Insights and Gains 1

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

Seeing Uchiha Setsuna appear out of nowhere, Uchiha Fugaku couldn't help but jump.

"Great Elder, do you have to sneak around like that? You know you could scare someone to death!"

Hearing Uchiha Fugaku's words, Uchiha Setsuna gave an awkward smile.

Uchiha Fugaku then realized that Uchiha Setsuna had come to see him about something, so he asked,

"Great Elder, what is it?"

At Uchiha Fugaku's question, Uchiha Setsuna asked expectantly,

"I've heard for a long time that Senjutsu greatly boosts one's strength. Will the other Uchiha clan members get a chance to learn it?"

Hearing that this was all he wanted to ask, Uchiha Fugaku was at a loss for words.

He'd thought something major had happened, but all Uchiha Setsuna wanted to know was whether Senjutsu could be learned.

Still, Uchiha Fugaku had planned to have the entire clan practice Sage Mode anyway. Telling Uchiha Setsuna early so he could spread the word in secret was a good idea.

With that in mind, Uchiha Fugaku answered directly,

"Anyone can learn it. I created Senjutsu based on Uchiha blood."

"As long as they have Uchiha blood and possess chakra, they can learn it."

Hearing this, Uchiha Setsuna grew excited.

This was Senjutsu, after all. If the entire clan could learn it, what family in the Shinobi World could stand against the Uchiha?

After that question, Uchiha Setsuna continued,

"Clan Head, when can you start teaching the clan members Senjutsu?"

Uchiha Fugaku thought for a moment before answering,

"Let them know in secret. I'll teach Senjutsu three days from now, but only to those who complete their daily Taijutsu training."

Having received the answer he wanted, Uchiha Setsuna happily left to take care of it.

Just as Uchiha Setsuna was about to leave, Uchiha Fugaku thought for a moment, then called after him,

"Great Elder, make sure to keep this secret. Don't let anything slip before they've learned it. I want to give the whole village a big surprise."

At Uchiha Fugaku's command, Uchiha Setsuna immediately replied,

"Don't worry, Clan Head. I know what to do."

Back home, Uchiha Fugaku began sorting through what he'd gained from his latest enlightenment.

To be honest, the gains from this enlightenment had far exceeded his expectations.

Not only had Uchiha Fugaku created three versions of Sage Art: Sage Mode, surpassing even his expectations, but he'd also created several Senjutsu techniques to increase his own strength.

One example was Sage Art: Unhearable, which he'd just used to intimidate Sarutobi Hiruzen and Hyuga Hiashi.

He had created it by adapting the principles behind the mental attacks in the Qi Refining Technique into a ninjutsu. Sage Art Chakra emitted by Sage Mode carried mental energy without a sound, then delivered an impact through sound.

As for this ability, Uchiha Fugaku had created it specifically to deal with the Death God.

The reason was a sudden thought during his enlightenment: Would Sarutobi Hiruzen try to use the Sealing Jutsu: Dead Demon Consuming Seal to take him down with him?

Although he had the Mangekyou Sharingan ability Indomitable as a safeguard, Uchiha Fugaku took every thought that arose during his enlightenment extremely seriously.

After all, if the thought had occurred while he was in a state of enlightenment, that meant there was a real chance it could happen.

Besides Unhearable, Uchiha Fugaku had also created three more Senjutsu techniques: Invisible, Sage Fire Sun Flame Seal, and Sage Susanoo.

Sage Art: Invisible was based on the principles of Sharingan Genjutsu.

He attached Sharingan Genjutsu to his unique Sage Chakra Cloak, affecting everyone who had ever watched him from the shadows.

It was like turning himself into a Sharingan with no blind spots. Just when an opponent thought they could avoid the Genjutsu by not meeting his gaze, he could give them a surprise.

He could even use it while traveling around the Shinobi World. As long as he maintained Sage Mode, no one would know where he went. After all, anyone who observed him would be affected by the Genjutsu and lose their memories.

Sage Fire Sun Flame Seal was a Senjutsu technique created by drawing on Amaterasu's effects and incorporating the theories of the Qi Refining Technique.

It changed flames normally produced by chakra into flames that ignited Natural Energy in the Shinobi World through Senjutsu Chakra marks.

Of course, to keep the whole Shinobi World from going up in flames, Uchiha Fugaku had put limits on the technique. Once the Senjutsu Chakra in a mark ran out, or the caster dispelled the technique, the Natural Energy flames would go out.

This technique was meant to deal with people who, like him, could use Senjutsu. The Sage Fire Sun Flame Seal was even more powerful when used against someone who possessed Senjutsu, burning them to ashes before they could fight back.

The last technique was Sage Susanoo.

During his enlightenment, Uchiha Fugaku had also studied the Uchiha's Sharingan in the time he had left after creating his Senjutsu.

He had to admit, the changes that came with the Sharingan's evolution were astonishing. Its power could form an ability in response to its owner's wishes, then make that ability permanent.

Although Uchiha Fugaku could no longer change his own ocular abilities, he had thoroughly mastered Susanoo.

Now, when he used his Sharingan to expend ocular power and summon Susanoo, he could change its form without affecting its strength. He could also add Senjutsu energy to bolster its power and strengthen its defense—enough to withstand even attacks beyond Senjutsu.

Besides those techniques, Uchiha Fugaku had ultimately created three versions of Sage Art: Sage Mode.

The first was a version exclusive to him.

First, this version completely transformed Uchiha Fugaku's body, allowing him to fully adapt to Natural Energy. That meant anyone who mastered it could absorb Natural Energy from the Shinobi World and enter Sage Mode at any time, remaining in that state until their chakra ran out. Even then, they could use Natural Energy to enhance their bodies in Taijutsu combat. The reason they could only use Taijutsu was that Uchiha Fugaku still had no way to release Natural Energy externally, due to its properties.

However, Uchiha Fugaku believed that if he could draw new knowledge about cultivation techniques from the system, he would sooner or later develop a way to use it.

Next was his Sage Chakra Cloak. The Sage facial markings were too ugly (except for Uzumaki Naruto, since he was the protagonist), so an energy cloak looked much cooler. It could also strengthen his defense.
