In the Naruto world, the island that opened up this spatial passage has been fully developed.

At this time, in addition to the huge fortress that protected the spatial passage, several cities were built in the vicinity of the fortress.

Then, there are several port cities on this island, and there are already trains between the cities, and there is this round-trip railway through the space passage, connecting the territory of the moon.

In addition to the city, there is also a large area of farmland, and then there is no war, the wind and rain are smooth, the land is fertile, and there is a farmland cultivated by scientific planting, and it has been a bumper harvest for eight consecutive years.

With such a harvest, the logistics department has already built dozens of large granaries here, hoarding enough food for the entire Sky Pirates to use for a year.

Fertile land was developed, water conservancy equipment was also developed, and then various minerals were identified.

In those areas with large mineral deposits, many arsenals have been established to create weapons of war.

For example, the Detonator Manufacturing Factory, the Shuriken Manufacturing Line, the Kunai Assembly Line, and the Chakra Weapon Forging Factory.

In the Naruto world, a chakra metal unique to the Naruto world was discovered.

This special metal is infused with chakra, giving the weapon the energy of the chakra, which can cause more damage to enemies.

However, this metal vein is not only deeply buried, but also has a high metal hardness, which is difficult to develop.

However, in the One Piece world, there is such energy as metal fruits. After the development of the first piece of metal, this chakra metal is not lacking.

Now, every warrior in the ninja legion is equipped with this chakra metal dagger.

The railroad of this train was not only built on the island, but also laid on the sea, extending to other islands.

In this way, not only has the scope of the Sky Pirates expanded, but it is also very convenient to transport materials.

Over the years, several legions have been cleaning up the beasts of prey on the islands.

These beasts have been piled up in dozens of warehouses as reserve food.

Since then, some of the outposts where the islands are located have been turned into beacons and port cities.

The First Legion, which had been sent out of the outposts, had now been withdrawn, and those stationed had been handed over to the newly formed garrison.

After that, as the first legion with the strongest combat effectiveness, it is now continuing to train and improve its strength.

Eight years of development, now, in addition to the scope of the activities of those ninjas in the Naruto world.

All the desert islands are occupied by the Sky Pirates, but there are still outposts on the islands close to each country.

Until the Sky Pirates have decided to show themselves in front of the Ninja Village, they are still developing in secret.

And in the past eight years, the five people who were sent to the underworld by Wang Chenyin have already established a small country.

Among them, after Perona became an adult, after studying with Nico Robin for six years, she was sent by Nico Robin to the underworld to form an intelligence unit.

Now, the size of that underworld world is not large, only the size of the land within the range of ninjas in the Naruto world.

However, with the merger of the One Piece world, the land of the underworld began to expand, absorbing the aura that the world was transformed into, and then passing through the world wall of the underworld and transforming into various substances.

Now, the land of the underworld has expanded by more than double, and it is now expanding all the time.

And now, absorbing the power of the rules of the underworld and raising his strength to the level of the holy realm, Cross is also the strongest under the god of death in this underworld.

Then, the lich and the zombie, the two of them also reached the peak of the ninth order, and because of the two concepts of zombie and lich, the underworld was introduced.

In addition to the ghosts and ghosts, the underworld was born with the birth of lichs and zombies, and the skeleton clan was also born with the appearance of Brooke.

And the two of them, as the first lich and the first zombie in the underworld, may now break through to the Sanctuary level at any time.

Then, it was the ability of the Yellow Spring Fruit, Brooke, and now, his strength had also reached the peak of the ninth order.

Moreover, to give one more species to the underworld, the three of Brooke were all favored by the underworld, and they received a certain amount of rewards from the underworld.

And Wang Chenyin also took the opportunity to obtain a part of the rules of the underworld, and now, Perona is in the underworld, absorbing the rules of ghosts, and her own strength is constantly improving.

With a certain amount of authority in the underworld in his hands, now Wang Chenyin is like opening a gap in the underworld.

With this part of the authority, Wang Chenyin can continue to expand his will, and finally, he can also control the entire underworld.

Now, with one Sacred Domain, three ninth-order peaks, and a seventh-order peak powerhouse, Cross has won one-fifth of the land in the underworld.

Dozens of cities have been built on this land, and in them, anyone who yearns for peace can live in them.

Moreover, due to the particularity of the underworld, the dead are not tireless at all, and Cross still formed an army of tens of millions, including dead pirates, or dead ninjas.

Half of the rest of the land belongs to the Grim Reaper and the legions controlled by the Grim Reaper, and then, the careerists who have been resurrected from the world, and even the dead powerhouses of the Hundred Beast Pirates and the BIGMOM Pirates have appeared in the underworld.

