Unaware of the Treasure Mountain

"Mom... Kushina is actually this strong?!"

Naruto looked astonished because he saw Kushina fighting Nagato in Issei's (Shiraha's ) memories. Kushina's heroic figure was imprinted in Naruto's heart, but he realized that the Kushina from another world had nothing to do with him.

It's important to know that the prerequisite for his victory over Nagato was obtaining information that his master Jiraiya risked his life for, as well as the initial delaying efforts of other ninjas in Konoha.

Even so, he was ultimately no match for Nagato. It was only because Hinata fought desperately to protect him that he unleashed the Nine-Tails Chakra in a state of irrationality, thus breaking free from Nagato's control. With his father's help, he regained his senses, re-entered Sage Mode, and defeated all Six Paths of Pain.

Judging from Kushina's appearance, her strength is no less than Nagato's, and she controls the power of the Perfect Nine-Tails.

"I never imagined that Kushina from another world was so amazing, able to persuade another version of me," even the Kurama inside Naruto couldn't help but exclaim.

The reason Naruto was able to use his Chakra was not only because of the reconciliation between the two sides, but also mainly because Naruto was the reincarnation of Asura's chakra and possessed the power of the Sage of Six Paths.

Otherwise, the Chakra of the strongest Tailed Beast is not something an ordinary person can withstand, not even half of it.

Kushina from the other world, despite lacking the chakra of Indra and Asura's chakra, was able to control the power of the Perfect Nine-Tails, which is truly impressive.

"As expected of the Red Hot Habanero!" Naruto said with a smile. Kushina's current strength is even greater than his strength at the beginning of the Fourth Shinobi World War.

As for their strength in the final battle, it wasn't acquired through their own training. It was because he and Sasuke each received the Sage of Six Paths Six Paths Yang Power and Six Paths Yin Power from the Sage of Six Paths, which fully activated the power of Asura and Indra's Chakra within their bodies.

After losing their arms at the Valley of the End, the two also lost the Six Paths Yang Power and the Six Paths Yin Power. If they were to encounter Six Paths Madara now, they would probably find it difficult to withstand him.

Fortunately, the Otsutsuki Clan Member they encountered, while possessing immense Chakra comparable to Madara Uchiha in Six Paths Madara, were not particularly strong in actual combat.

The arrogance of the Otsutsuki Clan can be a major disadvantage in battle, at least when the strength of the two sides is not overwhelmingly superior.

However, they were still uncertain about the true strength of the enemy leader, Jigen, since they did not know the Kara that they had encountered, which was suspected to be a remnant of the Otsutsuki Clan.

Whether it was when they joined forces to fight against Momoshiki and Kinshiki of the Momoshiki Otsutsuki, or when Sasuke and Boruto faced Urashiki, they almost always won by a narrow margin.

Given the cautious nature of the Kara, if they were to encounter an Otsutsuki Clan Member with Chakra as powerful as Six Paths Madara, and who was also inherently cautious, it would be very difficult for Naruto and Sasuke to defeat them.

Now, after so many battles, they can no longer say that they can defeat the enemy by relying on the strength of their comrades. Although Naruto still firmly believes that the power of the group can overcome everything, he can also recognize reality.

To fight against the Otsutsuki Clan, one must possess power similar to theirs.

For example, there's Naruto with the Kurama, Sasuke with the Rinnegan, and Boruto awakened the Jōgan due to Urashiki Otsutsuki's power. However, Boruto can only provide assistance at crucial moments in battle, and the actual effect depends on the timing.

That is why Naruto is willing to believe Issei (Shiraha). They need to unite all the forces they can to fight against the Otsutsuki Clan.

"Is this the strength of the Otsutsuki Clan? It feels quite different from Six Paths Madara. In other words, the strongest one right now is Kaguya." After watching the detailed footage of the final battle in Naruto's memory, Issei (Shiraha) was quite surprised. Six Paths Madara's combat power was indeed extremely exaggerated.

Sure enough, the strength gained step by step through self-improvement is much stronger than starting at the maximum level.

However, although those Otsutsuki Clan Member were very poor in actual combat, their innate abilities were extremely abnormal.

