Kotoamatsukami

After the meeting, Yichen took Sokai to the Medical Department first.

Yichen directly had Nakata Hajime transplant Shisui Uchiha's eye into Sokai's left eye.

After the surgery, Yichen asked Sokai, "How was it? Did you have any rejection reactions?"

Sokai assess the situation, he said, "It's alright, there's a slight rejection reaction, but it's not severe."

Yichen nodded. Since they were both Mangekyo Uchiha, transplanting eyes from their own clan was indeed not a big problem.

Previously, Shisui Uchiha was also very skilled at using Fugaku Uchiha's Mangekyou Mangekyo, and Susanoo.

Yichen then asked, "Can you assess whether I can use the Kotoamatsukami?"

Sokai closed his eyes, carefully sensed it, and said, "It should be okay."

Yichen nodded in satisfaction and then said, "Alright, come with me to see A-Tu, and then use Kotoamatsukami on him."

Sokai thought for a moment and said, "Is it the White Zetsu clone that was guarding the Ten-Tails' body?"

Sokai, when Zao Jie was working for Yichen, he had met this A-Tu and had a certain impression of him.

Yichen nodded, offered no further explanation, and flew out of Iwagakure with him.

Sokai Yichen hadn't said anything, he probably wouldn't have thought to ask. Even if Yichen had, he probably wouldn't have understood, and then it would have been a hassle to explain it to him.

In his office in the Tsuchikage's Office Building, Ōnoki's seat offered a perfect view of the sky outside the window.

He happened to witness Yichen leaving the village with Sokai, rubbed his head, and muttered, "They really can't stop for a moment."

Yichen flew swiftly with Sokai, easily arriving above the underground base where the Demonic Statue of the Outer Path was located.

"A-Tu, A-Tu, old friends are here!" Yichen shouted to the ground from the Porcelain Platform.

Soon, A-Tu emerged from underground.

It looked at Yichen, who was peeking out from the edge of the Porcelain Platform, and asked, "Tsuchikage, what are you doing here again?"

Yichen laughed and said, "A-Tu, you're being too polite. I'm here to catch up with you, of course."

A-Tu didn't reply; instead, he said directly, "Lord Orochimaru has prepared rent for you."

As he spoke, he tossed a scroll up to Yichen.

Yichen was curious about what Orochimaru would give him, so he used Porcelain Release to receive it and then created a clone to examine it.

The clone opened the scroll and discovered that it contained a complete set of data about Byakugan and Caged Bird.

Yichen had previously obtained some of this data when he was working with Orochimaru, but now Yichen knows that Orochimaru had held back some of it.

After reading the scroll, Yichen asked A-Tu, "Is this a month's rent?"

This time, A-Tu firmly stated, "No, this is a one-time rent payment."

"Lord Orochimaru said that if Lord Tsuchikage is not satisfied, he can do whatever he wants. He doesn't mind."

Yichen remained silent; Orochimaru was far more intelligent than Obito Uchiha.

Obito Uchiha never understood one thing: the reason Yichen created the rent was simply because he couldn't deal with the Demonic Statue of the Outer Path.

If Yichen could truly research the Demonic Statue of the Outer Path, why would he choose to trade with Yichen Obito Uchiha? He would have already stolen it.

Obito Uchiha's mindset was always focused on maintaining their mystery, as were the Black and White Zetsu, both of whom were afraid that others would know of their existence.

Even though Great Ninja Village in the Ninja World knew of their existence, they still instinctively wanted to hide in the shadows.

Especially Black Zetsu, Obito Uchiha had already been exposed, he was even more determined to protect himself and not let himself be seen by others.

Because of this fear, Obito Uchiha was afraid that Yichen would directly expose the location of the Demonic Statue of the Outer Path to the All- Ninja World.

The end result was that they were completely controlled by Yichen.

Orochimaru saw through Yichen's true intentions at a glance. He was not afraid of Yichen doing anything to the Demonic Statue of the Outer Path, nor did he care that Yichen would reveal the location of the Demonic Statue of the Outer Path.

Yichen's smile faded, and he said to A-Tu, "Wait a moment."

Then Yichen pulled his head back in.

