After Kirito finished his bath and changed his clothes and came out of the guest room, he saw a dozen or so Kawaki in the living room looking at a sealing jutsu with his head covered in thought, unable to do anything about it.
Although Kawaki didn't like sealing jutsu, his sealing jutsu practice wasn't over for a day.
It had to be said that diligence made up for clumsiness.
After two years of practicing, Kawaki had separated more than ten shadow clone to study together every day, the sealing jutsu had progressed, and he was barely able to make the Sealing Jutsu - One Series Light Formation, and he had a detailed knowledge of many sealing jutsu.
"Kirito, you're just in time, come help me quickly, this stupid question is driving me crazy."
"You can finally come out, how should I solve this stupid problem, the formula you taught me last time doesn't match up."
"Ah ah ah ah, can't take it anymore ah ..."
...
More than a dozen Kawaki saw Kirito appeared, and all of a sudden brushed their eyes to Kirito, yelling for help.
Kirito turned a blind eye to this, dodging the sneak attacks of multiple Kawaki with his dexterity, and quickly coming into the courtyard.
Seeing Kirito enter the courtyard, Kawaki didn't dare to continue chasing after him, absentmindedly retreating back and continuing to look at the sealing jutsu on the paper with a sad face.
After crossing a section of the courtyard, Kirito came to the house where Mito usually rested.
By this time, the door to the house was already open, and Kirito could see from afar that Mito was teaching Kushina the sealing jutsu.
Compared to two years ago, Mito was no longer young and beautiful, and had returned to what she should look like at her current age, a kindly old woman with long, beautiful red hair, most of which had now turned silver.
The Yin Seal imprint on her brow was still there though.
Under Kirito's perception, Mito's chakra had not only not weakened, but had instead become more powerful, only that the chakra that was originally filled with a sunny feeling now had an additional cold and evil feeling.
Without a doubt, that was a sign that the Nine Tails chakra was beginning to show signs of leakage.
"Mito-sensei, I'm here."
Kirito came to the door of the room and greeted Mito with a regular smile.
"Here you are, have a seat and look at this."
Mito said as he smiled at Kirito before handing him a scroll.
Kirito walked into the room and took the scroll handed to him by Mito with both hands before scowling at Kushina, who was peeking over, before slowly opening it up.
As soon as he saw the contents on top of the scroll, his expression instantly froze.
Recorded on the scroll was a sealing jutsu that he had never learned before, it was called Dead Demon Consuming Seal.
It was a very powerful sealing jutsu with a rank of S. Moreover, it was a rare attack-type sealing jutsu, where he summoned the Grim Reaper and then sealed the enemy's soul into the Grim Reaper's body at the cost of his own soul, achieving the effect of dying with the enemy.
With Kirito's current sealing jutsu attainments, he naturally understands how to perform this sealing jutsu, and given a little time, learning it is not a problem.
However, even if he learns it, he can't perform it for the time being because he doesn't have enough chakra.
The conditions for releasing this sealing jutsu didn't only require the sacrifice of one's soul, but also chakra of at least the upper shinobi level.
"Well, can you read it?"
Mito noticed the expression on Kirito's face and inquired.
"I can see it, I guess it will take a week to learn it."
Kirito answered honestly.
"Since you can read it, I'll give you an assignment to develop a jutsu for summoning souls based on this sealing jutsu, let's cut it off until dinner."
Mito nodded in satisfaction, then immediately laid down a long overdue homework for Kirito.
"Yes."
When Kirito heard Mito's words, he immediately realized Mito's intention and said excitedly.
This Dead Demon Consuming Seal came with its own jutsu on how to sacrifice souls, all he needed to do was to take them out and add some generalized jutsu to them, and he would soon be able to create a simple ninjutsu that summoned out souls, which wasn't too much of a challenge for him.
As for why Mito made him do that, it was obvious that Mito already knew the conditions for him and the Sandaime to learn the spirit transformation technique, and Mito did have a method to detect the qualifications of souls.
About this, Kirito had no doubt.
After all, the Uzumaki clan had even developed an S-rank soul sealing jutsu like Dead Demon Consuming Seal, so to say that they hadn't conducted in-depth research on souls would be impossible.
All he needed now was to complete this Ninjutsu of summoning the soul, and then he would be able to have Mito test his soul qualifications on his own.
Without delay, he immediately took out a storage scroll and used the Summoning Jutsu - Release Technique to take out a blank scroll and pen and ink from inside, then began to quickly write down some jutsu on a piece of paper.
Kushina couldn't help but secretly watch and found that Kirito didn't need to look at the formula on the scroll to write the formula on the paper. She immediately complained: "Look at how capable you are. You only looked at the sealing technique on the scroll once. I don't believe that you can successfully create a new ninjutsu without looking at the formula on it again."
Sealing jutsu a very strict jutsu, as long as a jutsu is written incorrectly, it is impossible to successfully activate it.
"Pah~"
A scroll knocked hard on Kushina's head.
Kushina instantly covered her head and hurriedly withdrew her gaze from Kirito, then continued to concentrate on listening to Mito's explanation of the sealing jutsu.
Kirito's presence was too high, Kirito was the only male in the room, and a sealing jutsu genius with much better talent than herself, Kushina still couldn't help but sneak a peek at Kirito to see if he was successful.
As a result, only ten or so minutes had passed when she heard Kirito say, "It's done, Mito-sensei, please take a look."
Kushina immediately looked over to Kirito's side, just in time to see Kirito use his hand to follow the top of the center of a jutsu formation formed by many jutsu on a piece of paper, and with the injection of chakra, the entire jutsu formation suddenly lit up.
The next moment, she saw a pure white Kirito float out from within him.
"This worked?"
Kushina looked at that pure white Kirito and was inwardly shocked.
She wasn't wrong, that pure white Kirito was none other than Kirito's soul without a doubt ah.
"Is this the feeling of an out-of-body soul, vision is normal, perception has become sharper than usual, it just feels a bit cold."
Kirito looked at the lower hair's motionless flesh lying on the ground, then looked at his current appearance, closed his eyes, and carefully experienced the changes that occurred in his soul state in the moment.
Meanwhile, Mito carefully surveyed Kirito's soul.
Soon, a look of surprise appeared in her eyes as she saw that Kirito in his soul state was actually walking around the room without a single sign of his soul collapsing, it was still solid.
"What amazing soul power, this disciple of mine is really a monster."
