After subdividing the process of the ritual into four stages, Hinata frowned slightly.

Beryuhu had only completed the first stage, and Danzou had fallen in the second stage, in other words, let alone completed, no one in the ninja world had ever tried to enter the third stage, let alone the fourth stage after the third stage.

According to the basic law of strength level improvement, the difficulty of the first stage of fusing the 'Blood Inheritance Limit' and the second stage of chakra quality improvement cannot be compared with the third stage of condensing the 'Dao Seeking Jade' and the fourth stage of chakra that completely integrates the five elements and seven attributes of yin and yang.

Because the difficulty of each stage increases exponentially, the further you go, the more difficult it becomes!

Relying on the two guinea pigs, Beryuhu and Tuanzang, Hyuga Mirror has found out the situation of the first and second phases, and all his current preparations are only for the first and second phases.

But the really crucial third stage, and even the fourth stage, was still a chaos for him, and he couldn't judge whether his preparation could cope with the third and fourth stages.

Come to think of it, there are only two ways to solve this problem.

Either raise another guinea pig as before, or try it yourself.

Cultivating a guinea pig again, whether in terms of time or efficiency, is unrealistic, after all, there is no such thing in the ninja world as Tuan Zang who dares to think and do, and is ambitious and talented, and has a lot of money.

What's more, it is difficult for ordinary mice to complete the first stage and the second stage in front of them, and step into the third stage to let the Hyuga mirror see what is going on.

So there is actually only one choice left for the Hyuga mirror, and that is to try it for yourself, maybe only if you really die once, you can know what is wrong.

"This may be the real reason why I ignored Shion's 'death prophecy' and insisted on performing the ritual!"

Hinata smiled self-deprecatingly.

Now he is stuck in a loop, that is, if he doesn't perform the ritual, he will never know what is wrong, but if he does the ritual, he will inevitably die in the ritual.

Fortunately, he has always been cautious, and he has already prepared the back hand of overturning the car in the ceremony, so in the face of this endless loop, he is not completely unable to crack it.

Hinata has always done a good job of managing his emotions, so he quickly calmed down the frustration in his heart, and from his previous anxiety about the uncertain outcome of the ritual, he turned to how to use a death to find out the third and fourth stages of the ritual, and clear all obstacles for the second ritual after resurrection.

At the same time, he must deal with the aftermath of his death and not allow the situation to collapse during this time.

After thinking about it for a long time, he suddenly had an idea, and it was Orochimaru, who had been defeated by Sasuke before, who gave him this inspiration.

"If the ritual is bound to lead to death, and there is no immediate resurrection, then 'Reincarnation of the Dirt' may be a good way to at least allow me to move freely and prepare for the second ritual."

In fact, there is a huge risk of getting out of control in the technique of 'reincarnation of the soil'.

And Hyuga Mirror took a fancy to this risk, because in the original time and space, Madara Uchiha easily got rid of Yakushidou's control by virtue of his own control of the 'Filthy Earth Reincarnation', and became a special 'Filthy Earth Body' that he mastered himself.

If death is inevitable, and Kaori is currently unable to perform the 'Reincarnation Innate Technique' in the near future, then making himself a 'Free Dirt Body' like Madara Uchiha is a good choice.

At this thought, the Hyuga mirror disappeared into the room in a flash.

Speeding through the village, he arrived at the Hokage Building in a blink of an eye, and then he walked to the classified archive located under the Hokage Building with a blank face.

In the dark passageway, he walked slowly.

"Hokage-sama!"

Every time he walked, a shadow hidden in the shadows would appear and salute him, and the shadows that he had to find a way to get around many years ago were now his loyal guards.

Hinata nodded casually to the dark parts, and passed all the levels all the way unimpeded, entering the confidential archives.

In the classified archive, he quickly found the box containing the 'Book of Seals', and after unlocking the sealing technique on the box, he took out the 'Book of Seals' inside.

Needless to say, this large volume of the 'Book of Seals' stored in the box was the one that Naruto had stolen from the original plane.

It can also be seen from this that with the strength of the village's guarding of the 'Book of Seals', Naruto, who did not even graduate from ninja school in the original time and space, and was not even considered a shinobi, would never succeed in stealing it.

There was no accident in that incident, only intentional!

Spreading out the 'Book of Seals' on the table, Hinata's gaze swept over the forbidden techniques recorded on it, and finally fell on the four big characters of 'Filthy Earth Reincarnation'.

Frankly speaking, Hyuga Mirror has little interest in the art of 'reincarnation in the soil'.

Of course, this is not because he looks down on this technique, but because his 'Blood Inheritance Snaring Project' takes up too much of his energy, so that he doesn't have the heart to dabble in techniques that have nothing to do with the 'Blood Inheritance Snaring Project'.

And now that the 'Filthy Earth Reincarnation' has also become part of his 'Blood Inheritance Snares Project', he must seriously study this technique.

After carefully studying the part of the 'Book of Seals' about 'Filthy Earth Reincarnation', Hinata had to admit that the second Hokage was a bold genius.

This method of summoning the undead through spiritism is really strange and ingenious.

"I can't imagine that this kind of forbidden technique that violates ethics was developed by the Hokage, it seems that among all the Hokage, my moral bottom line is still quite high!"

After sighing with emotion, Hinata Mirror earnestly studied 'Filthy Earth Reincarnation'.

To put it simply, 'reincarnation in the dirty earth' is to extract a small group of the deceased's spirit body through the cell organization of the deceased, and then use this small group of spirit body as a guide to channel the soul of the deceased in the underworld to the ninja world through spiritism, and then forcibly put the soul of the soul into a sacrifice prepared in advance.

Because of this, the strength of the sacrifice will directly affect the strength of the 'filthy soil'.

In the Fourth Ninja World War, Orochimaru used a special white doppelganger as a sacrifice to the first generation of 'Filthy Earth Reincarnation', and its strength was close to the strength of the first generation when it was alive, far better than the original 'Filthy Earth Body' during the middle ninja exam.

Rubbing her chin, Hinata asked, "It seems that I have to prepare a body for my 'filthy earth body'!" ”
