After Naruto returned to his rented house, he was in a very good mood.
On Hinata's side, the old man still refused the idea of marriage, saying that she was the future head of the Hyuga Clan. But Naruto understood that it was only a matter of time.
After all, Hyuga Hiashi himself was strongly against the branch family system.
Naruto didn't mind protecting his "future wife."
In fact, the name Uzumaki Naruto originally came from his mother's surname. In the Hokage world, commoners and women usually didn't have family names.
Even someone noble like Tsunade didn't inherit the Senju surname.
So the Uzumaki name didn't really bring any benefits, except attracting hatred from enemy villages, because the Uzumaki Clan was famous for its sealing techniques.
The reason Naruto hadn't asked Might Guy for training before was simple—he didn't have enough money.
Physical training required medicine to heal the body after intense workouts. Without it, hidden injuries would build up and slow down growth.
In the end, being only 1.4 meters tall at age twelve would look pretty pitiful, and heavy training might even leave Naruto disabled.
Even though height wasn't always important for ninja missions, Naruto still wanted to reach at least 1.8 meters. Maybe not as tall as the Raikage, but definitely not shorter than that.
As for the Nine-Tails' chakra healing, it worked somewhat like Tsunade's Mitotic Regeneration.
Simply put, it accelerated cell healing. Because Naruto was young and had Ashura's Yang chakra, there were almost no side effects.
Even so, Naruto preferred to use it only when necessary.
Now, with the support of the Hyuga Clan, Naruto no longer needed to worry about money.
So when Naruto appeared in front of Might Guy wearing a black training outfit—the same type Kakashi once wore while training Sasuke—Guy immediately hugged him and shouted:
"Youth!! Let's sweat as we run toward the sunset!"
From that day on, at the edge of Konoha, besides the "Blue Beast" who trained loudly every day, another child appeared, gritting his teeth and pushing himself to the limit.
Naruto's training was mocked by many civilians and even some low-level ninja.
After all, the Hokage world was built around ninjutsu.
In their eyes, no matter how strong your physical skills were, you couldn't compete with a ninja who used chakra.
As long as they added chakra to their fists, they believed no one could defeat them.
Because of this belief, even though Might Guy was famous for his taijutsu, he wasn't very respected.
Just looking at his nickname—"Blue Beast"—you could tell it wasn't meant as praise.
But Naruto didn't care.
He knew that strong physical training could greatly increase his power.
Even without anything else, mastering the Eight Inner Gates would be enough to silence those who mocked him.
Guy himself was just an ordinary man, yet he almost reached the Six Paths level with pure effort. Naruto didn't understand how some fans underestimated that.
After all, Naruto could become a fighter even stronger than the Six Paths level.
If the Eight Inner Gates were used at that level, he might defeat enemies in seconds—even someone like Uchiha Madara.
Combined with the healing power of the Nine-Tails' chakra and Ashura's chakra, Naruto might even be able to use Night Guy without dying.
Maybe when he reached Six Paths level in the future, he could truly use Night Guy safely.
Thinking about this, Naruto suddenly felt that wearing the tight training clothes wasn't so embarrassing anymore.
He had changed from a lazy otaku into a true training maniac.
The Naruto who once only ate and slept now trained endlessly under Might Guy's guidance.
Every day he pushed himself until he fainted, and someone would carry him back to the Hyuga residence.
Hyuga Hiashi would place Naruto into a special healing bath to repair the damage caused by the intense training.
Thanks to the Hyuga clan's medical resources, the overtraining that would normally damage the body instead strengthened Naruto's growth.
Under the effect of the healing baths, Naruto not only avoided injury but also developed physically faster than children his age.
After more than two years of training, Naruto—now only six years old—was already close to the height he originally had at age twelve.
His height had reached an amazing 1.4 meters.
In the Hokage world, many children from ninja families actually had weaker bodies because of early training.
The original Naruto was only about 1.45 meters when he graduated.
During these two years, besides physical training, Naruto also kept defeating Sasuke.
At the same time, he secretly observed Uchiha Itachi teaching Sasuke and took notes on the Uchiha shuriken techniques.
After all, the Uchiha clan was famous for their mastery of shuriken.
And in this quiet period of training,
Naruto finally reached the moment to enroll in the Ninja Academy…
