Chapter Summaries

Uchiha Yu continued training Uchiha Shisui while investigating the next stage of his Immortal Path cultivation. He discovered that his recent anger and stubbornness came from a growing Spleen Pig within his mind, and wondered how to control it.

• Obito ended the training assignment early, while Shisui continued training with Yu and began studying independently from Yu's scrolls.
• Shisui earned Miwa Masayo's trust by generously paying for meals, replacing damaged items, and helping with household chores.
• Yu considered the coming breakthrough in Foundation Establishment and worried about which Natural Energy attribute might follow Earth, since Metal-Attribute Natural Energy did not exist in the Ninja World.
• Yu inspected his mind after noticing his unusual anger toward Obito and found that his Dangkang had become a fat domestic pig.
• Yu concluded that the Spleen Pig could influence his behavior by making him greedy, conservative, and intolerant of defiance, and wondered how to suppress it.

Uchiha Yu struggled through the night to balance and subdue the Heart Monkey and Spleen Pig in his mind, then went running despite his exhaustion. His grueling run brought his thoughts into a deep tranquility.

• Uchiha Yu found that suppressing the Heart Monkey fed the Spleen Pig, while retreating thoughts strengthened the pig and threatened his control.
• Uchiha Yu used the Heart Monkey’s fur and the opposing mind forms’ emotions to weaken the Spleen Pig and maintain balance between them.
• Uchiha Yu repeatedly shifted his state of mind to keep the Golden Snub-nosed Monkey and Dangkang from overpowering each other, eventually subduing both.
• Uchiha Yu woke at dawn exhausted, but the thought of skipping his run unsettled his balance, so he added a lap and went out carrying more than six hundred kilograms of weights.
• Uchiha Yu’s physical exhaustion focused his mind during the run, leaving him in an unusually light and tranquil state.

Uchiha Yu developed the combat-supporting divine ability Free and Easy Wandering during a weighted run, giving him confidence that he could evade attacks even when surrounded. He then prepared a whole Nara deer for roasting in a sealed fire pit and offered the mud-covered Miwa Masayo a hot bath while the meat cooked.

• Uchiha Yu fused Omniscient Mind's Eye, intuitive judgment, and Lightning Reflexes into Free and Easy Wandering, which let him evade obstacles and suppress intense emotions.
• Uchiha Yu returned home and decided to roast the premium Nara deer Shisui had sent him before its meat spoiled.
• Uchiha Yu and the Tabby Cat discussed cumin powder while he coated the deer in a seasoned flour paste.
• Uchiha Yu dug a fire pit with Earth Style, lowered the bound deer inside with hot charcoal and salted water, then sealed the pit to roast it for forty-five minutes.
• Miwa Masayo got covered in mud while helping, and Uchiha Yu offered her a hot bath.

Uchiha Yu welcomed Uchiha Nobutada to lunch and served him pressed tofu and venison, giving the elderly man his first satisfying solid meal in years. As the meal continued, Nobutada watched Yu devour meat and bones with astonishing speed and regretted not caring for his teeth when he was young.

• Shisui brought Uchiha Nobutada to Uchiha Yu's home, where Yu prepared soft food for the elder's loose teeth.
• Uchiha Yu pressed silken tofu into a firmer texture and set out a formal lunch with venison, tofu, and seasonings.
• Uchiha Nobutada ate the tofu eagerly and said it was delicious, while struggling to chew the tender venison.
• Shisui, Miwa Masayo, and Uchiha Yu dug into the meal, with Yu slicing meat for them and crunching through ribs and bones himself.
• Uchiha Nobutada watched Yu's powerful teeth and regretted that he had not protected his own teeth when he was young.

Uchiha Nobutada taught Uchiha Yu and Shisui an aggressive longsword style, and Yu quickly grasped its underlying principles. Before leaving, Nobutada asked Yu to teach Shisui the swordsmanship after he awakened his Sharingan, then tricked Yu into revealing his thoughts about Kagami Uchiha.

