Originally, Hashirama cells were used to balance the Sharingan on his arm, but now that the Hashirama cells are still there and half of the Sharingan are gone, Danzo's body is on the verge of losing control.
Forget about fighting, if he extracts just a little more Chakra, the Hashirama cells within him show signs of rampaging.
As a Ninja, being unable to extract Chakra makes one useless, and no ambition, however grand, can change that.
This arm was transplanted by Orochimaru, and now the patient is still here, but the doctor is dead.
What to do?
In Danzo's secret warehouse, there were still Sharingan preserved from back then, Medical Ninja, and even facilities and tools, but the skill level of these people was simply insufficient to transplant Sharingan for him.
Since the doctor is dead, then we shall revive the doctor!
If anyone in this world understood the Third Hokage, Hiruzen Sarutobi, Danzo would say he was second, and no one would dare claim first.
The Third Hokage's wife, son, grandson, disciples, and subordinates—none of them understood his old partner as well as Danzo.
The two had been entangled in disputes for seventy years, knowing what the other was thinking with just a glance.
When Jiraiya was forced into the position of Fifth Hokage, Danzo secretly sent people to steal many of the Third Hokage's Ninjutsu notes.
Many people say that Orochimaru's research into Ninjutsu is profound and far-reaching, but they don't realize that his teacher, the Third Hokage, also had considerable research into many Forbidden Jutsu.
Years ago, the Third Hokage discovered the Heavenly Cursed Seal Orochimaru left on Anko Mitarashi's neck.
Orochimaru had no intention of hiding it; with the skill level of a Ninjutsu doctor, even without Senjutsu, he could unravel its mysteries through his profound Ninjutsu knowledge.
The Third Hokage sealed Anko Mitarashi's Heavenly Cursed Seal, and afterward, he recorded the key points of this Jutsu, its dangers, and his own handling methods in his notes, leaving them for future generations.
Danzo acted decisively, studying the notes for two days.
After estimating a two to three-tenths chance of success, he immediately had Fu Yamanaka tie up Anko Mitarashi, who was eating dango.
Orochimaru was once also Danzo's subordinate, working for Root for a period, after which their relationship transitioned from subordination to alliance.
Danzo never expected that he himself would be the one to revive him in the end.
He leaned on his two crutches, with the unconscious Anko Mitarashi lying on the ground, surrounded by dense Jutsu formulas drawn with her as the center.
Sai took out a potion and injected it into Danzo's body, temporarily suppressing the rampage of the Hashirama cells.
Danzo's voice was dry: "Begin."
The Root Ninja, one by one, walked into the center from the gaps in the Jutsu formulas, their faces expressionless.
They cut their wrists, allowing their blood to flow into the Heavenly Cursed Seal on Anko Mitarashi's neck.
After nine Ninja had perished, the Heavenly Cursed Seal emitted a faint red light.
Danzo gestured, and Fu Yamanaka took out a half-meter-tall glass vessel.
The bottom of the vessel had a Sealing Technique formula, and inside was a small, finger-thick piece of flesh.
This was the original Hashirama cells extracted from the First Hokage's corpse.
Danzo used Ninjutsu to connect the Hashirama cells with the Heavenly Cursed Seal.
His own expertise in Sealing Technique was very high, allowing him to break the seal applied by the Third Hokage and fully open the Cursed Seal.
Then, his palm grasped something, and he pulled his arm outwards with force.
A large mass of white, vibrant life energy transformed into a giant snake and burst forth from Anko Mitarashi's neck seal.
The giant snake rapidly expanded, its mouth opened, and Orochimaru, covered in mucus, crawled out of the snake's mouth.
The sudden revival made Orochimaru very uncomfortable; he lay on the ground, gasping for air.
Danzo then motioned for Fu Yamanaka to take Anko Mitarashi, the tool, away.
She was, after all, a well-known Special Jonin in the Village; if she suddenly disappeared, it would certainly cause a stir, and Danzo was worried about any disturbances right now.
She was to be returned to where she was abducted from, and altering memories was a minor task for Fu Yamanaka.
After a while, Orochimaru recovered from the weakness of his revival.
He stood up, looking left and right, as the Root Ninja all assumed defensive stances.
"Oh? So it was you guys who revived me.
It's so dark here; is this Root?" he asked with a hint of sarcasm.
Danzo said solemnly: "It was this old man who revived you, Orochimaru.
This old man needs you to do something."
Orochimaru looked at him with a chilling demeanor for quite some time: "Danzo-sama, it seems your situation is quite bad.
The Hashirama cells have already started to backfire on your body?
Oh, it's overuse of the Sharingan, I understand.
It's Izanagi, isn't it?"
Danzo stated his request directly: "I need you to help me transplant new Sharingan, and quickly."
Even with the life energy provided by the blood of nine Ninja and Hashirama cells, and then using his Orochimaru-Style Body Replacement Technique to reconstruct his body, Orochimaru's current physical condition was still extremely poor.
Chakra is composed of physical energy and mental energy.
His physical energy was barely sufficient now, but his mental energy had mostly been sealed with his main soul by the Shinigami.
At this moment, he could hardly use any Chakra, and with a large group of Root elites glaring at him, he had very little room to resist.
He spoke of his difficulties: "This is probably impossible.
I don't have enough Chakra right now to perform such a transplant surgery."
As if guessing Danzo's reply, he spoke first: "You'll definitely say you have Medical Ninja under your command, and then you'll have me guide them during the transplant, right?
You don't understand the Sharingan, nor do you appreciate the rigor of science.
That won't work.
I must recover to my peak condition before I can perform the transplant.
You wouldn't want many oversights after the transplant, affecting its use, would you?"
Danzo narrowed his eyes, staring at him.
Orochimaru licked his lips: "How about it?
We're allies, after all.
You shouldn't mind me recovering my strength, should you?"
Danzo certainly minded, but he now needed more self-preservation capabilities and had to race against that reckless Jiraiya.
His time was extremely precious, not a moment to waste.
He couldn't control Jiraiya, so naturally, he couldn't control Orochimaru.
Now, Orochimaru, weak as he was, dared to negotiate terms with him.
What would happen once he recovered his strength?
But Danzo could only rely on Orochimaru to transplant the Sharingan for him now.
Abandon the Hashirama cells, abandon all the Sharingan?
Such an option was simply not within his plans.
He asked in a deep voice: "How do you intend to recover your strength?"
Orochimaru also put his mind to work, thinking about his current predicament, which he hadn't anticipated.
Soon, he held up two fingers: "First, have your subordinates use that Dead Demon Consuming Seal to release my soul.
Second, find my original body and let me reclaim the Chakra within it."
Danzo deliberated repeatedly; even making a deal with the devil was unavoidable now.
He had a scroll for the Dead Demon Consuming Seal in his possession.
He would have his subordinates, skilled in Sealing Technique, learn it.
Three days later, the Shinigami would descend.