In terms of spatial abilities, Kaguya Otsutsuki is undoubtedly the strongest. If she had more practical experience with this ability, Naruto and Sasuke would have been defeated without a doubt.

Even if it were Issei (Shiraha) using this ability instead of Momoshiki Otsutsuki and Urashiki Otsutsuki, he probably wouldn't have been defeated even if Sasuke hadn't lost his Six Paths Yang Power and Six Paths Yin Power.

The abilities of the Otsutsuki Clan, like Shiraha's Innate Spell, can be acquired without learning.

However, Shiraha Yu at least advanced step by step through cultivation. After leveling up, he will continue to familiarize himself with the abilities of his Innate Spell and the possible tactics and battle strategies.

Once the Otsutsuki Clan plants the Divine Tree and swallows its ripe fruit, they essentially ascend to the highest level in one step. This is equivalent to a newly initiated Third Level Wizard (sorcerer) skipping the three stages of materializing Mental Power — Gaseous State, Liquid State, and Crystalline State —and directly advancing to Fourth-Level Star-level Wizard (sorcerer). Such an outcome would inevitably result in advancing to the weakest Fourth-Level, perhaps even unable to use the "Star Domain."

However, judging from the information revealed by Urashiki Otsutsuki in Naruto's memories, as long as one keeps consuming Chakra Fruit, one can increase their strength directly without training and become almost immortal.

In terms of lifespan alone, the Wizarding World seems to be far inferior to the Chakra Civilization of the Otsutsuki Clan.

After all, even Star-level Wizard only has a lifespan of about a thousand years. Even if they undergo various modifications, Plane Exploration, and obtain secret treasures to strengthen their body and soul, their maximum lifespan will never exceed ten thousand years unless they advance to the Fifth-Level. In the later stages, whether they can guarantee the purity of their soul is probably an unknown.

As for Star-Level warlocks, their lifespan depends on the strength of their bloodline origin.

Sorcerers like Shiraha, who have a lifespan of over a thousand years at level one, are extremely rare.

Whether his lifespan will exceed ten thousand years after he advances to the Fourth-Level is still unknown.

What we know so far is that if we can obtain cells from the Otsutsuki Clan, or a large amount of their body tissue for experiments, and if we can capture a live Otsutsuki and put him on the operating table, Shiraha's chances of advancing to Fourth-Level will greatly increase, and the speed of advancement will also be greatly improved.

The key is the longevity of the Chakra system, which allows those he values to also live a long life with him.

As long as they keep consuming Chakra Fruit, Kushina and the others could even live longer than Shiraha.

It's not that the Chakra system is ineffective in combat, but rather that these Otsutsuki Clan Member lack practical experience and skills.

However, this is not hard to understand, because if you always have overwhelming strength and encounter people who are much weaker than yourself, over time, it will really make people feel that they are invincible.

If Shiraha hadn't obtained the "Book of the Ancient Warlock," he wouldn't have believed that a powerful Wizarding World could be defeated by an even stronger Ancient Sound Civilization.

The Ancient Sound Civilization even elevated the path of Bloodline Warlock within the Wizarding World to a completely new level.

"Now it seems that the history of the Chakra Civilization is probably not just a thousand years. It can only be said that the history of the ninja world is too short."

"If Kaguya Otsutsuki Six Paths Madara the combat experience of Madara Uchiha, I wonder if she could First Shinobi World War against a true Star-Level powerhouse."

"As long as I keep increasing my Chakra, there might be a moment of qualitative change. If my energy level is equivalent to level Fourth-Level and I can't beat Star-Level opponent, then if my energy level is equivalent to Fifth-Level, I should be able to defeat Star-Level opponent, right?"

Thinking about it this way, Issei (Shiraha) felt that the Otsutsuki Clan was probably not weak, it was just that the Otsutsuki that had appeared so far were a bit weak.

To be able to physically traverse the universe and colonize planets to plant trees, one really needs considerable strength.

