Konoha's anxiety is spreading at a speed visible to the naked eye.
A month has passed since the first Impure World Reincarnation attack. The conflict on the border has intensified, and the dead summoned by Impure World Reincarnation are getting stronger and stronger. From the original ordinary Jonin, to Seven Ninja Swordsmen of the Mist, the former Kage of each ninja village, the legendary strongman of the Kekkei Genkai family, and even the fallen Hokage of Konoha, and Orochimaru, one of the legendary Sannin, all appeared in the attack list.
The battle reports from the front line were getting more and more tragic. Facing these immortal Impure World Reincarnation strongmen who also controlled the top Ninjutsu, the Konoha ninjas fought extremely hard. Conventional The attack is completely ineffective, and the only way to deal with it is to seal it. But facing the large-scale Impure World Reincarnation legion, the efficiency of Sealing Jutsu is extremely low, and it requires the cooperation of multiple ninjas. Casualties will occur if you are not careful.
In just one month, Konoha's ninja troops suffered a lot of casualties. Even many experienced Jonin fell into the hands of Impure World Reincarnation ninjas. What made Tsunade even more distressed was that it was not just Land of Fire. On the border of, the other four major ninja villages were also attacked by Impure World Reincarnation one after another, and the entire Shinobi World fell into an unprecedented panic. Everyone knew that a war sweeping the entire Shinobi World was imminent.
In Hokage's office, the atmosphere was so depressing that one could hardly breathe. The core senior executives of Tsunade, Shikaku, Shikamaru, Kakashi, Jiraiya, and Konoha were all gathered here, and everyone's expressions were extremely solemn.
"The pressure on the front line has reached its limit." Kakashi spoke first, his voice full of exhaustion, "Tsuchikage and Kirigakure, the predecessors of Iwagakure yesterday,'s Seven Ninja Swordsmen of the Mist appeared on the Western Front at the same time, and we lost an entire squadron. In the end, we had to sacrifice three Sealing Squad ninjas to barely seal two of them, and let the rest escape."
"Sealing Jutsu The gap is too big." Shikaku rubbed his swollen temples and frowned, "All Konoha ninjas who are proficient in Sealing Jutsu, totaling less than two hundred, have all been sent to the front line, but they are still not enough. Facing the endless stream of Impure World Reincarnation ninjas, seals can only cure the symptoms, not the root cause at all."
"What's even more troublesome is that we still haven't figured out who the caster behind it is and what its purpose is." Jiraiya said solemnly, "To be able to collect so many flesh and blood samples of legendary ninjas and optimize Impure World Reincarnation to this extent is definitely not something that ordinary rebel ninjas can do. I suspect that this matter has something to do with the remnants of Akatsuki and Orochimaru."
Everyone was silent. All they could do was to respond passively, but facing such an enemy that could not be beaten or killed, the passive defense would only be worn down little by little. In everyone's mind, they all thought of the same person - Mr. Rinto.
Half a month ago, Rinto made it clear that he had figured out the core mechanism of Impure World Reincarnation and had a way to crack it. But in the past half month, they only dared to send a steady stream of samples sent from the front line, and did not dare to ask about the progress of the cracking plan, for fear of making Rinto impatient and completely abandon it.
"We can't wait any longer." Tsunade gritted his teeth and broke the silence, "If we continue like this, our ninja army will be exhausted sooner or later. Mr. Rinto, we have to ask."
"But, we all know Mr. Rinto's temperament." Shizune said hesitantly, "He only cares about his own research. If we push him too hastily, will it offend him?"
"Just urging is useless, we have to provide him with something of sufficient value." Shikamaru suddenly spoke with determination in his tone, "What we gave Mr. Rinto before were just scattered records about Impure World Reincarnation in the copied Second forbidden art notes. And Konoha's confidential archives also contain Second's original forbidden technique research notes, which contain Impure World Reincarnation's complete process from project establishment, development, to final ban, all experimental data, the underlying logic of the technique design, and the defects and risks of the technique he discovered, all are recorded in it."
He paused and continued, "Although Mr. Rinto has figured out the mechanism of the improved version of Impure World Reincarnation, the original development notes can help him thoroughly understand the underlying design logic of this technique, and even find flaws in the improved version that the user may not be aware of. These first-hand development data are definitely of high value to his research."
As soon as these words came out, everyone's eyes lit up, but then they showed hesitation.
The original forbidden technique notes of Second Hokage Tobirama Senju are one of the core secrets of Konoha. They contain not only the complete development records of Impure World Reincarnation, but also the development process, core principles, and experimental data of a series of forbidden techniques such as Flying Thunder God Technique, Mutually Multiplying Explosive Tags, Spirit Transformation Technique, and Bringer-of-Darkness Technique. They are the most precious inheritance of the Konoha, Senju Clan, and Hokage systems.