After shrinking back, Yichen gave a Sokai to Zao Jie, who had already transformed into his appearance using Transformation Jutsu on the Porcelain Platform.

Sokai nodded, peeking out like Yichen had just done.

When A saw Yichen peek over, he instinctively looked over as well. Yichen wasn't Yichen Uchiha, so there was no danger in making eye contact with him, A-Tu was caught off guard.

Moreover, the two had traded so many times, and Yichen had never laid a hand on him, which made A-Tu less wary of Yichen.

A-Tu looked into Yichen's eyes, and then he saw a pair of scarlet Sharingan. The next moment, he was deeply attracted by the Mangekyo pattern in Sokai's left eye.

A-Tu just stared blankly at Sokai's left eye.

It felt like a long time had passed, yet also like only a moment had gone by. When A-Tu came to his senses, he was somewhat dazed.

He shook his head vigorously, and when he looked up at the sky again, Yichen and Sokai had already flown away at some point.

After thinking for a moment, A-Tu sank into the ground. Soon, many other White Zetsu clone came to A-Tu to ask about the situation.

A-Tu told them that Yichen had agreed to Orochimaru's request and would no longer come to collect rent from them.

The White Zetsu clone talked for a while, and then dispersed.

Other White Zetsu clone naturally went to Snake Pit Village to report the situation to Black Zetsu; A-Tu's task was simply to guard the Demonic Statue of the Outer Path.

A-Tu sat quietly atop the Demonic Statue of the Outer Path, thinking to himself, "Thank goodness, the White Zetsu clone didn't notice anything amiss."

"It shouldn't have delayed the infiltration plan that Lord Tsuchikage personally devised for me."

At this point, White Zetsu perceived himself as someone who was originally a native of Iwa ninja (Iwagakure).

A few days ago, he was transformed into the appearance of White Zetsu clone, replacing one of the original White Zetsu clone clones named A-Tu.

He was ordered by the Tsuchikage to infiltrate the White Zetsu clone and gather information on Black Zetsu and Orochimaru.

In order to successfully infiltrate the village and avoid being exposed, the Lord Tsuchikage even erased his memories of living in Iwagakure and added the memories of the White Zetsu clone, A-Tu.

He would always remember that he was the disciple secretly taken in by the Lord Tsuchikage, and the steadfast inheritor of the Will of Stone.

Today was his first day of infiltration. He had just passed his first test, and the other White Zetsu clone believed that he was one of their kind and had no doubts.

With a good start, A-Tu's confidence grew even stronger. He firmly believed that he would not let the Lord Tsuchikage down.

On the way back to the village, Yichen was a little worried about Sokai's condition, so he asked, "How did it feel when you used Shisui Uchiha's eyes? Do you want me to put a seal on you?"

Sokai was still covering his left eye, panting heavily, and blood was constantly seeping from between his fingers.

After a long while, Sokai finally said, "Teacher Yichen, I was afraid of making a mistake, so I used all my strength when I used the 'Kotoamatsukami' technique."

"In that brief moment, my eye power was consumed at an enormous rate, almost equivalent to several battles using Susanoo."

"I feel like even the long battle I fought with Itachi Uchiha using Susanoo last time wasn't as exhausting as this one."

Yichen asked in surprise, "Can Kotoamatsukami distinguish strength based on the amount of pupil power?"

Sokai Jie nodded and said, "Yes, the more pupil power you have, the stronger the effect and the longer it lasts."

Yichen remained silent, realizing that even the Kotoamatsukami had a limited lifespan.

"By the way, can I still use Kotoamatsukami for a short period of time?" Yichen remembered one of Kotoamatsukami's weaknesses, which was the long interval between uses, so he quickly asked.

Sokai shook his head and said, "It's no use. I used all my strength when I used it before, so even though I've recovered my eye power with Natural Energy, I can't use Kotoamatsukami again for a while."

"I'm not sure when it will be available again."

Yichen nodded, then patted Sokai on the shoulder and said, "The loss of your eye power is nothing. You can just replenish it when you get back to the Land of Snow."

Sokai glanced at Yichen with a hint of resentment, then closed his eyes and began to rest without saying a word.

