Somewhere else, Uchiha Fugaku had arrived at the entrance of Orochimaru's laboratory.
Because of the last incident, Orochimaru was now very idle.
At the moment, Orochimaru was studying the material from Uchiha Sasuke.
When Guren said that Uchiha Fugaku was visiting, Orochimaru was startled, thinking that the other party was coming to find fault.
It was worth mentioning that Orochimaru's lab assistant was now Guren.
Kimimaro, Jūgo and others had already been mixed into Uchiha Madara's training team under Orochimaru's arrangement.
"What's he doing here?"
Orochimaru's eyes fluctuated for a moment. Looking at the two scarlet eyes on the petri dish in front of him, his eyes slightly moved.
These two eyes were Mangekyō cultured by partial cloning technique based on the blood provided by Uchiha Sasuke.
Although they had the appearance of Mangekyō, this pair of eyes had no Eye Technique capability at all.
Simply put, these were false Mangekyō.
It was worth mentioning that, for some reason, the patterns on these eyes were different from Uchiha Sasuke's.
Orochimaru could only attribute this to the particularity of the Sharingan.
Of course, Orochimaru hadn't seen Uchiha Izumi's eyes.
If he had seen Izumi's eyes, he would have been shocked to find that the Mangekyō he cloned were just like Izumi's pair of Mangekyō.
Yes, the blood and other experimental samples given to Orochimaru by Uchiha Sasuke were all from Uchiha Izumi!
This was what Sasuke negotiated with Izumi.
The two didn't want to listen to Uchiha Fugaku's advice at all; they were going to save Uchiha Itachi.
"Let him in."
Putting away the eyes in front of him, Orochimaru faintly said so.
After a while, Uchiha Fugaku appeared in front of Orochimaru:
"Orochimaru, do you have a way to evolve Mangekyō into Eternal Mangekyō?"
Uchiha Fugaku cut to the chase. He didn't like Orochimaru, a gloomy guy, and didn't want to pretend with him.
"Hmm?"
Hearing Fugaku's words, Orochimaru's golden pupil narrowed. He didn't expect that Uchiha Fugaku would ask the same question as Uchiha Sasuke.
'Should I say, 'Like father like son'?'
Orochimaru's long tongue licked his lips. Then, as if he had no intention of doing so. He said:
"As far as I know, Fugaku-san's eyes aren't Mangekyō anymore, right? "
"It's for Sasuke. Now that the shinobi world is in turmoil, Sasuke's strength is too weak for me to feel comfortable."
Uchiha Fugaku said so and directly pulled out a pair of Mangekyō saved in a small jar.
It was the same pair that he wanted to give to Uzumaki Nagato.
"This is a pair of Mangekyō Sharingan with Mangekyō level Eye Technique capabilities in them."
Uchiha Fugaku said with a slight frown, "These eyes aren't from Sasuke's blood relatives, so they can't be fused with Sasuke's."
"Oh?"
Hearing Uchiha Fugaku's words, Orochimaru was slightly stunned, and then his eyes flashed.
Orochimaru also knew about the Uchiha clan's method of fusing Mangekyō to upgrade Eternal Mangekyō, and he even had a bolder assumption.
He felt that the reason why the Uchiha clan, having changed their eyes, became Eternal Mangekyō was because of the evolution that occurred after the replacement eyes themselves withstood the physical immune rejection reaction.
In other words, it was the other pair of Mangekyō that stimulated the Uchiha blood and produced some hormones in their body that made the Mangekyō evolve.
And the reason why the Uchiha clan passed down the means to transplant from blood relatives...
That's because the physical reaction caused by the blood relatives' eyes was smaller than that caused by a pair of unrelated eyes.
The success rate was higher.
During the Warring States Period, probably because medical jutsu were underdeveloped, only close relatives survived, so this method was passed down.
Orochimaru's eyes flickered. He increasingly felt that his guess was the true past of the Uchiha clan.
Originally, Orochimaru was wondering what to do with the cloned pair of Mangekyō.
Unexpectedly, Fugaku directly brought a pair of Mangekyō with Eye Technique in them.
This was much more workable...
"Patriarch Fugaku, do you have a method of transferring Eye Technique capabilities to the other Uchiha clansmen?"
Orochimaru became more and more interested.
