The departure of the first Hokage was actually expected by the first one.

He developed the technique of reincarnation in the soil, and of course he was well aware of its limitations.

There are two solutions to this technique, a fatal loophole, and a countermeasure.

There are two solutions, one is to unravel the spell by the practitioner himself, and the other is to be obsessed by the psychic person, and if he has no attachment to the yang world, he can become a Buddha and leave, and even the caster can no longer detain his soul.

There is only one fatal flaw in this technique, and that is ...... If the psychic person himself has learned the reincarnation of the Filthy Earth, and is aware of this loophole in the Reincarnation of the Filthy Earth, then he can take the initiative to cut off the reincarnation contract between the caster and the psychic person by using the seal of the Reincarnation of the Filthy Earth. Once this happens, the psychic will often choose to counterkill the caster.

And what is the countermeasure for the reincarnation of the filthy earth......

This is something that Kazuma has never said to anyone.

Just like what happened to the original Hokage, when the life energy that was the carrier of the living sacrifice was depleted, the filthy earth reincarnation naturally could no longer be maintained.

As a result, the only way to deal with the reincarnation of the Filthy Earth is to artificially increase the rate at which the life energy of the living sacrifice is consumed!

There are many methods, but the most efficient is undoubtedly to use the mass destruction ninjutsu to crush the reincarnated people of the filthy earth, causing them to consume a large amount of life energy of the living sacrifices again and again to restore their bodies.

When the number of times the Reincarnation of the Filthy Earth reaches the limit of the number of times they can be annihilated and restored, they will naturally be defeated.

However, this method is also very demanding for attackers.

According to the speculation of the Kazuma back then, even if the psychic was just a small lower ninja, it would take a single ninja at the level of the Thousand Hands Pillar to be able to grind the reincarnated person of the filthy earth to death before the chakra and physical strength were exhausted.

Therefore, Kazuma feels that this kind of response is equal to nothing for normal ninjas.

Back in the cave, Kazuma and Sasuke told the third and fourth generations of the first Hokage about the departure of the first Hokage.

The third generation sighed: "It's a pity that I couldn't let the first generation of adults leave with peace of mind...... This ninja world hasn't seen hope yet......"

Sasuke wiped the long sword he was carrying with him and said coldly, "Perhaps, hope didn't exist from the beginning. ”

"Have you given up?" said Kazuma, holding his arms together, "Indra." ”

"A thousand hands," Sasuke pointed diagonally at the side of the second Hokage as he carried his sword, "don't call me by that name." ”

The second generation squinted and moved his fingers.

"Sasuke!" Miyome scolded.

The long sword was lightly pulled in his hand, and the blade flashed in an arc in the air, and with a bang, Sasuke put the long sword into the scabbard behind his waist with his backhand.

The armsless four generations looked left and right, and finally sighed lightly, and looked at the innermost part of the cave, leaning against the rock wall, a mummy-like white chrysalis with a large seal written on it.

This is, Naruto's corpse.

It was sealed here by the first Hokage with the sealing technique of the Uzumaki clan.

The fourth generation muttered, "I still don't understand why Naruto couldn't be reincarnated by the filthy earth......"

The three generations were silent, Naruto Uzumaki was taken away from the Nine-Tails and died, unlike when he and the four generations were killed, and his soul was sealed in the mask of death.

It stands to reason that Naruto's soul has gone to the Pure Land, and it is impossible for him to have no attachment to this world and cannot summon it - that is, the late Naruto Uzumaki is fully qualified for reincarnation in the Filthy Land.

But when the second generation taught Sasuke to be reincarnated in the soil, no matter how many times the latter tried, he couldn't succeed in reincarnating the soil.

He furrowed his eyebrows, as the original founder of the Filthy Earth Reincarnation, he still wondered about this.

Instead of looking at Naruto's body, Sasuke walked towards the entrance of the cave, "It's time to go out, I want to replenish my food." ”

A few reincarnated Hokage don't need to eat, but Sasuke Uchiha is a big living person, and if he wants to ensure full physical strength and chakra, he has to eat on time.

But as soon as he took a step, a surge of heat surged in his left eye, and Sasuke sighed, and a chakra spirit flew out of his left eye, turning into a white-clothed and white-haired immortal, which was the big barrel of wooden feathers.

The Six Dao Immortals sat cross-legged at a low altitude and sighed, "I can't sense Naruto's soul in the Pure Land, he's like...... It doesn't exist in this world at all......"

With these words, the living and the dead present were silent, as if they were all dead.

"If that's the case...... That's not good news, Six Dao Immortals ......" the face of the third generation was slightly gloomy, "You also said before that if you want to seal the Otsuki Kaguya, you must have Naruto of Asura and Sasuke of Indra join forces to seal it...... But now, let alone the living Naruto, we can't even get the dead back......"

The Six Dao Immortals could only be silent.

