Chapter Summaries

William and Principal Deslin entered Diptus, a plague-ridden port city governed by the Tooth Hall, where William sought a medical examination to learn about the Tooth Fairies' medical technology. The local hospital could not fully examine his unusual body, so William paid a deposit to invite a dentist from the Old World.

• William and Principal Deslin entered Diptus, where the Tooth Fairies welcomed them and offered medical services for payment.
• William asked for a full-body examination, explaining that he wanted to learn about the Tooth Fairies' medicine before the upcoming lunar negotiations.
• At the Tooth Hall's Diptus Branch hospital, William sent Nash and Principal Deslin to wait outside and underwent an examination.
• The hospital's equipment could not fully examine William, so its director offered to request an Old World dentist for at least three thousand coins.
• William paid three thousand coins as a deposit, and the hospital arranged for him and Principal Deslin to stay at a nearby inn while it sought a dentist.

At the Diptus port, William’s request for a physical examination reached the Tooth Mansion, where Deputy Chief Dentist Jessica accepted it after learning he was a human linked to an abyss. Unable to examine him fully before he continued his journey, Jessica agreed to accompany him by ship as he crossed the sea to meet an old friend.

• A Tooth Fairy reported that a mysterious Silver Circle human at the Diptus port had requested a physical examination, and the Tooth Mansion circulated his information to its dentists.
• Jessica reviewed William’s details, accepted the request, and traveled through the root canal passage to Diptus.
• William met Jessica in the examination area, where she recognized the abyss in his abdomen and identified him as its Spokesperson.
• Jessica asked to examine William for a week, but he said he could spare only one day and invited her to travel with him instead.
• Jessica agreed to join William’s voyage and conduct the examination aboard the ship.

William, Deslin, and Dentist Jessica boarded the infected cruise ship Great Gum to cross the sea, with William directing the ship toward an unknown destination. Jessica began preparing to examine William, while Nash was forced to stay in the neighboring suite.

• Deslin advised Nash to disguise himself as a human girl, and Nash praised William’s popularity and status in the circus.
• William introduced Dentist Jessica, who joined the voyage to conduct his week-long physical examination.
• Jessica arranged the Great Gum, an infected cruise ship staffed by Tooth Fairies, and William pointed the crew toward an unspecified direction.
• Deslin took the suite next to William’s and set up a Star Barrier, while Jessica told William to separate Nash before the examination.
• Nash reluctantly moved into the neighboring suite and spent much of his time listening at the wall for sounds from William’s room.

As the Great Gum sailed into an unknown sea, Jessica began a full-body examination of William and discovered that his Lunatic Brain was unusually complete. The examination continued as Nash mistook William’s cries for something else and left the neighboring room in turmoil.

• The Great Gum sailed into the Gray Fog-covered sea, where Whale Eyes watched the ship but did not attack its treated passengers.
• Principal Deslin monitored the surrounding waters with her star chart while Nash secretly listened at the wall between his room and William’s.
• Nash heard William cry out, imagined what was happening, and eventually dug out his frontal lobe to control his emotions before leaving.
• Jessica removed her mask for William and explained that other dentists considered her mouth monstrous, but William told her she was beautiful.
• Jessica examined William by biting his body and discovered that his Lunatic Brain was too complete for her to assess without a craniotomy.
• Jessica bit William’s middle finger, making him cry out and further unsettling Nash in the neighboring room.

William underwent a lengthy examination by Doctor Jessica, who found that his seemingly perfect body was hollow and needed a powerful force to fill and govern it. After a warning about trouble at sea, William saw the Whale Eyes turn hostile, while Fish Source discovered the cruise ship was likely heading toward the mysterious Silver Sea Area.

• Nash woke the next afternoon, found his prefrontal lobe had regenerated to listen through the wall, then removed his brain and soaked it in the bathtub.
• Doctor Jessica examined William and concluded that his body had been transformed with the Ancient Gene but remained empty inside, leaving him vulnerable despite its perfect structure.
• Doctor Jessica advised William that he could strengthen his illnesses over time or seek a powerful force to fill and control the gaps in his body, and proposed examining his Abyssal aspect.
• A transmission warned William that something was strange about the sea, and he saw the Whale Eyes around the ship swollen and bloodshot.
• Fish Source observed the ship's route from the Deep Sea Laboratory and realized it had a greater than sixty-five percent chance of reaching the Silver Sea Area, so he personally controlled the Whale Eyes around it.

