Rosen felt that the only thing that could truly threaten Uchiha Madara was his Tenseigan Mode.
However, 10% Tenseigan Chakra was still too weak.
To contend with Uchiha Madara, he would need at least 20% Tenseigan Chakra, and that was just the basic requirement.
He also needed his base Chakra to keep up; otherwise, it wouldn't be enough to sustain the battle until the end.
And 20% Tenseigan Chakra meant that his constitution would need to double.
For the Uchiha Clan, their constitution and Chakra would greatly increase with each evolution of their Sharingan.
If they Awakened the Mangekyo or Eternal Mangekyo, their constitution would grow exponentially.
However, Rosen's current Tenseigan did not originally belong to him.
Moreover, it was Sealed within his body in the form of a Jinchuriki, so Rosen did not enjoy the benefits of the eye's evolution.
Besides his constitution, his Chakra needed to increase at least tenfold to be able to fight against someone of Uchiha Madara's caliber for an extended period.
His joint effort with Senju Tobirama this time barely gained a slight advantage.
That was also due to Uchiha Madara underestimating the two of them.
In the time that followed, Rosen and Senju Tobirama both entered a state of Cultivating and developing Ninjutsu.
As for Senju Hashirama's repeated invitations to battle, Rosen and Senju Tobirama pretended to be sick or went missing.
They still had a chance against Uchiha Madara.
But against an eternal motion machine like Senju Hashirama, they had no chance at all.
Time passed day by day, and finally, the day of the duel between Senju Hashirama and Uchiha Madara arrived.
This time, Senju Tobirama and Rosen did not stay in the clan territory but chose to go with Senju Hashirama.
The excuse was to watch the battle, but in reality, they were afraid that Uchiha Madara, that brat, would try another feint.
The battlefield this time was still the Sengokugawa River.
When the three of them arrived at the Sengokugawa River, Uchiha Madara had already arrived.
Uchiha Madara looked at Rosen and Senju Tobirama, his eyes still unable to hide his hatred.
"Look at your motherf***ing... I have no grievances with you, why are you looking at me like that? Do you believe I'll dig up your ancestral graves?!"
"Rosen, your cursing is truly vulgar," Senju Tobirama said.
"Isn't the ultimate goal of cursing a mental attack? It's like two Shinobi fighting, one only knows how to use B-rank and C-rank Ninjutsu, and the other suddenly unleashes an A-rank Ninjutsu. Then someone says, 'This guy's Ninjutsu is so vulgar.' Do you think that makes sense?"
"I think Rosen is right," Senju Hashirama nodded. "When fighting, using the strongest Ninjutsu is reasonable, and when cursing, using the dirtiest words is also reasonable."
Uchiha Madara took a deep breath, calming his agitated mood.
"Hashirama, why are they here? Do you still need help?"
"They are here to watch the battle. Regardless of the outcome, they will not interfere," Senju Hashirama said magnanimously.
"As if..." Rosen and Senju Tobirama muttered to themselves.
These two guys had no sense of public justice.
If Senju Hashirama were truly defeated, the two of them would definitely intervene.
"Let's begin," Senju Hashirama said.
Uchiha Madara had been Cultivating frantically for the past month, and his Cultivation had yielded impressive results: his Chakra had increased by 50%, his constitution had more than doubled, and his ocular power had also grown stronger.
Therefore, he was determined to win this duel.
Uchiha Madara immediately unleashed his Complete Body - Susanoo.
Senju Hashirama, Senju Tobirama, and Rosen all looked at Uchiha Madara in surprise.
Starting with a big Move, what kind of tactic was this?
Just then, the Complete Body - Susanoo simultaneously swung its four giant blades, but its attack was aimed precisely at the location where Rosen and Senju Tobirama were standing.
"I think you cursed him too lightly just now," Senju Tobirama said.
"Right?"
Wood Release: Hobi no Jutsu!
A wooden shield, made of two halves that could merge, appeared in front of Rosen and Senju Tobirama.
Before Uchiha Madara's attack landed, the wooden shield closed together, blocking Uchiha Madara's attack.
Senju Hashirama looked at Uchiha Madara and said, "Madara, don't make pointless attacks. Be serious!"
"Hmph!" There was some disappointment in Uchiha Madara's eyes.
His meticulously planned attack had still failed.
Wood Release: Wood Golem Jutsu!
A wooden giant over a hundred meters tall rose from the ground.
"Hashirama!"
"Madara!!"
"Do they always shout so loudly when they fight?" Rosen asked.
Senju Tobirama covered his face. He used to think that his older brother's way of doing things showed his spirit, but after Rosen said that, he felt so awkward that his toes curled up enough to dig out a two-bedroom apartment.
At their level of combat, the fighting style had evolved from a simple clash of Ninjutsu and Taijutsu to a grand, powerful display, seeing whose was grander, bigger, and stronger.
"Do you think it would work if I launched a sneak attack right now?" Senju Tobirama asked.
"I don't know if you'd succeed, but I know Hashirama would shove your head up Madara's ass."
"Then forget it."
In fact, they didn't need to worry; Senju Hashirama maintained a slight lead throughout the entire fight.
