The shadowless lamp in the laboratory was on all night, and the cold white light filled the entire sterile operating room.
In the past half month, Rinto's sample storage cabinet has been filled with Impure World Reincarnation samples from the front line. From the very beginning, Sunagakure Magnet Release ninja, to Iwagakure's Explosion Release user, from Konoha's former patriarch of the secret family, to Kekkei Tōta who was just sent and mastered Dust Release's predecessor Tsuchikage fragments, the samples cover Impure World Reincarnation individuals from different ninja villages, different Kekkei Genkai, and different strength levels, forming a complete set of gradient sample libraries.
On the experimental platform, more than a dozen high-precision detection instruments are running at the same time. Different types of Impure World Reincarnation cell samples are placed in independent isolation detection cabins. Microstructure images, cell activity curves, Chakra spectrum data, and soul fluctuation trajectories are densely refreshed on the light screen. All information is recorded, archived, and comparatively analyzed in real time.
Rinto is sitting in the center of the experimental table, holding a micron-level Chakra engraving knife at his fingertips. On the light screen in front of him is a diagram of the microstructure of Reanimated Body cells magnified tens of thousands of times. He has been studying these samples for three days and three nights, and there is no trace of fatigue in his eyes, only extreme concentration and desire to explore.
In the previous chapter, he had already passed preliminary testing and figured out the overall Taijutsu framework of Impure World Reincarnation, but what he wanted was never the surface answer of "what", but the underlying rules of "why" - why the Impure World Reincarnation body can achieve infinite regeneration? Why can the body of the sacrifice perfectly replicate the Kekkei Genkai of the deceased? Why can the soul fragments split to the cell level maintain a stable state of binding? The answers to these questions are hidden in the microstructure of the Impure World Reincarnation cells, and in the underlying logic of the immortal repair mechanism.
The first thing he did was to build a complete comparison system to compare the structure of Impure World Reincarnation cells with three different types of cells: healthy human body cells, Yang Release-enhanced regenerative cells, and Six Paths of Pain puppet-modified corpse cells. The three sets of comparison data were placed on the light screen, and the special features of Impure World Reincarnation cells were clearly highlighted in an instant.
"Sure enough, from the cellular level, it is no longer a normal human tissue." Rinto muttered in a low voice, his fingertips crossed over the light screen, juxtaposed the structures of the three groups of cells, and quickly wrote the core conclusion on the slate with charcoal pen.
Conventional human body cells have clear cell walls, nuclei, and cytoplasm. The activity of the cells depends on the human body's life cycle and energy supply. The number of divisions and regeneration capabilities have clear physiological limits; even the regenerative cells activated by Tsunade Strength of a Hundred Technique only forcibly increase the cell division and regeneration speed through Yang Release Chakra. Essentially, they still follow the basic rules of human cells.
The cells of Impure World Reincarnation completely broke these rules.
The microscopic image on the light screen shows that although the basic framework of the Impure World Reincarnation cell retains the biological form of the sacrificed somatic cell, the internal structure has been completely transformed. The cell wall has been solidified by Chakra, forming an extremely stable structure. Conventional physical and Ninjutsu attacks are difficult to cause irreversible damage to the cell itself.; The cytoplasm is no longer filled with conventional organelles, but is filled with solidified Chakra networks. Each cell is like a miniature Chakra receiver and converter, which can directly receive the Chakra transmitted remotely by the operator, and can also directly convert Chakra into substances needed for body regeneration.
The core change is in the cell nucleus.
The nucleus of a normal cell stores an individual's genetic sequence, which determines the differentiation, growth, and regeneration of the cell. In the nucleus of the Impure World Reincarnation cell, in addition to the genetic sequence of the sacrifice itself, two sets of core imprints are forcibly implanted: one is the complete soul imprint template of the deceased, and the other is the control spell fragment of the caster.
This is the core design of the entire Impure World Reincarnation technique, and the source of all weird characteristics.
