Konoha The day the last piece of the reconstruction project was settled, the whole village was immersed in unprecedented joy.
It has only been half a year since the catastrophic invasion of Pain. The ruins that were once devastated and as far as the eye can see have completely disappeared. Smooth and wide hardened roads run through the whole village, and there are brand-new and neat houses on the roadside, and the courtyards of every household. New green plants have been planted in the house; the Hokage buildings, Konoha Hospital, and Ninja Academy in the core area have all risen from the ground. They are built according to the building-boundary integrated approach designed by Rinto. The project is completed, with a magnificent appearance, and the functions and protective properties inside are far better than before; brand new ninja training grounds and trial grounds are put into use one after another. Even Jonin level Ninjutsu training will no longer cause large-scale damage. Destruction; the underground pipe network, global sensing network, and village protection barrier system are all put into operation. The entire village's infrastructure and security protection level have far exceeded those before Pain's invasion, and are firmly at the top of Shinobi World's.
The Daming Mansion of Land of Fire sent a mission. Seeing the brand new Konoha, they were so shocked that they were speechless. Other villages of Five Great Shinobi Villages also sent messengers one after another, in the name of condolences, but in fact to investigate the situation - after all, Konoha half a year ago was also razed to the ground by Pain. Everyone thought that it would take at least ten years for Konoha to recover. Unexpectedly, in just half a year, Konoha not only completed the reconstruction, but even became stronger overall than before.
The whole Konoha, up to Hokage Tsunade, down to the ordinary villagers, they all know that behind this miracle, it all depends on the reclusive Mr. Rinto. From the solidification of the foundation, the strengthening of building materials, to the architectural design and infrastructure reconstruction, to the village protection barrier and the training ground system, every key node of Konoha's reconstruction was overcome by relying on the plan given by Rinto in an understatement, one after another seemingly unsolvable difficulties.
Many villagers spontaneously brought home-cooked food and handmade thank-you gifts to Rinto, but they were all stopped politely by the ninjas guarding the gate. Everyone knew that Mr. Rinto hated being disturbed. He took action to solve these problems, never for gratitude or reward, but just for his research.
In the brand new office in the Hokage building, Tsunade looked at the comprehensive reconstruction completion report on the table, breathed a long sigh of relief, leaned back on the chair, and showed a long-lost relaxed smile on his face.
"I can't believe it, it only took half a year to complete it all." Shizune brought a cup of hot tea, his tone full of emotion, "Before, I wouldn't have dared to think about it."
"It's all thanks to Mr. Rinto." Tsunade took the teacup and nodded, his tone full of joy and gratitude, "Without him, let alone half a year, five years, we may not be able to complete the reconstruction, let alone reach the level we are now. By the way, as mentioned before, are all the thanksgiving gifts and resources prepared for Mr. Rinto ready?"
"Ready." Shizune nodded quickly, "We have sorted out all the forbidden arts documents and secret arts records in Konoha's library, as well as Hokage's research notes from past dynasties. We have also prepared the highest-standard supply of research materials. No matter what rare materials or experimental equipment he needs, they can be supplied unconditionally. We have also prepared the fiefdoms and honorary titles specially sent by Daming Palace."
Tsunade stood up and said, "Let's go and send him there in person. Whether he needs it or not, this is what Konoha should have."
Half an hour later, Tsunade and Shizune once again stood in front of Rinto's hospital. In the past six months, they have rarely disturbed Rinto. They always came with clear technical problems and corresponding research data, and left after getting the plan without staying any longer. This was the first time, and they came simply to express their gratitude.
Tsunade raised his hand and knocked gently on the door of the courtyard, with a respectful tone. "Mr. Rinto, sorry to bother you, I am Tsunade, Konoha's reconstruction work has been completed. We came here specifically to tell you, and also brought you a little thank you gift."
The courtyard gate was quiet for a few seconds, and then Rinto's cold voice came, with obvious impatience. "I'm not interested in thanking you, and I don't want to hear these trivial things. If you have nothing else to do, just leave and don't disturb my experiment."
