Chapter 10: Examination

The next day, after a 'nutritious' hospital breakfast, Boruto was immediately taken to the clinical trial room. He was placed in a full body scanner.

Once it was sure he was in top condition, he switched to a machine that specifically tests the head. This machine generally checks the brain's nerve impulses, but can also examine the eyes in depth.

After various computational calculations and chakra testing, Sakura came out of the test room to meet Naruto and Hinata.

"How is it, Sakura?" Naruto asked with concern.

"Don't worry, Boruto's eye health is normal. It's just …" Sakura hesitated to say.

"Just what?" Hinata chimed in impatiently.

"It's just that Boruto's eyes do have a kind of new membrane that surrounds the entire eyeball. This membrane is very strong and flexible so it requires several ways to damage it. Even after being damaged, this membrane has amazing regeneration power. Besides that ..." Sakura stopped again.

"Quickly, say!" Hinata snapped.

"Ahem, sorry. Also, when we did the chakra test, we found that this new membrane can absorb chakra. What makes me doubt is, I haven't been able to find the upper limit of chakra absorption from this membrane. And when I asked Boruto about his feeling when chakra got absorbed, he just replied a little itchy." Sakura concluded.

"Absorbing chakra?" Naruto frowned. Suddenly, he remembered the past. In the past, he once fought six people called Pain. One of Pain has the ability to absorb chakra. The thing that can make Pain do this is the Rinnegan's eyes.

However, Pain was too long in the past. Currently, there is a living source who has Rinnegan eyes, namely his own friend, Sasuke Uchiha. Moreover, the pink-haired woman in front of him was Sasuke's wife.

"Naruto, I know what you're thinking. However, I can't come to a conclusion yet whether Boruto awakens the same eyes as Sasuke. After all, Boruto's pupils didn't show any changes during the clinical trial." Sakura said.

"Then I'll try a few things. I'll be in!" Naruto immediately entered the room where Boruto was.

"Father? What's with that serious face?" Boruto was confused by his father's different gaze. It was rare for his father to have a stern face at home.

"Boruto, you stay lying down. I'm going to check something about your eyes." Naruto insisted.

Boruto hesitated a bit. After all, he didn't tell Sakura all about the condition of his eyes. Especially the incident where he could project the future for 5 seconds earlier.

However, his father might come up with something. Even though his father is not famous for his medical skills, Boruto has a hunch that his father will find a clue.

"This ... all right. What are you going to do?"

"Just relax your body. I will send chakra to your eyes. Don't fight back and tell me if something is wrong." Naruto calmed his son's anxiety.

Once the mood was right, Naruto poured orange chakra from his hands into Boruto's eyes. As Sakura had said, Chakra was indeed absorbed by the eyes, but this absorption was quite slow and not like the Rinnegan abilities he was familiar with.

"How do you feel, son?" Naruto asked.

"It's the same as before. Not too different."

Hearing his son's answer, Naruto frowned. Then, he closed his eyes to enter a subconscious mind state.

["Kurama, what do you think?"] Naruto asked in his mind.

["Naruto, I lost my connection to the chakra poured into your son. In my life, only twice have I experienced this. The first time was when half of my chakra was infused into Shikifujin. The second time was when your kagebunshin in Bijuu Mode was sucked into Kamui's dimension ."] The consciousness of the nine-tailed fox explained clearly.

["Yeah, I remember that too. When I fought Obito, I didn't feel the presence of my bunshin after entering Kamui's dimension. Do you think Boruto's eyes also create an independent space?"] Naruto asked.

["I don't know. It's just that, just before my chakra disconnected, I felt some form of energy conversion. This feeling was similar to when that Sasuke brat absorbed your chakra to convert it into his own. However, this conversion seems to have an unequal ratio. I feel that, no matter how much chakra your child absorbs, it will only be a little bit for new energy form. That means, this new energy has a higher level than the chakra we know."] Kurama explained.

["New energy? Then..."]

