28 Ramblings of an old man

After accepting every condition of old man Chen, Rei became his last pupil and swore not to take more in the future. After the war where his previous student died he swore to himself never to teach anyone again but this time Chen made an exception because of the potential he saw in Rei being able to use C-rank ninjutsu and D-rank genjutsu is an amazing feat for a child at Rei's age.

Chen might not be able to teach Rei anything about Ninjutsu or Genjutsu but for those things to be effectively use, fighting with weapons or barehanded must be added into the mix besides the child himself would like to specialize in taijutsu because of his average chakra reserves.

Chen: Rei what are those physical training methods you were using they are quite new to me.

Rei's rehearse answer from the moment he started using his previous life experience to develop his training method to develop more pink muscles in his body now comes into play. Rei delivers his speech and acting like someone who's veteran in screen play.

Rei: My father taught me the almost everything I know right now master. But I thought that I should train every muscle in my body and build stronger ones. So, I was experimenting on every movement to test which muscles are being use and came up with this physical training.

Chen: This kid, you are not just a genius of two disciplines of a ninja but three. I can see that the training method you are using right now is extremely effective and the muscles it could possibly develop are much stronger than the usual ones. Continue doing that aside from that you will start sparing with me so that we could correct your techniques and bad habits. And kid being a genius does not mean anything if you don't mature to your maximum potential and to reach that you'll have to train, train like your life depends on each passing second of your training doing your best even in simplest things.

Rei: Yes, master!

Though Chen has no idea about muscles and medicine his mastery of taijutsu made him a good judge of the body and the muscles they have. This came in handy throughout his life since judging the muscles of a person would make you understand what kind of movements they use the most. Sometimes he'll be able to deduce the kind of technique or movement they frequently use to end their enemies from their muscle development, he is quite helpless though if they are ninjutsu or genjutsu specialist.

Rei knew how important training was and the genius title he is getting right now is only temporary since hard work is the reason that he could reach this level at just five years old and soon to turn six, his mental maturity, and his memories from his previous life takes a huge part in all of that since the training methods and fortitude to push through his training are maybe the "cheats" he brought along, aside from the chakra talent he was bestowed upon Reincarnating.

Once he gets cocky and laze around even for a bit Naruto's generation might just surpass him like an insignificant character specially when the three from team seven gets their respective sannin masters. After the time skip everyone just became freakishly strong in their own ways.

Chen: In my life as a shinobi I was known widely as a taijutsu master even the current third hokage wouldn't dare fight me in close combat. That hiruzen has to resort to using his mastery of the five basic nature transformations to defeat me. That cheating man would even use his summoning creature monkey king as precaution when I get close to him. Right now, though we just turned into two old man. I quite pity him since he has to take charge as a hokage again those good for nothing student of his going off on their own. that jiraiya should've become the hokage instead after the fourth's death a pity if he was here when the incident of the kyubi happened things would've been different.

Rei heard his master's rambling while training it is true though that jiraiya has his short-comings but that guy is trully one of the strongest ninja of hidden leaf and he could easily rank in the top ten even counting those who are already dead from other hidden villages. Jiraiya is strong enough to fight against pain destroying three of the six without even knowing any information and what he learned ultimately lead to pain's defeat.

Hearing about jiraiya made Rei wonder if he could enter sage mode but remembering how much chakra potential he has that's definitely impossible unless he does something crazy like incorporating hashirama cells into his body.

Rei: Master what should I do... Should I start training with weights?

Chen: That's a good idea to strengthen your body so that we can start to train on my taijutsu techniques, don't listen to those people that said you're still growing and shouldn't use weights it wouldn't affect your physical growth at all just train your chakra and eat well. I got something better than weights though, throughout my life I've become friends with a lot of shinobi this bracer makes your body feel twice the weight. Adjusting the knob in the middle would re-calibrate the fuinjutsu to make you feel more weight or lighter.

Rei was quite feed up with his master's ramblings but he has to listen since who knows when the man will say something really important. Besides he has the patience of a middle-age man if he was any other kid he would probably rant all day on why's his master is talking about a lot of information he doesn't really need.

