Warlock Invasion of Naruto.

This serves two purposes: firstly, it declares to outsiders that Kushina is the true leader of the Uzumaki clan; secondly, and more importantly, it keeps Konoha in suspense, preventing them from easily achieving their goals even if they intend to cooperate with Konoha, thus maximizing Konoha's own gains.

Of course, Kushina was somewhat familiar with these roundabout negotiation methods, but she was still not used to them.

"That guy Bai Yu is really too much! He went out with me without me!" Kushina pouted, feeling a little dissatisfied.

Although she knew that the Uzumaki clan had to leave people behind to guard the area, she couldn't help but feel a little emotional.

Bai Yu went out and took Taiichi and Mitsuko with him, which made Kushina feel much more relaxed. However, the Nine-Tails' clone also went to the sea to train, and with no one to talk to, Kushina felt very bored.

After marrying Shiraha, and especially after having children, Kushina had relatively less time for training.

However, her progress was not affected or slowed down by this; on the contrary, it accelerated.

Because the Nine-Tails' chakra clones could train alongside Kushina's shadow clones, practicing various powerful ninjutsu on the East Sea.

As Mito's seal gradually disappeared, Kushina's mastery of the Nine-Tails' chakra deepened, and her body continuously adapted to and was transformed by it.

Although she is still a long way from fully mastering all of the Nine-Tails' chakra, her current strength is even slightly inferior to Bai Yu's, so she can train slowly.

Kurama was initially reluctant to train with Kushina's shadow clone, but Bai Yu gave it a choice: either take care of the child or go train. Kurama decisively chose the latter.

There was no other way. When it was with Kushina, it could still throw a tantrum and argue. But when it was with Taichi and Mitsuko, those two demon kings, it couldn't hit them or scold them. They even treated it like a dog, making the strongest tailed beast lose all its dignity. So Kurama preferred to train.

"I really want to go out too!" Kushina looked at the document filled with text, angrily put down her pen, and vigorously rubbed her smooth and beautiful long red hair. However, she suddenly remembered what Bai Yu had said before: as long as she raised the two children as soon as possible, she could officially retire.

Thinking of this, Kushina grabbed the pen, gripped it tightly, and then fiercely signed her name on the document, thinking to herself that she would definitely make Bai Yu pay when she got back this time.

At this moment, her gaze drifted to the smooth tabletop and the large sofa beside her. Her eyes were somewhat unfocused. Thinking of the scene of her previous 'disastrous defeat', her cheeks quickly became hot and flushed.

Boom boom boom!

At that moment, there was a knock on the office door.

Although the voice was very soft, it still startled Kushina. The indescribable images in her mind vanished instantly, and she said guiltily, "Come in."

"Teacher Kushina, this is a new drug formula recently developed by the hospital, and also the accounts sent by the Snake Spirit Group. Please review them... Why is your face so red?"

Wearing a white lab coat, Nohara Rin walked into the office carrying a large stack of documents, explaining the situation to Kushina as she went. However, when she reached the desk, she noticed that Kushina's face was flushed, like a ripe tomato.

"Ah? Maybe it's a bit hot." Kushina immediately put on a serious face. Although she often showed a childish and immature side in front of Shiraha, she was quite serious in front of others, especially Rin, who was her disciple. Kushina usually maintained the dignified demeanor of a teacher.

"Just put the documents aside, I'll take care of them," Kushina added, pointing to an empty corner of the desk.

"Yes, then I'll go back to work on the hospital matters. Teacher, please take care and rest. Don't overwork yourself. I'll come back to help you after I'm done with the hospital work." Nohara Rin put the documents away, smiled, bowed slightly, and left.

"Lin has grown up too."

Kushina watched Rin's retreating figure and couldn't help but sigh at how quickly time had passed. Rin had now basically mastered the power of the Three-Tails, Isobu. Of course, the main reason was that Kurama, the leader, was quite capable. Isobu was very cooperative and didn't cause any trouble during Rin's process of familiarizing herself with the Tailed Beast's chakra.

Unfortunately, Rin does not have a special physique like Senju or Uzumaki, so she cannot fully unleash the power of the Three-Tails Isobu. However, even so, the young Rin is able to borrow the Three-Tails' chakra to enter a half-tailed beast state, and ordinary Kage-level powerhouses are probably no match for her.

Lin is a kind-hearted person who doesn't like fighting and is content with having some self-defense capabilities.

"Kakashi hasn't visited Rin in a long time," Kushina thought to herself. Personally, she still hoped that Rin could stay with her. She liked this organized and capable disciple very much.