• Uchiha Nobutada demonstrated his longsword techniques while Uchiha Yu concealed his Three-Tomoe Sharingan with Genjutsu and copied the movements.
• Uchiha Yu identified eight basic ways to apply force in the sword style and understood how its techniques centered on thrusts and taps, while Shisui struggled to follow.
• Uchiha Nobutada performed the sword movements a second time in a different sequence, and Yu used his Sharingan to memorize and analyze them.
• Uchiha Nobutada asked Yu to teach Shisui the swordsmanship after Shisui awakened his Sharingan, and explained that Yu's ocular power was leaking beyond his control.
• Uchiha Yu promised to look after Shisui, then began to comment on how dangerous people's hearts were before realizing that Nobutada had feigned sorrow about Kagami Uchiha to draw him out.

Uchiha Nobutada explained why he believed Kagami Uchiha had been betrayed and described how Konoha’s policies against the Uchiha had weakened the village and pushed the clan toward disaster. He entrusted Uchiha Shisui to Uchiha Yu, who accepted the responsibility because he wanted to protect the clan and preserve his own secrets.

• Uchiha Nobutada told Uchiha Yu that the old Uchiha had lost influence and that Kagami Uchiha had likely been betrayed by someone he trusted.
• Uchiha Nobutada argued that Senju Tobirama’s efforts to weaken the Senju and Uchiha had helped Konoha grow, but later leaders had pushed those policies too far.
• Uchiha Nobutada described Konoha’s military decline and the Uchiha clan’s worsening treatment as consequences of the village’s internal strife.
• Uchiha Nobutada bowed to Uchiha Yu and entrusted Uchiha Shisui’s safety to him.
• Uchiha Yu accepted the responsibility, recognizing that protecting the Uchiha clan would also help keep attention away from his unusual circumstances.

Uchiha Nobutada entrusted Uchiha Yu with seven chests of wealth gathered by the Uchiha elders and Uchiha Madara, hoping he would revive the clan. After seeing the fortune, Uchiha Yu accepted the task and decided to hide most of it.

• Uchiha Yu visited Shisui's mansion at midnight and found Uchiha Nobutada waiting with seven chests.
• Uchiha Nobutada explained that the chests belonged to him, several other elders, and Uchiha Madara, and that the elders had gambled on Uchiha Yu coming to claim them.
• Uchiha Yu accepted the burden of reviving the Uchiha clan, reasoning that Shisui could help protect and unite it under his guidance.
• Uchiha Nobutada opened all seven chests, and Uchiha Yu and Nobutada discovered the fortune was worth at least as much as the clan's publicly known assets.
• Uchiha Yu proposed hiding everything except the gold and cash, and assured Uchiha Nobutada that he had a way to do it.

Uchiha Yu moved the hidden clan wealth and stopped Uchiha Nobutada from killing himself, explaining that death could not protect secrets from the Impure World Reincarnation Jutsu. He erased the old man’s recent memories and left him alive to prevent the wealth’s location from being exposed.

• Uchiha Yu realized the wealth’s assets were prepared for the Uchiha clan and could be used if he became clan head and partnered with Cat Castle’s commercial network.
• Uchiha Yu transferred most of the goods with Storage Scrolls and prepared to erase the remaining traces.
• Uchiha Nobutada revealed poisoned wine and said he would kill himself to protect the secret, but Uchiha Yu took the bottle away.
• Uchiha Yu used Natural Energy to destroy the Sealing Jutsu Nobutada was activating and explained that the Impure World Reincarnation Jutsu could expose secrets even after death.
• Uchiha Yu said Nobutada’s shallow memories could still be erased and used his Sharingan to overwrite them with false memories, leaving the old man alive.

Uchiha Yu and Miwa Masayo discussed how to invest their enormous fortune without drawing the Sarutobi Clan’s attention. Later, Uchiha Yu showed Uchiha Shisui how the Uchiha could estimate Konoha’s grain reserves indirectly, while the clan remained unaware that the drop in grain prices signaled completed war preparations.