The risk of handing over such core secrets to an outsider is too high. Even if Rinto has always only cared about research and has no interest in Konoha's power or Shinobi World's disputes, once these forbidden techniques are leaked, the consequences will be disastrous.
"I know everyone's concerns." Shikamaru looked at everyone's expressions and continued, "But in the current situation, we have no other choice. No matter how precious the note is, it is still dead. Guarding it will not solve the current Impure World Reincarnation crisis. Konoha can't keep it, so what's the point of these secrets?"
"Furthermore, we have all seen what kind of person Mr. Rinto is for more than half a year. He has no interest in rule, war, or power. He only cares about the rules behind the techniques and the value of research. These notes are just sealed files in our hands, but in his hands, they can exert their greatest value, help us find a way to crack Impure World Reincarnation, and may even help us deal with greater crises in the future."
Shikamaru's words spoke to everyone's heart. Now Shinobi World is undercurrent, and an unprecedented war is coming. It is meaningless to guard these confidential files. Only by getting the method to crack Impure World Reincarnation can Konoha survive this crisis.
"I agree with Shikamaru." Jiraiya was the first to nod, "Lord Tobirama developed these forbidden techniques with the original intention of protecting Konoha. Now Konoha is facing a life and death crisis. Use these notes to find a way to crack Impure World Reincarnation. Lord Tobirama has a spirit in heaven and will understand."
"I also agree." Shikaku nodded, "Now there is no better way than this. Moreover, we do not give him the notes, we exchange them with him. We give him the original research notes, and he gives us a complete and scalable Impure World Reincarnation cracking plan. This is a win-win situation."
Tsunade was silent for a few seconds, and finally slammed the table and made up his mind. "Okay! That's it. I'll go to the confidential archives in person and get Second's original forbidden technique notes. Shikamaru, come with me to see Mr. Rinto."
Half an hour later, Tsunade and Shikamaru stood outside the gate of Rinto's courtyard. In Tsunade's hand, he held a wooden box sealed with multiple layers of Sealing Jutsu. What was inside was the most complete original forbidden technique research notes preserved by Tobirama Senju.
This is the most core secret of Konoha. Even Tsunade is taking these notes out of the confidential archives in the Hokage building for the first time. She felt both uneasy and with a trace of I am looking forward to it, and I am worried about whether there will be any problems if I hand over such an important thing. What I am looking forward to is that with these notes, Rinto can come up with a complete cracking plan as soon as possible to solve Konoha's urgent need.
Tsunade took a deep breath, raised his hand and knocked gently on the courtyard door, his tone was extremely respectful. "Mr. Rinto, sorry to bother you, we have something very important and want to communicate with you."
The courtyard gate was quiet for a few seconds, and Rinto's cold, impatient voice came. "If it's a trivial matter on the front line, there's no need to talk about it. Just leave the new sample and leave."
"Mr. Rinto, we are not here to ask for the cracking plan." Tsunade spoke quickly, explaining the purpose of our visit very quickly, "We brought Second Hokage Tobirama Senju's original forbidden technique research notes, which contain the forbidden technique Impure World Reincarnation, from the beginning The complete experimental records sent to the ban, the underlying design logic of the technique, all defects and risk records, as well as all the research data of Lord Tobirama on the soul rules and forbidden technique development. We would like to give these notes to you for research reference, and hope to help you improve your research on Impure World Reincarnation."
She paused and added, "We have only one request. I hope that after you complete the research, you can give us a set of Impure World Reincarnation cracking solutions that can be promoted and used by frontline ninjas to help our brothers on the frontline deal with this crisis."
After saying that, the two held their breath and waited nervously for the response. They knew very well that these original notes were the most valuable chips they could offer, but they were not sure whether Rinto would be interested or whether they would accept this exchange.
After more than ten seconds of silence, the courtyard door slid open with a click.
Rinto stood inside the door, his eyes immediately falling on the wooden box in Tsunade's hand. The impatience in his eyes instantly dissipated, replaced by unabashed interest.
What he had seen before was only sporadic fragments about Impure World Reincarnation in the reprint given by Konoha. He could only see the basic framework of the technique, but could not see Tobirama's complete ideas for developing this technique, the problems encountered during the experiment, and the details of the exploration of the soul rules.
The development notes of the original version are extremely valuable to him. On the one hand, they can help him understand the underlying logic of Impure World Reincarnation more deeply, compare the differences between the original version and the improved version, and find the root weakness of this technique; on the other hand, Tobirama, as Shinobi World is the top developer of forbidden arts. His research on other forbidden arts, such as Spirit Transformation Technique, a secret technique that directly affects the soul, and Flying Thunder God, a Space-Time Ninjutsu underlying design, can provide him with a lot of references and new ideas for his research.