Unlike the original, Orochimaru's current body could still be used because it was enhanced by the exam space.
Moreover, Orochimaru wasn't sure whether the Sky Walk and other rewards rewarded by the exam space were for his soul or his body.
So, Orochimaru wouldn't give up this body so easily.
"The method of transferring Eye Technique capabilities?"
Hearing Orochimaru's words, Uchiha Fugaku paused and nodded his head.
"You have a solution?"
Uchiha Fugaku looked at Orochimaru with some shock. Sannin Orochimaru he had previously fought to, and they had been to the battlefield together.
But Orochimaru, within a short period of time, found a way to upgrade the Eternal Mangekyō. Wasn't that too abnormal?
Uchiha Fugaku had just recovered from the shock when she heard Orochimaru's voice.
"By injecting the Eye Technique capabilities of these Mangekyō into Sasuke's cloned Mangekyō Sharingan and moving it into Sasuke's eyes, Sasuke's eyes will become Eternal Mangekyō."
Orochimaru looked at Uchiha Fugaku with great interest and then was about to tell Fugaku that Sasuke had approached him and that he had finished cloning Sasuke's Mangekyō when a semi-illusory figure suddenly emerged from in front of Uchiha Fugaku.
It was Uzumaki Nagato who used Akatsuki's ring to wield the Astral Projection Jutsu.
"Patriarch Fugaku, traces of the allied forces of the five major shinobi villages have been found. You will lead Akatsuki's group to meet them."
Uzumaki Nagato's voice carried a rare trace of urgency, causing Uchiha Fugaku's face to turn mournful.
Uzumaki Nagato and Uchiha Madara, even Uzumaki Kushina, had to prepare means to seal Ōtsutsuki's people. So, in the front lines of the battle, the only ones to hold back the shinobi alliance were Uchiha Fugaku and the other Akatsuki members.
"Yes."
Uchiha Fugaku nodded, took out a small scroll, drew something, and handed it to Orochimaru.
Then turned around and walked away without saying a word.
For Orochimaru, Uchiha Fugaku knew that threats meant nothing to him, so he simply left without saying anything.
He believed that Orochimaru would be able to handle it; if, for example, he didn't want to face the wrath of the entire Uchiha clan.
"Fugaku-san, wait a minute."
Orochimaru's voice suddenly sounded, and Uchiha Fugaku stopped.
"There are still some experiments that haven't been finished. Being disturbed by the Allied Shinobi Forces wouldn't be good."
With that, Orochimaru threw out three scrolls under Uchiha Fugaku's surprised gaze.
"These three have special abilities that could cause some problems for the shinobi alliance."
Uchiha Fugaku heard this, glanced at Orochimaru, and opened the scrolls one by one.
When he saw the three people on the scroll, he instantly froze.
He didn't think that Orochimaru would have these three in his hands!
Uchiha Fugaku took a deep look at Orochimaru. At this moment, he understood why Orochimaru was someone difficult to deal with.
The Second Mizukage, the Fourth Mizukage, and even the former Hanzō of the Salamander of Amegakure.
He could casually throw these Impure World Reincarnated people to him. Uchiha Fugaku was sure that Orochimaru had stronger cards in his hands.
Watching Uchiha Fugaku leave, Orochimaru's mouth slightly smiled.
"Go to Uchiha Sasuke and tell him that the experiment is ready to be completed and that he should come to receive it."
"Yes."
Guren's figure appeared behind Orochimaru at some point, and after a respectful salute, retreated.
Ten minutes later, Guren arrived with Uchiha Sasuke.
What surprised Orochimaru a little, was that Sasuke came with a girl from the Uchiha clan.
"This is ..."
"Uchiha Izumi."
Izumi graciously stepped forward and gently held Orochimaru's hand with both hands and shook it up and down twice before saying, "I'll be the one accepting the experiment."
Orochimaru glanced at Uchiha Sasuke, subconsciously thinking that Uchiha Izumi was the scapegoat that Uchiha Sasuke had found.
Just as he was about to tell Sasuke that he had cultivated his eyes with his blood, Uchiha Sasuke suddenly spoke up and said:
"The blood I provided was from her."
"Is that so? All right."
Orochimaru licked his lips without any anger from Sasuke's scheme.
