After parting ways with the others, Shihōin Naraku headed straight to the laboratory alone and soon found the busy Second Hokage Tobirama Senju.
"Any results?"
Naraku's voice rang out in the quiet laboratory, rousing Tobirama Senju from his thoughts.
"Yes. After spending a few days studying the Impure World Reincarnation Jutsu improved by Orochimaru and Kabuto Yakushi, I did find a solution."
Tobirama Senju picked up two sheets of paper from a nearby Experiment Table and handed them over.
Naraku took a look and found that both sheets were covered in jutsu formulas, with a large character for "seal" right in the center!
"These are..."
"Sealing talismans!"
"Sealing talismans?"
Naraku raised an eyebrow slightly and examined the two sealing talismans in his hands.
Even without an explanation from Tobirama Senju, he could guess what these two talismans were for.
As their name suggested, they were surely meant to seal the dead summoned through the Impure World Reincarnation Jutsu!
"Orochimaru and Kabuto Yakushi improved the Impure World Reincarnation Jutsu, greatly increasing the strength of the dead summoned through Summoning and allowing them to fight without many restrictions."
Tobirama Senju began explaining to Naraku. "In that respect, those two truly are rare geniuses."
At this point, Naraku could clearly hear the regret in Tobirama Senju's voice.
He evidently felt it was rather a shame that such geniuses were wandering outside the village and had ultimately become the foremost enemies of the Shinobi World.
But he only dwelled on it briefly before continuing, "The improved Impure World Reincarnation Jutsu has many advantages, but it also has some flaws and problems."
"For instance, the compatibility between the dead person's soul and the vessel!"
Naraku frowned at that. Had it been some other problem, he would not have been so sure.
But as for problems