"Bring the things in." Rinto stepped aside, with a hint of imperceptible urgency in his tone, his eyes never leaving the wooden box.
"Okay, okay." Tsunade and Shikamaru's hearts suddenly fell to the ground. They quickly walked into the yard and carefully placed the wooden box containing the notes on the experimental table.
Tsunade raised his hand and unlocked the multi-layer seal on the wooden box, revealing a dozen yellowed notebooks inside, all written in Tobirama Senju's handwriting. They were filled with dense formulas, surgical design, experimental records, and thoughts and corrections during the development process.
"Mr. Rinto, these are all the original forbidden technique notes of Lord Tobirama. We have never leaked the contents to the outside world. They are the core secrets of Konoha." Tsunade said softly, "You can study all the contents at will. We only have one request, that is, we hope that you can give us a practical cracking plan for Impure World Reincarnation."
Rinto had casually picked up the top notebook, which was the core record about the development of Impure World Reincarnation. His eyes quickly scanned the page, and Tobirama's rigorous experimental records, ideas for surgical design, and exploration of the binding of soul and body were presented to him bit by bit.
As he expected, the core logic of Tobirama's original technique is consistent with the current improved version, but there are many differences in details. The development process of Tobirama recorded a large number of experimental failure cases, such as the rejection of the soul and the body of the sacrifice, the failure of consciousness suppression, and the limitation of regeneration ability. These failed experimental data can just help him verify his theoretical model and complete the details that were not covered before.
"I left the notes." Rinto didn't even raise his head. He looked through the notes and said calmly, "Impure World Reincarnation, I have figured out the core mechanism and cracking logic. If you want a scalable cracking plan, come and get it in three days."
Three days?!
Tsunade and Shikamaru were stunned, their eyes full of surprise. They originally thought that it would take at least a week or even longer for Rinto to study these notes, but they didn't expect that he actually said that he would be able to come up with a complete plan in three days. This means that the ninjas on the front line will soon be able to get rid of the dilemma of being able to only passively seal, and have a way to truly crack Impure World Reincarnation.
"Thank you so much, Mr. Rinto!" Tsunade said excitedly, "If you have any needs, please tell us at any time and we will fully cooperate!"
Rinto didn't respond. All his attention was completely immersed in Tobirama's notes, and he didn't even wave his hand to chase people away. Tsunade and Shikamaru looked at each other, and both of them slowed down their steps wisely, exited the courtyard quietly, and closed the courtyard door cautiously, for fear of disturbing him.
After walking far away, the two of them breathed a sigh of relief.
"Great! Finally there is hope!" Tsunade's face showed a rare relaxed smile for a while, "With Mr. Rinto's cracking plan, we no longer have to be afraid of those immortal Impure World Reincarnation ninjas."
"I knew that these notes must be attractive to him." Shikamaru also smiled, "For us, it is a life-saving secret, and for him, it is precious information for perfect research. Next, we only need to wait for three days, and then organize all the ninjas to learn the cracking plan."
In the yard, Rinto had already walked into the laboratory holding all the notes.
He classified more than a dozen notebooks according to the research direction. He first picked up the core development notes of Impure World Reincarnation and carefully read them word for word. The development ideas of Tobirama were extremely rigorous. From the initial establishment of the spell project, to the exploration of the principles of soul recall, to the selection of sacrifices, the design of consciousness suppression spells, and the construction of the regeneration mechanism, every step had detailed experimental data and thinking records.
The more Rinto looked at it, the more interested he became. Tobirama's development logic for Ninjutsu was fundamentally different from his - Tobirama went through a lot of experiments, trial and error, optimization, and perfection of the techniques, and finally formed usable forbidden techniques; while he first dismantled the underlying rules, and then designed the corresponding application plan based on the rules.
But decades ago, Tobirama was able to rely on repeated experiments to understand the basic logic of soul recall and forced binding, and developed Impure World Reincarnation, a forbidden technique that touches the rules of life and death. Even if there are many flaws, it is enough to show that his understanding of Ninjutsu is far superior to that of ninjas of the same generation.
Through the original notes, Rinto also completely understood where the current improved version Impure World Reincarnation has been optimized.
The original technique of Tobirama has extremely high requirements for sacrifices. It requires sacrifices with blood and physique similar to that of the deceased in order to better reproduce the abilities of the deceased. Moreover, its binding power on the soul is limited, and it is easily suppressed by the powerful ninja's consciousness of breaking free. The regeneration ability also has an obvious upper limit, making it impossible to achieve unlimited perfect regeneration.
The current improved version has completely solved these defects. The corpses of ordinary ninjas can be used as sacrifices, and the peak strength of the deceased can be perfectly reproduced. The spell's suppression of consciousness is so strong that even the strongest Kage Level can hardly break free, and it also achieves unlimited regeneration in the true sense.
