"Shuttle through space-time, return to the past!?"
Karin was full of astonishment; she never expected such a treasured tool to exist in the shinobi world!
If not for Urashiki's attack, Shinji actually wouldn't have thought of this matter either. He also thought of 'Karasuki' while considering how to ambush Urashiki.
Karin then asked: "Do you know where 'Karasuki' is?"
Shinji shook his head: "I'm not too clear where 'Karasuki' is now; it should be in some lost ruins!"
In the original timeline, 'Karasuki' was accidentally discovered by the Land of Fire's archaeological team while exploring certain ruins, then sent to the Hidden Leaf Village, and then intercepted by Urashiki.
So even knowing 'Karasuki' was lost in the shinobi world, Shinji currently couldn't be sure if Urashiki sensed 'Karasuki's existence and then stole 'Karasuki' from the Hidden Leaf Village, or if Urashiki simply learned that the Land of Fire's archaeological team discovered 'Karasuki' and then infiltrated the Hidden Leaf to steal 'Karasuki'.
Karin frowned slightly: "Then what should we do?"
After thinking for a moment, Shinji said: "Notify the Hidden Leaf to organize several archaeological teams to conduct archaeological exploration throughout the Land of Fire."
"En!"
Karin nodded.
Shinji said: "If we can find 'Karasuki', we will publicize it widely to see if we can attract Urashiki!"
Because 'Karasuki' wasn't in hand, using this treasured tool as bait to lure Urashiki could only be considered a backup plan.
Shinji had already made up his mind. If neither the giant Tenseigan nor 'Karasuki' could lure out Urashiki, he would think of a way to nurture a third 'Chakra Fruit', using the 'Chakra Fruit' as bait to lure Urashiki out.
He didn't believe the Otsutsuki could resist the temptation of a 'Chakra Fruit'!
After sending Karin to handle the matter of 'Karasuki', Shinji came alone to the central training ground inside the fortress.
Sitting cross-legged, Shinji took out the three small nutrient jars containing Momoshiki's and Kinshiki's two pairs of Byakugan and one pair of Red Rinnegan, placing them in front of himself.
Gazing back and forth at the three nutrient jars, Shinji pondered.
Using 'Susanoo Tomoshibi' to fuse eyes carried certain risks. With Shinji's current pupil power, fusion failure shouldn't happen, but fusing a new eye that wasn't what he wanted was a situation that could possibly occur.
"Even if something goes wrong, at least I should be able to recover a pair of Red Rinnegan, the problem shouldn't be big..."
Having weighed the pros and cons, Shinji hesitated no more, instantly activating 'Susanoo' and 'Susanoo Tomoshibi'.
As a golden phantom projected from his body, in the blink of an eye, a majestic, half-body armored deity appeared in the central training ground.
Currently, his 'Susanoo's head had three faces in total, front, left, and right, with six pairs of eye sockets. Besides his own eyes, 'Susanoo Tomoshibi' could additionally subjugate five pairs of eyes.
Because Shinji's own dojutsu leaned towards the time side and was somewhat lacking on the space side, he usually chose to subjugate Obito's and Madara Uchiha's two pairs of 'Six Tomoe Rinnegan', as these two pairs contained two powerful Space-Time Dojutsu, 'Kamui' and 'Limbo: Border Jail', respectively.
As for Obito's Rinnegan dojutsu, perhaps due to the existence of 'Kamui', he didn't awaken a Space-Time Dojutsu like everyone else, but the will sword 'Sword of Nunoboko' that Obito had used in the great battle with Shinji before.
The power of this dojutsu was strongly correlated with one's own will. The stronger the willpower, the greater the power of the dojutsu, which fit Obito's character quite well.
Besides the two pairs of 'Six Tomoe Rinnegan', Shinji usually also subjugated the 'Tenseigan' awakened by Neji and Kimimaro, as well as the 'Kokugan' seized from Isshiki.
The last pair of empty eye sockets was basically left empty, sometimes subjugating Shisui's pair of Mangekyo Sharingan depending on the situation, and sometimes subjugating Hiruko's pair of Mangekyo Sharingan.
Now Shinji needed to fuse three pairs of eyes at once, so he removed all the eyes previously subjugated by 'Susanoo Tomoshibi', then subjugated Momoshiki's and Kinshiki's two pairs of Byakugan and one pair of Red Rinnegan one by one.
"Eh..."
Shinji let out a light sound of surprise.
Although he subjugated two pairs of Byakugan and one pair of Red Rinnegan, which seemed lower in quality than the 'Six Tomoe Rinnegan', the pupil power amplification they provided him was absurdly strong.
The pupil power amplification provided by Momoshiki's pair of Byakugan was almost equivalent to the Tenseigan. Kinshiki's Byakugan was slightly inferior, but the pupil power increase wasn't small either.
As for Momoshiki's pair of Red Rinnegan, the pupil power amplification provided was far higher than Obito's and Madara Uchiha's 'Six Tomoe Rinnegan'.
"It seems it's still due to chakra characteristics. The dojutsu Bloodline Limits in the shinobi world almost all originate from Kaguya Otsutsuki, with similar characteristics. While Momoshiki and Kinshiki are from another branch of Otsutsuki. Subjugating their eyes is just like subjugating Isshiki's 'Kokugan', equivalent to completing certain chakra characteristics, so the pupil power amplification is this significant."
Thinking of this, Shinji looked forward even more to fusing that pair of 'Golden Rinnegan' Momoshiki obtained after swallowing Kinshiki and transforming in the original timeline.
Restraining his divergent thoughts, Shinji then used 'Susanoo Tomoshibi' to sense the dojutsu contained in the Red Rinnegan.
Unsurprisingly, the dojutsu in this Red Rinnegan was 'Takamimusubi', with the ability to absorb and strengthen enemy jutsu.
Of course, this was the usage at the 'Six Paths Level'.
In the eyes of Shinji who had already become a 'Kekkei Mora', the use of this jutsu was definitely not just a strengthened version of 'Blocking Technique Absorption Seal'. The principle of strengthening absorbed ninjutsu was actually an improvement in chakra quality.
And for Shinji, this was a very important ability because he speculated that the so-called 'Shinjutsu' were jutsu driven by extreme chakra. This was also why Eida, Daemon, and Orochimaru, who obtained Shibai Otsutsuki's power, could possess 'Six Paths Level' combat power despite being unable to even condense 'Truth-Seeking Balls'.
The level of chakra is the key. Others like technique, experience, mentality, willpower, etc., can all be compensated through training, but the level of chakra is very difficult to improve through training.
Therefore, any dojutsu capable of improving chakra quality and prompting the improvement of chakra level was an SS-rank dojutsu in Shinji's eyes.
As for Momoshiki's and Kinshiki's two pairs of Byakugan, they contained two kinds of chakra control dojutsu, 'Cinnabar Panacea' and 'Ama-no-Habaya', respectively.
'Cinnabar Panacea' could absorb enemy ninjutsu or chakra creations and refine them into chakra pills to replenish one's own chakra consumption. While 'Ama-no-Habaya' could use chakra to create various chakra weapons.
The strength of these chakra weapons is related to the caster's chakra quality. If Shinji used 'Ama-no-Habaya' to create chakra weapons, the strength should not be inferior to divine artifacts like the Kusanagi Sword...
