This is my first story. Don't hate for no reason. Will take fair criticism though.

I do not own Naruto or anything related. That goes to Masashi Kishimoto


CHAPTER 25


Naruto spent the last 10 days perfecting the three jutsu he had learned. He practiced using the Rasengan and placing the Gogyo Fuin in quick succession because he knew that if his arm was left inside of Gaara's sand for even a few seconds, it would be crushed just as Yoroi had been. But with the help of his shadow clones, he managed to reduce the time it took for him to activate the Gogyo Fuin down to milliseconds, which was hopefully faster than Gaara coud react. But now, with only one week before the Third Exam and therefore invasion, it was time to plan. He had been preparing a few seals to distribute, and a barrier or two to place. He just hoped that his Jiji would accept them.

Getting out of bed Naruto got ready for the day before Jiraiya would pick him up. It was about 9 in the morning before Jiraiya knocked on his window. Naruto simply sighed and began packing up his plans and ideas into one large seal. After he walked out his front door then locked it behind him, "Come on Jiraiya." Jiraiya walked around the side of the building to catch up to Naruto as he walked down the stairs of his building. Walking side by side, looking very similar due to the large scroll attached across their backs. Soon they arrived at Hokage Tower but weirdly Jiraiya began to walk up the side of the building making Naruto ask, "What are you doing Ero-sensei?"

"Going in through the window of course!"

Naruto sighed but walked through the front door and up the stairs. Knocking on the Hokage's door he heard a shout, "Come in!"

Opening the door he saw Hiruzen sitting at his desk and Jiraiya sitting on the windowsill.

"Hey Jiji!"

"Hello Naruto, you mind telling me what this meeting is about. I was quite confused and concerned when Jiraiya told me this concerned village security."

Naruto quickly unsealed a piece of sealing paper out of his forearm, and threw it to the wall saying, "Well yeah, after Jiraiya told me about the Invasion," Hiruzen turned to Jiraiya at this with a glare, "I figured I could help with my seals…or my biju."

Hiruzen turned back with a raised eyebrow. "What do you mean?"

"Well in the Third Exam my first opponent is a jinchuriki, and Jiraiya figured he will be crucial to the invaders' plan."

Hiruzen nodded in acknowledgement, "Fair enough, but how could you help?"

"Well during the exam I would seal off the jinchuriki from his biju using the Gogyo Fuin."

"My technique?"

"Yeah. It would mean one less thing to handle. But other than that mostly just seals and barriers." Naruto took the large scroll of his back and unfurled it. From the first section Naruto unsealed 4 slips of paper and a map.

"This is a barrier that I made, the Kuro Kyushu Kekkai (Black Absorbing Barrier). It absorbs most jutsu and uses the chakra to power itself and heat itself up making it hot to the touch from the outside. I figure we could use it to protect certain buildings like the archives or the academy or the Hokage tower."

Hiruzen inspected the seals and thought about Naruto's suggestion, "Any downsides, or weak points?"

"Yeah, two things actually. It's actually pretty physically weak before it absorbs enough chakra. This includes doton jutsu because they tend to be more physical. And even though it will absorb the chakra, it wouldn't be able to take the blow until it's absorbed enough. However one C-rank jutsu gives it enough charge to withstand the basic attacks of kunai, shuriken, punches and kicks. Second weakness is that it can be overloaded, too much chakra will make it shut down, about 3 S-rank jutsu worth in total.

"So a chunin inside the barrier could charge it with one or two c-rank jutsu, any chakra nature except doton, and it could withstand most attacks?

Naruto nodded, "Exactly. It takes about one D-rank worth of chakra to activate then one C-rank's worth of chakra for a basic amount of strength. But after an B-ranks worth of chakra the barrier would be strong enough to withstand exploding tags, and durable to take most doton Jutsu. So most chunin could activate it to working capacity."

"But what if it were to break?" Hiruzen questioned.

"It doesn't really break, it would just let the attack through the barrier instead of repelling it. So if it wasn't strong enough someone could force their way through. But it wouldn't break.

Hiruzen once again looked over the seal, and reviewed Naruto's notes of it. Then after a minute he smiled, "This is very good Naruto, I like these barriers and will definitely implement them, do you have any other seals?"

Naruto smiled back, "Yeah! A lot of it is just different barriers that do different things, but other than that just two things. First is more combat related. I thought that I could apply some chakra storage seal on some of the shinobi, have them store away some of their chakra so that during the invasion they would have an extra supply of chakra."

"That makes sense, but I would assume that users would suffer from chakra pill poisoning, similar to consuming too many chakra pills."

