Ch.253 Restarting the Rinnegan Plan!

It didn't take long for Shinji to notice the village's adjustment in surveillance.

He could sense that the village's monitoring of Sasuke was still very strict, but the surveillance on him, as well as Karin, Kimimaro, and Haku, had been significantly relaxed.

Especially Karin.

Due to Shinji's instructions, she had recently returned to her low-profile state. Additionally, Jiraiya, who had brought her to the village, had visited her a few times, so the village's surveillance on her had been almost completely lifted.

Similarly, Yūgao Uzumaki's surveillance had also been completely removed.

However, according to Tsunade's request, Yūgao still needed to report to the Konoha Hospital daily for comprehensive medical check-ups.

Everything seemed to be returning to normal!

That night.

Shinji put on his Akatsuki robe and mask, then quietly infiltrated Karin's apartment.

Since they had previously communicated through 'Jikibi,' Karin had been waiting in her apartment. When Shinji arrived, she quickly greeted him and bowed. "My lord!"

Shinji nodded and asked, "Have there been any changes in your body recently?"

Karin immediately took out a small notebook and handed it to Shinji.

The notebook contained detailed records of her daily physical changes, such as whether her chakra had increased, the recovery of her skin in the transplanted areas, and so on. Everything was meticulously documented.

Shinji quickly skimmed through the notebook and fully grasped Karin's condition over the past few weeks.

Undoubtedly.

As Karin continued to fuse with the White Zetsu cells and her body matured, her chakra had been steadily increasing.

This was consistent with Shinji's assessment when he extracted Karin's chakra through 'Wazunagi.'

However, at Shinji's level, a mere increase in chakra volume was no longer sufficient. What he needed was an improvement in the quality of Karin's Yang Release chakra.

Next, Shinji briefly inquired about Karin's progress in training 'Wood Release.'

Karin looked ashamed. "I'm sorry, I still can't use 'Wood Release' through chakra nature fusion."

After transplanting and gradually fusing with the White Zetsu cells, Karin, like Obito, had gained the ability to activate 'Wood Release' using the White Zetsu cells.

However, using 'Wood Release' in this way required activating, or even indulging, the White Zetsu cells within her body.

Although the White Zetsu cells had been modified and were not as aggressive as the First Hokage's cells, they still had the ability to devour normal cells. Therefore, activating 'Wood Release' by stimulating the White Zetsu cells was essentially allowing them to run rampant in her body.

This was extremely dangerous, which was why even Obito, who possessed the Mangekyō Sharingan capable of balancing the White Zetsu cells, rarely used 'Wood Release.'

Thus, to safely use 'Wood Release,' one had to master the fusion of Water and Earth chakra natures, synthesizing 'Wood Release' through one's own chakra.

Of course.

The orthodox method meant there were no shortcuts, which was why, apart from the First Hokage, no one in the shinobi world had successfully achieved this.

Shinji waved his hand. "You don't need to apologize. I had you train in 'Wood Release' to improve your chakra control."

"Yes, I will definitely work harder!"

Karin looked at Shinji with determination in her eyes.

For her, meeting the leader and joining the Akatsuki marked the beginning of her life. Before that, her life had been aimless. So, for the Akatsuki, she was willing to dedicate everything, including her life.

Shinji nodded slightly, then took out a small nutrient tank from his ninja tool pouch. Floating inside the tank was the pair of severely damaged Mangekyō Sharingan eyes that he had previously attempted to restore using Karin.

Karin glanced at it and immediately understood Shinji's intention.

However, restoring eyes was something she was already familiar with, so she wasn't nervous.

On the contrary, through the process of restoring eyes, she found that her Yang Release chakra had become more refined. This was because restoring damaged Mangekyō Sharingan required infusing a large amount of Yang Release chakra into them daily, and this process itself was a form of training for her Yang Release chakra.

After preparing the surgical tools, Shinji said, "The Hidden Leaf's investigation of you has ended. As long as you keep a low profile, neither the Hidden Leaf nor the Grass Village will focus their attention on you. This gives us the perfect opportunity to attempt to restore this pair of severely damaged Mangekyō Sharingan."

Karin listened attentively and nodded repeatedly.

Shinji continued, "Your Yang Release chakra has significantly improved compared to before. This time, our chances of success are quite high."

Karin quickly replied, "I will definitely do my best! And please rest assured, I've been secretly practicing living without using my eyes these past few days. I've made some progress, so after transplanting this pair of severely damaged Mangekyō Sharingan, I won't be discovered!"

Shinji was slightly surprised. He hadn't expected Karin to be so meticulous as to practice this. He smiled and said, "Very good!"

Karin's face lit up with joy.

The leader's approval made her feel that all her efforts were worth it.

Soon, Shinji began the surgery.

The process of the surgery need not be described in detail. Moments later, Karin sat up from the bed. "My lord, I feel a sense of familiarity with these eyes!"

"Hmm."

Shinji nodded lightly.

Restoring damaged Sharingan eyes was almost equivalent to giving them new life.

This characteristic had already been clearly demonstrated when Karin restored the pair of half-damaged Mangekyō Sharingan.

It was precisely because damaged Sharingan eyes could be reborn that Shinji had initiated his 'Rinnegan Plan.'

Based on this characteristic, once Karin restored the pair of severely damaged Mangekyō Sharingan, she would essentially become half of their original owner.

This meant that Karin had met the basic conditions for fusing another pair of Mangekyō Sharingan and attempting to achieve the Eternal Mangekyō Sharingan.

Of course, this was still just Shinji's speculation.

But if Karin succeeded in this step and truly fused a pair of Eternal Mangekyō Sharingan through her own body, then, in theory, she would be the perfect experimental subject for achieving the Rinnegan!

Moreover, Shinji had a backup plan. If Karin failed at the step of fusing the Eternal Mangekyō Sharingan, he could use 'Susanoo Tomoshibi' to forcibly fuse a new pair of Eternal Mangekyō Sharingan, using the restored severely damaged Mangekyō Sharingan as the main body.

At that point, although this new pair of Eternal Mangekyō Sharingan wouldn't have been fused by Karin herself, the main body would still be the restored severely damaged Mangekyō Sharingan. She would at least be considered a quarter-owner of this new pair of Eternal Mangekyō Sharingan and could still attempt to achieve the Rinnegan...
