The joy of new life brought by Rinne Rebirth lasted only a few days, before the heavy reality of post-war reconstruction overwhelmed the entire Konoha.
The people who were surviving the disaster walked out of the temporary shelter and faced endless rubble and ruins. More than 90% of the buildings in Konoha were completely razed in Super Shinra Tensei. Streets, residential buildings, schools, hospitals, and office buildings have all turned into layers of rubble, broken beams, and twisted steel bars. Even the originally clear terrain has been changed by the shock wave. The ground has been cut off by several meters, and there are pits and cracks left by the shock wave everywhere.
The first thing to start was the debris clearing work. The surviving ninjas, villagers, and even Genin, who had just graduated from school, all went into battle. Relying on Earth Release Ninjutsu and simple tools, they cleared the rubble bit by bit, searched for survivors still buried under the rubble, and collected the bodies of the victims. It took a full ten days to clear the ruins of the main road, but facing the reconstruction of the entire village, this was just the first step in a long march of thousands of miles.
The real desperate situation was completely exposed to everyone after the surface ruins were cleared.
In the temporary command tent in the Hokage building, the atmosphere was as depressing as if it were filled with lead. Tsunade was sitting in the main seat, with Konoha spread out in front of him The geological survey report jointly submitted by Civil Engineering Team and Rock and Earth Ninja, his brows were twisted into a knot. The tent was full of people, Shikaku, Shikamaru, Kakashi, and Konoha's most senior Earth Release Jonin, the patriarch of the civil engineering and construction family that has been passed down for generations, has powerlessness and anxiety written all over his face.
"The situation is worse than the worst outcome we expected." Earth Release, who is in charge of the global geological survey Jonin spoke in a hoarse voice, pointing the baton in his hand on the spread out Konoha global geological map, "Shinra Tensei's shock wave not only flattened the buildings on the ground, but its impact was transmitted down the ground, affecting the soil layer twenty meters underground. The entire underground structure of the village was completely destroyed."
He pointed to the areas marked with different colors on the map, and his tone became more and more serious. "In the central area of the village, where the Hokage Building and the commercial street were previously located, the soil structure within fifteen meters underground was completely shattered, the sand and soil were seriously liquefied, and the originally dense soil became It has become loose gravel and does not even have basic bearing capacity; in the surrounding residential areas, the soil layer has extensive cracks and looseness, and there are more than a dozen deep slip faults. Even if we build a house on it, there will definitely be subsequent settlement and collapse, and even a heavy rain can trigger a landslide."
The patriarch of the construction family next to him added, his tone full of despair. "In conventional reconstruction, the first step is to lay the foundation, but now the underground soil in the entire village is loose, and conventional foundation treatment methods are useless. We tried to use Earth Release to harden the top soil, but there is still loose soil under the hardened layer, which is disconnected from top to bottom, and cannot bear the weight of the building at all, let alone possible subsequent attacks and natural disasters."
"What about deep solidification? Can't we use Earth Release Ninjutsu to harden the deep soil layer as well?" Shizune couldn't help but ask.
"No." Jonin, who was in charge of the survey, immediately shook his head, "Conventional Earth Release hardening can only be achieved within a few meters of the surface. Going further down, the conduction efficiency of Chakra will drop sharply, making it impossible to control accurately. Moreover, it can be hardened by force., will cause more cracks in the soil, making the soil harder and looser, which will intensify the risk of settlement. Even if we ignore the cost and let all the Earth Release ninjas take turns to solidify bit by bit, it will take at least three years to complete the foundation treatment of the entire village, and we simply cannot afford to wait."
The rainy season is coming soon, and now everyone is crowded into temporary simple shacks, which cannot withstand the erosion of the heavy rain. Not to mention, Konoha, as the core of Land of Fire, has been in this semi-paralyzed state for a long time, which is a fatal blow to the hearts of the people in the country and the deterrence of other ninja villages.
But if the problem of the foundation is not solved, all reconstructions will be castles in the air. You cannot build houses for villagers on soil that may collapse at any time. That would be a joke on everyone's lives.
The tent fell into a dead silence. Everyone looked at each other. They had been dealing with Earth Release and buildings all their lives, but they were completely helpless in the face of this kind of global and deep soil structure damage. Conventional technical means and Ninjutsu applications were too insignificant in the face of this level of disaster.
