Spatial Construction · Ninjutsu Prodigy

Uchiha Hara immersed his mind in the newly formed small dimension within the Demon Refining Pot and clearly felt his close connection to this world.

He discovered that the lay of the mountains and rivers, the distribution of earth elements, even the flow of energy through the air—all of it could be controlled with a single thought.

He was the sole ruler here. He was the lord of this world!

"Three square kilometers..." Uchiha Hara looked down over this newborn world. It seemed like just a number, but spread out before his eyes, it was exceptionally vast.

That was already equivalent to the combined area of a large town and its surrounding farmland.

After a brief moment of bewilderment, a powerful urge to plan surged through him.

"I have to plan this properly!" His eyes gleamed as he began drafting a blueprint in his mind:

1. Residence: He had long desired an absolutely private, secure home.

The location would be right at the center of the dimension!

But as a ninja, his way of building a house naturally could not be ordinary. He planned to use ninjutsu for construction. As for which techniques specifically, he would need to look through Uchiha Jiang's collection.

2. Training ground: A fully equipped comprehensive training area was essential.

He needed a deep-water section for underwater training; a broad lake for practicing Fire Release—water and fire clashing would better test his control, while also keeping him from burning things down; a large flat plaza for taijutsu and swordsmanship; and plenty of targets for kunai, shuriken, and archery practice.

3. Farm: Looking at this vast land, the deep-rooted attachment to the soil within his transmigrator's soul was awakened.

"Not growing anything here would be an outrageous waste!" He decided to set aside areas for future crops, vegetables, and even medicinal herbs, achieving partial—or perhaps complete—self-sufficiency.

The final plan took shape in his mind:

A hundred-meter hill would rise at the center of the dimension, its terrain rolling enough to serve as a three-dimensional training ground.

He would draw out a water vein to form a clear spring flowing from the mountaintop, winding through the entire dimension.

At the southern foot of the mountain, beside the water, would be his future home. The flat land before and behind the house, as well as both sides of the river, would be converted into orderly farmland.

The northern side of the mountain would be designated as the comprehensive training area. With the mountain at its back and water beside it, it would be fitted to the terrain with a deep-water section, lake, plaza, and forest target range.

Aside from training, the mountain itself could be planted with fruit trees. Once small animals were introduced in the future, it could also simulate a wilderness hunting environment.

With the plan decided, Uchiha Hara stirred his thoughts.

A stretch of hills rose from the center of the dimension, forming a small mountain.

At a thought, vast wilderness was turned over and transformed into neat rectangular fields, waiting only for seeds to be planted.

A river flowed down from the small mountain, passed through the vast farmland, circled the dimension once, then formed a lake behind the mountain.

Beside the lake, a training ground with flat, hard-packed earth was opened up.

The metal materials piled throughout the dimension—unrefined kunai, fragments of ninja blades, and metal ingots—rose as though controlled by invisible hands. They deformed and melted together in midair, becoming sturdy pull-up bars, parallel bars, dumbbells, and wooden training dummies before landing precisely throughout the designated training area.

Seeing his plans take shape, he could not wait to begin training in this personal territory.

Tai Chi flowed in smooth circles, sword strikes tore sharply through the air, arrows flew from the bowstring to accurately strike homemade targets a hundred meters away, and kunai and shuriken traced tricky arcs through the air... After one complete routine, he felt utterly exhilarated!

The key to that exhilaration was not merely the training itself, but the unrestricted sense of freedom. Whether at the clan grounds or by the Naka River, he had always needed to spare attention for his surroundings, worrying that he might expose his strength or reveal his training process.

But here, he was the sole ruler. He could let loose to his heart's content, try any idea he wished, and never worry about being watched!

With another thought, he instantly appeared at the center of the dimension. As the lord of this world, he possessed the authority to teleport within it.

The grounds had been planned. Next came building the house.

The books and ninjutsu scrolls originally piled here were still stacked like mountains.

Uchiha Hara rummaged through the pile of ninjutsu and quickly found his targets:

C-rank Ninjutsu · Earth Release: Earth and Stone House Technique: Could construct a simple two-story house of earth and stone.

