For the next period of time, Naruto did not go to the Third Training Ground to train with Kakashi and Might Guy again, but stayed at home, or more precisely, stayed in the Sealed Space to learn Four Symbols Sealing with Minato Namikaze.
It took a full week for Naruto to roughly master the Four Symbols Sealing. The practice of Sealing Technique was by no means easy, even far more complex than ordinary Ninjutsu. This was a technique with very miraculous effects, capable of even dimensionally compressing objects, just like the Eight Trigrams Sealing on Naruto's stomach, which had already formed its own space within.
This was still with Minato Namikaze as a teacher. Due to Uzumaki Kushina, Minato Namikaze's Sealing Technique level was also quite high. After all, the Nine-Tailed then was not as docile as it is now. If there was any runaway situation, it could basically only be sealed by Minato Namikaze.
I remember in the original work, Minato Namikaze was even directly pierced through by the rampaging Uzumaki Kushina, and yet he still managed to seal Kurama back in the end.
At the same time, coupled with Uzumaki Naruto himself being of Vortex Clan bloodline, he inherently possessed extremely high Sealing Technique talent. With both factors combined, his progress in Sealing Technique cultivation could be described as rapid, which is why he was able to largely master the Four Symbols Sealing in just one week.
As for why Naruto in the original work didn't know Sealing Technique, the current Naruto is also not clear. Most likely, it was too severely affected by Ashura's Chakra, only knowing how to make Rasengan.
In the room, Naruto looked at the comic book on the table, felt the sealing mark on his body, and directly pressed his hand on the comic book. Circles of Four Symbols Sealing patterns spread out from Naruto's palm, completely enveloping the entire comic book. With a "bang" sound, amidst a puff of smoke, the comic book on the table directly disappeared and then appeared out of thin air in Naruto's Sealed Space.
"Success?!"
Minato Namikaze's eyes lit up with surprise, and he raised his hand to catch the comic book falling from the air.
"Hmph, that really is an annoying technique."
Kurama watched this scene from the side with ill intent, snorting unhappily, after all, this was the technique that had sealed it for decades.
"Haha, Kurama, now that Naruto has learned this Sealing Technique, we won't be too bored in the Sealed Space."
Minato Namikaze placed the comic book in front of Kurama. He also learned Kurama's name from Naruto. Although he had a deep hatred for Kurama, they were now staying together in the Sealed Space, and perhaps they would stay for decades, while also relying on the other's Chakra to sustain their lives, so he had no choice but to get along with the other party for now.
And when Kushina comes out later, then two people will rely on Kurama's Chakra to sustain their lives. It's good to ease the relationship now.
"Hmph, this old man doesn't need such boring things." Kurama huffed somewhat tsundere-like.
"Kurama, you're still so tsundere."
Naruto's figure also appeared in the Sealed Space.
"Brat!" Kurama roared in exasperation.
"Naruto, congratulations, I didn't expect you to learn the Four Symbols Sealing so quickly." Minato Namikaze walked over with a genuine smile, his eyes filled with relief. If he could learn Flying Thunder God this quickly too, he would be even more relieved.
For his child to fully inherit his and his wife's talents is undoubtedly one of the most gratifying things for a father.
"That's also thanks to Fourth Hokage teaching so well." Naruto also politely thanked him.
Naruto's politeness did not surprise Minato Namikaze. Being able to get along like this now was already very good for him.
"This is mainly because of your good talent, Naruto. Should we start practicing Flying Thunder God now, or familiarize yourself with the Four Symbols Sealing for a while first?"
Naruto thought for a moment and asked, "The training for Flying Thunder God should be much more difficult than Four Symbols Sealing, right?"
Minato Namikaze also nodded, his expression serious, and said, "Flying Thunder God is a Space-Time Ninjutsu. Besides requiring great effort, it also depends on whether the practitioner possesses talent in space-time."
"Then let's learn it later. Konoha might have a big event these few days." Naruto glanced at Kurama, who was secretly peeking at the comic book, and thought, I can also let Uzumaki Kushina out in a while. I still need to learn the Vortex Clan's Adamantine Sealing Chains from her.
"Big event? Is something big going to happen in Konoha again?" Minato Namikaze's expression was somewhat complex. Although he currently had no good feelings for the current Konoha, he was still Konoha's former Hokage. When he heard this news, his mood was inevitably a bit complicated.
Naruto also showed a mysterious smile, "Fourth Hokage, you will soon see the hypocritical appearance of Konoha's higher-ups with your own eyes."
More than a month had passed, and Hiruzen Sarutobi still hadn't found the person who invaded the Village. He was probably starting to suspect Uchiha Shisui, after all, the only witness to the invader was Uchiha Shisui, and it was well known that in Konoha, Uchiha was not trusted.
When the Hyuga Clan closes their Byakugan, he can begin to arrange his plan. Setting up an inescapable net near the Uchiha Clan Grounds will always give him an opportunity. A pair of Mangekyo is worth it.
"Was I really wrong?"
Naruto looked at Minato Namikaze, who was starting to doubt life again, and said nothing more. He was indifferent to Minato Namikaze; he harbored no hatred, but he certainly wouldn't regard him as his father. This was unavoidable, after all, he wasn't his real father. Their current relationship was quite good.
"Hmm?" Naruto's expression, deep in thought, changed slightly, and he disappeared directly from the Sealed Space.
Minato Namikaze, still in self-isolation, had no reaction to this. Kurama, who was secretly reading the comic book, merely stole a glance, and its actions of reading the comic became a bit more open.
Not long after Naruto's consciousness emerged, there was a knock at the door.
Time rewound to an hour ago.
Inside the Third Training Ground, Might Guy was training alone.
Sprinting, handstands, push-ups, sit-ups, punching, kicking—after silently completing all the exercises, Might Guy finally couldn't bear it anymore.
For some reason, Naruto and Kakashi hadn't come to the training ground for a week. He didn't know Naruto's home address and couldn't find Kakashi, so he had no idea about their situation. Had they gone on some secret mission, or were both of them sick at home with no one to take care of them?
"No, I must go ask Lord Third Hokage for clarification!"
As soon as he thought of it, he acted immediately. Might Guy stood up straight from the ground and ran towards the Hokage Building.
It just so happened that Hiruzen Sarutobi had also noticed Naruto's abnormality these past few days. Although he could observe through the Byakugan, he could only see Naruto spacing out and had no idea of the actual situation. So, he told Might Guy Naruto's home address, and also informed Might Guy of Kakashi's current location and mission, asking them both to go and check the specific situation.
Might Guy immediately ran out excitedly and found Kakashi, who was hiding in a tree secretly reading an adult comic book, next to Naruto's residence.
"Why are you here?"
Kakashi looked expressionlessly at the suddenly appearing bushy brows.
"Kakashi, my dear friend, we haven't competed in a week."
Might Guy revealed his signature teeth, "Today, let us have a long-awaited competition."
"The content of the competition will be to see who finds out why young Naruto hasn't been leaving his house first!"
