This rabbit was originally a chakra construct Lin Nan pulled from Kaguya.
Kaguya, after transforming into the Ten-Tails, also became a rabbit-shaped monster, so it wasn't strange for the Ten-Tails' chakra to take on a rabbit form.
Perhaps this rabbit wasn't merely a simple Ten-Tails chakra construct, but might have also contained consciousness from Kaguya.
After all, when Lin Nan first pulled the rabbit out, it was incredibly fierce. Lin Nan eventually had to use the Infinite Tsukuyomi to subdue it.
If it were just the Ten-Tails' chakra, it might not have served Lin Nan's purpose.
That's right, Lin Nan wanted this rabbit to extract Ōtsutsuki genes.
What kind of world was the future?
It was the world of Boruto, where Boruto was Naruto's son, and by then, Naruto had been weakened beyond measure.
In that era, the main villains were essentially Ōtsutsuki.
From Ōtsutsuki Momoshiki at the beginning to Ōtsutsuki Isshiki later, each was more formidable than the last.
Lin Nan thought carefully. Even if one cultivated ordinary chakra to the height of Naruto and Sasuke, with a Senju body and Sharingan, they wouldn't be a match for the Ōtsutsuki.
Therefore, Lin Nan believed his current strength might not be equal to the Ōtsutsuki, ultimately because of the Ōtsutsuki's peculiar physique.
The highest level of the so-called Senju body was only the level of Hagoromo Otsutsuki.
But Hagoromo Otsutsuki was merely a half-blood of Kaguya Otsutsuki and a human, far inferior to the Ōtsutsuki physique.
Thus, Lin Nan intended to utilize Orochimaru and Kabuto's genetic research to clone an Ōtsutsuki body.
If successful, this would be the final step in Lin Nan's three-step plan.
The so-called three steps for peace: the first step was to offer his own life, using Samsara of Heavenly Life to revive those who could be revived, such as Sasuke and Guy.
Then came Orochimaru and Kabuto's research into Ōtsutsuki genes.
If the research progressed quickly enough, one step might even be forgone, but if it were slow, that step would be necessary.
It would be ideal if an Ōtsutsuki clone could be replicated within three years, allowing for a seamless transition.
However, ideals are often beautiful, while reality can be harsh.
It would be a significant achievement to even produce an Ōtsutsuki clone before Momoshiki's arrival on Earth, as this was a monumental undertaking.
Furthermore, if he were to die after performing Samsara of Heavenly Life, who would be willing to revive him? That was a question.
This was why Lin Nan currently trusted no one. Let alone Orochimaru, even Kabuto was more trustworthy than him.
Kabuto was now in a state of "seeing through the world's vanity," where peace was his sole aspiration.
And in Lin Nan's endeavors, Kabuto could be considered the most devout follower, at least on the surface.
Lin Nan wasn't overly worried.
Once the legal documents were in place, and three years of peace permeated the world, everyone would understand the true meaning of peace.
Originally, Lin Nan had planned to bring out Kaguya's rabbit after performing Samsara of Heavenly Life.
For Orochimaru, the mad scientist, this rabbit held immense value, and Lin Nan could use it as leverage to coerce him.
But after some thought, Lin Nan changed his mind.
Wasting three years was unnecessary.
With those three years, the Ōtsutsuki clone might already be manufactured.
Time ticked by, and Orochimaru and Kabuto's experiments proceeded apace.
Meanwhile, the smaller nations, under the joint pressure of the five great nations, had either willingly or unwillingly joined the United Nations.
And after precisely three months, the first version of the "United Nations Constitution" was finally unveiled.
Lin Nan immediately disseminated this law throughout the entire ninja world.
The "Constitution" was merely the most basic legal restraint; criminal and civil laws would follow.
Criminal law, as the name implied, would address all lucrative avenues, thereby further tightening the reins on the populace, ninjas, and nobles.
And the so-called "civil law" was intended to abolish the class system.
In the ninja world, although not apparent on the surface, the clan system was still deeply entrenched.
Take Neji as a simple example.
The Hyuga clan had a main family and a branch family. Branch family members were born with the "Caged Bird" seal, signifying a lifetime of service to the main family.
Even Naruto, who vocally advocated for justice for Neji, saw Neji remain a "Caged Bird" until his death in the original story.
This situation did not improve even after Naruto became Hokage.
It wasn't that the Hyuga clan no longer had Caged Birds, as the branch family members of the Hyuga clan had all perished after the Fourth Great Ninja War, leaving no one for the Caged Bird seal. But other clans might not be so fortunate, and other nations were rife with such practices.
The Uchiha clan was suppressed by Konoha due to their Sharingan, and the Uzumaki clan of the Land of Eddies was annihilated by a coalition of other nations due to their naturally potent chakra reserves.
Such tragedies were abundant.
Neji, although alive due to Lin Nan's butterfly effect, was still fated for such a life. Lin Nan did not mind changing his destiny in place of Naruto.
What Lin Nan intended to do was abolish the clan system.
Clans could exist, but not independent "clans."
Here, "clan" referred more to nobility, as most daimyo of various nations hailed from noble families.
Lin Nan aimed to abolish the class system, making nobles no different from commoners.
Of course, he was merely providing the idea; the specifics would require the ingenuity of the councilors.
As long as they could establish laws that met Lin Nan's standards, Lin Nan would endorse them.
The construction of a superpower and a world of eternal peace might initially require the use of force, but later, force alone would not suffice; it would require winning the hearts and minds of the people.
After all, if the populace lived in peace and contentment, and was happy and healthy, who would desire to wage war?
Everyone understood this principle, but its execution was incredibly difficult.
However, up to this point, all processes were on track, and the results were surprisingly good, even exceeding Lin Nan's expectations.
The contributions of the Five Kage were undeniably immense.
Firstly, the Five Kage were generally held in high regard by the populace. Their endorsement of the United Nations and the proposal of laws, coupled with the daimyo's approval, quickly propelled this movement throughout the ninja world.
Although the upper echelons of the world seemed to be in constant flux, the common people at the grassroots level experienced little upheaval.
Life continued day by day, with less tribute and taxation, and fewer bandits.
Just as the surface of the ocean might be tumultuous, its depths remained eternally tranquil.