Deslin protected The Great Gum from the Whale Eyes, but the effort left her injured. After the threat passed, William, Jessica the Dentist, Deslin, and Nash shared a meal, and Deslin invited Jessica to stay in her room.

• Whale Eyes charged the cruise ship, but Deslin used spatial power to let them pass through the hull and later stop their attacks.
• Fish Source. Nashatar recognized a Stargazer aboard the ship and sent a sea folk envoy to negotiate with its passengers.
• William entered Deslin’s room through her spatial barrier, saw her injury, and was kicked out after she warned him not to barge in again.
• Deslin reassured Jessica the Dentist that she was welcome to eat with them, and Jessica removed her mask and revealed her face.
• Deslin invited Jessica and William to share her room, while Nash was left alone in the flooded corridor after the door closed.

William underwent an examination of his Abyss by Jessica, then accidentally triggered a powerful Abyss Inversion aboard the ship. After Deslin shared her stardust with him for a dream, she was trapped in a nightmare until Jessica woke her.

• Jessica examined William’s Abyss and nearly suffered infection, but concluded that his many internal diseases were too shallow to complete his physical framework.
• William tried Abyss Inversion in the bathtub, causing the ship and surrounding sea to distort before he stopped.
• Deslin gave William ten drops of her celestial blood to create a starry bath and invited him to enter a shared dream.
• Deslin awoke in a flooded cabin and found Jessica and William missing, then encountered a grotesque woman whose mouth held Deslin’s own head.
• Teeth tore apart the nightmare, and Deslin woke in Jessica’s arms.

A Deep Sea Patient named Kexia came aboard to deliver Fish Source’s request for William’s group to investigate the sea area where the ocean was turning silver. William agreed to the mission but sent Kexia away at Jessica’s insistence, and she secretly followed the ship toward the Silver Sea Area.

• Jessica the Dentist and Deslin located the Deep Sea Patient who had infiltrated Deslin’s dream and found Kexia waiting outside the bedroom.
• Kexia entered the bedroom and said she had come on Fish Source’s orders to deliver important information.
• Nash attacked Kexia, healed from her counterattack, and warned her not to disturb William before William emerged and ordered him to stand down.
• Kexia asked William’s group to investigate the silver sea and, if possible, kill the entity responsible for turning the ocean silver; William agreed to the task.
• When Kexia objected that Jessica wanted her gone, William told her to leave, and she secretly followed the cruise ship toward the Silver Sea Area.

William’s ship sailed toward the Silver Sea after Fish Source tasked them with investigating it, and Jessica agreed to join the crew after learning that William’s friend was the source of Moon Disease and ran a lunar clinic. After ten days, the ship reached the silver waters, where William prepared to conceal his identity and found no moon in the sky.

• William explained that the Silver Sea was connected to his friend, the origin of Moon Disease, and persuaded Jessica to join the journey by mentioning the friend’s clinic.
• Deslin recognized that William had deliberately drawn Jessica into the group and urged her to stay close once they reached the Silver Sea.
• William admitted to Deslin that he had maneuvered Jessica into joining because he feared the mission would be dangerous and wanted to improve their chances of survival.
• William arranged for Yi Chen to take over his body and erase traces of his identity when they entered the Silver Sea, so they could investigate before trying to reach the moon.
• After ten days, the captain reached the Silver Sea, where the crew stopped the ship and William saw no moon overhead.

William and his companions entered the dangerous Silver Sea Area to investigate the Moonification Disease signal and confront the threat tied to Lorien. They became trapped in a True Illusion and discovered an uncharted island, while Kexia followed them after swallowing Fish Source's Origin Scales.

