"System, set the following simulation prompt: 'In my next simulation, I want to join the academy and become a taijutsu and bo staff master, focusing on learning all taijutsu and bo staff styles I could find, then create my own style. Also I want to focus on proper nutrition for working out.'"
[Ding! Prompt set.]
"Ok system, start simulation"
[Ding! Starting simulation. Simulation performed.]
A small ring appeared in my hand. Inside it there was a lot of food with notes next to each food. There were also some books, a booklet and a scroll. Just like last time, I moved everything to my main ring and "erased" he fuuinjutsu from the new one. Then I removed the Mindscape Library Upgrade scroll and upgraded my mindscape. The next thing I did was reading the tl;dr version of the diaries.
During this simulation I had 2 months until the next enrollment period. I asked my mother to hire a taijutsu and bo staff instructor for me. She did hire a person that was proficient with both, also bought me a small bo staff. I would spend 2 hours each day with my new tutor practicing taijutsu and bo staff. Unfortunately, I had to turn off my Hidden Yin Seal's healing factor when practicing with my instructor. If my wounds would heal instantly, that would raise suspicions. Also the style we were practicing was the academy style.
After 2 months, I started the academy, and my tutoring sessions moved to the evening. My mother would heal every injury I had after the training, and then I could use my Hidden Yin Seal for healing. With it, I could run for a very long time without getting tired, and my muscles would heal instantly, eliminating any risks regarding too much workout. Most of the problems regarding nutrition were also negated my chakra and by my healing factor, fut I taught I'd better be safe than sorry. I read anything I could find inside the library regarding nutrition. I also studied my medical texts.
At 7 years old, I asked my mother if she knew any other taijutsu styles. She did know 2 others, the Leaf Taijutsu and the Red Panda Kata, which was my father's fighting style. He signed a contract with the red pandas and learned their taijutsu style. The Leaf Taijutsu was a variant of the Academy Taijutsu, with some things added to it and a few variations. My mother taught that I had too little experience with the Academy Taijutsu to start learning the Leaf Taijutsu, so she started teaching me the Red Panda Kata.
At 8 years old, I started wearing leg weights to increase my speed. Due to my healing, there wasn't any problem with this. I did hide this fact from my mother and anyone else though. At 9, my mother started teaching me the Leaf Taijutsu. My instructor also started teaching me a new taijtsu style, the Feather Fist. I was the best of my year in the academy when it came to taijutsu. I also started using shadow clones in my training. I would create multiple clones and restrict them to a specific style. I would do the same inside my mindscape, where I would create one clone that wouldn't dispel after one hit, and we would restrict ourselves to one or two fighting styles during our spars. This way I managed to train all my taijutsu styles.
At 10 years old, my mother hired a different bo staff instructor. His fighting style with the staff was a little different then the previous one, and he knew 2 different taijutsu styles I didn't already know, the Heavy Fist and the Dancing Fist. He also knew the Drunken Fist, but I was too young to learn that one. The new tutor started by teaching me the Dancing Fist katas. At 11, he started teaching me the Heavy Fist. This fighting style didn't suit me, I liked relying more on speed then on strength.
At 12 and a half, I graduated from the academy. My team easily passed the jonin test. We were all focused on taijutsu, and our sensei was chosen based on this. My mother also hired a new tutor. This time it was Ebisu. He turned out to be an amazing teacher. He knew the basics of 6 taijutsu styles. I guess the fact that he was on Gai's team helped with that. He was also a very good teacher, though a bit expensive. I had to put all my mission money into paying for Ebisu's training, since my mother couldn't afford to hire him with only her salary. My jonin sensei also knew over 8 taijutsu styles.
At 14, we participated in the chunin exam. Only I managed to get promoted to chunin. Six months later, my teammates were promoted as well. At this point I knew 11 taijutsu styles. With my mental enhancements, they were pretty easy to learn. I was ready to start learning on my own as well. I already had access to every scroll in the library. I also watched a lot of kids in the academy perform their katas, or sparring. This included the Gentle Fist and the Uchiha Taijutsu Style. They required their specific dojutsu to be effective, but with my Pseudobyakugan and mental enhancements, I could use both of them effectively.
