5: Levels

Yuya eventually stole the book and took one random book, and asked to borrow the book, then Yuya went back home.

Upon arriving home, Yuya immediately opened the small book.

[There are Three Forbidden Jutsu, which have been Modified]

[Space-Time Jutsu: Element Storage]
[Someone can store various things in the dimensional space created by the user, living creatures can also be stored in the Space Jutsu, but doing so consumes more Chakra]

[Combination and Separation Jutsu: Life Material]
[Can combine something, whether it's Jutsu or Objects, and produce something new, can also separate them again, consuming quite a lot of Chakra, but the results are worth it]

[Information Jutsu: Latest News]
[Will provide various up-to-date information, which is around the user, whether it's information from someone's memory, past events, or events from the future, although very random, but the information is truly accurate]

"What?" Yuya was surprised by all of this, however, if there were strange Jutsu like that, it would cause chaos, whether Yuya liked it or not, he wondered who actually created the book.

Although initially hesitant, Yuya eventually tried it, although Yuya always failed, but it turned out that it was because Yuya did not have enough Chakra, and did not have adequate experience, therefore Yuya continued to practice.

Until the whole day, the next day Yuya returned the borrowed book, except for the small book, relying on the small book, Yuya practiced very hard, because the three Jutsu did not require Hand Seals, it was much easier for Yuya.

...

Day after day, Yuya passed by practicing, with hard training, morning, noon, afternoon, night, making Yuya stronger, because his experience was still very lacking in battle, Yuya finally used Shadow Clone Jutsu, which was a characteristic of Naruto.

Shadow Clone Jutsu is special, because the Jutsu requires a lot of Chakra, but in return, it will give the user experience from the created Clone.

Yuya also learned Body Flicker Jutsu, as well as Transformation Jutsu, and Replacement Jutsu.

Previously, Yuya did not practice with various Jutsu, because his Chakra at that time was not adequate, but now he has a lot of Chakra.

Yuya also trained his physique harder, which made his muscles torn, but it would make his muscles stronger.

Therefore, Yuya did extreme training that was very hard, when Yuya reached the age of Ten Years, his mother taught Yuya how to make Pill Medicine, and concoct Herbal Medicine.

Although initially difficult, but over time it became easy and enjoyable, Yuya also started practicing cooking, because it might be needed someday.

Yuya trained very hard, every day he only practiced, practiced, and practiced, without any days off, Yuya practiced every day.

Thus, Yuya finally became strong enough, although he knew that he was still not strong enough at the level of Hokage, at most only at the level of Elite Chunin or Beginner Jonin, in terms of Raw Power without experience.

Although Yuya did not know, in this period whether the Levels were still the same, as in the Great Ninja Era before, which consisted of Ordinary Humans, Ninja Academy Students, Beginner Genin, Ordinary Genin, Experienced Genin, Beginner Chunin, Ordinary Chunin, Experienced Chunin, Special Chunin, Elite Chunin, Beginner Jonin, Ordinary Jonin, Experienced Jonin, Special Jonin, Elite Jonin, Beginner Kage, Ordinary Kage, Experienced Kage, Special Kage, Elite Kage, and finally God.

Although not like that, but that is the most appropriate according to Yuya, however, even though someone is a Genin, there are those who are beginners, there are those who are slightly better, and there are also those who are more experienced.