Rinto clearly captured the soul imprint in the cell nucleus through high-precision soul perception. The caster used an extremely rough but extremely delicate method to split the complete soul of the deceased into countless identical miniature imprints, which were anchored in the nucleus of each cell. Even if the entire body was blown to pieces, as long as there is one cell left, the soul imprint template inside is a complete "design drawing" that can replicate the entire body.
This also perfectly explains why Impure World Reincarnation's body can complete complete regeneration even if there is only an arm or a piece of meat left - because the core of regeneration is never the division and proliferation of cells, but the reconstruction of the entire body using the soul imprint as a template.
What interests him even more is that this set of soul imprint templates not only contains the soul origin of the deceased, but also completely reproduces all the physiological characteristics of the deceased, Chakra attributes, Kekkei Genkai gene sequence, and even The neural structure corresponding to Ninjutsu muscle memory. This is why the body of the sacrifice can perfectly reproduce the appearance, Kekkei Genkai, Ninjutsu abilities of the deceased, and even the characteristics of Chakra are exactly the same as the deceased's before death.
The caster is equivalent to using the soul imprint to directly rewrite the underlying genes of the sacrifice cells, transforming a completely unfamiliar body into a "replica container" of the deceased. This kind of forced rewriting of genes and cell structure has gone beyond the scope of Shinobi World regular Medical Ninjutsu and touches on the core rules of Yin-Yang Release creation.
The other set of spell fragments of the caster is like a lock, firmly locking the soul mark in the cell nucleus. On the one hand, it suppresses the soul consciousness of the deceased, making the deceased unable to control the body and can only become the puppet of the caster; on the other hand, it maintains the forced binding of the soul mark and the cell, preventing It stops the soul from breaking free from the shackles and returning to Pure Land; at the same time, it is also the Chakra receiving antenna, which can receive the Chakra transmitted remotely by the caster, providing regeneration and Ninjutsu release of the entire body.
Rinto even found subtle differences in the structure of the spells in different samples. The stronger the deceased and the tougher the soul, the more complex the structure of the spells implanted by the caster, and the stronger the suppression force. For example, the previous generation Tsuchikage In the fragments of, the complexity of the spell is far beyond that of the ordinary Jonin sample. It is obvious that the caster made targeted enhancements in order to suppress the consciousness of the strong Kage Level.
"It's interesting. It's much more sophisticated than the original design of Tobirama." Rinto picked up Second Hokage's forbidden art notes and compared them with the design ideas of the original Impure World Reincarnation recorded in the notes, with a hint of interest in his eyes.
Tobirama's notes clearly stated the flaws of the original Impure World Reincarnation: high-quality sacrifices are needed to barely replicate part of the deceased's strength. The binding power on the soul is limited and can easily be suppressed by a powerful ninja's consciousness. The regeneration ability also has obvious limitations. But now these samples in his hand, even if ordinary ninjas are used as sacrifices, can perfectly replicate the peak strength of the deceased. The soul binding is extremely strong, and the regeneration ability is almost indestructible.
Obviously, the person who mastered this technique has made a lot of subversive optimizations and improvements based on Tobirama, transforming this forbidden technique that originally had many flaws into a terrifying tool that can mass-produce undead legions.
After figuring out the microstructure of Impure World Reincarnation's cells, Rinto immediately turned the core of his research to the most bizarre part of the entire technique, and the most helpless part for Shinobi World - the complete mechanism of immortal repair.
The ninjas of Konoha only know that Impure World Reincarnation's body cannot be killed or blown to pieces, and can recover instantly even if there is only a little residue left. However, no one can explain exactly how this regeneration process occurs, let alone find a way to crack it. What Rinto has to do is to completely open this black box and dismantle every link, every triggering condition, and every underlying logic of regeneration.
He specially designed a controllable damage experimental system. In the isolation cabin, he applied different types and degrees of damage to different Impure World Reincarnation samples. He used ultra-high-speed detection equipment to record the entire process from the occurrence of damage to the completion of regeneration, with an accuracy of microseconds.
The first set of experiments was conventional physical damage. He used the Chakra blade to accurately cut off the muscle tissue of the sample and started high-speed photography at the same time.
