There are five major countries in the ninja world, several small countries, and the country of fire is the most powerful, even if the other big countries don't want to admit it.

However, as time goes by, the Fire Nation seems to be weakening, and now, it feels like it is being caught up by several other powers.

It's not that it's out of purpose, it's that the top power in the Fire Nation is quietly disappearing.

No one knows why, no one delves into it, and it seems that everything can be attributed to the cruelty of war.

However, let's take a look at the history of the Fire Nation.

Senju Tsuruma, the patriarch of the Thousand Hands Clan, shook hands with Madara Uchiha, the patriarch of the Uchiha Clan, and established the Land of Fire.

How powerful the Fire Nation was at this time, if it weren't for the fact that people were tired of war and longed for peace, it would not be impossible for the Fire Nation to sweep through other realms with the power of one country, even if the entire territory of the Ninja Realm was included in the national territory.

After all, both the Senju clan and the Uchiha clan are direct descendants of that immortal.

However, after all these years, how weakened has the Fire Nation become?

If any of the other four great powers stood up and engaged in a reckless war with the Fire Nation, even if the Fire Nation would win, it would have to suffer heavy losses, and it would even be devoured by the Yellow Sparrow behind.

Why did the Fire Nation decline to such a point?

Madara Uchiha's rebellion is one reason, but it does not affect the overall situation of the Fire Country, and the main reason is the fall of high-end combat power and the lack of successors.

From the first Hokage to the current five generations of Hokage, it has only been a few hundred years, and there are only a few remnants of the once glorious Thousand Hands Clan and the Uchiha Clan.

Needless to say, the demise of the Uchiha clan is not to be said, but what about the Senju clan?

The Senju clan, as the largest clan in Konoha, how come it is that only Tsunade is left now?

The Thousand Hands Clan is already powerful, and both in terms of vitality and ninjutsu, they are far ahead. Therefore, it is not too much for a thousand-handed clan to be able to fight ten ninjas of other ordinary races, but now, as the most powerful clan, why is there only one clansman left until now?

The Uchiha clan has a "villain", and there is no Uchiha clan in Konoha Village anymore. Each of the remaining few is very strong, but it is more than a little bit worse than Madara Uchiha.

And in Konoha Village, there is also a powerful ethnic group, the descendants of the Great Barrel Kiba Village, the younger brother of the Six Dao Immortals, the Hyuga clan.

The Hyuga clan said that they were the strongest clan in Konoha Village, and now in Konoha Village, they are indeed the strongest, but they are only the strongest as a group as a whole, and the real high-end combat power, it seems that there is no successor in the Hyuga clan.

But what has happened in a few hundred years?

Judging from the situation in the country of fire alone, it seems that there is no reason, but if you look at it from the level of the entire ninja world, it seems that some clues can be captured.

The big barrel of wood Kaguya came to this world from outside the sky, swallowed the fruit of the sacred tree, and achieved inhuman.

Her two children were born with a gift and a power that the indigenous people did not have, and that was the chakra.

After the two brothers of the Six Paths Immortals sealed their mother Kaguya, the Six Paths Immortals separated from the Nine-Tails, traveled the world, and passed on the power of Chakra to ordinary people one after another, hoping to use this power to bring peace, and thus the ninja was born.

The Six Dao Immortals' approach was right, but because of the power of Chakra, the world that was originally only ordinary people was divided into two worlds.

One is the world of ninjas, and the other is the world of ordinary people.

The rise of ninjas meant that ordinary people were weaker, and the already unstable world did not seem to be moving towards peace as the Six Dao Immortals had hoped.

Time flies, and the Six Paths Immortals have long since become a legend, and even the Thousand Hands Pillar and Uchiha Madara have also become legends.

And how many of those powerful ninjas are left so far? Especially the descendants of the Six Dao Immortals.

From the perspective of the entire ninja world, the direct descendants of the six immortals include the Thousand Hands Clan, the Uchiha Clan, and the Uzumaki Clan.

The Uzumaki clan lives on an island east of the Fire Country, established the Vortex Country, has been friendly with the Senju Clan for generations, and has a powerful sealing technique and vitality.

But now, the country of the vortex has been destroyed, and there are not many people left, only a few mixed-race children left, scattered throughout the ninja world. Of course, Naruto Uzumaki has currently pulled Karu and Nagato into Konoha's camp.

Why did the Vortex Nation perish, Konoha befriended it, and the geographical location of the Vortex Country was so close to the Fire Country, and besides, the Vortex people, as the descendants of the Six Dao Immortals, were not weak, so why would they perish?

No one can give an answer.

The bloodline of the strongest person of the Six Dao Immortals has divided into several powerful ninja clans, but to this day, there are only a few people left.

Although the bloodline of the six immortals' younger brothers, Yucun, has not declined to such a point, for the huge ninja world, their role has become minimal, and they are no longer as glorious as they once were, and they can't make any waves.

Not only these few powerful bloodlines, but also many powerful ninja clans that were famous for a while, also disappeared with time one by one.

The Kaguya clan, that is, the clan of Jun Maro, has completely disappeared, and Bai, who has mastered the Ice Escape Ninjutsu, is also the only one left in his clan, and there are many, many other clans that have completely disappeared one by one.

The ninja world seems to be getting more and more prosperous, but in fact it is getting weaker and weaker, and no one can say why.

The decline of the Fire Nation also symbolizes the decline of the ninja world, if this world does not have the appearance of Naruto and others, where will it go?

Perhaps, in the decline of destruction, perhaps, in the decline of the ninja there is no more ninja.

……

The Island of Exile, that is, the former country of the vortex and the land of the Vortex Clan.

Since the destruction of the Vortex Country, ninjas from various countries and ethnic groups have been sent here to defend it.

However, due to the large number of people and the continuous conflict, these criminals who had invaded the country of Vortex were withdrawn again, and some exiles were injected here.

Exiled ordinary people, exiled ninjas, all uncertain danger factors, make up the composition of people on the island, lawlessness, all evil, is the true portrayal of these people.

At this time, a large hall was hidden in a hidden place on the island.

The main hall is majestic and solemn, with two columns of candles flickering, emitting a small amount of light and heat, extending from the front to the end of the hall.

There were several personnel standing below, respectfully waiting for something.

Suddenly, the candle flame in front of him went out, and the light suddenly became blurred, and a figure suddenly appeared.

He wasn't tall, shrouded in darkness and couldn't really be seen.

However, as soon as the few people below saw the visitor, they immediately saluted respectfully, and everyone's face showed a bit of fanaticism.

Raising his hand, a letter flew out of the cuff of the figure in front of him and landed in the hand of the man led below.

"My lord, what is this?"

"Make a copy of this letter and send it to the countries." Some hoarse voices commanded.

"Yes!"
