Enlightenment and Harvest

After seeing off Sarutobi Hiruzen, Hyuga Hiashi, and Might Guy, Uchiha Setsuna appeared behind Uchiha Fugaku like a ghost.

Uchiha Fugaku was startled by the sudden appearance of Uchiha Setsuna.

"Great Elder, please stop being so stealthy. Don't you know that scaring people can literally kill them?"

Hearing Uchiha Fugaku's words, Uchiha Setsuna smiled with a hint of embarrassment.

Uchiha Fugaku realized that Uchiha Setsuna must have come to him for a reason, so he asked directly.

"Great Elder, is there something you need?"

Upon hearing Uchiha Fugaku's inquiry, Uchiha Setsuna asked with anticipation.

"I have long heard that Sage Art provides a massive boost to strength. Is there any chance for other Uchiha clansmen to learn it?"

Hearing that the question was only this, Uchiha Fugaku was left speechless.

He had thought something major had happened; he didn't expect it was just a question about whether Sage Art could be cultivated.

However, since his original plan was for the entire clan to cultivate Sage Mode, telling him in advance so he could spread the word secretly was not a bad idea.

Thinking of this, Uchiha Fugaku spoke directly.

"It can be cultivated, because I created this Sage Art based on the foundation of the Uchiha bloodline."

"As long as one possesses the Uchiha bloodline and has chakra, they can cultivate it."

Hearing this, Uchiha Setsuna couldn't help but become excited.

One had to realize this was Sage Art. If the entire clan could cultivate it, there would be no family in the ninja world capable of competing with the Uchiha.

However, following this, Uchiha Setsuna continued to ask.

"Clan Head, do you know when we can begin teaching the clansmen Sage Art?"

Uchiha Fugaku thought for a moment and said.

"Notify them secretly. I will teach the Sage Art in three days, but it is limited to those who complete their daily taijutsu training tasks."

Having received the answer he wanted, Uchiha Setsuna left in high spirits to handle the matter.

Just as Uchiha Setsuna was about to leave, Uchiha Fugaku thought for a moment, then called him back and said.

"Great Elder, remember to maintain strict confidentiality. Do not let word leak out before they have successfully cultivated it; I want to give the entire village a big surprise."

Hearing Uchiha Fugaku's order, Uchiha Setsuna immediately replied.

"Rest assured, Clan Head, I understand these matters."

Returning home, Uchiha Fugaku began to organize the gains from this enlightenment.

To be honest, the gains from this enlightenment far exceeded Uchiha Fugaku's imagination.

Not only did Uchiha Fugaku complete the creation of three versions of Sage Art: Sage Mode, which exceeded his own expectations, but he also created several other Sage Arts to increase his strength.

For example, the Sage Art: Unhearable, which he had just used to intimidate Sarutobi Hiruzen and Hyuga Hiashi.

This was created by Uchiha Fugaku using the principles of spiritual attacks from the Qi Refining Technique combined with ninjutsu. It uses the Sage chakra emitted during Sage Mode to silently carry spiritual power, completing the impact through sound.

As for this ability, it was created specifically for Uchiha Fugaku to deal with the Reaper.

The reason was a sudden thought during his enlightenment—would Sarutobi Hiruzen try to use the Sealing Technique: Reaper Death Seal to take him down?

Although he possessed the Mangekyo ocular technique Indomitable as a precaution, Uchiha Fugaku took every thought during his enlightenment extremely seriously.

After all, if such a thought arose while he was in a state of enlightenment, it naturally indicated the possibility of such an event occurring.

Besides Unhearable, Uchiha Fugaku also created two other Sage Arts: Invisible, Sage Fire Sun Flame Seal, and Sage Susanoo.

Sage Art: Invisible utilized the principles of Sharingan genjutsu.

By attaching Sharingan genjutsu to his unique Sage Chakra Cloak, he could influence everyone who observed him in secret.

It was equivalent to turning himself into an all-encompassing, blind-spot-free Sharingan. When an opponent thought they could avoid the influence of genjutsu simply by not making eye contact, he would give them a surprise.

Furthermore, it could be used while traveling through the ninja world. As long as he maintained Sage Mode, no one would be able to know where he went, as anyone who observed him would be affected by the genjutsu and lose their memory.

As for the Sage Fire Sun Flame Seal, it was a Sage Art created by referencing the effects of Amaterasu and adding the theories of the Qi Refining Technique.

It transformed flames originally produced by chakra into a method of igniting natural energy within the ninja world through Sage chakra seals.

Of course, to avoid setting the entire ninja world ablaze, Uchiha Fugaku placed restrictions on this ninjutsu; once the Sage chakra in the seal was exhausted or the caster dispelled the technique, the natural energy flames would extinguish.

This was specifically designed to deal with others who possessed Sage Art, as the Sage Fire Sun Flame Seal was even more powerful when used on someone who possessed Sage Art, causing those who knew Sage Art to be burned to ashes without any power to resist.

Finally, there was Sage Susanoo.

During his state of enlightenment, in the spare time after creating the Sage Arts, Uchiha Fugaku also conducted research on his own Sharingan.

One had to admit the wonder of the Sharingan during its evolution; it was actually able to generate and solidify abilities according to the owner's will based on the miraculous changes during the promotion.

Although Uchiha Fugaku no longer had a way to change his own ocular techniques, he had fully comprehended the Susanoo.

Uchiha Fugaku was now able to alter the form of his Susanoo while manifesting it through the ocular power of his Sharingan, all without compromising its potency. He could also infuse it with Sage Art energy to augment its power and bolster the Susanoo's defensive capabilities, making it strong enough to withstand even attacks that surpassed the level of Sage Arts.

Beyond these few Sage Arts, there were the three versions of the Sage Art: Sage Mode that Uchiha Fugaku had ultimately created.

The first version was his own exclusive iteration.

First and foremost, this version thoroughly remodeled Uchiha Fugaku's body, allowing him to fully adapt to natural energy. This meant that, as a successful practitioner, he could absorb the natural energy of the ninja world to enter Sage Mode at any time, and he would not revert as long as his chakra remained unexhausted.

Even after his chakra was completely depleted, he could still utilize natural energy to reinforce his body for taijutsu combat. As for why he was limited to taijutsu, it was simply due to the nature of natural energy; Uchiha Fugaku had not yet found a way to project it externally for use.

However, Uchiha Fugaku believed that as long as he could draw new cultivation-type knowledge through the system, he would sooner or later develop the corresponding methods to utilize it.

Next was his Sage Chakra Cloak; after all, the Sage facial markings were far too unsightly (with the exception of Uzumaki Naruto, who was the protagonist, after all), and an energy cloak was much cooler, not to mention it further enhanced his defensive capabilities.
