Start with a Zanpakuto and build the strongest Mist Village.

"This library allows you to borrow ninjutsu?!"

Zabuza stared at Ao in astonishment, and his companions also wore expressions of disbelief.

A smile appeared on Qing's face. He nodded to the guard in charge and led the young men into the library.

"It's just as you see it."

"The entire Mist Hidden Duel Tower is divided into eight floors. The top floor, where we are currently, is the open-air Mist Hidden Library."

"Here, you can borrow materials including ninjutsu, secret techniques, secrets, information about the ninja world, etc. from the ANBU administrators. As long as your identity and the information of the borrowed books are registered, you can even take them out of the library."

Zabuza was somewhat incredulous and casually picked up a blue scroll.

The scroll was opened, and it turned out to be a detailed analysis of 'Water Release: Waves'!

He picked up another one, and it turned out to be another Water Release ninjutsu!

Zabuza looked up in disbelief. The bookshelf in front of him was labeled with the words "Water Release".

On another bookshelf nearby, there were also books labeled 'Fire Release', 'Wind Release', and so on.

As children of a ninja academy, they are naturally familiar with ninjutsu, but in fact, ninja academies do not teach much about escape techniques and ninjutsu; most of their instruction is in basic ninjutsu.

Such ninjutsu techniques, apart from those from powerful clans, are usually purchased by ordinary ninjas through large sums of money or mission contribution points, or exchanged with the village. Unlike now, they are simply placed here and made completely open for everyone to watch.

Moreover, these ninjutsu scrolls also contain instruction and commentary on the ninjutsu, and even instructions on how to better perform the techniques.

No wonder this place is packed. If it were them, they would be happy to stay here all day long!

Looking at the stunned students, Qing couldn't help but smile, remembering the same shocked expression on her face when she first came here.

"Of course, although all the ninjutsu in the library are open to the public, in order to prevent you from practicing high-level ninjutsu before you have mastered the low-level ninjutsu and laid a good foundation, the library is temporarily only open to the public for E, D and C level ninjutsu, and you can only borrow one book at a time."

"As for higher-level B, A, and S-rank ninjutsu, as well as some special secret techniques, they can only be viewed after an application is approved."

They even have A-rank and S-rank ninjutsu?!

Zabuza Momochi was utterly shocked. Even some ninja clans didn't have many ninjutsu of this level.

Putting everything else aside, the Momochi clan only has a few A-rank ninjutsu, and as for S-rank ninjutsu, they don't have any at all.

You can actually borrow books here?!

Don't go too far!

Many students were so excited that they grabbed books and stuffed them into their pockets.

"Borrowing books isn't urgent for now. The main reason I brought you here today is to introduce you to the entire Mist Hidden Duel Tower, because our graduation exam this year is related to this newly built Duel Tower."

"Next is the second floor."

With a heavy heart, Qing left the Hidden Mist Library, feeling as if she were in paradise, and began her journey to the second floor.

Zabuza and the other students could not hide their excitement and quickly followed Ao's steps.

If there are so many surprises on the first floor, what will the next floor be like?

The first and second floors were not far apart. After descending two flights of stairs, a dark door appeared in front of them.

Instead of leading the students directly inside, Qing took out a special crystal pendant from his pocket and distributed it to each student.

"Before entering the second floor, please put on this spirit crystal pendant. Of course, this is a temporary one, and you should take it back after you leave."

Qing explained that after confirming that all the students were wearing their spirit crystal pendants, he pushed open the dark door and stepped inside.

Behind them, Zabuza and the other students looked at the dark gate, feeling a sense of adventure, and followed Ao with curiosity in their eyes.

The light in front of them suddenly dimmed, and then a layer of faint blue light appeared before everyone's eyes.

But the moment this glimmer of light appeared, all the students present, including Zabuza, changed their expressions drastically. Many students even squatted down on the ground, their bodies trembling!

Seeing the students like this, Qing did not stop them or do anything.

The area they were in was the second layer, the area with the least pressure, where the protection threshold of the spirit crystal pendant had not even been triggered.