Tsunade rubbed her swollen temples and felt her head hurt even more. The war was won and the people were rescued, but the village was gone. She had been Hokage for so many years and had never encountered such a difficult situation. She looked at Shikamaru and asked, "Shikamaru, do you have any ideas?"
Shikamaru's brows were furrowed. He was silent for a few seconds after hearing this. He raised his eyes and looked at Tsunade, with a hint of hesitation in his tone, but with great determination. "Lady Tsunade, there is only one person in Konoha who can solve this problem now."
Everyone's eyes were instantly focused on Shikamaru. Without him having to say it, the name instantly appeared in everyone's mind - Rinto.
But then, someone else showed a hesitant look. "But Mr. Rinto's temperament... He hates others disturbing his experiments. Before, when we sent the wreckage of Pain, he kicked us out with just a few words. Is he not willing to take care of this kind of reconstruction chore at all?"
"Yes, before Pain invaded, the village was almost destroyed, but he didn't take any action. Now if he is asked to take care of the foundation reconstruction, will he refuse directly?"
"He even saves people just to study data. How could he be interested in building a house like this?"
Discussions started, and everyone knew that Rinto's abilities were unfathomable, and he could even figure out the rules of life and death. Solving this kind of soil problem would most likely be a piece of cake for him. But the problem was that this gentleman didn't care at all whether Konoha could be rebuilt, or whether the villagers had houses to live in. If he rashly asked him, he would most likely be kicked out directly, or even annoy him.
Shikamaru waved his hand, suppressed everyone's discussion, and said, "We can't go to him in the name of 'asking him to help rebuild the village'. He is not interested in this. We have to change the angle and start from his research."
He paused and continued, "Mr. Rinto's previous research, whether it was body repair, soul anchoring, or Rinnegan's Six Paths Power, the core was to dismantle the rules and improve his theoretical system. Most of what he studied before was life forms, Chakra, soul, space gravity and other fields, and the problems we encountered this time were the transformation of the microstructure of inorganic substances, the solidification and stabilization of soil layers, and the application of Yin-Yang Release to non-living substances. These are precisely the things he has rarely had the opportunity to study systematically before."
"The entire ruins of Konoha are a unique, full-scenario experimental site. The soil damage caused by Shinra Tensei has different gradients, different types, and different geological conditions, which can provide him with massive measured samples and data that cannot be simulated in the laboratory. As long as we make it clear to him, we are willing to provide him with all survey data and meet all his experimental requirements. All test data will belong to him, and he will most likely be interested."
Shikamaru's words made everyone's eyes light up. Yes, Mr. Rinto would never take action for the reasons of "saving people" or "helping the village", but he would definitely take action for new research fields and new sample data. This was how he treated the dying and injured before, and this was how he studied the wreckage of Pain. As long as this foundation problem can meet his research needs, there will be hope.
Tsunade also made up his mind instantly and stood up suddenly. "That's right. No matter what he is doing for research or something, as long as he can solve the foundation problem, let alone provide data, even if we let him use the entire village as a testing ground, it will be no problem. Shikamaru, come with me to see Mr. Rinto, and bring all the survey reports and geological models."
"Yes."
Half an hour later, Tsunade and Shikamaru, along with two senior surveyors Earth Release Jonin, stood outside the gate of Rinto. Even though they had been here many times, they still did not dare to be lazy in the slightest, and even breathed lightly, Tsunade He raised his hand in person and knocked lightly on the courtyard door with a respectful tone. "Mr. Rinto, sorry to bother you, we have something to communicate with you about the damage to the soil in the entire area caused by Shinra Tensei."
The courtyard gate was quiet for a few seconds, and then Rinto's cold and obviously impatient voice came. "I'm not interested in rebuilding the village, don't disturb my experiment with these chores."
Sure enough, as everyone expected, Rinto's first reaction was to refuse. Tsunade spoke quickly, speaking very quickly what Shikamaru had planned in advance. For fear of being slow, the other party directly cut off the communication. "Mr. Rinto, we are not here to ask you to help rebuild the village, we are here. I have encountered a geotechnical structural problem that cannot be solved by existing technology, and I would like to ask you to take action. The entire Konoha, and the soil layer 20 meters underground, has been caused by the shock wave of Shinra Tensei to varying degrees of structural damage. From sand liquefaction, soil cracks, to deep fault slip, all damage types are covered, and it is a unique full gradient damage sample."
