When Kakashi Hatake was away, many things had to be handled by Mizuki.

The Security Department, which faces most of the villagers of Konoha, is the busiest department in the entire village.

For an ordinary village, the law and order maintenance department would not have much trouble, but Konoha was different.

The strongest ninja village in the ninja world had a population of over 100,000 during its peak period of the year. There were few cities in the ninja world that were larger than this.

Although Konoha is named after a village, it has actually long exceeded the scope of an ordinary town.

During the Warring States Period, it was absolutely impossible to maintain such a large-scale human settlement.

However, with the formation of the one country, one village system and the dynamic balance of the confrontation between the five major ninja villages, the ninja world finally broke the bloody feuds based on families for nearly a thousand years, and replaced it with a secular country supported by the military force of the ninja village.

The establishment of order is the foundation of order from chaos. The ninja world is no longer dominated by powerful ninja families. Ordinary people also have the basic right to survive and leave their mark in the world.

Sporadic wars have never stopped, but the overall situation is peaceful.

In many places in the ninja world, the years without war are much longer than the years of war, so much so that a peaceful country like the Land of Hot Springs, which has almost forgotten the war, was born.

Order is the cornerstone, allowing civilians without chakra power to be revitalized. The biggest change to the ninja world is the development of humanities and natural sciences.

After nearly a hundred years of accumulation, the current level of civilization in the ninja world is on the eve of the second industrial revolution.

Due to the existence of chakra, the first industrial revolution - the steam age did not have much impact on the ninja world. The simple mechanical industry and crude gunpowder firearms did not shake the foundation of the ninja.

But it is not certain what will happen next. Fortunately, ninjas are not pedantic and have a good ability to accept new things. They have no interest in hunting down witches and burning sages to death, nor do they eliminate various heresies. Instead, they continue to absorb the achievements of the development of the ninja world and continuously combine secular power with chakra, resulting in the current somewhat bizarre results.

In general, the ninja world is developing at an increasingly faster speed. Konoha Village is the guiding light of the ninja world. It basically does not miss out on any new things. Electric lighting was the first to be popularized, and there are more and more daily household appliances. Movies, a daily entertainment, have long become a part of the villagers' lives.

As the deputy director of the Security Department, Mizuki can see even more.

Konoha Village is expanding slowly but steadily. The buildings in the village are getting taller, the old wooden houses are gradually decreasing, and various construction techniques are emerging one after another.

From Mizuki's point of view, Konoha Village is almost entering the era of electrification that is unique to the ninja world. Of course, it will take a long time for it to be popularized throughout the ninja world, but as long as nothing unexpected happens, this trend will not change.

Ninjas did not become a hindrance to development, but instead accelerated the process.

High-ranking officials such as Orochimaru, Mizuki and even Danzo possess the highest academic achievements in the ninja world.

Chakra is a convenient tool that allows powerful, imaginative and intelligent ninjas to easily explore some of the superficial rules of the ninja world.

When these things spread downward and intersect with the existing achievements of the ninja world, a good fusion will be achieved between them.

…

“I’m so tired!”

Maintaining public security in a small place with a population of more than 100,000 is so difficult. I don’t know how the previous leaders survived.

Of course, there weren't so many things happening decades ago. Looking at the vibrant scene outside the window and the endless stream of people, Shuimu felt a headache.

"I really am not cut out for this. If Kakashi doesn't come back, I will have to shoulder the responsibility."

Although Shuimu doesn't have to take care of trivial matters at home, he still has to review many things and then give instructions. For example, now, subordinates' requests for leave, job changes, or temporary assignments all need Shuimu's stamp.

"Jounin assessment mission, Hyuga Neji?"

Mizuki smiled as he held up a ninja level chart.

"It's about time."

Uchiha Sasuke was promoted to Jonin early on, so it is not surprising that Hyuga Neji, who was originally not much behind him, was promoted at this time.

After Mizuki quickly finished processing the documents that were half a person's height on the table, he stood up and stretched.

"Shiho, these have been processed, send them out quickly!"

After the Chunin Exam, Nara Shikamaru was transferred from the Security Department. Because of his efficient work, he was valued by Tsunade and used as a secretary and errand boy.

A newcomer was added to the Security Department's chores. A female ninja wearing thick-rimmed glasses, Shiho, replaced Shikamaru's original position.

Although she was defeated in the Chunin Exam a year ago when she teamed up with Yamanaka Ino and Akimichi Choji, her intellectual talents are still highly valued.

Shiho, who was promoted to Chunin, has not been an intern in the Security Department for long, but she has done a good job. However...

Shiho is an admirer of Nara Shikamaru. She usually doesn't pay attention to her appearance and is always timid and unpredictable in front of Shikamaru. She probably can't compete with the decisive Temari.

"Go out for a walk when you have time. It's not good to stay indoors all the time. Go talk to Ino, Sakura, and Karin more!"

Shiho was stunned, not understanding what Mizuki wanted to say, but nodded anyway.

Seeing that the female ninja who was only one step away from the Drymono Onna didn't understand, Mizuki shook his head and walked out of the office. At the corner where no one was paying attention, he disappeared in a flash.

…

The Kingdom of Waves has benefited from the improved relations with the Kingdom of Fire and the Kingdom of Water since the completion of the bridge built by Dazna. The small country located on a major transportation route has become a must-go route for business and travel.

Unlike the overall prosperity of Konoha, the Land of Waves is filled with the atmosphere of a typical commercial city. The formerly poor and miserable people have begun to benefit from this change, and the country is becoming increasingly prosperous.

At a busy street corner, Shuimu stopped in front of a large two-story building that had been converted into a warehouse.

The weather was getting colder, but Yukimura was busy, sweating profusely, and Yuhuo was assisting him.

This is a simple shop, and its main business is to rent the space to traveling merchants.

As for making money, it's actually that simple. The key is that this property is becoming more and more valuable.

Mizuki bought it originally just to provide Yukimura with a place to stay.

Later, in order to find something for Yukimura and Yuihuo to do, they bought some businesses here, gave them a small salary, and let them live here happily...