This pressure won't affect them much; even if they stay here for a long time, they'll just sweat more and experience muscle soreness.

"This is……"

Zabuza frowned, feeling as if he were moving in water, with a resistance permeating his entire body.

"This is the second floor of the Hidden Mist Duel Tower, and also the first floor of the training level."

Qing kindly pulled up several students who were exhausted from playing with glue all day and explained, "This so-called training level was created by the Mizukage and the higher-ups using special equipment. It's a place specifically for the Kirigakure ninja to train."

"The entire cultivation process consists of six levels, ranging from S to E, with each level having a different pressure intensity."

"The second floor we are currently on is the least stressful floor, and it is also one of the contents of our graduation assessment. So, some students who feel their legs trembling and cold sweating just by staying on the first floor should pay attention. Please get some rest early tonight, put aside some inappropriate reading materials, and control your hands."

Qing didn't name names, which made many students' faces stiffen. They gritted their teeth, their faces flushed with pressure, and forced themselves to maintain a proper posture to show their innocence!

Seeing their appearance, Qing couldn't help but let out a soft snort.

"The pressure here is not simple."

"The reason this place is named the Cultivation Layer is because training under this pressure will not only improve your physical constitution, but also your taijutsu, swordsmanship, body flickering techniques, and chakra control. Even refining chakra here will make it more condensed!"

"Moreover, this pressure will not cause any harm to the natural growth of the body, so you young lads are in luck. As long as you stay here for a long time, your future achievements will definitely not be inferior to ours, and you may even become strong like the Mizukage!"

Upon hearing this, the little ones who had been struggling under pressure to prove their innocence suddenly had their eyes light up.

Many people have even decided to bring their bedding, toiletries, and other necessities from home and stay permanently!

Qing was not surprised by the young men's sudden enthusiasm.

Whether in the Blood Mist Era or in this new era, the Hidden Mist's reverence for the strong has never changed, especially now that the Mizukage is just a fifteen-year-old boy.

It can be said that Ye is now the idol of the entire Hidden Mist Village, especially the boys in the Hidden Mist Ninja Academy.

Because of the small age gap, Ye became a mobile oxygen pump for these kids. Every teacher asked them what their dreams were, and nine and a half out of ten dreamed of becoming like the Fourth Mizukage!

"Alright, alright, there's more to come, let's collect them all."

Qing clapped his hands and led the sweating students out of the second floor. As soon as they came out, all the little ones breathed a sigh of relief. Their clothes were soaked with sweat, as if they had been pulled out of the water.

Qing didn't lead these kids around floor by floor, but instead took the students straight to the eighth floor.

"Next is the most important floor of the entire Mist Hidden Duel Tower, which is also the origin of the tower's name."

"Duel Zone!"

The students were already bursting with excitement.

In Zabuza's mind, numerous images appeared.

Arena!

Arena!

Duel Arena!

A life-or-death duel!

Various images flashed through his mind, and his inner anticipation reached its peak.

But when Ao, with a mysterious smile, led them closer to the duel floor, Zabuza and the others showed an expression of disbelief and astonishment.

What they saw was not the scene they had imagined at all; there was neither a passionate clash of ninjutsu nor a brutal physical confrontation.

There wasn't even a trace of anyone fighting.

A huge blue crystal ball hangs in mid-air.

Below the crystal ball, rows of special instruments filled the entire duel level, some in pairs, others in six piled together.

Dozens of people dressed as Jonin or Chunin were sitting in front of the instruments, looking tense.

This isn't a duel floor at all; anyone who didn't know better would think it was an arcade!

"Don't underestimate these things. These are the 'battle devices' specially made by Lord Mizukage!"

With a solemn expression, Qing picked up a combat device and began to explain.

"Because of the risks of physical combat, the Mizukage created these special devices so that the Hidden Mist ninjas could experience the absolute struggle between life and death without paying the price of their lives."

"Using these instruments, your consciousness (soul) will enter a virtual space to engage in a duel."

