Chapter Summaries

Sage Fukasaku brought Rinto Mount Myōboku’s thousand-year archive of failed senjutsu cases and other research records in exchange for a safety configuration and permission to record his discoveries. Rinto began rebuilding his senjutsu model from the data, intent on understanding its risks and underlying rules.

• Sage Fukasaku visited Rinto with scrolls from Mount Myōboku and explained how Rinto’s anchoring configuration had helped Naruto stabilize his Sage Mode training.
• Sage Fukasaku offered Mount Myōboku’s complete records of failed senjutsu training in exchange for a basic safety configuration and access to Rinto’s future findings.
• Rinto agreed on condition that Mount Myōboku regularly send training data and provide its full natural-energy archives, experimental records, and sages’ training logs.
• Sage Fukasaku gave Rinto the requested materials, including Jiraiya’s notes, and Rinto studied the failed cases and questioned him about petrification, chakra types, and mental erosion.
• Sage Fukasaku returned to Mount Myōboku, convinced that Rinto could solve problems its sages had failed to resolve for a thousand years.
• Rinto moved the scrolls into his laboratory, set Jiraiya’s notebook beside the case archive, and began reconstructing his senjutsu fusion model.

Rinto conducted controlled experiments on natural energy absorption and senjutsu failure, identifying how cell affinity and assimilation capacity determined safety. After mapping petrification into three stages and explaining other forms of loss of control, he began planning a dynamic balance model for safer senjutsu chakra fusion.

• Rinto compared cell samples from different clans and backgrounds, finding that Yang Release activity shaped natural energy affinity while assimilation efficiency determined each sample’s safety threshold.
• Rinto tracked excessive natural energy through three stages of petrification, from reversible cellular imbalance to irreversible calcification.
• Rinto tested samples from multiple sources and confirmed the petrification model, while identifying weak spiritual energy as a cause of madness and sudden overload as a cause of bodily disintegration.
• Rinto reviewed Jiraiya’s notes and realized that free natural energy could accumulate before a practitioner felt any warning signs.
• Rinto wrote a plan to construct a dynamic balance model of senjutsu chakra.

Rinto developed and successfully tested a dynamic balance model that used Yin-Yang anchors to safely assimilate natural energy into senjutsu chakra. After proving the method worked in cells and on himself, he began researching a noncontact system for absorbing natural energy.

• Rinto replaced Mount Myōboku’s equal-ratio model with a dynamic system that anchored mental and physical energy and regulated natural energy through closed-loop feedback.
• Rinto calibrated the model for different constitutions and chakra types, calculating that it greatly widened the safety margin against imbalance and petrification.
• Rinto tested the model on cells from Uzumaki, Uchiha, ordinary ninja, and civilian samples, which remained stable under conditions that caused the traditional model to fail.
• Rinto activated the model in his own chakra circulation and confirmed that it produced stable senjutsu chakra even during distraction and simulated combat fluctuations.
• Rinto archived his results and began a new project to develop noncontact natural-energy absorption without bodily synchronization or transformation risks.

Rinto developed and verified a nonresonant system that captured and purified natural energy before converting it into senjutsu chakra, preventing mutation and allowing reliable use in low-energy environments. He prepared a basic version for Sage Fukasaku and turned to difficult cases from Konoha Hospital to investigate next.

• Rinto reviewed Jiraiya’s notes and Mount Myōboku’s records, identifying resonance backlash and mutation as unresolved risks in traditional senjutsu.
• Rinto designed a configuration that automatically captured natural energy, removed impurities and life imprints, and fed the purified energy into his dynamic equilibrium anchors.
• Rinto tested the configuration in a sealed incubator and confirmed it captured energy at very low concentrations with 99.99% purification precision.
• Rinto inscribed the complete system into his chakra circulation and verified that it continuously produced senjutsu chakra without mental effort, frog-like changes, or a detectable aura.
• Rinto divided the system into a basic version for Sage Fukasaku and a full version, then archived his research and began reviewing difficult cases from Konoha Hospital.

Rinto designed and validated a Senjutsu Precision Repair Configuration for extreme internal organ damage, then gave its instructions to Sakura for clinical use and data collection. As Sakura rushed to deliver it to Tsunade, Rinto considered research into toxin damage before Shikaku Nara arrived with two Nara Clan ninja carrying crates.

• Rinto studied Tsunade's records of incurable injuries and designed a senjutsu configuration to scan damaged tissue, repair it in stages, and prevent excessive cell growth.
• Rinto tested the configuration on necrotic lung tissue and other damaged samples, restoring cellular activity and repairing fine structures in repeated experiments.
• Rinto gave Sakura the configuration diagrams and instructions, requiring the hospital to send him complete clinical data while refusing to treat patients himself.
• Sakura carried the configuration to the Hokage Building to report it to Tsunade and the hospital's medical ninja.
• Rinto examined a case involving plant toxin damage and considered developing a targeted repair configuration, but Shikaku Nara arrived with two Nara Clan ninja carrying heavy wooden crates.