She paused and immediately threw out the core conditions. "We have completed the entire soil mapping, and all the geological data and damage models can be given to you. If you are willing to study the corresponding solidification plan, the entire Konoha can be used as your experiment If you need any area or any sample, we will clear it immediately and cooperate. All experimental data and test results belong to you. We only need you to provide the corresponding technical plan, and we will do all the specific execution ourselves, and we will never disturb your experiments frequently."
After finishing speaking, both Tsunade and Shikamaru held their breath and waited nervously for a response from the hospital gate. They knew very well that this was Konoha's only hope for reconstruction. Whether it could succeed or not all depended on whether Rinto was interested in these samples and data.
After more than ten seconds of silence, the courtyard door clicked and slid open silently.
Rinto stood inside the door, still wearing a clean lab coat, with no expression on his face. His eyes glanced at the thick stack of survey reports held in Tsunade's hands, and the impatience in his eyes dissipated a bit, replaced by a trace of interest in inquiry.
He was indeed not interested in the reconstruction of Konoha and the inability of villagers to live in houses. But what Tsunade said just hit a blank area in his research.
Most of his previous research on Yin-Yang Release and the rules of matter focused on living organisms. Even the mechanical transformation of Asura Path was the transformation of organic tissues into inorganic substances. As for the microstructure interference of non-living substances and the solidification and strengthening of inorganic substances, he had only made sporadic attempts before, without systematic research data support.
The global soil damage caused by Shinra Tensei is indeed a unique experimental sample. Different depths, different types, and different degrees of rock and soil structural damage allow him to systematically study the interference mechanism of Chakra on the microstructure of inorganic matter, and improve The application model of Yin-Yang Release in non-living systems can even further deepen his understanding of the original rules of matter. In the Six Paths Power model he built before, the material rewriting rules of Asura Path can be completely verified and supplemented through this research.
More importantly, Konoha will be responsible for all basic surveying and mapping, on-site execution, and data collection. He only needs to provide the core technical configuration to obtain full-scenario and full-gradient measured data, which will hardly waste too much of his core research time and fill an important gap in his theoretical system.
"Bring in the survey report and the global geological model." Rinto stepped aside, his tone still calm, without any enthusiasm for helping, only the need for research data, "Also, leave all the Earth Release solidification plans and failed test data that you have tried before."
Tsunade and Shikamaru instantly breathed a sigh of relief, and their hanging hearts completely dropped. They quickly walked into the yard and carefully placed the thick survey reports and geological model drawings in their hands beside the experimental bench in the yard. The two Earth Release Jonin also hurriedly handed over the soil samples and test data in their hands, not even daring to breathe.
Rinto picked up the top global geological map, glanced at the soil damage distribution marked on it, and lightly brushed the parameters on the drawing with his fingertips. His mind had already quickly gone through the core types and underlying logic of soil damage. For him, the cellular level of a living body Repairs can be precisely controlled. The solidification of the geotechnical particle structure of inorganic matter is essentially a simpler interference of material rules. There is no technical threshold. The only thing needed is a configuration that can be adapted to different damage scenarios and can be standardized for application, as well as complete measured data to improve his theoretical model.
"Three conditions." Rinto put down the drawings and looked up at Tsunade with a cold tone, leaving no room for negotiation. "First, the soil survey data of all areas, subsequent test data, and full parameter comparisons before and after curing must be synchronized to me as soon as possible, and no trace can be missed. Secondly,, I only provide the solidification configuration and operating specifications corresponding to the scene. The specific execution and on-site construction are all your own responsibility. If there is any problem of operational errors, please do not bother me. Third, when I need the experimental site and samples, you must cooperate unconditionally without any delay. At the same time, no one is allowed to watch or interfere with my experimental process."
"No problem! We agree to all three conditions!" Tsunade nodded immediately without any hesitation, "If you have any other requests, we will cooperate with them and will never disturb your normal research."
"Yes." Rinto responded, his eyes falling back on the thick survey report, waving his hands, and saying as if to shoo away flies, "You can leave behind the things. At this time tomorrow, come over to get the foundation solidification configuration of the core area. I will give you subsequent adaptation plans for other areas based on the detailed data you have synchronized."
