The correct way for the Uchiha to rise

Uchiha Kiyoshi speculated that when the Substitution Technique was developed, it was probably intended to be a space-time ninjutsu, but perhaps something went wrong, preventing the developers from completing it. This incomplete space-time ninjutsu, neither useful nor worth discarding, gradually spread and became a survival skill for low-level ninjas.

Even an imperfect space-time ninjutsu has value. Uchiha Kiyoshi guessed that the era in which such a technique was allowed to spread must have been the era of Ninjutsu. Only during that time was there a great development of ninjutsu. Not only the Substitution Technique, but also various bloodline limit families were formed during that period.

Regardless of the circumstances that led to the imperfection of the Substitution Jutsu, Kiyoya Uchiha intended to try it out to see if he could solve some problems, at least enough to allow him to use it normally.

Unfortunately, after researching for so long, Uchiha Kiyoshi concluded that it required an extremely advanced sealing technique, and his own abilities seemed insufficient...

However, Uchiha Kiyoshi did not give up. He secretly noted this down and planned to study it again once he had mastered the sealing technique.

Moreover, to be honest, it's time to put sealing techniques on the agenda. Both have been researching for several years, and the time spent is about the same. Compared to sealing techniques, Uchiha Kiyoshi, with his foundation from his previous life, has made the fastest progress in medical ninjutsu.

Right now, I don't have enough chakra to practice, and my medical ninjutsu has reached a bottleneck. It's time to shift my focus to sealing techniques.

......

Today, after a full day of classes, Rope Tree was also listless.

Unlike Uchiha Kiyoshi, Nawaki was a typical academic failure. It wasn't just a matter of whether he studied seriously or not; his learning ability was also worrying. At the very least, his listening efficiency in class was low.

However, in order to avoid being beaten up by his older sister, Nawaki could only try his best to listen to the lessons.

What? Your sister is abusing you and you want to file a complaint? Go ahead, go ahead, your sister is waiting for you in the Hokage's office! Let's see if the Hokage sides with you or his own student.

In fact, Tsunade's high standards were partly due to Uchiha Kiyoshi.

As the young master of the prestigious Senju clan, it's one thing to sit next to the Uchiha, but to be inferior to them, and even get completely crushed, is something no one could stand to see.

The unfortunate Rope Tree had no idea that his hellish life was entirely thanks to his deskmate.

If things had gone according to the original story, Nawaki would have had to repeat a grade due to his grades, which was arranged by Tsunade.

That's right, he repeated a grade. Who can blame him? He's from a privileged class, the eldest son of the Senju clan, and has an older sister who's a student of the Hokage.

Unfortunately, everything changed because of Uchiha Kiyoshi's arrival.

This is also the first time that Uchiha Kiyoshi has influenced an important character in the original work since he came to this world.

Unbeknownst to Uchiha Kiyoshi, the changes he had brought to the ninja world had already begun without his knowledge.

Today, Uchiha Kiyoshi is going to buy a batch of ninja tools. All the kunai he got for free during special training have broken, so Kiyoshi will have to buy them himself.

This time, besides kunai, Kiyoshi Uchiha also plans to buy some shuriken and senbon.

When Nawaki heard that Uchiha Kiyoshi was going to buy ninja tools, he also insisted on going with him. He had been listening to classes all day and just wanted to relax.

As a poor person with no source of income, Uchiha Kiyoshi could only choose cheap shops. On Nawaki's recommendation, Uchiha Kiyoshi chose a private ninja tool shop.

In Konoha, ninja tool shops are mainly divided into those founded by families and those founded by private merchants.

Among them, the quality of ninja tools from family-owned shops is generally guaranteed, and with the backing of a large ninja family, the quantity of goods is also sufficient.

In comparison, some small, privately-run ninja tool shops naturally do not guarantee quality, but they are cheap.

Of course, the sale of ninja tools and other war supplies in Konoha must be authorized by the Konoha government, and the basic quality is guaranteed.

Therefore, Uchiha Kiyoshi's main target was these small ninja tool shops.

However, Uchiha Kiyoshi, who had never bought or sold such items before, didn't know where to find the best value for money, so he could only listen to his deskmate's opinion.

As the eldest son of the Senju clan, Nawaki naturally had an abundance of pocket money, and he would occasionally buy things for himself to play with. Moreover, in order to avoid trouble from his older sister, he avoided the family businesses and specifically sought out small shops to buy things.

After a while, Rope Tree also became familiar with the affordable prices of the items in that store.

Arriving at the shop recommended by Nawaki, Uchiha Kiyoshi looked at the hundreds of square meters of space in front of him with the sign "Tano Ninja Tool Shop" and wondered to himself, "Did I misunderstand the word 'small' before?"

