Naruto: We are invincible

In the mansion of the Senju clan, Naruto and Hinata sat cross-legged facing each other, staring into each other's eyes, motionless, as if time had stopped.

The strange thing is that they both activated their own eye techniques, Naruto activated the Mangekyō Sharingan, and Hinata activated the Samsara Eye. The light blue Samsara Eye and the blood-red Sharingan complement each other.

Tobirama asked curiously:

"How long have they been like this?"

"Several hours," Itachi replied calmly, "They must be doing some special training."

"I see," Tobirama said thoughtfully, "How long do you think they were in there?"

"Time perception varies from person to person. In Tsukuyomi space, one second in reality is equivalent to 24 hours. As for Naruto, I don't know because his chakra amount far exceeds mine," Itachi replied calmly, "But... they have been like this for several hours and haven't even had lunch."

"If they are using a dojutsu similar to Tsukuyomi, then they should have been in there for... several years," Tobirama said in surprise after doing some mental calculations.

Just then, Naruto groaned softly and slowly opened his eyes. He and Hinata both stood up, maintaining the same posture for so long that their joints made crackling sounds.

Tobirama noticed that Hinata's hair had turned a dark blue and her aura seemed to have changed.

Naruto sat at the table, eating voraciously, and he almost used up all his chakra.

"How long?" Tobirama asked.

"Not only did we deplete my chakra, we also depleted the Kyuubi's chakra," Naruto said with a smile.

"If you count the Nine-Tails' chakra..."

"Two years," Naruto said, looking at the stunned Tobirama and Itachi, and added, "Two years, one month and 24 days to be exact."

"What did you do in there?" Tobirama asked in surprise.

"Training," Hinata replied while chewing on an apple.

"Is there anything we need to know?" Itachi asked.

"No," Naruto smiled and shook his head, "But...Hashirama is no longer the second strongest in our team."

"Really?" Tobirama asked in disbelief. Hashirama has powerful chakra and wood escape, how could he be surpassed by Hinata?

"That's right," Hinata answered affirmatively, but did not reveal any details. "Let them guess," she thought to herself.

"What about you? What did you do in there?" Tobirama turned to look at Naruto and asked.

"Prepare to defeat Madara."

## The next day, Hokage's office ##

"He won't agree," Tsunade said, standing by the window and looking at the scenery outside.

"I know," Hinata said softly.

"How do you know Naruto won't agree?" Tsunade turned around and asked puzzledly.

"We are conducting a very dangerous experiment and we need Naruto's power, but this experiment involves great risks and will take a long time. Naruto will definitely not agree," Hinata explained.

"Okay," Tsunade sighed helplessly, "Then try your best to convince him. You know that he has always attached great importance to peace."

"There is one more thing," Tsunade stopped Hinata who was about to leave and said, "Don't forget the Kage meeting. You and Kakashi have to attend it."

"Naruto isn't going?" Hinata asked, frowning.

"Our relationship with the Iwagakure Village is very tense. Naruto is too impulsive. I'm worried that he will do something bad."

"No, I think you should be more worried about what will happen if he doesn't go. In the past two years, Naruto and I have been training together in the spiritual world. He has changed a lot and is not as impulsive as before," Hinata said.

"Really?" Tsunade asked curiously, "Are you sure you're not biased?"

"Naruto has been gifted since he was young. He learns things quickly and has never lost in a battle, so he is so proud," Hinata explained. "Until that time, Madara appeared in front of him and took me away from under his nose, and he was powerless to do anything. This incident dealt him a great blow and made him understand a lot of truths. He has become mature and stable now."

"So that's how it is," Tsunade suddenly realized, she looked up at Hinata and said, "Okay, I get it."

Tsunade curiously asked Hinata what they had done in the two years in the dream.

Hinata said lightly that she was mainly developing her eyes to prepare for war, and also found time to study some other things.

Tsunade asked, doesn't it require practical training?

Hinata explained that she and Naruto's bodies were in peak condition and they just needed to wait for the right time to apply what they had learned in their minds without putting any strain on their eyes.

"Would you like to share your new abilities?" Tsunade asked slyly.

Hinata shrugged and revealed that she was the reincarnation of Hamara, and that Naruto's chakra activated her eyes, which was why the white hair and bone changes appeared. She didn't mind the new eyes, but she didn't fully understand the reason for the bone changes.

"I see." Tsunade nodded, signaling Hinata that they could begin, "Go ahead and bring him back when you're done."

Hinata bowed and left the office.

"That kid..." Tsunade looked at Hinata's leaving back, a smile on her face, "she always brings me surprises."

"Indeed." Shizune agreed with a smile.

## Meet up with Naruto##

"Are you serious?!" Naruto stared at Kakashi in disbelief, "Red Bean! You're going to marry Red Bean?! I thought you were just joking!"

"Okay, okay, Naruto, Anko is just a little... well, special."

"It's more than special, it's crazy, twisted, and sadistic! Should I go on?" Naruto teased.

"I'm a simple person, Naruto." Kakashi sighed helplessly and closed the book, "I saw it, I liked it, and I married it."

Naruto was immediately confused.

"Okay, okay, good luck to you." Naruto said with a smile after recovering from his shock.

At this moment, both of them felt a chakra fluctuation at the same time.

Water appeared out of nowhere, swirling in front of them to form a figure, and Hinata walked out of it.

"Hinata-chan!" Naruto ran over excitedly and started complaining to Hinata about Kakashi's marriage to Anko.

"Congratulations, Teacher Kakashi." Hinata said to Kakashi with a smile.

Kakashi nodded gratefully, this was much better than a certain blond kid.

"Okay, Hinata, we are both jonin now, you can call me Kakashi or Kakashi-senpai."

Hinata nodded and turned to Naruto:

"I need your help, are you free now?"

Naruto shook his head, indicating that he was free now, and asked Hinata curiously what she was going to do.

"Then follow me." Hinata motioned for Naruto to follow, then turned to Kakashi and said, "Teacher Kakashi, we're leaving first." After that, Hinata bowed slightly and left with Naruto.