Shikaku Nara asked Rinto to devise a way to mature medicinal herbs in three months without losing their active ingredients, offering the Nara Clan’s inherited records and experimental data in exchange. Rinto accepted the research materials and began a new project on plant growth regulation.

• Shikaku Nara brought Rinto rare herb samples and the Nara Clan’s cultivation records, explaining that wartime demand would outstrip their medicinal reserves.
• Shikaku asked Rinto to shorten herbs’ growth cycles to three months while preserving their medicinal properties and enabling large-scale cultivation.
• Rinto agreed to develop configurations for dragonblood grass and ice lotus, requiring complete growth data, all inherited records, and no responsibility for fieldwork.
• Shikaku agreed to Rinto’s conditions and left with the Nara Clan shinobi, confident that Rinto could succeed.
• Rinto began researching plant cell growth regulation and secondary metabolite enrichment.

Rinto dissected the active-compound pathways of dragonblood grass and ice lotus, then designed and successfully tested a configuration that triggered early synthesis and enriched their medicinal compounds. He turned next to the remaining challenge: accelerating the plants’ full growth cycles without disrupting their metabolism.

• Rinto sorted the Nara Clan’s herbs and records, then chose dragonblood grass and ice lotus to study their active compounds.
• Rinto tracked the plants’ cellular metabolism and found that dragonbloodin accumulated late in dragonblood grass, while lotus-heartin required prolonged growth in low temperatures.
• Rinto designed a configuration to activate secondary metabolism early, strengthen key enzymes, and improve the storage of active compounds.
• Rinto tested the configuration in callus cells, producing high levels of dragonbloodin and lotus-heartin without harming cell growth or primary metabolism.
• Rinto optimized the configuration until the compounds reached more than 1.5 times the levels found in wild herbs, then began designing a way to compress three years of growth into less than three months.

Rinto developed and tested a Yang Release configuration that accelerated medicinal plants’ growth while keeping their medicinal potency synchronized with development. After producing mature dragonblood grass with potency far beyond wild specimens, he withheld the cultivation plan from the Nara Clan and began designing a configuration to strengthen the plants’ resilience.

• Rinto designed a three-part configuration to accelerate plant growth in sequence while balancing cell development, medicinal compounds, and nutrient supply.
• Rinto planted dragonblood grass and ice lotus seeds in a controlled experiment and embedded the growth and compound-enrichment configurations in their pots.
• Rinto recorded the plants’ rapid development and adjusted the configurations to correct a trace-element deficiency in dragonblood grass and delayed reproductive growth in ice lotus.
• After six weeks, Rinto tested a mature dragonblood grass plant and found its dragonblood compound content was 1.6 times that of three-year-old wild dragonblood grass.
• Rinto prepared cultivation plans for the Nara Clan but withheld them after finding the rapidly grown plants had weaker stress resistance than naturally grown plants.
• Rinto began designing a stress-resistance enhancement configuration for the accelerated medicinal plants.

Rinto completed and tested a modular plan for rapidly cultivating medicinal herbs that could resist pests, harsh environments, and chakra impacts, then handed it to Shikaku Nara for trial cultivation and testing. He turned next to Tsunade’s medical case records to develop a comprehensive battlefield first-aid system.

• Rinto designed and successfully tested three stackable configurations that strengthened medicinal herbs against pests and disease, environmental stress, and chakra impacts.
• Rinto combined the configurations with his growth-acceleration and medicinal-potency plans into a complete cultivation booklet for dragonblood grass and ice lotus.
• Shikaku Nara arrived with clan members, collected the plan, and arranged to harvest the first mature experimental batch and report potency and growth data to Rinto.
• Rinto shifted his attention to Tsunade’s case records and began planning a comprehensive medical-patch system for battlefield injuries.

Rinto confirmed that rapidly grown dragonblood grass had exceptionally high medicinal compound levels, but cared only about its composition data. He designed six battlefield first-aid patches and sent Sakura to arrange clinical testing, then began planning how civilians could help mass-produce them.

• A Nara Clan medicinal herb elder delivered the dragonblood grass report, which showed the forty-day crop had 162% of the pharmacopoeial compound standard and no harmful residues.
• Rinto ignored the report's medicinal assessments, recorded its composition data, and developed six patches for bleeding, pain, fractures, internal injuries, poisoning, and mental shock.
• Over three days, Rinto completed and documented the patch designs, then prepared samples for hospital testing.
• Sakura brought hospital records and news that Tsunade was training medical shinobi in Rinto's senjutsu repair configuration.
• Rinto gave Sakura the six patch samples and instructions to record clinical results and adverse reactions for him.
• After Sakura left to arrange testing, Rinto began designing a chakra-free inscription template to make mass production accessible to civilians.

