It had been a few Months since Sasuke had joined Orochimaru .
Training with Orochimaru was harder than any training he had ever done alone, not that Sasuke had expected otherwise. Once his wounds had healed enough that Sasuke could move through Kata's again without injuring himself further.
Orochimaru had thrown him into a rigorous training regime. He was quite sure that a lot of his methods bordered on the illegal for anyone who wasn't already a Jonin, if this had been any ordinary village. But this was not an ordinary village, so that was moot point brought up from an exhausted mind. So for the most part a lot of his time for the first few months after switching to this new base had been training till he dropped, pushing himself further than he thought possible, and after eating more or less collapsing onto his bed in utter exhaustion, only to do it all over again.
Within the first few weeks of joining Orochimaru, Sasuke had already been given the Snake Contract and he had already gone to the Ryuchi Cave and passed the White Snake Sage's Test to learn Sage Mode but there was one problem. Sasuke's body was not strong enough yet to learn Sage Mode mainly because he lacked the Chakra Reserves needed, the reason why its so rare that People Know Sage Mode is because you need a Summoning Contract to learn it and even then not anyone can just learn it a huge chakra reserve is needed to learn sage mode and Sasuke didn't currently have that.
Originally Sasuke planned to first learn sage mode and then inject his body with Hashirama cells since the reason Orochimaru couldn't learn Sage Mode was because of all the experiments he did with his body and Sasuke originally didn't want to do the same and take a huge risk.
But now because of the circumstances he is willing to take the risk and even if he cant use sage Mode after getting Hashirama Cells its fine since the Hashirama Cells is a big boost anyway since that would allow him to use Wood Style, give him a Regenerative Ability and also increase his all around strength by a lot.

"Orochimaru-sama isn't there too much of a risk in implanting Sasuke with Hashirama Cells since we cant be sure that he will survive and his body is what your investing so much resources in is it really worth taking this risk?" Kabuto asked
"Kukuku if you asked me this question a few years ago i would have not taken the risk but now its fine since i know for sure Sasuke-Kun will survive, in these past few years i have been able to fully study the Hashirama Cells and know how it works, Normally as soon as the Cells are Implanted into someone they try and take over their body and usually the Chakra of all of my experiments are too weak and they cant fight back but with Sasuke that's a different matter all along, there are only 2 People i have ever met whose chakra has been as Strong as Sasuke thats Hashirama Senju and the Nine Tails Jinchuriki Naruto Uzumaki, the First Hokage was hailed as the God of Shinobi so this is not surprising that his Chakra is so strong and Naruto is the Jinchuriki of the Nine Tails so he isn't a surprise either and the fact that Sasuke is able to match that is a huge thing and we are only implanting a few cells of the First Hokage anyway its not like we are implanting everything we have so im confident that Sasuke will be fine"
"Anyway all the procedures for the Cell Transplant are done now summon Sasuke"
"yes Lord Orochimaru"
-------------
"Alright Sasuke-Kun lay down on that bed and we can start the Procedure" Orochimaru said to me
I wasn't really scared since i was confident that i wont die and in the Anime Sasuke did get Hashirama Cells implanted into him although he was near death so i was confident i would live and i know that Orochimaru would not risk doing this if he felt i could die since i was the one who he wanted as his vessel.
Orochimaru then started to implant the Hashirama Cells into me but i was a bit confused since i expected him to knock me out when doing this.
"You wont knock me out?"
"No after the Transfer is done the Hashirama Cells will try and take over your body but you will have to use your chakra and suppress the Hashirama Cells and after some time it should get used to your body and then you dont need to suppress it or anything but till the Cells get familiar with your body you will have to use a part of your chakra to suppress them and it should take about 5-7 Days for the Cells to get used to your Body"
"Alright"
After a few more seconds i could feel A very Strong Chakra Enter my Body and i could tell it was trying to take over my body but since it was only a small part of it i was easily able to suppress it with my chakra.
"You should be able to feel the Chakra now, make sure to suppress it and dont let it take over your body"
"I already did that"
Just as i said that there a look of shock in Orochimaru's Face for a second.
'I knew he will not be taken over but to be able to suppress it this quickly this kid truly is special'
"Alright well are you able to keep the Cells under control?"
"Yes i have perfect control over the cells, i could suppress them easily, even though the Strength of the Chakra is Strong the amount of Chakra in the Cells are less so not hard at all"
"I see, well for Tenzo only this was the amount i injected and it was hard for him to control it but it looks like its easier for you, would you like me to inject more?, the More you inject the stronger the Cells will become and the more powerful you will become"
"Inject more" i said since what he said was true but Tenzo was not able to use any impressive Wood Style Jutsu's but Obito and Madara were able to use powerful Jutsu's the only way that would make sense was if they had more of Hashirama Cells implanted in them.
"Kabuto bring in a few more Test tubes of Hashirama Cells."
-----------
Orochimaru implanted about 5 more Testubes of Hashirama Cells and i decided that much was enough since i could feel the huge gain in power and i was satisfied with it and i didn't want to take the risk of implanting more Hashirama Cells i am having to use about 25% of my Chakra to Suppress it and as Orochimaru said it may take around a week for the Cells to get Familiar with my body, i could feel that the Hashirama Cells was merging with my cells.
'I see, so thats why Madara took so long to awaken the Rinnegan, when my Chakra and the Chakra from the Hashirama Cells are equal the Rinnegan should awaken since that would balance everything out, and when Madara implanted the Cells his reserves were already bigger than anyone other than Hashirama and he was getting old and the more older you grow the slower your chakra increases thats the reason why it took him so long to awaken the Rinnegan but that shouldn't be the case for me, in about 3 Years it should awaken, and i can also feel my Chakra reserves growing much faster and as i had expected even though only a small amount of Hashirama Cells were implanted to me, as its getting more adjusted with my body even that chakra is increasing.'
"The Transplant is successful but i suggest you take it easy and for the next week we shall only be doing Taijutsu Training since i dont want you dying because you lost control over the Hashirama Cells and i shall also begin teaching you Kenjutsu from tomorrow, and for wood style jutsu you will need to learn that on your own i cant teach you since i dont know any. but for now i suggest you rest"
I then left and started heading towards my room, over the past month i have been able to create the Chidori Stream, originally i expected it be easy because of my knowledge of my previous life and the knowledge of the original Sasuke but creating this was not easy since i my whole body would get electrocuted everytime when i did not control the Chidori Properly but i had finally finished that and i have now started
I then entered my room and locked my door and began thinking 'What am i going to do in this world, the Original Sasuke had a goal and that was to kill Itachi but i really dont care about killing him, whether he lives or dies doesn't really bother me and unlike him i dont have a goal but i have to get stronger because of all the things that will soon happen but what after the war?, i dont want to have to live my whole life as a rouge Ninja but at the Same time going back to konoha is not that simple since i will most probably be put under probation, be interrogated and they will have a Yamanaka go through my memories and that is something i cannot allow, i could take over the sound village after killing Orochimaru but that is not exactly practical for me at this time, even though i will probably be the strongest person after awakening the Rinnegan the five villages wont stop sending shinobi after me if i remain as a rouge and i become that powerful and i dont want that to happen but going back to Konoha wont be easy either but there is probably one way that might work.'
'Well i still have time for all that to happen but for now i need to get as strong as possible before the next three years'
