I came out of Orochimaru's room after sealing his corpse, and found Kabuto standing there with medicines.
"Are you Orochimaru or Sasuke?"
"Kukuku! What do you think?"
Kabuto smiled, thinking that Orochimaru successfully took over my body.
I immediately flared my Sharingan, and put him to sleep.
Now, let's use Tenjin.
Blood dripped from my left eye, and I felt pain throughout my body, especially my eyes.
I entered his mindscape, and found his memories.
Let's see...
Medical knowledge... hmmm, copied.
Spying knowledge... copied.
Orphanage memory... Nah.
Edo Tensei... copied! Well, it isn't really perfect, but it will do the job.
Shin... it seems that he escaped when Orochimaru lost to Itachi. Oh well. He will approach me himself sooner or later.
I started feeling tired, so I stopped using Mangekyo Sharingan. I need abundant chakra to keep suppressing Orochimaru afterall.
Well, I obtained everything of worth from Kabuto already. I don't need him to go around digging graves. He is too dangerous to be left alive.
So, I slashed off his head.
Then, I went to the underground prison of the base, and looked at the prisoners.
"Orochimaru is dead. You are free now."
"Thank you Sasuke-sama!"
"I need the six people from here to assist me. I will free you all in some days."
Hearing this, six people stepped forward, while the rest of them shook in fear. They probably thought that I will have them kill each other to find the strongest, like Orochimaru.
The six who were left behind got ready to attack each other, to prove who is the strongest. But I put them all under genjutsu, and started dragging them where I killed Kabuto.
'Edo Tensei!'
I said that Kabuto is too dangerous to be left alive. But what about undead, and under my control? He is too valuable.
"Huh!? What happened!?"
As Kabuto got revived, while he was busy being shocked by his state, I put the control seal in his head.
"Prepare to transplant Hashirama cells in me without getting Hashirama's face on my body. Get me Sound Five's DNA, and you will start cloning research."
"Yes Sasuke-sama."
"Good."
Then, I revived the Sound Five, supressed their personality because they are annoying, and ordered them to keep an eye on Kabuto. I can't fully supress his personality if I want him to research for me afterall.
Kimimaro is the bone guy. His current strength won't be more than a normal chunin in this imperfect state. Well, neither will Kabuto.
Jirobo's only use is for me to learn the Earth Style chakra absorption technique. Whatever its name is.
Sakon and Ukon are useless to me.
Kidomaru's webs are interesting. I wonder if it is a hidden jutsu that I can learn, or a kekkai genkai?
The most important one is Tayuya. Sound genjutsu is too OP for a world dominated by visual genjutsu. It might even work on the Otsutsukis.
Well, I will use my Mangekyo on them after getting Hashirama cells. My eyes are already feeling a bit itchy and dry.
"The preparations are ready."
Kabuto informed me, and I got ready to get the Hashirama cells. Not only this will increase my chakra reserves to a huge extent and give me Wood Release, but also allow me to use MS without any side effects.
These are not Hashirama cells, but Hax cells.
I did the implanting myself with Shadow Clones. Afterall, I had Sharingan and Kabuto's memories, who had helped in implanting Hashirama cells on Orochimaru too. I implanted a small amount under my eyes, and I could feel the healing effect, instead of it trying to takeover my own cells.
As expected, Indra and Asura's cells are compatible.
I then implanted some cells on my right hand, since my left hand will have the Yin seal. I don't want any risks.
After a week, the process was complete, and I felt that I have adapted to the upgrade. The only problems are the white patches, which will take time to become normal.
I tried growing a wooden stick out of my hand, and it worked. I sealed it away so that Yamato can't determine that someone with Wood Release was here.
"Now... let's see... Tenjin!"
I used Tenjin on Tayuya, and this time, I didn't feel any pain. Hashirama cells are amazing!
Now, let's see her memories... How does she use sound genjutsu...
Oh. Hmm... I see... So that's how. Alright. Copied.
Likewise, I copied Jirobo's earth dome chakra absorption jutsu.
Sadly, Kidomaru's spiderwebs are a kekkai genkai. But I got a contract of Rashimon Gates!
I wonder how many I can summon?
Well, I was done now. I will need to practice what I have learnt, and it will take some time. Now, it was time to go.
Let's get Suigetsu now.
