Chapter Summaries

Chiba explained that he had written exhaustive, hour-by-hour construction plans because the rain had left him with nothing to do. Kakashi and Hirohiko were amazed by the scrolls, while Chiba wanted them to focus on finding a way to deal with the rain.

• Chiba recalled how the torrential rain had prevented him from working on his other plans and left him with nothing to do beside Kakashi.
• Unable to find much to discuss with Kakashi, Chiba had written detailed construction scrolls to occupy himself.
• Kakashi and Hirohiko read the scrolls and were stunned by how thoroughly they covered tasks, schedules, accidents, and solutions.
• Chiba asked whether they had a problem with the scrolls, and Kakashi and Hirohiko could only marvel at his extraordinary mind.
• Chiba complained that they should stop reading and figure out what to do about the rain.

Chiba tried to get Kakashi and Hirohiko to address the rain, but they hung teru teru bozu dolls from the doorway and returned to reading. As the rain seemed to lighten, Chiba added a doll with his own face beside theirs.

• Chiba urged Kakashi and Hirohiko to find a way to deal with the rain before it disrupted their work and left the village vulnerable.
• Kakashi and Hirohiko took items from their desks and began attaching teru teru bozu dolls to the doorframe.
• Kakashi and Hirohiko reassured Chiba that their dolls would work, then went back to reading.
• Chiba sat by the doorway and worried that Yukina was overworking herself in the rain.
• Chiba noticed that the rain seemed lighter and hung a teru teru bozu doll with his own face beside the other two.

As the rain kept the group from working, Chiba mistook his wish for the storm to ease as an illusion, while Kakashi and Hirohiko planned to prepare copies of his plans. The three then noticed that the rain really had begun to let up.

• Chiba asked Kakashi and Hirohiko whether the rain had eased, and they pretended to agree while privately thinking he was imagining it.
• Chiba realized the downpour had not changed and suggested they find something useful to do while they waited.
• Kakashi explained that he and Hirohiko planned to make eight copies of Chiba's plans for teachers and students to distribute and memorize.
• Chiba agreed with the copying plan, then chose to rest while Kakashi and Hirohiko went to work.
• Kakashi and Hirohiko paused and noticed the rain had genuinely grown quieter, which Chiba confirmed.

After three days of torrential rain, Chiba and Kakashi saw the floodwaters recede and prepared to resume work the next morning. Kakashi praised Chiba’s far-reaching plan, while Chiba still lacked a foolproof way to rule out an intrusion; the chapter ended with both men heading back, ready for the work ahead.

• Chiba observed that the floodwaters were draining quickly and said the village could resume work the next day.
• Kakashi told Chiba that Hirohiko had returned to the prison and the teachers had begun teaching the distributed plan.
• Kakashi asked whether Chiba had found a way to rule out an intrusion, and Chiba admitted he had no perfect solution yet.
• Kakashi reflected on Chiba’s achievements and considered learning from his positive, persistent outlook.
• Chiba and Kakashi left the log wall to rest before the work began the following day.

Hirohiko led a group into the primeval forest to establish relay stations and transport routes, while testing whether Uchiha Itachi could keep up. Itachi passed the test, and Hirohiko began teaching him Wind Release ninjutsu.

• Hirohiko chose a site for the forward-most relay station after deciding the group should build their route step by step.
• Itachi arrived after keeping pace with Hirohiko and the three older students through the forest.
• Hirohiko confirmed that Itachi could join the group, as Chiba had instructed if he kept up.
• Hirohiko ordered the three older students to clear the level ground and assigned Itachi to stay with him.
• Hirohiko told Itachi that he would teach him several Wind Release ninjutsu.

Yamashita and the twin brothers began their tree-felling assignment and discussed whether their captain, Hirohiko, could be trusted despite rumors that he had harmed members of his clan. Convinced by Yamashita’s faith in Lord Chiba and Hirohiko’s strength, the twins resolved to seek their captain’s guidance, unaware that a watcher with crimson eyes had opened them above.

• Yamashita explained the tree-felling plan to the twin brothers, who were his childhood friends and teammates.
• The older twin asked whether their captain, Hirohiko, was reliable because he had heard Hirohiko was imprisoned for injuring Uchiha clan members.
• Yamashita admitted he was afraid Hirohiko might lose control, but said he trusted Lord Chiba’s judgment and believed Hirohiko’s strength made him a valuable captain.
• The twins agreed that they should ask Hirohiko for guidance, and Yamashita prepared to start cutting the tree.
• The older twin asked Yamashita to repeat the plan, and the three friends laughed together.
• A pair of crimson eyes opened above the children on the branch they intended to cut.

Chiba oversaw the start of the camp expansion work while worrying that an enemy spy might infiltrate the village before the training exercise ended. After realizing the project no longer needed his direct involvement, he left to resume his research.