The reaction was exactly as expected. Tsunade smiled helplessly and said quickly, "Mr. Rinto, we brought all the forbidden arts documents in Konoha's library, Hokage's research notes from past dynasties, and Shinobi World records various secret techniques, I thought it might be able to provide some reference for your research. In addition, we have given you Konoha the highest level of material supply authority. If you need any experimental materials or equipment, you can provide it at any time, and we will send it to you as soon as possible."
There was silence for more than ten seconds, and then the courtyard door slid open with a click.
Rinto stood inside the door, his eyes immediately falling on the thick pile of documents held in Tsunade's hand, and the impatience in his eyes dissipated a bit. He was not interested in any fiefdoms, titles, or gifts of thanks, but these Shinobi World's forbidden arts documents and historical research notes may provide some new ideas and references for his research.
In the past six months, he has thoroughly studied all the research materials obtained from the Pain invasion incident. Rinnegan's Six Paths Power, Soul Anchoring Theory, microscopic reconstruction of inorganic matter, integration of buildings and barriers, distributed perception networks, all the rules and theories that can be extracted from these incidents have been thoroughly studied and archived by him.
His research has entered a bottleneck period. The existing samples and data can no longer support him to explore deeper - the ultimate origin of Chakra, the origin of Six Paths Power, the deeper secrets of the soul and the rules of life and death. For these things, in the existing data of Konoha, there are only sporadic legends and fragmented records, and there are no actual measured samples and data for research.
He has even begun to consider whether to leave Konoha and go to other places in Shinobi World to find new research materials. The forbidden arts documents and historical research notes brought by Tsunade may provide him with some new directions.
"Bring the information in, take away the other things, I don't need them." Rinto stepped aside, his tone still flat, without any hint of gratitude, only interested in the literature.
"Okay, okay." Tsunade responded quickly, walked into the yard with Shizune, and carefully placed the documents in his arms on the experimental table. "These documents are copies of the originals. You can use them as you like. If there are other needed documents and materials, please let us know at any time, and we will send them to you immediately."
Rinto had already casually picked up the top book of Second Hokage's research notes on forbidden arts. He glanced over it quickly and had no intention of listening to Tsunade's words. He just waved his hands and said as if to shoo away flies, "I understand, you can go, don't disturb me to read the information."
Tsunade and Shizune looked at each other, smiled helplessly, and without saying anything else, quietly exited the courtyard and closed the door. They had long been accustomed to Rinto's temperament, so being able to accept these materials was an unexpected gain.
In the yard, Rinto had already walked into the laboratory holding these documents.
He put these materials into categories, starting with Second Hokage Tobirama Senju's forbidden art notes. As Shinobi World's famous "forbidden art master", Tobirama developed Flying Thunder God, Impure World Reincarnation, Multiple Shadow Clone Jutsu and a series of far-reaching forbidden arts. His research notes contain a large number of research records on the development of Ninjutsu, Chakra rules, soul and space secrets.
Rinto's reading speed is extremely fast, and he quickly flips through the pages of notes. Most of the contents are not too new to him - he has already understood the spatial coordinate logic of Flying Thunder God through space folding technology; the Chakra allocation principle of Shadow Clone Jutsu is also within the coverage of his Chakra General Model.
It wasn't until he turned to the research records about Impure World Reincarnation that his eyes stopped.
In the notes, Tobirama recorded the original intention of developing this forbidden technique, the basic principles, and some data during the experiment. The core logic is: use living people as sacrifices, use the flesh and blood of the deceased as the medium, and remove the soul of the deceased from Pure Land is recalled and forcibly bound in the body of the sacrifice, creating a puppet that is immortal and can be infinitely regenerated, and can also retain all the Ninjutsu and Kekkei Genkai of the deceased.
Rinto's eyes suddenly showed a hint of interest.
