"As expected, it worked!"
Looking at the newly born 'Kokugan' in his palm, the corners of Shinji's mouth curled up slightly.
Just now, he used 'Yachihoko' to extract Isshiki Otsutsuki's own chakra, and infused this chakra into Isshiki Otsutsuki's Byakugan through chakra impact, successfully evolving this Byakugan of Isshiki Otsutsuki into a 'Kokugan'.
This also verified his previous speculation that the innate Byakugan of the Otsutsuki clan possessed the possibility of evolving into any dojutsu Kekkei Genkai!
Of course.
The reason Shinji could evolve the Byakugan into 'Kokugan' so easily was mainly because this Byakugan itself was a pure Byakugan belonging to Isshiki Otsutsuki.
If he just found a random Byakugan, even if he used 'Yachihoko' to launch a chakra impact on it, he couldn't catalyze it into a 'Kokugan'.
Obtaining another 'Kokugan', Shinji examined it carefully, then couldn't wait to activate 'Susanoo'.
After activating 'Susanoo Tomoshibi' and controlling a pair of 'Kokugan', Shinji felt it seriously.
First was naturally the amplification of pupil power. As he expected, after gathering a pair of 'Kokugan', the amplification effect of pupil power nearly doubled. The pupil power improvement he obtained by controlling a pair of 'Kokugan' now was almost fifteen times that of controlling a pair of Rinnegan.
Therefore, after completing the control, he felt a slight swelling sensation in his eyes.
Swelling, stinging pain, these were not unfamiliar to dojutsu Kekkei Genkai. These feelings were normal situations after pupil power increased significantly or was consumed significantly in a short period.
Just that Shinji didn't expect that even having sealed the Ten-Tails and advanced to 'Six Paths Level', he would still experience this strange feeling. Just this point alone showed how exaggerated the pupil power improvement Shinji obtained after controlling this pair of 'Kokugan' with 'Susanoo Tomoshibi' was!
"Dojutsu didn't change much..."
Shinji felt the pupil techniques contained in this pair of 'Kokugan' again, finding they were still 'Daikokuten' and 'Sukunahikona'.
This point was actually within his expectations.
Because if stronger pupil techniques were awakened by gathering a pair of 'Kokugan', Isshiki Otsutsuki wouldn't have maintained the configuration of one Kokugan and one Byakugan.
However, the pupil power of two eyes was obviously stronger than one. So after gathering a pair, Shinji found the effects of 'Daikokuten' and 'Sukunahikona' were stronger, and the consumption was smaller.
Resting his chin on his hand, Shinji counted all the eyes he had collected so far.
His own pair of 'Six Tomoe Rinnegan', and the scarlet 'Nine-Tomoe Rinnegan' between his eyebrows were not mentioned.
Now counting the eyes of his subordinates, the high-level dojutsu Kekkei Genkai Shinji possessed included a pair of 'Kokugan', originally belonging to Isshiki Otsutsuki. Three pairs of 'Six Tomoe Rinnegan', belonging to Karin, Hikari Uchiha, and Sasuke Uchiha respectively. Two pairs of 'Tenseigan', belonging to Toneri Otsutsuki, Neji, and Kimimaro respectively.
A pair of 'Rinnegan', originally belonging to Madara Uchiha.
A pair of 'Ketsuryūgan', belonging to Yakumo.
Two and a half pairs of 'Mangekyo Sharingan', one pair from Shisui Uchiha, one pair from Hiruko, and one from Obito.
A pair of 'Super Ketsuryūgan', belonging to Ranmaru.
Further down, scattered Sharingan, Ketsuryūgan, Ketsuryūgan, ordinary Byakugan, these had little significance for the current Shinji. Because Shinji could create such low-level dojutsu Kekkei Genkai relying on his ability to edit chakra.
Calculating this way, Shinji mastered quite a lot of high-level eyes.
And his 'Susanoo Tomoshibi' had a total of six pairs of eye sockets, five pairs of empty eye sockets. So how to control, which eyes to control, whether focusing on pupil power or pupil techniques, etc., were all issues needing careful consideration.
"'Kokugan' must be controlled. Whether pupil power amplification or pupil techniques, the cost-performance ratio is too high..."
"Later must control a pair of 'Tenseigan'. Without a killing move like 'Golden Wheel Reincarnation Explosion', it's hard to deal a decisive blow to powerhouses of the same level."
'Kokugan' and 'Tenseigan' occupying two pairs of empty eye sockets was basically undisputed.
'Kokugan' aside, 'Tenseigan' belonged to Hamura Otsutsuki's lineage, while the Uchiha clan Shinji belonged to was Hagoromo Otsutsuki's lineage. Although both were Kaguya Otsutsuki's bloodline, there was still a significant difference in chakra attributes. So the pupil power amplification Shinji obtained by controlling 'Tenseigan' far exceeded that of controlling 'Rinnegan'.
Thus, Shinji only had three pairs of empty eye sockets left.
The remaining eyes worth controlling were 'Six Tomoe Rinnegan', 'Rinnegan', 'Mangekyo Sharingan', 'Ketsuryūgan', and Ranmaru's 'Super Hogan'.
In terms of the strength of pupil power amplification effect, 'Six Tomoe Rinnegan' was undoubtedly the strongest.
But right now, except for Shinji's own, the other three pairs of 'Six Tomoe Rinnegan' all had owners. If just for a small amount of pupil power enhancement, taking away Karin, Hikari, or Sasuke's eyes would undoubtedly be a loss-making deal.
After all, the three of them all had the potential to formally step into 'Six Paths Level'!
Moreover, Shinji still had Madara Uchiha's pair of 'Rinnegan' in hand. With a little effort, this pair of 'Rinnegan' could also evolve into 'Six Tomoe Rinnegan'. So even if wanting to control a pair of 'Six Tomoe Rinnegan', it was better to choose this pair.
Tap tap tap...
Tapping the ground lightly with his fingers, Shinji continued to analyze which two pairs of eyes to control for the remaining two pairs of empty eye sockets.
Obito's Mangekyo Sharingan containing 'Kamui', although controlling it had almost no amplification in pupil power, the pupil technique 'Kamui' itself was extremely valuable.
Especially after the space-time pupil technique awakened by Shinji's 'Six Tomoe Rinnegan' was 'Goshingū' purely in the time domain, the flexible and versatile 'Kamui' was even more attractive to him.
So although it was just a Mangekyo Sharingan, and only one, Shinji didn't want to give up Obito's Mangekyo Sharingan containing 'Kamui'.
"A pair of 'Kokugan', a pair of 'Tenseigan', a pair of 'Six Tomoe Rinnegan', a pair of 'Mangekyo Sharingan'..."
Shinji muttered while temporarily confirming the four pairs of eyes needing to be controlled.
In this way, together with his own eyes, a total of five pairs of eye sockets were used, leaving only the last pair of empty eye sockets.
"Which pair of eyes to control for the remaining quota? Is it Hiruko's pair of Mangekyo Sharingan capable of manipulating emotions? Or Yakumo's 'Ketsuryūgan' capable of manipulating blood? Or Ranmaru's 'Super Hogan' capable of creating phantoms?"