"In the virtual space, you will not only synchronize your physical state, but also experience 100% holographic sensory perception. Even pain simulation is 100% real."

"You will not only feel all the pain you experience in battle, but also the chakra depletion that occurs every time you use a ninjutsu. Apart from death, everything you experience here is no different from reality!"

"what!!"

As if to confirm Ao's words, the moment his voice fell, a Kirigakure ninja wearing a Chunin vest let out a miserable scream, then suddenly opened his eyes, staring in shock at what was in front of him.

Beside him, another Chunin from Kirigakure slowly removed his combat device. Although he also looked somewhat nervous, he did manage to smile.

"I won!"

"Damn it, it was so close..."

The defeated Chunin let out a low growl of resentment, then walked out of the duel floor with a pained and dejected expression, heading towards the outside world.

"Of course, although you won't actually die in a simulated duel, the mental damage from death is still enormous."

"Normally, death in a duel requires a day and a night of rest to recover. If you try to force a duel when you are not in good mental condition, you may even be turned away by the 'Battle Device'."

"Therefore, when you duel in the future, it is still best to stop there."

Ao explained, and the kids nodded as if they understood, with Zabuza even more eager to try, but he was stopped by the Anbu management personnel standing nearby.

"You're not qualified, kid."

"what the hell!"

Zabuza looked indignant, while Ao smiled and said, "Sorry, I forgot to mention that the Duel Arena is currently only open to Chunin and above."

"Ah, no..."

"So if you want to experience it, then train yourself well in the cultivation level!"

The little kids immediately looked miserable and frustrated.

Ao and the ANBU ninja exchanged a glance and then burst into laughter.

"It seems that having you take care of these little guys was indeed a normal choice, Qing."

The sudden sound brought their laughter to an abrupt halt. Qing and the Mist Shadow Anbu members immediately changed their expressions, then solemnly bowed to the little brats.

The kids belatedly realized what was happening and quickly turned around, only to find Yoru, dressed in a blue and white divine robe and wearing a water-shadow hat, smiling at them.

"The Fourth, the Fourth Generation Lord!"

"Greetings, Fourth Generation Lord!"

Their faces betrayed their barely concealed excitement and respect. Qing bowed his head and said respectfully, "I didn't actually do anything. It's all because the students have a good foundation!"

"As the future hope of Kirigakure, their foundation must be excellent."

Mizuki Yoru smiled and waved, her gaze falling on Zabuza: "I remember you're from the Momochi family, right? Not bad."

"My name is Zabuza Momochi! Fourth Hokage! Thank you for the compliment, Fourth Hokage!"

Zabuza was stunned when he heard Yoru's praise, as if he couldn't believe his ears. Then, with a look of nervousness and excitement, he gave Yoru a deep bow, making Yoru's smile even brighter.

"Momochi Zabuza, huh? Not a bad name!"

"You don't need to be so polite. I'm just here to check on the tower's operation. After all, it's only been running for a short time. You can all go about your business and don't need to worry about me."

"Yes, Fourth Hokage!"

Yoru patted Zabuza on the shoulder, and then, amidst the admiring and respectful gazes of the crowd, walked deeper into the eighth floor until he disappeared from their sight.

It has to be said that being the Mizukage is quite exhilarating. Putting aside the power, the feeling of being revered by countless people is enough to make one feel intoxicated.

No wonder the Third Hokage, Hiruzen Sarutobi, didn't go after the Fifth Hokage after Minato Namikaze, but instead came out and took power himself.

With a broad smile, Ye inspected the eighth floor before disappearing through the gate.

However, he did not leave, but instead went to the bottom floor of the Misty Duel Tower.

Yes, this Misty Duel Tower actually has a ninth floor in addition to the first eight floors.

However, there wasn't much on the ninth floor, only a few puppet-like figures and a huge instrument.

The instrument was covered with various sealing talismans, as if it were binding something.

During this period, in addition to the construction of Wave City, the construction of Rejuvenation Land also continued.
