"So Mr.Tazuna, could you care to explain why shinobis are targeting you?" Kakashi said clamly, after his Genin team take care of demon brothers and tied them to a tree after they knocked them down.
While it was challenge for them where they were covered with bruises, yet with combine might of all three of them was enough to defeat them.
Seeing their was no point of lying, Tazuna revealed the truth, confessing it was B-rank mission he could not afford, so assigned it as C-rank to reduce cost.
Kakashi like the original pretend to go away, and Naruto unlike the original, did not argue, even though he felt great at defeating someone higher rank than his.
Tazuna, out of desperation, pleaded not to leave and even told the whole truth of the situation this time which even surprises Sasuke, as Tazuna revealed a detail that was not known before.
'So main income of this island which Gatō control was not just commerce and trade, but also selling chakra metal?!'
Chakra metal was extremely rare in nature and had high demand to make the one of the best weapons, as they were quite durable and good conductor of chakra.
'The land is even more valuable than what Hokage told me.' Kakashi thought trying to hide his expression, where combine with Land of Waves approximaty to Land of Fire and availability of Chakra metal, Land of Waves was too valuable to left alone.
'Even if its A or even S rank mission later on, the effort is worth it.'
"Hope you are not making this stuff or I can blacklist the nation." Kakashi said nonchalantly, making Tazuna sweat even more.
Naruto and Sakura did not understand the significance, but knew it was important if Kakashi agreed while Sasuke imagine how good it would be for Sakura to have brass knuckle that is made of chakra metal, as he remembered she was good at concentrating chakra on his fist like Tsunade to deal the damage.
After a brief discussion, Team 7 resumed their journey while guarding Tazuna.
After a while, like Sasuke predcited, they were greeted by a tall and noticeably muscular man with light grayish skin, short spiky black hair, dark brown eyes, and small eyebrows. He was normally seen wearing bandages like a mask over the bottom half of his face. He wore his forehead protector sideways on his head and was shirtless, with his chest only covered by a belt to which he attached his large sword, wearing baggy pants with the striped pattern typical of Kirigakure and mimetic wrist-warmers extending up to his elbows, with matching leg-warmers.
'Yup this is Zabuza alright.'
Just like in anime, he repeated the same words to Kakashi and Team 7.
However, their fight, was one-sided since Kakashi was serious after knowing detail from Tazuna.
Kakashi who knew Zabuza, did not hesiatate to cut in Kubikiribōchō using Raikiri after quickly using Body flicker on him, leaving Zabuza no chance to use Hiding in Mist Technique and Kakashi spread lightning chakra all around the place, preventing Zaubza use his any jutsu where Zabuza would otherwise be electrocuted swiftly, all thanks to Raijin no Ken which was now better hidden in his left leg.
Zabuza felt bitter that he understimated Kakashi who didn't even use his Sharingan and felt bitter that he did not prepare to use his demonic state in advance.
Seeing the situation, Haku, who was wearing Kiri hunter-nin uniform Zabuza gave, quickly paralyzed Zabuza using senbon to make him appear death.
Sasuke looked at Kakashi and wondered how did he go so much chakra all of a sudden.
With his 'one tomoe' Sharingan, he was even more flabbergasted, noticing Kakashi had extra 'chakra points' on his left leg.
Sasuke did not know Kakashi left leg had Raijin no Ken, because chakra of Raijin no Ken and Kakashi was now same thanks to intergration done by Kakashi.
"Sasuke, are you alright?" Sakura asked, wondering why Sasuke spaced out.
Sasuke quickly replied: "Nothing, just the fight was too fast."
"I guess Kakashi sensei was called the strongest Jōnin for nothing." Naruto said, who did not know Kakashi previous strength.
After Kakashi had a brief conversation with 'Kiri Hunter-nin', Team 7 followed Tazuna to his house, who lost all thought of underestimating Konoha, seeing how each fight they fought and finished the fight.
***
After arriving in the house, eveyone relaxed except for Sasuke and Kakashi.
Seeing how tense Sasuke was, Kakashi simply asked: "Is he alive right?"
Sasuke simply nod, while Naruto and Sakura was surprised Zabuza survive.
"You guys may not know but, Kirigakure is facing a civil war, which did not cross my mind until few minutes ago, so it would impossible Kiri Hunter-nin to come unless he was actually was an accomplice of his, quite a skill one I must say to fool me or else Zabuza who have died that moment." Kakashi said in front of Tazuna, so that Tazuna feel relieved despite knowing Zabuza was still alive.
Kakashi looked at Tazuna and asked: "When are you going to build the bridge?"
Tazuna told then it would take 7 days to prepare which Kakashi agrees.
Kakashi nod and instructed his team to go outiside.
