Chapter Summaries

After Gabriel defeated the Book Demon, the team discussed the imprint information and how to distribute it if they entered Perfect Clear Mode. Angel discovered that the Echo Library’s observer was watching them and overheard her approving Gabriel’s suggestion to share the imprints, leaving Rabbit Girl and Angel with a likely answer for the future.

• Gabriel explained that its Dark Word Spirit had made the Book Demon drop its book, and Angel argued that special talents could defy reason.
• Gabriel revealed that it had received an imprint prompt after defeating the Book Demon, but imprinting the information required Perfect Clear Mode.
• Rabbit Girl and Gabriel weighed whether imprints should be concentrated or distributed, and Gray Porcelain reluctantly agreed to challenge a Book Demon if needed.
• Rabbit Girl asked whether the team should follow the navigation cursor or Angel, and Angel chose the cursor after spotting the observer watching them.
• Angel told Rabbit Girl that the observer had heard their discussion and favored Gabriel’s proposal to distribute the imprints; they agreed to keep the information from the others.

Angel and his companions discovered that repeated proverbs in Echo Library corresponded to furnishings in hidden spaces, and Angel deduced that each floor contained only three distinct proverbs. After verifying the pattern and continuing their search for Book Sprites, they reached a fork where the right path led to a hidden space containing a stone stele.

• Rabbit Girl, Gabriel, and Gray Porcelain found the same proverb about brush and ink repeated on three different tables, and Rabbit Girl proposed that the repetitions might be a poetic device.
• Angel noticed that the repeated proverb had appeared on tables, while a different proverb had appeared on paper, and he secretly used God's-eye view to inspect the library’s hidden spaces.
• Angel told Rabbit Girl that each floor held only three distinct proverbs, and the group verified that paper in a hidden space produced the proverb about carving words.
• Gray Porcelain concluded that tables and paper predicted repeated proverbs, so the group planned to skip matching Book Demon trials and focus on Book Sprites.
• Angel defeated another Book Sprite, and the group continued along the locator cursors while verifying the proverb pattern and bypassing one Book Demon trial.
• Angel and Rabbit Girl reached a fork where the left path led to a Book Sprite and the right path led to a Book Demon whose hidden space contained a stone stele.

Angel faced a Book Sprite’s combat trial against a Ghostfang Orc, which could only be defeated by striking its weak points with ordinary strength. After learning from Luolun that the orc’s neck held vulnerable compensatory blind spots beneath its exposed armor, Angel struck both sides of its neck and passed the trial.

• Rabbit Girl split the group between the two corridors, and Angel went left while Gray Porcelain stayed behind.
• Angel found a war-themed gallery and was pulled into a black space, where the Book Sprite summoned a Ghostfang Orc for a combat trial.
• Angel inferred from a painting that the Ghostfang Orc’s tusks were weak points, then asked Luolun for help and learned that the vulnerable spots were on both sides of its neck.
• Angel began the battle, dodged the Ghostfang Orc’s attack, and struck both sides of its neck, causing it to collapse and disappear.
• The Book Sprite congratulated Angel for passing the trial and created a positioning beacon for him.

Angel and his team found all hidden information on the first floor of the Echo Library, discovered an unselectable hidden quest, and located the floor’s rift. They needed to choose someone powerful enough to stay and guard it while the team found the other rifts.

• Angel used the Guidance Radar to narrow down the rift’s location, then rejoined Gray Porcelain and Rabbit Girl.
• Rabbit Girl showed the team a hidden space containing a new aphorism, and the Text Panels announced that they had found all hidden information and unlocked a hidden quest they could not accept.
• Rabbit Girl guessed that the quest could only be accepted in Perfect Clear Mode, and Angel agreed they would learn the truth when they reached it.
• Angel completed another Book Sprite trial, adding a marker that pinpointed the rift, and led the team to it.
• Angel explained that someone would have to guard the rift while the others found the remaining rifts, leaving Rabbit Girl and Gabriel as the possible guards.

