Konoha: Starting with a sign-in for Hashirama cells

Gradually, these incantation patterns faded away, not disappeared, but were hidden in the subcutaneous tissue.

“As you can see, I copied the One-Tailed Chakra and made it my own ability,” Naruto said.

"Now, I can selectively extract the chakra of the One-Tailed Beast, or you could say that I am the One-Tailed Beast."

"..." Kaguya.

"Really?!" Black Zetsu stared in disbelief.

"Was Hamura's chakra copied using this method?" Kaguya finally solved this mystery.

“Yes,” Naruto replied.

"Anything can be copied. The stronger the copying ability, the longer the cooldown time will be."

"That's my answer. If you're satisfied, please teach me."

Kaguya was silent for a moment before speaking, "I have never taught anyone this ability that comes naturally from eating fruits, and I don't know how to teach it."

"So, you mean you're going back on your word to repay me for the previous times you deceived me?" Naruto remained silent.

“No, I’m not like you,” Kaguya said. “Give me control of your body, and I’ll demonstrate. How much you learn depends on your own abilities.”

“I don’t like playing with fire,” Naruto said.

"I don't need all of it, just give me control over a portion," Kaguya said.

That's something to consider, but can he adjust and control the magnitude of the rise and fall himself? Naruto was uncertain about this.

After patiently waiting until breakfast was finished, Naruto activated the Flying Thunder God Technique and went to the depths of the deserted mountains to try to loosen his control over Kaguya.

Upon realizing she could control her right hand, Kaguya thought for a moment, then channeled a large amount of chakra to create an expanding Truth-Seeking Ball.

"..." Naruto.

Chapter 158 Black Zetsu's Escape

“This thing… I can’t learn it right now. Let’s find something simpler,” Naruto said.

"Choose whatever you want? Is that a rule in the transaction?" Kaguya retorted.

"You said you wanted to learn all my abilities, so don't be picky."

"Who knows if what you mean by copying and the cooldown time is true? If you're lying to me and keep copying my abilities, I'll be at a huge disadvantage, and I won't be able to punish you."

"This is it, take it or leave it."

"..." Naruto.

Is the Expanding Seeking the Dao Jade something he can approach at this stage?

This is an even more terrifying, world-destroying ultimate technique than Infinite Tsukuyomi.

Infinite Tsukuyomi is merely an illusion and will not cause harm to people or the environment.

The Expanding Seeking the Way Jewel possesses the property of obliterating everything, reducing the world to nothingness; its volume exceeds that of an ordinary Seeking the Way Jewel by countless times.

Ordinary Seeking Truth Jewels can be used for offense, defense, and healing, and have a variety of uses.

The Expanding Seeking Jade, on the other hand, doesn't have many fancy features; it has only one function: annihilation.

It seems that apart from its large size, it is no match for a regular Truth-Seeking Ball.

It cannot change shape, cannot move, consumes terrifying amounts of chakra, expands slowly, and has a whole host of drawbacks. It doesn't feel as useful as a regular Truth-Seeking Ball.

“Hamura…that is, your fiancée,” Kaguya said.

"The Truth-Seeking Balls she used were effective against Bloodline Limits, Yin-Yang Release of the Rinnegan, Sage Chakra, and Tailed Beast Chakra."

"It is either ineffective or cannot achieve good results, unlike its overwhelming advantage over other substances."

"This expanding Seeking Dao Jade, no matter what it is, can devour it completely and annihilate it into nothingness."

Living inside Naruto's body, seeing what Naruto sees, and with Black Zetsu's guidance, Kaguya understands a lot and is able to better integrate into this era.

"You mean, the Expanding Truth-Seeking Ball, like the All-Killing Ash Bones, can kill a Six Paths level powerhouse?" Naruto asked.

"Six Paths Level Powerhouse..." This was the first time I'd heard this term, but it was easy to understand, Kaguya said.

"Different."

"Killing the ashes together can only extinguish life and sever the life force; it does not harm the soul."

"The expanding Truth-Seeking Ball contains life, chakra, soul, everything, everything."

"If you're so powerful, why were you sealed away by Hagoromo and Hamura back then?" Naruto asked.

"You know a lot..." Kaguya said quietly, "What I wanted was to reclaim my chakra, not to kill Hagoromo, Hamura."

Killed by the All-Killing Ash Bones, the person's body was destroyed, leaving only their soul, which could no longer provide chakra.