More importantly, the improved version of the technique has a design that splits the soul into each cell, which is completely absent from the original version. In the original Tobirama technique, the soul is still completely anchored in the core node of the body. Once the core is destroyed, the technique will become ineffective, which is also one of the core flaws of the original technique. The improved version completely solves this problem. Even if the body is blown into powder, as long as one cell remains, regeneration can be completed.
"It seems that the person who improved this technique not only understood the original design of Tobirama, but also had a deep understanding of the soul rules and Yin-Yang Release, and even incorporated Cursed Seal's related technologies." Rinto muttered in a low voice, and wrote the core differences between the improved version and the original version on the slate with his fingertips.
In the original notes, most of the flaws in the spell recorded by Tobirama were solved in the improved version, but new and more core life gates were also left. For example, the improved version implanted the spell fragments into every cell. Although it achieved soul binding of the whole cell, it also made the spell's coverage extremely wide. As long as a targeted spell erasure configuration that can spread to cells throughout the body can be designed, the entire spell can be completely released at once.
After reading the related notes of Impure World Reincarnation, Rinto picked up other forbidden arts notes. Flying Thunder God Technique's spatial coordinate positioning logic, Spirit Transformation Technique's soul separation and control rules, Mutually Multiplying Explosive Tags's Chakra detonation mechanism, Bringer-of-Darkness Technique's environmental interference principle, and these forbidden techniques developed by Tobirama each correspond to different rule fields, adding a large amount of measured data and design ideas to his research system.
Especially Spirit Transformation Technique, this secret technique that allows the soul to separate from the body, travel freely, and even directly attack the enemy's soul, can just supplement his soul rules research system, allowing him to have a more comprehensive understanding of the nature of the soul, the separation and binding of the soul and the body.
For two days and two nights, Rinto barely rested and studied all the dozen or so original notebooks of Tobirama. Not only did he thoroughly understand Impure World Reincarnation's full-link logic from development to improvement, but he also obtained a large number of new research ideas from other forbidden arts research, and improved his own space rules, soul rules, and Chakra control system.
More importantly, by combining the original design ideas of Tobirama and the improved spell mechanism he had previously dismantled, he not only improved the previously designed cracking plan, but also found a cracking method that was more efficient, more suitable for frontline ninjas, and could even be applied in batches. He even deduced several countermeasures against Impure World Reincarnation.
He put down his last notebook, picked up a charcoal pen, and began to write on the slate a Impure World Reincarnation cracking plan for frontline ninjas that could be standardized and promoted. He designed two plans with different difficulties: one is a high-precision spell erasure configuration suitable for medical ninjas and sensory ninjas, which can accurately release soul restraints., allowing the soul of the dead to return Pure Land; the other is a simpler and easier-to-use sealing type, which can quickly block the Chakra cycle and spell activation of the Impure World Reincarnation body. Even an ordinary Chunin can be used after simple training.
At the same time, he also wrote down the core weaknesses and coping skills of Impure World Reincarnation based on his own research, so that frontline ninjas can develop corresponding tactics for different Impure World Reincarnation ninjas.
On the morning of the third day, Tsunade and Shikamaru were waiting outside the courtyard gate early, feeling both expectant and nervous.
As soon as the appointed time arrived, the courtyard door opened on time. Rinto threw out a seal scroll and a stack of bound manuals, and said in a calm tone, "The cracking plan is here, divided into two difficulty levels of operation specifications, as well as coping skills and weakness analysis. Let the ninjas practice in a safe environment first, confirm that the operation is OK, and then promote it to the front line."
Tsunade quickly stepped forward, caught the scroll and manual with both hands, and held them tightly in his arms, his voice trembling with excitement. "Thank you so much, Mr. Rinto! You really helped Konoha a lot!"
"If there are new, special Impure World Reincarnation samples in the future, continue to send them to me." Rinto said lightly, and before they could say anything else, he turned around, closed the door, and walked back to the laboratory.
Tsunade and Shikamaru didn't care to say anything more, and immediately rushed back to the Hokage building with the scroll and manual in hand. They couldn't wait to promote this cracking plan to the entire army and solve the urgent need on the front line.
In the laboratory, Rinto's attention was no longer on the cracking plan. Tobirama's notes helped him improve the underlying logic of Impure World Reincarnation, and what he was really interested in was the more Impure World Reincarnation samples that would inevitably appear next.
Each of those powerful men of the past who possess Kekkei Genkai, Kekkei Tōta, and special secret techniques is a unique research sample that can help him thoroughly understand the underlying rules of Chakra Nature Transformation and Kekkei Genkai, and improve his Chakra general theoretical system to an unprecedented level.
He can already foresee that with the outbreak of the Shinobi World war, a steady stream of precious samples will be delivered to him. And his research will also enter a new stage through this war sweeping Shinobi World.