Of course, she also hoped that Lin could be happy.

"If Kakashi agrees to marry into the Uzumaki clan, I could try to match them up." Having come up with a suitable solution, Kushina felt a sense of relief. Returning Rin to Konoha was absolutely impossible, but if Kakashi was willing to marry into the Uzumaki clan, she could accept it. She knew Kakashi quite well, and overall, he seemed quite suitable for Rin.

On the other side, after leaving the office, Lin went straight downstairs and headed east onto the street, preparing to return to work at Vortex Hospital.

However, she did not notice that in the shadows of the tall building behind her, a ninja dressed in a black robe and wearing a swirling mask was spying on her.

"It really is Lin! Lin didn't die?!"

Obito's eyes were filled with shock. His emotions were out of control, and his Sharingan instantly appeared. His other eye also turned into the Mangekyou Sharingan pattern.

Just before, when "Kodama" snatched Rin's "body", Obito had a sliver of hope in his heart, because he felt that although Rin had been stabbed in the heart by Kakashi with a ninja sword, she had not died immediately, so after being rescued by Kodama, she might still have a chance to survive.

Especially when Kodama saved the seriously injured Yahiko, Obito's idea became even more uncontrollable, but Black Zetsu's reminder made his hope seem slim.

Later, when Kirigakure invaded the Uzumaki clan, Obito learned that Kodama and the Uzumaki clan had a cooperative relationship. In particular, Kodama was even thinking of facilitating cooperation between Akatsuki and the Uzumaki clan to abandon the idea of ​​capturing the Nine-Tails Jinchuriki. This made Obito feel that the relationship between Kodama and the Uzumaki clan was definitely not as simple as so-called cooperation.

Jue had repeatedly infiltrated the Uzumaki clan, but was blocked by the barrier each time, so he knew very little about the Uzumaki clan's internal affairs.

However, when Obito infiltrated Konoha, he discovered something: in the previous few years, Kakashi would visit the Uzumaki clan every so often.

Even after the relationship between the Uzumaki clan and Konoha deteriorated, he remained the same.

As far as Obito knew, the Konoha leadership would not tolerate the Uzumaki clan becoming too powerful.

Kakashi joined the Anbu and became the Third Hokage's direct subordinate, yet he still went to the Uzumaki clan. It couldn't possibly be to catch up with Shiraha and Kushina there.

Therefore, Obito decided to personally infiltrate the Uzumaki clan to check the situation, because even the most solid fortress has its cracks.

Although the Uzumaki clan still possesses a barrier capable of restricting spatial abilities, as Obito's strength increased and his body fully adapted to Hashirama's cells, he discovered that the power of his Mangekyou Sharingan also increased.

To be on the safe side, Obito waited until Hakuba arrived in Konoha before finally starting his own operation. Obito was still very wary of Hakuba, who had once seemed like an ordinary medical theory teacher.

Obito first used his eye technique to control a Uzumaki ninja who was out, and then entered Konoha through his perspective.

However, to his surprise, through the perspective of the Uzumaki ninja, he discovered that Rin was still alive.

Obito completely lost his composure. He used Kamui's spatial abilities to sneak into the Uzumaki clan's territory through the gaps in the barrier where the Uzumaki ninjas were entering and exiting, and finally saw Rin with his own eyes.

Five years later, Lin is even more beautiful and stronger than before.

Through the Six Paths Technique left by Madara, Obito was able to sense that Rin's body contained an extremely powerful chakra.

Remembering that she had been controlled by the Hidden Mist ninja and had the Three-Tails transplanted into her body, Obito instantly understood everything.

Rin has become the Jinchūriki of the Three-Tails and has also taken control of its power.

At this moment, Obito also understood what had happened before and why Kakashi wanted to 'kill' Rin.

To be precise, the question is why Rin deliberately ran into Kakashi's ninja sword and chose to commit suicide.

Obito previously thought that Rin didn't want to be a burden or a liability to Kakashi, so she chose to commit suicide to free Kakashi. At the same time, she wanted to protect the damned Konoha and prevent the Three-Tails from going out of control when near Konoha.

It was this damned ninja world, these damned five great nations, that made Rin make such a painful choice.

Even after understanding all of this, Obito still couldn't forgive, so he chose to continue carrying out Madara's plan to completely eliminate the war and allow everyone to meet in a dream world where there is only peace.

However, Obito was deeply moved when he discovered that Rin was still alive.

"Are you trying to take Lin away? But she seems so happy now. Is she still my Lin?"

As Obito watched Rin disappear from sight, he was lost in deep confusion.