• Uchiha Yu explained to Miwa Masayo that their fortune was too large to spend openly, so they planned to invest part of it through Cat Granny and use some to develop medicinal food.
• Miwa Masayo and Uchiha Yu agreed to take three percent returns on a portion of their money and buy medicinal herbs through Cat Granny.
• In September, the Uchiha clan concluded that war probably would not break out that winter and adjusted its grain and weapons stores.
• Uchiha Nobutada criticized Uchiha Fugaku and the elders for failing to recognize that grain prices had fallen because the Great Nations had finished preparing for war.
• Uchiha Yu advised Uchiha Shisui to use Military Police Force records of grain warehouses, shipments, and population to estimate Konoha’s reserves without directly requesting military intelligence.

Uchiha Yu’s medicinal cuisine helped Shisui and Miwa Masayo grow stronger, while Uchiha Yu warned Xin Yin that changing times would prevent recipes from preserving clan power. The Third Kazekage’s disappearance ended Yu’s expectation of a quiet life at home.

• Uchiha Yu used medicinal cuisine to nourish Shisui, Xin Yin, and Miwa Masayo, and Shisui made rapid physical and chakra gains through weighted training.
• Uchiha Shisui and Uchiha Xin Yin discussed the clan elders’ use of medicinal cuisine to strengthen the main family, and Uchiha Yu argued that the changing Ninja World would upend any lasting hierarchy.
• Uchiha Yu stopped Shisui’s training after forty minutes, removed his weights, and massaged him before sending him home with Xin Yin.
• Uchiha Yu began private stance training that surrounded him with dense Fire-Attribute Natural Energy to advance his bodily evolution.
• Miwa Masayo brought Uchiha Yu news that the Third Kazekage had disappeared, and Yu realized his quiet days at home were over.

Uchiha Yu learned that the Third Kazekage had been missing for nine days and feared the coming war would leave Konoha’s front line exposed, so he arranged to leave the village with Miwa Masayo. After preparing for ten days, he departed feeling powerful and free, while Shisui discovered dangerous writings in Yu’s scrolls and secretly destroyed them.

• Miwa Masayo told Uchiha Yu that the Third Kazekage had not appeared for nine days, and Yu recognized it as a warning of the coming war.
• Uchiha Yu decided to avoid the danger by taking a long, solo mission outside the Land of Fire, and Miwa Masayo agreed to go with him.
• Uchiha Yu spent ten days processing his supplies, hiding valuables, and preparing Uchiha Shisui’s training plan and scrolls before leaving Konoha with Miwa Masayo.
• Uchiha Yu departed with confidence in his Three-Tomoe Sharingan, ninjutsu, and Foundation Establishment strength, believing he could face even a Kage-level enemy.
• Uchiha Shisui found dangerous material in Yu’s scrolls, copied and memorized it, then destroyed the evidence to protect his brother.

Uchiha Yu traveled with Miwa Masayo to Cat Castle after learning that the Ninja Cats could no longer absorb Natural Energy, and Root ninja discovered his reverse summoning. He ambushed the Root team, killed them, and staged their deaths to implicate Sunagakure before disappearing without a trace.

• Miwa Masayo told Uchiha Yu that she had expelled the Ninja Cats' Natural Energy to prevent mutations, leaving them unable to absorb it, and Yu decided to visit Cat Castle to help.
• Miwa Masayo reverse-summoned Uchiha Yu to Cat Castle while three Root ninja investigated where he had vanished and sent a report to Danzo.
• Uchiha Yu caught the Root ninja's messenger hawk, immobilized the team with Genjutsu, and learned that their leader had not received Root's Cursed Seal of Ridding.
• Uchiha Yu used Genjutsu to plant suspicion of an Uchiha spy and Sunagakure, then killed the Root ninja and staged their deaths to resemble attacks by Sunagakure puppet masters.
• Uchiha Yu erased the traces of his Sharingan and reverse-summoned himself away.