Angel led Gabriel and Gray Porcelain to Echo Library’s second floor, where he explained the Shell Books stored in its simulated waterways. He then left them behind to take a Book Sprite’s trial, while Rabbit Girl stayed on the first floor to face the Book Demon.

• Rabbit Girl and Gabriel argued over who should stay behind, but Angel explained that both choices led to a fight with the Book Demon, so Gabriel followed him upstairs.
• Angel used a spiral staircase to lead Gabriel and Gray Porcelain through a ceiling opening and into the second floor of Echo Library.
• The group discovered a simulated waterway with Shell Books, and Angel showed Gray Porcelain how a Memory Pearl stored a library of books.
• Angel explained that Shell Books preserved Memory Pearls inside living Memory Clams and that the second floor held collections from many races.
• Angel sensed a Book Sprite outside the waterway and went to take its trial, telling Gabriel and Gray Porcelain to wait and check on Rabbit Girl through team chat.

Angel passed the Book Sprite’s trial, reunited with Gabriel and Gray Porcelain, and led them toward a Book Demon. After Rabbit Girl reported the tower’s attack schedule, Angel and Gabriel solved a hidden-space riddle and uncovered a piece of woven cloth; Gabriel was then chosen for the Book Demon challenge.

• Angel freed Gray Porcelain from Gabriel, and the three continued through the corridors toward a Book Demon.
• Rabbit Girl reported that she had defeated three Book Demons in succession and explained when future tower attacks would occur.
• Gray Porcelain refused to enter the simulated water area for now, so Angel and Gabriel went on without it.
• Angel found three Memory Pearls linked to guilds and placed them in a mural to reveal a hidden space containing woven cloth.
• Gabriel fell silent after Gray Porcelain called for it, having been chosen for the Book Demon challenge.

Angel, Gabriel, and Gray Porcelain chose a shortcut through a mechanism corridor after Angel's inspiration revealed it would lead to the boundary zone faster. They passed two mechanisms and reached a crystal curtain puzzle that required filling a marked glass bottle with water.

• Angel sent the defeated Book Demon's maxim, "I guarded the tomes to preserve the truths He had scattered," to the team chat.
• Angel told Gabriel and Gray Porcelain that a shortcut led to the boundary zone, and the group voted to take it despite the risk of difficult mechanisms.
• Angel led the group through a moon Doodle on the wall and into the narrow mechanism corridor.
• Gabriel found four weak spots in the first wall puzzle and struck them together, causing the wall to collapse and opening the path.
• Angel, Gabriel, and Gray Porcelain reached a crystal curtain with a mermaid statue and a marked glass bottle, whose puzzle required filling it with water.

Angel and his companions advanced through the mechanism corridor by using Gabriel’s abilities to clear a time-consuming jigsaw puzzle, then relied on Rabbit Girl to solve a difficult question about Zuri Kodesa Script. They left the stage wondering whether the puzzles ahead would become easier, while Angel suspected the hardest challenge would not offer a chance to guess.

• Angel filled the bottle to the marked level, dispelling the crystal curtain, and the group reached a corridor covered in jigsaw pieces.
• Angel explained that the short route balanced its distance with time-consuming puzzles, while Gabriel assembled the pieces on the door in under a minute.
• Gray Porcelain and Gabriel exchanged insults about Gabriel’s computational power and intelligence as the group continued onward.
• The group found a multiple-choice question about the meaning of a Zuri Kodesa Script symbol, and Angel realized the books provided no fixed answer because the script relied on personal associations.
• Rabbit Girl analyzed the symbol through the team chat and identified option four, allowing the group to clear the stage.
• Gray Porcelain wondered whether the question had been the corridor’s hardest, and Angel said he doubted the hardest question would let them guess.

Angel, Gabriel, and Gray Porcelain reached Nomephins' Sighing Wall, where a dangerous maze trial offered a shortcut through the Mechanism Corridor. Gray Porcelain volunteered to tackle the maze and was swallowed by Nomephins, leaving Angel and Gabriel waiting outside as the first Sigh effect proved invalid for them.

