A certain scientific Naruto.

The blue thunder light seemed to be alive in Yu Yi's palm, and Yu Yi's fingers seemed unable to suppress the ball of chakra, danger and destruction seemed to appear at any time.

Kakashi and the others unconsciously leaned back, instinctively trying their best to stay away from the thunder light. Very simply, their subconscious minds would tell themselves the danger of this thing.

It is said that Yuyi is pretending to be the original creator and performing other people's ninjutsu in front of the real creator, but he is not ashamed at all.

"A ninjutsu that is as powerful as an S-rank!" Unlike Kakashi's retreat, Namakaze Minato's eyes brightened. This ninjutsu is powerful enough, but this is not the most attractive place for Minato. He saw What, this is Muji Ninjutsu. It can change the nature of Chakra without making seals, and can form a huge amount of Chakra. The difficulty of it can be imagined, and this is what attracts him the most.

"It's really amazing, Kushina, I didn't expect your disciple to be able to develop such a powerful Muji ninjutsu..." Minato said with a sigh. At this time, he was inspired by Tailed Beast Jade and was developing Muji. Ninjutsu spiral pill, but he is still in the groping stage, spiral pill is only a rudimentary answer, not to mention the addition of chakra changes in spiral pill.

Muji ninjutsu does not require seals, so it can be cast instantly in battle, which has an incomparable advantage over ninjutsu that requires dozens of seals.

"Of course, it turns out that I am a teacher who is very good at teaching students and guiding them to realize their potential." Kushina said brazenly.

Yuyi was thinking at this time, if he said that he had completed this technique before meeting Kushina, he didn't know what the consequences would be.

After thinking about it for a while, he decided to agree with Kushina's statement, because he had no interest in seeing the consequences of telling the truth.

However, at this time Minato's cognition of this jutsu appeared to be biased, and Yuromo hurriedly explained, "Senior Minato, you are wrong, this ninjutsu cannot be regarded as Muji ninjutsu."

"Really? But you really didn't get a seal just now?" Minato was full of doubts about Yu Yi's statement. Could it be that Yu Yi just got a seal?Impossible, if he really got married, it would be impossible to hide it from his own eyes.

Then why did Yuyi say that this is not Muji ninjutsu?

"In fact, Chidori really can't be counted as Muji ninjutsu. It's just that my body is quite special, and I was born with a high adaptability to Thunder Dungeon, so I was able to do Muji." Yuyi scattered the Chidori in his hands. Bird, and then went on to say: "Chidori needs seals."

As he spoke, he began to make mudras with his hands again.

Ugly---Mao---Shen

After three seals, a cloud of thunder appeared again in Yuyi's palm.

Well, he actually did this for Kakashi on the side. Yuromo is still a conscientious pirate. Although he doesn't have the right of authorship, he will even deprive Kakashi of the right to use it if he doesn't hit anyone.

I believe that Kakashi, as the original developer of Rachel, should be able to use this ninjutsu soon after he gets the seal order.

"So it's just because of talent?" After learning that Chidori is not Muji jutsu, Minato's interest in this jutsu suddenly decreased a lot.

After a short exchange, Minato also had to admit that Yuromo is indeed a genius ninja. Regardless of Chidori's ninjutsu, being able to use Thunder Dun so proficiently at such a young age is absolutely extraordinary.

But this is not the same thing as the MUJI he pursued.

At this time, Yuyi was actually able to use Thunder Dun and Fire Dun, these two chakra attributes he was born with, of course, compared to Fire Dun, he was better at and liked Thunder Dun.Thunder Dun and Fire Dun have their own advantages and disadvantages, the single-body damage of Thunder Dun is stronger, and the damage area of ​​Fire Dun is larger...Of course, this is not the reason why Yuyi doesn't want to see Huo Dun, the reason why he doesn't want to see Huo Dun is - he can't get A Super fire escape ninjutsu.

That's right, Kushina doesn't know A-level fire escape ninjutsu. It is said that even Konoha doesn't have A-level fire escape ninjutsu.

It's a really sad story.

In addition to the changes in the Chakra nature of these two talents, Yuyi is still following Kushina to learn other changes in nature, but it will not be effective for a while.

No matter how other people feel, Yuromo had a good time eating this meal. In the next few days, he didn't see Kushina very much. It was not until Minato left that she began to devote herself to the seal with full energy technology development work.

Then within a week after that, she conquered several difficult problems one after another, and then this forbidden technique was declared completed.

………………

One morning a week later, at the edge of the enchantment in the northwest corner of Konoha, there was a dense forest with few people.

After a while, a man and a woman began to sneak around here when the sky was slightly bright.

That's right, these two people are Kushina and Yuyi.

At this time, Kushina carried a huge sealing scroll, walked to a certain distance from Konoha's protective barrier, and then stopped here.

There is no way, she can't go any further, otherwise the enchantment will react, which may attract Anbu ninjas, which may further prevent their forbidden technique experiments from proceeding.

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

Yuyi nodded, then took the seal scroll that was taller than him, and walked towards the edge of the barrier step by step.

He could roughly understand why Kushina couldn't get close to Konoha's enchantment, because before, she wanted to sneak to the front line, but luckily she was caught by Hokage, and since then, Konoha's enchantment has disappeared A special reaction device for Nine-Tails Chakra has been added. As long as Kushina, who is Jinchuriki, is close to the barrier, Hokage will know it immediately.

Therefore, for Kushina, Konoha is not only a barrier to protect her, but also a cage to imprison her.

Yuromo carefully placed the scroll on the edge of the barrier, and then unfolded it on the ground according to Kushina's instructions.

The inside of the scroll is filled with densely packed characters, the characters are combined into lines, and the lines are combined into spells.

The shape revealed by this technique itself is much more complicated than the four-image sealing technique, and it is also different from the original four-image sealing technique that was born in the Naruto world.

After unrolling the scroll, Yuromo quickly ran back to Kushina's side.

It's not that he's timid, he just wants to stay away from this dangerous thing.

"Report to the second platoon leader, our Italian artillery has been erected and is ready to detonate at any time!" He reported to Jiu Xinnai.

Kushina actually didn't understand that Yuyi said a ghost, but what was amazing was that she actually understood what it meant.

She nodded. At this time, she was completely different from her usual appearance. In short, her expression was very serious.

"In short, let's step back first, and then step back. The scope of this technique is still unclear. We have to ensure our own safety."