At this moment, Sasuke finished exchanging punches with Issei (Shiraha) and couldn't help but say, "Even though Kushina and Shiraha are both very strong, it will still take a long time for them to reach the level where they can help us deal with the Otsutsuki Clan. I'm afraid we can't afford to wait that long."

Based on the battle scenes they remembered, Kushina and Shiraha were still weaker than them. Although they were second only to the two of them, the enemies they faced were too strong.

Furthermore, with the Land of Whirlpools now being rebuilt, it's impossible for Shiraha and Kushina to both come to their world to stay for an extended period and help them deal with the Kara and the potential emergence of the Otsutsuki Clan.

"To deal with the enemies of your world, you two will naturally be the main force. Sometimes, even without our help in the battle, we can still help you," said Issei (Shiraha).

"So what do you mean by cooperation?" Sasuke frowned slightly. He wasn't as easy to talk to as Naruto; he needed to clarify many things first.

Issei (Shiraha) looked at Naruto and Sasuke with a determined expression and said, "I only have one question: between you two now and yourselves back in the Valley of the End, who is stronger?"

Sasuke's expression shifted slightly, and he fell silent.

Naruto, however, said very seriously, "Sasuke and I haven't relaxed our training too much over the years. Our combat skills and teamwork are stronger than before, but because we lost the Six Paths Six Paths -Yang Power of our great-grandfather, our current strength should be weaker than it was during the Valley of the End."

"So, you've cultivated for over a decade, during your prime years when you're at your peak in every aspect, yet your strength is still not as good as when you were teenagers? What have you been doing for the past decade?" Issei (Shiraha) didn't mince words and pointed out the real problem incisively.

"You mean we need to increase our current strength to the level of the Valley of the End in order to deal with the Otsutsuki Clan? Do you think that at our level, a significant increase in strength can be achieved with just a few words?! Gathering intelligence and investigating the Otsutsuki Clan's whereabouts both require a lot of time and effort."

Seeing Issei (Shiraha) angrily confront Naruto, Sasuke retorted with a somewhat displeased expression.

"Sasuke, don't get agitated. Issei (Shiraha) is right. After becoming Hokage, there are always endless official duties in the village, and I have indeed relaxed a lot in my training," Naruto advised. Now, facing the Kara and the unknown Otsutsuki, strength cannot be improved in a short time.

"If you encounter powerful Otsutsuki Clan Member like Kaguya and Six Paths Madara again, you will have no choice but to confront them with overwhelming force."

Issei (Shiraha) looked at Sasuke and questioned him:

"There's something I don't understand. From your memories, it's clear that Shin Uchiha possesses a special constitution that ignores cellular rejection."

He conducted his own research and even mastered Cloning Technology, and could replicate the Mangekyō Sharingan on a large scale. Why didn't you think of using him to conduct Cell Experiment on the Otsutsuki Clan?

After defeating the Otsutsuki Clan, you didn't even bother to collect their body tissues and cells for experiments! What a fantastic opportunity to become stronger!

Naruto explained, "Human experiments may face many problems. Currently, all parties in the Shinobi World are quite restrained. Only Orochimaru has been conducting research in this area, but even he is subject to strict restrictions."

Issei (Shiraha) was speechless for a moment and retorted, "You need to understand one thing: in a sense, you are no longer human. There is no need for you to be so resistant to Cell Experiment."

Moreover, your conflict with the Otsutsuki Clan is a life-or-death war between races and civilizations. The closer you are to the Otsutsuki Clan at the cellular level, the greater your chances of defeating them.

If the Otsutsuki wins, everyone in the entire Shinobi World will likely become nourishment for the Divine Tree.

As he spoke, Issei (Shiraha) looked at Sasuke again. "If your arm were cultured with cells from the Otsutsuki Clan and then transplanted and fused, your strength would definitely be significantly enhanced. If your other eye also evolved into the Rinnegan, wouldn't that increase your chances of defeating the Otsutsuki Clan?"

"This..." Naruto wanted to explain for Sasuke, explaining that he hadn't accepted the arm transplant back then to 'atone for his sins,' and that even after all these years, Sasuke still refused.

