Strength Greatly Increased

Kirito added the Enhancement Points to his Wisdom Attribute once more, and the number beside it immediately changed from 4 to 5.

At the same time, his brain was struck by another wave of excruciating pain.

This pain was far worse than the last. In barely a dozen seconds, his entire body was drenched in sweat, his face had turned deathly pale, and he nearly passed out. Blood even streamed from his nose.

But after the pain came an incomparably sweet reward.

He focused and mobilized the chakra within his body.

Soon, a dark-colored chakra with a cold, sinister aura appeared in his right hand.

This was Yin Release Chakra.

"I didn't expect raising my Wisdom Attribute this time would bring such a gain. I've naturally mastered the nature transformation of Yin Release Chakra."

Kirito looked at the mass of Yin Release Chakra in his hand, a delighted smile appearing on his face.

Yin Release Chakra was a type of chakra that created tangible forms from the intangible. At its core, it was a kind of spiritual power.

His increased intelligence had evidently strengthened his spiritual power indirectly.

He then dispersed the Yin Release Chakra, closed his eyes, and carefully experienced the benefits of his increased intelligence.

Before long, he opened his eyes again and slapped the ground.

The next moment, numerous chakra-formed Sealing Formulas rapidly spread across the ground, forming a complex sealing technique in just a few seconds.

Sealing Technique: Triple Lamp Array!

Success.

This sealing technique was an upgraded version formed by stacking the Single Lamp Array three times. Its restraining power was far greater than that of the Single Lamp Array, enough to bind a Jonin for several seconds. Its range was also larger, allowing it to restrain several enemies at once.

However, the Triple Lamp Array was far more complex than the Single Lamp Array.

To put it simply, if the Single Lamp Array was a linear equation, then the Triple Lamp Array was a cubic equation. They were not even on the same level of difficulty.

Before this, although Kirito could successfully set up this sealing technique, it took at least thirty seconds. Such a sealing technique clearly had little use in life-and-death battles measured in seconds and could only be set up in advance as a trap.

But now, Kirito had successfully deployed it in just three seconds, making it preliminarily viable for actual combat.

With another increase in intelligence, Kirito's mental calculation ability had once again improved astonishingly.

If Kirito's mental calculation ability had previously been a single-core processor, it had now been upgraded to a dual-core processor, with greatly enhanced performance.

As a result, Kirito's chakra control had also improved further.

He swiftly completed the hand seals where he stood and used Lightning Release: Lightning Ball.

For a moment, a large number of electric spheres appeared—far more than when he had just fought Nawaki.

This proved that his chakra control had improved further. He could now create more electric spheres with the same amount of chakra, the result of improved chakra efficiency brought about by his enhanced chakra control.

Next, he extended his right hand and began to mobilize chakra.

A large amount of chakra immediately spun in his right hand, eventually forming a Rasengan the size of a thumb.

Though this Rasengan was small, its power was clearly considerable. The instant it formed, it stirred the surrounding air, creating a tiny whirlwind around Kirito.

The Rasengan was the pinnacle of chakra shape transformation, making it an excellent way to train chakra control.

Thus, Kirito had constantly practiced the Rasengan in order to improve his chakra control.

With his outstanding chakra control, he had naturally long possessed the ability to master this A-rank ninjutsu.

However, as an A-rank ninjutsu, the Rasengan consumed an enormous amount of chakra. At minimum, one needed Jonin-level chakra reserves to use it normally.

Kirito had previously been unable to successfully release the Rasengan due to insufficient chakra.

Now that his chakra control had improved further, greatly increasing chakra efficiency and drastically reducing the unnecessary chakra loss caused by releasing the Rasengan, he had finally succeeded in using it.

Although the Rasengan in Kirito's hand was pitifully small, there was no doubt that he had successfully mastered the Rasengan.

"I managed to use the Rasengan with ordinary Genin-level chakra reserves. I wonder where my chakra control ranks in all of Konoha now. It shouldn't be too low, right? Hehe."

Looking at the tiny chakra sphere in his hand, Kirito smiled faintly, unable to stop a hint of pride from rising in his heart.

With such exceptional chakra control, learning all kinds of ninjutsu would be twice as effective for him in the future. And when using ninjutsu, he could greatly reduce chakra consumption, indirectly increasing his chakra reserves.

Kirito did not remain pleased with himself over mastering the Rasengan for long. He quickly dispersed the miniature Rasengan, closed his eyes, and began resting while refining chakra.

A few minutes later, he opened his eyes again and took a Summoning Card from his person.

Summoning Jutsu: Release Technique.

The next second, an iron rod wrapped in a large amount of iron wire appeared on the ground.

"Let's give it a try. I feel like it'll work this time."

Kirito looked at the strange iron rod on the ground with anticipation, then picked it up and released a large amount of Lightning Release Chakra.

In an instant, under Kirito's control, the Lightning Release Chakra clung to the iron rod and flowed along the countless iron wires wrapped around it.

During the process, the Lightning Release Chakra transformed into a high-voltage current.

Dazzling electric sparks immediately burst from the iron rod.

Before long, some black iron sand began to emerge from the ground and float in midair.

"Looks like it worked."

Kirito watched as black Iron Sand continuously burrowed up from the ground, his heart filled with joy.

By using the principle of electromagnetism, then using Lightning Release Chakra to simulate the process of electromagnetism, and finally relying on powerful mental calculation to control the magnetic field, he could ultimately manipulate the Iron Sand within the earth.

This was the Magnet Release Ninjutsu Kirito was currently attempting to develop.

Ever since he had successfully cultivated Lightning Release Chakra, he had begun researching this Magnet Release Ninjutsu.

To that end, he had been diligently studying electrical science.

Unfortunately, the magnetic field created through electromagnetism was simply too difficult to control, and he had never succeeded.

That was only natural. Normal Magnet Release produced a special chakra with magnetic properties within the human body. One only needed to attach that chakra to Iron Sand to manipulate it with ease.

But Kirito relied on the magnetism generated by electromagnetism, making the process far more complicated. It required not only exceptional chakra control, but also powerful mental calculation.

This was the first time Kirito had felt able to control the magnetic force generated by electromagnetism without much strain.

Next, Kirito began trying to manipulate some Iron Sand into simple shapes—Kunai, Shuriken, walls, and the like.

But after completing only a few simple shapes, he felt weak all over and dizzy.

At the same time, the high-voltage current on the iron rod vanished.

There was barely any chakra left in his body.

"Although my vastly improved mental calculation has allowed me to control the magnetic field created by electromagnetism, my current chakra reserves are still far from enough to successfully complete this ninjutsu."

Kirito forcibly endured the discomfort caused by excessive chakra consumption and sighed helplessly.

However, his eyes were shining with excitement.

The hardest first step had already been taken. From here on, he only needed to steadily improve his proficiency.