At this time, Naruto suddenly opened his eyes. Only, there was a difference in his pupils this time. The color of the pupils is yellow with a frog eye pattern. It was Sage Mode that Naruto mastered.

At his current level, to realize Sage Mode, he doesn't need to use clones to meditate to absorb nature's chakra. All he needs is a little bit of concentration to understand the natural energy around him and put it into his body.

"Nature chakra is also converted?" Naruto exclaimed in astonishment.

He thought that if Boruto's eye ability was similar to Rinnegan, nature's chakra would not be absorbed. After all, the nature's chakra is the highest level of chakra because it is the ability of heaven and earth. In fact, even if the Bijuu have great chakra, their strength certainly will not exceed the world itself.

Even if Juubi got resurrected, it is impossible to fight the world itself. The reason Naruto couldn't just use Sage Mode to fight the Juubi at that time, was because the nature's chakra that Naruto could absorb was limited. What limits Naruto is his own physique, not because nature's chakra is weaker than the Juubi.

"Father? What's wrong?" Boruto asked when he see his father confused.

"Boruto, think about it carefully. Was there really no difference after father tested you?"

Boruto fell silent. He suddenly pondered the details of what happened. Then he said, "I feel when daddy sends chakra, it itches me more than Aunt Sakura's chakra."

Hearing that answer, Naruto stopped sending out his chakra. His gaze also returned to normal.

"Boruto, is there still something you're hiding about your current state?" Naruto suddenly said with a serious expression.

"W-what do you mean dad? I told you the truth." Boruto stammered.

"Boruto, I'm going to tell you a secret. I can feel the negative feeling from someone. Hate, anger, fear, guilt, frustration, and more. Likewise if someone tries to hide something, he will feel nervous and worried. " Naruto said.

"Huh? Do you think I'm a three year old kid?" Boruto said full of scorn.

"You don't believe it? The Yamanaka clan has the ability to enter someone's mind. Do you think father's ability is not as good as theirs?" Naruto asked calmly.

"Th... that. W-father... I... I..." Boruto felt himself being ridiculous. How could his father be inferior to the Yamanaka Clan? The ability to sense negative feeling may sound fictional, but when coupled with the ability to read minds, it shouldn't be impossible.

"Okay, daddy won't force you to reveal the secret. It's just that daddy is worried about your situation. To be honest, daddy himself doesn't really understand the condition of your eyes. But daddy wants to ask one thing. How many people know about this incident?"

"Let me see. Father. Mother. Himawari might know a little. Then, Aunt Sakura and some helpful medical staff. Then, maybe Uncle Bald sells beef skewers. He asked me questions and I explained a little about a few things." Boruto explained. He didn't go into details on things with the bald guy. However, Boruto believes that with the Hokage's abilities, information like that would be easy to obtain. The only things he hide were his eyes ability which can see future projections and about mysterious sounds.

"Fine. Don't tell anyone about your condition. The less people know, the better. Then, we'll just periodically check on your condition. However, it isn't certain yet whether your condition is good or bad. Understood?" Naruto insisted.

"I understand."

After that, Naruto came out to meet his wife.

"How is our son?" Hinata asked worriedly.

"For now, he's fine."

"For now? Will there be any danger in the future?"

"I'm not sure myself. However, from now on Boruto will undergo periodic checks on his condition.

Sakura, I'll leave this matter to you. Remember, this matter will be a secret of the highest class! Make sure every staff is a qualified person.

Also, if you feel you are at a dead end, I can ask Grandma Tsunade. In fact, I can also ask Orochimaru to move." Naruto explained without hesitation.

Hearing Naruto's assertiveness, the two women were shocked. What surprised them even more was that even Naruto allowed Orochimaru to take care of this matter. That name is like a curse for the people of Konoha.

"Yes, Lord Hokage. I will try my best." Sakura straightened her body and spoke with determination. After all, if that big criminal was allowed to touch her patient, it would be an insult to Sakura's pride.

"Good!"
