Naruto: Starting by Teaching Tsunade Modernization

After Kakuzu finished his hot pot, he headed to the Seventh District.

Since he lived in Akihabara, he was most familiar with the Ninth District.

In his opinion, the Ninth District was the most modern, prosperous, and fun street in the whole of Konoha.

In his long life, Kakuzu had seen everything, but there were always new things in the Ninth District.

It gave him a great sense of excitement.

The Seventh District, on the other hand, offered a different view.

Due to the presence of two major banks,

there were quite a few people coming and going in this district.

But most of them were in a hurry and not here for fun.

Kakuzu looked around. It seemed that everyone on the street was a merchant.

Their outfits were somewhat similar.

Moreover, there were relatively few ninjas.

His eyes soon fell on two bank buildings shaped like money.

Actually, Kakuzu had heard of these banks before, but he only regarded them as underground money - lending houses.

Since he didn't borrow money, there was no need for him to come to an underground money - lending house.

But he never expected that there was such a strange business as time deposits.

He couldn't understand it at all. Wasn't this a loss - making business?

Kakuzu had only heard that borrowing money required high interest, but getting interest for depositing money?

He walked into the Konoha Savings Bank.

In the spacious hall, there was a transparent partition in the middle separating the employees and the customers.

Kakuzu found an empty window.

He knocked on the partition that looked like glass. It was very sturdy and seemed able to withstand an A - rank Ninjutsu.

As expected of a bank, the protective measures were excellent.

At the same time, he also noticed that there were monitoring devices everywhere in the bank.

Once someone committed a crime, the footage would be sent to the Konoha Police Force through the network cable.

Within a minute, a group of guys with [Sharingan] would arrive.

If the culprit escaped, the loss would be jointly borne by the Ninja Tools and Technology Research Department and the Konoha Police Force.

In the past month, quite a few people had tested this.

The only result was that the reputation of the Uchiha Clan had greatly improved.

After all, if the Uchiha retrieved what was stolen or stopped someone from hitting or killing you, you couldn't show a hostile attitude, could you?

"Sir, what kind of business do you want to handle?"

A young man in his thirties wasn't surprised to see Kakuzu's curiosity about the partition.

People often observed it out of curiosity.

He showed a formulaic and amiable smile on his face.

"We offer two types of services here: deposits and small - scale loans. For large - scale loans, please go to the investment bank next door. May I ask if you'd like to make a deposit or take out a loan?"

"Deposit."

"Okay. Deposits are divided into current deposits and time deposits. A current deposit allows you to deposit and withdraw at any time without restrictions, but the interest rate is average. A time deposit, however, can only be withdrawn after the specified term. Withdrawing before the term is not allowed, but the advantage is that the interest rate is very high."

"Tell me about the time deposit."

Kakuzu directly ignored the current deposit. The average interest rate couldn't attract him.

"Sure."

The young man's smile became even brighter.

For the bank, time deposits were undoubtedly more popular.

He immediately started to explain the interest rates for each time period to Kakuzu.

"Is there no option with a term longer than five years?"

"Huh?"

The young man didn't react at first.

It was the first time he had heard someone ask this question.

Because in the current ninja world, the average lifespan is only around thirty or forty years.

Five years is already quite a long time.

Moreover, many people are reluctant to save money for such a long period.

They are afraid of dying unexpectedly one day.

Besides, wars are frequent.

"Not for now," the young man thought for a moment and said. "If the customer has special requirements, we can make an application."

Kakuzu pondered slightly and didn't mention his own needs. Instead, he brought up a question he was very concerned about.

"How does your Konoha Savings Bank ensure the safety and reliability of deposits? And will you be able to repay the money after a few years?"

"Please rest assured on this point," the young man had answered this question countless times. "Do you know who established the Konoha Savings Bank and the investment bank?"

"Who?"

"The Hokage-sama."

Is Tsunade the person in charge?

Kakuzu frowned tightly. Since Tsunade was involved, Haruki must also be there.

If the bank was backed by these two people, there was no need to worry about it going bankrupt.

Although he didn't have affection for Haruki, this person was trustworthy.

Moreover, the bank involves so many people. Once something goes wrong, the Hokage would surely lose face, and the reputation of Konoha would also be affected.

Kakuzu was a bit tempted for a moment.

He had someone specifically take care of his money.

But it couldn't generate more money.

If he put the money in the Konoha Savings Bank, he could not only save the cost of hiring someone but also ensure its safety and earn interest.

He has the Earth Grudge Fear, so theoretically, he can live indefinitely.

The more Kakuzu thought about it, the more cost-effective it seemed. Isn't it awesome to earn so much money from Haruki for free?

