]

[Description: You have integrated Konoha and Uchiha style taijutsu, combining the strengths of both. Your speed, strikes, and taijutsu power will be even more astonishing.]

[Permanent Condition: Master basic taijutsu, proficiently master Uchiha Style Taijutsu and Konoha Style Taijutsu.]

Continue!

[Equipped Entries (2/2): Shurikenjutsu (Green), Ninja Tool Throwing Mastery (Green)]

[...]

[Fusion successful--]

[Hidden Weapon Master (Deep Green)]

[Description: Kunai, shuriken, senbon, and other weapons are the deadliest tools in your hands. You can manipulate ninja tools at will via chakra threads, killing invisibly.]

"Fusion advancement..."

Kazuhiko muttered to himself, his eyes gleaming with excitement.

The fusion advancement of entries allowed even those originally useless entries a chance to turn waste into treasure, becoming rare entries worthy of permanent equipment.

Entry fusion represented infinite possibilities.

"Time to try other entries!"