At 15, during an intense training session, I accidentally opened the first gate. I create a shadow clone to use the Pseudobyakugan to check out how the gate works and how it looked while opened compared to it being closed. At 15 and a half, I managed to open and close the first gate whenever I wanted. At 16, I managed to open the second gate. I didn't have any training with the gates and had to figure everything out on my own. The mental enhancements and the Pseudobyakugan helped a lot though. At 16 and a half I was already an expert with the first 2 gates.
At 17, the day of the attack came. I stayed in a remote area of the village next to a shelter as usual. I helped the civilians to the shelter, and when the enemy ninja came, I was ready for them. I managed to defeat 5 enemy ninja. After everything settled down, I found a jonin as in my previous simulations. He sent a chunin to help me with the captured enemy nin. Then I went home and wrote my report. I spent the following days helping with the repairs.
At 18, I managed to open my 3rd gate. My healing factor would heal all the wounds created by the gate instantly, strengthening it. I became proficient with the 3rd gate in just 2 months. Me and my teammates also kept taking missions. The highest was a B-rank mission. I also kept practicing all the taijutsu styles I had access to. At 19, I managed to close a tenketsu using the Gentle Fist. Then, with the help of shadow clones and mental enhancement, I managed to master the technique. At 20, I already mastered the basics of the Gentle Fist. I didn't have access to the more complicated techniques of the Hyuuga.
On the day of Pain's attack, I hid on the outskirts of the village, and ran away in the confusion. I then changed my haircut, grew a beard, got contacts and made sure to not leave a trail. Then I went to Wave Country and bought myself a house. While there, I studied my Rejuvenation Jutsu. I already had some medical knowledge, having studied it to make sure I didn't damage my body. In 5 years I mastered my Rejuvenation Jutsu and turned myself into a 12 year old. Now no one would be able to recognize me. I then went and joined a temple that was specialized in taijutsu.
At 28 years old, I managed to master 4 new taijutsu styles and 1 new bo staff style. I also managed to open my 4th gate. I then left the temple and went to a different one. I kept doing this until my real age was 60. During the years of training, I managed to master the first 7 gates. The chakra consumption was huge, not only did I have to spend more and more chakra with each gate, but I also had to use chakra to heal the damage done by the gates on top of that. The results were amazing though.
I also had a plan for a taijutsu style specifically made for me. So I left to a secluded place for the next 2 years and created my own taijutsu and bo staff styles. Then I rejuvenated my self to a 20 year old body and started going to temples in different countries to perfect my fighting style. After another 10 years, I felt like my fighting style was complete. I called it the Basic Shadow Style. I then bought another house and spent the next 10 years practicing my shadow manipulation and senjutsu. I was 82 at this point.
After mastering shadow manipulation, I managed to incorporate it into my fighting style, creating a nintaijutsu I called the Advanced Shadow Style. It incorporated high speed, shadow form, shadow manipulation, shadow possession and shadow teleportation. Adding senjutsu mode to that took it to another level. I managed to create Senjutsu Shadow Style with it. If I added the gates on top of that, I was pretty much unstoppable. The nice part was that the gates didn't do much damage when I was in shadow form, since my body was made of shadow, making the gates perfect for me. My body also adapted to the gates, and I didn't take much damage anymore to begin with.
I spent the next 2 decades traveling the world and learning any taijutsu style I could find, while also making small tweaks to my own style if I found any room for improvement. The last 3 years I spent creating a Mindscape Library Upgrade with all the taijutsu styles, memories of all the katas, and also a lot of chakra stored inside in case my real self needed to talk to my simulated self. Taijutsu was easiest to learn with a master that could point out your mistakes after all.
After I finished reading the tl;dr booklet, I became excited. I entered the mindscape and went to the "Taijutsu Master" section of the library, where the chakra of my simulated self was stored. Just like Minato appeared inside Naruto's mindscape, an older version of myself appeared and said:
"Ready to start training?"
I spent the next 2 hours training the Basic Shadow Taijutsu. I could use the "Taijutsu Master" for a limited period of time, so I would have to do most of the training by myself, and check in from time to time to see if my form was correct or to get tips on what I could improve. This is how I spent the next 30 days, doing a lot of training. I was very excited about my next simulation, it was time to put everything together, a simulation in which I would try to learn everything. When the 30th day was up, the long awaited sound finally came:
[Ding! Host has received 1 simulation opportunity. Next simulation opportunity will be received in 30 days.]
