As soon as Bai Ye's voice fell, he observed the Three Tomoe Sharingan lying motionless in a liquid-filled container before him. Slowly, it began to fade away.
At the same time, the One Tomoe Sharingan appeared in Bai Ye's personal status template. His once-black eyes now displayed the distinctive single-tomoe pattern of the Sharingan.
"So, this is the Sharingan?"
Bai Ye opened his eyes and looked around.
His vision felt slightly sharper—an improvement, albeit subtle, but undeniably real.
Then, a system prompt appeared:
[Detected: The Host currently possesses both the 'Mystic Eyes of Death Perception' and 'One Tomoe Sharingan.']
[Would you like to fuse the One Tomoe Sharingan with the Mystic Eyes of Death Perception?]
[Hint: Fusion will grant slight resistance to illusions and enhance visual perception.]
"Fusion?"
Bai Ye gazed at his reflection in Ryūjin Jakka's blade, deep in thought.
"Because the 'Mystic Eyes of Death Perception' are far superior to the One Tomoe Sharingan, the latter would essentially be absorbed as nourishment rather than an equal fusion?"
Given the Sharingan's lower rank, it wasn't worthy of being placed alongside the Rainbow-Level Mystic Eyes of Death Perception. However, Bai Ye chose not to fuse them just yet.
A single One Tomoe Sharingan might not add much power—but what about two? Three?
What if he combined all the One Tomoe and Two Tomoe Sharingan in front of him into a single pair of eyes?
Unlike others who could only acquire a fixed-level Sharingan through transplantation, Bai Ye had a unique advantage.
Even Danzo, who implanted multiple Sharingan, could only increase their quantity—not their quality.
Bai Ye, however, could integrate them into his template—turning multiple single and double-tomoe Sharingan into a single, superior pair!
With that in mind, Bai Ye began placing his hands over each container holding a Sharingan.
One by one, they were absorbed.
Before long:
[Your One Tomoe Sharingan has fused with another One Tomoe Sharingan.]
[Your One Tomoe Sharingan has undergone a special transformation...]
[Your One Tomoe Sharingan has evolved into a Two Tomoe Sharingan!]
"It works!"
A glint of excitement flashed in Bai Ye's eyes.
He continued the process:
[Your Two Tomoe Sharingan has fused with a One Tomoe Sharingan.]
[Your Two Tomoe Sharingan has fused with another Two Tomoe Sharingan.]
[Your Two Tomoe Sharingan has evolved into a Three Tomoe Sharingan!]
This cycle repeated countless times within the underground base.
Until finally:
[Ding! Your Three Tomoe Sharingan has fused with another Two Tomoe Sharingan.]
[Your Three Tomoe Sharingan has officially evolved into the Mangekyō Sharingan!]
[Your Mangekyō Sharingan has fused with another Two Tomoe Sharingan.]
[Your Mangekyō Sharingan has automatically evolved into the Eternal Mangekyō Sharingan!]
With the last Two Tomoe Sharingan absorbed, Bai Ye slowly opened his eyes.
Complex scarlet patterns formed in his once-black irises.
His Sharingan had now evolved into the Mangekyō Sharingan—and not just any Mangekyō.
The Eternal Mangekyō Sharingan!
For the Uchiha clan, this level of power could only be achieved through transplanting a blood relative's eyes.
Yet, Bai Ye had attained it without a single drop of Uchiha blood.
Any witness would be utterly shocked.
This was the power of Bai Ye's Shinigami template—a core ability that allowed him to integrate the strengths of different worlds.
As long as the abilities were based on Shinigami spiritual energy, Bai Ye could use them freely.
Moreover, since his Eternal Mangekyō Sharingan was created by fusing a vast number of One Tomoe and Two Tomoe Sharingan, he wasn't limited to just one or two Mangekyō abilities.
He could wield Amaterasu, Tsukuyomi, Susanoo—all of them!
However, there was one small disappointment—none of the absorbed eyes contained the Kamui Space ability.
Even so, this was an enormous win for Bai Ye.
He had just arrived in the Naruto world, and Danzo had unknowingly handed him a massive gift.
But there was more.
Bai Ye recalled that to unlock the Rinnegan, one required both:
The power of the Mangekyō Sharingan
The Six Paths chakra found in the Senju Clan's DNA
Bai Ye turned his gaze toward the cells of the First Hokage, Senju Hashirama.
Sure enough, the system offered an option to integrate them into his template.
However, unlike his seamless Eternal Mangekyō fusion, this process didn't go smoothly.
The Hashirama cells only provided minor boosts to his vitality and physical strength.
They were insufficient to awaken the Rinnegan.
Bai Ye wasn't surprised.
Even Danzo, who had Uchiha Shisui's Mangekyō and transplanted Senju cells, never unlocked the Rinnegan.
Clearly, ordinary First Hokage cells alone weren't enough.
But that was fine.
Bai Ye knew that during the upcoming Fourth Great Ninja War, Rinnegan and even Rinne Sharingan would appear.
There was no need to rush.
For now, he turned his attention back to his fusion process.
[Detected: The Host currently possesses both the 'Eternal Mangekyō Sharingan' and the 'Mystic Eyes of Death Perception.']
[Would you like to fuse the Eternal Mangekyō Sharingan with the Mystic Eyes of Death Perception?]
[Hint: The stronger entity will consume the weaker one during fusion.]
[There is a small chance of an unknown special mutation.]
[Upon fusion, the Mystic Eyes of Death Perception will inherit the abilities of the Eternal Mangekyō Sharingan.]
"Fusion."
Bai Ye agreed without hesitation.
He had deliberately held off on fusing the One Tomoe Sharingan earlier, waiting until he had an Eternal Mangekyō Sharingan to combine with the Mystic Eyes of Death Perception.
He had originally expected to stop at Mangekyō Sharingan—yet now, he had surpassed that level.
There was no reason to hesitate.
In the depths of the underground base on the outskirts of the Land of Fire, the fusion process began.
When it was complete, Bai Ye lifted Ryūjin Jakka's blade to examine his reflection.
His new eyes glowed with an ethereal azure hue.
Within his purple irises, tiny stars seemed to shimmer.
Encircling his pupils was a secondary ring-like pattern—the unmistakable mark of the Eternal Mangekyō Sharingan.
Bai Ye smirked.
"Danzo... you really were generous with your gifts."
