A Personal Core System Emerges

As the new year began, minor skirmishes between other nations continued after the Land of Wind and the Land of Fire signed a treaty, but no large-scale war broke out.

Still in the training ground, Shuichi had all sorts of props laid out in front of him, such as oddly shaped ironware, sand, and metal. These were the items he used to experiment with Magnet Release.

In less than two months, after a long period of invasion by Shukaku's chakra, he was able to use Magnet Release in its basic form, although this Kekkei Genkai was slightly different from the others.

First, compared to the effects of Synthetic Explosion Release, Magnet Release has a negligible impact on physical attributes, or rather, its "side effects" are very small, and it is not difficult to learn.

After practicing many times, Shuichi also discovered some tricks.

It should be said that everyone's chakra has different properties, and there will always be some objects in nature that are compatible with one's own.

For example, he speculated that Rasa's chakra might be very compatible with gold, while Gaara was better at controlling sand because his mother's chakra was in his body.

In the process of manipulating various objects using Magnet Release, he also discovered the user's requirements for this Kekkei Genkai.

Picking up a thin piece of metal, Shuichi immediately used his chakra to control it. The metal piece flew around in the air, and from a distance, it looked like a rather agile little insect.

"It seems that using Iron Sand is indeed hopeless; the quantity is insufficient to form a large-scale operation, and thus its power cannot be demonstrated."

Magnet Release is a Kekkei Genkai that demands a high level of skill from the user. At the very least, there are strict requirements for the amount and strength of chakra. While it may not be comparable to Tailed Beast, it must at least be several times stronger than a typical Jonin.

This can be seen in Gaara, whose chakra reserves are astonishing, despite being Jinchuriki.

However, when he appeared in the original work, the total amount of sand completely under his control was the same as the amount of the ball that could absolutely defend against him.

As the plant ages, the amount of sand in this area will increase.

Users of Magnet Release must cultivate and manipulate objects with chakra over many years, and all their strength comes from this. Overall, this clashes with Shuichi's style, so he would definitely not choose it as his primary method.

Actually, among all that random stuff, he found something that really suited him—it was sand...

"Sand Binding Coffin!"

Shuichi looked at the tree trunk ahead with a slightly murderous gaze, stretched out his left hand with his five fingers spread, and then clenched it tightly.

A cloud of White Sand rushed across the ground at great speed, enveloping a wild spider the size of a palm.

Perhaps sensing danger, the spider could be vaguely seen struggling with its many legs, but it was completely unable to move the dense White Sand.

"Sand Burial!"

"Giggle... Pfft!"

After a period of squeezing, Shuichi controlled the sand back to his side and found that the spider was dead beyond recognition, while his White Sand was covered with a lot of green sap, the stark color contrast was very unpleasant to look at.

"This is disgusting! The control device has been used repeatedly in combat for over a decade. Who knows how much stuff it must have gotten on it? It's incredibly filthy, and yet you have to wrap it around yourself for defense..."

That's right, Shuichi's "destined" object is white Sea Sand, which he collected from the most beautiful beach on the coast of the Land of Fire.

The sand in the desert of the Land of Wind is quite different from that in the sea. It is fine sand left behind by countless waves, the kind that feels very soft when you step on it when you play at the beach in your past life.

"My father's specialty was Water Release, so perhaps I inherited some of that trait from my chakra," Shuichi thought to himself.

These White Sand are lighter and finer than those in the desert, and may contain a significant amount of Seawater.

He obtained a total of about 3 liters of water, then nurtured it with his own chakra for many days, and finally its power was as shown in the demonstration.

So how exactly is Magnet Release used?

Shuichi fell into deep thought. To him, the offensive capabilities of Magnet Release were utterly insignificant, so it could only serve as a defensive and supportive tool.

In this way, the demand for sand will not be too great; given his chakra reserves, he only needs to use a small portion on a daily basis.

"Having given up offensive capabilities, we need to find a way to maximize our defensive and support abilities..." Shuichi thought for a while and decided to try it out immediately.

He immediately controlled the White Sand to drift away into the distance, and as it flew through the air, it continued to disperse, the sand so fine that it was almost invisible to the naked eye.

He sent a Shadow Clone to walk at a distance, and Shuichi tested the use of sand for physical perception. He found that the effect was quite good, and it could clearly detect things dozens of meters away. It could complement his X-ray vision to a certain extent.

"We still need to work on defense, flight, and mobility."

