Konoha's dog is happy

In Saitama's previous life, Naruto officially published many books similar to the Book of Rin.

Although Saitama has not read these books, he has heard from his cousin and has a certain understanding of them.

And the five formula collections he bought - Lin, Bing, Dou, Zhe, and Zhen - were only a small part of them.

There are four more books in the same series as these five.

There are nine books in total for Lin, Bing, Du, Zhe, Zhe, Zhen, array, in front.

In addition, there are also some personal biographical books.

According to his cousin, among the large number of officially published peripheral books.

In fact, what is really valuable for collection is the five collections of formulas for setting up combat formations in the dream space.

Therefore, these five books are generally sold in sets.

These five books record the characters, ninjutsu and other related settings that appear in each stage of the Naruto plot.

For Saitama who is really in the world of Naruto, these five books are also the most important.

Opening the book of Lin, Saitama spent a long time and read the entire book twice in detail.

After that, he read the jutsu chapter recording the ninjutsu twice again.

The previous Chapter of Ninja records the various characters who appeared after the plot officially started.

Many of these characters are not even born yet.

So at this stage, this part of the content is of little use to Saitama.

But the Jutsu Chapter is different. This part clearly records all the ninjutsu that appeared in the early plot after the official start of the Naruto plot.

You know, there are as many as 84 ninjutsu recorded here.

Importantly, there are illustrations of analysis and users.

After having a general understanding of the entire Rin no Book, Saitama turned to the Jutsu Chapter again.

He planned to learn the relevant ninjutsu based on the analysis in the book.

Of course, he couldn't just learn those profound and high-level ninjutsu as soon as he came up.

So he was still prepared to start with the simplest three-body technique.

Turning to the page that recorded the transformation technique, Saitama read the analysis of the transformation technique again.

Unexpectedly, as soon as he had the idea of ​​learning this technique, the scene around him changed.

It was still the same training ground where Naruto and the others competed for the bell.

But this time, there was a little difference.

It was precisely because of this little difference that Saitama was surprised again.

The difference this time is that there is one more person, Umino Iruka.

Saitama was surprised and looked at Iruka carefully.

He instantly understood that this was not the real Iruka.

Because this Iruka who appears in the dream space is the adult Iruka.

That is, after the plot officially begins, the ninja school teacher Iruka.

Obviously, he will look like this about 13 years later.

And now in the real world, he is just a child.

In the end, Saitama easily deduced that this Iruka should be just a fake Iruka created in the dream space.

Then in the dream space, why do you want to create a fake Iruka here?

Saitama guessed that it had something to do with the transformation technique he wanted to learn.

Because the illustration of the character in the book explaining the transformation technique is Umino Iruka during his time as a ninja school teacher.

After thinking about all this, Saitama tried to say hello to this fake Iruka to see if he could get a response.

Unexpectedly, as he was about to walk over, the fake Iruka immediately transformed into Kushina's appearance.

嚯

This time, he was so frightened that he jumped back.

"Damn, what the hell, I'm scared to death."

After jumping away, Saitama patted his chest and said as if he was surviving the disaster.

After calming down, Saitama looked at the other person again. Unexpectedly, Iruka, who had turned into Kushina, immediately turned into Minato.

Now Saitama completely understood that the other party was teaching him the transformation technique.

"Hey, can you speak?"

Saitama didn't dare to get too close, so he stood there and shouted loudly.

The fake Iruka didn't react at all, and he immediately transformed into Kushina's form.

After testing it a few times, Saitama understood.

This fake Iruka couldn't do anything except teach him the transformation technique.

It's just a transformation machine, very unintelligent.

After one night

Dong dong dong

"Saitama-chan, are you awake?"

After Kushina got up, she was going to take Saitama to eat ramen. When she found that he hadn't gotten up yet, she started knocking on the door.

"Get up"

Saitama, who had just woken up, was still in a state of excitement.

Arriving at the Ichiraku Ramen Shop again, Saitama saw his hand-beaten daughter Iris.

A little girl about his age, small and very cute.

Saitama, who was eating ramen, started his brain teaser again.