Uchiha Yu reflected on why he would delay confronting Danzo and decided that patience better served his growing power. At Cat Castle, he learned that Maoyu was severely injured after attempting to cultivate Senjutsu and went to see him.

• Uchiha Yu recalled that he had used an outdated Sharingan clone technique against Root because he had never learned the Shadow Clone Technique.
• After dispelling the clone and absorbing its experiences, Uchiha Yu resolved to let time weaken Danzo rather than risk an early confrontation.
• Uchiha Yu and Miwa Masayo agreed that Miwa would join him when he eventually made his move against Danzo.
• Uchiha Yu and Miwa Masayo arrived at Cat Castle, where Cat Granny was overseeing Kura Weapon Shop.
• Miwa Masayo explained that Maoyu had accumulated substantial Natural Energy, suffered severe injuries during Senjutsu cultivation, and could no longer get up.
• Uchiha Yu decided to visit Maoyu, whose strength served as Cat Castle's martial protection.

Uchiha Yu examined Maoyu and found that excess Natural Energy had blocked the Ninja Cat’s spine, leaving him paralyzed. Yu forced the energy to flow again and controlled it as it mixed with Maoyu’s chakra, and Maoyu celebrated becoming a sage.

• Uchiha Yu entered Maoyu’s room with Miwa Masayo and startled the paralyzed cat.
• Uchiha Yu petted and examined Maoyu, discovering that accumulated Natural Energy was blocking nerve transmission along his spine.
• Uchiha Yu vibrated Maoyu’s spine to break up the blockage, then controlled the surging Natural Energy to keep it from harming him.
• Maoyu instinctively used his chakra to resist the pain, causing it to combine with Natural Energy and form Sage Chakra.
• Maoyu excitedly declared himself a sage and promised to look after Uchiha Yu.

Uchiha Yu saved Maoyu from excess Natural Energy and helped him complete his evolution into the second Cat Sage. Cat Granny then entrusted Maoyu with leading Cat Castle, with Uchiha Yu confirming the decision.

• Miwa Masayo attacked Maoyu for claiming Uchiha Yu backed him, but Uchiha Yu grabbed Maoyu and stretched him into a ring to control his Natural Energy.
• Uchiha Yu expelled the excess Natural Energy while preserving Maoyu’s Sage Chakra, allowing the transformation to finish and making Maoyu the second Cat Sage.
• Maoyu learned to identify wind-attributed Natural Energy, and Uchiha Yu judged that he could eventually challenge Gamabunta and Manda.
• Cat Granny returned to Cat Castle, praised Maoyu’s transformation, and proposed entrusting him with the leadership.
• Maoyu objected that Miwa Masayo deserved the position, but Miwa Masayo supported him and Uchiha Yu declared Maoyu more suitable to lead.

Uchiha Yu advised Maoyu to unite the ninja beast clans against Ryūchi Cave and Mount Myoboku, whose sage summons monopoly was threatened by Cat Castle’s new sages. Maoyu agreed to form the Warm-Blooded Immortal Alliance, and White Ape arrived seeking an audience.

• Enma and White Ape discussed allying with the Cat Sages and learning Senjutsu to challenge the cold-blooded sage regions.
• Uchiha Yu told Maoyu to contact every ninja beast force and form an alliance, despite the Ninja Wolf Clan and Falcon Clan having harmed Cat Castle.
• Uchiha Yu explained that Ryūchi Cave and Mount Myoboku would target Cat Castle because its new sages threatened their control of human summoning contracts.
• Uchiha Yu argued that the Diamond Ape Clan, Ninja Wolf Clan, and Falcon Clan would join for profit and protection, and Maoyu accepted the plan for a Warm-Blooded Immortal Alliance.
• A ninja cat reported that White Ape of the Diamond Ape Clan had arrived to meet Maoyu.