Senju Hashirama's innate Sage Body was fully displayed at this moment.
Never-ending Chakra and a constitution that healed without Seals.
No one could kill him on the battlefield.
Even this Ninja World Asura could not do it.
At the beginning, the two sides were roughly evenly matched.
Of course, the so-called even match meant that Uchiha Madara would attack first, and then Senju Hashirama would respond, selectively using his Moves.
He was afraid of hitting Uchiha Madara too hard and killing him.
This was his love for Uchiha Madara.
The battle lasted from morning until night.
Uchiha Madara finally ran out of strength, while Senju Hashirama was still full of energy.
"Madara, stop. Let's work together to end this war and build a Village without war, where all Families and civilians can coexist peacefully." Senju Hashirama extended a hand of friendship.
"Impossible! Unless you kill Senju Tobirama!" Uchiha Madara gasped, but the fierce look on his face remained.
Senju Hashirama threw a kunai in front of Uchiha Madara, closed his eyes, and spread his arms: "If it can soothe your hatred, I am willing to die in Tobirama's place."
Uchiha Madara's spirit suddenly collapsed, and he fell backward with a sprawl.
"If... if this is your wish, I am willing to follow your will." Uchiha Madara finally let go of his hatred, at least for now.
...
The war finally ceased with the handshake between the Senju and Uchiha.
With the two strongest Shinobi Clans united, an invitation was sent to the entire Ninja World: anyone, any Shinobi Clan, as long as they yearned for peace and were willing to let go of any past grievances, could join the Village jointly founded by the two great Shinobi Clans.
When this invitation was sent out, in just one month, a large number of Shinobi Clans and civilians began to arrive one after another.
The Hyuga Clan, the Sarutobi Clan, the Ino-Shika-Cho trio, the Aburame Clan, the Inuzuka Clan, the Mitokado Clan, the Shimura Clan, the Mito Clan...
They chose the flat river area of the Land of Fire as the final location.
And Senju Hashirama was responsible for negotiating with the Daimyo of the Land of Fire.
The Daimyo of the Land of Fire agreed to Senju Hashirama's request.
As a condition, one of Senju Hashirama's children would need to marry one of the Daimyo's children.
Why did the Daimyo of the Land of Fire agree?
It wasn't because he was magnanimous; it was entirely because Senju Hashirama said that if he didn't agree, the next person to negotiate would be Uchiha Madara.
Any political compromise is never because the policy itself is correct, but entirely because one side possesses enough power to force the other side to compromise.
The Village began to take shape. Rosen and Senju Tobirama stood on a cliff, looking down at the Village below. The major Shinobi Clans had demarcated their respective clan territories, and a tallest building was erected in the center of the Village.
That tall building would serve as the political power center of the Village.
"I never thought that Big Brother could actually persuade Uchiha Madara to let go of the past grievances between the two clans and work together to build a Village," Senju Tobirama said with emotion.
Rosen glanced at Senju Tobirama, silently took out a kunai, and then cut a bloodline across his left palm.
Senju Tobirama looked up at Rosen: "What are you doing?"
Rosen held out his left hand in front of Senju Tobirama; his palm had already scabbed over.
"Do you think a kunai can kill your older brother?"
"Uh... no, right?"
"Exactly. Your older brother never persuaded Uchiha Madara with his sincerity and magnanimity, but with his fist," Rosen said. "At that time, his subtext was actually, 'Madara, if you don't obey, then use this kunai to commit suicide.'"
"Oh, this..."
During a collective meeting of the Shinobi Clans, the Village was finally named.
And from then on, the Konoha Village Black Evil Force, which would influence the future of the entire Ninja World and the World's pattern, was born.
Senju Hashirama won the trust vote among the Shinobi Clans and became the first Hokage of Konoha Village.
The charm of Konoha lay in how every Shinobi Clan and civilian began to genuinely integrate into this large Family.
Even the volatile Uchiha Madara began to integrate into this large Family.
And the emergence of Konoha Village also meant that the Ninja World entered a new era.
Among the other four of the Five Great Nations, new Shinobi Villages were also established. Iwagakure of the Land of Earth was the second Shinobi Village to be established, closely following Konoha Village.
Then, Hidden Sand Village of the Land of Wind, Kumogakure of the Land of Lightning, and Hidden Mist Village of the Land of Water were successively established within two years.
And they all adopted the same model as the Land of Fire and Konoha Village.
In these two years, Rosen had completely perfected Light Release, and his constitution had also significantly improved. Now, Rosen's constitution could carry 17% Tenseigan Chakra.
The Four Shadow Demons tirelessly extracted and refined Chakra for Rosen. His current Chakra had doubled compared to two years ago.
In two years, Rosen's Combat strength increased from 22,000 to 30,000.
Rosen had estimated his strength; if he unleashed his Peak power, he could barely fight Uchiha Madara for a short time.
However, his constitution and Chakra could not sustain such a long period of high-intensity combat.
If Uchiha Madara's combat power were to be quantified, his Combat strength would likely be around 80,000, while Senju Hashirama's Combat strength would be around 100,000.
And on this day, Rosen received a mission.