The advantage of Magnet Release is that it doesn't require Hand Seals, and it's best to combine it with your own fighting style. Even if it doesn't significantly increase your raw strength, having more techniques is always beneficial...

After thinking about it this way, Shuichi's mind suddenly clicked, "I'd better go give it a try."

A few days later, he arrived at the arena carrying a green Jonin Vest and ninja shoes, which he had specially ordered for himself.

The vest looked just like any other vest, but it was hollow inside. Shuichi quickly filled it with a lot of White Sand and then put it on.

"Pfft pfft..."

He slapped it twice and found that the effect was quite good. Now his upper body was incredibly fleshy, and even Jonin skilled in swordsmanship could only scrape the skin at most when he cut it.

This was modeled after Gaara's close-fitting Sand Armor, but it's several times thicker. In addition, Shuichi uses super-high-quality chakra to control the dense White Sand, making its defensive power extremely terrifying.

"Okay, it would be best to get more sand, and hide the rest in your arm guards, short-sleeved shirt, and shorts." Shuichi had already figured out how to use his unique White Sand Magnet Release technique, which was a combination of defense and support.

Now that the defense is resolved, the next step is to address the support effects. He has already figured this out: he will use Magnet Release to enhance his Body Flicker Technique while simultaneously providing him with Flight ability suitable for combat.

Pick up the ninja shoes. The insoles are thicker, and the space inside is used to hold a small amount of sand, so that there is something to control at several balance points all over the body.

After changing his clothes, Shuichi immediately started trying them on according to his own ideas.

"Brush!"

After activating the Body Flicker Technique, he moved swiftly through the air, controlling the sand on his body to shift to the side. Although this did not completely interrupt his forward momentum, it still created a strange arc.

"It's too fast, it's a bit hard to control."

The inertia from high-speed Body Flicker Technique is too great; it seems unrealistic to attempt a ghost-like, drifting movement.

This idea failed for the time being, but Shuichi was not in a hurry. He quickly began to test the effects of Magnet Release in aerial combat.

The specific method involves creating small Aerial Footboard with sand in a short period of time to perform actions similar to Sky Walk, which can be used in conjunction with the Flight ability using Magnet Release.

After manipulating the sand clinging to him to lift himself into the air, he suddenly released a small clump of sand at his feet, "Whoosh!"

By performing a Body Flicker Technique while standing on the sand in mid-air, Shuichi quickly mastered the technique. With repeated practice, fighting ninjas with Flight ability would become much easier.

"There are still some drawbacks; releasing sand into the air reduces the amount used each time."

After the drill, he even had to follow the residual chakra in the sand to retrieve all the fallen items, which was quite troublesome.

This ability was specifically designed to counter Ōnoki and Deidara, so it probably won't be used much in normal circumstances...

After repeatedly experimenting with all sorts of fancy ideas, Shuichi finally realized with dismay that Magnet Release, apart from making his physical body much "harder," didn't offer much improvement in other aspects.

"I'm now proficient in Explosion Release and Magnet Release, and there's definitely a lot of potential left to explore. How exactly can I combine them for use?"

After experimenting with Magnet Release for a while, his chakra was quite depleted, so he lay down on a rock to rest. "There's not much room for improvement in conventional Ninjutsu. Right now, I'm actually a hybrid of several members of the original Hokage lineage, and my own style isn't very distinct..."

Although he could maintain his rate of growth as he got older, Shuichi always felt a little resentful, because most of his skills were actually just for show.

If a person has no dreams, what's the difference between them and a salted fish?

Just as Minato mastered the Flying Thunder God Technique to perfection, he considered himself even better and wanted to create something to show the Shinobi World how terrifying a "transmigrator" could be.

After lying there for a long time without getting anything in return, Shuichi found himself getting impatient.

The road ahead is long, and he is still so young. As his Ninjutsu skills improve, he will surely have more ideas than he does now.

After figuring this out, he relaxed and decided to take a few days off to adjust his mindset.

Humming a little tune, she was replaying a short film from her past life in her mind. Although the technology in the Shinobi World was advancing rapidly, the daily entertainment activities were definitely very different from those in her past life.

He has been constantly studying Ninjutsu over the years because of his strong curiosity about chakra; otherwise, as someone with terminal Phone Addiction, he would have died of boredom long ago.

"Jingle!"

Inspiration always appears unexpectedly, like a flash of light in the darkness. A bolt of lightning struck Shuichi's mind, and he immediately jumped up from the rock.