• Angel explained that God's-eye view could not reveal the puzzles inside the thick wall, and the group approached the sphinx relief.
• Nomephins announced a maze trial in which one Challenger would face traps, guards, random Sigh effects, and a five-drop blood limit that could leave them Locked.
• Angel weighed whether to retreat, but Gray Porcelain volunteered because it had experience clearing its Myriad Phenomena Maze and possessed Danger Sense Talent.
• Angel and Gabriel supported Gray Porcelain, and it accepted the challenge by grasping the metal ring beneath Nomephins' lion claw.
• Nomephins unleashed a black Whirlwind, shrank Gray Porcelain, and swallowed it; Angel guessed the maze lay inside the wall, while God's-eye view revealed nothing that could help.
• As Angel and Gabriel waited and Gabriel chatted with the Rabbit Girl, Nomephins sighed and gave them a doubled-held-blood effect that was invalid because they had not entered the trial.

Angel and Gabriel waited outside Nomephins’s Sighing Wall as Gray Porcelain cleared its maze trial without losing any health. Gray Porcelain explained that Danger Sense had guided it through the maze and revealed that Nomephins had rewarded it with an answer about the sealed being: they would learn its identity after copying all the hidden information.

• Nomephins’s sighs inflicted several effects on Angel and Gabriel, including hearing loss, transformation, blindness, and rigidity, before briefly granting the ability to teleport anywhere in sight.
• Nomephins opened the archway and declared Gray Porcelain had passed the trial with all five drops of health remaining.
• Gray Porcelain joined Angel and Gabriel and explained that it had relied entirely on Danger Sense to navigate the maze, even teleporting repeatedly with its eyes closed.
• Angel realized Gray Porcelain’s instinctive connection to Danger Sense let it process danger at extraordinary speed and clear the maze without mistakes.
• Gray Porcelain said Nomephins had offered one answer as a reward, and that it had asked about the sealed being’s identity.
• Gray Porcelain reported that Nomephins had said they would learn the sealed being’s identity after copying all the hidden information, and Angel reassured it that the answer was useful.

Angel and Gray Porcelain reached the Echo Library’s third floor, where they found a vast void crossed by roads made of flying books. With Book Demons attacking the guardians on the lower floors, Angel left the route-finding to Gray Porcelain after noticing the Observer watching them.

• Angel and his companions cleared the mechanism corridor, found two more Book Demons, and obtained maxims about seeking hidden wisdom and continuing unfinished thoughts.
• Angel used the Location Cursors to narrow the second-floor rift’s location, then left Gabriel to guard it while he and Gray Porcelain headed for the third floor.
• As they climbed a staircase suspended in the void, Angel explained how the void could coexist with the world and how buildings might be constructed in interlayers.
• Gabriel and Rabbit Hole Grand Leader reported that Book Demons had spawned, while Angel and Gray Porcelain reached the third floor’s floating book roads and ruined structures.
• Angel noticed the Observer peering at them and pretended to lack inspiration, leaving Gray Porcelain to guide them using its talent.

Angel passed two Book Sprite trials while Gray Porcelain wrestled with his fear of facing a Book Demon. Gray Porcelain chose to head toward a nearby Book Demon with Angel and asked to fight it just once if it selected him, while Angel secretly attached a Nightmare Illusion Node to his back.

• Gray Porcelain chose the northern sky as their initial direction because he sensed several low-danger responses that might indicate Book Sprites, and Angel went ahead alone to find them.
• While waiting, Gray Porcelain spotted a Book Demon in a distant birdcage-shaped building and recalled Gabriel’s doubts about his ability to face one, deepening his inner conflict.
• Angel returned after passing two Book Sprite trials and used Nightmare Illusion power to calm Gray Porcelain before they chose a route.
• Gray Porcelain chose to travel due east toward the birdcage building and told Angel he would go with him, prepared to face the Book Demon if selected.
• Gray Porcelain asked to fight only once if chosen, and Angel agreed before secretly attaching a Nightmare Illusion Node to Gray Porcelain’s back.

Gray Porcelain defeated a Book Demon by confronting the childhood bully it had once helped bring down, and shared its past with the team. Angel and Gray Porcelain continued across the third floor, where Angel left Gray Porcelain behind to attempt a Book Sprite’s trial.

