why is naruto so strong!?

as the five clones jump towards me I spin around and I hurl 5 shurikens killing all five of them as the real naruto jumps towards me I jump towards him and we clash fists 'looks like he empowered his fist as well I think as our chakra imbued fist clash creating a mini shockwave making us fall to the water below "Katon: Hōsenka no Jutsu" I say as six fireballs rush towards naruto who begins to do hand signs "water style: water bullet!" naruto yells as he shoots a large bullet of water that clash's with my fireballs making steam rise as I turn on my Sharingan.

'When the hell did naruto learn water jutsu's and how is he keeping up with me the original Sasuke was moping the floor with him and I'm much stronger than the original' I think as I duck under a punch that came from behind through the steam as the punch sails above my head I do a back kick kicking naruto in the stomach making him turn to mist 'i seem to have changed the timeline me doing everything during missions made naruto feel week ad train more' I think as the smoke clears I see naruto charging a massive Rasengan 'he already can make a massive Rasengan?' I think as I charge a Chidori and I use half my mark for a boost making my Chidori turn purple-ish.

as I and naruto charge at each other, we clash but I am at a bit of a disadvantage as naruto begins to overtake me "tch" I say audibly as I begin adding more chakra to my Jutsu pushing us to a stalemate, as the clash stays a stalemate our chakra begins to become unstable as I notice the chakra get ready to explode with my Sharingan I brace myself and I make my body tougher by using chakra to harden my skin and muscles *booooooom* an explosion rings out as I am flung away.

as I get up to a crouch on the water I am punched in the face by a red-eyed naruto 'when did he use the Kyuubi's chakra' I think as I'm flung away but before my back can hit the rock see an orange blur charge towards me but with my Sharingan, I accurately parry a blow heading for my stomach as I kick the blur making it turn to smoke 'he's moving even faster than Orochimaru did in the forest' I think s I get into a fighting stance I put my senses to the max making my Sharingan glow 'he is so much stronger than his cannon self if I was the original Sasuke I would have been overwhelmed' I think as five naruto's charge at me they begin to blur.

as the first reaches me I lean back from a heavy swing that leaves a shockwave through the water as I lean back use the close as a stepping stone first kicking it in the face and then using its body to jump away as it turns to smoke three more blurs charge towards me "fire style: fireball Jutsu!"I yell as the three blurs are hit by a fireball once I see them gone I relax my muscles but I am smashed I the stomach 'shit I forgot about the last clone' I think as I'm smashed into a rock I try to get down but I'm pushed into it more "snap out of it Sasuke can't u see that Orochimaru is trying to take your body?!" "you think don't know that idiot," I say as I kick him off of me as we are falling I shot a fireball at him that he counters with a waterball as I play into Sasuke's character begin blabbering about revenge and how naruto hasn't felt any pain as I finish speaking I think 'system evolve my Sharingan I'm ending this' I think as my Sharingan grows another tomoe

sasuke has been up to something during those couple of months he has been building EXP through the system by doing tasks I hope u enjoyed this cliff hanger >:)
