Uchiha Takashi's guess was not without reason, and some events at the front lines confirmed his suspicions.
On the front lines, although the Senju and Uchiha maintained a stalemate, friction was constant and frequent.
After all, even if you're in a standoff, you can still fight; there will be friction between patrol teams, reconnaissance squads, and other different groups.
However, no large-scale wars occurred, which can be considered a period of peace; this level of peace was basically the norm during the Warring States period.
It's not that there has to be absolutely no friction to be considered peace; that's impossible.
Even modern neighboring countries experience friction due to territorial disputes and other issues; it's just that they haven't resorted to firearms or escalated the conflict.
During a recent skirmish, a unique summoning beast suddenly appeared on the Senju Clan's side. It looked soft and squishy, and simply perched on the shoulders of the Senju clan members.
Based on observation, the summoning beast seems to be able to heal injuries; given enough time, it can revive a near-death Senju clansman.
Even minor injuries can heal quickly.
This has led to some unpleasant friction between the Uchiha and the Senju Clan.
After all, the Senju Clan is already physically strong, and now they have a healer with them, making them even harder to fight.
Anyway, the Uchiha were incredibly disgusting to be around. The Uchiha were strong in combat, but their opponents had built-in healing abilities! They were already tanky characters, and then they had healing abilities too – wasn't that disgusting?
They came from the underworld! This forced the Uchiha to strengthen their outer patrols to prevent being at a disadvantage in clashes and thus having their intelligence leaked.
With reinforcements added to the front lines, the 600 men at the front were proving insufficient. Therefore, the frontline commander Suke Uchiha, immediately reported the situation to headquarters and requested reinforcements.
The timing of this player report was incredibly precise; it arrived on his desk a short while after the live stream audience learned that another Mangekyō Sharingan had emerged.
Uchiha Takashi glanced at the report requesting reinforcements from the front lines, frowned, and sensed something was wrong, but he couldn't think about it in detail at the moment.
He looked at the clansman who had brought the news and said...
"Find out the reason why that Mangekyō Sharingan awakened, and also, take me there to him."
Uchiha Takashi rubbed his temples wearily. The Senju Clan had been strengthened, which was not good news for the Uchiha Clan, especially for him.
So what if he possesses the Eternal Mangekyō Sharingan? His plan to sweep across the entire Shinobi World by force failed before it even began.
Along the way, Uchiha Takashi listened quietly to the report from his clansmen, "Clan leader, the situation was rather dire when we arrived."
The new Mangekyō Sharingan's father died on the battlefield, in a conflict with the Senju Clan; the specific cause is currently unknown.
The child heard about this and instantly transformed from Futatsudomoe into Mangekyō Sharingan, and he was only seven years old.
The reason he developed Futatsudomoe was because his mother died on the battlefield...
Uchiha Takashi suddenly turned his head. "What? Say it again, when did he awaken the Mangekyō Sharingan?"
The Uchiha clansman froze on the spot, then quickly said, "Just recently, when news of his father's death came back..."
Uchiha Takashi finally realized something was wrong. His father, the reincarnation of Indra, had died on the battlefield, which caused him to awaken the Mangekyō Sharingan.
However, Indra's reincarnated father shouldn't have died on the battlefield, given his exceptional strength.
The most likely reason he died on the battlefield was that the Senju Clan was strengthened by the Katsuyu Summoning Beast!
Then the timing is wrong! Because according to this calculation, the time when this Indra reincarnation awakened the Mangekyō Sharingan should have been after the Asura reincarnation finished learning the Senjutsu!
Uchiha Takashi seemed to have sensed something. According to the principle that when Indra and Asura are entangled, if one becomes stronger, the other will inevitably become stronger. That means...
This time, Asura's strength wasn't due to the reincarnation of Indra from the Uchiha becoming stronger.
It was actually Asura's increased strength that caused Indra's increased strength! This was the exact opposite of his conjecture!
But this doesn't make sense! What other situation could cause such a sudden increase in strength besides the Uchiha Clan awakening the Sharingan Mangekyō Sharingan?
After all, Asura, how could he suddenly become stronger? The Senju Clan doesn't have any means to suddenly become stronger! That's impossible!
Could it be that a member of the Senju Clan inexplicably ended up in one of the Three Great Sage Lands, and then inexplicably learned some immortal Senjutsu?
Holy crap! Even novels wouldn't dare write something like this, it's absolutely impossible!
Of the Three Great Sage Lands, only the Toad's side actively recruits; the others all have to go there on their own. And the Katsuyu's side requires a master to guide you; otherwise, you simply can't get in.
Suddenly, an unrealistic yet perfectly reasonable idea popped into Uchiha Takashi's mind.
Could it be that the old man, Six Paths, noticed Uchiha Takashi's unusual behavior and then personally intervened to strengthen Asura?
Then, after Asura became stronger, through the brotherly entanglement characteristic of Hokage, Indra sensed it and also became stronger.
This isn't entirely unreasonable, because according to the original work, the Sage of Six Paths never died; he was hiding in the Pure Land throughout the entire series.
They only made a brief appearance in the final battle against Otsutsuki Kaguya, where Sasuke Uchiha and Naruto Uzumaki were given a power-up before fighting Otsutsuki Kaguya.
If we look at it that way, this guy does seem to have a way to strengthen Asura and Indra.
If this is the explanation, then it's not surprising at all that Asura suddenly became stronger, or even suddenly learned Senjutsu.
If you add the fact that the Old Man Six Paths was secretly plotting something—whether he actually intervened or was subtly guiding things—it would perfectly explain everything.
"Seriously, you son of a bitch! Hagoromo Otsutsuki, you old Feng are dead!" Uchiha Takashi cursed under his breath. "Playing this double standard game, huh?"
Sage of Six Paths: You said I, Old Feng, am dead? That's actually not so bad, thank you.
Just as Uchiha Takashi figured it out, the two had already arrived at where Uchiha Shin was.
At this moment, Uchiha Shin curled up in the corner, head down, silent, exuding loneliness.
Seeing this scene, Uchiha Takashi felt his heart skip a beat. He felt incredibly uncomfortable, and a sense of powerlessness rose from the depths of his heart.
As the head of the Uchiha clan, he watched helplessly as his clansmen became like this, as they died on the battlefield and his children turned into this state.
Uchiha Takashi turned his face away; he couldn't bear to see such a miserable and lonely sight, especially the child—a child with a bright future shouldn't be like this.
