Kaguya Katsuro was already dead.
But wasting the precious body of a Kaguya clan member didn't seem like a wise choice. Since he had killed him, it was better to pack this body inside his personal sealing scroll.
This relatively intact corpse of a Kaguya clan member—a ninja who had mastered the Shikotsumyaku to a great degree—indeed contained a lot of secrets.
If he remembered correctly, his original grandmother, Otsutsuki Kaguya, had a Kekkei Mora quite similar to the Shikotsumyaku—Dead Bone Pulse.
What was it again?
Yeah!💡
All Killing Ash Bones.
Or so what the ability was named in the anime he saw in his previous life.
The user of that technique strengthened their bones and caused them to protrude from their palms, backs, or other parts of their bodies.
Those dark bone protrusions usually looked harmless.
But the moment they pierced a living organism, whether a person, a beast, or a tree, both the bone and the pierced being's body would start disintegrating into a pile of ash.
There was truly no way to survive if the technique managed to hit someone. It wasn't like other certain-kill techniques that gave people a leeway to survive if they possessed an extraordinary physique, chakra, or endurance.
No.
If All Killing Ash Bones hit you, you would die for sure—no second chances.
This was one of the deadliest techniques wielded by Otsutsuki Kaguya. Whether in the Naruto or the Boruto series, he had never seen any other Otsutsuki use All Killing Ash Bones.
Seimei had long speculated that each Otsutsuki had access to different kinds of unique techniques once they reached a certain level of power.
All Killing Ash Bones was one such unique Jutsu that belonged only to his grandmother, Kaguya.
Cough!
Well, he got sidetracked once again.
The point is…
Shikotsumyaku was a heavily downgraded version of All Killing Ash Bones.
Although Shikotsumyaku had lost All Killing Ash Bone's disintegration power, it retained its ancestral power of hardening and manipulating bones, making it quite deadly to normal ninjas.
As a result, examining the corpse of a Kaguya clan ninja would provide Seimei with significant insights into the abilities of the Otsutsuki clan.
Although he was also an Otsutsuki, for a potioneer and Ninjutsu enthusiast like Seimei, having one source of sample would never be enough.
Only with more specimens that exhibited Otsutsuki characteristics, albeit diluted to the point of being non-existent, could he gain a glimpse into the origin of the Otsutsuki clan and their specialties.
It would help him develop his own Otsutsuki bloodline further, create new Jutsu, and counterattack against the future Otsutsuki invaders.
He wondered if he was becoming more and more like a certain snake uncle.
But he didn't care.
Since Kaguya Katsuro was donating his body to him "voluntarily," Seimei wouldn't shy away from accepting his grace.
All for the advancement of the Ninjutsu. All for the prosperity of Konoha.
Anyway, he wasn't wicked enough to lay his hands on his own people like that slimy snake uncle, so it was fine…probably.
Heh!
Based on seniority, even that slimy snake uncle would have to call Seimei uncle with utter respect. He would keep an eye on the future Orochimaru to make sure he didn't stray into the dark path.
But that aside, having him as an assistant would be nice.
Intelligent people were always welcome.
All those thoughts raced inside Seimei's mind. It might look like he was thinking for quite a while, but he thought of all that within less than two seconds.
And by the time he reined in his random thoughts, he had already opened one of his personal storage scrolls.
And then, without any further ado, he stored the Kaguya clan ninja's corpse and his head inside the scroll.
His hands moved so fast during the corpse retrieval that others didn't even notice him sneakily storing the corpse.
Even if they did, it wouldn't matter.
If his enemies came to stop him, he would have sent them to the Pure Land.
And Konoha ninjas wouldn't even argue against him. That was obvious.
After all, it was the corpse of the enemy he killed, so taking it with him was natural. Secondly, his father was the Second Hokage, Senju Tobirama.
As long as Konoha got to learn about the information stored inside Kaguya Katsuro's brain through the Yamanaka clan's mind techniques, no one would bat an eye.
After retrieving the corpse, Seimei looked around the battlefield.
"Let's see where I need to be."
Seimei looked in Senju Tatsuya's direction. He was still fighting the Shimada clan head. But the Feral Hound was nowhere in sight. He couldn't even detect it using his Tenseigan.
Hmm…the Shimada clan head's summon has either died or been reversed-summoned for some reason.
Then, Seimei shifted his attention to Uchiha Hiroshi, who was fighting the Boneclaw.
"Hmm?"
Seimei looked at the Boneclaw that was trying to distance itself from Uchiha Hiroshi.
But he wasn't surprised.
The Boneclaw's summoner, Kaguya Katsuro, was already dead. In other words, the summoning contract between Katsuro and Boneclaw had been erased.
Naturally, the Boneclaw had no obligation to fight his dead summoner's battles.
In that case, this Boneclaw is probably trying to find the right moment to reverse summon itself. But Uchiha Hiroshi is pressing for attacks, giving it no leeway to escape.
Well, no matter.
Since Katsuro is already dead, the Boneclaw will be reverse-summoned to its original location in a couple of minutes.
Every summoning contract has these clauses to protect the summoning beasts when their summoners die.
Seimei mused for a moment before looking away.
Ding~
Suddenly, he heard a familiar sound of notification in his mind.
[Congratulations! "Flying Thunder God Technique" has leveled up.]
[Flying Thunder God Technique LV4 (3/2,000)]
[You have unlocked "Flying Thunder God Technique—Second Step]
[Flying Thunder God Technique—Second Step: Allows spatial teleportation to a dynamic, non-stationary spatial coordinate through unique Flying Thunder God Marks.]
"Oh!"
Seimei looked at the blue translucent screen in front of him that only he could see.
Seimei's system had one nice feature. If Seimei ever received a notification while he was fighting, practicing, or was in a life-and-death situation, the notification feature of the system wouldn't make a peep until Seimei disengaged and retreated to a safer spot.
It was truly great.
After all, no one would like a bell constantly ringing in their ears when they are engaged in a deadly combat. In such situations, even the slightest distractions could lead to their demise.
I see. I was already pretty close to leveling up the Flying Thunder God Technique to LV4 and unlocking the Second Step.
That was why I felt that I could teleport to Katsuro even when he wasn't standing still in one location.
Good news!
Now, I can teleport to any spatial coordinate, even when the objects or people marked by my Flying Thunder God Seal are moving at high speed.
Those fuckers won't even realize what hit them.
Keke
Hehehehe
Jiejiejiejiejiejie…
Cough cough…ahem…enough nonsense.
Let's focus on killing the remaining Shimada clan bastards and Kirigakure ninjas.
Seimei silently lampooned inwardly.
In the end, he looked around, found a Shimada clan Jonin, and raced toward him.
It's time to destroy this traitorous clan for good.
