Makoto's plan remained unchanged.
The Teleportation Formation was still off-limits.
However, he felt that simply allowing the White Zetsu to monitor the area until Ōtsutsuki Toneri appeared was a flawed strategy.
You cannot defend against a thief every single day, can you?
While deploying a few White Zetsu was not a significant loss for Makoto's side, it was an unsustainable solution.
Therefore, a permanent fix was needed.
Just because Makoto and his group could not travel to the Moon did not mean they could not force Toneri to come down to them.
Makoto notified the Five Great Nations and various smaller countries within the alliance, requesting their "cooperation."
This cooperation was mutually beneficial.
In the early stages of their industrial revolution, the problems were not yet apparent.
But as time passed, pollution and waste from technological advancements would increase.
In the future era, this waste was dumped into the Land of Rain.
On Runeterra, Piltover's waste was dumped into Zaun.
In the real world, Japan's sewage was dumped into the ocean.
These things need somewhere to go.
Makoto saw the desolate Moon as an ideal waste disposal site.
Thus, the nations' shit and sewage reserves were collected by Kakashi, the designated "Shit Collector," and stored inside the Kamui Dimension, ready to be transported and released into Toneri's living room.
Indeed, geopolitical debates over resources had become pointless.
Agriculture now relied on Orochimaru's Shinobi World-specific fertilizer.
No longer requiring lengthy debates over raw materials, the new process simply involved controlling the proportions of ingredients and adding a small amount of Hashirama cells to a large batch of manure to induce explosive crop growth.
Kakashi had volunteered for this sanitation task the moment he learned about the situation.
Originally, under Tsunade's direct orders, Kakashi had replaced Shizune and begun the arduous task of handling all Hokage administrative duties.
And it must be said, Kakashi truly lived up to his reputation as Konoha's top technician, managing peacetime affairs with remarkable ease.
Look at the tenures of Konoha's Hokage throughout history: The First and Second Hokage each served for around eight years.
The Fourth Hokage had the shortest tenure, lasting only one year.
The Fifth Hokage, Tsunade, served for around four years—roughly from the beginning of Shippuden to its conclusion.
Apart from Sarutobi Hiruzen, who occupied the seat for thirty-one years, Kakashi held the longest tenure, serving for around ten years.
As for Naruto, he inherited his father Minato's speedrun trait.
He became the Seventh Hokage, but was imprisoned in another dimension by the time his son Boruto was thirteen.
All told, his actual time doing the job was even shorter than Tsunade's, who had been thrust into the role against her will and had largely given up on the paperwork.
Just over three years.
In short, Kakashi, having lost his Sharingan in the original timeline, no longer had a standout combat skill, but he remained an all-around administrative genius.
Making Kakashi her successor might have been a spur-of-the-moment decision by Tsunade, but she had chosen the right person to inherit her desk.
And Kakashi?
The Kakashi of the past was not the "King of Tardiness" or the "Lazy King."
But to live up to his dead best friend Obito's image, he had relentlessly imitating him.
This cosplay had persisted for over a decade.
It is easy to go from frugality to extravagance, but difficult to return to frugality.
After acting like a slacker for so long, it had naturally become a habit—a reality.
Kakashi desperately wanted to ask Tsunade for a day off.
But after working overtime for three consecutive days, he showed no dark circles under his eyes, no signs of fatigue whatsoever.
How could he possibly explain this to Tsunade? Feigning illness?
As a master medical ninja, Tsunade would see through his charade in an instant.
So Kakashi worked through two more sleepless nights.
He could not tell if his body was exhausted, but his mind was on the verge of collapse!
Whenever he felt he was reaching his limit, a mysterious force would surge through his veins, restoring his energy.
This sensation was suspicious.
It felt similar to how he had recovered after overusing Kamui and being hospitalized.
'Could it be...?'
