Naruto: My version is ahead of the ninja world

In the original timeline, whether Obito Uchiha's "Nine-Tails Invasion" was premeditated or a spur-of-the-moment decision was unclear even to himself.

But one thing is certain: this action was not a purely rational act with a clear objective. Rather, it was more like a rather emotional act of revenge. It was not an opportunity to collect the tailed beasts at the time. Obito Uchiha's attack on Kurama (the Nine-Tails) did not bring any positive benefits other than alerting Kurama.

The outcome of the Fourth Shinobi World War also demonstrated the error of Obito's actions. It was during the Nine-Tails' attack that the Fourth Hokage installed a suitable "battery" for his own son, the so-called "Child of Prophecy."

According to the metaphysical theory of gains and losses, or the actual principle of gains and losses or even equivalent exchange, the Fourth Hokage can be considered a cursed ninja—the fastest ninja in the ninja world is often late at crucial moments.

Obito Uchiha didn't care about his "death," but he resented the Fourth Hokage for not saving Rin Nohara in time, and he also resented the Fourth Hokage for not recognizing him as someone who had fallen into darkness immediately.

Objectively speaking, such resentment or bitterness is normal. After all, humans are rather selfish creatures and are used to making judgments of right and wrong based on subjective positions. Therefore, Obito believed that the Fourth Hokage, as a teacher, was both wrong and incompetent for failing to save his students.

It's normal for a person to have such thoughts, but if they plan revenge based on them, then things are a different story—what Obito has in his eye sockets isn't a Sharingan, it's clearly a Byakugan, because his behavior is a bit too ungrateful.

As for Kakashi Hatake, he was deeply mired in disappointment, confusion, and self-blame. More abstractly, following the Fourth Hokage's orders, he joined the directly subordinate Anbu, which cast a shadow over his entire ninja career, exposing him to even more of the village's darker side.

It's about fighting poison with poison.

After receiving Yugen's "reminder," Kakashi Hatake instantly remembered that he had talked about his teacher's family in front of Rin's grave. He clearly remembered mentioning the birth of a new generation of ninjas, war and survival, and Kushina Uzumaki's impending childbirth.

The hero's father committed suicide in a rather tragic way, his trusted teammates were buried by boulders, and the person entrusted to him was killed by him. Kakashi's heart was already broken; he was filled with self-blame and sensitivity. And now someone is telling him that the source of the Nine-Tails' rampage also lies with him... Uh...

Kakashi possesses a somewhat monstrous, solitary quality.

His gaze involuntarily drifted towards the enormous figure of the Nine-Tails. If what happened tonight was truly due to his carelessness, then he would become one of the greatest sinners in the history of Konoha.

So here's the question: would Kakashi consider this his responsibility?

Yes, he would during this period.

Seeing the sorrow and confusion in Kakashi Hatake's eyes, Yu Xuan's accumulated chakra and natural energy exploded instantly. He rushed towards his opponent like an arrow released from a bow, his momentum like a great fortune that could send countless fellow transmigrators to a designated world!

Speed, power, and momentum—in the blink of an eye, Yu Xian's figure pierced through the night, instantly crossing the space between the two. He didn't use any exquisite taijutsu; he simply used his right palm to block his left fist and propped up his left elbow, striking Kakashi in the side abdomen with an elbow strike.

The next moment, Yu Xian first heard the sound of a spine cracking, and then Kakashi's figure flew backward like a cannonball, spinning sideways. The enormous force even made his body make a low rumble as it brushed against the air.

boom!

Kakashi's body slammed into one of the walls, knocking down half of it.

Although Yu Xuan used a despicable mental attack and then launched a shameful sneak attack against a fragile young boy, ninjas are known for their ruthlessness and resourcefulness, and this action was concise and efficient.

Yu Xuan felt the impact was real; if such a powerful collision had landed head-on, the opposing ninja would have been confined to a wheelchair for life, even if they didn't die.

Yu Gen's plan was to gain experience points from this, but he still didn't know enough about Kakashi. In fact, Kakashi Hatake at any time could not be considered a simple cannon fodder. There was no doubt about his quality as a ninja.

A piercing and continuous howling sound rang out, and a ball of lightning appeared behind Yu Xian. Stimulated by the high-energy lightning release, a figure instantly closed in on Yu Xian.

What Yu Xian just communicated with was merely Kakashi's clone; the real Kakashi had been trying to flank him the entire time... The moment Yu Xian made her move was the moment she revealed her weakness.

The clone, struck by the attack, vanished with a soft "poof," while at the same time, Raikiri grazed Yugen's heart and lungs, piercing through his chest cavity.

Because Yugen could use natural energy to achieve special perception, he actually saw through Kakashi's methods first, but when faced with the Raikiri sneak attack, he didn't even try to dodge.

He simply twisted his waist, turning the attack from being hit from behind to being hit from the front.

Yu Gen admitted that there was an element of gambling involved. Well, the element of gambling wasn't actually that much. Faced with an "information source" like himself, it was almost impossible for Hatake Kakashi to directly kill him... As it turned out, he guessed right.

Kakashi, your Lightning Release isn't fast enough, nor is it ruthless enough...

"The legendary Raikiri is indeed very fast," Yu Xuan praised.

"You didn't try to avoid it."

Kakashi's expression was quite complex. On one hand, he had to fulfill his mission as an Anbu ninja and capture this suspicious individual who was clearly connected to the current chaos; on the other hand, he had to fight against his own mental breakdown... Hagen's accusations against him were definitely not without effect.

On the contrary, it should be said that the effect was outstanding.

"Because whether I attack or you attack, the result is the same." Yu Xian even smiled.

The intense lightning attack had already paralyzed his body, and theoretically, he should have no choice but to surrender at this point.

Kakashi didn't understand what Yugen was talking about. He just kept asking, "State your identity and tell me who the mastermind behind everything tonight is."

"Who else could control the Nine-Tails? You can guess..."

It was impossible to tell who had locked whom up in the current situation, because just as Kakashi was about to say something more, he felt a strange power surge into his body, and in the blink of an eye, his body became uncontrollable.

He couldn't even pull his arm back.

"Kid, natural energy is a great tonic..."

The idea of ​​getting pierced and then using natural energy to defeat the enemy is a PvP tactic that only works in dungeons, as it's too easy to mess things up and kill yourself.

Fortunately, it was Kakashi who was being messed with in the dungeon.