• Angel told the team that Gray Porcelain had entered a Book Demon’s duel space, and explained that it had chosen to fight because of its sense of responsibility.
• Gray Porcelain defeated the Cuphead inner demon with instinctive barehanded attacks, shattering its porcelain head without using Nightmare Illusion.
• Gray Porcelain revealed that Cuphead had bullied it when it was young, and that it had helped arrange Cuphead’s downfall by leading Wine Cup to the places Cuphead frequented.
• Angel told Gray Porcelain to lead the way again, and they continued along their planned route toward Book Demons with different kinds of record trees.
• After flying across the third floor, Angel spotted a Book Sprite at the center of a path resembling a Ferris wheel and flew off alone to complete its trial.

Angel defeated another Book Demon and led Gray Porcelain to a boundary region after learning that Book Demons and Book Sprites were there. A new aphorism suggested the being they might need to seal was connected to the Abyss, and the chapter left them arriving at a vast cluster of glass towers to search for the remaining clues and rift.

• Angel defeated the sea demon summoned by the Book Demon, entered its birthplace, and obtained its final aphorism as the Book Demon died.
• Angel told Gray Porcelain that Inspiration had revealed both Book Demons and Book Sprites were in the boundary region, then used a god's-eye view to guide them there.
• Gray Porcelain shared the new aphorism, which led the team to wonder whether the Sealed One was an Abyss Demon God; Angel said such beings could die but warned them to retreat if it was a top-tier Demon God.
• Rabbit Girl asked whether Angel had been involved in the Lord of No Flame's death, and Angel neither confirmed nor denied it.
• Angel reassured Gray Porcelain that he would protect it, then brought it to a boundary region filled with towering glass buildings where the final aphorism and rift were located.

Rabbit Girl suspected Angel had been involved in the Lord of No Flame’s fall, while the team discovered all three rifts on the Echo Library’s first-floor border zone and prepared to seek more information before clearing Normal Mode. Angel entered a glass tower to find the final Book Demon and uncovered a hidden-space puzzle that required mixing colors to complete five paintings.

• Rabbit Girl interpreted Angel’s answer about the Lord of No Flame as an indirect admission of involvement, then waited as the team chat resumed.
• Gray Porcelain reported that the team had found all three rifts in one glass tower, and Angel went to search for the final Book Demon while Gray Porcelain kept the rift locked down.
• Gray Porcelain asked whether the team could withdraw if the hidden information confirmed an Abyss Demon God, and Angel and Rabbit Girl agreed to wait for the information revealed after closing the rifts.
• Angel entered a glass tower, pretending to search for the Book Demon for the observer, and found it near the incomplete paintings on the twenty-ninth floor.
• Angel gathered five issues of Harbor Art Appreciation and paints, then realized the hidden-space puzzle required him to mix the colors missing from the five paintings.

Angel opened the final hidden space, defeated a Starfaller summoned by the Book Demon, and learned that the target behind the final aphorism was Cruel Scholar, the Abyss Great Demon God who created Abyss Inscriptionology. The chapter left Angel and the others with the identity and method of the threat they needed to seal.

• Angel restored the missing colors in all five paintings, opening the final hidden space, then went to face the Book Demon.
• The Book Demon summoned a Starry Sky Butterfly using the Starry Sky Book, and Angel defended himself against its swarms of explosive butterflies with the power of the Nightmare Realm.
• Angel restrained and defeated the weakened Starry Sky Butterfly, causing the Book Demon to return to the thirtieth floor and fly toward the hidden space.
• Angel shared the final aphorism in the team chat, prompting Rabbit Hole's Grand Leader to identify its references to Inscription Studies.
• Angel explained that Inscription Studies had been banned because it sheltered interdimensional stowaways and spread its creator's influence across worlds.
• Angel revealed that Inscription Studies was originally called Abyss Inscriptionology and had been created by Cruel Scholar, an Abyss Great Demon God.

