The Uzumaki clan has indeed done in-depth research on the soul, because in ancient times, the world was filled with many monsters and demons.
Among them, the mysterious and unpredictable ghosts were very difficult to deal with and were hard to destroy.
Later, it was discovered that these ghosts could be sealed away by sealing jutsu, and then worn out through time.
Sealing jutsu for souls were thus developed.
The Uzumaki clan's research on the soul developed from that period of time. The highest masterpiece is the Dead Demon Consuming Seal, an S-level soul sealing technique that can even take away the Nine-Tailed Fox and seal it in the belly of the God of Death.
As the princess of the Uzumaki clan, and the strongest sealing jutsu ninja today, Uzumaki Mito had certainly inherited the legacy of the Uzumaki clan, and had a deep understanding of the souls and even the Pure Land.
As such, she understood very well that the soul of a first-time out-of-body experience was extremely fragile.
Not to mention moving, it was estimated that even a gust of wind could show signs of festering.
And how special is the soul of Kirito in front of her. She didn't expect that his soul is so powerful and solid. He can move as soon as he leaves his body. If she hadn't seen it with her own eyes, she might not believe that everything in front of her is real.
After Kirito moved around the room for a short while, he felt a bit tired and had a tingling sensation.
He realized that something wasn't right, and then smoothly reentered back into his physical body under the surprised gazes of Mito and Kushina.
After ten seconds or so, Kirito reopened his eyes and immediately realized that he had a feeling that his body had been hollowed out and that he was so mentally exhausted that he couldn't wait to lay down on the floor and get a good night's sleep.
He wanted to stand up and move his body, but he almost fell down. Fortunately, Kushina next to him was quick to pull him up, so he didn't fall to the ground.
"Thanks, Kushina."
Kirito thanked.
When Kushina heard this, her smiling face slightly reddened, and she hurriedly loosened her grip on Kirito's shoulders.
And as soon as she let go, Kirito fell smoothly on top of her kneeling legs.
"Ah!!!"
Kushina instantly screamed and pushed Kirito away with all her might.
Although Kushina looked small and still skinny, her strength was not trivial, and Kirito's entire body flew straight out, hitting his head hard against the wall and plunging it in.
"You, are you alright?"
Kushina just pushed Kirito away, then realized that he had done something wrong, and said with some fear.
Kirito was physically okay, he struggled to get his head out of the wall, his forehead left blood looking at Kushina, smiled and said, " it's fine."
As soon as the words left his mouth, he rolled his eyes and fainted, collapsing on the ground and huffing and puffing.
Kushina thought that Kirito had died, and was so scared that her face was bloodless and trembling, looking at Mito pitifully.
Mito saw this, couldn't help but laugh badly, and only after seeing Kushina anxious to cry, she consoled: "Don't worry, this kid is sturdy, he won't die, but when he wakes up, remember to apologize, ah, you now go and take him to the guest room inside to rest."
Kushina immediately nodded her head obediently before carrying Kirito and quickly leaving the room.
Once Kushina left, Mito quickly tightened his smile and spoke, "Momo."
"Lord Mito, please command."
Momo Senju instantly appeared in front of Mito on one knee and respectfully said.
"Go tell that old brat Sandaime to bring the Spirit Transformation Jutsu, and also, tell him and that brat Danzo to keep an eye on him, if the slightest thing happens to Kirito, I'll make both of them look bad."
Mito said with a cold face.
"Ha."
Momo led the way and made an body-flicker jutsu and disappeared into the room.
"That idiot Tobirama, how did he leave the village in the hands of that idiot Hiruzen, And that kid Danzo is getting more and more outrageous in order to achieve his goal. He has even learned the Will of Fire from a dog. We shouldn't have let such a guy be an advisor..."
After Momo left, Mito's face showed a pout, both chagrined and worried.
Sandaime and Danzo were going to use Kirito to fish out spies hidden in the village, something she had of course already learned from Momo.
When she had learned of it, she had been so furious on the spot that she had almost caused a serious leak of the Nine Tail Chakra.
If it had been two years ago, and Sandaime and Danzo had dared to do this, she would have immediately stepped in to teach these two fools a lesson.
Unfortunately, her days are numbered now, suppressing the Nine Tails in her body is a bit of a struggle, if she forced her hand, she probably can't wait for the day when Tsunade returns from the battlefield.
She had no choice but to utter a warning.
"Hashirama, I don't understand the village you left behind any more. I hope that the new buds of Konoha will continue to thrive and then everything will be back on track..."
Mito closed her eyes, a deep exhaustion showing on her face, and sighed.
...
At night, in the Uchiha clan land, in the training ground in the backyard of Chizuru's house.
At this time, Chizuru was conducting her daily necessary practical combat class, her opponents today were three elite Chunin from the Uchiha clan.
At this time, Chizuru's outfit was no different from that of the daytime, the only difference was that there was an extra slender longsword in her hand.
Under the light, the long sword was frigid, giving off an indestructible sharpness.
This sword was called Lightning Strike, a famous sword made of chakra metal mixed with a special lightning-attributed metal, not only did it possess excellent chakra conductivity, but also, as its name suggests, once injected with chakra, it would automatically give birth to lightning.
As Uchiha Homura watched, the battle began.
Chizuru opened her eyes, her Sharingan was activated, and lightning chakra instantly covered her limbs.
Drawing her sword, a sizzling sharp thunder suddenly appeared.
In the next moment, more than a dozen Chizuru with different forms suddenly appeared on the training ground where the thunder light appeared.
When the thunder light was silent, the three elite chuunin let out a miserable scream almost simultaneously, taking swords in their chests, spraying hot blood, and falling to their knees with stunned faces.
"Ka-da~"
Chizuru appeared behind the three and sheathed his sword.
Between the swiftness and lightning, he lightly took down the three elite Chunin.
At this point, if it was a life and death duel, the three elite chunin had already been decapitated by her.
"Not bad, Lightning Stimulation Secret Art you have completely mastered, but try not to use the trick just now in the future. It's best to use it as a trump card to decide the victory. That move just now can be famous ah?"
Uchiha Homura watched Chizuru instantly defeat three elite chunin of the same clan in seconds, nodded his head in delight and praised.
Defeating three elite chunin at the same time was actually not a difficult task, every Konoha jonin who had gone through a rigorous assessment could do it.
Even the elite chunin of the Uchiha clan was the same.
However, for a girl as young as eight years old to be able to do this, it could only be described as terrifying.
Now, the granddaughter he had high hopes for did this.
"Lightning Flash."
Chizuru spat out two words expressionlessly.
After saying that, she turned around and walked towards the house, without looking at the three elite Chunin on the ground again.