Even if he knew about it, so what? You set the rules yourself. You can't go back on your word, right?

The only thing that bothered him was that if he deposited money, he would have an interaction with Haruki.

"I want to deposit five hundred million ryo," Kakuzu said slowly.

Even just the interest for five years, he can get nearly sixty million ryo from Haruki for free.

This was almost equivalent to two-thirds of Haruki's bounty.

Anyway, the money would just sit there at home or in the bank.

"What?!" The young man suddenly looked up, not believing his ears for a moment. "This... How much did you say, sir?"

"Five hundred million ryo."

"F...F...Five hundred million?" The young man stammered in shock. He had never heard of such a large sum of money in his life.

"Is that not allowed?"

"Of course it's allowed!" The young man suddenly stood up, with an excited and respectful expression on his face.

After some conversation, Kakuzu signed the contract. But his money was not in Konoha.

The next day, Kakuzu asked Haruki for a leave.

"You're not leaving?" Haruki had spent time with Tsunade the day before, and the bank's business wasn't reported to him, so he didn't know that Kakuzu planned to deposit most of his fortune in the bank and take advantage of him.

If he had known, he could only have told Kakuzu that although you live a long time, this new thing is too complicated and you can't handle it.

You made a profit, but I made even more.

"Well, Konoha is barely okay. I plan to stay here for a while," Kakuzu said indifferently.

Haruki couldn't help but smile.

The current situation in Konoha is that anyone who stays here for a long time and then goes to other places will find the difference is like that between heaven and hell.

He deeply felt this in his previous life. The contrast between Konoha (the city) and the countryside was quite striking.

However, with the influence of various factors, rural life has suddenly become popular.

"So you're going back this time to get your luggage?"

"Yeah."

"If you plan to stay in Konoha, how about changing your job content? The job is still teaching, but instead of teaching only Kakashi and Obito, you'll become a specially - appointed professor at the newly established Konoha Ninja University. What do you think?"

Haruki always thought it was a bit of a loss to have spent so much money but only taught two students.

"What kind of job?"

Kakuzu asked straightforwardly.

He didn't care about the job, only about how much money he could make.

"The salary remains the same or even higher. If you're willing to set up a research group to develop new Ninjutsu or Ninja tools, we'll allocate a generous research fund for you."

"Deal."

Kakuzu said without hesitation.

He knew a large number of Ninjutsu. After hearing about Haruki's so - called research group, he already had the intention to embezzle the funds.

Haruki watched him leave.

He wasn't worried.

All scientific research had to go through professional reviewers.

If Kakuzu could come up with an S - rank Ninjutsu, he'd be willing to give him the money.

Tsunade had gone to the Hokage Building in advance.

Haruki thought for a while and took a stroll around the school.

The Konoha Ninja University was an expansion of the original Ninja Academy.

With the reform of the education system, attaining the rank of Genin is no longer the graduation standard.

A normal ninja would go through primary school, secondary school, and university, and graduate after twelve years.

Considering the special situation of the ninja world, junior high school was cancelled.

Twelve years was already a very long time.

But in university, a part - work and part - study system was implemented.

To avoid wasting resources.

The ranks of Genin, Chunin, and Jonin have been changed to professional titles, which serve as extra points in exams.

"Teacher Haruki."

"Oh, it's Sasori."

Haruki saw Sasori of the Red Sand who greeted him.

After coming to Konoha, Sasori wasn't just assigned to be a scientific researcher.

Haruki made him an exchange student in Class A, Grade 2.

That was the class of Kakashi and Obito.

In the new year, they were no longer first - year students.

On the first day of school, Sasori, with the help of his Puppet, had a duel with the two geniuses, Kakashi and Obito.

Although he lost in the end, the beautiful and violent loli Shinku and the handsome young Sasori caused quite a sensation.

In just a few days, Sasori became very popular among the students.

Haruki had expected this.

Sasori and Shinku would be the focus wherever they went. It was normal for them to cause a stir.

He even had an idea to let the ninjas from Sunagakure come to study here.

"Are you getting used to it at school?"

Although Haruki held the position of a teacher, he hadn't taught classes for a long time and only heard about Sasori's deeds at school.

"Pretty good."

A smile appeared on Sasori's lips.

He met many nice friends here.

As the saying goes, geniuses appreciate geniuses.

In Sunagakure, there was no one among his peers who could match him. Naturally, he lost the desire to talk to them. But Konoha was different, where geniuses emerged in large numbers. Just Kakashi and Obito in his class could put pressure on him.

