When the chakra tries to attach itself to the katana, there is an irrepressible resistance between the two, just as the positive pole of a magnet meets the negative pole.

After several attempts in succession, Rogge had no choice but to stop this useless work, and temporarily dismissed the idea of learning the Thousand Bird Blade on his own.

And he was skeptical now, even if he had redeemed the Thousand Bird Blade from the system.

Before he found a suitable weapon, he couldn't successfully use the thunder ninjutsu of the Thousand Bird Blade.

Looking at the Kusanagi sword in the system with a price tag of 80 ninjas, Rogge sighed helplessly.

There is such a thing as a nina coin, which is really never enough!

Since there was no way to learn the Chidori Blade for the time being, Rogge immediately set his sights on the Thunder Escape Ninjutsu Chidori Sharp Spear derived from another Chidori.

Unlike the Thousand Bird Blade, the Thousand Bird Sharp Spear can be used without weapons, which is especially suitable for him who is now poor and white.

As soon as he said it, Rogge threw the katana in his hand to a corner of the practice room, and then his right hand suddenly stretched out.

The originally silent practice room, the moment he cast a thousand birds, suddenly became extremely noisy, like a thousand birds chirping in the practice room at the same time.

In addition to the chirping of birds all around him, a white electric current appeared in his right hand as if it were substance, making it look like it was made of lightning.

Although Rogge rarely uses Chidori in his daily life, his mastery of this ninjutsu is not weak at all.

After casting Chidori, he began to try to use chakra to guide Chidori's morphological changes.

Unlike the self-taught Spiral Pill, which has a complete practice phase, he doesn't have a too complete idea of how to learn the Chidori Sharp Gun.

The only thing he was sure of now was that Chidori's sharp spear was a ninjutsu after Chidori had changed form.

The attack range is much longer than Chidori, but the attack power is not as good as Chidori.

From this point, it can be inferred that the Chidori Sharp Spear is to achieve the effect of extending the attack range by sacrificing part of the attack power.

Although he didn't know exactly what the principle was, he had a very bold idea.

In the brief moment when Chidori has not yet taken shape, he forcibly changes Chidori's form by controlling Chakra, making Chidori become longer.

Rogge didn't know if it would work, but it never hurt to try.

Even if it fails, the worst outcome is that Chidori does not succeed in casting it, and at the same time wastes some chakra.

After making up his mind, he lifted the Chidori that had already formed in his right hand and prepared to cast it again.

This time, he deliberately put the speed of a thousand birds on purpose.

When the white current first appeared, he began to manipulate the chakra in his hand, slowing down the formation of the thousand birds, and trying to elongate the thousand birds.

If he hadn't slackened his practice with chakra in the past, he wouldn't have been able to perform such subtle chakra manipulation now.

Under his careful control, Chidori, which was supposed to be shrouded in his right hand, began to slowly lengthen in the direction of his fingers.

It really can!

After discovering that Chidori's form had changed, he couldn't help but feel excited.

Because of his excitement, the thousand birds in his hands, which had begun to slowly lengthen, suddenly became uncontrollable, and then dissipated in the chirping of birds.

After seeing the white electricity in his right hand dissipate instantly, Rogge not only did not show any disappointment, but became more excited.

Although it may have been a mistake, he found that he seemed to have mastered the knack of the Chidori series of ninjutsu.

If Chidori is also divided into four stages like Spiral Pill, then the difference between Chidori-Blade, Chidori-Sharp, Chidori-ryu, Chidori-ryu and Chidori Chibon-derived ninjutsu and Chidori is that the nature or form of the last stage changes.

If Chidori gathers the high-intensity electric current generated by the chakra in his right hand, the right hand becomes like a sharp blade, so that it has a strong penetrating force.

Then the Thousand Bird Blade is to concentrate the electric current on the weapon, thereby increasing the lethality of the weapon.

It's just that the current of the Chidorigi Blade is no longer attached to the body of the ninja, so you need a suitable weapon to cast it.

In the same way, the ninjutsu of Chidori Sharp Spear, Chidori, Chidori Flow, Chidori Chiben and other ninjutsu are only the fourth stage of changing Chidori, so as to achieve the effect of emitting electricity or enveloping the whole body.

There will definitely be differences in the details of the specific operation, but the general principle should be like this.

After clarifying this, Rogge did not hesitate and began to learn the Chidori sharp gun again.

There is a long, long distance between knowing the principle of a thing and whether or not you can do it.

After exhausting all the chakras in his body, he still couldn't successfully complete the learning of the Chidori Sharp Spear.

His only achievement on this day was to extend the distance of the thousand birds in his hand by about one meter.

When the distance of the extension reached about a meter, no matter how hard he tried, he could not continue to extend this length.

Chidori, which is only one meter long, is definitely not a Chidori Sharp Spear, at best it can only be regarded as a Chidori Sharp Sword.

Rog wanted to try something else to see if he could extend the short distance of one meter a little longer, but the depleted chakra in his body discouraged him.

After changing to a chakra control method, Chidori's length changed from one meter to one meter five, and then he once again consumed the chakra in his body.

After recovering the chakra, he didn't even eat breakfast and started his practice again.

Because of the previous two days' attempts, he can now reach the purpose of extending the thousand birds with less chakra, and the extended distance has also been further improved, from one meter five to more than two meters.

Just as he was about to stretch the distance to three meters in one fell swoop, he glanced up at the window.

In the dark night sky, he saw two people who were rising rapidly.

To be precise, I saw two steel suits that were rapidly rising into the air.

This is...... Iron Man and Iron Overlord fought?

After seeing this scene, he decisively gave up his plan to continue practicing, and cast the Flying Thunder God and disappeared into the practice room.

In the next second, his figure appeared on the top floor of the factory where the prototype of the Ark reactor was placed.

He left hundreds of Flying Thunder Divine Spells in New York in order to be able to get to the scene in time for a critical moment, such as now.

Not long after he reached the top floor of the factory, he saw a giant-like steel suit fall from the sky like a meteorite from the sky.

Just when he thought that the Iron Overlord would have a close contact with the ground like a real meteorite, the Iron Overlord regained the power to fly, and then stumbled and landed on the ground without any danger.
