Inside the capital city, at the Uchiha Secret Technique Research Institute
An Uchiha clansman was fiddling with the Sharingan in front of him.
Although the Uchiha Clan doesn't intentionally collect Sharingan, those who sacrifice their lives often hand over their Sharingan to the clan for future generations to use.
For research purposes, and also to make the Sharingan even more powerful, Uchiha Takashi specifically dispatched a group of people to study the Sharingan.
There are generally two ways to study the Sharingan: one is to study the one's own, and the other is to study the Sharingan transmitted by Uchiha Takashi.
The Sharingan before them was sent by Uchiha Takashi, a rare Three-Tomoe Sharingan.
At this moment, the researcher's eyes gleamed, his Sharingan swirling within them, his hands fiddling with something, while he muttered repeatedly, "First like this, then like this, and then like that!"
As he continuously formed hand Hand Seals, the Sharingan he held in his palm suddenly began to spin. Then, he felt a flash of light before his eyes, and the Sharingan in his hand lost its luster, turning from blood red to a deathly white.
But at the same time, a small white mouse that he had just killed by poking it, which he had placed aside, miraculously came back to life.
The researcher watched as the revived mice, panting heavily, their eyes gleaming, shouted, "I did it! I did it! Hey, I made it!"
The researcher passing by only glanced inside twice before walking away. It's common for researchers like him to make strange noises; there's no need to make a fuss about it.
However, before the researcher had gone far, the other researcher rushed out, grabbed him by the collar, and pointed to a deathly pale bead and a white mouse in his hand, saying, "Resurrection! I did it! I did it!"
The researcher calmly slapped his hand away and asked in a very composed manner, "Oh, what kind of life-saving skill have you developed?"
As he spoke, the researcher pointed to a row of laboratories on the other side. "That guy over there was researching magic to bring the dead back to life, and he almost killed himself in the process."
Later investigation revealed that his so-called resurrection was merely a way of returning his own life force to a dying person to bring them back to life. Fortunately, he only used a small mouse at the time.
It didn't significantly erode his vitality; it only caused him to fall into a coma due to the sudden loss of some of his life force.
After finishing his sentence, the researcher pointed to another laboratory and said, "That researcher spent Tenten in there tinkering with magic to bring the dead back to life, but in the end, all he produced was a pile of sand and a pile of paper; nothing else."
It's not fair to say there was absolutely nothing; at the very least, he used sand and paper to recreate the shape of a former dead person.
What kind of successful resurrection are you talking about? Is it using water, wind, or fire?
The Uchiha researcher shook his head, looking indignant, and said, "How can you compare me to trash like them?"
They all used external forces, but I use the Sharingan of our Uchiha Clan! By consuming just one Three-Tomoe Sharingan, I can revive anyone who dies within one minute!
The Uchiha researcher spoke with an expression full of pride, while the previously calm researcher's eyes widened suddenly, and he grabbed the researcher by the collar, saying, "What do you mean by consuming Mitsudomoe? Explain yourself!"
Don't tell me that the pale eyeball you're holding, the same one as Hyuga's Byakugan, is my damn Three-Tomoe Sharingan!
Because he got too excited, he used too much force, causing the Uchiha researcher to suddenly lose his breath and frantically pound on his hand, yelling, "I can't... I can't breathe! Let go! Let go!"
Inside the office, Tatsu Uchiha stared at the deathly pale eyeballs in front of him, then looked up at the Uchiha researcher standing before him with his head bowed low, and sighed.
"So that's your reason for losing a Three-Tomoe Sharingan?"
The Three-Tomoe Sharingan is a treasured possession of the Uchiha Clan. Even when used for research, it cannot be damaged casually; any damage would result in legal consequences.
By sheer coincidence, this researcher completely destroyed the Three-Tomoe Sharingan, and kept saying it was a method of bringing the dead back to life.
This incident escalated to the point where it reached the ears of Tatsu Uchiha, the highest-ranking government official in the capital.
The researcher maintained his claim. "That's right, this thing can resurrect people, even those who die within a minute."
"By consuming just one Sharingan, one can turn fantasy into reality and reality into fantasy. Although it only lasts for a minute, it's still a miracle!"
"So this is your excuse for losing a Three-Tomoe Sharingan?" The Uchiha research group leader said angrily, "Do you know how long I begged the clan leader for that Three-Tomoe Sharingan?"
Tatsu Uchiha extended a hand, interrupting the Uchiha research group leader, and then gently inquired...
"Let me ask you first, is what you're saying true? Can you really turn fantasy into reality, and reality into fantasy?"
The Uchiha researcher nodded firmly. "That's right, this is the ability of the technique I developed. I named it Izanagi reverses illusions and reality."
This is something I created based on Uchiha Shin's Dream Path ability and Tsukuyomi. The only side effect might be that it requires consuming one Three-Tomoe Sharingan.
Tatsu Uchiha was silent for a moment, then asked, "Besides us, who else knows about this technique?"
The researcher shook his head. "That's all. I was brought here as soon as the research was completed."
Tatsu Uchiha nodded, then said seriously, "This must never be told. No one can know, not even members of our Uchiha Clan!"
Tatsu Uchiha quickly grasped the terrifying nature of this thing in a short time.
This thing seems a bit useless, as it can only be used to revive someone who has died within a minute. But it is a revival, and a one-minute revival is extremely useful when the opponent has no prior information.
And this thing is about resurrection! Who can resist the temptation of resurrection? Most importantly, it allows the Mitsudomoe to be used outside the body, making it far more dangerous.
Let's put it this way: having this thing is like having an extra chance to revive, and the thing is, it can be accumulated indefinitely. So, once other people find out about this, won't they start collecting Sharingan?
How many Three-Tomoe Sharingan are left in the Uchiha Clan? Will other clan members try to steal the Sharingan from each other?
Although he didn't want to believe that the Uchiha clan would harm their own members, it was hard to say what the more extreme Uchiha might do in their pursuit of power.
At that time, before the Senju Clan and other clans could even attack the Uchiha, the Uchiha would fall into chaos and destroy themselves.
Tatsu Uchiha sighed, gazing towards the front lines. "I'm sorry, clan leader, I don't know whether this news is good or bad for you."
(Regarding the internal strife within the Uchiha Clan, specifically the Izanagi conflict and the birth of Izanami, the timeline should be between Madara Uchiha's defection or his death by Hashirama and Hashirama's death.)
This is the only way to explain why the Uchiha Clan would ruthlessly hunt down their own members: there were no external enemies, and Hashirama was still alive. Without external threats, the Uchiha Clan could naturally and freely engage in internal strife.
Therefore, the more extreme members of the Uchiha would kill each other in order to collect the Three-Tomoe Sharingan.
Furthermore, when this timeline occurred, the Uchiha leader was already Forehead Protector, which definitely meant he was from Konoha. It wasn't specified which period of Konoha it was, but it's speculated to be around this time, and it has absolutely no connection to the Sengoku period.
If this had actually happened during the Warring States period, many Uchiha clan members would definitely have used it; at the very least, Uchiha Izuna n't have died.
As the younger brother of the Uchiha Clan Head, how could he not know that even with his Mangekyō Sharingan Izanagi, and after being hit by a Flying Thunder God Slash, he wouldn't have used Izanagi?
Therefore, the time period can only be between Madara's escape and Hashirama's death.