After living in the Shinobi World for many years, he had become somewhat assimilated by his environment. Today, a chance recollection of his past life broadened his perspective. "Brilliant! Let's go!"

The next morning, Shuichi his belongings to the Daimyo's Mansion and went straight to the ninja tool shop after entering the city.

Master Sato, an old acquaintance, gets up very early; his body is full of vitality from years of crafting ninja tools.

He had just pushed open the door to open for business when he saw people already waiting at the entrance, clearly having been there for some time.

"Shuichi-kun? You're here so early?"

Sato was somewhat taken aback, completely unexpected that this distinguished guest would arrive right when the ninja tool shop opened. "Is there some ninja tool you urgently need made? Are you going to the battlefield again?"

"Well, no, not at all." Shuichi smiled, his tone excited. "It's just that we really need Uncle Sato to handle the ninja tools personally; I don't trust anyone else with that."

"Hehe, you're too kind. Purple Aurora is famous throughout the Shinobi World now!" Sato beamed upon hearing this. "Come in, let's go to my private studio. I'm full of energy when I get up early."

The two walked together into a house in the backyard. Various tools were neatly arranged against the wall. Even without an open flame, the temperature inside was significantly higher than outside, indicating that Sato was also a diligent person.

Seeing Sato turn on the light, Shuichi didn't waste any words. "Today I need a special ninja tool, and the materials are very precious. It is..." As he spoke, he took out a Scroll from his body, which opened to reveal a pair of long swords with spikes.

"Hiss!" Sato gasped after seeing it. "This is the Thunder Swords Kiba, one of the Seven Ninja Swords of Kirigakure. Shuichi-kun, are you trying to..."

"Yes, I plan to use the materials from this sword to forge my own ninja tools, so the Thunder Swords will be gone from now on," Shuichi said calmly.

Sato examined it as if it were a priceless treasure; this kind of Ninja Blade, Daimyo throughout the Shinobi World, was every swordsmith's dream.

After a moment, he looked up with a somewhat conflicted expression. "This sword perfectly combines Chakra Metal and Lightning Stone. If it's reforged, then its Lightning Element- related special effects will likely be lost..."

Shuichi didn't care at all. "A weapon's reputation depends on the user's ability. Newly forged ninja tools will shine brightly in my hands, becoming a force to be reckoned with in the Shinobi World."

Then he took out several stacks of cash. "This is 300,000 taels of silver as a reward for your hard work. Please accept it, Uncle Sato. And please keep this a secret. I don't want anyone else to know that this Thunder Swords has fallen into my hands."

Sato took a deep breath; the customer had already made their decision, and he wouldn't argue with them.

The thought of forging a divine weapon from such precious materials today filled every cell in his body with excitement; hot breath even escaped his nostrils. His eyes widened as he exclaimed, "What are your requirements, Shuichi-kun? I guarantee I'll create a perfect masterpiece!"

"Hmph, I've already thought it through. I drew up the design last night." Shuichi took out a piece of paper from his pocket and handed it to Sato, who quickly took it and looked at it.

"What the heck?" Sato almost couldn't catch his breath when he saw what was on the blueprint.

He had expected it to be a short sword, a long sword, or a ninja tool like Kusarigama, but what appeared before him was a strange-looking object.

If any other time travelers were here, they would surely exclaim, "Is this a combination of Desert Eagle and R8 Revolver?"

Unable to contain himself any longer, Sato spoke up, "Shuichi-kun, can you explain this? I've never seen a ninja tool like this before."

After recovering from his shock, he had calmed down considerably and quickly realized that this gun-type ninja tool looked somewhat familiar. "This is... an improved version of the Hand Crossbow from previous wars? You're actually building a ranged attack ninja tool!"

"Not bad, Uncle Sato's insight is indeed sharp," Shuichi praised, then handed him a blueprint. "As for how to inflict damage on the enemy, you don't need to worry, that's my exclusive ability."

The drawing shows several bullets that are similar in size but slightly different in structure, and are much shorter than those used in Assault Rifle in my previous life.

Since Shuichi doesn't need gunpowder or cartridge cases, a single bullet is enough, so there's absolutely no technical difficulty involved.

These bullets are mainly made of iron, and can be mass-produced by creating a simple mold.

"I will stay in the Daimyo's Mansion for the next two weeks, and at the same time, I will set up a training ground somewhere in the forest outside to test this ninja tool."

There will definitely be differences between theory and practice. The power and applicability of this Gun-type Ninjutsu Tool will definitely need to be tested repeatedly. If it is really not good to use, we can only make something else.
