On the next Class i brought chakra pills and spent the whole class fixing mistakes of the kids using the jutsu,
The only ones that surprised me are Menma, Sasuke and Hinata,
Menma was in pain when using the jutsu, because of the seal, that constantly fills Naruto with Kurama's Chakra, the jutsu nature is use your chakra to purify your body, mind and soul like if it was a cultivation technique, thus purification from Bijuu chakra is painful, but will bring more benefits, because of this, his body is slowly getting more and more perfect to hold and control Bijuu Chakra, making him the perfect Jinchuriki, that would normally be tolerable but then we have Asura's Chakra into the mix, it is also refining itself and Naruto's body, but also is getting expelled (because is a parasite that should be expelled) when he's finally done with it he will lose that personality that made Naruto the clown, those moments that He and Hashirama shared were he was very clever one moment and an idiot the next, but he will get, all of Asura's Talents, including Yin-Yang affinity, a complete talent for Senjutsu, and the Chakra to become a Six path Sage (thus gaining mokuton) , his character as A Leader will shine, and talent for Ninshu (and thus Ninjutsu) will be all time high… go die protagonist plot armor
Basically he's making the Uzumaki bloodline more op that already is, and the only catch it a little pain for a couple of hours a day for 1 to 2 years
Sasuke is the same but at the same time the Opposite, he's not gaining bodily talents but mental ones, he's in pain just from expelling Indra's Chakra (which is probably the main reason of the 'Curse of Hatred' and the moodiness from the Uchiha clan) he's gaining a lot, his brain is improving, making him invulnerable to the side effects of the Mangekyo Sharingan, his eyes won't need trauma to be unlocked, his determination and training will be all he need (even for the Mangekyo) his mind is going to get faster and his Genjutsu will be scary, he's almost to the Kurama Clan level with this new level of spiritual level but obviously he won't be able to have the Rinnegan without a Senju's or Uzumaki's Chakra another fucking plot armor, because this is also improving the Uchiha Bloodline to a stupid level, forget Sarada, i doubt that even after 1000 of generations other Uchiha will need Glasses, his vision and his descendants will always have 20/20 vision…
Hinata is getting two reactions one From the Seal, and other from her own Chakra, first
The seal (obviously the "master version of the Cage Seal) is only for destroying bodies of the Main Branch after death and to activate the Cage bird seal of the secondary branch…
This seal was badly modified from one that was a gift from the Uzumaki, this seal has the consequences of wanting to activate it just cause and cause pain to the secondary branch, if you don't, it will slowly mess with you till you have no will, no dreams, no objetives, so you either are a sadist or weak minded, that's probably the reason, all the Hyuuga rather stay copying each other till the only acceptable thing is traditions, like only using the Taijutsu,etc…
The jutsu is slowly but surely getting rid of the side effects so she won't be shy (probably something that happens in the road of ninja Au, and Minato got rid of the bird cage seal, so she didn't suffer consequences of it)
The other side effects also is improving it bloodline, not because of Otsutsuki Chakra like Naruto or Sasuke but actually because of the Lack of it, The Byakugan, the Chakra and the Jutsu, know that the bloodline is "incomplete" without Otsutsuki Chakra, so is trying to improve itself to become "complete" but obviously Hinata doesn't have Otsutsuki Chakra to improve itself to Tenseigan, so the Chakra is searching in Nature Chakra, what it lacks, which is actually quite advantageous, because she's absorbing natural chakra not to become a sage but to improve her bloodline, so it will probably destroy the weakness of her Byakugan, and develop a lot of more power to see more spectrums things like, maybe she will develop X-ray vision, or magnetic spectrum, violet ray spectrum, etc… and if she finds even a little bit of Otsutsuki Chakra, she will unlock the Tenseigan, the Gravity control, Truth seeking balls, the Yin-Yang affinity and who knows what else…
These 3 little geniuses… i want to eat them… but it doesn't matter, i will wait, till they are at their best then "ask" for blood to improve myself, obviously i can't wait for them to expelled their Otsutsuki Chakra so i took samples of Asura's and Indra's Chakra but they will be better than their ancestors so i can't wait
As a side effect, i guess Naruto and Sasuke aren't destined to fight each other anymore… huh
Anyway the first year was a lot of theories and histories to make the children learn, and i saw how my jutsu was changing them, they weren't changing a lot but, doubts were harder and harder to appear on their minds, they were getting more and more confident, unconsciously of course, things that bothered them we less and less, i think even the jutsu was eliminating genetic problems like the Nara's Laziness, Inuzuka's more Animal tendencies etc…
The second year was a little more practical, with things like (go and buy ingredients under a henge) and things like that, and finally Halfway into the second year, the Uchiha Masacre Happened, lucky for Sasuke, he didn't go home early like in Canon, but he made his Mission to interrogate (and kill if necessary) his brother to know why he killed the Uchiha this obviously gave him a huge desire to become better so he started being his best on all classes (including mine, to my delight)