B-rank Ninjutsu · Earth Release: Linked Pillar Houses Technique: Could construct multiple connected rows of earth-and-stone houses at once, commonly used for building camps.

Picking up the scroll that recorded the Earth and Stone House Technique, Uchiha Hara quickly read through it.

Since it was a C-rank ninjutsu, it naturally was not difficult to learn. After reading it once, Uchiha understood everything with perfect clarity: the hand seals, the routes chakra needed to follow through the meridians, the key points of resonating with earth chakra, and more.

He set down the scroll, raised both hands, and formed the required hand seals.

"Earth Release: Earth-and-Stone House Technique!"

Chakra flowed smoothly into the earth beneath his feet. Accompanied by a low rumble, the ground before him rapidly rose and took shape. The outlines of walls, doors, windows, and a roof quickly emerged!

Within only a few breaths, a rather sturdy-looking two-story building rose from the ground!

"It worked? And... it barely seems to have cost any chakra?" Uchiha Hara was somewhat surprised by how smoothly it had gone.

He sensed the chakra within his body and found that the expenditure was far below his expectations.

Excited, he picked up the scroll for the Linked Pillar Houses Technique.

This technique had more complicated seals and even more intricate chakra circulation routes.

Yet after reading it, he still felt that it was not difficult at all.

And with the experience of casting ninjutsu just now, he vaguely formed a guess.

This time, he did not even form hand seals.

With only a slight shift of thought, he controlled the chakra within his body to circulate along a specific route while establishing a connection with the earth.

"Earth Release: Linked Pillar Houses Technique!"

Rumble—

In another empty area he had designated, three identically built single-story stone houses erupted from the ground at once, lined up in neat rows!

"!!!" Uchiha Hara froze.

He really did not need hand seals?

He suddenly realized that, after multiple boosts, his talent for learning ninjutsu seemed to have reached an utterly terrifying level!

His powerful [Spirit] attribute was the foundation of spiritual energy, granting him extraordinary comprehension and control.

The completeness of all five elements, especially the organizing, clarifying, and converging qualities brought by filling in the [Metal] attribute, gave him an incomparably thorough understanding of energy structures.

[Elemental Affinity (Blue)] allowed him to communicate with natural energy—especially earth elements—without the slightest obstruction.

The [Spirit Illusion (Green)] talent enhanced his delicate control over chakra shape transformation.

With all these talents layered together, his control over his own chakra had reached an inconceivable level of precision!

To him, the chakra circulation patterns of B-rank and lower ninjutsu no longer held any secrets. He could completely bypass the cumbersome process of hand seals, directly guide chakra through its internal cycle with his thoughts, and activate techniques instantly!

"Casting ninjutsu like this feels a little insufficiently 'Hokage'..." Uchiha Hara suddenly felt playful. He lightly clapped his hands together in front of his chest. "Then I'll add a gesture!"

With another thought, another small house took shape alongside the clap.

Clap his hands, call for something, and it came!

"Hmm, now that's the feeling." He nodded in satisfaction.

To test his limits, he found another A-rank Wind Release ninjutsu—Wind Release: Wind Blade.

This technique already involved chakra nature transformation. It was an advanced technique that highly compressed and sharpened formless wind-nature chakra. It was very difficult to learn, but consumed very little chakra.

He still understood the contents of the scroll at a glance, and its principles were clear to him.

He tried to cast it.

Hiss—

A pale cyan blade of air formed in his hand, letting out a sharp screech as it sliced through the air.

"I can cast it... but," Uchiha Hara said as he sensed the strength of the wind blade and compared it to the scroll's description, "its power is far from being able to cut iron like mud. It's only a little stronger than an ordinary Wind Blade Technique."

He understood.

His ability to cast techniques without hand seals was based on his powerful chakra control, and that powerful chakra control had directly raised his training in chakra shape transformation to the maximum level.

But the power of a ninjutsu depended not only on shape transformation, but also on attribute transformation and nature transformation.

Attribute transformation meant changing a non-attribute technique into wind, fire, lightning, earth, water, and other attributes.

Nature transformation meant further strengthening a technique on the basis of attribute transformation.

