The next evening.

"Teacher Kushina, I'm going to start engraving seals." Hashii said.

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

"Let's get started."

Kushina said that since she had accepted the statement from Yuyi, Kushina was no longer confused. The sealing style was the last method to prevent the tailed beast from escaping. In fact, when Kushina thought, if the magic style really needed to be activated, her ending could be foreseen.

"This is just a means of prevention, that kind of thing won't happen."

Minato said from the side, the expression on his face was still very gentle, but he could not be worried under such circumstances.

"Then I'm going to do it."

Yuyi nodded at Minato and began to use the art of hand to portray the art.

The inter-multiple compound four-syllable seal is the name of this seal barrier arranged by the feather.

As for the key to the seal barrier, the Holy Yi will be arranged on Kushina.

It is both the key to the activation and the only safe means after the technique is activated. After all, Yuyi's technique is not used to deal with the tailed beast.

The principle of the technique is very simple, and it is still only an improvement to the Four Symbol Seal.

Whether it is the Four Symbol Seal or the Four Symbol Seal, they are actually inward-retracting seals, and the limit or even destroy a certain space with a great binding force is their function.

To compare, this kind of convergence is like absorbing something with great gravity and locking it in a certain space.

The art engraved on Kushina's body is the most outermost part of the ordinary inner four-syllable seal, while the inside is a different four-syllable seal.

After a very complicated transformation and experiment, Yuyi successfully reversed the Four Symbol Seal, turning the "gravity" into "repulsive force", which was used to offset part of the effect of the Four Symbol Seal and isolate Kushina from danger.

If you talk about the seal style, the entire seal style has two parts, Kushina is part of it, and the external environment is a larger part, but from a structural point of view, this technique is composed of three parts.

To put it bluntly, this set is actually just to create a safe space inside the inner Four Symbol Seal. The four Symbol Seal will work normally in the outer part of the safe space, but the inside will not be affected.

Under various measures, it will ensure that Kushina inside will not have any problems after the operation is activated.

When the seal barrier is activated, the outer wall of the inner four symbols will be opened at the outermost periphery, while Kushina will be in an isolated space inside the inner four symbols seal.

Safe isolated space.

There are four-syllable seals on the outside and safe space inside. As for the middle part, it is the functional part that can keep this barrier maintained.

The four-syllable seal in the general state only lasts a moment from activation to end, but this technique will last for more than ten minutes.

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

Moreover, compared with the ordinary Sixiang Seal, this technique has a different scale.

Assuming that Kushina was accidentally taken away from this position due to some accident, the scale of the open barrier space based on her body's stance is the same as that of the ordinary Four Symbol Seal. However, in this place, the space can be extended to three kilometers in an instant by the huge stance arranged by Hashii and Kushina's chakra.

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

Once this technique is activated, everything except Kushina will be destroyed into nothingness within such a range, so Yuyi said that this is the refining of the country.

This super long maintenance time and the possible extreme scale are terrifying effects, but in fact they are just to deal with a technique:

Divine power.

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

Yuyi couldn't tell how long the blurred power of the right eye could last, but ten minutes should be enough.

He continued his work with a focused expression. In just a moment, the techniques spread throughout Kushina's back, and her skin was almost impossible to see.

However, at this time, Minato grabbed Yuyi's hand, forcing his work to temporarily pause.

Minato had enough reasons to stop Hoi, because the technique that Hoi painted behind Kushina was different from what he showed to the two of them in advance.

The change was only very small, but Mizuno could see it at a glance.

Among the techniques that Hayi showed them to the two of them in advance, this seal barrier can only be activated by Kushina, and the timing or whether it is activated is entirely controlled by her. But now, not only Kushina can start the technique, but also a second person.

This second person is naturally Yuyi himself.

If such changes are made, if necessary, Hoyi can also activate Kushina's styling, and the styling interacts with her gossip seal, forcibly extracting the nine-tailed chakra, and then blocking the entire space on the largest scale.

At this moment, Minato had already understood that this technique was not intended to deal with the Nine-Tails who rushed out of the seal. No wonder there was a part that used the Nine-Tails Chakra.

This technique is used to deal with unknown enemies who may take advantage of this opportunity to try to seize the tailed beast.

The reason why Yuyi placed the technique behind Kushina was that the technique was indeed very complicated, and the other was that he didn't want Kushina to see the changes in this technique.

This change can be seen by Minato, and of course Kushina can also be seen, so Hoshii won't let Kushina see it.

However, if Yuyi forcibly activates such a technique, his chakra will definitely be exhausted with the complexity of the technique. So how can he escape from the destruction of this scale?

Yuyi turned her head and still looked at Minato with that calm look, then he nodded at Minato again.

"Is it done?" Kushina asked after he noticed that Hayi had stopped.

Minato finally let go of Yuyi's hand.

"Not yet, but it's almost there."

Yuyi replied, his voice sounded nothing changed.

"Why did you stop?"

"This... I'm watching the cherry blossoms. Teacher Kushina, you can see the cherry blossoms."

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

"Wait, is it time to watch cherry blossoms now?"

Kushina felt that with such an unreliable disciple, she should catch a cold later.

From this perspective, the cherry blossoms under the sunset have a strange and bright red blood color, but human blood can dye it even more red.

These blood can be the enemy's, and of course it can also be his own.

But after all, this is still the last resort, and I hope I won't use it.
