Naruto: Modern Science in Naruto

---

The blue lightning seemed to come alive, dancing in Haori's palm. His fingers seemed unable to contain this mass of chakra. Danger and destruction seemed to be imminent.

Kakashi and the others instinctively stepped back, subconsciously trying to get as far away from the lightning as possible. Their subconscious minds instantly told them how dangerous it was.

To think Haori was pretending to be the original creator while using someone else's jutsu in front of the real creator. He wasn't embarrassed at all.

"Its power is comparable to an S-rank jutsu!" Unlike Kakashi's retreat, Minato's eyes lit up. The power of the jutsu was certainly strong enough, but that wasn't the most attractive thing about it to Minato.

He saw something else. It was a seal-less jutsu. It changed the nature of chakra without hand seals and was able to form an enormous amount of chakra. The difficulty involved was obvious. This was what most attracted him.

"Truly amazing, Kushina. I didn't expect that your student would be able to develop a seal-less jutsu with this kind of power…"

Minato said with a sigh of admiration. He was currently inspired by the Tailed Beast Ball and developing the Rasengan seal-less jutsu, but he was still in the exploratory phase. The Rasengan only had a simple prototype, let alone adding chakra nature changes.

Seal-less jutsu doesn't need hand seals, so it can be activated instantly in battle, which has an incomparable advantage over jutsu that require tens of hand seals.

"Of course. Facts have proven that I am a very skilled teacher. I'm great at guiding students to develop their potential." Kushina said brazenly.

Haori was thinking, if he said that he had already completed this jutsu before meeting Kushina, what would the consequences be?

He thought about it for a while and decided to agree with Kushina's statement, because he had no interest in seeing what would happen if he told the truth.

However, Minato's understanding of the jutsu was now biased. Haori quickly explained, "Senior Minato, you're wrong. This jutsu can't really be considered seal-less."

"Really? But you didn't use any hand seals just now?" Minato was full of confusion at Haori's statement. Had Haori been using hand seals? Impossible. If he really had been using hand seals, there was no way he could have missed it.

Why then did Haori say that this wasn't a seal-less jutsu?

"Actually, Chidori can't really be considered a seal-less jutsu. It's just that my body is a bit special. I'm naturally very adaptable to Lightning Release. That's why I can perform it without hand seals," Haori dispelled the Chidori in his hand. Then he continued, "Chidori does need hand seals."

He started forming hand seals again.

Ugly – Hare – Monkey

After three hand seals, a ball of lightning appeared in Haori's palm once more.

Okay, he was actually doing this for Kakashi. Haori was a conscientious plagiarist. Even though he didn't have the right to sign his name, he wasn't going to take away Kakashi's right to use it.

(ShixT9: Atleast he's a little guilty, good enough I guess )

He believed that Kakashi, the original developer of the Lightning Cutter, would be able to use this jutsu soon after getting the hand seal sequence.

"I see. So it's just because of your talent?" After learning that Chidori couldn't be considered a seal-less jutsu, Minato's interest in the technique immediately waned.

After a brief exchange, Minato had to admit that Haori was indeed a genius ninja. Regardless of the Chidori jutsu, being able to use Lightning Release so proficiently at such a young age was definitely no small feat.

But this was not the same as the seal-less jutsu he was seeking.

At this point, Haori could already use Lightning Release and Fire Release. These two chakra natures were innate to him. Of course, compared to Fire Release, he was better at and preferred Lightning Release. Lightning Release and Fire Release each have their own merits. Lightning Release has a stronger single-target destructive power, while Fire Release has a larger area of destruction. Of course, this wasn't why Haori didn't like Fire Release. He didn't like Fire Release because he couldn't get A-rank Fire Release jutsu.

That's right. Kushina didn't know any A-rank Fire Release jutsu either. It was said that Konoha didn't have any A-rank Fire Release jutsu.

It was such a sad story.

In addition to these two innate chakra nature changes, Haori was also learning other nature transformations with Kushina, but there were no results yet.

Regardless of how others felt, Haori enjoyed this meal. For the next few days, he didn't see Kushina much. It wasn't until Minato left that she began to devote herself to seal technique development with renewed vigor.

Then, over the next week, she solved several difficult problems in succession, and the forbidden jutsu was finally completed.

…

One week later, on a clear morning, in the northwest corner of Konoha, on the edge of the barrier, in an area rarely visited, a dense forest.

One big and one small, one man and one woman, were acting stealthily in the early morning light.

That's right, these two people were Kushina and Haori.

Kushina carried a large scroll and walked to a certain distance from Konoha's protective barrier, then stopped there.

She couldn't go any further. Otherwise, the barrier would react, which might attract ANBU ninjas, and that could lead to their forbidden jutsu experiment being impossible to continue.

"Haori, come here. Put this scroll on the edge of the barrier. For special reasons, I can't get too close to the barrier," Kushina said to Haori.

Haori nodded, took the scroll, which was taller than he was, and walked step by step towards the edge of the barrier.

He could generally understand why Kushina couldn't get close to Konoha's barrier. Because she had once tried to sneak to the front lines, but luckily, she was caught by the Hokage. After that, the barrier added a special reaction device to the Nine-Tails chakra. As long as Kushina, the jinchūriki, got close to the barrier, the Hokage would know immediately.

So, for Kushina, Konoha was both a protective barrier and a cage.

Haori carefully placed the scroll on the very edge of the barrier, then unrolled it on the ground as Kushina instructed.

The scroll's interior was filled with densely packed characters. Characters formed lines, lines formed patterns.

The shape of the pattern itself was much more complex than the Four-Symbols Sealing Technique. It was also different from the Inner Four-Symbols Sealing Technique that was originally created in the Naruto world.

After unrolling the scroll, Haori quickly ran back to Kushina.

He wasn't cowardly. He just simply wanted to stay away from this dangerous thing.

"Report, platoon leader. Our Italian cannon is in place. Ready to detonate!" He reported to Kushina.

Kushina didn't actually understand what Haori was saying, but, miraculously, she seemed to understand the meaning.

She nodded. She was completely different from her usual self. Her expression was solemn.

"Anyway, let's back up a bit first, then back up some more. The range of this technique is still unknown. We have to ensure our safety."