"Okay, okay, we won't disturb you anymore." Tsunade responded quickly, took Shikamaru and two Jonin, quietly exited the courtyard, and carefully closed the courtyard door.
After walking far away, the few people were completely relieved. Shikamaru smiled helplessly, "Fortunately, as I expected, he is indeed interested in these sample data."
"As long as he is willing to take action, anything can be said." Tsunade looked at the few basic parameters that Rinto was holding in his hand, and his eyes were full of luck. "With Mr. Rinto's plan, we can at least shorten the reconstruction time by several years, and the stability of the foundation will be more than ten times stronger than before."
In the yard, Rinto had already taken all the survey data and walked into the laboratory.
He placed the thick report on the experimental bench, activated the light screen, and imported the three-dimensional geological model of Konoha into his computing system. On the light screen, the three-dimensional structure of the underground soil layer of Konoha was instantly displayed. Different colors marked different damage levels, soil types, and depth ranges. From complete shattering in the center area to loosening fissures in the edge areas, every detail was clearly visible.
Rinto's fingertips quickly moved across the light screen and retrieved soil sample testing data from different areas, including rock and soil particle gradation, density, moisture content, degree of liquefaction, and mechanical strength parameters. All the data was quickly disassembled, classified, and analyzed by him.
In less than two hours, he completely understood all the types of damage caused by Shinra Tensei to the soil layer this time, as well as the core reasons for the failure of the conventional Earth Release curing plan.
Conventional Earth Release: Hardening Technique essentially uses Chakra to change the physical form of the surface soil and turn loose soil into rock. This is a macro-level morphological change. It cannot penetrate into the deep soil layers at all, let alone repair the shattered rock and soil microstructure. Just like the foundation of a building has been broken, just laying a layer of cement on the ground will not solve the problem of the building collapsing.
What he wants to do is not to harden the surface layer, but to repair the damaged geotechnical structure at the microscopic level and achieve gradient overall solidification from the surface layer to the deep layer.
Rinto sat in front of the experimental table, writing quickly on the slate with the charcoal pen in his hand. Based on the rules of matter and Yin-Yang Release theory that he had already mastered, he began to design a targeted solidification configuration.
His idea is completely different from the conventional Earth Release Ninjutsu. The core is divided into three parts:
First, the microscopic particle bonding structure. Through the special Chakra frequency band, it directly interferes with the microstructure of rock and soil particles, allowing the originally loose and broken soil particles and sand to re-form a stable bonding structure, fundamentally improving the strength and density of the soil layer, instead of simply turning the soil into stone.
Second, the gradient depth conduction configuration solves the conduction loss problem of Chakra in the soil layer, allowing the Chakra configuration to be accurately transmitted to the specified depth underground, achieving controllable, layered solidification from the surface to the deep layer, and avoiding the problem of disconnection between the upper and lower layers.
Third, crack filling and structural repair configuration. For cracks, faults, and liquefied areas in the soil layer, through material reorganization mediated by Chakra, the cracks are filled, the liquefied sand soil is stabilized, the damaged stratigraphic continuity is repaired, and the entire soil layer forms a complete and stable load-bearing structure.
At the same time, he also designed adjustable parameter modules for different degrees of damage and different soil types. For example, the heavily broken soil layer in the central area is solidified with high strength and full depth; the moderately loose soil layer in the residential area is solidified with gradients adapted to the building load; and the lightly damaged areas in parks and green belts only need basic stabilization treatment to retain the water permeability of the soil layer, which can be adapted as needed.
During the design process, he also optimized the utilization efficiency of Chakra. The utilization rate of conventional Earth Release Ninjutsu and Chakra is extremely low, and most of them are dissipated in the soil layer. However, the configuration he designed can use Chakra The effective utilization rate of has increased to more than 90%. Even a Earth Release ninja of Chunin level can complete the solidification operation of deep soil layers without consuming a lot of Jonin resources as long as he masters the standardized operating procedures.
The laboratory lights stayed on all night.
Konoha outside is still staying up all night because of foundation problems, while Rinto has completed the design and simulation of the core solidification configuration, and even completed the preliminary verification of different soil layer samples in the laboratory's small simulation array, and all parameters have achieved the expected results.