Rinto finalized six battlefield medical patch designs and handed them to Sakura, who brought him clinical data on senjutsu repair. The patches were ready for production and clinical use, while Rinto became absorbed in the new research findings.

• Rinto spent two days optimizing and testing six patches for hemostasis, pain relief, bone repair, internal injuries, detoxification, and mental soothing, and prepared standard and portable versions.
• Rinto compiled the final designs, production specifications, usage instructions, and validation data into a dossier and prepared samples for Sakura.
• Sakura arrived with clinical data and positive feedback from initial patch tests, reporting that the samples had quickly eased pain and stabilized internal bleeding.
• Rinto gave Sakura the finalized designs and samples, then took the clinical data on senjutsu repair from her.
• Sakura left to deliver the designs to the Hokage Building, while Rinto studied the clinical results and forgot about the completed patch project.

Rinto completed a chakra-free civilian patch mass-production plan after Tsunade asked Konoha to increase wartime medical supplies. Tsunade ordered production to begin, while Rinto returned his attention to nerve-repair research.

• Tsunade asked Sakura to request that Rinto design patches civilians could make and use without chakra.
• Rinto agreed to study suitable materials and production methods, then designed printed configuration templates, precharged chakra, and automatic triggers for the six patches.
• Rinto tested the first samples, confirmed their effectiveness and stability, and compiled detailed instructions for mass production.
• Rinto gave the finished plan to Sakura, who was astonished by how quickly he had completed it.
• Tsunade reviewed the plan and ordered Konoha's workshops and medicinal herb shops to begin large-scale production for civilians and ninja units.
• Rinto returned to studying clinical data and developing a more precise nerve-repair configuration.

Rinto tested the medical patches under varied storage and battlefield conditions, confirming they could last at least two years when kept at room temperature and away from light. After Sakura took his report to Konoha’s logistics department, Rinto reviewed clinical feedback and began investigating why internal organ patches were less effective on some severe penetrating injuries.

• Rinto placed handmade and civilian patches in six environmental tests and an additional battlefield-impact test.
• After accelerated aging experiments, Rinto calculated that both patch types remained effective for at least two years under normal storage and for over six months in hot, humid conditions.
• Rinto compiled shelf-life and storage guidelines, and Sakura arrived with news that the first batch of one hundred thousand patches was undergoing spot checks.
• Rinto gave Sakura the stability report, and she left to deliver it to the logistics department and Tsunade.
• Sakura handed Rinto clinical data and frontline feedback, and he began analyzing why internal organ patches underperformed on some severe penetrating injuries.

Rinto created step-by-step medical patch inscription tutorials, a training plan, practice templates, and instructional sealing stones for Konoha’s medical ninja. Tsunade immediately began training them, while Rinto focused on improving an antidote patch using new clinical cases.

• Rinto divided the patch configurations into standardized modules and wrote three tutorial levels with a progressive hands-on training plan.
• Rinto prepared practice templates and sealing stones showing the inscription procedures, then gave the training materials to Sakura.
• Sakura delivered Rinto’s materials to Tsunade, who launched Konoha’s first patch inscription training program that day.
• Under Shizune and the veteran medical jonin, beginners learned to inscribe qualified bleeding-control and pain-relief patches after three days.
• Rinto studied cases of neurotoxin damage and worked to optimize the antidote patch’s nerve repair module.

Tsunade visited Rinto to formally finalize Konoha’s wartime medical reserves and thank him for his work. Rinto accepted access to Konoha’s research resources in exchange for considering future cases, then returned to his neurotoxin research as the village prepared for war.

• Tsunade and Shizune visited Rinto’s laboratory to finalize wartime medical orders and offer Konoha’s thanks.
• Rinto rejected Tsunade’s gratitude and told her that production decisions were Konoha’s responsibility, while future designs would depend on the research value of injury data.
• Tsunade offered Rinto priority access to Konoha’s medical resources, archives, experimental materials, and rare specimens, and Rinto accepted.
• Rinto refused assistants and told Tsunade to have Sakura coordinate requests for laboratory supplies.
• Tsunade and Shizune left, and Rinto resumed his neurotoxin research while Konoha continued preparing for war.

Kakashi asked Rinto to reduce Kamui’s chakra consumption and protect his eye, offering complete data on the technique in exchange. After monitoring Kamui and identifying its inefficiencies and damage to the optic nerve, Rinto gave Kakashi two detailed configurations, then began researching the underlying rules of space-time techniques.

