3: Yin and Yang

Fathers younger brother must be Shikaku.

Nara Shikaku the future Jonin Commander of Konoha and also the Chief Strategist of the Fourth Greath Shinobi War.

After the talk that father and Uncle Fugaku have, they snuck out of the Uchiha compound and snuck inside the Nara Compound where Uncle Shikaku sleep.

Father handed me to Uncle Fugaku. I wonder why they didn't left me to the Uchiha compound.

But there is no use wondering as I will never know.

Father woke Uncle Shikaku.

I couldn't hear anything what they were saying nor I could see what they were doing in this dark night.

Being in an infants body is so troublesome.

-*-*-*-*-*-*-*-*-*-*-

Shikaharu walk near to his younger brother who was no older than 13 years old.

Before Shikaharu could walk even closer to Shikaku, he couldn't move.

He stared at his feet as he saw a shadow that connects to Shikaku.

'Shadow Paralysis Jutsu?!' Shikaharu thought shockingly, 'Shikaku's cautiousness have increase."

"Shikaku, it's me." Shikaharu said quietly but also softly.

Shikaku turned around as he widen his eyes after seeing his brother.

"Brother!" Shikaku said as rushed towards him embracing him.

It has been a long time that Shikaku saw his older brother, after his banishment from the Clan Elder so he is extremely happy seeing his brother.

Though even Shikaku who was now declare to be the sole heir of the Nara Clan, still doesn't know why the Elder's of his Clan banished him.

"Shikaku, it's been a long time how have you been?" Shikaharu asked with a smile.

"Even though my life has been such a drag. I'm comepletly fine."

Shikaharu chuckled to his younger brothers response.

All of his Clan members has always been this lazy, but nonetheless, the Nara Clan are known for having a high IQ making them terrifying.

Shikaharu look at his brother seriously,

Shikaku seeing his Older Brother's face was serious he ask what was wrong.

"Shikaku meet your nephew."

"Huh?! Meaning you have a child?!" Shikaku shockingly ask as his brother nod. "How?"

"Shikaku what I'm about to say to you can never be told to others. Understand." Shikaharu said clearly.

"Yeah."

"Do you remember 1 year ago when my banishment from the Clan happened?"

Shikaku had a painful look in his face as he nodded.

"The Elder of the Clan found out about my relationship with Sayori."

"What?! In other words they disapproved to your relationship." Shikaku predicted, making his brother nod.

Shikaku knew that this day would come, where those troublesome Elders would reject their relationship.

"Are there other's who knows this other than the Elders?"

"The only ones who knew about this are father, The Uchiha Elders and Fugaku."

Sigh...

Shikaku sigh. It wasn't his usual troublesome sigh, rather it was a sigh of relief.

It would tarnish the name of Nara and Uchiha Clan if the Shinobi's ever found out that Shikaharu who is a Nara and Sayori who is an Uchiha are secretly married.

And besides, the Uchiha Clan are too prideful to even let an outsider of their Clan marry their own.

"Where's this child of yours?" Shikaku ask. Shikaharu pointed at Fugaku's arms revealing a baby.

Shikaku walk towards his nephew as he ignored fugaku's presence.

Shikaku observed his nephew who stared at him. He has raven hair, and has eccentric eyes- his right eye is turquoise the same as brother and his left eye is yellow.

Shikaku took the baby in Fugaku's arms as he carry him.

"What's his name?"

"Uchiha Obanai." Shikaharu replied as he smiled.

However, Shikaku and Fugaku was confused. Before Fugaku could ask why does Obanai have to bear the Uchiha, Shikaharu explained.

"Sayori and I already discussed that he would take the Uchiha name..."

"Also..." Shikaharu paused as he stared at them.

"Fugaku you've become the Clan Head after your father died of an illness. And Shikaku in the next few years you're gonna replace father as a Clan Head so please, when I come back protect your nephew for me."

Shikaharu's words confused both Shikaku and Fugaku as they black out.

-*-*-*-*-*-*-*-*

After father knock both of my Uncle's.

He carried Uncle Shikaku to his bed.

And he took out a scroll, placing it on top of Uncle Fugaku's body. He raised his hand and form a half tiger seal,

"Seal!"

Wait! Wait! What?!

Did I see wrong or not?!

I never heard in the cannon that you could seal a living being.

My father must be a Fuinjutsu Master.

After he sealed Uncle Fugaku, he picked me up in the floor and suddenly I wasn't in Uncle shikaku's room anymore.

I was in the Uchiha compound!!

It hasn't even past a second yet!!

Is this the Flying Thunder God Jutsu?!

No it's impossible! I heard when it is your first time experiencing the Flying Thunder God Jutsu, you'd get dizziness and whatever the side-effects are.

But this Space-time Ninjutsu that father used is a bit different from the Flying Thunder God Jutsu.

I don't know the difference between the Flying Thunder God Jutsu and the unknown Ninjutsu that father use.

After father placed Uncle at his bed.

Father and I teleported to who knows where?!

-*-*-*-*-*-*-*-*

Being a Hashira in my last life.

I know everything about the Concentration Breathing.

Since this infant body of mine still doesn't know what a Concentratiom Breathing is.

I should start training now.

I concentrated on breathing, greedily sucking at the air.

At first, my entire body felt slightly warmer, but the pain my lungs are going through was unimaginable.

When I first start doing the Concentration Breathing in my last life.