Those five books are indeed the greatest treasures in the entire dream space.

He didn't expect that he could easily learn all three body techniques in one night.

When learning the Standing Technique, the adult Kakashi in the illustration was also simulated.

It's just that he's not proficient enough in these three techniques.

Although Saitama gained a lot this night, he still didn't understand how to open the remaining four books.

Saitama can only make preliminary guesses about the reason for opening the Book of Rin.

First of all, we must start with the emergence of dream space.

It shouldn't happen immediately as soon as you sleep.

Otherwise, why didn't he show up when he and Minato spent the night in the wild on the way to Konoha?

Instead, he had to wait until he was sleeping at Minato's house to enter the dream space.

Obviously it wasn't because he was more comfortable sleeping at Minato's house that he was allowed to enter the dream space.

So what's the difference between these two nights?

The only thing Saitama can think of, and thinks is most likely, is chakra.

That night in the jungle, Saitama had not yet extracted chakra from his body.

After arriving at Minato's house, Kushina immediately began to teach him how to extract chakra.

He also successfully extracted chakra before going to bed.

Then consider the now known role of the dream space in assisting cultivation.

Saitama can almost conclude that this dream space appeared because he possessed chakra.

For a very simple reason, the dream space assists ninjas in their training.

If there is no chakra, then the existence of this space is meaningless.

Therefore, this chakra should be a prerequisite for the opening of the dream space.

Otherwise, in this world of Naruto, it would be impossible for Saitama to use this dream space to cultivate internal strength, fighting spirit, martial arts, etc. without chakra, right?

If the dream space has a function similar to the mall system, which can directly obtain power, then it is possible.

But Saitama has been researching for a long time and has not found any data panel, system wizard, mall, lottery and other functions.

Saitama was also a top student in his previous life. From this limited information, he deduced that there must be prerequisites for the opening of those five books.

Through the analysis of the prerequisites for the opening of the dream space, Saitama felt that the opening of the Book of Rin was probably related to his learning of the Clone Technique.

The first time he entered the dream space, he only practiced extracting chakra and did not open the book.

The second time I entered the dream space, the book was still not opened.

During this period, he practiced the art of cloning.

But then he had no blue left and began to recover chakra, and he was woken up not long after.

It was the third time I entered the dream space. As soon as I entered, I had not started to do anything.

The word on the cover of Lin Zhi's book has changed from "sealed" to "liberated".

That meant that the words on the cover of Lin Zhi's book should have changed before he came in for the third time.

And when he first came in for the second time, it was clearly sealed.

Therefore, Saitama guessed that it was what he did inside after he came in for the second time that caused the book of Lin to change from "sealed" to "unblocked".

What have you done

only one.

That is, he learned the art of cloning in this dream space.

After learning how to clone, he didn't read the five books anymore. Instead, he directly chose to sit down and restore his chakra, and then he was quickly woken up again.

The second time he entered the dream space, he only read the five books when he first entered.

From then until he left, he didn't look at the five books again.

So at that time, the Book of Lin should have been opened.

Since it is confirmed that it is related to learning the clone technique, then why did there not be any changes in the other four books after he learned the transformation technique and the body double technique?

It should be that the prerequisites for opening have changed.

Saitama guessed that the prerequisites for opening each book should be different.

After doing a series of reasoning, Saitama finally understood the prerequisites for opening the Book of Rin.

It's not that I learned the clone technique, but that I learned the first ninjutsu.

Although Saitama has done this series of analysis, his thinking seems to be basically okay.

But he still had no idea about the prerequisites for opening the other four books.

After all, only two sets of data are not enough to complete the analysis.

"Saitama-chan, are you full?"

After finishing the ramen, Kushina wiped her mouth with a tissue and touched Saitama's bald head and asked.

"Well, I'm full."

In order to get away from Kushina's hand, Saitama quickly jumped off the bench after finishing speaking.

"Okay, then I will take you to see the largest and most distinctive scenery in our Konoha Village."

Kushina took Saitama's little hand and walked directly out.

“The largest and most distinctive scenery”

"What is that?"

Although Saitama had some guesses in his mind, he was still a little unsure.
