The former Ninja World.
The brief period of calm was like the fragile tranquility before a storm.
It was completely shattered with the outbreak of the Fourth Shinobi World War.
The starting point of this great battle was the disappearance of Uchiha Yan.
His disappearance was like the first domino to trigger a chain reaction.
This has pushed the already tense situation towards even greater chaos.
Five years have passed since the Uchiha disappeared.
During this period, Senju Tobirama served as the Acting Hokage.
In order to stabilize the situation, they did not choose to continue expanding like Yan.
Under Yan's arrangement, the Uchiha Clan also dutifully obeyed Senju Tobirama's orders.
The Konoha 12 and the rest of their classmates have all been promoted to Chunin.
Naruto begins to use the Nine-Tails ' power and learns Sage Mode.
With Sasuke's help, Orochimaru's strength also increased rapidly, and he even learned Kakashi's Chidori series of ninjutsu.
Others, such as Neji and Hinata, have greatly improved their strength.
The situation in Konoha is very good.
The power of the Nobles of the Land of Fire has been weakened to an extreme, making them utterly unable to contend with Konoha.
Beyond the Land of Fire, the Land of Earth and the Land of Wind began to expand, constantly encroaching upon other nations.
The once invincible Land of Rain, with Nagato's seclusion, now only its Land of Rain remains under the control of the Akatsuki Organization.
The remaining territory has been entirely ceded to the kingdoms of Earth and Wind.
As for the Land of Water, the Fifth Mizukage, the " Masked Man," also chose to go into seclusion.
However, Kirigakure was ultimately a large village, and its expansion never stopped.
They have already brought half of the Land of Land of Lightning under their control.
By now, the Ninja World world has been largely divided up by the four major powers of earth, wind, water, and fire.
Just when everyone thought the situation would gradually stabilize as countries developed,
The former god of the Land of Rain, ' Pain ', has emerged from seclusion.
His appearance was like a lightning bolt piercing the darkness, instantly shattering the seemingly stable order of the Ninja World.
That unique Rinnegan emitted a chilling light in the darkness, each gaze seemingly able to see through the illusion of all things in the world.
A frenzied storm instantly swept through the Land of Rain.
The ninjas who had once followed the Akatsuki Organization reunited under his command, their eyes once again burning with a thirst for conquest and power.
Pain stood on the high ground of the Land of Rain, overlooking this land that had endured so much hardship.
It's time to let the Ninja World know...
Your former 'god' is back!
First, we turned our attention to the Land of Earth Land of Wind.
These two nations, which profited greatly from the war, are now basking in a brief period of prosperity following their expansion.
Pain led the ninja forces of the Land of Rain in a surprise attack on the border Land of Earth and Wind.
" Bansho Ten'in " and " Shinra Tensei " ravaged the battlefield, and the defensive fortifications of the Land of Earth and Wind were as fragile as paper in the face of his power.
The border town was instantly destroyed, and the villagers fled in terror.
The ninjas from both countries were also in a sorry state in the face of Pain's overwhelming power.
In just seven days, they regained all the territory they had lost.
There are even signs of a reverse push.
During the battle, the Fourth Kazekage Rasa, was killed, and the Third Tsuchikage, Ōnoki, was seriously injured.
When the message reached Konoha, Senju Tobirama's expression was extremely grave.
An emergency meeting was convened with Konoha's elite ninjas to discuss countermeasures.
Meanwhile, in the Land of Water, the Fifth Mizukage, Obito, upon hearing the news of Pain's emergence from seclusion, accelerated his own plans.
But it will still take some time.
The only option is to first send a large number of ninjas to the Land of Lightning.
Under his command, the ninjas of Kirigakure set sail for the Land of Lightning aboard a massive warship.
The fleet of ships, which blotted out the sky, sailed on the sea like a group of ferocious beasts.
Standing in the Hokage's office in Konoha, Senju Tobirama looked out the window at the ninjas busily gathering, his heart filled with worry.
The impact of Pain's comeback far exceeded his expectations.
The tragic state of the Land of Earth Land of Wind cast a shadow over his heart.
After suffering heavy losses, the Land of Earth and Wind realized that fighting alone would only lead to their demise, so they quickly formed an alliance.
The remaining ninja forces from both countries joined together and rebuilt their defenses along the border.
However, Pain seemed unconcerned about their alliance and continued his frenzied attacks on the two nations.
That devastating power was constantly being unleashed on the battlefield.
Each time " Bansho Ten'in " is used, it will pull hordes of ninjas toward him.
Then use " Shinra Tensei " to bounce them off like cannonballs.
The screams of agony were incessant.
Despite the desperate resistance of the Earth and Wind Alliance against Pain's relentless attacks, the situation continued to deteriorate rapidly.
Their sphere of influence is shrinking, and their defenses are being breached time and time again.
Many ninjas lost confidence in battle, and fear spread through the ranks.
Pain, on the other hand, was like a tireless war machine, leaving scorched earth in his wake.
In the Land of Water, Obito led the Kirigakure's ninja army into the Land of Lightning.
They began to establish strongholds on the land of the Land of Lightning.
Their ambitions are blatantly obvious; they intend to use the Land of Lightning as a springboard to further expand their power.
The remaining resistance forces of the Land of Lightning were steadily defeated by the powerful offensive of the Kirigakure.
However, no one expected this.
Shortly after attacking the Land of Earth and Wind, seeing that the alliance between the two kingdoms was bound to break down, Pain turned around and attacked the Land of Fire.
The borders of the Land of Fire were instantly engulfed in war, and no one could withstand even a single blow from Nagato.
Jiraiya, Nagato's former mentor, was also severely injured in this battle and fell into a coma.
At the critical moment, Konoha used the Impure World Reincarnation Jutsu.
Many powerful, deceased ninjas were summoned, which barely managed to hold off Pain's attack.
On the battlefield, the Impure World Reincarnation ninjas clashed fiercely with Pain's forces, their battle cries shaking the heavens.
Although Pain's Rinnegan power was strong, it was difficult for him to quickly break through the defenses of these Impure World Reincarnation Tensei ninjas who were familiar with various ninjutsu and were not afraid of death.
The two sides remained deadlocked, and the situation persisted for a difficult month.
At that very moment, Obito from the Land of Water officially announced his departure from seclusion.
Upon his arrival, he led the Kirigakure ninja in a final sweep of the Land of Lightning.
The resistance of the Land of Lightning quickly crumbled under the powerful offensive of the Kirigakure, and the former resistance forces were wiped out.
The Kumogakure, which had a large number of ninja stationed there, was completely destroyed by Obito in a single move.
Countless people died or were injured.
This was the first time the Uchiha Clan had suffered such a blow.
Fugaku, Shisui, Tekka, and other high-ranking members of the clan acted decisively, leading their clansmen and ninja troops.
A fierce battle ensued with Kirigakure on the border of Thunder-Moon.
On the battlefield, the clash of swords and the gleam of ninjutsu intertwined, and blood stained the earth red.
However, the Fifth Mizukage Obito, was far too powerful.
Even with four or five Kage Level, including Fugaku, attacking together, they couldn't even stop his advance.
If it weren't for the fact that Yan left behind many things for the Uchiha Clan before he disappeared...
They might very well die on the spot in this battle.