After returning to Iwagakure, Yichen handed the Sokai over to his Sister Izumi.

Before parting, Yichen told Sokai, "Take good care of your eye power during this time; you still have a mission."

Sokai and Izumi Uchiha both nodded.

After saying goodbye to Sokai and the other two, Yichen then brought over Neji, Katsuya, and Natsuki.

Yichen handed the data Orochimaru had given him to the three of them and said, "Take a good look at this."

Next, the three of you should put aside everything else and focus all your efforts on studying this document.

Katsuya took the data and looked at it, saying, "Orochimaru's experimental data? It seems he was holding back some things from us before. He's really impressive."

"The information he provided before was enough to improve our technology a lot. I didn't expect he had so much more hidden."

Natsuki asked curiously, "Brother, how did you get this scroll? Isn't Orochimaru slapping you in the face?"

Indeed, Orochimaru were full of sarcasm. Despite the supposed fair cooperation, Yichen was completely unaware that his opponent had Mind's Eye him.

Yichen flicked her forehead and said, "Never mind the rest, just focus on your research."

"Neji will be the lead researcher this time. Whatever you two discover, you must make sure Neji understands it."

The three were taken aback. Neji, had his eyes shining brightly. He asked in a trembling voice, "Teacher Yichen, are we going to break the Caged Bird?"

Yichen didn't answer, but said instead, "Don't overthink it, focus on your studies first."

Neji nodded very seriously and said, "Don't worry, Teacher Yichen, I understand."

Yichen did not participate in the research. After sending the three away, he went to find Atsumi Akino.

Atsumi Akino's life was very comfortable. Her main job every day was to first go to the laboratory arranged for her by the Anbu to make Flying Thunder God Kunai, and then check the village's Space-Time Barrier.

She was already very skilled at making Flying Thunder God Kunai, and she could make them very quickly.

Checking the village's perimeter won't take long either.

She spent the rest of her time researching Space-Time Ninjutsu.

When Yichen found her, she was sitting in the Barrier Team office reading a book.

The Barrier Team has the most resources; she comes here to read books, and Barrier Team 've even arranged an office for her.

Yichen gave a hand signal to the Anbu protecting Atsumi Akino, and then entered Atsumi Akino's office.

Upon seeing Yichen arrive, Atsumi Akino quickly said, "Teacher Yichen, you've emerged from seclusion?"

Yichen nodded and asked, "Are you busy?"

Atsumi Akino shook her head and quickly said, "It's nothing, it's nothing."

Seeing her excited expression, Yichen knew that she had been staying in the village for too long and really wanted to go out and play.

Then Yichen said, "Do you still remember that Space-Time Tunnel near Uzushio Village in the Land of Whirlpools?"

Atsumi Akino thought for a moment and said, "Is it that passage that connects to a Gravity Space?"

Yichen nodded and said, "Yes."

Atsumi Akino said, "Of course I remember. That's where I started learning Space-Time Ninjutsu."

Yichen asked, "Is there any way to close that passage?"

Atsumi Akino thought for a moment and said, "Close the passage? Like last time in the Land of Fire?"

Yichen nodded.

Atsumi Akino lowered her head and thought for a while before saying, "I'm not sure. I need to study it carefully. This is a good topic; it's challenging."

"Ever since I learned the Flying Thunder God, I've felt a bit aimless."

Yichen paused for a moment, then asked, "How's the research on Obito Uchiha's spatial dimension going?"

Speaking of the Kamui Space, Atsumi Akino narrowed her eyes and said with a smile, "I've finished researching it."

"I've already been able to enter that space, but I'm afraid to go alone."

"Enter the adventure."

Yichen was overjoyed and said, "That's wonderful! There are many good things in that space."

"Then what are we waiting for? Let's go now!"

Atsumi Akino took a Ninja Tool Pouch from her desk drawer, put it on, and said, "I've prepared everything, just waiting for you to come out of seclusion, Teacher Yichen."

Yichen smiled slightly. It felt so good to not have to do anything himself and to have his disciple do whatever he wanted.

