ren and dai were both chatting happily in the training grounds which only these two use and dont know why but nobody comes here.
after mastering soru now only repeated practice or use of the technique will bring some insights and the best way to increase the proficiency is of course increasing body strenght . this technique has nothing to do with chakra after all .
it's a martial art not a taijutsu technique and a superhuman one at that . in this world of chakra maybe there isn't anyone else who practice pure body martial arts like ren and dai . after all they can reinforce their bodies with chakra which is way easier than training body using extreme and even brutal methods.
the talented ones who have better chakra control or some kind of special bloodline use the taijutsu of tsunade , uchiha taijutsu etc . tsunade is all about chakra control and uchiha all about sharingan so you can guess everything else . dai has really small chakra coils barely any thicker than a civilian and his limits of chakra reserves are just low . so he cant use much chakra in combat much less techniques that require extreme chakra control . so pure body martial arts are the best suited to him as he can overcome the painful training with enough youth .
martial arts are all about control and compressing the strenght to use more powerful techniques . soru is the great example of that as it uses control and compressing strenght at the bottom of feet for instant explosive speed . the better control over strenght , the better the effects of technique. no chakra amount or control nonsense so it's the best for simpletons .
the punches that both dai and ren were using during their spar could be also called pseudo martial arts . simply because the technique can be improved much further and has no particular name . the only difference from normal punches and kicks is penetration power and shockwaves. unlike ren , dai has too much talent in the martial arts field so ren plans to teach him more techniques that are in his mind like kugi punch, happo navy shock arts etc and of course other rokushiki . well not teaching as ren himself doesn't know the principles behind the techniques only raw understanding. but with dai's prservance and talent ren is confident that dai can recreate the techniques on his own and maybe come up with his own techniques too ..
as for ren himself ? he plans to not focus much on body arts because he plans to walk the path of swordsman like Dracule mohawk from one piece. the reason ? simple because it's cool and ren discoverd that his comprehension ability for sword intent is much greater than other body arts .
like body arts , swordsmanship is also an art in which one passes his strenght and intent to the sword for attacks. ren has the basic requirement for strenght and its control too so two days before when he was practicing with a normal steel sword , ren guided all the power of his body in the sword for one attack. the result was devastating and awe awespiring . devastating because the ground in front of him was cut in half and the cut was more than 5 meters deep .
ren himself fell on the ground due to exhaustion but he could only laugh madly after watching his deed . ren was a huge fan of kenjutsu or swordsmanship but he didnt even have a speck of basic comprehension as he never had the opportunity to learn. but all of that was bypassed as ren's full strength strike that was only out of desperation turned out to be a huge more than 17 meters long flush sword slash like bad boys from one piece .
why wont he laugh madly at this truly coincidental and amazing actions? his dream was in front of him and now ren had the vague idea how to train swordsmanship too.
one's bloodline in this world has a limit to maximum chakra reserves and body potential one can reach in a lifetime through training. of course after the limit one can train more like with medicine etc but the improvement can be said minimal. but for dai and ren who practices pure body martial arts it was different. of course they both use chakra to reinforce their bodies during training as they would be idiots if they dont use this magical power as it makes things much easier .
ren has pure bloodline and concentrated uchiha at that so his body potential is great but dai is different. ren after absorbing and cleansing bloodlines , can roughly gauge the limits of one's bloodline with his passive sensory perception . ren of course for planning a training plan for his best friend checked dai's potential but the result really made ren realise that the world is unfair .
dai's chakra network is too thin and even if he trains chakra till old age , with his talent the chakra reserves wont surpass low chunin level . this discovery made ren feel bad for his friend as he had seen dai's passion for training and improvement. so dai has no choice except to train his body limits with extreme training constantly to break his limits for further body strenght . ren was truly impressed with his dandy friend who chose the brutal path of sole taijutsu due to his limited talent .
but it's not like dai cannot improve his physical strenght without chakra fast at all . there are many methods like medicine , genetics etc but the most sure and fast method is simple . it's to eat the meat of strong chakra bests . strong chakra bests have some natural chakra in their bodies which they unconsciously or consciously absorb . so their bloodline has much potential and superior strenght of course rare special abilities too . dai can eat the meat which will transform his own bloodline much faster because dai's bloodline is too weak . so the strenght dai will gain will be much better than stronger bloodline users too .
of course dai wont improve much on his own but ren can help him . ren can help dai cleanse his bloodline after eating meat by sending chakra directly into dai's body . this method would not be painful as the stronger meat of chakra beast will actually help dai by absorbing most of the foreign chakra thus breaking down faster and getting absorbed more easily. the process of bloodline cleansing is very painful so much that even dai with his extreme presence may instantly pass out from pain . it's so because all the cells will reject the foreign chakra therefore the impurities or toxins will be excreted as too slow pace . it may even take days but still the bloodline wont be cleansed even by 20 percent . this is the reality therefore only sometimes the clan relatives baptize their newborns with their chakra and nobody else attempts bloodline cleansing .
the clan members have similar bloodlines so this method is occasional helpful but ren has absolutely no bloodline connection with dai . thus the foreign chakra rejection will be much much greater too . ren if has more chakra control than kage level the maybe he could ease the rejection as it will be easier to transform his chakra to close to the properties of dai 's chakra. this method is actually common in medical ninjutsu but they only heal injuries not cleanse bloodlines after all . anyway, ren can help dai's body become much stronger by cleansing his bloodline and transforming it with combing with strong chakra beasts. anyone else like even madara wont have enough chakra amount for this but ren has infinite of it after all hehe..