I only felt a little pain.

But now.

It's like being bitten by a bullet ant and then lit on fire and then being cooled by an entire tank of liquid nitrogen.

The actual process is like this, I breathe, the incredibly piercing ice-cold air in the night goes in my lungs.

I then use all my strength to try and let the oxygen flows into every cell of my body.

I breathed with all my strength until my lungs were squeezed out and slowly let out my breath.

It's like how a stress ball would deflate when a 1000 pound anvil falls on it.

And then you slowly lift the anvil away from that stress ball.

I only persisted for about 3 rounds of breathing, which was around a minute and a half.

My lungs hurt so much that I forgot about the freezing winds for just a minute.

2 years later.

My life for the past 2 years with father were great.

He taught me the Shadow Paralysis Jutsu that he recreated Shadow Release.

It turns out that the Jutsu father used years ago is called,

Shadow Release: Shadow Exchange Jutsu.

He explained that to use the Shadow Exchange Jutsu, the user has to mark a Kanji Shadow Seal from a living being or non-living being,

And the effects of this Jutsu is that the user can exchange location where or who they have mark the seal on.

But there are limits,

How many times you have to use it in a day or week,

How far the location is,

And much Chakra does it consumed.

-*-*-*-*-*-*-*

When I was 2 years old Father, I started speaking fluently causing father to cry from joy.

Weeks later Father said that train me and explained that the Nara Clan techniques utilize Yin Chakra more so than Yang,

But the most important thing is having a good balance of Yin and Yang chakra,

If you have too much Yin Chakra you will easily tire out but have a greater mind than others while if you have more Yang Chakra you would be more energetic but less academically capable,

Yin Release uses spiritual energy and Yang Release uses physical energy, which are the two components of  Chakra.

Luckily for me, father said that mother, despite being from the Uchiha Clan she has High Yang Release, and father being from Nara Clan he has High Yin Release.

Meaning I will have high balance in Yin and Yang Release.

There are difference and similarities of Yin and Yang Release

The similarities of Yin and Yang Release is that they are a nature transformation that exists outside the five basic elemental natures.

And the difference are that Yang Release uses physical energy to control vitality, granting life to forms that have none.

While, Yin Release uses spiritual energy to control imagination, creating form out of nothingness.

"The easiest Jutsu in the Nara Clan is the Shadow possession jutsu,"

"It allows you to connect your shadow to another's and make them mimic your movements,"

"The first thing you need to learn is how to manipulate shadows which are done by using the Rat hand seal and making your Chakra fuse with the shadows,"

"From there on you will mostly be on your own since you need to experience the control to know how to manipulate your shadows,"

"At first you will most likely not be able to control the shadows but you will get better with time."

I was just about to go and do what he'd explained earlier not after he called me out,

"Nai-chan, I'm telling you this so that in the future you'll be able to train comfortably, not because I wanted to rush you..."

"... For now just remember all what I'm saying to you." Father said warmly as he ruffled my raven hair.

"Ok, father."

"Today's training is first stretching, then second we'll run together..."

A Year Later...

I have mastered the Total Concentration Breathing.

I tried mastering the Full Focus Concentration Breathing.

'Who the fucking hell gave this technique a shifty long name...'

'From now on the Total Concentration Breathing is called; TBH. And the Full Focus Concentration Breathing is FFCB...'

Anyway training the FFCB,

Is terribly a bad idea. Every all night and all day I trained the FFCB.

Causing me to automatically cry from pain,

Having no control or suddenly pooping,

Which gave my father a headache.

Sigh...

For the past year father have been only training me physically.

He still didn't let me awakened my Chakra or explain the details.

I stopped walking for a bit.

Who the hell attack a kid in a broad daylight,

Oh. Right, I've completely forgotten that I'm in the Shinobi world.

But father and I from what father calls temporarily live here in the

Land of Iron.

I don't know how father was able to let that old Mifune to agree at his request but I have a feeling they are very good friends.

Didn't all Shinobi's and Samurai agreed not to meddle in each other affairs.

Whoever this attacker of mine is, is completely stupid.

Is the attacker waging war or something.

I was about to go to my house and let father take care of it.

Seeing father training with me, I know that he's a strong Shinobi.

But before I could even proceed my plan.

The attacker is unexpectedly stupidly smart. He did not even gave me a chance to walk away as he attacked me.

The attacker's body was covered in black cloaks and his face was covered with an anbu mask.

I reflexively dodge every shuriken that was thrown at me.

I know that I'm strong but not in this body.

I could predict the attacker's movements as he kicked me in the stomach.

Just because I could predict his movements, doesn't mean I'm physically strong enough against him.

But lucky for me father trained my mind.

I rolled away and grab a bunch of shurikens.

Xiū xiū xiū

The attacker tilt it's head. However, that was all part of my plan.

I never gave the attacker a time to react, I quickly throw the shuriken I had towards his chest, arms and legs.

After that I took out a kunai, as I dashed at the attacker at full speed.

I aimed at his heart.

The attacker fall to the ground. I inspected its mask.

It wasn't Root, I sigh.

It wasn't a sigh of relief, rather it was a sigh in utterly disappointment.

If this attacker is part of the Root, I would torture him and order him to tell me all about Danzo.

Now to reveal my attacker, and ask him why did he attack me.

After I took off the attacker's mask.

I widen my eyes, as I dropped the mask.