For example, giving wind-nature chakra the quality of sharpness, fire-nature chakra the quality of extreme heat, water-nature chakra the quality of high pressure, and so on.

A-rank and higher ninjutsu had already begun to involve chakra nature transformation, and their power depended heavily on the depth of that transformation.

He had not yet formally begun training in this area, so he could not refine wind-nature chakra to its ultimate sharpness.

In other words, he had the framework of the technique, but the core "quality" still did not meet the standard.

"Nature transformation requires steady effort over time. It can't be rushed." He was not disappointed. On the contrary, his starting point was already far higher than that of other ninja.

Other ninja had to train chakra control, ninjutsu shape transformation, and chakra nature transformation.

He, however, only needed to train nature transformation.

The time, energy, and chakra he saved this way were considerable indeed.

Come to think of it, when he had been looking for A-rank ninjutsu just now, he had originally wanted to use Fire Release. Yet the vast Uchiha clan did not have a single A-rank Fire Release technique.

Had they never possessed one, or had Uchiha Madara taken all the advanced Fire Release techniques with him?

But then he remembered that even Uchiha Madara used B-rank Fire Release, so perhaps Fire Release simply did not have any advanced techniques?

Uchiha Hara also thought that Fire Release was actually a kind of ninjutsu that did not require nature transformation. Its basic attribute alone already possessed terrifying destructive power. Could it be that the Uchiha ancestors had been lazy and never developed A-rank or higher Fire Release techniques at all?

Or perhaps no matter how deeply one developed the chakra nature transformation of Fire Release, it could simply be integrated into basic Fire Release techniques, making it unnecessary to develop separate A-rank Fire Release?

Of course, there was another possibility: by the time others started using A-rank ninjutsu, the Uchiha clan had awakened the Mangekyō Sharingan...

With the Mangekyō Sharingan and Susanoo, who would still play with Fire Release?

Just like Sasuke. After awakening the Mangekyō Sharingan, he immediately seemed to forget how to fight. Earlier, he had fought Deidara blow for blow, with every bit of strategy and calculation in place, his combat intelligence exceptionally high.

But after awakening the Mangekyō Sharingan, it seemed like he knew nothing but Susanoo.

He was getting off track...

For now, finishing the house was more important.

"Earth Release: Earth-and-Stone House Technique!"

He cast this C-rank ninjutsu again and again, growing rather addicted to it.

Earth Release drew upon the power of the earth, so its chakra consumption was relatively low to begin with. With his current chakra reserves and recovery ability exceeding that of an ordinary Chunin, he could fully support this continuous casting.

With every cast, he made slight adjustments to the structure and details. The houses went from crude earthen structures to increasingly sturdy and orderly buildings, even gaining a few simple decorative lines.

By the fifteenth casting, a two-story stone house that looked sturdy, practical, and aesthetically pleasing was finally complete.

"Hmm, this is about my current limit. To optimize it further, I'll need to deepen my attribute transformation!"

Uchiha Hara knew that Earth Release had many attribute transformations and could develop into various release techniques such as Stone Release and Steel Release. The house he had built now had no issue with precision; what it lacked was entirely in the materials. There was no rushing such a thing.

He first built a sturdy library, sorted all the books and ninjutsu scrolls into categories, and neatly arranged them inside.

Next, he built a large warehouse and stored away the remaining enormous sum of cash, gold, silver, and all kinds of metal materials.

Only then did he carefully construct his own single-person villa.

This villa was made by using the Linked Pillar Houses Technique to shape three connected two-story buildings, then opening up their passageways. Calling it a villa was generous; in truth, it was just a small two-story house.

But at least it was much bigger than his house in Konoha.

Afterward, he took out all the furniture he had previously placed into the Demon Refining Pot while renovating the training ground—beds, tables, chairs, cabinets, and more—and arranged them according to his preferences.

The only flaw was that the windows had no glass.

But in this small world under his control, even the wind needed his permission to blow. Whether there was glass or not hardly seemed to matter.

Standing before the window of the villa he had built with his own hands, looking out at the small world that was beginning to take shape, Uchiha Hara's heart was filled with an unprecedented sense of satisfaction and security.

This was his starting point, and it would also become his strongest support in the future.