On the light screen, the entire process of regeneration is clearly shown:
The moment the damage occurs, the spell fragments in the cells in the damaged area are immediately activated, and at the same time send damage signals to the surrounding cells; then, the Chakra network of the entire body is activated instantly, and a large number of Chakra converges towards the damaged area; then, based on the Chakra in the surrounding cells, The soul mark was used as a template, and the Chakra that was gathered was transformed through Yin-Yang Release to reconstruct the damaged muscle tissue, blood vessels, and nerves directly from scratch. The whole process took less than 0.1 seconds. The regenerated tissue perfectly matched the original structure without any trace of repair.
The second set of experiments involved extensive blast damage. He used Explosive Tag to blow up a Impure World Reincarnation body fragment into powder. Most of the cells were destroyed by high temperature and shock waves, leaving only a handful of intact cells.
The regeneration process allowed Rinto to further verify his judgment.
After the explosion, the soul imprints and spells in the few intact cells were instantly activated. With these cells as the core, Chakra quickly gathered to reconstruct the basic cell structure. Then, using the soul imprint as a template, it differentiated and reconstructed complete tissues and bodies step by step. Even if there were only a few cells left, it could be restored to complete body fragments in just a few seconds.
More importantly, he discovered in the experiment that there is almost no upper consumption limit for this regeneration process. He repeatedly blasted, burned, and corroded the same sample dozens of times with acid. After each time it was completely destroyed, the sample was perfectly regenerated, and the speed and completeness of regeneration did not decrease at all.
This is fundamentally different from all the regeneration techniques of Shinobi World.
Rinto On the stone tablet, Impure World Reincarnation clearly wrote the core differences between Impure World Reincarnation regeneration and conventional regeneration:
1. The regeneration logic is completely different: regular Yang Release Medical Ninjutsu, Strength of a Hundred Technique, Orochimaru's Style Substitution Technique, the core logic is "cell division and proliferation", which is based on existing living cells to accelerate division, differentiation, and repair damaged tissues. The essence is "continuation of life", which will inevitably consume life energy and the number of cell divisions. It is obvious that The exact upper limit. The core logic of Impure World Reincarnation's regeneration is "Yin-Yang Release creation based on the soul template", which uses Chakra to directly reconstruct matter. It does not need to rely on the division of the original cells. Even if there is only one cell left, the entire body can be recreated. The essence is "reconstruction of matter", and theoretically there is no upper limit.
2. The energy sources are completely different: conventional regeneration consumes the Chakra and life energy stored by the caster, so use a little less. However, the energy source of Impure World Reincarnation's regeneration is the caster's remote Chakra supply, as well as the Chakra transformation system anchored by the soul mark, as long as the caster's supply of Chakra continues and the soul mark is not destroyed, regeneration will not stop.
3. The repair accuracy is completely different: Conventional regeneration is difficult to perfectly repair nerves and the special organs corresponding to Kekkei Genkai, and it is easy to leave sequelae. The regeneration of Impure World Reincarnation is based on the complete soul mark as a template, which can achieve 100% accurate reproduction. Even the special cell structure corresponding to Kekkei Genkai can be perfectly reconstructed without affecting the use of Ninjutsu.
Through dozens of sets of controlled experiments, Rinto has completely dismantled the complete closed loop of the immortal repair mechanism, breaking the entire process into four irreversible steps:
1. Damage perception and signal activation: The moment the body is damaged, the spell fragments in the cells will immediately sense the damage, activate the global Chakra network, and synchronize the damage location and extent information.
2. Soul template retrieval: With the complete soul imprint in the surviving cells as the core, the complete structural information of the dead body is retrieved to determine the accurate template for reconstruction.
3. Material transformation of Chakra: Gather Chakra, and through the underlying rules of Yin-Yang Release, transform the invisible Chakra into tangible cells, tissues, and organs, which are completely reconstructed according to the soul template.
4. Structural anchoring and functional recovery: The reconstructed tissue is perfectly integrated with the original body, the Chakra network and soul binding are re-established, and complete physiological functions and combat capabilities are restored.
