rakshasa blood body tempering technique
right now ren was standing inside a small room and the only thing here was scrolls and books that are scatted all over .
this hidden room is the one mito mentioned in her letter to him . so ren didnt waste time to come here as he was sure that power hungry people like danzo must be using his root or subordinates to ransack uzumaki inheritance everywhere. well ren was being paranoid as this training grounds was too well hidden but still he was not wrong to be cautious because according to mito all the information here is too valuable.
what a joke ? this room contains many research materials of tobirama and some secret jutsu that hashirama collected in his life from other places . ren being an earthling knew that possessing treasure is itself a sin as others would gladly stop at nothing to obtain them from you . this information is way more precious than normal treasure too .
ren decided to store all these scrolls and books inside the storage seals on his hands because he will only feel satisfied with so much precaution. on one hand ren was too excited too because this place must have some advanced rank jutsu so ren wont have to go through the trouble by stealing from village or earning merits to exchange them for high rank jutsu . and the most anticipated thing for ren was that the village is very strict with handling forbidden jutsu so it was not certain to obtain them even if you have enough merits . after all , the higher ups would only allow their trusted or brainwashed ninja to practice the forbidden jutsu as they can easily keep an eye on them . ren isn't confident in deceiving the old foxes who have lived a little too long so the anticipation he was feeling was too much right now .
ren decided not to waste time and used shadow clone jutsu . immediately 5 clones appeared after a cloud of smoke and even without getting any orders from original ren they went towards different sections . 6 pair of sharingan were enough for ren to memorize everything here in just about an hour but he decided not to do so .
ren was not much experienced in the knowledge of this world yet and every piece of information here was too advanced for him yet . so he decided to only look for forbidden jutsu or some kind of special techniques right now while stiring rest of the scrolls inside his storage seals for future use .
tobirama must be a neat freak or something as even the room was a mess but it was still easy to find the right techniques because even though looked scattered , all the mitsu were neatly arranged in their respective sections . the section for forbidden jutsu was not present but at the end of the room , where the most small book shelf was located had a small barrier seal guarding it . this of course could only mean that there something special was sealed so ren dispelled the shadow clones after they had finished storing every piece of information in the room except that particular small book shelf .
when ren placed a hand on the barrier which was deep yellow in colour , he just wanted to check it but surprisingly his hand easily went through without any obstruction . ren them remembered that mito must have done something so that easily gain access to the books and his eyes became a little moist.
ren held a book that he randomly took out from the thick books in the shelf . the cover had become pale yellow which indicated that the text must have been written long ago . ren's curiosity couldn't be contained anymore so he flipped open the old book while activating his sharingan ( 3 tomoe each ).
the book contained more than 70 pages which contained various weird illustrations and knowledge but ren was left bewildered by the content. mito had hammered the ancient language inside his head so even though all the content was written in ancient language ren read it easily . he was left speechless because this was actually a technique from sage lands . ren knew from anime about sage lands like frog mountain and slug cave so he also knew that their techniques are the inheritance . the first random book turned out to be so precious !
the technique was only one named rakshasa blood body tempering technique . this technique was created by an old demon who lived in the slug forest with many other species too . the demons had a peculiar way to train as they didnt use any chakra . they just bathed in the blood of enemy bodies and their special condition becomes stronger by absorbing the blood esence .
the old sage rakshasa was the first sage from the demon clan and he searched their condition to create this technique which can be practiced by their contractors . demons may be physically strong but they had to pay a price of lifespan and sanity the more enemies blood they absorb . this technique only had simple method to run chakra while bathing in blood of high rank beasts to forcefully increase the body consttuion while the chakra network wont be affected. this was different from transforming bloodline as ren also recieve benefits of huge chakra pools after absorbing strong bloodlines like uchiha . so this technique was useless for ren as he already had huge body potential and it will increase much more with him absorbing other bloodlines like senju and uzumaki . besides he doesn't want to pay the price of lifespan and sanity which is more than 20 times more for human practitioners of this technique according to the scroll .
this technique may seem useless but it was actually god sent for ren . simply because he was planning to use similar methods to increase the body strenght of dai . this technique was too suitable for dai as the energy that transforms the chakra network will also be used to temper body which means greater strenght . if dai practiced this technique then he wont have any need to use 8 gates technique which harms his body . besides dai's body when reached 3 rd level of this technique will allow him to use 7 gates freely because his bones and cells will become too strong by then . dai's chakra amount wont be amplified by this technique at all therefore the chaotic chakra will also not increase when using 8 gates technique. this technique is simply made for taijutsu idiot like dai who have less potential...