• Captain Yevhen Obestein glimpsed an underwater monster through his telescope, tore out his own eye, and began suffering silver seawater leaking from his ears and brain.
• William stabilized Yevhen and learned that the Silver Sea Area contained a monster whose appearance threatened to shatter the captain's mind.
• William and Principal Deslin decided to enter the area, and William concealed himself behind the Abyss Mask as Yi while Jessica the Dentist and Deslin joined him aboard a starlit yacht.
• The yacht crossed into the Silver Sea, where the group became trapped in a True Illusion and Deslin kept their vessel hidden in the astral interlayer.
• Yi, Jessica, and Deslin spotted an enormous island missing from the organization's map as they traveled deeper into the Silver Sea Area.
• Kexia followed the yacht into the Silver Sea Area after swallowing the Origin Scales given to her by Fish Source.

Yi Chen and his companions landed on an island in the Silver Sea, where their boat vanished and a faceless girl revealed herself to be a bizarre creature. After Yi Chen beheaded her, her monstrous form emerged, and a huge transparent sea creature swallowed the heads that escaped into the water.

• Yi Chen and his companions stepped onto the island, and Deslin realized they had crossed into a deeper layer of the illusion when their boat disappeared.
• Yi Chen approached the girl playing in the sand while his companions stayed back, and he beheaded her after her moon-like face triggered a strange illusion.
• Dead fish poured from the girl's neck and revealed a huge silver sunflower structure covered in shaved heads.
• The heads detached from the sunflower and crawled into the Silver Sea, where a hundred-meter transparent creature appeared and swallowed them.

Yi Chen entered an island where chaos distorted reality, and he encountered monstrous versions of Principal Deslin and Jessica the Dentist before continuing toward the forest alone. A shift in perspective revealed that the Yi Chen on the beach had been behaving violently and was dismembered, while Deslin and Jessica agreed to stay together and kill each other if either seemed altered.

• Jessica the Dentist sampled the silver sunflower, but her bacteriophages failed to destroy its tissue and the solution began growing strands that attacked her.
• Principal Deslin explained that Galon’s connection to an Unknown World may have been fused with the moon’s influence, and she proposed searching the island for Moon Scar.
• Jessica and Deslin argued, then transformed into a fused body and advanced on Yi Chen, who decapitated them and watched their corpse become a stone sculpture.
• Yi Chen found a silver tooth embedded in his wrist, severed his arm when it proved connected to Black Hair-like nerves, and walked alone toward the forest.
• The perspective shifted to the beach, where another Yi Chen had attacked Jessica and been dismembered; Deslin and Jessica vowed to stay together and kill each other if either seemed wrong.

Yi Chen explored the Silver Sea island as its chaos warped his surroundings and eventually his clothing, while William urged him to surrender control. After William’s insults forced their bodies apart, Yi Chen decapitated him, but both appeared to die, and puppets carried their remains deeper into the island.

• William and Nash hid inside the treasure chest in the Memory Palace aquarium while Yi Chen explored the island alone.
• Yi Chen found that his Gentleman's Attire had become a monster and tore it off before rejecting William’s demand to take over.
• William’s voice continued through the sealed Mad Brain, and his insults split his main body from Yi Chen’s Second Body.
• William shot at Yi Chen, but Yi Chen blocked the bullets, closed in, and decapitated him with the hand axe.
• Yi Chen also began to die, and two wooden mannequins carried away his body and head toward the island’s depths.

Deslin and Jessica the Dentist searched the island for William, and Jessica used a vaccine to suppress the island’s illusions. At the moon crater, Jessica succumbed to the chaos and Deslin entered the passage alone, unable to tell truth from falsehood.

• Deslin killed the apparent Jessica the Dentist after rejecting her advances, then nearly fell for a lighthouse illusion of her family before the real Jessica injected her with a vaccine.
• Jessica explained that she had recognized the fakes replacing Deslin and William, killed them, and made the vaccine using them as samples.
• Deslin sensed William’s location from the lighthouse, and she and Jessica crossed the island to a crater at its center.
• Deslin realized the island was the exposed tip of the Moon in Water, submerged beneath the Silver Sea, and followed William’s aura toward a passage in the crater.
• Jessica withdrew from Deslin and revealed herself as a lunar face; the chaos overwhelmed the vaccine, and Deslin walked into the passage alone.
• Jessica later regained her senses near the crater and discovered that Deslin had vanished.

Jessica entered the depths of the Moon Core to rescue Deslin and confronted the being ruling the moon. Calling itself the Moon God, it announced that it would execute Mr. Yi and made Jessica a witness.