Without these disciples, the Caged Bird would have to be developed on its own, the Kotoamatsukami against White Zetsu would have to be developed on its own, and the power of the Mangekyō Sharingan would have to be developed on its own.

Even Space-Time Ninjutsu needs to be researched by himself; Yichen will probably be exhausted.

And even if you work yourself to death, you won't get much done.

Thinking of this, Yichen suddenly remembered that the new graduating class of the Ninja Academy was about to graduate, and he should find some time to go and see them.

As Naruto and Sasuke grew stronger, Yichen gradually began to consider stopping taking on more disciples.

I was thinking of just teaching those geniuses a little.

At this point, accepting disciples would no longer allow for sufficient time for growth, unlike in Kawakita.

My energy levels won't be as high as they were at the beginning.

But now Yichen has changed his mind; having many disciples is truly beneficial.

He could simply go into seclusion and have his disciples take care of everything; how pleasant that would be!

With this in mind, Yichen left the village with Atsumi Akino.

In Ōnoki's office at the Tsuchikage's Office Building, Ōnoki glanced at the departing figure in the sky outside the window, rolled his eyes, and without saying a word, continued to handle his official business.

Instead of teleporting directly, Yichen and Atsumi Akino chose to fly.

On the way, Yichen chatted with Atsumi Akino about some basic knowledge of Space-Time Ninjutsu.

After Yichen fused with the Light Release, he felt his intelligence had also improved, so he wanted to try to learn the Flying Thunder God.

Even though Atsumi Akino spoke earnestly the whole way, Yichen still felt completely lost and didn't understand a thing.

Yichen shook his head. It seemed he really wasn't suited to learning the Flying Thunder God Technique. This wasn't a matter of intelligence, but rather a matter of talent.

After arriving at the Land of Fire, Yichen stopped thinking about learning the Flying Thunder God Technique.

He and Atsumi Akino looked around together.

Yichen exclaimed, "The environment in the Land of Fire is truly wonderful. It hasn't been long, and this battlefield we ravaged is already covered in green again."

Atsumi Akino nodded in agreement, saying, "Teacher Yichen, is there any hope that the village can train Wood Style Ninja?"

"If the Wood Style Ninja plant more trees, it should change the land conditions of the Land of Earth."

Yichen thought for a moment and said, "There is hope, but it involves risks, and I don't have any plans in that regard right now."

Yichen was naturally referring to Sokai and Izumi Uchiha. The success rate of Mangekyo Uchiha transplanting the First Hokage's Cells was definitely higher than that of ordinary people.

However, Yichen only had two experimental subjects, and he could not accept any failure.

Therefore, Yichen preferred to let Sokai and the other go to the underground Natural Energy in the Land of Snow to slowly recover their pupil power, rather than risk transplanting the First Hokage's Cells into them.

Atsumi Akino nodded. She didn't ask any more questions, but instead closed her eyes and sensed the Flying Thunder God Coordinates left in the Kamui Space.

Atsumi Akino quickly Awakening Eyes and said, "Found it."

After saying that, she took out the materials from her Ninja Tool Pouch and began to set up.

She set up a barrier specifically designed to enhance Space-Time Perception. This was also the result of her research in her spare time.

She stood within the barrier and Yichen said, "Teacher Yichen, I'm ready. I'm about to teleport."

Yichen nodded, walked to her side, and put his hand on her shoulder.

Atsumi Akino Hand Seals hand Hand Seals, this time more than ever before.

After Atsumi Akino finished the hand seals, Yichen and she disappeared from the Ninja World.

Yichen felt a moment of dizziness, which seemed to last longer than before, yet also seemed to have no effect at all.

When Yichen regained his senses, he had already appeared in the Kamui Space.

Beside Yichen's feet was a metal plate with a pattern of a Great Fireball engraved on it.

It was the Flying Thunder God Mark that Atsumi Akino had thrown in last time.

Atsumi Akino said, "Teacher Yichen, we're in. Is there any danger here?"

Yichen said, "Don't worry, there aren't many people here, and those people aren't around here either."

Yichen watched as Atsumi Akino threw the metal plate in.

Therefore, using the Great Fireball pattern on the metal plate as a reference, Yichen knew the approximate direction in the Kamui Space.