Uchiha Yu helped Maoyu establish the Warm-Blooded Immortal Alliance, with Cat Castle leading the other clans through shared training, defense, and business. Meanwhile, Mount Myoboku identified a mysterious human sage as its enemy and alerted Jiraiya and Ryūchi Cave, where the White Snake Sage ordered Manda not to kill toads.

• Maoyu and the Diamond Ape, Ninja Wolf, and Falcon clans formed the Warm-Blooded Immortal Alliance, recognizing the Ninja Cat Clan as their leader.
• Uchiha Yu explained that Cat Castle needed superior strength and a steady flow of benefits to maintain control of the alliance.
• Gamamaru foresaw a black-haired human male sage threatening Mount Myoboku and ordered Sage Fukasaku to warn Jiraiya and send Spy Frogs to investigate.
• Sage Fukasaku planned to notify Jiraiya and asked Sage Shima to warn Ryūchi Cave to restrain its snakes.
• The White Snake Sage explained that Mount Myoboku and Ryūchi Cave shared a fate against outside enemies, then ordered Tagitsuhime to stop Manda from dealing fatal blows to toads.

Uchiha Yu and Miwa Masayo left Cat Castle after Yu built an altar to help the Ninja Cats cultivate Senjutsu, and he reflected on the three safe havens he still needed to establish. On his way to Jiusen Village in the Land of Rivers, Yu avoided numerous disorganized Sunagakure ninja and arrived late at night.

• Uchiha Yu built a huge Natural Energy altar at Cat Castle, where eight Cat Sages could cultivate at once, and discussed its limitations with Miwa Masayo and Maoyu.
• Uchiha Yu left Cat Castle with Miwa Masayo and headed for Jiusen Village to continue his mission.
• Uchiha Yu considered how the Uchiha clan and Cat Castle were inadequate as his first two burrows and resolved to keep searching for a secret location for a third.
• Uchiha Yu encountered many Sunagakure ninja crossing the Land of Rivers and suspected that the Third Kazekage's disappearance had thrown the village into disorder.
• Uchiha Yu evaded the Sunagakure ninja and reached Jiusen Village late at night.

Uchiha Yu investigated the low water in Jiusen Village’s river and suspected a landslide had blocked a tributary, then hurried upstream after realizing a newly formed Barrier Lake could burst and endanger the villagers. He found the cause of the reduced flow after racing nearly two hundred and sixty kilometers upstream.

• Uchiha Yu met Jiusen Village’s chief, learned the river had become too shallow for log rafts, and questioned him about recent changes.
• Uchiha Yu learned that an earthquake and muddy flash flood had occurred six days before the water level dropped, leading him to suspect a landslide had blocked a tributary.
• Uchiha Yu dealt with his agitated Heart Monkey overnight, while Miwa Masayo worried that its episodes were growing more frequent.
• Uchiha Yu recognized that a newly formed Barrier Lake could collapse into a devastating flood, so he raced upstream to protect the village from a possible disaster.
• Uchiha Yu traveled nearly two hundred and sixty kilometers upstream and found the cause of the river’s flow being cut in half.

Uchiha Yu and Miwa Masayo found that the new lake had unusually concentrated Natural Energy and decided to preserve it. Yu built a winding drainage channel through the natural dam, and Miwa cleared its underwater entrance, safely lowering the lake’s water level.

• Uchiha Yu and Miwa Masayo sensed the lake’s rising Natural Energy and agreed to protect the lake and claim the area for Cat Castle.
• Uchiha Yu inspected the rubble dam and planned a winding channel to release the water without letting it erode the dam.
• Uchiha Yu used Sage Art: Grouting Cement to create a reinforced drainage pipe through the dam and into the original riverbed.
• Uchiha Yu exhausted himself building the pipe and asked Miwa Masayo to remove the boulder blocking its entrance.
• Miwa Masayo used her blue flames to split the submerged boulder, allowing lake water to rush into the pipe and avert the crisis.