• Chiba assigned the camp’s construction tasks to teams, relying on the written plans prepared during the rainy days.
• Chiba worried that an enemy infiltrator could exploit the seven days remaining before the residential training exercise ended.
• Chiba watched the watchtowers take shape and left Itachi’s training to Hirohiko.
• Chiba realized Kakashi, Hirohiko, and the teachers could handle the remaining work without him.
• Chiba decided to return and analyze Higan’s medicinal properties, check his blood test report, and research Sealing Jutsu.

Chiba prepared ten doses of Higan and decided to test the dangerous medicine on himself during the remaining seven days, hoping it would help him enter the Sealed Space and resolve Yukina’s problem. He returned to camp and concluded that he needed to bring Doctor Watanabe in to supervise the tests, though he still had to find a reason Minato would accept.

• Chiba found that he could not move the precision medical extraction machine or rely on numerical data to determine Higan’s effects.
• Chiba decided to conduct repeated trials on himself with the ten doses of Higan, since he could not bring himself to experiment on anyone else.
• Chiba connected a stable Higan formula to entering the Sealed Space and accelerating the removal of Yukina’s Caged Bird Seal.
• Chiba left his underground laboratory to return to camp, determined to prepare carefully so the poison would not kill him.
• Chiba decided that Doctor Watanabe was the only suitable person to assist with the tests and wondered how to persuade Minato to send him.

Chiba handed command of the Ninja Engineering Corps to Kakashi so he could work on Sealing Jutsu Formulae for someone important to him. Kakashi accepted, leaving Chiba to continue his nightly effort to memorize the formulae.

• Fifty-eight teams built more than two hundred transfer stations, expanding the transportation networks across the forest.
• Chiba returned to camp with supplies and Sealing Jutsu Formulae, then told Kakashi he would leave him in charge while he pursued important work.
• Kakashi warned that Chiba’s absence from managing the students could cause problems with their parents and disrupt the ten-day training period.
• Chiba said his work concerned the person most important to him, and Kakashi agreed to take command despite knowing it was a personal matter.
• Kakashi went to sleep, while Chiba organized the formula scrolls and reviewed them to strengthen his memory.

Chiba welcomed Doctor Watanabe to the Ninja Engineering Corps' camp and showed him the new infirmary. He asked the doctor to supervise a trial of Higan on himself, and Doctor Watanabe reluctantly agreed to monitor him and save him if anything went wrong.

• Chiba apologized to Doctor Watanabe for the difficult route and led him to the camp infirmary.
• Doctor Watanabe inspected the beds and medicine cabinets and praised the infirmary.
• Chiba told Doctor Watanabe that he wanted to test Higan on himself, but the doctor strongly opposed the dangerous trial.
• Chiba pleaded with Doctor Watanabe, who agreed to watch over him and save him if necessary.

Chiba entered the Sealed Space after taking Higan and found that memorizing Sealing Jutsu Formulas had become remarkably easy, though he could not explain why. He worried about the dwindling supply of rare ingredients and the trouble that might follow, then rested to see whether he could memorize more.

• Chiba took Higan under Doctor Watanabe’s supervision and entered the Sealed Space to memorize the Sealing Jutsu Formula.
• Chiba found he could quickly break down and memorize formulas, while previously learned ones also became clearer in his mind.
• Chiba realized his memory seemed to have changed but could not determine the cause, and accepted the improvement because it helped him.
• Chiba calculated that only nine doses remained and worried that the scholars might notice the depleted herbs and report him to the Hokage.
• Chiba rested, hoping his improved memory would let him memorize more of the formula during the remaining doses.

Chiba completed another trial of Higan and confirmed that it induced a stable, ten-minute feigned death. He took the preserved blood samples to analyze the drug, while Doctor Watanabe stayed behind wishing he could study its data himself.

• Chiba woke after ten minutes in Higan's feigned death state and asked Doctor Watanabe about the trial.
• Doctor Watanabe confirmed the timing matched the previous test and drew blood samples from Chiba.
• Doctor Watanabe reported that Chiba had shown no breathing or pulse, though a physician could still identify clues that he was not truly dead.
• Chiba took the preserved blood samples to analyze Higan's medicinal properties and vanished in a flash.
• Doctor Watanabe watched Chiba leave and wished he could study the drug's data first.

After testing Higan, Chiba discovered that his body metabolized the deadly poison within ten minutes, an unexplained change that frightened him. Worried that the same unknowns could hinder his training and plans to face Obito, he hurried to consult the old scholars, whom he encountered leaving the neighboring laboratory.

• Chiba analyzed Higan residue in his blood and found that his body cleared the poison in ten minutes instead of the expected half hour.
• Chiba concluded that he had gained extreme resistance to toxins, likely from an unknown bodily change after his near-death experience.
• Chiba worried that the change might affect his ability to extract Chakra and make his combat calculations unreliable.
• Chiba considered the coming Nine-Tails attack and decided he had to strengthen himself and prepare tactics against Obito's space-type Mangekyō Sharingan.
• Chiba packed his data, cleaned up the laboratory, and rushed out to find the old scholars, whom he saw leaving the laboratory next door.