Moreover, Haruki had the Research Institute of the Xia Organization moved back, which interested him greatly. Without Haruki's persuasion, he would go to the Ninja tool research group whenever he was free.

Especially the Heavenly Fire. It caught Sasori's eye.

Not only that, he also saw various concept drawings given by Haruki. They were very cool and extremely powerful. But unfortunately, there were only external views.

"By the way, Teacher, Teacher Ichiro and I developed a new type of weapon yesterday."

"Oh? Let's go and have a look." Hearing this, Haruki immediately became interested. He wondered what kind of weapon Ichiro Muramasa had developed. He had made appearance drawings of all kinds of weapons he saw in movies in his previous life for them. Pistols, machine guns, airplanes, tanks, warships, Terminators, spaceships, Gundams, etc. Although Ichiro Muramasa thought most of them were too fanciful.

After the expansion of Konoha Ninja University, the Research Institute was no longer limited to underground laboratories. It openly occupied an academy.

"What's this?" Haruki widened his eyes, looking at this familiar and fierce killing weapon. With a gun body over two meters long, five large - caliber rotating barrels, and an overall black color, it showed a silent curvilinear beauty.

"Based on the appearance drawing you gave us back then, we improved it on the basis of the Heavenly Fire and used puppet technology to assemble this machine gun."

Oh! Seeing his reaction, Ichiro Muramasa couldn't help feeling a bit proud. He talked about the various data of this machine gun. Haruki could only nod.

"I didn't expect you really made a Gattling gun." He couldn't help sighing. Although the technology was completely different, the final effect was not bad. Even the drawback of its large weight could be solved by puppets. If the exoskeleton project is successful, he believes his new army will be invincible.

"The name Gattling is a bit strange." Ichiro Muramasa didn't dwell on it and continued, "Whether it's the Heavenly Fire or the Gattling, to achieve their maximum effect, they still rely on Chakra." It wasn't that the hot weapons from his previous life were ineffective, but the industry in the ninja world was not yet mature enough to reproduce them.

Haruki stroked his chin. Compared with ordinary armies, new - type weapons could play a greater role in ninja armies. But not all of them were suitable. After reaching the Jonin level, ninjas didn't need these at all. Instead, exoskeletons or steel armors could greatly enhance their strength. But Haruki wouldn't give up on ordinary armies. Mainly because there were too few ninjas. The Fourth Ninja World War Coalition only had about 80,000 people. If Haruki could have hundreds of thousands or even millions of ordinary troops equipped with new - type weapons, wouldn't he be invincible in the world? Of course, it wouldn't be very useful against Madara Uchiha and his like.

Haruki also talked to the two of them about the problem of Chakra batteries. If this problem could be solved, ordinary people could also use Ninja - Ware. 

After leaving the Research Institute, Haruki went straight to the Anbu, which was now the Security and Intelligence Division.

He had a duties for them to fulfill.

To find the whereabouts of the Sky Ninjas.

After obtaining the new - style weapons, he set his sights on the flying fortress.

Wasn't the technology demonstrated by the Sky Ninjas in the original story just a kind of alternative spaceships?

Once Konoha took over, Haruki believed that his Sky - Space Unit was no longer a dream.

Haruki only vaguely remembered that the Land of Sky was destroyed during The Second Great Ninja War.

Its survivor, Shinno, was also a very excellent Medical Ninja.

He possessed the Medical Kinjutsu of Flesh Activation and Flesh Regeneration, and with these techniques, he could open the eighth gate of the Eight Gates without dying.

To be honest, Haruki was extremely envious.

It was a pity that Might Dai and Might Guy couldn't learn Medical Ninjutsu.

But he could.

The only problem was that Shinno was very hard to find.

This guy liked traveling around the ninja villages and stealing Kinjutsu along the way.

However, that flying fortress was actually the main body of the Sky Hidden Village, hidden beneath the ruins of the Land of Sky.

Two more days passed.

Kakuzu returned.

Only then did Haruki learn that this guy had deposited five hundred million ryo in the Konoha Savings Bank.

Even with his current wealth, he couldn't help but say that this guy was rich.

But he didn't do anything.

Leaving five hundred million ryo in the bank was already a good deal for him.

This money would be used for the construction of Konoha.

As spring passed and autumn came.

Half a year later, the Anbu finally found Shinno's trail.

He appeared in Kiri, the Land of Water.

Haruki told Tsunade and went to the Land of Water alone again.

Since Tsunade became the Hokage, she had been extremely busy.

And her apprentices were also occupied with their own affairs.

Moreover, due to the wide spread of the One Piece story, the Land of Water was quite chaotic and dangerous at this time.

It was more convenient for Haruki to go by himself.