Kakashi recalled his recent traumatic experience, daring not to dwell on the cursed implications of what the masked man had force-fed him in that hospital bed.
Fortunately, Makoto's message arrived at that exact moment.
Kakashi volunteered his services, arguing that using standard sealing scrolls for global sewage would be too cumbersome and wasteful.
He proposed using his ocular jutsu instead.
Upon learning of Kakashi's offer, Makoto thoughtfully dispatched Uchiha Hikari and Nohara Rin to assist him.
Hikari merely left an Eight Thousand Spears mark on Kakashi.
Rin, however, accompanied Kakashi on his travels to various countries, collecting old color televisions, broken refrigerators, and millions of gallons of raw sewage, storing them all in the Kamui Dimension.
The effectiveness of Kamui is directly linked to Chakra reserves.
During the Fourth Great Ninja War, with the Nine-Tails' Chakra cloak, Kakashi had been able to transfer the massive Eight-Tails directly into the Kamui Dimension, catching it off guard.
Therefore, Rin's role was to act as a battery, lending Kakashi Tailed Beast Chakra to maximize his use of Kamui.
Since Kakashi already possessed Hashirama cells, frequent use of Kamui would not degrade his vision.
The only thing he lacked was Chakra itself.
For Nohara Rin, this endeavor served as valuable training.
To utilize the Three-Tails' Baryon Mode, she first needed to establish a harmonious partnership with the beast.
Stabilizing and gently transferring Tailed Beast Chakra to another person was a practical form of medical training.
Furthermore, the ever-helpful Senju Tobirama assisted them by using the Flying Thunder God Technique to teleport them between countries, saving them precious travel time.
Tobirama certainly was not helping just to irritate that Uchiha masked man.
Over the past few days, the masked man's initial rage had devolved into trembling fear.
He secretly returned to Konoha once but failed to find Kakashi.
He had no idea where his former teammate was or what he was doing.
All he knew was that Kakashi had weaponized half of his Dōjutsu.
He could no longer use Intangibility or transport himself to the Kamui Dimension for a quick nap!
Now, whenever he activated his Intangibility, that specific part of his body would phase into the dimension and be exposed to a swirling ocean of liquid shit!
Each time he used Intangibility to dodge an attack in the real world, another portion of his body would be dunked in toxic waste.
It was better not to dodge at all.
The masked man began to deeply regret his life choices.
He should never have injected Kakashi with Hashirama cells.
Now, with no physical restraints or stamina limits, Kakashi had become a shit absorbing monster!
Even Konoha's entire plumbing system could not have filled his Kamui Dimension to such an extent!
"Has Kakashi transferred all the Shinobi World's shit into the Kamui Dimension?!"
The masked man felt despair creeping in.
The last time Kakashi had transferred the explosion of Konoha's septic tanks, it had taken him ages to mop the geometric blocks clean.
This time, he feared no amount of scrubbing would suffice!
How would he ever enjoy eating curry rice or soaking in his private hot springs inside the Kamui Dimension again?
"Kakashi you bastard! No wonder your Summoning Beasts are dogs—you must love rolling in shit! I should have gouged out your eyes..." The masked man gritted his teeth in unspeakable fury.
...
"Mission accomplished."
Kakashi was teleported by Tobirama's Flying Thunder God to the hot spring entrance of the Moon's Teleportation Formation.
Throughout the journey, Uchiha Hikari's Eight Thousand Spears remained unused.
Nohara Rin had supported Kakashi the entire time, channeling the Three-Tails' chakra.
Yet Kakashi could not bring himself to be happy.
He had volunteered for this sanitation mission seeking relaxation and a vacation from Tsunade's paperwork.
And what was the purpose of a vacation? To read his porn, of course.
But with Nohara Rin standing right by his side, if he pulled out a smut novel, she would inevitably lean in to see what he was reading.
And then...
If his childhood crush discovered what kind of degenerate books he was reading in his free time, how could he ever face her again?
