For four days in a row, Iruka spent the rest of his time in the library except for rest, just because he needed to understand Chakra in depth, and there were various books about Chakra applications and insights in the library, which was of course of no use to ordinary ninjas, after all, they had been exposed to Chakra since they were children, and they practiced while learning, so how could they be unfamiliar with Chakra?

However, Iruka is different, although he can use chakra, but compared to others who use chakra to perform various ninjutsu, his chakra is just a substitute for telekinetic power, used to provide the supernatural power needed to communicate with reality in the spiritual realm, and Iruka doesn't know anything about ninjutsu, after all, ninjutsu and superpowers are completely two different forms of power, and the only thing that is interconnected is that supernatural power is also needed, and other aspects are completely different, how could Iruka understand it from the beginning?

Originally, Iruka thought that only through frequent use of the ability could use the body's adaptability to external stimuli to quickly consume chakra to stimulate the body to increase chakra capacity, but after fighting Itachi once, he found that this method did not work, and later discovered the repulsion of colorless chakras against blue chakras who did not know where the source was, and Iruka temporarily abandoned this method.

After four days of desperately trying to acquire all the knowledge about chakra in the library, Iruka came to a conclusion that was very useful to him, in addition to being almost completely familiar with the regular knowledge of chakra.

That is, the blue chakra can be strengthened by using ninjutsu.

That's right, the problem that the amount of chakra that plagued Iruka before could not be increased has finally been solved, and it is correct to use the adaptability of the human body to achieve the effect of increasing the amount of chakra by constantly consuming and then constantly resuming this cycle, and the reason why he did not increase a trace of chakra after fighting Itachi is because he is not using ninjutsu, but superpowers, that is, only by using ninjutsu can the blue chakra be enhanced.

Another problem that when using the blue chakra, the operation will be hindered due to the relationship between the colorless chakra, and it seems that as long as the blue chakra is not used to use superpowers, the colorless chakra will not be touched, and if it is only used for ninjutsu, there will be no problems.

This is the conclusion that Iruka got after learning the basics of transformation, but the transformation technique consumes too little chakra, so the conclusion is not 100% accurate, and it needs to be verified with other advanced ninjutsu.

"Haa~ It's time to go back."

Iruka closed the thick book in front of him, and then stretched for the first time in a long time, and his body, which had become a little stiff from being inactive for a long time, suddenly made a "pop" sound like fried beans, which showed how long Iruka had been sitting here.

After putting the book back on the shelf, Iruka left the library.

When he came, the sky was clear, the moon and stars were sparse when he walked, and he walked alone on the deserted streets, and there was no trace of waves on Iruka's face, and he was eerily calm.

Approaching an empty alleyway with no pedestrians, Iruka suddenly stopped, as if waiting for someone, and after a while, the sound of clear footsteps came slowly behind him.

"Oh? Did you spot me? I see, this perception ...... No wonder you can perceive the existence of absolute. ”

It was a man wearing a black mask on an orange background, his whole body hidden in a wide high-necked robe, and his long black hair swayed back and forth under the night wind, revealing a strange aura everywhere.

Iruka slowly raised his hand, and Chakra moved to the extreme in an instant, and in less than two seconds, he could analyze all the force fields in this area, and he could use force field control to completely envelop this space at any time.

After doing all this, Iruka asked in a deep voice:

"Who are you? What is the purpose of looking for me? ”

This time is completely different from the last time he faced the dark team led by Itachi, although there was only one person, but Iruka instinctively smelled an extremely dangerous aura from him, compared to facing Itachi, in the face of a strong enemy of this level, any psychological tactics are meaningless, and can only be dealt with in the most direct way.

"The guide who changed this wrong world, as for why I came to you ......"

The masked man raised his hand at the same time, his black gloved palm facing Iruka, and said slowly, "Because you are hindering the right direction of this world. ”

Click!!!

The ground around the masked man suddenly squirmed, and the next moment, four huge spikes rose from the ground, and the masked man didn't seem to react, and was instantly pierced by the spikes.

The battle seemed to be over in an instant, but Iruka's face did not have a trace of relaxation, but became more solemn, because he found that the masked man's body was clearly pierced, but not a drop of blood was shed, and his body was not pierced by the ground, and there was no trace of real penetration at all.

It felt like a stab piercing through his body.

As if to confirm Iruka's conjecture, the masked man's hand shook slightly, seeing this, Iruka was suddenly startled, and quickly operated the force field to lift the surrounding rocks, and then in less than two breaths, the rocks that were pushed up by anti-gravity suddenly cracked, and a rapid sound of breaking wind rushed towards Iruka.

Fortunately, with the cushion of the rocks, Iruka finally had time to react, and directly used his ability to reduce his gravity to a minimum, and then with a force under his feet, his body suddenly flew upwards, and finally stayed in mid-air, after stabilizing his body, Iruka quickly turned his head and looked at the masked man below.

It was basic common sense that the eyes should never take off the enemy's body during the battle, but when he looked over, only the place where he saw the mask man was standing was empty at this time, and there was only a trace of a swirl in place.

"It's over!"

A cold voice suddenly sounded behind him, Iruka was startled, it was definitely too late to turn around at this time, and immediately no longer hesitated, Chakra ran again, and activated the ability extremely quickly.

"Gravitational field!"

The gravity that was acting on Iruka's body at all times instantly increased tenfold, causing his body to fall straight down like a cannonball, and his flesh and blood smashed directly to the ground, instantly sending up a cloud of dust.

"I see, this guy's ability is not to control rocks, but to control the objectively existing [force]......"

The masked man, who stayed in mid-air, unhurriedly withdrew the black iron rod that emerged from his cuff, and then disappeared again in a swirling wave, and the next moment suddenly returned to the same place, and at this time, the dust gradually dissipated, slowly revealing Iruka's embarrassed figure.

Iruka is in a very bad state, not only is his body covered with dust, the green ninja vest is directly scrapped, the exposed skin is full of wounds, his forehead is also scratched, and the blood does not stop, the most serious thing is that ten times the gravity acts on his body, plus the impact force of falling to the ground, which directly displaces his five internal organs, and now he must separate a part of Chakra's ability to stabilize the position of his internal organs, otherwise even if he is lucky enough to repel the masked man, he will die of internal bleeding.

If it was him in his previous life, even if he suddenly used a hundred times the gravity to act on his body, with his precise control, he would not cause any damage to his body, but now he is just a small middle ninja, and the amount of chakra is so small, and he has not systematically cultivated to accurately control a certain amount of chakra, so he can't retract it freely at all, and injuries are inevitable.

"Ahem!!"

Iruka suddenly coughed violently, followed by a sweet throat, and the next moment, Iruka suddenly spurted out a mouthful of blood arrows, which were the blood that stayed in his body, and after spitting out the blood, his face finally looked better, and then he looked solemnly at the masked man not far away.

Although the injury is a bit serious, it doesn't mean that he has lost his combat power, for him who has the characteristics of both a ninja and a superpower, as long as he still has chakra, he can use his ability, and he still has the power to fight!
