Among the clan members killed on the night of the massacre, there were many Jonin possessing the Three-Tomoe Sharingan, so it was impossible for Itachi's actions to have gone completely unnoticed.
So, what considerations led Konoha to not react?
This is very thought-provoking.
"If you won't tell me, then I'll investigate it myself."
Once he had his suspicions, Sasuke no longer felt such a strong desire to kill Itachi; at the very least, Itachi couldn't die before the truth was uncovered.
"...As you wish."
If this were before, Itachi would definitely have stopped Sasuke from investigating the truth, as it would be too dangerous.
Things are different now. The Third Hokage is dead, and Danzo is under his control. As long as he stays alive and makes occasional appearances, the remaining worthless Konoha Ninja would surely not dare to touch Sasuke.
Moreover, the current Sasuke is no longer an ordinary Genin; he is not someone anyone can bully.
The battle between the two brothers came to a halt. When Itachi arrived at the location where Kisame and Naruto were fighting, he saw the two of them bickering like elementary school students.
"Kisame, let's go."
To prevent Kisame from losing face further, Itachi quickly called him and left.
"Coming, Itachi!"
Kisame also didn't want to continue bickering with Naruto. It was only because Naruto was quite strong—if he didn't take it seriously, he genuinely wouldn't be able to defeat Naruto. But if he did get serious, the commotion would be huge. At that point, it wouldn't be him fighting Naruto, but Naruto and the other Konoha Ninja fighting him.
To avoid being ganged up on, he shamelessly bickered with Naruto. If it were anyone else, would they dare try this?
Anyone who dared to talk to Kisame like that would have the shit beaten out of them... Itachi took Kisame and left Konoha. Their objective for this visit had been achieved, and there was no point in staying in Konoha any longer. Knowing that Sasuke was doing well was enough.
After Itachi and Kisame left, Naruto found Sasuke standing still, deep in thought, and said casually, "Your brother isn't as bad as the rumors say."
"You think so too?"
"Of course. Kurama didn't sense any malice from him."
Itachi claimed his goal in coming to Konoha this time was Naruto, but his true objective was to show his face to protect Sasuke. Therefore, he held no malice towards either Naruto or Sasuke.
Naruto had long known that Kurama possessed the ability to sense malice, so the moment he saw Itachi, he asked Kurama if Itachi harbored any ill will toward them.
The result was excellent: Itachi held no malice.
"...I will definitely uncover the truth behind the Uchiha Clan massacre."
Learning from Naruto that Itachi held no malice toward him further strengthened Sasuke's resolve to uncover the truth.
"So, why don't we ask the amazing Uncle?"
"Will Boss Ge tell me the truth?"
"Give it a try. It doesn't cost anything anyway."
"...You want to know the truth behind the Uchiha Clan massacre? Fine, that'll be ten million Ryo for the information."
With Itachi and Kisame no longer 'blocking the road,' Sasuke and Naruto quickly arrived at the Internet Cafe and immediately asked Ge Liang for the information.
It was just different from what Naruto expected... What happened to not costing money? Ten million Ryo for information? You might as well just rob us!
Naruto's expression was too easy to read. Ge Liang knew what he was thinking without him having to say it, but he didn't mind.
To be honest, he was basically robbing them right now.
This information was worthless in Ge Liang's mind, but it was worth a fortune to Sasuke. If Ge Liang hadn't had a shred of conscience and only asked for ten million Ryo, Sasuke probably would have agreed even if he had asked for fifty million Ryo.
"Fine, ten million Ryo it is. Boss, tell me first, and I'll bring the money tomorrow."
"No problem."
Ge Liang trusted Sasuke. After all, the monk can run, but the temple cannot. Could Sasuke really dare to defect after learning the information?
"The Uchiha Clan massacre is a very complicated matter. I'll tell you slowly..."
In fact, there were many reasons for the Uchiha Clan massacre.
Back then, after the final battle between Senju Hashirama and Uchiha Madara at the Valley of the End, the Uchiha Clan gradually revealed their dissatisfaction with Hashirama monopolizing Konoha.
They attempted to dismantle the Senju family's dominant position, even plotting to seize the Hokage's throne.
The Senju and other clans held a deep grudge against Uchiha Madara's rebellion; trust in the Uchiha was lost, and the rift grew daily. Senju Tobirama, in order to prevent a major incident while also being unable to wipe out the Uchiha completely.
Thus, the Second Hokage, Senju Tobirama, established the Konoha Military Police Force, with the main positions held by Uchiha Clan members. This served both as an expression of trust in the Uchiha and as a means to monitor their every move.
From then on, the Uchiha's prestige and power in Konoha reached its peak.
At the same time, the Uchiha Clan members, led by Uchiha Fugaku, also gradually grew dissatisfied with Konoha.
Especially during the Nine-Tailed Fox's Attack, they were only allowed to follow Konoha's command and not fight, and they were hated by the people they policed. This dissatisfaction reached its peak.
The Konoha higher-ups, led by Hiruzen Sarutobi, were aware of the Uchiha's actions. Publicly, Hiruzen Sarutobi advocated for a peaceful resolution rather than using force, but he turned a blind eye to Danzo Shimura's attempts to wipe out the Uchiha Clan in one fell swoop.
When the peace advocate, Uchiha Shisui, was ambushed by Danzo and died by suicide, a peaceful resolution became impossible, though Itachi still wanted to make an effort.
When the Uchiha were preparing to stage a rebellion at the Naka Shrine, Itachi was monitoring them from a tree outside the shrine, simultaneously reporting to the Konoha higher-ups.
The higher-ups were greatly surprised. After the report, Danzo Shimura found Itachi and threatened him with Sasuke to force him to carry out the massacre. Uchiha Itachi had no choice but to agree. Itachi found the Masked Man (Uchiha Obito) and planned the massacre mission on the condition that he would not harm the Village or Sasuke.
That night, the Masked Man used Kamui to arrive in front of the Konoha Military Police Force and began his attack, while Itachi simultaneously started killing the rebellious clan members.
After that, Itachi stood on a utility pole, feeling saddened as he watched Sasuke return. Itachi went home, preparing to kill his own parents, but he couldn't bring himself to do it. His parents entrusted Sasuke to Itachi, believing him to be a "kind person."
Then Sasuke returned home and was struck down by Itachi's Genjutsu.
Before Itachi left Konoha, he threatened Danzo, stating that if he harmed Sasuke, he would sell all the information to other countries.
Hiruzen promised Itachi he would look after Sasuke, while Itachi joined the "Akatsuki" to prevent the Masked Man from attacking Konoha.
At this point, the Uchiha Clan Massacre incident concluded... "Where is Danzo Shimura?"
It was clear that Sasuke was extremely agitated after hearing the truth told by Ge Liang.
Firstly, he hadn't expected Konoha to be genuinely so dark.
Secondly, he never imagined that Itachi massacred the clan simply to protect him.
With resolute eyes and trembling hands, he wished he could immediately kill Danzo, the culprit.
Let alone Sasuke, even Naruto found it somewhat unacceptable after hearing it.
