Tamura Hiroshi was secretly brought to a research department located inside a mountain belly on the fourth day, still wearing a mask on his face to avoid exposing his identity.
"Is that the Eight-Tails' tentacle?"
Looking at the huge tentacle sealed inside from the glass window, Tamura Hiroshi could not understand the morphology of the Eight-Tails at all.
The lower body of this kind of octopus tentacle could hardly provide it with strong support, and the structure was far too unreasonable.
"The Third Raikage was able to suppress the Eight-Tails, cutting off its tentacles multiple times during the combat process, and those tentacles were all sealed away by us.
There were once two geniuses produced by our village, who were the most heinous criminals Kinkaku and Ginkaku. They ingested the flesh and blood of the Nine-Tails and thus gained the power of the Nine-Tails, and we wanted to replicate this by borrowing from that, but unfortunately we have never succeeded."
Dodai at the side sighed. Kinkaku and Ginkaku were too strong back then. If Lord Dodai had not mastered the Hell Stab, he feared it would have been difficult to even break the Tailed Beast Cloak on them.
"Lord Dodai said that the utilization of the tailed beasts is modeled after the First Hokage's wife, sealing the tailed beasts into the bodies of powerful shinobi using sealing techniques, only that the sealing technique grade of our village is not high enough to seal a tailed beast.
A complete tailed beast is too strong, and indeed not easy to seal, but if it is just a part, it shouldn't be difficult, right? This is definitely safer than directly ingesting the flesh and blood of a tailed beast."
Looking at the huge octopus tentacle, Tamura Hiroshi put forward his thoughts in this regard.
This was actually not his own idea either. In the future Fourth Shinobi World War, Kabuto Yakushi had once sealed the Eight-Tails Horn cultivated by Orochimaru into Fukai's body, and it also erupted with the power of the tailed beast.
And then there was that False Nine-Tails Jinchuriki of the Temple of Fire. Relying purely on collected Nine-Tails Chakra allowed him to become a jinchuriki, proving that this line of thought was feasible.
"Slap!"
"Why didn't we think of that?"
After being stunned for a moment, Dodai slapped himself directly in the face, and then became excited.
Right, a complete tailed beast was not easy to seal nor easy to carry, but simple tailed beast flesh and blood certainly wouldn't be that difficult.
"This token can let you move through the research institute without obstruction."
Taking out a token and handing it to Tamura Hiroshi, Dodai ran off eagerly, preparing to go find the Third Raikage to report this matter.
If this line of thought could succeed, their Kumogakure would make a fortune.
"Give me a piece of the Eight-Tails' flesh."
Tamura Hiroshi said this to the ANBU ninja guarding the door of the room where the Eight-Tails tentacle was sealed, feeling very interested in the tailed beast's flesh.
This ANBU ninja had previously seen Dodai's attitude toward this person, so he didn't say much more, opened the room door, and took out one piece from the pre-cut tentacle flesh specimens, handing it to Tamura Hiroshi.
"Is this the chakra of the tailed beast?"
Looking at the crimson chakra emanating from the flesh inside the bottle filled with sealing technique formulas, Tamura Hiroshi understood that was the chakra of the Eight-Tails.
"Where is the storage location for the Sharingan?"
Sealing that sealed bottle into the storage scroll he had brought, Tamura Hiroshi asked the ANBU ninja for the storage location of the Sharingan.
"Follow me!"
The ANBU ninja performed hand seals to shape a clone, signaling Tamura Hiroshi to follow, and led him toward the laboratory where the Sharingan was studied.
The researchers in charge of that section saw that it was someone brought by the ANBU and that he also held the Raikage's Assistant's Order in his hand, so they didn't say much.
"Are there any scrapped Sharingan available for research?"
Flipping through the research reports related to the Sharingan in the laboratory, Tamura Hiroshi brought up wanting scrapped Sharingan.
He knew the key to the Sharingan lay in dojutsu power; the eye structure was only secondary.
Furthermore, Kumogakure had already figured out the research on eye structures, and the gains were not large.
"There are!"
Seeing that Tamura Hiroshi only asked for scrapped Sharingan, the person in charge breathed a sigh of relief and took out several bottles from the refrigeration cabinet at the side, inside of which soaked four dissected Sharingan.
"Give me a quiet room."
Taking those bottles, Tamura Hiroshi stated his request, wanting to make some attempts.
