This is my ninja journey

The daytime was scorching hot, but the nights were incredibly cold.

In the twilight, the sounds of shouting, killing, and clashing weapons that had lasted from morning until now had ended. Only the scattered bonfires and the faintly passing flow of people remained.

They were tied together, surrounded by fully armed Konoha ninjas. There was no fighting spirit on their faces, just a group of walking corpses.

Suna had lost. Amidst the jeers and mockery, they silently walked towards the prisoner-of-war camp, fearing that they would be dragged out and killed if they didn't behave well.

On the nearby sand dune, the campfire crackled and burned. Otonashi and the others quietly watched the captured Suna ninjas walk into the distance.

Konoha always presented a glorious side to everyone. However, when you personally participate in the war, you will find many evils. Killing prisoners was a common occurrence.

"There are probably more than a thousand prisoners. The Third Hokage considered that other countries could not kill them all, and it would become a heavy burden for Konoha." Uchiha Shisui listened to the cheerful singing around him and said in a low voice.

A great victory had completely shattered Suna. However, the boy was more mature than his peers, and he saw the hidden dangers at a glance.

"You can't blame Lord Minato for being too good at fighting. Actually, it's good this way. The Land of Wind can only withdraw from the war." Otonashi shrugged. He didn't expect that the right-wing force with a heavy task would actually break through the defense line and circle around to the rear of Mount Kikyo, encircling Suna.

However, he also knew that Konoha did not produce anything. Ninjas were only responsible for fighting, and all supplies were provided by the Daimyo. The burden of a few thousand more mouths was neither big nor small. If the Third Hokage didn't have the idea of destroying Suna Hidden Village, he would have to sign a treaty as soon as possible and return the rice buckets.

So he saw forty or fifty-year-old men in the queue, as well as children who were more than a meter tall.

'The whole family in one wave? Unfortunately, it didn't go as planned, and the elite were almost all killed.' His gaze lingered on the face of a silver-haired little boy for a moment, and he patted Shisui's shoulder as he turned around:

"Don't think about it. These are things for the big shots to consider."

The boy's face was full of gloom and doubt. He sighed, "Yes, I just feel that this kind of killing each other is meaningless. We have already experienced two Shinobi World Wars, so why are we starting a third one?"

Now it was the summer of Konoha's 46th year. There had been three world wars so far, and the average peace time was less than ten years. It could be said that this world was either at war or preparing for war.

"Because the only lesson that mankind has learned from history is that it has not learned any lessons from history. The dissatisfaction of the victors and the hatred of the losers will make the world continue forever in a spiral of contradictions. No one can get an answer."

As a transmigrator, Otonashi himself could not find an answer. He returned to the campfire and sat down, without any trouble on his face.

If you are poor, you should take care of yourself. If you are rich, you should help the world. Do as much as you can, why bother to make yourself unhappy.

After the battle outside Mount Kikyo, he deeply understood that his strength was not enough. He needed teamwork to fight a Jonin, so what was the point of thinking about peace in the ninja world? He might as well calm down and think about how to find a way to learn.

The teacher's affinity was not right. Hyuga Hinata could indeed provide protection, but he couldn't learn his skills at all. The notes only contained insights and no techniques, and he couldn't quickly become stronger.

His swordsmanship had reached a bottleneck, and tempering his body was also a long-term process. Did he really have to study the skills of samurai? But even if he practiced to the extreme, he didn't know if he could step into the Kage level.

Otonashi was very distressed. He had four advantages in this body.

One was chakra volume, two was chakra control, three was his father's samurai inheritance, and four was the previous generation's insights. Each was not weak, but not exaggerated to the point of cheating. After more than ten years of study, he finally trained a jack-of-all-trades account. In this year, being able to fight with a Jonin could definitely be considered a genius.

But how could he be satisfied with being a genius in life?

The stars were brilliant, and the desert smoke was straight.

Shizune and Hinata had not yet returned. The two thoughtful teenagers seemed a little silent. Otonashi was about to take out his art book to relax his nerves when he caught a glimpse of green from the corner of his eye.

It was a boy wearing a green jumpsuit, with a watermelon head, his hands wrapped in bandages, and walking with a limp. He seemed to have experienced a hard battle, but his expression was still high-spirited. Noticing the gaze, he said something to the red-haired fat man leading the team, and climbed over with his hands as feet.

