Ch.264 Kōryūgan

The most immediate sensation Uchiha Shinji felt was that these crimson eyes possessed an extraordinarily strong perception ability, comparable to the Byakugan he had obtained from the Ōtsutsuki branch family.

It was important to note that not all dojutsu-based Bloodline Limits had x-ray vision.

Therefore, the ability of these crimson eyes to perceive through objects was likely inherited from the enhanced version of the Hogan, and it had even surpassed its predecessor.

Moreover, these eyes seemed to have a special insight into blood.

Switching to the perspective of his crimson eyes, Shinji looked down at his own body and found that his veins and blood flow were visible down to the finest details.

"A perfect inheritance of the fundamental abilities of the Ketsuryūgan and Hogan, huh..."

Muttering to himself, Shinji approached a pool of water inside the cave. Through the reflection on the water's surface, he carefully examined the appearance of his new dojutsu.

These crimson eyes had a gemstone-like texture.

The signature horizontal slit of the Ketsuryūgan was gone, replaced by a black rhombus pattern in the center of the pupil. The combination of a red sclera and black pupil gave off an eerie and indescribable aura!

Gazing into these eyes, filled with an overwhelming presence of ocular power, Shinji felt a surge of emotions. "I actually created an entirely new dojutsu-based Bloodline Limit!"

It took him a long moment to calm himself.

Then, he slowly activated his dojutsu, exploring the possible abilities contained within these crimson eyes.

In his view, an eye with such a high level of ocular power was almost certain to contain a unique dojutsu.

However, after multiple attempts, he found nothing.

No, it wasn't entirely fruitless. At the very least, he confirmed that these eyes did indeed hold a special dojutsu—it was just that he couldn't use it yet.

The reason was simple!

Even though Shinji was the one who created these crimson eyes, he was neither of the Hogan Clan nor of the Blood Pond Clan. His bloodline had no direct connection to these eyes.

Furthermore, Shinji did not possess high-quality Yang Release chakra to nourish or awaken these eyes.

As a result, his compatibility with these crimson eyes was low.

But this wouldn't have been a problem if these eyes were at a lower tier. After all, they were forcibly fused together by Shinji using the Susanoo Tomoshibi, so compatibility shouldn't have mattered.

The issue was that these eyes had turned out to be far stronger than Shinji initially expected.

This meant that while their ocular power didn't surpass his Eternal Mangekyō Sharingan, they were strong enough to resist its influence. So, as Shinji tried to control them using Susanoo Tomoshibi, they, in turn, resisted him with their own power.

Understanding this, Shinji ceased his experiments.

To solve this problem, he considered two methods.

The first was to transplant these crimson eyes and slowly develop their potential through prolonged nourishment and adaptation.

Nagato, for instance, took decades of meticulous development to go from being unable to use the Rinnegan to eventually mastering nearly all of its abilities.

Apart from the unique space-time dojutsu of the Rinnegan, Limbo: Border Jail, Nagato had managed to discover and use every other Rinnegan technique through sheer effort.

The second method was to further enhance his own Eternal Mangekyō Sharingan's power to the point where it could completely suppress these crimson eyes. Then, using Susanoo Tomoshibi, he could forcibly extract and master their hidden abilities.

As long as his Eternal Mangekyō Sharingan was strong enough, he could wring out every last drop of power from these crimson eyes.

One method was gradual and orthodox. The other was forceful and domineering.

Both methods were viable, but both required time—they could not be achieved overnight.

After weighing his options, Shinji chuckled softly.

His original goal had merely been to create a dojutsu-based Bloodline Limit different from the Sharingan and Byakugan, so he could enhance his own ocular power through Susanoo Tomoshibi.

Now, he had far exceeded that goal—so what was there to hesitate about?

As for the special dojutsu within these crimson eyes, Shinji wasn't in dire need of it. His number of active dojutsu slots was limited.

For this new dojutsu to be useful, it would have to surpass Amaterasu, Izanagi-no-Mikoto, Susanoo, and other high-level Mangekyō techniques.

Otherwise, it would have no choice but to sit on the bench.

Whether this new ability was stronger than Amaterasu or Izanagi-no-Mikoto, even Shinji couldn't say for sure.

Gathering his thoughts, Shinji smiled. "To think something I created could be so defiant... In that case, I'll name you Kōryūgan!"

Although he had only used these crimson eyes for a short while, Shinji had already sensed their personality. If he had to describe them in one word, it would be unruly—a defiance so strong that even their creator could not subdue them!

So, on a whim, he bestowed upon them the name Kōryūgan.

From this moment onward, the shinobi world had gained a new dojutsu-based Bloodline Limit—the Kōryūgan!

Shinji did not linger outside any longer. After briefly recovering his strength, he immediately set off back to the Hidden Leaf.

Once he successfully returned to his apartment and sent Coalball away, he finally collapsed onto his bed, completely relaxing for the first time.

As soon as he let go, exhaustion surged over him like a tidal wave, making it difficult to even keep his eyes open.

Only now did he truly realize just how much ocular power he had expended in forcibly merging the Kōryūgan.

After a deep sleep, he finally regained his energy the next day.

However, despite a full night's rest, he still felt occasional stinging pain in his Eternal Mangekyō Sharingan.

"It looks like I'll need at least a few more days to fully recover."

Shaking his head, Shinji made his way to the academy.

As usual, the moment he arrived, he found Shion and supervised her morning training.

After some time, Shion walked up to him, scrutinizing him carefully before asking, "Shinji, what did you do last night?"

Shinji glanced at her indifferently. "Why?"

Shion furrowed her brows. "You look really tired."

Shinji's heart tensed slightly. Her chakra quality has noticeably improved.

Before leaving home, he had checked himself in the mirror—his face showed no visible signs of fatigue. His exhaustion was spiritual, a depletion of ocular power, which was something most people wouldn't be able to detect.

The fact that Shion could sense it meant only one thing—her chakra had grown even stronger.

As they continued chatting, their conversation shifted toward Naruto.

Scanning the academy grounds, Shion pouted. "Where the heck has Naruto been these past few days? I was worried Sasuke abandoned him, but he just vanished from school entirely!"