"There's always a way! Kazuma looked resolute, "I, you, plus the Six Paths Immortals, even if Naruto's kid is completely wiped out, we will recreate him...... This ninja world needs him to live, so he doesn't want to die!" He looked at the silent four generations and arranged: "Four generations, you take Sasuke to find food, and I will go to the laboratory with Sarufei first." You guys take care of it, and bring Sasuke over as well. The experiment required the power of the asura sealed in Sasuke's left eye, as well as the guidance of the six immortals...... No problem, Ancestor of the Ninja Sect?"

He stared at the six immortals.

Yu Yi smiled bitterly: "If you can save the ninja world, it doesn't hurt to take the old decay to study." It's just that...... I sealed the power of the Asura in Sasuke's left eye to minimize its loss, but after all, there is no maintenance of Naruto, the reincarnation of the Asura, and the power of the Asura is to use a little less, you have to think clearly. ”

With a cold face, "It's better than doing nothing!"

The Six Immortals sighed, and turned into a spirit chakra and burrowed back into Sasuke's left eye.

The four generations walked silently to Sasuke's side, Sasuke stretched out a hand and pressed it on the shoulder of his broken arm, and as the four generations launched the Flying Thunder God Technique, the two disappeared into the cave.

"Let's go, Ape Fly. The second generation said to the third generation, "You kid seems to be called a doctor of ninjutsu, you should be a good assistant, right?"

Sandaime smiled bitterly, "Lord Kasama, I'll do my best......" He sighed lightly, "It's a pity that my apprentice has also fallen into the infinite moon reading, otherwise, you and him may be able to succeed in ......"

With one hand on the shoulder of Miyome, and the other hand on the top of the mummy that sealed Naruto's body, he activated the Flying Thunder God Jutsu and left the place and appeared in an underground laboratory.

In the past few years, the four Hokages took Sasuke to evade the pursuit of Otsuki Kaguya and Black and White Jue, and fled all the way, leaving two different flying thunder magic styles hidden along the way, and finally the five of them fled to the vast sea.

And this laboratory is the base of several Orochimaru that Sasuke took them to find, and the experimental equipment and materials that were scavenged were built in an underground cave built with earth retreat.

Similar underground laboratories, Kazuma and the others have been abandoned several times, all of which were forcibly transferred after being discovered by the Black Jedi.

Put the mummy aside.

The three generations looked at the cultivation tank that filled the room, and inside were one after another artificially cultivated Naruto Uzumaki clones, connected to various instruments and recording data.

As for the energy supply of the laboratory, it is a special sealing array that uses a timed input of thunder power.

"Don't look at it, monkey, come and help!" said with a cold face as he walked through the corridors between the cultivation tanks.

Like the cell research of the first Hokage, Naruto's cells, which possess vigorous vitality and autonomy, cannot be cultivated into a complete clone, nor can they give birth to a sound consciousness or personality in his brain. What was spawned and cultivated with the DNA in Naruto's corpse was nothing more than Naruto-like "corpses" one after another. If you forcibly clone a living thing, the final result will be the same as the research on the original Hokage cells back then - the cloned ones are not the original Hokage or Naruto Uzumaki, but one by one!

Miyome sighed and followed.

—————————

Shiyome took Sasuke and moved to what he remembered as a primeval forest.

Looking up at the rhizome of the huge sacred tree across the forest, with rows of white chrysalis hanging under it, the four generations sensed it for a moment, nodded to Sasuke and said, "It's all beasts, no humans." ”

Sasuke didn't speak, pulled out his long sword, and jumped into the root of the sacred tree in mid-air.

Head down on his feet, hanging upside down on the lower surface of the sacred tree, Sasuke runs with his sword.

These white pupae resemble silkworm cocoons, and their interiors are filled with humans and animals. The spirits of these beings fell into the infinite moon reading, and their bodies became the nourishment of the sacred tree, and finally turned into fruits to be picked by Kaguya.

The fourth generation is proficient in the art of flying thunder, and his perception ability is comparable to the immortal mode, Sasuke can accurately select those "silkworm cocoons" that are animals inside, swing his sword to cut off the connection between them and the sacred tree, and fall to the ground as his own rations.

After slashing four in a row, Sasuke immediately jumped off the ground.

The four generations had already put the four white chrysalis together, and as soon as Sasuke landed, he took Sasuke and the results and left immediately.

A few minutes after the two left, on the rhizomes of the sacred tree that Sasuke had plucked, two complete white bodies appeared.

"Ran away again...... said one of them.

"Escape quickly...... "Another Bai Jue said.

"Flying Thor is a trouble......

"But Kaguya is also studying time and space ninjutsu......"

"yes, it's always going to catch their ......"

The two Bai Jue chatted privately for a while, and then buried themselves inside the sacred tree again as if diving, and they didn't know where they swam to.