Early the next morning, Tsunade and Shikamaru were waiting outside the courtyard gate early. They didn't even eat breakfast. They were both looking forward to it and anxious, fearing that Rinto would find it difficult and take longer.
As soon as the appointed time arrived, the courtyard door opened. Rinto casually threw out a seal scroll and a stack of drawings filled with parameters, operating specifications, and adaptation scenarios. He said in a calm tone, "The solidification configuration of the core area is here, divided into three gradient adaptation plans, with detailed operating specifications. First, conduct a test in a small area to confirm that the operation is OK, and then promote it to the whole area. Send the full data of the test to me as soon as it is completed."
Tsunade quickly caught the scroll and drawings, held them tightly in his arms like a rare treasure, and said quickly, "Thank you, Mr. Rinto! After we have finished testing, we will send you the data as soon as possible!"
Rinto did not respond, turned around and walked back to the laboratory, closing the door with his backhand. He was not interested in Konoha's test results or reconstruction progress. What he wanted was only the complete measured data in different scenarios after the test was completed to improve his microscopic interference model of inorganic substances.
Tsunade and Shikamaru immediately rushed back to the command tent, spread out the drawings and scrolls, and called all Earth Release Jonin and civil engineering experts. When everyone saw clearly the configuration design, operating specifications on the drawings, and the expected curing effect marked by Rinto, everyone was stunned.
They worked on the problem for more than ten days without even a clue. It took Rinto only one day and one night to come up with a complete set of solutions that could be implemented and even adapted to different scenarios. Even the details of the operation, Chakra's input parameters, and precautions were all clearly written.
"This... this is too exaggerated..." A senior Earth Release Jonin looked at the deep conduction configuration on the drawing with a face full of disbelief, "It can actually allow Chakra to accurately conduct to fifteen meters underground, and it can also control the curing intensity at different depths. This is completely beyond our knowledge of Earth Release Ninjutsu!"
"Moreover, look at the logic of this microscopic bonding. It is not conventional hardening at all, but directly changes the particle structure of rock and soil. This is no longer Earth Release, this is a regular interference with the material itself!"
"Don't be stunned! Organize manpower immediately and conduct a small-scale test in the old area of the Hokage building! See what the actual effect is!" Tsunade immediately ordered, with uncontrollable excitement in his tone.
After the order was issued, Konoha's top Earth Release ninjas immediately took action and rushed to the severely damaged area in the center of the village with drawings and scrolls. According to the operating specifications written by Rinto, several Earth Release ninjas carefully activated the solidification configuration and slowly injected the specially made Chakra into the ground.
A few minutes later, the injection of Chakra was completed. The ninja in charge of the test immediately took out professional tools and began to test the bearing capacity, compactness, and depth of the soil layer. When the test results came out, everyone took a breath, and then burst into deafening cheers.
The test results showed that the soil layer from the surface to fifteen meters underground has all been solidified. The strength of the originally loose and broken rock and soil has increased by eight times, which is stronger than the natural hard rock layer. The continuity of the soil layer is perfect, without any cracks or delaminations. It fully meets the requirements of the building foundation, and even far exceeds their previous best expectations.
The almost unsolvable foundation problem that had troubled Konoha for more than ten days was easily solved by Rinto.
The news was transmitted back to the command tent. Tsunade had been worried for more than ten days and finally relaxed completely. She immediately ordered that all Earth Release ninjas be trained in batches immediately to learn the solidification configuration given by Mr. Rinto, according to the regional division, the entire Konoha foundation repair project was fully launched. At the same time, she repeatedly reminded that the test data of each area and the comparison of parameters before and after curing must be accurately recorded and sent to Mr. Rinto as soon as possible.
In the laboratory, after Rinto received the first batch of complete data from small-scale tests, he just glanced at it and confirmed that the configuration he designed had fully achieved the expected results. He entered the data into his research system, improved the parameters of the inorganic solidification model, and then turned his attention to the next research direction-the strengthening of building materials.
Now that the foundation problem is solved, Konoha will inevitably encounter the problem of building materials. The microstructure strengthening of inorganic materials happens to be another important component in his research on inorganic rules. He has even started to deduce in advance, designing corresponding material strengthening configurations for the masonry, wood, and reinforced concrete commonly used by Konoha, and waiting for Konoha to take the initiative to send samples and data to his door.
