Seeing the two looking shocked, Naruto asked with a smile, "What? You don't believe me? If you don't, I can have my dad talk to you sometime."
Shisui: ...
Itachi: ...
Hearing Naruto say this, Shisui quickly waved his hand, "Uh... let the Fourth Hokage rest in peace! No need to send me dreams... I'm afraid of ghosts."
Naruto gave Shisui a speechless look, not expecting this guy to be afraid of ghosts.
"Don't worry... my dad isn't dead! He's just sealed away right now, and he'll be unsealed in a few days!"
If Naruto being the Fourth Hokage's son had shocked them, the news that the Fourth Hokage was still alive completely petrified them on the spot.
"The Fourth Hokage... is still alive?"
"Konoha's Yellow Flash... is still alive?"
The two murmured simultaneously.
The Fourth Hokage's image among all the Ninja of Konoha was simply too perfect, too great.
Especially among young Ninja, he was practically a national idol.
Plus, with the Achievements of sealing the Nine-Tailed and saving Konoha, if the people of Konoha knew the Fourth Hokage was still alive, they would definitely go crazy!
"Um... Naruto, can we really see the Fourth Hokage?"
Shisui still asked, somewhat disbelieving.
Seeing Shisui's expression, Naruto smiled and said, "Of course you can."
As he spoke, Naruto checked the time on his phone, then continued, "You'll probably see him in about ten days!"
"Alright... let's not talk about him for now. We can discuss it when you meet him in a few days!"
"Let's talk about you two instead. You should know, right? Excessive use of the Mangekyo will lead to declining eyesight and eventually even blindness!"
Itachi and Shisui exchanged glances, then Itachi nodded and said, "We know. We found out right after we awakened the Mangekyo and used it!"
"And you still do this?"
Naruto still valued Itachi and Shisui highly. He even planned to get some Hashirama Cells from Orochimaru to inject into them, so they wouldn't be dragged down by the Mangekyo.
Although Hashirama Cells were quite dangerous, Naruto believed that with Grey Wolf around, everything would be fine!
Hearing Naruto's question, Shisui and Itachi exchanged smiles.
"Don't worry, Naruto! The eye problem is no longer an issue since we awakened Nen and learned 'En'!"
Shisui's words made Naruto pause, and then he realized how they had solved the problem of eye strain.
By condensing Nen Aura in their eyes using 'En'.
No matter what, Nen Aura was life energy. Controlling high-concentration life energy to protect their eyes was indeed a good method.
In fact, using Nen to protect their eyes had a similar effect to fusing with Hashirama Cells.
The purpose of fusing with Hashirama Cells was for that immense life energy.
And Nen Aura was also life energy; although not as vast as Hashirama Cells, it was very pure and controllable!
As long as their Nen wasn't depleted, they could use the Mangekyo without any problems!
"It really is a good method!"
Naruto couldn't help but exclaim.
"Nen is indeed a very versatile ability. Although its power in the early stages isn't as great as Ninjutsu released with Chakra, its functionality is much higher than Chakra!"
These past few days, besides teaching the children at the base, Itachi had been cultivating Nen and learning related knowledge.
Although it had only been seven days, Itachi and Shisui had already proficiently mastered 'En,' 'Hatsu,' 'Ren,' and 'Zetsu.'
While they hadn't yet developed their own abilities, they already had a good idea of what they would be!
Learning that Itachi and Shisui had mastered the basics of Nen Ability in just seven days, Naruto couldn't help but sigh with emotion.
"Truly worthy of being called geniuses!"
"Hehehe," Shisui chuckled and said, "Actually, the main reason we were able to master the basics of Nen so quickly is because our control over Chakra is relatively strong. Now it's just a different energy system! The control is pretty much the same!"
After understanding Shisui and Itachi's Nen training, Naruto went to find Grey Wolf.
Because Naruto had jumped out the back window of the Office to find Itachi and Shisui earlier, he hadn't noticed the changes at the front entrance.
When Naruto walked out the front entrance, he was completely stunned.
First, what greeted his eyes were rows of brick houses, neatly arranged on both sides of the road.
Although these brick houses weren't yet completed, their basic structure was already visible.
And countless bricks were stacked on both sides of the road.
Besides that, there were strange robots and villagers carrying various building materials, walking back and forth.
"Holy crap... Grey Wolf is undertaking a massive project!"
Hearing Naruto's words, Shisui came up beside him and said, "I didn't expect you to be so amazing, Naruto!"
"Huh? Me?"
Naruto was a bit confused. What did all this have to do with him? Wasn't Grey Wolf the one doing all this?
Just then, Naruto inadvertently saw Itachi walk over to Shisui and gently poke him.
Itachi's action instantly made Shisui pause, and then, as if remembering something, he quickly apologized to Naruto.
"Um... Naruto, I didn't mean to, I know Grey Wolf is your good friend and not..."
Before Shisui could finish his sentence, he was interrupted by Itachi's cough, "Cough cough... Shisui, say less!"
Naruto: ...
Seeing the two, Naruto finally understood what was going on.
They still thought Grey Wolf was his other personality.
"I'm not schizophrenic, and I'm not mentally ill," Naruto said through gritted teeth.
"Ah, yes, yes, yes... you're not schizophrenic."
"Mhm, mhm, mhm, yes, yes, yes..."
Naruto: ...
Seeing this, Naruto simply gave up on explaining.
Ignoring the two of them, Naruto found Grey Wolf.
Grey Wolf was still working, but he wasn't making water heaters or flush toilets as previously mentioned; he was making robots.
"I say... Grey Wolf, you don't need to make this project so big, do you?"
Grey Wolf, who was working intently, looked up at Naruto, then said, "Those things you mentioned can't be realized with the current buildings here, so I had no choice but to take on the construction here as well!"
After speaking, Grey Wolf pointed to a machine that was running nearby. Next to the machine, two villagers were throwing various odds and ends into it.
There were stones, rotten wood, scrap metal, and even dirt.
These things were thrown into the machine's funnel, and after some operation, good-looking steel was extruded from the other side.
This unscientific scene unfolded right before Naruto's eyes.
"Is this the material converter?"
Naruto asked.
"That's right... With this thing, construction is much easier!"
Naruto: ...
