I Freakin Reincarnated With A System

"Beware Nii-san...!!!!! *Fire-release:-Great fire ball jutsu*..." Sasuke attacks Itachi with his *fire-release* but Itachi jumps upwards dodging the incoming attack.

"Haaaaaa.....take this." shouted Suigetsu as he swings Zabuza's Old sword which he left at his 'Grave'.

Itachi calmly twisted his body in mid-air avoiding the strike and immediately countering with a kunai stabbing his neck.

Suigetsu immediately liquify himself and the kunai passes through him. Itachi immediately abandons his kunai and made some handsigns.

"*Fire-release:- Great fire ball jutsu*..." launches a gigantic fire ball towards Suigetsu who curses out loud due to fear of being roasted "Shit..."

Suddenly a gray colored things zaps past Itachi carrying Suigetsu and narrowingly avoiding the incoming attack.

Itachi tries to put Suigetsu and Jugo in a genjutsu but finds himself unable to do so as Suigetsu is from Hozuki clan which are immune to genjutsu and Jugo uses senjutsu resulting in him also being immune to genjutsu.

Itachi knowing that genjutsu isn't effective decides to take a more aggressive approach as he activates his M.S.

"Karin keep tracking Nii-san and also tell us his location." said Sasuke as he activates his Sharingan , unsheathes his sword and rushes forward ,engaging in *Taijutsu* with his brother.

Itachi analyzes the situation and smiles 'My genjutsu won't work on anyone of them...one is fast enough to dodge my attacks and also save his teammates while one can go full throttle without worrying about injuries and the last one being able to pinpoint my location. Looks like he made this team solely to win against me but...'

Itachi suddenly rushes towards Sasuke and slashes down with his kunai only to be blocked by Sasuke's sword.

Sasuke rejoices after successfully blocking the attack but a second later his eyes widened as another Itachi appeared behind the one fighting him and smiled.

BOOOOOMMMMMM!!!!!!!!!!!!!.....

The clone fighting Sasuke exploded but Sasuke remained unscratched as Jugo suddenly appeared and blocked the blast by creating a shield using the *Curse-mark*.

Sasuke jumped backwards in the air while making handsigns and says in a low tone "*Lightning-release:- Chidori senbon*..."

Many small senbons are released towards Itachi who made handsigns and uttered "*Earth-release:-Mud wall*..." before slapping down his palms on the ground as he suddenly elevated upwards protecting him from the senbon.

Suddenly Itachi's eyes widened as he quickly bends backwards as a long lightning beam slashed the wall into two parts.

Suigetsu immediately uses this opportunity to swing down his sword at Itachi.

Itachi uses *Substitution-jutsu* avoiding the attack when he saw a flash of grey light attacking him extremely fast as he couldn't dodge and had to release some parts of his *Susanoo* as Jugo's punch chased into the strongest defense.

Itachi makes a sweeping gesture as a red hand formed and backhanded Jugo. After protecting himself he immediately stopped using his *Susanoo* as he didn't wanted to totally crush them.

Itachi uses *Fire-release:-pheonix flower shuriken jutsu* as small flaming disks made their way towards Suigetsu only to be blocked by a sword.

Itachi throws many shurikens towards Sasuke and Gang only to be countered by Jugo's canon as it destroyed the incoming attacks.

Suddenly blood dropped down Itachi's right eye as the viens inside his iris popped red.

"*Amaterasu*....." as soon as the voice fell black flames appeared on the battle field. Jugo sensing the danger from the flames immediately sped up to the max and flew out of Itachi's attack range with Sasuke and Suigetsu.

"Avoid those flames at all costs otherwise you will die."

"*Fire-release:-Multiple fire ball jutsu*..." launches towards Itachi who was currently at the top of the castle.

Itachi dodges the fires while recovering from using *Amaterasu* on such a wide range.

Itachi uses *Water-release:-Tsunami jutsu* on the area allowing the water carrying the black flames towards the opponents.

"Shit...." curses Suigetsu once again as he immediately retreats from the area whereas Sasuke used *Chidori-stream* to attack Itachi.

Itachi uses *Fire-release:- Phoenix sage fire jutsu* and covered it with *Amaterasu* forming a black Phoenix heading towards Sasuke.

Sasuke gritted his teeth and uses *Fire-release:-Great fire dragon jutsu* while covering it while *Chidori-current*.

Jugo and Suigetsu knowing that it isn't enough to stop the attack uses *Extreme canon* while the latter covered his sword in *Water-release* and threw it at the Phoenix.

BOOMMMMM!!!!!!!!!!!.....

Though the attack was stopped they too were weakened by using so much chakra. But suddenly Sasuke smiles as he ordered them to retreat.

"This is the end brother .....you lose."

"*Kirin*....."

Itachi looking at the incoming attack was astonished but suddenly smiled as he thought 'Sasuke draws natural lightning directly from thunder clouds to supplement the power of his strike and controls it with chakra. Unlike most techniques, which are based on the user's chakra, this one uses the natural lightning. But.....'

BOOOOMMMMMM!!!!!!!!!!!!!!....

Dust scattered everywhere ,all around when Karin asked "Did we get him..????".

"I think so...."

"Me too...."

"Finally....."

But then stopped when they heard a voice "Well think again....*Susanoo*..."

Dust cleared and the gigantic humanoid red colored figure came into view. It had the figure of an armoured soldier holding a sword in its right hand while a shield in other.

It was had a gourd which was connected to the skeleton.

"What is this thing.....this...this monster how in the hell are we going to fight it. Even Sasuke's *Kirin* couldn't damage it.

"How did it come to this."

"Damn it....*Gritted teeth*"

"No need to be frustrated Sasuke after all....you never should a chance hehehe he..." laughed Itachi as he slowly moved towards Sasuke with a crazed expression on his face.

'Damn it is this the end, No!!!! i promised Oni-san to become stronger and rescue Nii-san.....i can't lose.....never.' thought Sasuke as he suddenly heard a voice inside his head 'If you want i can help you save him.....i can help you defeat him....i can even help you in killing that masked man.'

'Really then help me ...i will do anything.' asked Sasuke desperately.

'Hehehehehe....let me take over for sometime.' said the voice.

'Ok.....' replied Sasuke as he closed his eyes and went in deep sleep.

'Hehehehehehehehhehehehehe.....'

Suddenly Sasuke's *Curse-mark* started covering his body as a giant Multi-headed snake formed from the mark.

"Sasuke what in the ....."

"Sasuke what is happening to you....."

"Sasuke..."

"Hehehehehhehehe..."

"So you have finally came out...............

Orochimaru."

"Hello Itachi....." replied a n.a.k.e.d man originating from one of the snakes mouth.

(A/N:-Fugaku's M.S ability is the reason for Sasuke to accept Orochimaru's offer remember it made a thing a rule and one who is affected would do anything for it to happen even sell their soul to Snakes like Orochimaru.)
