My understanding is against the heavens, I created the Sharingan training method

Traveling into the future is easier than traveling into the past.

Because the future is uncertain, but the past is determined.

If you are in an area where time flows slowly, such as a black hole, the time outside will be much faster for the person in the black hole.

When he leaves the black hole, it can be seen as traveling into the future.

But it wasn't that simple in the past.

In the purely physical world, Gen Uchiha felt that there was no way to travel through it.

In the fantasy world, this may not be the case.

Since the world of Naruto can exist, then those worlds such as the Great Desolate World, Zhe Tian, ​​and Immortal Sword probably also exist.

In these worlds, it is possible to travel back in time.

"Is that so?"

Naruto and the others didn't understand, but Kakashi roughly understood: "So, this is not the past of our world, but another ninja world. Am I right to understand this?"

"Completely correct!"

Gen Uchiha gave him a thumbs up.

Sure enough, Kakashi still has a brain, unlike Naruto beside him, who is stupid.

Kakashi didn't frown and said, "Then how do we return to our world?"

"Of course we still have to rely on the power of dragon veins!"

Gen Uchiha replied directly, and then continued: "However, the Dragon Veins cannot be used by you for the time being. I still need to check it!"

"It is estimated to take ten days and a half;"

"During this period, I need you to stay here and wait!"

"When I finish my research, I will send you back to your world."

The main reason is that he and Kakashi and others who have traveled through time also want to study it, so as not to be unable to realize the ability to travel through parallel worlds.

"Is that so?"

Kakashi listened and did not refute. He nodded directly and said: "Okay! Then I will trouble you next."

"Speaking of which, you said before that the one in your world is stronger than me. Is that true? Can you tell me about his situation?"

"Also, nothing has happened to Obito and Lin here, right?"

When he said this, Kakashi stared at Gen Uchiha with his eyes fixed on him, feeling very uneasy.

"Hehe! That's right!"

Uchiha Gen smiled knowingly after hearing this and said: "With my help, Kakashi in our world has reached the elite Jonin level!"

"And it's not relying on something like the Sharingan, it's purely relying on Hatake swordsmanship and taijutsu!"

"Besides, Obito and Lin are indeed not dead!"

"Also, the three battles on our side were ended by me a few months ago!"

"The mastermind behind the death of Obito and Nohara Rin in your world has also been killed by me in advance in our world!"

"So, there is a high probability that they will not follow the old path of your world々々!"

"In fact, not only them, but your father in this world, Sakumo-senpai, is still alive and well!"

"It's also my fault!"

It feels good to change these regrets.

"what?"

Although Kakashi was shocked when he heard what happened to Obito and Rin before, he could still keep calm. But when he heard that his father was still alive in this world, he couldn't hold back and quickly asked nervously and expectantly. : "Is what you said true? My father in this world is still alive?"

"nature!"

Gen Uchiha nodded: "If you want to meet me, I can send you there at any time!"

"It just so happens that you from our world are back today, so I can meet you by the way. I'm looking forward to meeting you! Haha!"

He was very curious about who would win if the two Kakashi fought.

"Is this... going to be too much trouble for you? Is there enough time?"

Kakashi asked nervously and expectantly.

Forget about himself in this world, he really wants to see his father who is still alive in this world.

He really had a lot to say to him.

I want to ask him.

"Okay! Soon! I have mastered the art of Flying Thunder God, and I can send you there at any time!"

Uchiha Gen smiled and waved his hand.

"Eh?"

Kakashi was shocked after hearing this: "Flying Thunder God? You actually mastered the teacher's technique? Are you the disciple of the teacher in this world?"

"of course not!"

Uchiha Gen curled his lips and said, "That guy Minato can't become my teacher yet!"

"My teacher is Tsunade-san, and my name is Gen Uchiha."

"Ok?"

After hearing this, Kakashi looked at Uchiha Gen with wide eyes and said in disbelief: "You are actually an Uchiha? How is this possible?"

"Tsunade-sama would actually accept you as your disciple?"

Kakashi found it incredible.

This is Gen Uchiha!

Who doesn't know the conflict between Senju and Uchiha.

Tsunade-sama might not care too much because Senju no longer exists, but it is still unimaginable for her to like Uchiha and accept one as her disciple.

"Why not? After all, I'm such a genius!"

Gen Uchiha spread his hands and said.

Kakashi: "..."

Haruno Sakura: "..."

"What a stinky ass!"

Naruto was also very speechless and said, "I feel like you're worse than Sasuke! The Uchiha is also in trouble! But isn't Sasuke the only one left in the Uchiha?"

Obviously, with this guy's brain, he didn't understand the situation at all.

Gento Uchiha was very amused.

At this time, Kushina came over and looked at Kakashi and said: "You are actually the grown-up Kakashi? He's completely crooked!"

"This strength is not worthy of your talent and reputation. Have you failed over the years? Have you made no progress at all?"

"The key is to have this Sharingan. It's stupid to not be able to close it. Why not use sealing techniques to create a seal that can be opened and closed at any time?"

Completely incomprehensible.

This consumes a lot of chakra every moment. No wonder this middle-aged Kakashi is so strong and his body is so weak.

Kakashi was speechless after hearing this: "I'm so stupid, I'm so sorry!"

She didn't know if it was Kushina's misunderstanding. She always felt that the Kakashi in front of her was a little afraid of her.

Kushina immediately understood the reason, and narrowed her eyes slightly: "It seems that you know me in your world, and you are even afraid of me! Tell me, what kind of person am I in your world? How am I doing now? Already?"

"You should know my name, right? My name is Uzumaki Kushina."

"really!"

Kakashi understood immediately after hearing this. He touched the back of his head in embarrassment and looked at Uchiha Gen: "Well..."

"Better stop talking!"

At this time, Uchiha Gen quickly interrupted: "Life in different worlds must be different, so there is no need to ask questions!"

"I will send you to Konoha to meet your father now!"

After saying that, Gen Uchiha sent Kakashi away with a wave of his hand without waiting for Kakashi's reply.

"Hey! Where did you take Kakashi-sensei?"

When Naruto saw it, he immediately shouted.

"Just let him go see his father. He will be back in a day or two at most. Just stay here, you little brat!"

"If you mess around, be careful and I'll beat you up!"

Uchiha Gen narrowed his eyes and looked at Naruto.

"I do not care!"

Naruto immediately became furious and pounced directly on Uchiha Gen.

"Bah!"

The next moment, Uchiha Gen snapped his fingers and froze Naruto into an ice sculpture.

"you...."

Haruno Sakura and Sai were shocked when they saw it. They looked at Gen Uchiha with wary expressions and asked, "What exactly do you want to do?"

"Nothing! I just want this kid to be quiet!"

"You should go to Kakashi's side! Don't cause any trouble for me!"

"As punishment, this kid will stay here for now!"

After saying that, without waiting for Haruno Sakura and the others to agree, he waved them away again.

Then they started to study around Naruto.