Angel explained that modern Inscription Studies had been transformed from the Cruel Scholar’s Abyssal Inscriptions, and the team discussed how they might face the Great Demon God through knowledge and strategy. After they closed the rifts, the group gathered in a plaza where the stage’s observer, Book Fairy, prepared to issue the next mission.

• Angel explained that modern inscriptions drew their status from their makers rather than the Cruel Scholar, while Gray Porcelain feared the team might have to seal the Abyssal Great Demon God.
• Rabbit Hole Grand Commander argued that Echo Library’s knowledge-focused trials suggested the final challenge could be won through technique and wisdom rather than a direct fight.
• Angel returned to the third-floor rift, and he, Gray Porcelain, Gabriel, and Rabbit Girl agreed to close their rifts simultaneously after coordinating a time.
• After the three rifts closed, the group was transported to a plaza of flying books, where Angel recognized that the observer had entered the stage and created the gathering place.
• The team approached a golden-haired creature identified as the observer, and a Wonderland prompt announced that Book Fairy would use temporary authority to issue mission information.

Rabbit Hole met Book Fairy, who warned them that perfect-clear mode would require sealing the Cruel Scholar’s divine thought and could kill them in reality. Angel suspected the Wonderland Authority had a reason to draw Challengers into sealing it, and concluded Rabbit Hole had to achieve a complete seal.

• Book Fairy praised Rabbit Hole’s performance and revealed that another team had found all three rifts but skipped the hidden-information challenges.
• Book Fairy warned Rabbit Hole that perfect-clear mode involved facing the Cruel Scholar and that deaths there would be real.
• Angel identified the Cruel Scholar as the being they had to seal, and Book Fairy confirmed it.
• Book Fairy explained that a partial seal could leave the Cruel Scholar’s divine thought or aura able to escape and attract his attention.
• Angel reasoned that the Wonderland Authority might benefit from the divine thought and had drawn elite Challengers into sealing it.
• Angel concluded Rabbit Hole had to seal the Cruel Scholar’s divine thought with absolute perfection.

Angel and Rabbit Girl convinced their team to continue pursuing Perfect Clear Mode so they could perfectly seal the Cruel Scholar’s divine thought. The Book Fairy began explaining the sealing process, revealing that the divine thought had been given a physical body to contain it and make a precise seal possible.

• Angel speculated that Wonderland Authority had captured the Demon God's divine thought because it expected Challengers to seal it, and Rabbit Girl agreed the threat to Dream Crystal Plain could not be ignored.
• Gray Porcelain questioned whether Wonderland Authority could handle the danger itself, and Rabbit Girl explained that Dream Crystal Plain was not yet a complete world and could not achieve a perfect seal alone.
• Gray Porcelain hesitated over joining the challenge, while Angel agreed the team needed more information about the sealing process before deciding how to proceed.
• Rabbit Girl told the Book Fairy that the team still wanted to challenge Perfect Clear Mode, and the Book Fairy offered to explain the seal while recommending preparations before attempting a perfect one.
• The Book Fairy revealed that the Great Will had given the Cruel Scholar's divine thought a physical body, which served as a prison cage to contain it and make sealing it safer.

The Book Fairy explained how the Rabbit Hole Team could seal the Cruel Scholar’s consciousness, first with nine faith anchors and then with knowledge that would trap its thoughts. The team still had to imprint all nine aphorisms in Perfect Clear Mode and find unfamiliar knowledge the Cruel Scholar could not quickly analyze.

• The Book Fairy explained that the Book Demons’ nine aphorisms were faith anchors created by the Cruel Scholar’s retainers, and that imprinting all nine would activate the sealing ritual array in the All-Knowing Prison Hall.
• Gray Porcelain hoped the team could skip the Book Demon challenges in Perfect Clear Mode, but the Book Fairy said they still had to imprint every aphorism, and the Book Demons might summon different books in each fight.
• The Book Fairy explained that the conventional seal would trap the Cruel Scholar’s body but might let some of its consciousness escape, so the team also needed to trap its thoughts.
• The Book Fairy said the team could seal the Cruel Scholar’s thoughts by offering knowledge it had never encountered and could not analyze quickly, drawing it into studying the knowledge while the ritual array held it in place.