The core of the entire closed loop are two irreplaceable anchor points: the soul imprint template in the cell nucleus, and the control spell implanted by the caster.
The soul mark is the "blueprint" of regeneration, which determines what the reconstructed body will look like; the control spell is the "switch" and "energy pipeline" of regeneration, responsible for triggering regeneration, supplying Chakra, and maintaining the binding of the soul.
These two anchor points are not only the core of Impure World Reincarnation's ability to achieve immortality, but also the most deadly life gate of this technique.
Rinto has already found the core node of soul release in his previous preliminary research, and now, through in-depth dismantling of the cell structure and regeneration mechanism, he has a more accurate and comprehensive understanding of the weaknesses of this technique.
If you want to completely end the immortality of Impure World Reincarnation, there are three levels of cracking paths:
- The most superficial one is to seal the body. Use the powerful Sealing Jutsu to seal the entire body of Impure World Reincarnation to prevent it from moving and regenerating. This is the only way Konoha can do now. It treats the symptoms but not the root cause. It is only a temporary restriction and no real solution.
- The middle layer is the erasure control spell. Use precise spells to erase the caster's spell in the cells, cut off the caster's Chakra supply and soul binding, and either revive the consciousness of the deceased and control the body, or let the soul lose its restraints and automatically return to Pure Land. This is the method to crack a single Impure World Reincarnation individual from the root.
- The most fundamental reason is to terminate the spell of Impure World Reincarnation. As long as the caster removes the entire Impure World Reincarnation Jutsu, all the spells will be invalid, and all the summoned souls will lose their restraints and return to Pure Land, eliminating all Impure World Reincarnation individuals once and for all.
For these three levels of cracking methods, Rinto already has clear technical implementation paths. Especially for the spell erasure plan for a single individual, based on his own Soul Anchoring Theory, he has designed the corresponding precise intervention configuration, which can accurately erase the control mark of the caster and remove the forced binding of the soul without damaging the soul of the deceased.
But he still didn't tell Konoha these methods.
On the one hand, the samples sent by the front line were not comprehensive enough. He only got a few samples of Kekkei Genkai, Shinobi World, and a large number of rare Kekkei Genkai, secret techniques, and even Kekkei Tōta. He had not yet obtained the corresponding research data. On the other hand, he improved this Impure World Reincarnation The caster of has a little interest - he can optimize Tobirama's forbidden technique to this extent. This person's understanding of Yin-Yang Release, soul rules, and Cursed Seal technology far exceeds Shinobi World's normal level, and may also bring more unexpected research materials.
Rinto put down the carving knife in his hand, sorted and archived all the test data, cell structure analysis, and regeneration mechanism disassembly conclusions, and locked them in an encrypted file cabinet. This complete set of analysis reports completely stripped away all the disguises of the forbidden immortality technique that Shinobi World talked about, and turned it into a set of technique models with clear logic and clear weaknesses.
As soon as he filed the information, the sound of ninja's hurried footsteps came from outside the courtyard door, and a respectful report came from across the courtyard door, "Mr. Rinto! A new sample has been sent from the front line! It's Seven Ninja Swordsmen of the Mist from the previous generation of Kirigakure, and Ino-Shika-Cho family patriarch from the previous generation of Konoha, we have sent it to you!"
There was a hint of interest in Rinto's eyes. Ino-Shika-Cho's family secrets and Seven Ninja Swordsmen of the Mist's special abilities are brand new research samples.
"Bring it in." He said calmly, his eyes returning to the experimental table.
For Konoha, more and more legendary ninjas are being killed by Impure World Reincarnation, which means that the pressure on the front line is increasing and the crisis is getting worse; but for Rinto, this means that more and more unique research samples are being continuously sent to him.
He has no interest in the direction of the Shinobi World war or the survival of Konoha. What he cares about has always been the Chakra rules, the underlying logic of Kekkei Genkai, and the design principles of the secret hidden behind these samples. These are things that can make his research system more complete and closer to the origin of the world.
