Two years and Uchiha massacre

The next morning I wake up by a beautiful smell. For one or two seconds I try to figure out what's happening I am rescued by a door knocking sound. Until the Uzumaki compound finished Karin and Yua stay with me so smell is probably breakfast and the one who knock my door will be Karin most likely to call me for breakfast. After figuring out what is happening I get out of my bed, [ and start to wait for fucking lessons to start while I am writing these lines at 8 a.m. :( ] open the door, said ''Good morning'' to Karin. I swear she starts to shine after that. It seems my days become more colorful from now on...

I start to train Karin after breakfast about the basics of chakra control and show her leaf control technique, then tasked her to master it. Now I must start my training too. First, I am starting with Minato and Kushina's scrolls. There are notes about Rasengan and its variations, some speculations on Rasengan with nature transform like Rasenshuriken, flying rajin Minato version and its variations too with some notes about natural energy, senjutsu chakra and sage mode in Minato's scroll while reaper death seal, eight trigrams seal, contract seal, four symbols seal, Torii seal, chakra draining seal which used by Kabuto for Akno's cursed seal and some more seals with another scroll abut adamantine chains. Kushina's scroll is a little different from the one I found inside of the Uzumaki mask temple. Too bad scrolls don't contain anything about Kage-bunshin no jutsu or Edo Tensei because these are the village techniques and forbidden to transform others. Well nearly all of them above my level for now but they will be pretty useful in future also some of the seals in Kushina's scroll not so hard to learn so I can learn them now unlike most of the scroll's contents.

-Two months later-

The summer break ended and thanks to my training Karin attend classes the same year as me. When she introduces herself everybody surprised especially my gang because they know there is no other Uzumaki in Konoha other than me. She and Hinata quickly befriend each other and she become a new part of my gang. After lessons end, we see a boy in front of academia entrance with really weird outlook but the main thing got my interest is not the kids looking or kids eyebrows (They are the second most interesting thing), most interesting thing about this kid is his identity and the idea he gives me just with his appearance. That kid is Bru- *chough, chough* I mean Rock Lee and I don't know why but when I see him I think '' I must open a gym for shinobis and academia student'' at first it seems like non-necessary because shinobi already have the training grounds they don't have efficient training tools like we have in the modern world while they have special exercises for that I am sure new types of equipment will interest them and they will be effective too. I can alter the weight of equipment with seals just like Rock Lee's epic weights in the manga! This also gives me some ideas about creating weapons but I focus on this later. I will build the Gym near the Uzumaki compound. This can attract more people near Uzumaki compound with the other works of mine the land around Uzumaki compound increase in value. I create the second trade street in Konoha...

-Two years later-

The gym became more popular than I wait. Mostly thank to Maito Guy its name spread fast and lots of shinobi found it effective. I set monthly price for membership, then call it %20 discounted price for jonnins and %15 discount for chunnin, %10 for gennin, %5 for the academic students. I also talk some retired jonnins and employe some of them to give instructions to the gym members and polish my sealing skills and imagination while produce and adapt modern equipments to shinobi word. These things aside tomorrow Sasuke's 8 birthday also the day of the Uchiha massacre and I plan to get some samples to understand how the Sharingan works. I am not interested in implant Sharingan to myself, no thanks I don't need to gain power from the loss of people I love and go crazy because of hatred or to gain more power. But I really interested in how to base Sharingan works and its enhanced perception with the ability to read the opponent's movements. Maybe I can create some kind of jutsu to achieve the same kind of effect. Also, the fact we don't see Fugaku Uchiha's Mangekyo Sharingan in no one's possession leads me to think he doesn't have Mangekyo or no one loot his corpse. So if I have the opportunity I get his corpse right after Itachi leaves there. Also I will collect some other Uchiha corpse to on the way. I am not juts go and take their eyes, I will store their whole corpses into scrolls because I want to see all difference of Uchihas who have one tome, two tomes, three tomes, Mangekyo and no Sharingan from a normal person. I don't even thin think about stopping the Uchiha massacre because of three facts:

1- I can't stop Obito and Danzo

2- There is nothing I can gain from it. It will harm me actually.

3- I want to search and learn about Sharingan too. Both as a doctor, a shinobi and a Naruto fan this is a perfect opportunity.

Now I must do some preparations before taking action...

-Next days night, Uchiha clan compound-

I am walking on the walls of buildings inside the Uchiha compound as a Gekko while waiting for Itachi to finish his job. Thanks to chakra surpassing seal I learn from one of the scrolls I found inside of Uzumaki mask temple I don't worry about someone will see my chakra with their Sharingan as long as I am not using a technique needs to send chakra outside of my body. And I use half fingered gloves (I am not sure but they call it mitt if I am not wrong. The bicycle rider gloves will be a good example) with enclosing seal on palms so I can store the bodies without break chakra surpassing seal because it is cover my clothes too. Oh, he finished the ones on the street and goes inside a bigger house than others. Probably his own house while waiting for Sasuke I am starting to collect some of the corpses two non-Sharingan, three one tome, three two tomes, and three which have three tomes Sharingan. Now time to wait for Sasuke... Finally, he has come. He sure put all his effort into shuriken training. And 1, 2, 3 screams!

-Ahhh!

Yep. I have perfect timing. He runs his house, another scream, five minutes of silence, Itachi comes out, Sauke comes out try to attack Itachi with shuriken and that's my time. I am going inside their house. There is Fugaku and Mikoto Uchiha's bodies.

<Enclosing seal>

Ta-dah! I get everything I want. I will seal them in scrolls and hide it until I create '' That technique''. Now time to go home...