Rei was also intrigued by the bracer his master took out he knew how complicated the object was since the fuinjutsu actually increases the gravity his body feels and it is so much better than having the ultra-heavy weights rock lee wore and dropped during the chunin exams.

Rei: that's amazing master! where did you get it?

Chen: I think I got it from an uzumaki, an old friend. But given how old I am who knows there are things that are hard to remember boy. this thing is also the reason how I got to reach my peak back then!

Rei: You are giving it to me now?

Chen: I have no more use for it now, my body has been declining for a long time now. Besides its training use you can actually use it to deflect things child don't worry about it breaking, I once hit it with my strongest technique it didn't even left a scratch. But still don't use it to block weapon with chakra flow on its own you better Reinforce it with your own.

Rei: Strongest technique?

Chen: Hahaha! finally I was able to see a childlike reaction from you... you'll learn it my strongest technique is leaf dragon god. By the way you didn't forget my Rice Balls, did you?

Rei was about to be impress by his master since he has something as amazing as an item that actually lets the body of the user feel a different level of gravity. But suddenly asking about the Rice Balls took away all that amazement, he brought it anyway so there's no problem.

Rei then sort of wondered why extremely strong ninjas have weird quirks jiraiya was a pervert enough to be called by Naruto as a pervert sage, Tsunade was a gambling addict, Orochimaru was searching to be immortal and what's with the snake like tongue, there was kakashi who was sort of a pervert as well since he reads jiraiya's book... he might just be always late because of that book, there's guy no need for explanation right, and the third hokage who loves to spy on people with that orb seriously he is like a stalker. Rei thinks hard on what would happen if he gets strong like them would he have a weird quirk as well.

Guess things would be fair now Naruto would have a pervert teacher while he has a gluton for rice ball teacher.

The training with Chen was really effective, Rei already knew that he was a good teacher since he was able to make someone a ninja solely with taijutsu but experiencing it first hand is something else. Rei's master was able to notice the bad habits he makes either when defending or attacking which quickly corrected by Chen. Sparring was always their method of training since Chen said it is better to experience it first then I'll explain later so you could understand but don't adapt this method when fighting real battles, you have to end it as fast as you could if there's an opening with your taijutsu and only use the other two disciplines if there's no way to solve it with taijutsu.

Chen's expertise didn't just end with his barehanded fighting method he taught Rei how to be able to fully control his body and also incorporate weapon use in the martial arts he was teaching since he realize that the kid was well trained in bukijutsu and it would be a waste to stop training it.

Rei was making great progress under his master but he worried for Naruto since they won't be able to train as much and thought he would slack but Naruto didn't and actually hangout and train with Seiho forcing his best friend to endure the same amount of training Naruto always do.

At night though before dinner Naruto comes by to spar with Rei since he says he hasn't had enough training yet forcing Rei to train with him with his body crying from pain but sparring actually made him much more skilled since he has to fight with limited movements.

Meanwhile at the academy during their break.

Seiho: What's happening Rei you doing some secret training?

Rei: Yeah, sort of.

Naruto: Really, what is it?

Rei: Naruto, it wouldn't be secret if you know now right?

Naruto & Seiho: Come on now Rei! -eyes shinning

Rei: I'm just training with much more intensity that's why I look so battered when Naruto comes over before dinner to spar with me.

Seiho: What he still comes to spar with you?

Seiho was shocked by how much training Naruto gets from the both of them since he is already spent after training with Naruto... just how much stamina their runt friend has he seems to be unbeatable in terms of that.

Naruto: Yeah, I thought I was going to win against Rei since he looked really tired but I still lost in the end.

Seiho: Just how good are you going to be.

Rei: I don't know... never plan on stopping though you guys should too since we're going to be ninjas its going to be better if we're stronger right.

Seiho: I'll have a surprise for you this term end better be ready.

Naruto: Hahaha! this time you guys will see what I'm made of!

Rei: yeah but we better prepare for the term end matches right.
