After learning about the past of the turtle master, Li Kuan took the opportunity to learn about the secrets of Asura from it.

Well, Li Kuan understands the world, but what he understands is focused on the prince and Erzhuzi as the protagonists, and other supporting roles and the like, only understand animation, and information appears in comics.

And the supporting characters in supporting roles like Asura, characters who haven't even appeared a few times in anime and manga, then there's basically nothing to understand!

However, he wants to conquer the Hokage world, and the Otsuki family is an unavoidable knot, so he learned about the secrets of Asura from the turtle master to see if he can learn about the Otsuki family from the inside!

But the result...

Not to mention the big barrel wood, even if it's an asura thing, it can't say it.

However, it's not that the turtle master doesn't say it, but it doesn't know either.

Back then, although he often accompanied Asura, before he became a psychic beast, and when he just became a psychic beast, he still had no IQ, let alone memory, and he couldn't remember many things at all.

Moreover, it has been countless years since I was separated from Asura, and apart from the happy time with Asura that I still remember, other memories have long been blurred!

And because of this, it doesn't know.

In this regard, Li Kuan was slightly disappointed.

But he soon put the matter behind him.

Although this matter was very important, for now, it was not important enough to know, and he had two more important things he wanted to know from the Turtle Master about the direction of --- Chakra Extraction Technique and the land.

Among them, the reason why you want the direction of land is simple.

Only by finding the land, finding the Konoha he is most familiar with, and entering the most familiar plot, can he obtain the greatest benefits in this plane!

And the chakra extraction...

Although it's called Chakra Extraction, if you think about it carefully, isn't this just a cultivation technique?

Li Kuan had been thinking about cultivating the exercises before, but now that he had it, he naturally wanted to get it.

So, Li Kuan asked the turtle master again.

And this time!

Master Turtle did not disappoint him.

Land and Chakra Extraction It speaks for itself.

Perhaps because of the asuras, every year after reaching the day when it was separated from the asuras, it would go to the edge of the land and the sea to have a look and reminisce about the asuras, and it has not stopped.

So it knows where the land is.

The chakra extraction technique is similar, because it was taught by the asuras, so it is still practiced until now.

Although it has gradually become a little dissatisfied with its food due to its growing size over the years, it has fallen into a deep sleep all year round in order to survive, but as soon as it is not asleep, it begins to refine chakra.

---

"Wow~"

On the endless sea, a huge island is moving forward quickly across the water.

And in the middle of the island, in a cave, a young man was looking down, frowning as if thinking about something.

That's right!

This is exactly Li Kuan and the turtle master!

"It's weird, I followed the steps, why can't the chakra be extracted?" Li Kuan frowned and muttered.

At this time, he was thinking about how to extract the chakra!

After getting the chakra extraction from the turtle master, Li Kuan immediately tried to extract the chakra, but the result... No matter how much he tried, he couldn't extract it in the end.

He was sure that he did exactly the same steps, or sequences, or anything else.

"Could it be that there are other prerequisites for chakra extraction?" Li Kuan muttered, a flash of inspiration flashed in his mind, and he suddenly had an idea.

Maybe...

Really need something else!?

Li Kuan thought of a detail in the original book.

The Fourth Ninja World War, the number of people who participated in the battle!

Li Kuan remembered that at that time, a total of 80,000 people came out of the five major powers plus the six strongest countries in the ninja world of the Iron Country.

Among these 80,000 people, the number of people from the specific five major countries and the land of iron is unknown.

However, Li Kuan guessed that the Land of Iron should have produced thousands of samurai!

After all, the five major countries and the iron country have only dispatched 80,000 people.

If the Iron Country dispatched tens of thousands of samurai, the other five countries averaged out only tens of thousands of ninja in each ninja village, which is a bit unreasonable.

According to this calculation, the Iron Country has a strength that can be compared with the five countries.

But if only a few hundred samurai were dispatched, it would be a bit unreasonable.

The Five Shadows Conference can be held in the Iron Country, although there is a reason why the Iron Country has always been neutral, but it also indirectly shows that the five major powers are more recognized by the strength of the Iron Country.

If the Iron Country itself is too weak, even if it is a neutral attitude, the five great powers will not be relieved to hold the Five Shadows Conference here!

What if a village has evil thoughts in his heart and threatens the Iron Country to cooperate and do something at the Five Shadows Conference?

Therefore, the Iron Country must have a certain strength, and it will not be threatened by a certain village in the five major countries, so that it can be recognized by the five countries and hold the Five Shadows Conference here.

Based on this, the Iron Nation dispatching a few thousand samurai is a reasonable number.

