Reborn as Madara's grandson in Naruto

"I'll play with you. After all, I don't want anyone to go overboard with me for some bad reason.

I took the candy from the Hokage, opened the package and started eating. damn it! This is the cheapest candy in the village. I kept these thoughts to myself while smiling at the Hokage.

"Thank you, Hokage-sama. Thank you for the candy."

"Now! Now don't be so formal with me. Just call me Grandpa Hokage, since that's what most of the kids in the village call me."

Hiruzen smiled softly at Izuna and spoke to him.

"Okay! I will remember it, Hokage-sama...I mean Grandpa Hokage."

"Okay! Now let's test the nature of your chakra."

When I heard these words, I started to get restless. I have an affinity for each element and know what kind of reaction the chakra paper will give when I infuse chakra with chakra.

Akira nodded towards the Hokage, took out a chakra paper from his pocket and handed it to me. I looked at my father and muttered to himself,

"Father! I'm not feeling well. Can we examine the chakra paper another day?"

Akira heard my words and had an uneasy expression on his face. He hesitated for a while, but finally made a decision.

"Okay! I will talk to Fugaku and Hokage-sama."

I pretended to be unwell, collapsed on the floor, and nodded happily to my father. My father caught me immediately while talking to hiruzen and fugaku,

"Izuna is not feeling well. I will take him home and he will be fine after resting for a while. If you want to know about his chakra properties, I will test it and tell you later."

Huang Quan waved his hand and said:

"Just take him home to rest. It's no big deal. You can report it at any time."

Akira nodded to Hiruzen and Fugaku, and rushed towards the Uchiha clan with me on his back.

"What happened to this kid suddenly? I only gave him six-month-old candy to eat, and I usually put it in my pocket. Is there something mixed in the candy, or is it stale. Hiruzen thought about it.

Meanwhile, in the nearby bushes,

‘Damn it! The Uchiha boy left without showing his true chakra nature. I have to put rootanbus to monitor these two children. Although it is impossible to monitor them within the Uchiha clan, it is enough for me to be able to track their whereabouts outside the Uchiha clan compound. If I can control these two Uchiha boys, then I can control the entire Uchiha clan in the future. The Hokage's location will soon be within my grasp.

Danzo signaled his root Ambas to retreat to the headquarters, and he disappeared from his place. Yagami and Shisui flashed out of the training ground together.

My father and I returned home as my mother welcomed us back. Worried about seeing me lying on my father's shoulders, she asked,

"Izuna, are you okay? Mom is here to take care of you."

Aiko snatched Izuna from Akira and began to hug him.

"My child is a real ninja now. Your chakra unlock must be tired. Go and rest. Mom will prepare your favorite food for you for dinner tonight.

I pretended to be tired and slowly staggered towards the bedroom. As soon as I entered the room, I jumped on the bed and shouted silently in my mind.

"Finally, I can practice ninjutsu. Gone are the days when I had to wait helplessly for ninjutsu training. Now which element should I start with.

I started thinking about it because there were so many options to start with. The father is responsible for the art of fire and thunder. I can ask Uncle Yagami to train me in Fuinjutsu. As for the Earth Water Ninjutsu, I put it aside until I entered the academy.

Now, this leaves me with other elements that are uncharted territory for me. In addition to the elements mentioned in "Naruto", I also know some other elements, such as the element of space, the element of time, the element of light, the element of darkness, the element of void and the element of chaos. Other elements I still don't know.

I can't practice in the elements of space, time, void, and chaos because they are too complex and I need some kind of outside help or assistance to solve them. This left me with elements of light and dark. I think light elements are easier to master than dark elements.

The hours I spent studying the properties of light in physics will definitely be put to use here. When I was furiously preparing for the college entrance examination in those physics books, I never thought that something like this would happen.

Light can be used in many ways. I can adjust its wavelength to control the impact on the surrounding environment. There are infrared, ultraviolet, gamma rays, microwaves, radio waves and more, the possibilities are endless. But I now need to figure out my necessity.

I wanted to evolve my Sharingan as quickly as possible without everyone present seeing it. Maybe I should try to master optical illusions first. I can use the phenomena of refraction and dispersion to bend light around my eyes, creating an illusion to hide my Sharingan.

But there was a catch with this technique, any Uchiha or Hinata would be able to see the chakra injected around my eyes and figure out what the jutsu was for. I had to find a way to mess with their senses.

I lay in bed trying to figure out a viable way to hide my Sharingan.

'Wait a moment! I'm retarded. How could I forget the occult? It will easily sync with light elements and enhance genjutsu. So, I can use light elements to project a small genjutsu around my eyes to make people believe that my eyes are normal and not a Sharingan. And the best person to learn genjutsu is at my home. Mom would be the best teacher to teach me genjutsu.

I locked the room from the inside, activated the Sharingan, lay on the bed, and began to recall the hand seals required for the fire element: the big fireball technique. I wanted to surprise my father with this jutsu on my first try and force him to teach me more jutsu.

Learning shadow clones and multiple shadow clone ninjutsu would be a good start as it would exponentially increase my chakra training and other types of training. Now, I should only train in basic chakra control techniques.

I reached into my pocket and pulled out a bunch of leaves I had picked earlier. I will practice the "Leaf Concentration Exercise" until dinner. This is a very good exercise for a beginner like me who knows next to nothing about chakra control. I place the leaf on my forehead as I begin to center my chakra and focus on the center of the leaf. This is a common exercise taught in the academy and I didn't want to spend most of my time in the academy learning beginner stuff. Kakashi graduated from the academy at the age of 5 and was promoted to chuunin at the age of 6. This news shocked the villagers, who marveled at Kakashi's abilities. Kakashi had so much potential and talent that was wasted on his grave.

Kakashi is nine years old now, five years older than me. Uncle Sakumo is still alive, he has not completed his mission and committed suicide. I wanted to prevent him from dying if possible. In the future, he might be a good choice for Danzo. I don't know the necessary details of Uncle Sakumo's death. But in the anime, Kakashi started acting like my high school principal two years before the Third Shinobi War, complaining about the rules all the time. So, I still have two years left, maybe I should interact with him more.

This reminds me of the upcoming Third Ninja War, and maybe I should participate in it from the back lines to broaden my horizons about the Ninja War. After all, I'm still new to all this killing. Operating on a corpse is one thing, but killing an actual living person is another. My hands must be stained with blood, I want to make a name for myself in the ninja world.

And in the future, I will also have to face Grandpa. I don't want to have any interaction with Black Zetsu until the Fourth Ninja War. Maybe we could deal with him earlier, but that would alarm the Kara organization headed by Otsutsuki Isshiki. He is a terrifying figure that Kaguya cannot compare to.
