Naruto: We are invincible

##Iron Country##

It has been two years since Naruto, Gaara and Jiraiya left Konoha for their training journey, and Hinata has recently joined them. Hinata is a genius in medical matters, and is no slouch in combat. She has the Byakugan, which allows her to instantly diagnose any injury or illness suffered by anyone.

At dawn, Naruto, who was about to turn 16 at the age of 17, dragged his tired body back to the hotel after finishing a day of training.

"I'm back." Naruto said in a tired voice.

Hinata looked up from her notes. She had recently undergone a new change: a purple diamond pattern appeared in the middle of her forehead.

"Are you okay, Naruto-kun?" Hinata asked worriedly.

Although Naruto did not show any signs of illness, she, as a well-trained medical ninja, easily noticed Naruto's discomfort.

"What's wrong?" Jiraiya asked, and Gaara looked at Naruto with concern.

"I'm not sure." Naruto said as he stretched his body, "My chakra feels strange." He released a small amount of chakra, and the chakra at this time seemed very unstable and difficult to control.

"Let me see." Hinata said, opening her Byakugan.

She was surprised to see that Naruto's chakra was moving around as if it had a mind of its own. It seemed to affect his muscles and bones, but was mainly concentrated around his eyes.

"You're right, your chakra is indeed strange. Lie down and let me check it carefully." Hinata said. Naruto sighed.

"I don't think..." Before Naruto could finish his words, he suddenly fell to the ground and lost consciousness.

"Naruto!" they exclaimed, rushing forward to check on him.

Hinata was the first to arrive, and she examined Naruto with her Byakugan, trying to figure out what was wrong. She didn't understand why Naruto's chakra network was so active, which was too abnormal for someone who had just fainted.

His chakra seemed to be constantly changing and reconfiguring his chakra meridian system.

"Back off!" Hinata yelled, and the others retreated to avoid the chakra shockwave that erupted from Naruto's body.

His original dark blue chakra turned into a light silver, like moonlight. His chakra seemed to increase as well, as this new chakra seemed to be more concentrated than his previous chakra. His chakra felt so calm yet powerful, so free yet controlled.

Eventually, the chakra calmed down and everyone breathed a sigh of relief. Naruto groaned and slowly regained consciousness, but he felt a little stiff.

He slowly opened his eyes, and everyone held their breath. His original blue eyes, or rather his red eyes after opening the Sharingan, now had ripples. His eyes turned silver, with several concentric circles around the pupils, and the pupils seemed to have shrunk. Naruto's eyes had become the Rinnegan, the Eye of God, the eyes of the Sage of the Six Paths, the origin of all ninjutsu.

"Father..." Kyuubi whispered in Naruto's spiritual world.

"One day, you will all be guided to the right path." Kyuubi remembered his father's last words. "Could that person be Naruto?" Kyuubi thought to himself as he looked at Naruto's unconscious figure.

"That's..." Hinata stared into Naruto's new eyes, her mind full of questions.

"The Rinnegan." Jiraiya exclaimed. Of course, he had seen the Rinnegan before, but he had never seen it awaken in front of his eyes. Naruto opened his eyes dazedly, and then fell asleep again.

Hinata walked over and quickly checked him out, finding that he was just asleep but seemed to have a slight fever. She supported Naruto and took him back to the room.

"You have to be okay..." Hinata whispered as she grabbed Naruto's arm before snuggling up to him and falling asleep.

##Naruto's Inner Space##

Naruto woke up in his own mind space, and the Nine-Tails was looking at him curiously. The Nine-Tails was still trying to figure out how Naruto awakened the Samsara Eye. Those were the eyes of his father, the Sage of the Six Paths, and how Naruto did it was completely confusing to him. Especially since the Sage of the Six Paths always spoke in riddles when he talked to the nine tailed beasts.

"Kurouma, what happened?" Naruto sat up dazedly and asked. He felt a splitting headache, no, his whole body felt like it was on fire. Although it didn't hurt, this feeling made him very irritable.

"Tsk!" The Nine-Tails snorted disdainfully, "Do you know what you just awakened?" He looked at Naruto's confused expression and sighed helplessly.

"That's why I'm asking you, stinky fox. My last memory was talking to Hinata," Naruto explained.

"You just awakened the Samsara Eye, which is my father's eye!" Kyuubi said loudly. Naruto was stunned. He kept blinking, and his brain seemed to restart, trying to digest what he had just heard. He stood up suddenly and walked towards a nearby lake.

He immediately noticed his eyes. Instead of their usual deep blue or blood red, they had become a deep silver with concentric circles around the pupils. He looked around and found that he could see chakra in unprecedented detail. While it couldn't match the Byakugan in terms of detail, he seemed to be able to see chakra everywhere. The Kyuubi's chakra was red, while everything around him was rendered in varying shades of silver.

Naruto pulled the chakra out of his eyes, noticing that they reverted to his normal Mangekyō Sharingan, then the Sharingan, and finally settled on the deep blue pupils. He unlocked the next stage of the eyes, the final form of the Sharingan: the Rinnegan, the Six Paths Sage, the eyes of the God of all Ninjas.

This is the most revered of the three eye techniques, and it is also the most precious and powerful. In a sense, the Samsara Eye is like the natural evolution of the Sharingan, so there should only be two ultimate eye techniques. This made Naruto wonder why no Uchiha had ever been able to open the Samsara Eye before.

"My eyes are constantly evolving. I just mastered the Mangekyō Sharingan and a new form appeared," Naruto sighed, even though he was excited about the increase in power.

"You are a guy who doesn't know how lucky you are. Many people would do anything to get those eyes." Kyuubi scolded.

"I know, I know." Naruto waved his hand, "So," he cleared his throat and his eyes instantly turned into the Rinnegan, "What are the abilities of these eyes?" Naruto asked excitedly.
