First, the most important point is "coordinate exposure."
As long as aliens from the Otsutsuki clan still exist in this world, they will inevitably, at some point in the future, arrive in the ninja world and continue the unfinished work of Kaguya and her servants, destroying the world.
There wasn't much Ryosuke could do about this.
He couldn't control whether others would come or when they would come. All Ryosuke could do was make himself and the companions around him stronger.
The second key point was the "pure white and flawless" super soldiers.
This…
Ryosuke and Kamihara Hayato exchanged a look, and from each other's eyes, they saw the same answer,
White Zetsu.
Ryosuke recalled Black Zetsu's death message.
"Black Zetsu is Kaguya's son."
"White Zetsu are Kaguya's super soldiers."
Suddenly, many things seemed to make sense.
Then what about Uchiha Obito, who had been mixed up with Black Zetsu and White Zetsu from the very beginning, what key information did he know?
"There's one more thing."
Kamihara Hayato lightly kicked a few stone slabs placed to the side and said, "This part wasn't in the mural. It was recorded separately. Back then, the Hagoromo and Hamura brothers probably didn't spare her just out of mother–son affection."
Thinking about it, that made sense. Once it had reached the point of an eternal seal, for Kaguya, it was basically no different from death.
"You're saying… the brothers couldn't kill her?"
Kamihara Hayato nodded.
"This is just my speculation..."
"Kaguya, or rather, the Otsutsuki clan, has some extremely powerful regenerative ability, just like Hidan, like you, so only sealing could prevent her from reviving again."
"Following this line of thought…"
"The servants mentioned in the mural, could they also still be alive?"
A pure-blood Otsutsuki who had lived for a thousand years, hiding in the shadows.
Ryosuke smiled. "That sounds like a ghost story. If that servant were still alive, why would there have been no movement at all for a thousand years? After all, Kaguya is dead, he would be the strongest person in the world."
Using Toneri as a benchmark, Ryosuke didn't think there were many people in the history of the ninja world who could stand up to a pure-blood Otsutsuki.
"Who knows… it's just my speculation."
Kamihara Hayato was simply acting on the habits of an intelligence officer, listing all possibilities one by one, then eliminating and filtering them to arrive at potential intelligence.
Ryosuke shook his head, stopped thinking about the "servant" issue, patted Kamihara Hayato on the shoulder, and said, "You guys keep digging."
"And you?"
"I need to ask about the progress of exploring the 'future.'"
An hour later, Ryosuke entered the Great Toad Palace. The moment he stepped inside, he smelled a rich tea fragrance. Seeing him come in, the Great Toad Sage, who was pouring tea, had his hand tremble slightly. Smacking his lips, he asked, "Hey, Ryosuke, I know you young people are energetic and physically tough, but…"
"Don't you need to rest at all?"
Ryosuke smiled. During the gap when he had checked his system gains, he had already rested, and even had a cup of tea along the way. He didn't answer the question directly and got straight to the point, "Does Absolute Darkness… still exist?"
The Great Toad Sage raised the teacup in his hand and revealed a helpless, regretful smile.
Absolute Darkness was still like an insurmountable cliff, blocking all glimpses of the future.
With Hidan's reminder, Toneri had a sudden inspiration and created a tattered version of Absolute Darkness. But in the end, he was just a clumsy imitator, and the world did not fall into eternal night.
First Uchiha Itachi's spacetime black box, then Toneri's lunar light-blocking curtain, two consecutive wrong judgments. Ryosuke felt tired and gently shook his head.
Whatever.
Absolute Darkness, coordinate leakage, aliens that could attack at any moment.
The preparation Ryosuke needed to make was always the same, just keep getting stronger.
Speaking of getting stronger…
"Can I practice senjutsu?"
Ryosuke asked the Great Toad Sage.
In the fierce battle with Toneri, Ryosuke had personally felt the terrifying amplification that the senjutsu chakra of the three sages gave to one's body. If he could make that power constant, it would definitely be a significant boost for him.
The Great Toad Sage scratched his head and asked, "Do you mean 'senjutsu,' or 'senjutsu chakra'? If it's the former, you're already an expert. If it's the latter… well, how should I put it, the heavens are fair. Just look at you…"
"Alright, alright."
Ryosuke raised his hand, signaling the Great Toad Sage not to continue.
Not long after arriving in this world, Ryosuke had already known that he lacked chakra talent. Back then, he had even learned the Great Fireball Technique with Sasuke. Four years ago, it was the size of a palm. Four years later, it was still the size of a palm.
There had been no progress at all.
The Great Toad Sage saw through Ryosuke's thoughts,
"Don't worry. If enemies like Toneri appear again… even though I'm old, I can still spare part of my senjutsu chakra. The Slug Sage will naturally do the same."
"The only thing to worry about is the White Snake Sage."
At present, White Snake Sage No. 18 was still in a coma. Its life fluctuations were unstable, and no method to wake it up had yet been found.
The Great Toad Sage sighed. "If one day it wakes up, how do you plan to deal with it?"
Mount Myoboku and Ryuchi Cave, those two forces weren't exactly friends.
Many times, the toads below and the snakes looked down on each other. But from the span of history, countless outstanding figures had already turned to ashes of the past. Those who were still alive, even if they didn't see eye to eye, would still leave a little space for the other in their hearts.
Ryosuke answered very decisively, "Investigate whether it committed any major wrongdoing after its birth, then have experts evaluate the sacrifices it made this time and the contributions it brought."
"Balance merit and fault, and see what's left in the end… most likely, the merit will outweigh the fault. After all, without its help, many people might have died."
"Just that simple?" the Great Toad Sage asked.
"Just that simple."
Regarding the clones born after the death of the White Snake Sage, Ryosuke had thought it through very clearly, they were merely a group of newborns who had been copied with memories and possessed extremely high danger and aggressiveness.
They were not the White Snake Sage.
They were just forcibly implanted with memories that did not belong to them.
For example, if one day Ryosuke died, and a child read all of Ryosuke's memories through a memory disc, and was then given a command by the Gate of Heaven, "Forget your own life. Treat Ryosuke's memories as your own."
Could that child be called "Ryosuke"?
How others would think, Ryosuke didn't know. But at least in his view, the answer was no.
So, in his eyes, whether it was Evil God White Snake No. 1 or No. 18 who had come to assist this time, neither counted as the White Snake Sage, and naturally neither should bear the sins of the White Snake Sage's past.
If encountered, considering their danger, Ryosuke would definitely imprison them immediately, after all, deep down, they wanted to kill him.
But No. 18 was different.
It had truly helped Ryosuke and saved this world. Ryosuke couldn't accept benefits from someone one moment and then turn around and burn the bridge the next.
As for the hidden risks this might bring…
Ryosuke felt that when everyone in the world knew that No. 18 had come to help, and had even exhausted its power and fallen into a coma with its life and death unknown, not doing this would be the real hidden danger.
One more enemy doesn't matter.
Once people's hearts scatter, they won't come back together.
The Great Toad Sage nodded slightly, understanding Ryosuke's meaning. Seeing him stand up, ready to leave, he asked, "Perhaps this is the best ending. What do you plan to do next?"
Ryosuke turned back and said, "The alien problem is resolved. It's time to carry out a 'test' that's been delayed for quite a while."
"What test?"
"The name is a bit long."
Ryosuke recalled it for a moment and said, "'Testing the Effects on Obito of a Tailed Beast Bomb Infused with Ripple, Drawn into the Kamui Space Along a Golden Rotation Trajectory.'"