After discerning the situation, Yichen led Atsumi Akino in a certain direction.

The scenery in the Kamui Space was all the same, and fearing that they would get lost, Yichen would have Atsumi Akino place a Kunai engraved with the Flying Thunder God symbol at regular intervals.

This is both to make it easier to find your way back if you get lost, and to facilitate location tracking.

After a long while, Yichen stopped flying and said to Atsumi Akino, "Akino, try to sense the Flying Thunder God Coordinates in the Ninja World from here."

"Hmm." Atsumi Akino sat on the Porcelain Platform and began to sense.

She thought it would take a long time this time too, but she opened her eyes shortly after closing them.

She exclaimed in surprise, "Teacher Yichen, I sensed it! There are many Flying Thunder God Coordinates in the Ninja World on the other side!"

Yichen breathed a sigh of relief; it seemed he hadn't gone to the wrong place. Yichen explained, "The village is right across the street. Let's get out of here first."

"Hmm." Atsumi Akino left a few Flying Thunder God Kunai on the spot, and without setting up a barrier to enhance the senses, she directly teleported back to the Ninja World with Yichen.

Yichen's vision went dark for a moment, then brightened again, and the next moment, he found himself in a house.

Looking at the various items with the Flying Thunder God symbol hanging on the walls of the house, Yichen recognized that this was where Atsumi Akino usually conducted her experiments.

Upon hearing the commotion, a team of Anbu immediately rushed in.

This area was originally the territory of the Anbu, Atsumi Akino's laboratory was a high-level forbidden area within the Anbu.

Even though there was no one inside, the noise alerted the nearby Anbu on duty.

Yichen made a series of hand gestures, confirmed his identity with the Anbu, and then sent the person away.

Then Yichen asked Atsumi Akino, "Are you tired? Do you want to rest for a day?"

Atsumi Akino nodded and said, "Okay."

Although she was only teleported twice, it was an interdimensional teleportation, and she was also carrying someone with her, which put a lot of pressure on Atsumi Akino's physique.

After leaving Atsumi Akino's laboratory, Yichen went to the Barrier Team alone again, this time looking for Kawazoe Yura.

Kawazoe Yura is currently the second-in-command of the Barrier Team, while the leader is Uzumaki Yumi.

The former members of the Barrier Team have either retired or been reassigned to research the Little White Ball.

When Yichen met Kawazoe Yura, she was discussing some things about the research on the Little White Ball with Uzumaki Yumi.

The main force behind the research on the Little White Ball came from the Barrier Team, and both of them were involved.

Just as Yichen was about to speak, he suddenly froze, because he noticed that Uzumaki Yumi was heavily pregnant.

Yichen blinked a few times and asked, "Yumi, are you pregnant?"

Hearing the voice, the two quickly looked up and saw Yichen. Uzumaki Yumi nodded and said, "Lord Tsuchikage? Yes, I'm six months pregnant. Didn't Ikura tell you?"

Ikura and Uzumaki Yumi are considered to be in Marriage alliance, and they had already considered having children back when Naruto and the others were born, but they postponed it until now.

It's not early for either of them, considering their age. After all, people like Yichen who are always busy with work are rare.

Kawazoe Yura then asked, "Teacher Yichen, are you here to see Akino?"

In recent years, Yichen has rarely come to the Barrier Team because of Sealing Jutsu. Most of the time, he comes to the Barrier Team to discuss Space-Time Ninjutsu with Atsumi Akino.

Yichen shook his head and said, "I've already spoken to her and assigned her a task. This time, I'm here to see you."

Upon hearing this, Uzumaki Yumi got up and tried to leave.

Yichen waved his hand and said, "It's not a confidential matter."

"Yulan, you previously developed a barrier to block the Byakugan's X-ray vision."

"Is it possible to develop a barrier with even better shielding effects?"

Kawazoe Yura asked in surprise, "You want to block Dōjutsu that's even better than the Byakugan's X-ray vision?"

"Does this kind of Dōjutsu exist in the Ninja World?"

Yichen said, "There should be one, and it's many times more powerful than the Byakugan."