• Kakashi visited Rinto and offered complete Kamui data in exchange for plans to reduce its chakra cost and protect his eye.
• Rinto monitored Kakashi using Kamui in several ways and scanned his left eye to record chakra flow and damage.
• Rinto identified inefficient technique-formula construction and concentrated chakra fluctuations as the main causes of Kamui’s high consumption and eye damage.
• Rinto designed an automatic formula-optimization configuration and a protective and restorative configuration for Kakashi’s optic nerve and eyeball.
• Rinto gave Kakashi the two plans and asked him to deliver the promised Kamui data; Kakashi thanked him and left with the stone tablets.
• Rinto returned to his laboratory data and began deriving the underlying formulas of space-time techniques.

Naruto visited Rinto after completing basic Sage Mode training and asked him to solve the clashes between Senjutsu and Nine-Tails chakra. Rinto tested Naruto, designed a dual-energy fusion model, and sent him away with instructions, while turning to study the collected data.

• Naruto went to Rinto's laboratory and explained that Sage Mode and Nine-Tails chakra clashed whenever he used them together.
• Rinto agreed to help in exchange for chakra data and ran tests that recorded Naruto's normal circulation, Sage Mode, and the violent clash between the two energies.
• Rinto identified problems with the Nine-Tails' will, the energies' different circulation routes, and Naruto's difficulty maintaining balance between them.
• Rinto designed a dual-anchor model with will filtering and dynamic balance regulation to let Senjutsu and Nine-Tails chakra cooperate and enhance each other.
• Rinto gave Naruto the fusion plan and told him to follow its steps, stop if problems arose, and bring back detailed experiment data.
• Naruto left excited to try the model, while Rinto reviewed the test data for insights into tailed beast chakra and Yang Release energy.

Might Guy and Rock Lee asked Rinto to treat the chronic injuries caused by years of using the Eight Gates Released Formation. After designing repair and protective plans in exchange for detailed training data, Rinto returned to studying the technique’s effects on physical energy, cells, and chakra.

• Might Guy and Rock Lee visited Rinto and asked him to repair the accumulated damage from practicing the Eight Gates Released Formation.
• Rinto agreed on the condition that they provide their complete training and medical records and continue recording their bodily changes during training.
• Rinto examined Guy and Rock Lee, identifying extensive chronic injuries and determining how opening the gates damaged their bodies.
• Rinto designed a three-session chronic injury repair plan and an adaptive configuration to reduce bodily damage without diminishing the Eight Gates Released Formation’s power.
• Rinto gave the plans to Guy and Rock Lee and instructed them to have Shizune oversee the repairs and deliver detailed records after each session and gate-opening.
• After Guy and Rock Lee left, Rinto began analyzing the examination data to investigate the Eight Gates Released Formation’s effects on physical energy, cells, and chakra.

Rinto examined Kurenai Yuhi’s Genjutsu injuries and pregnancy-related mental fluctuations, then developed protections and a stabilization system for her in exchange for detailed research data. After Kurenai left with the solutions, Rinto began studying her records to advance his research into Yin Release and the connection between mind, soul, and body.

• Kurenai Yuhi asked Rinto for protection against Genjutsu backlash and help stabilizing her mental power during pregnancy, offering complete records and ongoing data in return.
• Rinto examined Kurenai and found three fissures in her mental core, exposed chakra pathways, unstable mental power linked to pregnancy, and sluggish points in her Yin Release circulation.
• Rinto designed an adaptive three-layer defense against reflected Genjutsu and a system to repair and anchor Kurenai’s mental core, improve her chakra efficiency, and balance Yin and Yang Release.
• Rinto tested the solutions through simulations, gave Kurenai sealing tags and instructions, and required her to submit detailed weekly records.
• Kurenai accepted the solutions and left, while Rinto studied her records and examination data to deepen his research into Genjutsu, Yin Release, and the relationship between mind, soul, and body.

Rinto tested and optimized the Nara, Akimichi, and Yamanaka clans’ secret techniques, including their Ino-Shika-Cho coordination. After handing over the new configurations, he began using the clans’ records to refine his chakra research.

• Shikamaru, Choji, and Ino asked Rinto to address chakra losses, injuries, and synchronization problems in their inherited techniques, and Shikamaru provided the clans’ complete records in exchange for weekly usage data.
• Rinto tested each person’s techniques and found inefficient chakra routes in Shikamaru’s Shadow Jutsu, uneven energy distribution and poor calorie conversion in Choji’s techniques, and unrecovered mental chakra with dangerous backlash in Ino’s techniques.
• Rinto designed individual optimizations that reduced chakra loss and physical or mental risks, then added synchronization anchors to improve the trio’s coordination and stabilize their combination technique.
• Rinto simulated the configurations, gave the plans and recording requirements to Shikamaru, Choji, and Ino, and sent them away with instructions to submit data every week.
• Rinto studied the three clans’ secret technique records to fill gaps in his chakra circulation model and deepen his understanding of Yin-Yang Release.