Turning to look at the rope tree beside him, Uchiha Kiyoshi gave him a look that said, "Are you sure this is a small shop?"

Unfortunately, Nawaki couldn't understand what Uchiha Kiyoshi meant.

However, Rope Tree still provided an introduction to the shop.

"Qing, this shop is the largest private ninja tool shop in the entire Hidden Leaf Village. The product quality is guaranteed, and the prices are very reasonable."

Uchiha Kiyoshi was skeptical, but he still entered the ninja tool shop.

Upon entering, Uchiha Kiyoshi saw the shop owner sitting behind the counter, working.

As for how to tell if someone is the shop owner, well, just look at their clothes. Compared to the staff in other areas, the person behind the counter is wearing a traditional Chinese cheongsam and isn't doing the work of a cashier.

After Uchiha Kiyoshi entered, he looked at the boss's attire and fell into deep thought.

"A cheongsam? This kind of Chinese-style clothing looks familiar. Could this be the future Tenten Ninja Tool Shop?"

Soon after, a staff member came to Uchiha Kiyoshi, asked about his needs, and then led him to the regular ninja tool area.

Hmm! The "Common Ninja Tools" section is basically a cheap goods section. These are all ninja tools made of ordinary iron; they're not specially crafted by master blacksmiths, and are similar to the standard kunai used by Uchiha Kiyoshi.

Since it was meant for practice, Uchiha Kiyoshi didn't need expensive ninja tools, so he naturally went for the cheapest ones. In fact, he valued durability more than sharpness, and after the staff's recommendations, he chose one of the models.

Fifty kunai, twenty shuriken, and twenty senbon were enough for Uchiha Kiyoshi's needs for half a year. Each kunai cost 1,000 ryo, each shuriken 800 ryo, and each senbon 500 ryo, totaling 76,000 ryo. A small portion of Uchiha Kiyoshi's personal treasury was gone, which pained him greatly.

After reluctantly paying, Uchiha Kiyoshi put away the scroll handed to him by the staff.

For customers like Uchiha Kiyoshi who buy ninja tools in bulk, the ninja tool shop also gives away a disposable storage scroll for easy carrying.

Storage scrolls are very expensive; even a single-use scroll costs tens of thousands of taels of silver, so the ninja tool shop naturally wouldn't give them away for free. What they give away are defective products made due to manufacturing errors. These scrolls also have storage functions, but they can only be used once and have a limited lifespan—about a day. After that, the scroll becomes unusable, and the items inside will also be damaged. Therefore, the ninja tool shop gives away these defective scrolls to make it convenient for customers to carry their goods; they just need to return home promptly and retrieve the ninja tools inside.

After receiving the scroll, Uchiha Kiyoshi did not leave immediately, but instead suggested that he wanted to go and take a look at other areas.

Out of respect for Nawaki, a long-time customer, the staff did not refuse. Moreover, he could clearly see the Uchiha clan crest on Uchiha Kiyoshi's clothes. In Konoha, no one dared to impersonate the Uchiha clan crest.

Led by staff, Uchiha Kiyoshi arrived at the upscale area.

Among them, Uchiha Kiyoshi even saw a kunai made of chakra metal.

Of course, it's not entirely made of chakra metal; only a certain amount of chakra metal has been added to the materials, and the proportion is not high.

Thus, the price of this kunai became astronomical, reaching a full one million ryo, which Uchiha Kiyoshi simply couldn't afford.

Chakra metal is a high-grade resource, extremely rare throughout the ninja world. Unlike ordinary metals, chakra metal has excellent chakra conductivity. By adding some chakra metal to a weapon, a ninja can easily coat the weapon with their own chakra, greatly enhancing both attack and defense.

Besides naturally occurring forms, it's said that chakra metal can also be artificially produced. If a ninja completely envelops a piece of metal with chakra and soaks it for an extended period, chakra metal can be obtained. However, this consumes a huge amount of chakra. Maintaining chakra for even a fist-sized piece of metal requires at least an elite Jonin, and this process isn't something that can be completed in a day or two, but rather over a year.

In other words, it would take an elite Jonin several years of all-out effort, without stopping the output of chakra, to obtain a fist-sized piece of chakra metal! This also shows how precious chakra metal is.

"One million taels! You could buy anything, even a sword. Who would spend a hundred taels on a kunai? Nobody would buy it even if it were made of chakra metal."

The staff member next to him answered Uchiha Kiyoshi's question with a smile.

"This kunai is actually displayed here to show our shop's strength and ability to make ninja tools made of chakra metal."

