" where are we going youthful brother? we have reached the outskirts of village and you still haven't told me anything . " dai said to ren as both of them were walking together in messy clothes after their spar today ..
" relax brother, we have already arrived! " ren replied casually but dai raised an eyebrow because they were standing in a dark alley .
still dai had absolute faith in his youthful brother so he decided to wait patiently. but the next scene left him bewildered as ren took out a token from out of thin air which glowed and then ren pushed him into the wall . dai passed through the wall like water and ren followed his figure walking inside casually . dai even though knew about wonders of fuinjutsu and ninjutsu but he couldn't help but feel surprised as his youthful brother possessed such means with him . he suddenly started feeling a little more proud as his simple brain was incapable of blaming ren for keeping secrets from him ..
of course now both of them were inside the hidden uzumaki secret grounds which was practically ren's personal playground now . it was the first ren brought dai here despite their year long youthful friendship . ren simply had no choice in the matter because here he plans to let dai practice the rakshasa blood body tempering technique in peace. outside the huge chakra fluctuations will definitely alert danzo and hokage which ren absolutely wants to avoid . still ren was feeling a little bad as he had to break his promise with mito to never let anyone else enter these secret grounds even if they are fellow uzumaki . but dai was a true friend who would absolutely keep this secret with him so ren's mood became a little better .
" dai , stop feeling surprised already . here this this a technique that I've brought for you to practice. quickly memorize the right chakra circulation method and let's start .."
dai was confused as his youthful friend handed him an old looking book but he had immecable trust in him so immediately started reading it . but his eyes became moist during reading and finally tears were gushing out uncontrollably after dai finished reading the book . " my youthful friend , I won't ask about how you got this profound technique but are you certain that I can practice it? " dai knew that this technique was way too valuable so even though he knew about his youthful friend's generosity, he still could not help but ask ren this question ..
ren seeing those manly tears also became emotional but he knew that dai would feel indebted to him regardless of any explanation . so ren simply didnt waste any time and kicked dai lightly while controlling his tears from falling down as he was anticipating the fate of his youthful brother changing after practicing the technique . " cut the crap and start circulating your chakra dai . your brother can do anything for you so what does this little technique mean hmphf.." ren took out a huge glass container more than 5 meters long filled with dark red liquid .
this was blood of a S rank beast that ren had purchased through black market with 60 million ryo . this money was practically all his savings from selling the books but ren didnt hesitate using it for the betterment of his youthful friend . the process was easy as the black market had a good system in which the secrecy of client is ensured . only the price of things is usually way more expensive but even so many still buy many ingredients or special things from the black market route. the reason was simple because the things that cannot be acquired from normal route can be easily bought from black market with just 4 or 5 times the normal price .
the blood of a S rank beast is a very precious medicine and research ingredient so the village wont sell it casually to anyone . S rank beasts were too rarely slain and that was the reason . but in the black market one just had to ask if they had the product in stock or issue a job for powerful rogue ninja to acquire the product from somewhere. this black market was a too mysterious organisation as it was spread in the whole world but nobody knew who founded it . the most mysterious fact is that this underground organisation exists from even before the warring period when there were no hidden villages and ninja fought regularly for resources and pride . ren speculates that black zetsu must be behind this as he is the most mysterious and old existence but who cares about the source . ren is completely satisfied with the successful purchase and doesn't give a damn about the method . but he was surprised as the one who introduced the black market executive to him was the manager of publishing company in leaf village. he didnt expect that normal civilian to have ties with such a dark and dangerous organization.
after being scolded by ren , dai decided to fulfill the wish of his youthful friend and immediately started circulating chakra in accotwnce to the path described in the technique without any other thoughts . each ninja knew how to circulate chakra and control the pathway as they have all experienced it after awakening chakra for the first time in their lives . so dai after 3 or 4 seconds went into deep mediation as he was completely focused on circulating his chakra because he had faith that everything else will be perfectly handled by his youthful friend .
ren didnt dissapount dai as he immediately activated his sharingan and confirmed that chakra was circulating at high speeds with no problem . following the manual ren waited till the 50 th complete cycle and started pouring the beast blood slowly from the top of dai's head . magically the blood faded in colour after coming into contact with dai's body fast. ren was satisfied as the blood esence was being properly absorbed into dai's body at a frightening pace so much that it could eat him alive . ren placed his left hand on dai's back and pumped his blue chakra into dai's body without caring about chakra exhaustion at all .
with his sharingan ren confirmed that the foreign dark red cells that were eating away dai's cells calmed down after his chakra was being madly absorbed by them . thus ren increased the speed of pumping his chakra with a smile because his conjecture was right about cells consuming chakra for assimilation in stead of vitality. the whole time ren didnt stop pouring the beast blood gradually from on top of dai's head and it was being absorbed into dai's body at fast pace .
in the end it took more than 13 minutes for the beast blood to run out . dai was still in deep mediation unaware of the fact that his body was producing crackling sounds and his skin color had a red shade to it now . dai's hair changed from black to dark red and grew at a fast pace which could be seen with naked eye. after dai's head hair reached his back in length, the colour changed from red to pitch black and a huge shockwave was produced from dai's body that caused the ground to crack. dai opened his eyes and after clenching his fist for a while flashed a tooth grin at ren who was smiling at the hairy dai .
both of them didnt say a word . ren just nodded his head in satisfaction while dai had become stiff as his tooth grin was frozen and tears were gushing out from both his eyes ...