He wavered.

"It seems like Black Zetsu shouldn't know about this..."

Obito fell into deep thought.

......

half a month later.

The third round of the Chunin Exams in Konoha finally began amidst much anticipation.

Meanwhile, at the Akatsuki organization's stronghold in Amegakure.

Obito is giving orders to Zetsu.

"Bai Yu has been in Konoha for too long. He wouldn't waste so much time just for the Chunin Selection Exam. You'd better continue to infiltrate Konoha to monitor him. Also, the Uchiha clan is a key part of our plan, and we can't afford any accidents."

“This is indeed very suspicious. As for monitoring the Uchiha, couldn’t we just have a clone do it?” Black Zetsu said in a deep voice. “Yagami Shiraha has special sensory abilities. It’s not an easy task to monitor him.”

"It's precisely because it's not easy that we need you to do it," Obito said calmly.

"You really know how to boss people around," White Zetsu couldn't help but retort. "And what about you?"

"I'm going to investigate Kodama. That guy is too suspicious. I'm going to investigate the Infinite Ring Organization's stronghold," Obito said in a deep voice.

"You've discovered the Infinite Ring's stronghold?"

Black Zetsu's voice carried a hint of surprise, because even he and White Zetsu had not discovered the Infinity Ring's stronghold. It seemed that Obito's spatial abilities were even more powerful than he had expected.

“It’s just a suspected base; I need to investigate,” Obito explained.

White Zetsu's true form pressed on, "Where is it?"

“Near the Uzumaki clan,” Obito added, then fell silent.

"No wonder you asked us to monitor Yagami Shiroha." Black Zetsu realized that it was safest to go and investigate while Yagami Shiroha was away from the Uzumaki clan's territory. Otherwise, it would be quite dangerous if they encountered Yagami Shiroha and Uzumaki Kushina.

The strange sealing techniques and barriers used by Kirigakure during their previous battle with the Uzumaki clan left a deep impression on Black Zetsu, and he instinctively sensed danger.

The reason he was able to lie low for so many years was because of his caution.

Obito said, "When Yagami Shiroha returns, you must come back and inform me immediately."

"Understood, we will handle this matter well." Black Zetsu responded, then he and White Zetsu disappeared underground and quickly moved away using the Mayfly Technique.

"Perhaps, Rin will understand me. She has always understood me." Obito's soft murmur echoed from the dark hideout.

The next second, faint ripples appeared in the space, his figure began to twist, and then he disappeared completely.

......

On a hilltop not far from the Uzumaki clan's territory, two ninjas dressed in long robes with black backgrounds and red clouds appeared.

"Ban, is this the place you're talking about?" One of them had long, flowing red hair, a thin build, and strange, pale purple concentric circles in his eyes. He was Nagato, whose legs had been healed by Kodama.

It's unclear how Obito persuaded Nagato, but the two of them ended up coming to the Uzumaki clan's territory together.

"Hmm." Obito, standing next to Nagato, responded in Madara's distinctive tone.

"What a powerful barrier! It even covers the underground." Nagato observed the Uzumaki clan's territory through his Rinnegan and discovered that the entire territory was covered by an invisible barrier. Even he, who had mastered most of the Rinnegan's abilities, found it extremely troublesome.

"Is this the Nine-Tails' chakra? It's so powerful!" Nagato continued to sense and finally discovered the incredibly powerful chakra at the center of the Uzumaki clan's territory.

In his perception, the Nine-Tails' chakra was as dazzling as a spotlight in the night and as fiery as a raging flame.

"It seems I underestimated the power of the Nine-Tails," Nagato said, looking down with a slight frown.

As he became more familiar with the Rinnegan's abilities, under Obito's guidance, he completely regarded himself as the reincarnation of the Sage of Six Paths, and his mindset began to shift from human to 'god'.

"If I were in my prime, the Nine-Tails would be nothing more than a plaything in my hand. But now, with your Rinnegan, dealing with the Nine-Tails shouldn't be difficult," Obito said casually, using Madara's tone to sound arrogant.

Although he didn't know exactly how strong Madara was, according to Madara's description, Kurama's strength was quite average, and it could be easily controlled by the Eternal Eye.

Now that Nagato possesses the Rinnegan, his ability to suppress Kurama is even stronger.

What's more, he was there to support us.

"Let's try negotiating first. If the Nine-Tails Jinchuriki is willing to cooperate, then the difficulty of carrying out the plan will be greatly reduced." Nagato maintained his condescending attitude: "If possible, I don't want to use violence."