"So, wouldn't it best to kill Gatō right now?" Naruto suggested, feeling bad for the whole situation.
Sasuke stayed silent, feeling it was futile to resist change, and don't mind just finishing it since the timeline has changed beyond his grasp.
But Kakashi sighed and calmly said: "I wished we could do it but, their are two problem we are facing."
"First, shinobi from the Konoha cannot do it in public eyes or else it would give excuse to other villages to attack Konoha together, saying they were just suppressing the aggressor who would attack them next."
"Second, it must be done from shinobi from other village in public eyes, since any attack on Gatō will assumed to be from Konoha, again giving Konoha reasons to be attacked."
"So unfortunately, protecting Tazuna to build the bridge its best plan we have." Kakashi said, who was helpless in diplomatic issues.
Naruto, understood the sutuation thanks to Sakura educating him, so he only sighed and hoped everything goes well.
"So anyway, since we are staying here for a whole week, I am going to teach you two how to use elemental chakra." Kakashi said while pointing at Naruto and Sakura, since Sasuke has learned how to use 5 elemtal chakra nature, including Earth chakra that took Sasuke five usage of Bunseki whan Kakashi recommend to learn it a week ago.
"Before starting, let me briefly talk about 5 elemental chakra."
Sasuke did not pay attention, knowing simple things until Kakashi touch a part Sasuke was ill-informed.
"Okay lets talk about property each of them have." Kakashi said, who was experienced enough after using 5 of them in seperate ocassion and things he noticed from his comrades and enemies.
"Property of fire jutsu is to burn or melt object and potentially people, which are useful in certain scenario such as for removing evidence, traces or destroying corpse and destroying weapons like sword, kunai etc to render the opponent defenceless."
"But fire can also create smoke, which are recommend to minimise since enemies will notice the smoke trail and use it to their advantage in certain scenario like when you are hiding them from them after using fire jutsu, though their is certain jutsu that use it to the user advantage like Fire Release: Ash Pile Burning, which creates smoke to make smoke screen, good for distraction and to avoid enemies attacks." Kakashi said, remembering Asuma daily use with that jutsu after his former elder brother Shinzo taught him.
"Now wind jutsu has two opposing property: destructive force or cutting capability."
"Due to having two opposing property, it harder to get either one of them, leaving you with nothing, unless you are master of it or use certain weapon like Suna war fan that makes it easier to use only the destructive force property."
"However, unlike other 4 nature, it creates the least sound if only use its cutting property, making it most viable for assassination, its just too bad the cutting property is hardest to get compare to its destructive ability."
"And yeah you know, it additional capability to stregthen fire and water jutsu." Kakashi said and pointed at Sasuke, who usually does it in daily basis since he can not create more fire chakra at certain point, but instead can create wind chakra alongside maximum fire chakra he can create to enhanced his fire jutsu.
"Anyway, now about lightning jutsu, which has both piercing and cutting property, ideal for swift killing, and can paralyses the opponent and even can electrocute them, making it overall ideal elemental chakra nature to use for killing."
"However, it creates the most noises out of the four, hence not ideal in assasination if you want to keep your presense a secret after assassinating one target among the crowd."
"Water and Earth justu on the other hand are both special, in this case that, they both cost far less chakra in certain condition." Kakashi said calmly, surpring Sasuke and Sakura as they didn't thought it would be possible.
Sasuke did not question, since lots of detail was left unsaid in anime, so it was normal for him not to know.
"First of all, in Earth Jutsu, you can either create element just like the other four
or use pre-existing earth present by injecting earth chakra to it, which decreases chakra usage by a good margin where B rank earth jutsu could be less chakra taxing than any fire, lightning and wind C-rank jutsu."
"However, only limitation is that, usually defensive earth jutsu rely on second method the most, or else Iwagakure would have been the strongest." Kakashi said, which Sasuke agreed as planet he lived is covered mostly by land just like in Earth.
"Second, water jutsu, having similar principal like earth jutsu, can rely on pre-existing water by the same method."
"Though, its chakra usage is even lower and both offensive and defensive water jutsu can rely on it, which combines with wind jutsu that strengthens it, explains why Land of
Water is hardest nation to conquer."
"But it also explains why they can't conquer other lands either, since without pre-existing water, water jutsu has the highest chakra cost of all 4 jutsu, where simple C rank jutsu could have same chakra consumption as of high end B-rank jutsu of other four element." Kakashi concluded, where Sasuke find Tobirama Senju even more impressive since he was known to summon water Release: Water Dragon Bullet with one hand sign with no source of water.
Also his impression on Mei Terumī also increases who fought against Madara without water source.
"You can imbued with lightning chakra to give the water jutsu ability to paralyse or electrocute target, but doesn't enhance it, so it not recommend to use lightning jutsu to strengthen water jutsu."
