The war of Pain invasion has lasted for a whole day.
From Six Paths entering the country, to Super Shinra Tensei razing Konoha, to Naruto rushing back to the village to fight to the death with Pain, and finally being defeated by Chibaku Tensei seal, the entire Konoha has been completely reduced to ruins. The number of surviving ninjas is less than 30% of the original number, the medical system has completely collapsed, and the temporary first aid shed is filled with critically injured people who are dying. Moans, cries, and desperate roars can be heard one after another in the ruins.
Six Paths of Pain still controls the absolute initiative. Deva Path is guarding Chibaku Tensei who has sealed Naruto. The remaining five are still searching in the ruins, clearing out the remaining resistance forces and demanding more information about Naruto. The whole village is shrouded in death. In the shadow of Konoha, the senior officials were hiding in a temporary underground bunker, facing a one-sided battle, helpless. Tsunade's Chakra was almost exhausted, and even maintaining Katsuyu's treatment was becoming more and more difficult. Looking at the rising death toll, their eyes were full of powerlessness and despair.
The entire Konoha is struggling in this catastrophe. Only this area in the northwest corner of the village is still as quiet as a corner forgotten by the world.
Rinto's laboratory was tightly wrapped by seven layers of nested space folding barriers. The artillery fire, screams, and explosions outside were completely isolated. From the first moment of Pain's invasion, to now when Konoha is on the verge of collapse, he has not stepped out of the laboratory during the entire process, and has not even opened the space barrier surrounding the laboratory once.
The village outside turned from prosperity to ruins, countless people died, countless families were broken, the life and death fight between Naruto and Pain, the major event that shocked the entire Shinobi World, he did not participate in, and he did not even take the initiative to pay attention.
The only thing he did was to rely on the sensing nodes he deployed in advance and spread throughout the village to completely and accurately collect all the actual combat data of all Rinnegan's abilities in this war.
At this time, Rinto was sitting on a chair next to the experimental bench, sorting out all the data collected during the day. On one side of the experimental bench, there were more than a dozen thick encrypted volumes stacked up. Each volume corresponded to a core competency of Rinnegan, which recorded complete measured data, disassembly of the underlying mechanism, mathematical model construction, formula derivation, and even his own optimization plan.
The bottom file is the full-dimensional data of Shinra Tensei's repulsive force field. From super-large-scale village-destroying releases to close-range tactical-level rebounds, he has dismantled all parameters, mechanisms, and flaws.
One level up is the analysis of the gravity rules of Banshō Ten'in, which is completely recorded in the book from the anchoring mechanism and traction model to the application boundaries in different scenarios.
Further up, there is Chibaku Tensei's research on gravity field and space distortion, which not only contains the complete dismantling of the technique, but also the formula for forming a space singularity derived by him based on actual measured data, and the logic for cracking the seal.
In addition, Chakra interference and signal transmission mechanism of Black Receiver, puppet body transformation logic of Six Paths of Pain, remote Chakra transmission model, vision sharing and multi-body synchronization system of Rinnegan, and even Including the Summoning Technique contract seal of Animal Path, the Chakra swallowing configuration of Preta Path, and the details of the soul extraction technique of Human Path, all the contents were clearly organized and filed by him.
This war that brought the entire Konoha to the brink of destruction was a tragic disaster and unforgettable pain for everyone at Konoha. But for Rinto, this was just a one-day, full-scenario, full-dimensional actual test of Rinnegan's capabilities. It provided him with a massive amount of extreme scene data that could not be simulated in the laboratory for free.
His previous research on Rinnegan only focused on a fragment of Black Receiver and a few scattered pieces of information from Jiraiya. His knowledge of Rinnegan was almost blank. But now, relying on this War, he has thoroughly understood Rinnegan's core capabilities, from the underlying rules to the application details. Even the underlying logic of many spells that Nagato himself did not fully understand, he used precise formulas and models to dismantle clearly.
Rinto locked the last volume on Naraka Path's life restoration and King of Hell's summoning mechanism. He looked at a cabinet full of research materials with eyes full of satisfaction. These data not only completed His understanding of the ultimate application of Yin-Yang Release allowed him to come into contact with the rules of gravity, space, and even the boundaries of the rules of soul and life, making the entire Chakra general theoretical system he built more complete and deeper.
He didn't even ask how many people died in this war, what Konoha became, whether Naruto lost or won, and what Pain would do next. The only thing he cared about was whether the sensing nodes had completely collected all the spell data, and whether any key mechanism details had been missed.
After sorting out all the archived information, Rinto picked up the Black Receiver sample placed on the sterile operating table and placed it again under the high-power microscope. With the complete Rinnegan With Chakra data, he had a deeper understanding of the transformation mechanism and signal transmission logic of Black Receiver. He adjusted the experimental parameters and started a new round of verification experiments, completely ignoring the moans and desperate cries of the wounded who were getting closer and closer outside.
Konoha outside has completely reached a desperate situation. Naruto has been sealed, the top combat forces have almost been wiped out, the medical system has completely collapsed, and a large number of seriously injured people cannot receive treatment and can only die little by little in pain. Tsunade Chakra was exhausted. Faced with the mountains of dying and wounded, he was at the end of his rope. He only had the last and only possible hope left in his mind.
The man who lived in the northwest corner of the village and stayed behind closed doors the entire time, but whose understanding of Chakra, life, and damage far surpassed that of the entire Shinobi World - Rinto.
In the laboratory, Rinto is still immersed in his own research. He is isolated from the earth-shaking outside world, life and death, and outside the space folding barrier. In his world, there are always only data, formulas, rules, and endless exploration of the origin of the world.
He still will not participate in anything about Konoha, will not care about the survival of the village, and will not care about those dying lives. Unless those things can bring new and valuable materials to his research.
