So, what kind of nature does Orochimaru's "resurrection" forbidden technique rely on for this primordial spell mark?

The answer to honesty is: solidification.

In the vision of Cheng Jizo, in the purple solution in front of him, the young man used the countless unique substances in his blood as the original "seeds", absorbing the natural energy floating in the solution and the external environment, those colorful natural energy, forming a unique "purple", those small, galaxy-like purple light grew and grew, covering the surface of the blood boy's body, which was the solid shell.

This kind of blood inheritance is similar to immortal arts, both of which absorb natural energy and form some kind of delicate balance structure, which [solidifies] the almost infinite amount of natural energy in the human body and uses it.

The wonderful thing is that this "curing" has good plasticity.

Makoto remembered several users of the "curse mark" cultivated by Orochimaru, the Otoshinobi quartet, and even Sasuke before opening the kaleidoscope writing wheel eye, their spell mark transformation was almost like a strong breeding armor or exoskeleton, using the curse mark as a seed, with the form that best suited its own fighting style, the spider form of Oni Tong Maru, the gigantic transformation of Jirobo, and Sasuke's wings, etc., which vary from person to person.

Orochimaru is really an amazing ninja, and if it weren't for Sasuke's accident, the ninja would definitely be able to bring great changes to the ninja world.

Primordial spell seals can take on different forms depending on the information they contain.

This [message] can be a cuticle, a kunai pattern, a spider form, a wing—or even, a "person".

A large snake pill.

Makoto gently rubbed his eyebrows, feeling a little dizzy for his sudden penetration of Orochimaru's entire forbidden system.

If a person deciphers and copies all of his "information", including his body's genetic sequences, life experiences, knowledge, etc., into this spell and sets it to be "expressed" under certain conditions, then as long as there are enough such spells and exists for a long enough time, can it be said that this person has achieved "eternal life"?

In the original work, all the users of the spell mark have a backup of the Great Snake Pill on their bodies.

Whether it's the red beans who have proven this, the dead Otoshinobi Four and Jun Maro, and even in some inconspicuous places in the ninja world, there are big snake pills everywhere.

Even, with such a convenient ability as spiritism, I believe that all these spell seals that contain the backup of the Great Snake Pill are likely to be linked in some way, and the latest information can be written at any time.

What a troublesome guy.

Although he understood the principle of Orochimaru's curse seal system and found the most suitable material such as the original curse seal blood inheritance, Makoto couldn't copy Orochimaru's genius-level ninjutsu.

Without him, testing one's own genetic sequence, under the technical conditions that Cheng currently masters, is already a long-time job, not to mention the more troublesome digitization of memory, spirit, and even soul.

The human body, the soul, and the study of this aspect are the unique strengths of Orochimaru.

However, perhaps the shadow clone, a perfect replication of itself, would help in this regard?

"Eternal life" is too fascinating realm, and Makoto put his finger against his forehead, deep in thought.

“…… Top dog? ”

After screaming a few times, seeing that Makoto did not react, the female ninja with black-rimmed glasses was helpless, and stepped forward and gently shook Makoto's body.

Cheng woke up in shock and put down his hand: "Qianzhi, what's the matter?" ”

Chichi repeated what he had just said: "The experiment has been successful, should we start preparing for the next stage?" ”

Try out a standard spell sigil exoskeleton?

Makoto nodded and said, "I understand, please start it, this project is under the sole responsibility of Chichi Kojima." ”

"Yes!" Everyone in the lab replied loudly.

Chichi Kojima had an expression of exhaustion and joy on his face, and he bowed to Makoto seriously.

To tell the truth, Chichi Kojima, including everyone in the laboratory at this time, is not the top part of the village, the kind of researcher who showed extraordinary talent early on, was either absorbed by the shadow department directly under the Hokage, or was recruited by various clans on favorable terms, and it was not the turn of the Ninja Reform Association, an organization that mainly aimed at the development of middle and lower ninjas.

However, these research ninjas who also have a solid foundation of basic knowledge are actually no worse than the geniuses of Orochimaru, Tsunade's Laboratory, or the Hinata Vault in some ways, and what they lack is only the kind of genius that is unique to them, and they have the talent to determine the direction of research and shine in key fields.

And this part, Makoto alone is enough to make up for it. He grasps the general direction of research and development of the association's laboratory, although it is still not as good as the kind of laboratory composed of geniuses in various fields, but it finally has the qualifications to be compared.

With the deepening of research, I believe that with the progress and achievements of the association in various fields, there will be no lack of charm to attract geniuses to join in the future, and it will gradually embark on the road of benign development.

Makoto thought silently, but Chichi Kojima didn't pay attention to this often silent leader, she raised her palm and slapped it twice, attracting the attention of everyone present.

"Okay guys, you've worked hard these days, but the real research and hard work are still to come, I hope you can be prepared."

The female ninja Chichi wore a pair of black-rimmed glasses, and her wide forehead showed her extraordinary intelligence, and although she tried to smile at this time, no one could see the exhaustion on her face.

If you count the days when Makoto taught her internal strength, she has not slept for thirteen days.

Not only Chichi Kojima, but at least half of the people in this laboratory have been taught by Makoto and have chosen the secret technique of internal force to overcome the damage caused by not sleeping. And the other half of the people, there are also many people who will start sleepless after two months in order not to affect the work process.

In Yicheng's experience, after two weeks of sleepless sleep, the pain of losing sleep will start to affect their normal work, and this discomfort will continue until two months later, when they will start to get used to it. Even if they are accustomed to the pain, they may not be able to reach even a tenth of the people who can continue to engage in ninjutsu research without sleep, which requires a great deal of precision and memory, but the vast majority of the members of the laboratory still choose to do so under the premise of honesty.

If you ask them why they are working so hard, maybe they will all answer, "It's for our common [cause]." ”

This kind of enthusiasm is the biggest reason why Makoto is confident that he can surpass the other laboratories in the village and even in the ninja world.