He previously studied Rinne Rebirth and figured out the cross-dimensional rules for the soul to be recalled from Pure Land, and also mastered the anchoring technology of the soul and the body. But Rinne Rebirth is to recall the soul into the original, intact body and restart the life cycle, which is a positive application of the rules of life and death.
Impure World Reincarnation, however, is another extreme application - forcibly pulling the soul back from Pure Land and binding it in a completely unfamiliar sacrificial body. It can also achieve immortality, infinite regeneration, and even suppress the consciousness of the deceased, turning the soul into a puppet that can be controlled by others.
This involves the forced binding technology of the soul, the forced binding mechanism of the soul to a strange body, the underlying logic of immortal regeneration, and the principle of replicating the deceased's abilities during life. These are all areas that he has not systematically touched on in his previous research.
More importantly, this forbidden technique is equivalent to artificially creating a large number of different types of research samples - different Kekkei Genkai ninjas, developers of different secret techniques, and even legendary ninjas from past generations. Their Chakra characteristics, Kekkei Genkai rules, and the underlying logic of the secret technique are all precious research materials that he had difficulty accessing before.
There are not many records about Impure World Reincarnation in the notes. There are only basic development ideas and core technique frameworks. There are no detailed experimental data and complete technique details. Tobirama also marked it in the notes. This forbidden technique is too unethical and the risk is extremely high. It has been banned by him and will not be further studied.
Rinto put down his notes and tapped his fingertips on the table. He had no interest in the forbidden technique itself or in controlling the dead to fight. But the soul-binding rules, the undead regeneration mechanism behind this technique, and the large number of different types of ninja samples it could bring about were extremely attractive to him.
However, this forbidden technique has been banned for decades. After Tobirama, few people have mastered this technique, let alone applied it on a large scale. Even if he wanted to study it, he did not have the corresponding samples and measured data, so he could not develop this forbidden technique himself and conduct experiments on living people - he was not interested in this kind of meaningless killing, and he was too lazy to spend this effort.
He put the notes aside casually, noting the existence of this technique in his mind, but did not pay too much attention to it. After all, it was only of theoretical research value, without actual samples, and it was just talk on paper. He continued to look through the remaining literature, hoping to find other valuable research directions.
But Rinto did not expect that the forbidden technique he had just seen in his notes, which had been banned for decades, had been rediscovered and even optimized and improved to the extreme.
In the darkness of Shinobi World, a storm that can subvert the entire Shinobi World is already quietly brewing.
In addition to Konoha, the remaining forces of Akatsuki, under the leadership of Obito, are advancing Eye of the Moon Plan; and Kabuto Yakushi, who was once the right-hand man of Orochimaru, is already in Orochimaru Based on the research of, he developed Impure World Reincarnation Jutsu to the extreme. He traveled to every corner of Shinobi World and collected countless flesh and blood samples of legendary ninjas. An unprecedented Impure World Reincarnation army was gradually taking shape in his laboratory.
Abnormal incidents at the border have begun to appear sporadically. At the borders of Land of Fire, Land of Earth, and Land of Wind, several caravans and small patrol teams have disappeared inexplicably, leaving only There were strange battle traces, and no clues could be found about the murderer. Incidents of missing ninjas and stolen cemeteries also occurred in the other four major ninja villages. However, each ninja village was busy with its own affairs and regarded these as sporadic security incidents and did not pay enough attention.
Even Konoha received reports of abnormal situations from the border patrol, but they just regarded them as the work of wandering rebels and did not think about it further.
Rinto is still immersed in his own research, paying no attention to the undercurrents of Shinobi World outside. He has read through all the literature, and most of the content does not go beyond his existing theoretical system. There are only sporadic records of secret techniques that can supplement some marginal data for his research.
As days Tenten passed, Konoha's life was completely back on track. The ninjas resumed their daily tasks and training, the villagers lived and worked in peace and contentment, and the whole village was thriving.
Until this day, an urgent battle report came from the border of Land of Fire, which instantly broke Konoha's peace and sent an unprecedented research sample to Rinto.