"They wouldn't because it's their own chakra reentering their system so all it would do is let a shinobi stay in the fight for longer."

"Sounds great but how would you place them all?"

"I wouldn't need to. I could have my clones mass produce them, by placing them on sealing strips, then you could distribute them."

"That makes sense, but then who receives them?"

Naruto shrugged, "I don't know, that's up to you but I can make as many seals as you need."

Hiruzen nodded, "That's acceptable, what about the second seal?"

"Well this one is more defensive focused." Naruto unsealed a slip of paper from a different section of the paper, "This is a durability seal. It increases the durability of an object by a set amount, however the larger the object the less of an effect it has. So on a katana it would make it 5 to 10 times as durable, but on something as large as the Konoha Wall, it would only affect it by maybe one percent."

Hiruzen gave a questioning look, "So how would it help?"

"Because they're stackable," Naruto explained, "Each one would increase the durability by a set amount. And if enough are placed, let's say one seal every few feet, then the wall could be three to five times as durable."

"Which would make it much harder for any invaders to break through them."

"Yeah and if I were to place a chakra disrupter seals too no one could climb or walk up it either!"

Hiruzen smiled and continued, "I like your ideas Naruto, let's implement them."

"Isn't my student great!" Jiraiya grinned as he wiped a fake tear, "Already considering village security."

Naruto rolled his eyes, "Save it ero-sensei, you've only taught me for three weeks."

"You wound me kid, you wound me."

-two days later-

Once again Naruto returned to the academy. He thought that after his graduation he wouldn't have to, but duty calls. Walking through the doors Naruto slowly walked the halls until he arrived at the principal's office. He knocked on the door and walked in once he heard the man inside call out, "Come in!"

"Good morning Hasakuro-sensei," Naruto started but was interrupted, "What are you doing here?"

The principal glared at Naruto and asked, "I thought I wouldn't have to deal with you anymore after you graduated."

"I apologize but as long as I'm not interrupted I should be out of your hair by noon."

"Fine, what do you need?" The man grunted.

"I was directed by the Hokage to place seals around the perimeter of the Academy as a form of protection in case of attack or invasion."

"Why would he ask you?" The man questioned.

"Because I am the only person who knows how to make this seal."

The man grunts, "Fine, whatever. Just place them and go away."

"Hold on. There are some minor instructions."

"What are they?"

Naruto begins to write on a seal, "Well there will be an activator seal on your desk. All you need to do is channel chakra into it. After that the seal will activate and a barrier will form around the Academy. But to get it fully functional it will need to absorb more chakra. You can do that by channeling more chakra into the activator or literally using a jutsu on the barrier, except doton. It will absorb the chakra to power itself. Roughly a D-Rank and a C-ranks worth but the more you put in the stronger it will get. My suggestion is to use at least a B-ranks worth of chakra and you'll be safe, though using more is okay."

"Anything else?"

"Yeah, to deactivate the barrier just press the activator into the barrier, the chakra will collide with itself and collapse. The seal is reusable so don't throw them away. Take this, it's instructions just in case you forget."

The principal took the paper and the seal then waved Naruto off, "Cool. Thanks, now go away. I have work to do."

Naruto bowed, "Okay, have a nice day sir." Then he walked out.

-four days later-

Naruto collapsed on his bed. The first day he was running around the village placing three barrier seals, one around the academy, one around the archives, and the last one around the Hokage Tower, each of which took nearly four hours. But while he was doing that he had 150 clones mass producing chakra storage seals, chakra disrupter seals, and durability seals. It had left him with a killer headache, and by the time he arrived Hinata was dead asleep. The second day he was running around placing all the durability and chakra disrupter seals into a matrix along the inside of the village wall which was equally time consuming.

The third day he was given a list by the Hokage of who to distribute the chakra storage seals to. So once again he was running around the village, knocking on doors and distributing seals. It wouldn't have been too big of a problem except that every other shinobi didn't want to accept things from him, especially his help. He thanked Kami that he had thought to write down instructions because it would have almost killed him to explain the seals to each individual over and over again.

But today it was the same process once more, he had to run around delivering the last few hundred seals and finally report to the Hokage that all the seals were complete and distributed. It was a very tiring week but at least he can say that he has done everything he could to protect his village.

As Naruto closed his eyes he wore a satisfied smile because he knew he'd done his best to make sure those Invaders would be defeated.

I know I brought up before that amounts of chakra could be measured accurately so below is what I think how much chakra different rank jutsu would cost.(if units of chakra existed)

Average E-Rank: 25 units

Maximum E-Rank: 50 units

Average D-Rank: 150 units

Maximum D-Rank: 250 units

Average C-Rank: 500units
