Kirito added the enhancement points on top of the wisdom attribute once again, and the number of the suffix suddenly changed from 4 to 5.
At the same time, his brain was once again greeted with a sharp pain.
This time, the pain was much more severe than the last time, and in just ten seconds or so, his entire body was drenched, his face became incredibly pale, and he almost fainted, with a lot of blood coming out of his nose.
But after the pain was an incomparably sweet reward.
He concentrated and mobilized the chakra in his body.
Soon, a black-colored chakra with a cold aura appeared on top of his right hand.
This was the Yin attribute chakra.
"I didn't expect that there would be such a gain after this Wisdom Attribute enhancement, my Yin Attribute Chakra nature is cultivated naturally."
Kirito looked at this mass of Yin Attribute Chakra in his hand with a surprised smile on his face.
Yin attribute chakra, a kind of chakra that created something tangible in the absence of form, was essentially a kind of spiritual power.
The fact that his intelligence had been boosted had obviously strengthened his spiritual power in disguise.
He then withdrew his Yin Attribute Chakra, and then closed his eyes to carefully experience the benefits of his own intelligence being boosted once again.
Not long after, he reopened his eyes before slapping the ground.
In the next moment, a large amount of sealing jutsu formed from chakra spread rapidly on the ground before forming a complex sealing jutsu in just a few seconds.
Sealing jutsu - Triple Light Formation!
Success.
This sealing jutsu was an upgraded version of the sealing jutsu formed by stacking it three times on top of the first series of light formations, and its binding ability was far more powerful than that of the first series of light formations, enough to bind a jonin for several seconds, and the range was greater than that of the first series of light formations, so that it could bind several enemies at once.
However, the complexity of the Triple Light Formation is much greater than the One System Light Formation.
To make an analogy, the one-system light array is just a one-time equation, then the threefold light array is a three-time equation, the difficulty is not the same level at all.
Before this, although Kirito could also successfully set up this sealing jutsu, but it would take at least thirty seconds, such a sealing jutsu is obviously difficult to play a big role in a life and death battle that is counted in seconds, and can only be used as a trap to set up in advance.
But now, Kirito had managed to set it up in just three seconds, and it was already primed to be used in actual combat.
Kirito's mental capacity had once again been astonishingly improved after his intellect had been raised again.
If Kirito's mental capacity was just a single-core processor before, it had now been upgraded to a dual-core processor, with greatly improved performance.
Because of this, Kirito's chakra manipulation ability was also further improved.
He quickly completed his seals in place and used Lightning Release - Lightning Ball.
In an instant, a large number of electric balloons appeared, a lot more in number than when he had just fought Kawaki.
This was the proof of the further improvement of his chakra manipulation ability, he could now create more electric balloons with an equal amount of chakra, this was the result of the increased efficiency of chakra usage due to the further improvement of his chakra manipulation ability.
Next, he extended his right hand and began to mobilize chakra.
A large amount of chakra instantly spun on his right hand, finally forming a thumb-sized rasengan.
This rasengan, although small, was clearly not bad in terms of power, and just as it was completed, it stirred up the surrounding air currents, forming a small whirlwind with Kirito at the center around it.
The Rasengan was the ultimate in chakra form changes, and using it to exercise chakra manipulation was a very good way to do so.
Therefore, Kirito had been practicing rasengan in order to improve his chakra manipulation power in the first place.
With his excellent chakra manipulation power, he certainly had the ability to successfully cultivate this A-ranked jutsu long ago.
However, as an A-ranked jutsu, rasengan consumed a very large amount of chakra, requiring at least an amount of chakra at the level of a jonin to release it properly.
Kirito had previously been delayed in successfully releasing the rasengan due to a lack of chakra.
Now the chakra manipulation ability was further improved, greatly increasing the efficiency of chakra use, drastically reducing the unnecessary loss of chakra caused by releasing the rasengan, and he finally succeeded in releasing the rasengan.
Although this Rasengan in Kirito's hand at this time was pitifully small in size, there was no doubt that he had successfully practiced the Rasengan.
"I managed to make the Rasengan with a normal genin level of chakra, I wonder where my current chakra manipulation power can be ranked in the entire Konoha, it shouldn't be too low, hehehe."
Kirito looked at the tiny chakra ball in his hand and said with a slight smile, he couldn't help but feel a bit of pride in his heart.
With such excellent chakra manipulation now, he would be able to learn all kinds of ninjutsu with half the effort in the future, and when releasing ninjutsu, he could drastically reduce the consumption of chakra, which in turn increased the amount of chakra he had.
Kirito didn't feel complacent for too long because he had successfully practiced the rasengan, he quickly withdrew the miniature rasengan and began to close his eyes to refine his chakra.
After a few minutes, he reopened his eyes before removing a summoning scroll from his body.
Summoning Jutsu - The Art of Releasing.
In the next second, an iron bar with a large amount of iron wires wrapped around it 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 an expectant expression on his face before picking it up and releasing a large amount of lightning attribute chakra.
In a flash, the lightning attribute chakra climbed on top of the iron rod under Kirito's control and flowed along the large amount of iron wires on it.
During the process, the lightning attribute chakra transformed into high-voltage electric current.
Piercing electric sparks suddenly bloomed on the iron rod.
Not long after, some black iron sand began to drill out of the ground and was suspended in mid-air.
"Looks like it worked."
Kirito watched as the black iron sand continued to drill out of the ground, and was inwardly elated.
Using the principle of electricity generating magnetism, then simulating the process of electricity generating magnetism with the help of lightning attribute chakra, and then manipulating the magnetic field through powerful mental computation ability, the final goal was to manipulate the iron sand in the earth.
This was the Magnet Release that Kirito was currently trying to develop.
Ever since he had successfully cultivated the lightning attribute chakra, he had begun to study this Magnet Release.
To that end, he had been working hard to learn about electricity.
Unfortunately, he had not been able to succeed due to the fact that the magnetic field formed by electricity generating magnetism was too difficult to manipulate.
This is of course, the normal magnet release is produce from the human body through special chakra, just need to attach this chakra on top of the iron sand and can easily manipulate the iron sand.
But Kirito relied on the magnetic force formed by the electricity to generated magnetism, the process was much more complicated, and required not only excellent chakra manipulation, but also strong mental computation ability.
This was the first time Kirito felt little pressure to manipulate the magnet release formed by electro-generated magnetism.
Next, Kirito began to try to manipulate some iron sand to make some simple molding, shaping it into shapes such as kunai, shuriken, and walls.
But as soon as he finished a few simple shapes, he felt weak and dizzy.
At that moment, the high voltage current from the iron bar disappeared.
There was very little chakra left in his body.
"Although I was able to successfully manipulate the magnetic field formed by the electro-generated magnetism by relying on my greatly improved mental calculation skills, relying on the amount of chakra I have now is still far from enough to successfully complete this jutsu."
Kirito forced himself to endure the discomfort brought about by the excessive consumption of chakra and sighed somewhat helplessly.
However, his eyes were shining with excitement at the moment.
The toughest first step had already been taken, and all that was needed next was to keep improving the level of application.