Chakra requires a perfect combination of spiritual energy and physical energy to be refined.

Being killed by an expanding Truth-Seeking Ball is even worse; it wipes you out completely, leaving nothing behind.

Naruto understood. This expanded Truth-Seeking Ball was far more powerful than a regular Truth-Seeking Ball. He had to learn it, no matter what.

"One last question, can this expanding Truth-Seeking Ball obliterate you?" Naruto asked.

“No,” Kaguya said.

Okay, Six Paths, Earth Explosion Star is even more awesome.

Naruto cleared his mind of distractions, turned his gaze, and carefully observed the expanding Truth-Seeking Ball in front of his right hand, which was several times larger than a basketball and was still growing.

“Mother, I will find a way to save you,” Hei Jue said.

“My consciousness is trapped within this chakra, limiting my movement, so I can’t offer you much help,” Kaguya said.

"The only thing I can freely use is the chakra I obtained from the previous vessel. I'll give it all to you."

"I need to find a powerful vessel to possess. The amount of chakra must be large so that more of it can be converted into my chakra."

"Mother's chakra!" Black Zetsu exclaimed in surprise, then laughed, "In that case, I'll be even more confident."

“Go,” Kaguya said.

There are two aspects to consider when learning Black Zetsu.

On one hand, it is Kaguya's consciousness.

On the one hand, it has become an independent entity.

They can be combined, or they can be separated.

It can be one, or it can be two.

When Naruto completely immobilized her, Kaguya couldn't do anything. Now that she can control her right hand, she has a little more freedom to act, and her opportunity has arrived.

The jet-black Black Zetsu, carrying some of Kaguya's chakra essence that Kaguya had absorbed from Sasuke, was sent out by Kaguya and perfectly integrated into the equally jet-black, expanding Truth-Seeking Ball.

As the bottom of the expanding Truth-Seeking Ball touched the ground, Black Zetsu silently burrowed into the earth.

Black Zetsu has no soul, is not alive, and its chakra belongs to Kaguya; it is the most powerful chakra.

Therefore, all sensory abilities are ineffective against it.

Even powerful figures like Hagoromo and Hamura couldn't detect Black Zetsu when they sealed their mother.

Black Zetsu's ability to conceal himself is evident.

Having successfully sent Black Zetsu away, Kaguya felt a sense of relief, seeing a glimmer of hope for escaping her predicament.

Suddenly, his right hand was immobilized and could not be moved.

“Chaos, darkness, I can’t see anything,” Naruto said. “It’s too advanced for me. I have to start learning from scratch.”

If you can't even understand it, let alone comprehend, learn, or use it.

Naruto formed hand seals, creating the Multiple Shadow Clone Technique, thousands upon thousands of shadow clones appearing amidst the smoke: "Based on earth and water, I will begin to fuse other nature transformations."

"Fusion... You want to master the Bloodline Limit on your own," Kaguya said.

"Is that not okay?" Naruto asked.

“Bloodline Limits are abilities that cannot be learned,” Kaguya said.

"At most, you can only fuse externally to form ordinary Truth-Seeking Balls. That's what you ninjas call ninjutsu, not bloodline limit."

"That's enough. I'm not trying to get rich overnight," Naruto said. "Let's take it one step at a time."

Kaguya fell silent and stopped speaking.

Out of boredom, I observed Naruto's life while also wondering how Black Zetsu was doing, hoping things were going well.

~~~

"Faster! Faster! Faster!"

Black Zetsu was desperately fleeing.

It is the mother's only hope, and it must not be lost.

In my perception, my mother's chakra is getting further and further away.

“Madara is the most suitable vessel for possession; no one is better than him,” Black Zetsu thought to himself.

To perfectly revive Madara, one must possess the Rinnegan.

There are three people known to possess the Rinnegan: Naruto, Sasuke, and Nagato.

Needless to say, Black will not approach anything or anyone related to Naruto until he has enough power.

“Nagato…” Black Zetsu thought to himself.

“In the past, I was unable to control people stronger than me. When my mother created me, I was already sealed away and unable to give me any power.”

"Now, with my mother's chakra, with assistance and enhancement, I can do it."

After traveling underground for two days, they finally arrived at the Land of Rain.

Ordinary people cannot find Nagato, nor do they know that Nagato even exists.

Black Zetsu knew perfectly well that Obito often went to see Nagato. It quietly came to Nagato's location and slowly attached itself to him without making a sound.
