After the Chūnin Rebellion was resolved, the Leaf Village once again entered a period of peace.
Kakashi, as the Hokage, also gained immense fame.
The reason was, of course, quite simple.
During the previous crisis, Kakashi had directly summoned ten Hokage to assist.
Any trouble was swiftly and decisively resolved.
Now, the ninjas of the Leaf Village in this world revered Kakashi to the utmost.
Even in the other major nations, Kakashi's name was like thunder ringing in their ears.
Everyone unanimously agreed that Kakashi's personal strength didn't matter much.
What was most important was his ability to summon ten Hokage for support.
That was the key point.
After all, no matter how powerful an opponent might be, they were still just one person.
If he could directly summon ten Hokage, what could anyone possibly do to fight him?
Simply put, being strong yourself was not as good as having powerful allies.
After the resolution, the other Hokage also prepared to leave.
Obito asked, "Kakashi, what do you plan to do next?"
"Just like in the other worlds, unify the Ninja World?"
Kakashi nodded. "Of course, that's something we must do."
"However, it probably won't progress as quickly as it did for you."
"Right now, the Leaf's strength isn't formidable enough yet."
"I think we should start with the surrounding smaller nations first!"
His plan received unanimous praise from the other Hokage.
Everyone then returned to their original worlds.
Not long after, progress advanced rapidly.
Significant changes occurred in each world.
In the Shira World, after the unification of the Ninja World, everything was peaceful.
With both Madara Uchiha and Black Zetsu dead, no one dared to cause trouble for the Leaf Village.
Coupled with Aoki's strength, which was evident to the entire world, it was so overwhelming that no one dared to entertain any inappropriate thoughts.
This period was very peaceful, with only occasional criminal incidents occurring.
Under the ninjas' crackdown, such incidents were easily resolved.
During this time, the Konoha Twelve Young Warriors were also born one after another.
Naruto, Sasuke, and the others all came into the world.
It seemed a new era was about to unfold.
During this period, what Aoki focused on most was not anything else, but scientific research.
After unifying the Land of Lightning, the Leaf's technological level underwent rapid evolution.
The Land of Lightning's technology was highly advanced.
Coupled with the unification of the Ninja World,
Aoki gathered all the scientific research talents from the major Ninja Villages.
He provided them with abundant resources
and substantial research funding,
ensuring they had no worries,
allowing them to focus wholeheartedly on developing various scientific technologies.
Whether it was Biotechnology
or technology related to Ninjutsu and Chakra,
all received strong support.
With this backing,
the researchers welcomed their own spring.
Various patented technologies emerged rapidly like bamboo shoots after rain.
All kinds of Chakra Weapons were continuously evolving.
Things like Scientific Ninja Tools were also invented.
In the field of Medical Ninjutsu, progress was swift as well.
Medical standards and Biotechnology levels grew more advanced day by day.
The living standards of ninjas also continuously improved.
Various new technologies transformed the Ninja World, making it even better.
Hokage's Office.
Aoki was about to casually browse the Hokage Chat Group.
Kakashi pushed the door open and walked in.
"Hokage-sama, it's the latest scientific research achievement."
He took out a scroll and handed it to Aoki.
Aoki found it strange.
Usually, there was no need to report such things to him.
Why was it suddenly being reported today?
And it was Kakashi himself delivering the report.
As one of the most elite ninjas,
Kakashi's daily routine was extremely busy.
Matters that required him to report personally
were truly rare in this era of peace.
Aoki voiced his doubts.
Kakashi explained, "This invention is very unusual."
"You gave instructions when the project was first established."
"Any progress must be reported to you immediately without fail."
Upon hearing Kakashi's words,
Aoki immediately understood.
He knew what the message in the scroll was about.
He opened it, and sure enough, it was as he thought.
The scroll contained the latest Chakra Cannon invented by the Lightning Division Scientists.
This Chakra Cannon had already achieved an incredibly exaggerated level of power.
A single shot could pulverize a Meteor into dust.
If this Chakra Cannon were placed in the original timeline,
it would have taken at least over a decade to develop,
and only the Land of Lightning could have accomplished it.
However, under Aoki's leadership,
it was completed so early.
Aoki briefly reviewed the demonstration level.
It was basically similar to the Chakra Cannon level he had seen in Sixth Hokage Kakashi's world.
It must be said, it was already a very high standard.
Aoki was very satisfied with this.
"Excellent!"
He said to Kakashi,
"The research staff who developed this product will receive double their annual bonus this year!"
Kakashi noted down his words.
"Next, this Chakra Cannon still has room for further development."
Aoki said seriously, "It would be best to miniaturize this thing."
"So that ninjas can carry it with them."
"This would greatly enhance everyone's combat power."
Upon hearing Aoki's words, Kakashi nodded repeatedly.
He recorded all of Aoki's ideas
for other scientists to continue developing in the future.
Hashirama Senju, the First Hokage's world.
Last time, Hashirama, relying on his exaggerated strength, easily conquered the Land of Earth. Originally in no hurry, he continued his advance. However, chaos erupted within the Land of Lightning. Many of its high-ranking officials believed that Hashirama's power was simply too overwhelming. Rather than resisting and engaging in a war destined for defeat, it would be better to surrender. This way, at least the younger generation of the Land of Lightning would have a chance to survive.
Led by the Raikage, the Iron-Blood faction absolutely disagreed with such thinking. The Raikage's stance was to fight to the death. Even if Kumogakure were reduced to its last person, they would never surrender to Hashirama.
The internal turmoil in the Land of Lightning also reached the ears of those in the Leaf. Upon learning of this situation, Tobirama immediately recognized it as a once-in-a-lifetime opportunity. He promptly advised Hashirama that if they could defeat the Raikage now, they could seize the entire Land of Lightning in one fell swoop.
Without hesitation, Hashirama set out with a large force of ninjas. He defeated the Raikage and a portion of his subordinates within the Land of Lightning. The remaining forces decisively surrendered. Just like that, the Land of Lightning fell into Hashirama's hands!
Thus, all of the former Five Great Nations of the Ninja World had now come under the rule of Konohagakure. All that remained were those minor nations in remote regions, such as the Land of Snow. Complete unification was not far off.