However, these people died a year or more ago due to the fact that they had already merged into the world.

When his soul was attracted by the world, he didn't have much strength, and his soul was consumed by the world, and now, in the underworld, he was a strong man in a town.

The rest, there are ninjas and pirates, who have built up large and small strengths, but they are not as strong as the Sky Pirates and the Grim Reaper.

Then, in the underworld, Wang Chenyin asked Cross to find the shadows of the various villages that had died in the Naruto world.

Now, the first Hokage and the second Hokage have been found, and they have joined the army of the underworld of the Sky Pirates.

With this strength and this authority, Wang Chenyin also took advantage of the fact that the god of death was not paying attention, and fused this underworld little by little.

Moreover, the control of the entire world, after stabilizing, is also expanding little by little, and continues to extend towards the control of the entire world.

After feeling the beginning of the third ninja world war in the ninja world, Wang Chenyin began to move between the five major countries through the statues of the gods he had arranged before.

Wang Chenyin's figure appeared on every battlefield, and after the battle, he absorbed the souls of the dead ninjas.

From the soul, those combat experiences, as well as the cultivation methods of various numbers and other skills, are extracted.

Then, the soul that had no effect was transformed into pure soul power by Wang Chenyin and stored by Wang Chenyin.

A big war, the famous Battle of Kanna Kunqiao in the history of the ninja world took place, and the Uchiha Obito who died in that battle, the future big boss began to be born.

Moreover, in the third ninja war, there is also a station that became famous, and was called by other ninjas the wave wind water gate of Konoha flash.

Then, Jiraiya, Tsunade, Orochimaru and the Sanshoyu Hanzo, who is known as a demigod, fought in the Land of Rain.

Eventually, Hanzo called him the Three Shinobi, and then, Kakashi's father, Kakashi Hagi, committed suicide.

In the Land of Water, under the leadership of the current four Hokage's Mizu, the cleanup of some rebellious ninja families began.

The various blood succession families of the Water Country have perished one after another, the strength of the Water Country has been greatly reduced, and the blood mist policy in the village has caused the dissatisfaction of many ninjas.

After the Great War, the entire ninja world, after nearly 10,000 ninjas were killed, the Great War ended.

In the end, under the leadership of the three ninjas, the ninjas of Konoha Village defeated the ninjas of other villages and became the winner.

And each country has also lost a large number of ninjas, and has started a new round of recuperation.

And in this big war, Wang Chenyin collected the intelligence of the entire ninja world, and all the ninjutsu was collected.

In this way, the army under Wang Chenyin has a new ninjutsu to learn, and the strength of the five ninja legions has also been raised to a higher level again.

Moreover, the psychic beast clan, in addition to the Miaomu Mountain, the Wet Bone Forest and the Earth Dragon Cave, on a wasteland outside the Naruto world, and on a snow-capped mountain, Wang Chenyin found three new psychic beast races in the sea.

These two psychic beast races are the ferret clan on the Great Snow Mountain and the white bone scorpion clan in the rocky wasteland.

As well as the Abyss Octopus Clan of the Shadow Sea, these three races, and the Toad Clan of Miaomu Mountain, the Wet Bone Forest of the Immortal Clam, and the Snake Clan of the Earth Dragon Cave.

They all have their own immortals, as well as their own inheritances, and the size of the three races is also very large, and there are many strong people in the clan because there are no enemies.

However, after being discovered, Wang Chenyin used the combat power of his holy domain to directly go to the door and bring the three psychic beasts into the Sky Pirates.

Then, in the ninja army, you can contract the psychic beasts of the three clans.

Moreover, you can also go to the three clans to learn the immortal patterns that exist among the three clans.

In Wang Chenyin's personal cultivation of a hundred ninja with the bloodline of writing wheel eyes, now everyone is at least three hook jade writing wheel eyes.

And the number of kaleidoscope writing wheels is also ten, as long as the kaleidoscope writing wheel eyes are opened, then Wang Chenyin will be immediately promoted to the eternal kaleidoscope writing wheels.

With the Eternal Kaleidoscope Writing Wheel Eye, that is a shadow-level strength, but due to the lack of combat experience in these legions, the number of battles is insufficient.

Seeing the large number of gains, Wang Chenyin let his troops continue to expand.

"Now, it seems that the three tails have lost their human pillar power and started to wander in the land of water, this time, block the country of water and take this country." Wang Chenyin looked at the troops under his command and muttered to himself.
