After traveling through time, I became friends with Tsunade

When he was a child, Hashirama Senju hated war deeply. He always had a strong wish in his heart, which was to never let his two younger brothers die in vain on the battlefield.

During the brutal Warring States period, the average life expectancy of ninjas was even under 30 years old. The culprit for this tragic situation was the endless wars.

In a brutal battle, Hashirama Senju's youngest brother Itama Senju was killed by the Uchiha clan.

With a heart full of pain, Hashirama Senju came alone to the river where he met Uchiha Madara, and mourned the death of his brother by the river.

Just then, Uchiha Madara appeared. He asked Uchiha Hashirama why he was so depressed, and the two started chatting about it.

Uchiha Madara said with emotion:

"I used to have five younger brothers, too."

In this war-torn era, they all long to find a direction and do not want the war to continue raging.

It was also at this time that Hashirama Senju had already regarded Uchiha Madara as his close friend.

The two of them originally had several brothers, but the cruel war ruthlessly took their lives.

At this point, Uchiha Madara only had his younger brother Uchiha Izuna left, and Senju Hashirama only had his younger brother Senju Tobirama left.

The departure of their loved ones made them have the same idea, that is, to protect their younger brother even at the cost of their own lives.

At the same time they desperately want peace to come.

It was precisely because the two had similar tragic experiences and the same inner aspirations that they came together, became close friends, and determined to create a peaceful village that belonged to them alone - Konoha Village.

However, they were cruelly teased by fate.

In the fierce battle before the establishment of Konoha Village, Uchiha Madara activated the powerful Mangekyō Sharingan.

However, even so, he ultimately ended up being defeated in his duel with Senju Hashirama.

At the same time, Uchiha Izuna was unfortunately seriously injured in the confrontation with Senju Tobirama. Despite all efforts to treat him, he was still unable to be saved and eventually died.

Before his death, Uchiha Izuna gave his Sharingan to Uchiha Madara.

After that, Uchiha Madara obtained his brother's Sharingan, and thus possessed the eternal Mangekyō Sharingan.

......

"and many more......"

Jiraiya suddenly asked, "Yusuke, we almost know everything you said, why do you have to say it again?"

"Xiao Nan, do you know?"

Yusuke ignored Jiraiya's question and turned to ask Konan.

Konan shook her head. She had just been listening attentively when Jiraiya suddenly interrupted her.

She didn't believe that Yusuke would tell her these stories that didn't seem to be any secrets, so she immediately said to Jiraiya:

"Teacher Jiraiya, please shut up."

"it is good......"

Jiraiya forced a smile on his face and quickly raised his hands in a gesture of surrender.

"Then I will continue, Jiraiya, if you interrupt me again, I will break your arms and legs and carry you back. Don't worry, Tsunade will treat you."

Yusuke took a sip of hot tea, looking relaxed, as if he was just talking about something insignificant and not worth mentioning.

Jiraiya quickly shut his mouth tightly, as if he were a cicada in fear. He knew very well that Yusuke could definitely do what he said and could really do such a thing.

......

Therefore, Uchiha Madara, whose strength was greatly enhanced, led his entire clan again and launched a fierce battle with the Senju clan for his deceased brother Izuna.

However, even though Uchiha Madara was no longer the same as before, he was still defeated by Senju Hashirama in the end.

His extremely powerful complete form of Susanoo still seemed slightly inferior to that of Hashirama Senju.

In this thrilling duel, Hashirama Senju not only impressed Uchiha Madara with his extraordinary strength, but also with his unwavering ideals.

However, Uchiha Madara made an extremely harsh request. He wanted Senju Tobirama to be buried with his younger brother Izuna.

Senju Hashirama firmly refused to agree, but resolutely chose to sacrifice himself and urged the Senju clan and the Uchiha clan to unite in order to end this chaotic and turbulent situation.

In the end, it was Uchiha Madara who stopped Hashirama Senju's act of self-sacrifice, and the two of them worked hand in hand to cooperate and jointly established Konoha Village.

However, after the establishment of Konoha Village, there were huge differences in their ideologies that were fundamentally irreconcilable.

Uchiha Madara wanted to lead the Uchiha clan out of the village, but unexpectedly, no one chose to follow him at this time.

So, he resolutely chose to leave Konoha Village alone and silently advance the grand plan in his heart.

When Uchiha Madara returned again, it was shocking that he appeared with the extremely powerful Nine-Tails.

At this time, Uchiha Madara controlled the Nine-Tails and started a shocking battle with Senju Hashirama in the legendary Valley of the End, which shocked the world and made ghosts weep.

Although Uchiha Madara had the powerful help of the Nine-Tails at his side at this moment, he was still unable to defeat Senju Hashirama in the end.

Both of them fought without reservation and tried their best. The battle lasted until the last moment. Hashirama Senju defeated Uchiha Madara with his unfathomable strength.

When Hashirama Senju brought back the "corpse" of Uchiha Madara, everyone was convinced that Uchiha Madara was completely dead.

But in fact, he used the forbidden technique of the Uchiha clan - Izanami, at the painful cost of sacrificing a Sharingan, and finally succeeded in escaping. From then on, he hid in the dark, silently watching the changes in the entire ninja world.

No one knew that he actually bit off a piece of flesh from Hashirama Senju in the Valley of the End, and had awakened the Rinnegan long before World War II.

And Black Zetsu became his indispensable tool.

After layers of screening, he finally decided to transplant the Rinnegan to Nagato, a descendant of the Uzumaki clan.

After the destruction of the Whirlpool Kingdom, the remaining members of the Whirlpool Clan fled. Nagato's mother gave birth to Nagato in the Rain Kingdom.

Afterwards, Black Zetsu carefully planned that the Konoha ninja who was fighting with the Hidden Rain Village at the time rashly broke in and brutally killed Nagato's parents, thus activating Nagato's Rinnegan.

From then on, under the close surveillance of White Zetsu, Nagato began a life of wandering until he met Yahiko and Konan who were also homeless.

Until later, he met the three ninjas of Konoha who had just been given the title of Sannin - Tsunade, Orochimaru and Jiraiya.
