"Really...... Hey, this plug-in is kind of interesting. Naruto played with the newly purchased Shinobi knife in his hand and smiled with a sudden expression.

After today's usual task was completed, he was a little eager to try his new plug-in, and after picking for a long time in the ninja shop, he finally chose this ninja knife according to his feel.

The ninja knife used by the ninja is different from the samurai's sword and taito, although it is the same single-sided blade, it has almost no arc and is slightly shorter.

This is because of the special fighting style of ninjas, a weapon that is too long is obviously not suitable for agile ninjas, and it will affect their usual movements when they are carried, and it is very rare to carry it directly on the waist like Sasuke in the back.

The one Naruto bought was shorter than the ordinary Shinobi straight sword, after all, with his current height, buying a normal one was no different from carrying a katana.

After buying it, he went to the stream where he usually practiced and experimented, and after scourging the nearby wooden stakes, it confirmed his previous conjecture.

Naruto was sure that although he called the sudden plug-in "weapon mastery", there were still obvious differences between the different weapons.

For example, the three weapons he has come into contact with so far are the hat samurai's sword, the decapitation knife that never beheaded, and the ninja straight knife in his hand.

He found that in addition to the ability to master the use of these three weapons in his hands, there were actually some obvious differences in proficiency.

It is very interesting to find that the smoothest or most confident in his hand is actually the samurai's sword, and then the current shinobi knife and finally the decapitation broadsword.

Among them, the feeling of hitting the knife is not very different from the shinobi straight knife, the reason may be that the two weapons are relatively similar in appearance, but when it is the turn of the decapitation broadsword, the difference is quite obvious.

Thinking back to the two rounds of death sword dance that day with a decapitating broadsword in his hand, Naruto knew that such power was great, but he was facing those rogue ruffians who didn't have chakra, and if it was a duel between real ninjas, he shouldn't have been confident in this move.

The flaw of the dancing broadsword is too big, almost entirely relying on the weight of the broadsword itself, with the help of the centrifugal force generated by the left hand kunai fixed ground to cause damage, which is equivalent to every shot is an unreserved attack with ten layers of force, which is too risky in a ninja battle, especially when facing opponents of the same level

This is also the main reason why he did not take this decapitating knife for himself in the end.

By comparing the proficiency of the three weapons, Naruto found that the so-called "weapon mastery" was obviously more inclined to the "agile" one-handed weapon, and the "power" heavy weapon was a little reluctant to mean it.

Although he wasn't quite sure if there was a reason why his body wasn't fully grown, overall, he was quite satisfied with having an inexplicable new plug-in, which undoubtedly greatly increased the thickness of his tactical reserves, allowing him to have more options when dealing with different battles in the future.

The regret is mainly focused on the fact that some of the ninja's ninja equipment is obviously no longer covered by this plug-in.

Just when he was in the ninja shop today, he touched it around, such as the wind demon shuriken, special kunai, chain scythe and other ninja tools that were slightly less popular than the ninja straight knife, but they didn't make him have any "resonance", it seems that the coverage of this plug-in can be judged as a "conventional one-handed weapon" first.

"If only I could get a ninja knife of chakra metal." After playing with it for a while, Naruto inserted the ninja knife into the scabbard behind his back and sighed a little longly.

Obviously, he is the natural affinity of the wind attribute, and with this somewhat sudden "plug-in", the wind escape chakra attached to the knife body is simply unreasonable.

It's a pity that chakra metal is not so easy to get, and even Naruto should have never heard of this kind of thing if he doesn't have a plot memory, because there are many ninja shop owners in the village who don't know chakra metal, even if they meet one or two who know, they also say that this thing is priceless and marketable, and it basically doesn't exist on the market.

It's no wonder that a wind attribute ninja of such a level as Tuan Zang in the later part of the plot has to "enchant" the weapon in that laborious way, Asma is worthy of being the son of the third generation, at least in terms of equipment, he is actually more arrogant than Tuan Zang.

The reason why Naruto wants chakra metal is not unrelated to his recent breakthrough in the change of the nature of the wind escape chakra, maybe he has really grown, and it is more likely that the "shadow clone cultivation method" is indeed a bug, and his related practice has now entered the end, and cutting off the waterfall is just around the corner.

This kind of progress really surprised him, you must know that it has only been about a month since he started to practice the nature of the change, which is simply different in speed compared to his previous cultivation of the Spiral Pill and even earlier climbing trees and treading water.

Of course, the current change in nature refers to the traditional change of the Wind Escape Chakra, which is the kind of change in the nature of the transformation of the Wind Escape Chakra into the extreme light and sharp, showing the ultimate destructive power.

As for what he wanted, the Wind Escape Chakra, which would raise its mobility and defense to a higher level, had no clue, which was also normal, after all, in his imagination, it was unknown whether it could be realized in the end.

However, he is very confident, especially this trip to the country of waves, and the fight with Bai can be said to have inadvertently proved the feasibility of his idea.

This point starts with Shiro's ice instantaneous body, and Shiro has fought a total of two times before and after, and Shiro himself has used the ice instantaneous body more than once to attack or dodge his attack, especially in the end, Shiro can block the body one step earlier than Kakashi, who has the Thunder Chakra stimulation cell, and this technique is even more "indispensable".

And Naruto has seen it so many times, and he also understands this arithmetic.

The so-called ice instantaneous body does not refer to the technique of transferring in the ice cube like the [Magic Mirror Ice Crystal], let alone the teleportation like space shuttle, its essence is actually the control of the friction under the feet, this is an instantaneous technique that can only be performed by Shiro, which is much more clever than Naruto's own [Chakrati Longitudinal Technique].

The principle is that at the moment of high-speed movement, the chakra under the foot turns into an icy nature, creating a thin layer of ice attached to the soles of the feet to reduce the friction between the feet and the ground, which is very simple and pure Newtonian mechanics application, right?

However, the principle is very simple, but in fact it is a skill that requires years of practice to master, you must know that it is not simply a layer of ice on the soles of the feet and the end of the job, it requires extremely precise and fast chakra control to constantly switch between the condensation and dispersion of the ice, the slightest mistake, the consequences in battle are simply unimaginable.

After all, it is not enough to reduce the friction under the feet, it will only make people slip, and I am afraid that they will not even be able to stand steadily, and the white ice instantaneous body can be said to be a real friction control skill, quite the essence.

And Naruto was more sure of his thoughts after understanding this, just as the ice in Shiro's hands not only showed "freezing", the wind should also be the same, and even the wind should be more flexible and changeable, the clouds are impermanent, the wind is phaseless, the wind can be a storm that destroys everything, or it can be a gentle touch over the head of the fawn, it will not and should not form an inherent pattern.

Naruto is convinced that even if it is difficult to operate in practice at the moment, he believes that as long as it is successful, there will be no upper limit to this new chakra change.

So even if the road is long and obstructive, he won't give up, not only because of the previous reasons, but also in order to live a different Naruto in the case of the Nine-Tails God, he is really tired of everything that happens repeatedly in the plot, which makes him feel like a ridiculous existence like a marionette.

He thinks that he shouldn't be a careful "tinkerer" around the plot, if that's the case, even if he survives to the end, what's the point of becoming the seventh generation Hokage? What's more, he himself is different from the original Naruto, whether it is the so-called Will of Fire or the title of Hokage, he has no interest in it at all.

Since God has given him a chance to say goodbye to his ordinary life, why not seize this opportunity and live a magnificent life that is different from his previous life, and even more different from the original Naruto.

Even if this life may not be enthusiastic enough and not positive enough, he has to live a different wonderful life.