The person in charge didn't say anything more and led Tamura Hiroshi to a lounge nearby.
"I hope it succeeds!"
Whispering softly, Tamura Hiroshi took out a Sharingan and held it in his hand, refined chakra to wrap around it, and cast the Chakra Absorption Technique.
The Chakra Absorption Technique was actually not rare; many jutsu possessed the property of absorbing an opponent's chakra, especially Earth Release and Water Release.
For instance, Jirobo's Earth Style: Earth Prison Dome of Nothingness among the future Sound Five, while Kisame Hoshigaki could absorb an opponent's chakra directly.
Of course, Tamura Hiroshi's grade of this Chakra Absorption Technique was not high; he had gotten it from Dodai previously.
Moreover, the focus was on absorption, while the refinement capability was very poor, and he himself lacked Water Release and Earth Release to augment it, making the effect even worse.
Under the effect of the Chakra Absorption Technique, the Sharingan, which had already been damaged by research, could not withstand it and shattered. The dojutsu power within was wrapped and absorbed by Tamura Hiroshi's chakra, and soon the pale blue chakra gained a share of crimson.
However, this was merely a simple mixture rather than fusion and refinement, because the dojutsu power grade of the Sharingan was far too high, vastly exceeding Tamura Hiroshi's chakra.
This was the flaw of the Chakra Absorption Technique—it was unable to absorb chakra of a higher quality than one's own.
Still, this was enough; Tamura Hiroshi never thought of relying on his own strength to refine the Sharingan's dojutsu power—that was unrealistic.
In this aspect, he had to rely on his Golden Finger!
Taking a deep breath, he decisively pressed that mass of crimson chakra onto his forehead, guiding and leading it inward with his own internal chakra into the spiritual world where the Golden Finger resided.
Sure enough, the Sharingan's dojutsu power was scanned by the Golden Finger at the very first moment, instinctively treated as a foreign invader to be suppressed and decomposed.
Soon four phantom imprints were separated out, still the same four from last time, and the imprint phantom separated out last was also the most hazy and illusory.
Tamura Hiroshi looked at those four phantoms, then immediately used the power of the fragmented jade piece to grind down the Sage of Six Paths, Ōtsutsuki Isshiki, and the fourth phantom, and then pushed the pulverized imprint origin in front of the Ōtsutsuki Kaguya phantom.
Just as he had guessed, the Ōtsutsuki Kaguya phantom instinctively began to devour them, especially the imprint fragments of Ōtsutsuki Isshiki and the Sage of Six Paths which were devoured the fastest, followed only then by that final imprint.
That imprint was hidden the deepest and possessed the highest grade; the Kaguya phantom devoured and refined it with great difficulty, but fortunately it had already been pulverized by the power of the fragmented jade piece, becoming the most basic nourishment without the power to resist.
Along with the devouring of the three imprints, the Kaguya phantom solidified just a little bit, and then Tamura Hiroshi pushed the Sharingan's dojutsu power over, which it also instinctively went to devour, and subsequently a dot of blood-red light appeared between its brows.
"The guess is correct. We can rely on chakra to awaken and enhance Ōtsutsuki Kaguya's will and power, especially the chakra wills obtained from the bloodline descendants left behind by the Sage of Six Paths, which are the most powerful."
Looking at that dot of blood-red light between the brows of the Kaguya phantom, Tamura Hiroshi confirmed a previous conjecture.
This was a conjecture he made based on the resurrection of Ōtsutsuki Kaguya and the corpse-bounding appearance of the Sage of Six Paths in the Fourth World War. Both of them left their own wills within their chakra, which was why Princess Kaguya would say she was taking back her own chakra rather than seizing and harvesting it.
This proved that it was originally someone else's chakra to begin with, and it wasn't simply a matter of just a source.
Therefore, anyone in the ninja world facing Princess Kaguya would find it difficult to have any power to resist, facing even greater pressure than when dealing with Ōtsutsuki Isshiki and the others. That was a suppression originating from deep within the bloodline and the essence of chakra, unless one could reach the Six Paths level.
And this point was precisely what he had taken a fancy to, which was why he chose the imprint phantom of Ōtsutsuki Kaguya.
Of course, the most important thing was that Ōtsutsuki Kaguya was the only female among the four, and she seemed a bit naive, so even if this Kaguya phantom gained intelligence in the future, it would be much easier to trick.