"Sure enough, Dad was right. Youth cannot be defeated by one setback!"

Under the illumination of the campfire, the boy clenched his fist in front of his chest, with tears in his eyes. It seemed that he had automatically imagined the inspirational plot of Otonashi's hard work after repeating a grade, and finally becoming famous in one fell swoop.

"Who is this person?" Shisui quietly approached.

"Might Guy, a former classmate. He was going to bite that Hatake Kakashi, but now he seems to be interested in me again." Otonashi sighed, remembering that when he was happy because he successfully repeated a grade, this guy was even sadder than him.

In terms of hard work, both of them had shed countless sweat on the playground of the ninja academy.

He grinned and just put his head on one hand and quietly looked at Might Guy. At this moment, Might Guy was only in the embryonic form of youth and was not as exaggerated as later. But after listening for a while, his eyes flickered a few times and he remembered something important.

Huh, can the lightning body be combined with the eight gates inside and outside? To raise the Jack of all trade?

A thought quickly flashed through his mind. Various memories from more than ten years kept appearing. In his previous life, even if he didn't watch Naruto, he had heard of the梗 [meme/inside joke] of 'Guy', 'almost kicked out the finale', etc. He also searched for 'Eight Gates Released Formation' on Baidu, but he had been busy studying the previous generation's notes for these years and couldn't find the time to open another subject, so he prioritized strengthening the foundation.

He knew that the so-called Eight Gates Released Formation was to open the passages that restricted chakra in the human body to temporarily obtain powerful power. The power depended on the caster himself, and it increased exponentially with the caster's own power.

Therefore, the power of different people opening the Eight Gates Released Formation was also different. It could be regarded as an 'internal' ninjutsu. And the lightning body he researched stimulated muscles, which was equivalent to 'external' horizontal training.

'My physical fitness is not much weaker than Guy's, and my chakra is dozens of times more. If I cultivate both internally and externally, even if I open the same gate, it will definitely be more powerful than him. This is a shortcut to quickly become stronger!'

Otonashi's eyes lit up. He had been training to death for more than ten years because he wanted to lay a solid foundation and accumulate a lot. He couldn't help but get up quickly.

"Thanks, Guy."

"Huh? What are you thanking me for?" Guy blinked, but saw that Otonashi ignored him and turned to run.

Otonashi didn't bother to care about the increasingly youthful fool. He ran between the camps, with a strange smile on his face.

Learning made people happy, and he happened to know where to find a way to learn!

"Otonashi, are you looking for me?" Hyuga Hinata, who had just finished the post-war summary meeting, saw his student running over in a hurry, and was a little surprised.

"Instructor, I have something I want to ask you for help!"

"It just so happens that I have something to tell you too. Sit down first." Hinata replied steadily, found an unoccupied campfire and sat down, and nodded approvingly when he saw that Otonashi was not in a hurry.

"First of all, I want to congratulate you on your promotion to Chunin. I have already reported your relevant combat achievements."

"Yes." Otonashi nodded solemnly. This was expected.

"Not arrogant or impetuous, very good. But in today's battle, what problems did you find in yourself?" Hyuga Hinata really had no ninjutsu to teach, but the elite Jonin, who was more than thirty years old, could also point out the future.

Otonashi was silent for a while and replied, "I am far superior to my peers in all aspects, but I am afraid that I am not capable of dealing with real masters."

This was the hidden danger of wanting everything. There was no absolute shortcoming, and there was no absolute strength. It was not easy to be targeted, and it was not easy to open Wushuang [Invincible/Unmatched].

"It seems that you have already realized this. There is no need to say more, I have already understood your intentions." Hinata reached out to stop the boy's explanation and said solemnly:

"I agree with your approach. Before the age of twelve is the time to lay the foundation. Your taijutsu and ninjutsu have already achieved good attainments. You should go further in this war."

Consider surviving first and then stepping into a stronger realm. Hinata did the same back then. Speaking of this, he sighed again.

"It's a pity that as a member of the Hyuga clan, I don't have any advanced ninjutsu to teach you, and taijutsu is not suitable either."

"Instructor, I already have a solution." Otonashi bowed to the taciturn Jonin and said solemnly, "So the student has a request--"

"Have you heard of the forbidden technique called Eight Gates Released Formation?"