As they spoke, the staff member proudly raised their head.

Uchiha Kiyoshi nodded. Oh, it was an exhibit. He understood. But he still casually asked about his doubts.

"Well, if you do this, you'll end up creating something that nobody will buy. Isn't that just a waste of this piece of chakra metal?"

At this moment, even Rope Tree, who was standing to the side, looked at his deskmate with a puzzled expression. "Aren't you supposed to be pretty smart? Why are you asking such a pointless question?"

"what happened?"

Looking at Nawaki's expression, Uchiha Kiyoshi was baffled, not knowing what was going on with Nawaki's expression.

Seeing that Uchiha Kiyomaru was unaware, Nawaki couldn't help but laugh.

"Qing, I always thought you were quite smart, how come you can't understand something so simple? Even though chakra metal has been added to this kunai, it doesn't mean it's wasted."

Aside from attracting customers, as mentioned earlier, if needed someday, chakra metal can be extracted from this kunai.

Upon hearing Nawaki's words, Uchiha Kiyoshi was also taken aback, and then asked.

"Isn't chakra metal fused with other metals? What, you're saying it can be separated again?"

"Of course, otherwise, with such a limited production of chakra metal, if every bit used reduces the amount, how much would be left? Who could afford to buy it?"

Rope Tree rolled his eyes, unconcerned.

Uchiha Kiyoshi also realized that he seemed to have learned about separation in his previous life, but he just couldn't remember it. However, as a medical student, it's not wrong for him not to remember chemistry, right?

Immediately, Uchiha Kiyoshi seemed to have thought of something, his face lit up with joy, and he muttered to himself.

"Separation, separation... How come I didn't think of that? Hahaha, I see!"

Seeing the erratic behavior of Uchiha Kiyoshi, Nawaki was also startled. Had his deskmate gone mad? He stretched out his hand and waved it in front of Uchiha Kiyoshi.

Uchiha Kiyoshi slapped Nawaki's hand away in an annoyance, but still explained himself, otherwise he was afraid he would really be mistaken for an idiot. The staff member next to him looked at him like he was an idiot.

"Ahem... well, I'm fine. I just suddenly realized something and got a little excited..."

However, Nawaki didn't seem to believe it either. After all, asking such a silly question and then laughing out loud—isn't that silly?

And so, under Nawaki's strange gaze, Uchiha Kiyoshi bid farewell to Nawaki and hurried home.

Due to family ties, Nawaki couldn't escort Uchiha Kiyoshi home, so he said goodbye and went home on his own.

Chapter Sixteen: The Initial Development of Health Preservation Techniques

Uchiha Kiyoshi was quite excited as he rushed home from the ninja tool shop.

"How could I not have thought of that? Separation, there's such a thing as separation!"

Arriving at the study on the second floor, which Uchiha Kiyoshi had prepared for himself, it was actually a room used for research. However, Uchiha Kiyoshi's research here was all theoretical and did not involve any actual experiments, nor did he have the money to prepare such equipment.

All the equipment used for experiments is very expensive. Don't be fooled by the fact that Orochimaru opened labs all over the ninja world in the original work. You should know that all of that costs a lot of money. Besides being known as a scientist, Orochimaru is also a very rich man!

According to Uchiha Kiyoshi's estimate, Orochimaru spent no less than one billion on the construction of the laboratory alone. This figure is astronomical for Uchiha Kiyoshi, who was still struggling to earn a million.

Uchiha Kiyoshi forced himself to calm down.

First, I took the ninja tools out of the scroll. Luckily, I remembered them, otherwise Uchiha Kiyoshi would have had nowhere to cry if these tools were broken.

After arranging everything, Uchiha Kiyoshi began his research.

Uchiha Kiyoshi had been searching for a way to control his body's energy, but unfortunately, after nearly a month, he hadn't found any clues. However, this purchase of ninja tools gave him another idea. Indeed, some things depend on fate.

From Nawaki's words, Uchiha Kiyoshi also found a solution: separation.

Previously, Uchiha Kiyoshi hadn't considered the issue of separation. This reminder, however, made everything clear.

In my past life, I've done similar problems before, all sorts of tricky chemistry questions. Some things can't be transported directly; they have to be reacted into another substance first, and then replaced at the destination.

This line of thinking can also be applied to the problem of controlling the body's energy that Uchiha Kiyoshi has been pondering.

I can't control your movement, but I can control chakra. By transporting chakra to the appropriate location and then restoring it into physical and mental energy, isn't that equivalent to indirectly controlling the movement of physical energy?

With a clear idea in mind, the next step is to try it out step by step. The most troublesome part now is figuring out how to restore chakra to the body's energy.
