Flying Fortress.
Laboratory.
Sasuke seemed to have made up his mind and proactively found Shinji: "Shinji, I want to undergo the First Hokage cell transplant surgery!"
Shinji, who was experimenting, raised an eyebrow and glanced at Sasuke: "Thought it through?"
Sasuke nodded heavily: "Yes, I asked Mumei, Yakumo, and the others. I know this transplant surgery has risks, but I don't care!"
Shinji smiled: "Don't care?"
"Before the upcoming upheaval, I don't want to sit stupidly in the audience!" Pausing, Sasuke continued: "Don't forget, I am an Uchiha just like you. I won't shame the Uchiha clan!"
Shinji put down the work at hand.
He originally planned to bring this up with Sasuke proactively. Unexpectedly, Sasuke brought it up first.
Looking at the eager Sasuke, Shinji knew his thoughts at this moment, so he said: "If you really want to undergo the First Hokage cell transplant surgery, you must first clear the 'Cursed Seal' on your body."
"Clear the 'Cursed Seal'?!"
Sasuke was stunned.
Regarding the 'Cursed Seal' on his shoulder, his feelings were complicated.
Although the 'Cursed Seal' had been trying to erode his body, the strength improvement after activating the 'Cursed Seal' was real.
Currently, with the 'Cursed Seal' amplification, he could only barely maintain a lower-middle level in the organization. If without the 'Cursed Seal', he worried he might directly become the bottom.
Seeing Sasuke somewhat tangled, Shinji explained: "The 'Cursed Seal' is Orochimaru's inferior imitation of 'Sage Arts'. Besides natural energy, it also contains many impurities, which will affect your efficiency in Yin-Yang fusion and breeding the 'Power of All Creation'."
After listening, Sasuke gritted his teeth: "Okay, please help me clear the 'Cursed Seal'!"
Shinji nodded, then pressed one hand on Sasuke's shoulder and pulled fiercely.
Squelch...
Instantly, a large lump of flesh and blood was pulled out from Sasuke's shoulder by Shinji.
"Ah!"
Sasuke instantly wailed in pain.
Shinji ignored the wailing Sasuke, putting the lump of flesh and blood pulled from Sasuke's shoulder into a petri dish on his own.
A few breaths later, Sasuke recovered and asked Shinji while clutching his shoulder: "Solved just like that?"
Shinji glanced at Sasuke: "What else?"
Sasuke opened his mouth, but didn't know what to say.
Back then, the village spent a lot of effort to help him solve the 'Cursed Seal', but the result was only barely sealing the 'Cursed Seal'.
Unexpectedly, falling into Shinji's hands, with just a gentle pull, the 'Cursed Seal' was completely cleared.
Besides marveling, it also made him realize how big the gap between his current self and Shinji actually was!
Subsequently, Sasuke shifted his gaze, looking at the lump of 'Cursed Seal' Shinji pulled from his body in the petri dish.
At this time, the 'Cursed Seal' in the petri dish was just a fist-sized cell tissue. It constantly turned and spasmed, seeming to look for a host.
Sasuke frowned: "This is the 'Cursed Seal'?!"
While observing the 'Cursed Seal' in the petri dish with instruments, Shinji answered casually: "No, this lump of flesh and blood is your cell tissue, it's just the carrier of the 'Cursed Seal'."
Sasuke asked: "Then what is the 'Cursed Seal'?"
Shinji said in a deep voice: "See those black marks on the cell tissue? Those are the 'Cursed Seal'!"
Sasuke said: "Those things like formula markings?"
"Yes, that is the main body of the 'Cursed Seal'!"
Shinji nodded.
Orochimaru was a genius, this was beyond doubt.
The 'Cursed Seal' he developed, to some extent, had the same effect as the Otsutsuki clan's 'Karma'!
It's just that compared to the Otsutsuki clan's 'Karma', Orochimaru's 'Cursed Seal' appeared quite crude, easily cracked and cleared.
Sealing the petri dish well, Shinji fell into contemplation.
With his current chakra level and ability to control chakra, creating his own 'Karma' wasn't difficult. Moreover, he had the 'Cursed Seal' as a ready-made reference at hand.
Upgrading existing technology was much easier than creating out of thin air.
After this thought arose, he suddenly realized 'Karma' was just a tool. It itself had no good or evil; how to use it depended entirely on the user's intention.
In other words, 'Karma' could become a tool to seize others' bodies, and could also become a tool to empower them.
Seeing Shinji falling into contemplation, Sasuke stood obediently aside, waiting quietly.
After a moment, Shinji recovered and instructed Sasuke: "The 'Cursed Seal' on your body has been cleared. You can undergo the transplant surgery anytime. Do you want to undergo the surgery now, or go back to rest and undergo the surgery tomorrow?"
Sasuke shook his head hurriedly: "I don't need rest!"
Shinji instructed: "In that case, lie on the operating table!"
As the reincarnation of Indra Otsutsuki of the current generation, his success rate of fusing First Hokage cells was inherently higher than others. Plus he now possessed the Eternal Mangekyo Sharingan. Although one eye lost pupil power, the overall pupil power still exceeded ordinary Mangekyo Uchiha. So as long as his will was firm, the success rate of the First Hokage cell transplant surgery was very high.
Lying on the operating table, Sasuke took a gentle breath.
Shinji skillfully prepared the fusion agent and inhibitor, saying: "Since you already know the risks of the surgery, I won't repeat them. You don't need to do anything during the surgery, just concentrate on controlling the Yin Release chakra in your body to fuse with the Yang Release chakra in the First Hokage cells."
"Understood!"
Sasuke nodded seriously.
Shinji wasted no words, starting the surgery directly.
First injecting inhibitor, then surgically implanting First Hokage cells, finally injecting fusion agent and suturing the surgical wound. Shinji only spent four minutes on the entire surgical process.
After completing the surgery, Shinji retreated to the side, observing Sasuke on the operating table.
"Ah!"
A few minutes later, Sasuke roared, his body curling up, his whole face flushed like sauce.
Shinji took out the 'inhibitor': "If you really can't bear it, I can inject another dose of 'inhibitor' for you!"
The curled-up Sasuke grabbed Shinji's arm fiercely, saying word by word: "No need..."
He had learned beforehand that although 'inhibitor' could increase the success rate of transplant surgery, it would also greatly discount the surgical effect due to excessive inhibition of Yang Release chakra in First Hokage cells.
For example, Yamato, who also underwent First Hokage cell transplant, had 'Wood Release' far inferior to Karin and Mumei, because Orochimaru injected too much inhibitor into Yamato to improve the success rate of the surgery at that time.
