Most abilities in the ninja world are based on energy like chakra.

The Nine Tails are the source of chakra, that is, the ten-tailed sacred tree split out, and the nine-tailed chakra share is almost half of the ten-tailed chakra.

With a research material like the Nine-tailed Demon Fox, Li Yan quickly parsed out most of the secrets of chakra.

"Boss, what are you going to do?"

Just now he was freed from endless experiments and was about to rest, Jiuwei was woken up by Li Yan again.

"I just had to be so listless after only one night?"

Li Yan stroked the nine-tailed hair, as if the nine-tailed demon fox, more than ten meters tall in front of him, was a pet.

In a sense, Jiuwei is indeed just a pet to him.

Li Yan said: "Next, I'm going to make a gadget in the ninja world. In order to make this gadget more convenient, I need your chakra support."

"Chakra supports it? You obviously have more chakras in your body than me..." Jiuwei couldn't help but complain.

But it didn't dare to refuse.

Follow Li Yan honestly to the sea.

After overnight construction of intelligent light and brain, the crystal city has grown to a size of hundreds of kilometers long and wide, with an area of ​​tens of thousands of square kilometers, comparable to a metropolis.

But there are only two lives in the metropolis at this time.

Soon, the two of them came to a huge tower.

This crystal city is built at a depth of hundreds of meters below the sea.

This crystal tower not only penetrates the water surface, but also has a height of thousands of meters higher than sea level.

Li Yan said to the nine-tailed demon fox: "Enter chakra into it."

Jiu Tai did not understand the meaning, so he only placed his hand on a crystal ball as Li Yan ordered, and kept entering chakra into it.

Its chakra is said to be almost endless.

But at this moment, it felt a little difficult again. This night, it had felt it had no idea how many times...

Finally, it was not until the chakra inside the body was about to be hollowed out that it could barely meet the needs of the crystal ball.

"Don't worry, when designing, I took your chakra volume into consideration and would not overdraw you."

Li Yan smiled amiable, like a boss who cared about his employees very much.

Jiuwei was panting and gritted her teeth at the smiling guy. A bunch of swear words flowed through her heart, almost unable to help blurting out.

At this moment, Jiuwei suddenly felt the scenery in front of him change.

Then the swear words in my heart echoed in my ears like thunder.

"The bastard who should go to hell, a hypocritical little white face... When I am stronger than you, I will definitely tear you to pieces..."

As soon as he finished speaking, Jiuwei suddenly became panicked.

It was just thinking about it, why did it really say it?

"You're so angry with me for only one day? Alas, I rescued you from Konoha's robber's nest." Li Yan said with a little regret.

The smile on his face became even more amiable: "Continue to maintain this attitude, so that I will not have any psychological burden when I squeeze you..."

Jiuwei shivered all over his body. It wanted to explain something, but it couldn't open its mouth.

Finally, he put his head in his tail and hid beside him and shivered.

Suddenly, after hearing a snap of his fingers, Jiu Tai felt countless auras suddenly descending beside him, and it couldn't help but seeped an eye out of the gap in its tail.

I saw Li Yan said with a smile: "Everyone, welcome to my world."

At this time, Jiuwei realized that he and Li Yan were standing on the same platform.

Below the platform, rows of seats are distributed in a stepped shape. After preliminary estimates of Jiuwei, it was found that the number of seats was nearly one million, and now a small half of these seats have been occupied.

The people on the seat are men and women, old and young.

At first glance, there are at least 200,000 to 300,000.

"Who are you?"

“Where is this?”

"Am I hit the illusion?"

Hundreds of thousands of people were bustling with each other, facing the changes in the scenery in front of them, they asked questions in their hearts.

Finally, it gathered into several problems that had the most common problems.

Li Yan replied with a smile: "It doesn't matter who I am. You can call me an administrator; and this is the illusion space I created through a large illusion. Now it is the first time that all the people with chakra in the entire ninja world will come here."

Hearing this, the bottom suddenly exploded.

Many people don't believe this at all.

They do not think that there are such powerful people in this world, nor can there be such powerful ninjutsu.

"What exactly do you want to do?" A bursting voice overwhelmed many people.

"Thunder shadow?"

After hearing this sound, many people looked in that direction.

Suddenly, the square became even more chaotic.

"I didn't expect that even the Five Shadows came? It's Naruto sitting near the Thunderstorm."

"The first row is full of big figures from the major ninja villages!"

"Who is the cripple sitting in front of Wuying? He actually sat in the first place!"

"My purpose is very simple, just to benefit the ninja world." Li Yan said with a smile: "First of all, I will tell you how to enter the illusion space. It is very simple. You only need three handprints and condense the chakra in your eyebrows at the same time."

After saying that, detailed sealing techniques were projected on the high platform, and the trajectory of chakra in the meridians was demonstrated.

Li Yan reminded again: "It should be noted that entering my illusion space will consume a lot of chakra, so ninjas with few chakras must have self-control. The consequences of exhausting chakra are not required for me to know much."

Hearing this, many ninjas said angrily: "Entering the illusion? Who wants to be foolishly controlled by illusion? Is such a person worthy of being a ninja?"

"You bastard? Let us out quickly!

Li Yan smiled when he heard the noisy words.

These ninjas will eventually understand what the law of true fragrance is!

He continued: "I have built a library with a pretty good collection of books in this illusion. I hope to spread knowledge widely in the ninja world. Of course, I also hope to make more books in the library."

"The library has five floors, and I distributed all the books in the five floors according to the functions, information depth, learning difficulty, etc.."

"Books on the first floor of the library can be read for free."

"If you want to enter the second floor of the library, you need to provide a recognized knowledge every time you enter, which can be ninjutsu, technical knowledge, or an understanding of a certain substance. In the words that most ninjas can understand, provide a recognized ninjutsu or above that can be recognized, and you can enter.

"If it is recognized fifty times, you can obtain permanent access rights on the second floor of the library."

"Hmph, is another guy who wants to deceive ninjutsu by using the three-legged cat methods?" The Fourth Generation Lei Ying sneered.

Most of the people present had similar ideas.

Li Yan did not care about these noises and continued: "Similarly, if you want to enter the third floor library, you need to provide more profound knowledge. If you are recognized for forty times, you can have the permanent entry rights of the third floor."

“And so on.”

After saying that, Li Yan snapped his fingers gently, and the scene in front of hundreds of thousands of people changed again.

They appeared in a huge library reading room.

Countless books float in the air in different categories. If you want that book, you just need to think about it and you will copy one in your hand.

"There are so many yin qinji...?" The fourth generation of Naruto Naruto looked at one of the books with a complicated expression.

A feeling of meeting a confidant came from my heart.

But he couldn't believe that these unimian stings were real. In his mind, the books on the bookshelf might just be a name.

He couldn't help but click on one of them.

"Feng Chong Finger, Burning Fist, Flame Knife... Hunyuan Palm? What a shit Hunyuan Palm? This principle, this power, this...Isn't this a spirewan?"

He held the books in his hand tightly.

The Rasuchimaru was developed in three years, and he didn't mind letting the ninjas in Konoha Village learn.

According to the administrator of this library, everyone can watch the books on the first floor for free.

Watch for free!

As long as you have chakra and you can enter this library, you can watch it for free!

In other words, all ninjas in the entire ninja world can learn the spirewan he worked hard to create...

Even though the fourth generation of Naruto was extremely graceful, he couldn't help but swear words at this time.

Isn’t this bullying honest people?