Excluding the samurai of the Iron Country, that is to say, the ninjas of the Ninja World Alliance are about 75,000, and if you calculate with these 75,000 ninjas, you can probably conclude that the total number of ninjas in the Naruto World is more than 100,000, not more than 200,000.

Well, at that time, the five major countries could be said to have poured out, even if there were still a little ninjas left to prevent the ninja village from being attacked by a sneak attack, but even if they were added, the total number of ninjas in the five major countries would not exceed 100,000.

In addition to the five major countries, although other countries also have large and small ninja villages, Li Kuan estimates that the villages with the most ninjas in these ninja villages are only one or two thousand ninjas.

Why?

Because the five great powers can't tolerate it!

If there are four or five thousand, five or six thousand ninjas in these ninja villages, they can influence the war between the five great powers!

After all, the coalition forces are only tens of thousands of ninjas.

On average, there are only 10,000 or 20,000 ninja villages in the five major countries... Maybe there are a little more Konoha leaves, but it's definitely not much.

In this case, if there is a village with a number of four or five thousand, five or six thousand, it will definitely suffer from the hostility of the five major powers, and even the cake of exterminating the --- ninja world is so big, if there is one more person, the five major countries will eat less.

Therefore, the maximum number of these villages is one or two thousand, and the minimum is a few dozen.

And under this number, it can be known that the ninjas in the small ninja villages other than the five major countries, plus the scattered wandering ninjas, are estimated to be only tens of thousands.

Well, there are many ninja villages in the original book, but there are only a few in total, taking the area of the ninja world as a reference, plus the non-appearing, it is estimated that there are only one or twenty ninja villages!

Because of this, Li Kuan came up with a total of more than 100,000 ninjas in the ninja world, and no more than 200,000 ninjas.

And with a total of more than 100,000 ninjas, what is the total population of the Hokage World?

Li Kuan didn't know.

The original book doesn't talk about this.

But he estimates that there should be at least tens of millions, if not more.

In ancient history, a soldier who was out of work needed hundreds of people to support him, or even more, otherwise the country would not be able to hold on.

Based on this, coupled with the fact that in addition to some black technology in the Hokage World, the others are similar to those in ancient times, and it can be concluded that the Hokage World has at least tens of millions, or even hundreds of millions, of people.

Well, there are more than 100,000 ninjas in the ninja world, and if there are no tens of millions or even hundreds of millions of people, they will definitely not be able to support these more than 100,000 ninjas who basically do not participate in production.

But here's the problem.

Among these tens of millions, or even hundreds of millions, why are there only more than 100,000 ninjas?

You must know that there are more than 100,000 ninjas in the Hokage world, and these more than 100,000 people not only have many wandering ninjas, but also many people have some civilian relatives or friends, so the knowledge about ninjas must not be blocked, and some of them are spread.

It shouldn't be too difficult for civilians to get those foundations.

But that's it, ninjas still only have so little, which is a bit unreasonable!

With the power of a ninja, no civilian would refuse to become a ninja if given the chance!

Otherwise, How did a wandering ninja come about?

Therefore, Li Kuan felt that there should be some special conditions that restrict ordinary people from learning ninjutsu.

And again!

The entire Hokage world, from the Warring States to the Fourth Ninja World War, has basically never stopped fighting.

And this is a direct result of this, when the situation is most critical, even those children who are six or seven years old have to go into battle.

But here's the problem!

Why did Ninja Village let these children go to school, instead of simply cultivating adults?

Adults are a little more mature in their thinking, and in relative circumstances, adults become ninjas, even if they are just cannon fodder ninjas, it is obviously more suitable than children!

As you can see from this, there are conditions for becoming a ninja.

It's like cultivating immortals, what are the roots, spiritual roots, qualifications and the like.

It is only with these things that we can explain why we don't just train adults to be cannon fodder, but let children participate in this cruel and bloody ninja game.

As for what the conditions are...

Li Kuan hasn't thought of it yet.

No way!

There are so few things that are known so far, no matter how much he is, there is no way to speculate!

However, based on the above speculation, he has a relatively certain guess that he can't refine chakra!

The main reason why he can't extract chakra is probably because he is not from this world.

If you are not a person from this world, it is naturally impossible to meet the conditions for becoming a ninja, so the chakra extraction technique is naturally useless!

"Isn't it exactly, when you get to land, get a few ninjas over for testing, and then experiment a few times, you should be able to know!" Li Kuan thought secretly in his heart.

That's when it happened!

As far as he could see, he suddenly saw a long stretch of coastline appear in the sky.

It's obvious!

Land has arrived!