To be honest, Issei (Shiraha) felt somewhat helpless. Even though it was a world of extraordinary beings, if one's mindset could not be liberated, it would still greatly limit the development of civilization and the improvement of personal strength.

It seems that not only this world, but also the world in which the original body resides, needs a complete liberation of thought.

Human experimentation and Cloning Technology may cause many problems, but what are they compared to the extinction of all humanity?

Especially considering they had Shin Uchiha as an excellent human subject for experimentation, they actually killed him without even collecting his body tissue.

Furthermore, the fact that Orochimaru, this scientific research expert, was conducting his research under the close surveillance of Konoha and subject to various restrictions, yet still managed to produce results, can only mean that Orochimaru is truly exceptional.

"We have collected a small amount of the Otsutsuki Clan's body tissues, which are all sealed in the village's ANBU Headquarters," Naruto explained.

Small amount?

Issei (Shiraha) heard this word, his heart bled. What a waste of talent.

If the original body were here, it would probably be cursing loudly.

"Shiraha is an expert in Medical Ninjutsu and clinical trials. As long as you have the body tissue of the Otsutsuki Clan, with his training, your strength will definitely be greatly improved," said Issei (Shiraha). "In addition, have you summoned the Tailed Beast?"

"Why are we summoning the Tailed Beast?" Naruto asked, puzzled.

"Even without the Demonic Statue of the Outer Path, if most of the Chakra of the Nine Great Tailed Beasts were concentrated in your body, making you Pseudo Ten-Tails Jinchuriki, wouldn't your strength surpass that of the Valley of the End period?"

Issei (Shiraha) said.

Naruto frowned. "I already possess the Chakra of Nine Great Tailed Beasts within me, and I've promised to free all the Tailed Beast. If I do that, how am I any different from the Otsutsuki Clan?"

Issei (Shiraha) shook his head. "Of course there is a difference. That little bit of Chakra will have a negligible impact on your strength. What use is it?! And why didn't you think of consulting the Tailed Beast?"

Once you and Sasuke are defeated and your world falls, all these Tailed Beast will be turned into Chakra Pill pills and consumed by the Otsutsuki Clan.

It's just a temporary gathering within your body, giving you greater power to defeat powerful enemies. How do you know the Tailed Beast wouldn't want that?

They might be even more anxious than you are!

"Naruto, what that brat said makes a lot of sense." Just as Naruto was lost in thought, the Kurama inside him spoke up. In fact, it had also thought about this question. The Nine Great Tailed Beasts were originally one. Although they did not want to merge back into one as the Ten-Tails, they only wanted to live their own leisurely lives. But if this world were gone, their good days would naturally end.

Of course, Kurama didn't say anything before because it knew Naruto's personality too well; Naruto would find it hard to agree to such a suggestion.

Furthermore, Kurama) has its own pride; even without the power of the other eight Tailed Beast, it can still help Naruto defeat powerful enemies.

After all, it still has its last trump card— Baryon Mode.

"Naruto, maybe Issei (Shiraha) is right." At this moment, even Sasuke was persuaded, because Issei (Shiraha) seemed even more anxious than them, and this emotion could not be faked.

Sasuke didn't get a new arm for two reasons: one was to atone for his sins, and the other was to keep the eyes his brother Itachi gave him.

Because once the arm cultivated from Hashirama cells is transplanted, the power of the Uchiha and Senju will be completely fused, and his other eye will very likely evolve into the Rinnegan, thus completely changing his brother Itachi's eyes.

"Improving my strength isn't urgent for now. Even if you agree, it will still take some time. So I think you should take me to see Kabuto and Orochimaru first?"

Seeing that Naruto and Sasuke's attitude had softened, Issei (Shiraha) seized the opportunity, since the Otsutsuki Clan's body parts were still sealed at the ANBU Headquarters and wouldn't run away on their own.

Compared to Naruto and Sasuke, who are unaware of their own wealth, he was more interested in seeing what new technologies Kabuto and Orochimaru had developed over the years.

At the very least, the Cloning Technology should be brought back, and the offspring cloned by Shin Uchiha using his own cells should also have the ability to ignore rejection.

He is now eager to see Kabuto and Orochimaru in this world.
