Karl was a man who wanted face!
This was something that basically all the powerhouses and major forces in the pirate world knew.
Especially the Four Emperor pirate crews, Marine Headquarters, Mary Geoise, and the Seven Warlords of the Sea, and even the kings of the underworld, knew even better to what extent Karl wanted face.
After Karl occupied Gran Tesoro and annihilated the largest-scale Buster Call, he had used public opinion to whitewash that incident...
In this world, who would broadcast their battles to the whole world, specifically to let the world see their strength, and to earn the Berries of those fans?
From this, it could be seen that in Karl's personality, there was more or less a trace of narcissism, and the arrogance brought by great strength.
Now, Karl, who only saw Hagoromo Ōtsutsuki as his greatest enemy, was naturally no exception.
Doflamingo, who had received Karl's permission, immediately used his own method to announce the entry of the Golden Nation to the entire ninja world.
Rumble rumble...
Countless of the most top-tier cannonballs from the pirate world, which even Mary Geoise needed to purchase from the Donquixote Family, all landed on the city walls of the Land of Fire's border fortress.
Just like the islands destroyed by the Buster Call...
The defensive power of a mere border fortress naturally couldn't compare to an island.
Therefore...
With just two rounds of cannonball bombardment, the Golden Nation, whose cannonballs were fired from an unknown location, broke through the border fortress of the Land of Fire.
Immediately after, a scene that made the Konoha ninjas at the border fortress feel despair appeared.
After the "greeting" had fallen, a huge shadow that blotted out the sky suddenly appeared above their heads.
That huge shadow that blotted out the sky was none other than the floating Golden Island.
As if sensing the gazes of these people, the Golden Island in the high altitude suddenly descended vertically.
Under the wide-eyed gazes of the surviving Konoha ninjas, the Golden Island smashed heavily on the ruins of the border fortress.
In an instant, all the remaining presences disappeared from the Observation Haki perception of the Golden Island.
This was the Golden Nation's way of declaring an all-out war.
Directly and high-profilely occupying the enemy's doorstep to announce their existence.
...This was Karl's style.
Clearly, Karl's method of declaring war was quickly known to the Shinobi Alliance.
After all, the Land of Fire was the strongest among the Five Great Nations, and the border fortress of the Land of Fire had always been the most difficult fortress for the other four great ninja villages to break through in the previous two Great Ninja Wars.
Therefore...
When they learned that the border fortress of the Land of Fire had been occupied, and that the enemy was the Golden Nation, besides Hiruzen Sarutobi being both shocked and angry, the entire Shinobi Alliance was on alert.
Among the enemies of this otherworldly invasion, the one known as the World's Strongest Man, Dragon Knight Karl, was finally starting to act?!
And so...
Kumogakure, Iwagakure, and Sunagakure, the three great ninja villages, all silently mobilized their forces.
On Konoha's side, they were even more prepared for a great battle that could happen at any moment.
At this time, Konoha was unprecedentedly powerful.
Originally at its peak, it now had the resurrected Hashirama Senju and Tobirama Senju, two Hokage. Konoha, which was originally passed down to the Third Hokage, suddenly had three people in charge instead of one.
Before Tobirama Senju could return to Konoha and discover that his clansmen were almost all dead, and that the Senju clan, which was as famous as the Uchiha clan, was now a clan in name only, this man, who was as domineering as Madara Uchiha in some aspects, had, as the Second Hokage, suspended the duties of Hiruzen Sarutobi and the Konoha elders.
Especially Danzō Shimura's Root, which was no less than the Hokage's Anbu, made Tobirama Senju's gaze towards this disciple become unfriendly.
Facing their majestic teacher, whether it was Hiruzen Sarutobi or the ambitious Danzō Shimura, they did not dare to resist in the slightest.
And so...
After suspending their duties, Tobirama Senju sat back in the position of Hokage's assistant and continued to assist his older brother until the end of the world protection war.
While Hashirama Senju was dominating Kaido, Tobirama Senju had brought another great mountain back to Konoha.
That great mountain was none other than Madara Uchiha, who made Hiruzen Sarutobi and the others, and even the various great clans, feel suffocated.
Tobirama Senju was not a narrow-minded fellow.
Even Madara Uchiha, for the sake of the ninja world, had chosen to give up his dream and ambition. Tobirama Senju could also, for the sake of the world, put aside his prejudice against Madara Uchiha.
So with the help of Hashirama's cells, Tobirama Senju quickly restored Madara Uchiha's withered-tree-like corpse to its peak state at the Valley of the End.
Then, Tobirama Senju performed the Reanimation Jutsu on Madara Uchiha's corpse.
Madara Uchiha, who had just died not long ago, immediately returned from the Pure Land to the world of the living.
"...Although I hate you, I have to admit that your technique is superior to anyone else's in the entire ninja world."
The resurrected Madara Uchiha clenched his fist. Looking at his palm, which, although he couldn't feel pain, was full of power, he couldn't help but glance at Tobirama Senju beside him and said lightly.
"Your body is stronger than I imagined, and its compatibility with brother's cells is very high."
Tobirama Senju also said lightly, "I didn't expect that after the battle at the Valley of the End, you had secretly transplanted brother's cells and mastered Wood Release."
"That's right, and not just Wood Release..."
Madara Uchiha touched his chest, and a slight smile appeared on his lips as he kept them in suspense.
"Where is Hashirama? I need to discuss countermeasures with him."
After releasing his Yin Release chakra and not sensing Hashirama Senju's presence, Madara Uchiha immediately asked.
"Brother is in Kumogakure. He just captured a major figure from another world and is helping Kumogakure to stabilize the prison." Tobirama Senju replied, "He has a good junior by his side, who has learned the Flying Thunder God Technique, which no one has learned besides me."
"After brother is done over there, I believe he will be back soon."
"In that case, I'll go and investigate the real enemy's intelligence first."
Hearing this, Madara Uchiha disappeared from the dimly lit laboratory with a body flicker.
