A certain scientific Naruto

The next evening.

"Teacher Kushina, I'm going to start engraving the seal." Yuyi said.

In a room on the second floor, except for Kushina, only Yugoromo and Minato are here, and Yuyi is now going to engrave the last part of his sealing barrier on Kushina's back.

"let's start."

Kushina said, now that he has accepted Hagoromo's statement, Kushina is no longer entangled. The sealing method is the last resort after preventing the tailed beast from escaping. Then her ending can be predicted.

"It's just a precautionary measure, that's not going to happen."

Minato said from the side, the expression on his face was still very kind, but it was impossible for him not to be worried in this situation.

"Then I'm going to do it."

Hagoromo nodded to Minato, and then began to describe the spell.

This is the name of the seal enchantment under Yuyi's arrangement.

And the key to activate the sealing barrier, Yuyi will be arranged on Kushina's body.

At the same time, it is not only the key to activate, but also the only safe means after the operation is activated. After all, this operation of Yuyi is not used to deal with tailed beasts.

The principle of the technique is very simple, and it is still an improvement on the four-image seal.

Whether it is the four-image seal or the inner four-image seal, they are actually seals constricting inwards. It is their function to restrict or even annihilate a certain space with great constricting force.

In comparison, this kind of constriction is like absorbing and locking something in a certain space with great gravitational force.

As for the spell engraved on Jiu Xinnai's body, the outermost part is the ordinary inner four-element seal, while the inner part is a different four-element seal.

After a very complicated transformation and experiment, Yuyi successfully reversed the four-element seal, turning that "gravity" into a "repulsion", which was used to offset part of the effect of the four-element seal and isolate Kushina out of danger.

If we talk about the seal style, the entire seal style has two parts, one part on Kushina's body, and a larger part in the external environment, but structurally speaking, this technique as a whole is composed of three parts.

To put it bluntly, this set is actually to create a safe space inside the four-element seal. The four-element seal will function normally outside the safe space, but the inside will not be affected.

Under various measures, it will ensure that there will be no problems with Kushina inside after the operation is activated.

When the sealing enchantment is activated, the outer wall of the four elephants will be opened at the outermost periphery, and Kushina will be in the isolated space inside the seal of the four elephants.

Safe isolated space.

There are four seals on the outside, and a safe space on the inside. As for the middle part, it is the functional part that can keep this enchantment going.

In the normal state of Lisixiang Seal, it only takes a moment from activation to completion, but this technique will last for more than 10 minutes.

Therefore, only a huge chakra like Kushina can support such a technique.

Moreover, compared with the general Lisixiang seal, the scale of this technique is also different.

Assuming that due to some kind of accident, Jiu Xinnai was accidentally taken away from this position, the scale of the enchantment space opened just based on the spells on her body is the same as that of a general four-element seal, but in this place, With the help of the huge technique arranged by Yuromo in advance and Kushina's chakra, the space can be extended to three kilometers in an instant.

And at a deeper level, if the nine-tailed chakra is extracted, the scale will explode to more than ten kilometers.

Once this technique is activated, everything in this range except Kushina will be wiped out into nothingness, so Yuyi said that it was made by the country.

This kind of super long maintenance time and the possible limit scale can be called a frightening effect, but it is actually just to deal with a spell:

Godly.

The approach and ideas are not exquisite, but simple and crude are equally effective.

Yuyi couldn't remember how long the virtualization ability of the right eye could last, but 10 minutes should be enough.

He continued his work with a focused expression, and in just a short while, the technique spread all over Kushina's entire back, and her skin was almost invisible.

However, at this time, Minato grabbed Yu Yi's hand, and his work had to be temporarily suspended.

Minato has enough reasons to stop Hagoromo, because the spell that Hagoromo drew behind Kushina's back is different from what he showed the two of them in advance.

The changes are only minor, but the water gate is still recognizable at a glance.

Among the spells that Yuyi showed the two in advance, this sealing barrier can only be activated by Kushina, and the timing or whether to activate it is completely up to her. But now, Kushina is not the only one who can activate the spell. There is a second person.

This second person is naturally Yu Yi himself.

If such a change is made, Yuromo can also activate the spell on Kushina when necessary, and the spell interacts with her gossip seal to forcibly extract the chakra of Nine Tails, and then block the entire space on the largest scale stand up.

At this moment, Minato understood that this technique was not designed to deal with Kyuubi after breaking out of the seal, no wonder there was a part that used Kyuubi's chakra.

This spell is used against unknown enemies who might take advantage of this opportunity and try to capture the Tailed Beast.

The reason why Yuyi arranged the operation behind Kushina was that the operation was really complicated, and the second was that he didn't want Kushina to see the changes in the operation.

This kind of change can be seen by Minato, and of course Kushina can also see it, so Yuyi will not let Kushina see it.

It's just that if Yu Yi forcibly activates such a technique, the complexity of the technique will definitely exhaust his chakra, so how can he escape from such a large-scale destruction?

Yuromo turned his head, still looking at Minato with that calm gaze, then he nodded again towards Minato.

"Has it been completed?" Kushina asked after noticing that Yuyi had stopped.

Minato, after all, let go of Yuromo's hand.

"Not yet, but soon."

Yuromo replied, his voice sounded the same.

"Then why did it stop?"

"This... I'm looking at the cherry blossoms. Teacher Kushina, if you look ahead, you can see the cherry blossoms."

"Oh, summer is coming, this is the last cherry blossom this year..."

"Wait, is it time to see the cherry blossoms?"

Jiu Xinnai felt that with such an unreliable disciple, she should catch a cold in a while.

Looking at it from this angle, the cherry blossoms under the setting sun have a strange and bright red blood color, but human blood can also dye it redder.

The blood could be the enemy's, or of course his own.

But after all, this is a last resort, and I hope it won't be used.

To be precise, Yuyi and Minato should have eliminated the enemy before using this method.
