"Impure World Reincarnation Jutsu! ×2"
Soji and Shikaku Nara shouted the name of a forbidden technique in unison.
The next second, the two quickly exchanged glances.
However, Shikaku Nara's expression was visibly even uglier than Soji's.
Still, Shikaku Nara swiftly composed himself.
"Commander-in-Chief, you recognize this forbidden technique of Konoha as well?"
Shikaku Nara was still somewhat puzzled.
After all, not long after the Impure World Reincarnation Jutsu had been developed, the First Hokage, Hashirama Senju, had ordered his younger brother, Tobirama Senju, not to continue refining it.
Hashirama Senju's attitude toward his brother had been simple: Tobirama could develop Water Release ninjutsu however he wanted, but forbidden techniques like Impure World Reincarnation were not to be researched further.
That was also why the original version of the Impure World Reincarnation Jutsu could only be used together with Explosive Tags.
Tobirama Senju's technique had been sealed away not long after he first developed it.
After all, the original version of the Impure World Reincarnation Jutsu probably could not even allow the dead to display ten or twenty percent of their strength from when they were alive.
That was why Shikaku Nara was so curious about why Mizuki Ember was so familiar with this ninjutsu.
After all, prying into the forbidden techniques of other shinobi villages was taboo!
By all rights, even within Konoha, there might not have been many ninja who knew of this forbidden technique.
Upon hearing Shikaku Nara's question, Soji was momentarily stunned. Then he quickly reacted and thought of how to answer it.
"Mr. Shikaku, have you forgotten? When Konoha, Kirigakure, and Sunagakure held the Joint Chunin Exams, the First Hokage and Second Hokage of Konoha, as well as the Third Kazekage of Sunagakure, all appeared in your village's Forest of Death, didn't they?"
Soji explained calmly.
