Special Tutoring

The second version, the Genius Version, while not significantly different from the standard Sage Mode in terms of functionality—as both ultimately serve to enhance ninjutsu and the physical body—differs greatly in other aspects.

First, it utilizes the Uchiha Bloodline to lower the difficulty of cultivation and eliminates the risk of petrification during the process.

Second, cultivating this version of Sage Mode does not result in alienation or the appearance of sage markings upon activation. Naturally, there is no energy cloak either, but a mark will appear on the user's back. Furthermore, since the mark appears on the back, it remains hidden even during combat, making it easy to deceive opponents and defeat them with ease.

As for the shape of the mark, Uchiha Fugaku designed it directly as the Uchiha Clan crest to save himself the trouble; he wouldn't be using it himself anyway.

The final version is the ultimate simplified version, also known as the Common Version.

It possesses only one-tenth the capability of the standard Sage Mode, and thus cannot be compared to Uchiha Fugaku's own Sage Mode.

However, its advantage lies in its simplicity; as long as one persists, they will eventually succeed in cultivation, though those with greater aptitude will naturally progress faster.

Next is Uchiha Fugaku's optimization of this entire Sage Mode system.

One aspect is the aforementioned optimization for descendants.

The other is the addition of a bloodline restriction while lowering the difficulty: only those possessing the Uchiha Bloodline can sense natural energy through this method and begin the adaptation process, eventually generating Sage Chakra through a special technique once they have fully adapted to the natural energy.

As for outsiders, the only result of attempting to cultivate it is petrification.

During the final remaining time in Enlightenment Mode, Uchiha Fugaku began to ponder how to solve the problem of his own low chakra reserves.

Although Uchiha Fugaku had increased his chakra somewhat through research into the Senju Bloodline, he was still a little distance away from reaching "Chakra-ton" levels.

After all, it is common knowledge that the Senju Bloodline and the Hashirama Bloodline are two different things.

But even after the Senju Bloodline reached its limit, he could not think of a particularly good solution, even while in Enlightenment Mode; after all, Uchiha Fugaku's foundation and body were limited.

Although Enlightenment Mode allows one to create and eventually solve problems starting from the very basics, it was clear that Uchiha Fugaku did not have that much time or Enlightenment Tea.

Otherwise, the aforementioned Sage Arts and Sage Mode would not have been derived from the Qi Refining Manual and ninjutsu, but rather Uchiha Fugaku would have directly forged a new longevity-cultivation system.

However, after some thought, Uchiha Fugaku actually found a way that wasn't quite a solution.

That is, to open the Dantian just like in the Qi Refining Manual, thereby expanding his own chakra storage.

It is similar to the Yin Seal from the original work, only hers is located on her forehead, while his would be at the Dantian.

Unfortunately, this ninjutsu was only developed into a defective product before Uchiha Fugaku completely exited Enlightenment Mode.

Although it was a pity, Uchiha Fugaku was naturally unwilling—or rather, it wasn't worth it—to use another leaf of Enlightenment Tea for just one ninjutsu.

After all, as long as he lets most of the clan learn Sage Art and their strength surges, he will gain more opportunities for lucky draws. Who knows when Uchiha Fugaku might obtain even stronger and more powerful knowledge through a draw?

Such as higher-level cultivation techniques, high-martial arts, or true spells...

Perhaps by then, Uchiha Fugaku will be able to rely on the ninjutsu created through Enlightenment Tea to step into the Six Paths level or become an existence above the Six Paths, even without becoming the Ten-Tails Jinchuriki.

Moreover, his current chakra is temporarily sufficient; even using Kakashi as a unit of measurement, he has quite a few "Kakashis" worth.

Note: You are a "one-second man" capable of bursting with power comparable to the Six Paths level.

Looking at his panel, Uchiha Fugaku naturally gained a clearer understanding of his own strength.

However, Uchiha Fugaku did not agree with the system's evaluation. A "one-second man"? You must know that my, Uchiha Fugaku's, chakra volume is comparable to many Kakashis. I'm a one-second man? Then where does that put Kakashi, system? That's a guy who can hold a conversation while wielding a Chidori, alright?

After organizing his gains, Uchiha Itachi and Izumi Uchiha, having been notified by Uchiha Fugaku in advance, returned home early.

As his own fine son and his personally designated future daughter-in-law, Uchiha Fugaku naturally chose to give them some special attention.

"Father."

("Clan Leader.")

Hearing how the two addressed him, Uchiha Fugaku smiled and said to Izumi Uchiha.

"Izumi, there are no outsiders here, calling me Clan Leader is too distant."

"Besides, the fact that you are Itachi's girlfriend is something both I and his mother, Mikoto, have accepted."

"Although you aren't married yet, it won't be long, so when there are no outsiders, just call me Father, just like Itachi does."

Hearing this, Izumi Uchiha blushed again and lowered her head, not daring to look at Uchiha Itachi.

Why would Clan Leader Fugaku say that in front of Itachi? What if Itachi gets angry?

Unlike Izumi Uchiha, Uchiha Itachi was completely bewildered.

When did this even happen?

Although he and Izumi were close, they hadn't exactly established a boyfriend-girlfriend relationship, had they?

And why, from his father's perspective, were they already on the verge of getting married?

Wasn't this progress a bit too fast?

However, Itachi naturally dared not contradict Uchiha Fugaku's words.

He could only accept it by default, though it didn't seem like such a bad thing; after all, he didn't dislike this girl who could read his subtle thoughts and truly liked him.

(Itachi: Although I don't quite agree, it's actually quite nice.)

Afterward, Izumi Uchiha stole another glance at Uchiha Itachi's expression.

Finding that Uchiha Itachi showed no signs of opposition, she finally whispered, "Father," under Uchiha Fugaku's expectant gaze.

Hearing this "Father," Uchiha Fugaku couldn't help but feel significantly more cheerful, while Uchiha Itachi's expression became somewhat complicated.

Uchiha Fugaku did not tease the two for long, however, before saying, "I called you here today because there is an important matter to discuss."

"As the geniuses of the clan, and as my son and future daughter-in-law, I have decided to teach you both Sage Mode in advance."

Sage Mode? Was it the same Sage Mode as the First Hokage?

Upon hearing "Sage Mode," Izumi Uchiha was shocked beyond measure, as she had been helping Uchiha Fugaku process documents at the Military Police Force before coming here and had no knowledge of this.

Seeing the confusion on Izumi Uchiha's face, Uchiha Fugaku activated his exclusive Sage Mode.

As the senjutsu chakra condensed, a special red sage cloak appeared on Uchiha Fugaku's body; naturally, he did not exert the power of the Sage Mode, so it had no effect on the two of them.

Seeing this appearance, it was the first time Izumi Uchiha felt that her clan leader could actually look so cool.

However, Izumi Uchiha secretly glanced at Uchiha Itachi again, thinking to herself, Itachi is still the coolest in my heart.

Although Uchiha Itachi remained expressionless on the surface, his eyes flickered with anticipation.

After all, who wouldn't want such a cool and powerful ability?