Chiba received and began reading the completed research report on his body, while a sinister man in a hidden underground laboratory abandoned his attempt to steal the data. The sinister man said his experiment had succeeded and watched a specimen’s many eyes open in a jar.

• The old scholars handed Chiba the research papers on his body and left to sleep.
• Chiba returned to the analysis room and read the report, growing increasingly serious as he studied the data.
• In a hidden underground laboratory, a sinister man learned that Chiba had obtained the final research data and decided to leave it alone.
• The sinister man said his experiment had succeeded and looked at a hand specimen whose many red eyes opened and turned toward him.

After studying nearly three hundred pages of medical research, Chiba learned that his cells were dividing and consuming one another at abnormal rates, though he could not determine what was happening. He traced his increased Chakra and strength to a thousandfold rise in cellular activity, and resolved to investigate why he still could not use Eight Gates Mode.

• Chiba reviewed the research reports and suspected that his abnormal cell division and cell consumption might be cancer.
• Chiba concluded that the data required further study and planned to ask the researchers to explain their specialized terminology.
• Chiba learned that his cellular activity had increased by 1000%, allowing him to extract more bodily energy and maintain Jonin-level Chakra.
• Chiba linked his increased strength, speed, and Chakra-condensing speed to his heightened cellular activity.
• Chiba found that his body had no deformities and that the Eight Gates remained intact, so he considered retraining Eight Gates Mode while investigating what blocked its use.

Chiba returned to camp after analyzing how his body had changed following the drug test, concluding that his strength, Chakra, healing, and poison resistance had improved. He healed a student's cut, then alarmed Doctor Watanabe by saying that he—not the drug—had a problem.

• Chiba finished analyzing his cell data and inferred that his body had gained greater strength, Chakra, self-healing, and resistance to poison and illness.
• Chiba returned to the medical building and found Doctor Watanabe bandaging a female student's superficial cut.
• Chiba healed the student's wound with Medical Ninjutsu and told her to be more careful, leaving her flustered and rushing out.
• Doctor Watanabe asked how the drug test had gone, and Chiba replied that the drug was fine but he had a problem.
• Doctor Watanabe grabbed Chiba's arms in alarm and demanded to know what had happened to him.

Chiba explained that his toxin resistance caused Higan’s effects to differ, ending the need for further drug tests. With Doctor Watanabe staying to oversee medical care at the engineering site, Chiba turned to studying the Sealing Jutsu Formula.

• Doctor Watanabe learned that Chiba’s toxin resistance had let him survive Higan and wake without CPR, and warned him not to joke about such matters.
• Chiba decided there was no need for further tests of Higan’s effects.
• Doctor Watanabe asked whether he should remain at the site, and Chiba explained that the engineering team needed a full-time doctor.
• Doctor Watanabe went to inspect the storeroom and familiarize himself with the medical supplies.
• Chiba began writing down the Sealing Jutsu Formula from memory.

Chiba ignored dinner and immersed himself in studying Sealing Jutsu Formulas while Kakashi watched over him and worked on a summary. Chiba’s understanding of Sealing Jutsu and Curse Mark Jutsu rapidly advanced as he broke down and recombined the formulas in his memory.

• Kakashi brought injured students to Doctor Watanabe for treatment, then learned that Chiba had skipped dinner while studying.
• Doctor Watanabe left Chiba in Kakashi’s care, and Kakashi worried about the rain and the unresolved threat of infiltration.
• Kakashi trusted Chiba to find a solution and began writing a summary while Chiba remained absorbed in his work.
• Chiba mentally broke apart and recombined Sealing Jutsu and Curse Mark Jutsu Formulas, rapidly gaining new knowledge and mastery.

Chiba discovered that after reviewing his recorded Sealing Jutsu, he had suddenly gained an extraordinary ability to understand, use, and create sealing techniques. He concluded that a previously unnoticed transmigrator perk had awakened.

• Chiba realized he had mastered every Sealing Jutsu he had recorded after studying them for five hours.
• Chiba found he could combine familiar formulas in new ways, improve their effects, and develop new Sealing Jutsu.
• Chiba compared his sudden advancement with the difficulty of mastering Sealing Jutsu and Minato Namikaze's formidable skill.
• Chiba concluded that he had activated a transmigrator cheat and bitterly wondered how he had forgotten transmigrators were supposed to have perks.

Chiba reflected on his recent discovery, then reviewed Kakashi's construction report and recognized the need to remain publicly responsible for the camp. He promised Kakashi a proposal to guard against an early invasion within three days, while Kakashi ended the discussion by going to sleep under his desk.

• Chiba composed himself after his discovery and listened as Kakashi handed him the construction report.
• Chiba read the report and told Kakashi to keep directing construction, while Kakashi reminded him to remain the public face of the operation.
• Chiba approved the progress, noting that nearly fifteen transfer stations and connecting roads had been completed that day.
• Chiba promised to give Kakashi a proposal addressing the risk of an early invasion in three days.
• Kakashi accepted the deadline, then crawled beneath his desk and went to sleep.