• Jessica prepared to descend by reshaping her skull with teeth and using Oral Medicine to suppress the chaos, then entered the moon pit with vaccines dripping into her arm.
• Jessica was overwhelmed by the passage’s whispers and arrived at a temple in the Moon Core, where she resisted the chaos by knocking out her original teeth as she walked.
• Jessica found Deslin kneeling before the throne and asked the ruler if it was Moonscar Lorien.
• The ruler declared itself the Moon God, praised Jessica, and offered her a place under its command after she witnessed a procedure.
• The Moon God lowered the stitched Mr. Yi into the temple and declared that it would execute him as an unworthy counterpart to William.

Lorien beheaded Yi Chen repeatedly in a false world, but Yi Chen revived each time and broke the illusion. Yi Chen, Jessica, and the Principal awoke in a clinic laboratory, where Lorien acknowledged Yi Chen’s ability to escape the Brain in a Vat.

• Lorien beheaded Yi Chen, believing the moonlight had permanently marked him for death.
• Yi Chen’s head and body repeatedly rejoined as the dead he had killed emerged from black liquid to restore him.
• Yi Chen explained that repeated death suited him and that Lorien’s chaotic ability had nearly trapped him in a false world.
• Yi Chen struck Lorien’s blood-moon skull with an axe, shattering the false world.
• Yi Chen, Jessica, and the Principal awoke in a silver-liquid bathtub in an underground clinic laboratory, connected to a device containing a prismatic brain.
• Lorien told Yi Chen he was the first person to escape the Brain in a Vat through his own ability.

William and Principal Deslin confronted Lorien in his underground laboratory, where Lorien revealed that he had fused with Galon and created the Dreamscape. The group agreed to stay on the island, but William’s attempt to touch Lorien ended with his palm torn apart by a moonlight barrier.

• The Female Doctor deflected Yi Chen’s axe, and Yi Chen yielded control of the body to William.
• Principal Deslin learned that the Brain in a Vat was an illusion core, not Galon’s brain.
• Lorien revealed that he had fused with Galon, whose restored ability to sleep and freedom had made the arrangement welcome.
• William apologized and offered Kexia as a gift, while defending Jessica and explaining that she had come as his friend.
• Lorien accepted Kexia and invited William, Principal Deslin, and the others to stay on the island; he and William discussed the silver ocean and the Fish Source.
• William offered to help Lorien kill the Fish Source, then tried to touch him, but a moonlight barrier shattered and tore apart William’s palm.

William hosted a banquet on the Moon and used his Instant Noodles to improve Fana’s stability and impress Lorien. He then proposed that Lorien temporarily join the Fear Circus as his partner, leaving Lorien suspicious that William’s visit had been intended to forge a connection between the Moon and the circus.

• Deslin and Jessica toured Lorien’s clinic, where Lorien explained that its nurses had evolved from contaminated Medical Equipment and would soon undergo Chaotic Modification.
• Lorien gave William, Deslin, and Jessica Moon Marks and arranged a banquet, while William volunteered to prepare the food.
• At the beach banquet, William served Instant Noodles that caused powerful Deep Sea effects, and Fana’s stability improved after she ate them.
• Lorien asked William to supply the noodles in bulk, but William said the circus’s rules prevented him from providing them directly.
• William proposed that Lorien join his circus department temporarily as an equal partner so he could prepare more noodles for the Moon.
• Lorien asked whether William had planned his visit to connect the Moon with the circus, and William left the choice to him.

Lorien and William negotiated a deal that would send Lorien to perform with the Fear Circus, and they agreed to settle it with a fight between their subordinates. Fana and Nash began battling on the beach, and the fight escalated as Nash drew his weapon.

• Lorien offered to join William's department as an outside expert if William's subordinate defeated Fana, but demanded five-digit quantities of Instant Noodles if William lost.
• William sent Mahath J. Nash, his new deputy head, to fight Fana, while Lorien authorized Fana to release a chaotic shackle within her body.
• Fana attacked Nash with powerful kicks, but he regenerated rapidly and taunted her.
• Fana transformed into Forced Infusion—Fana Oligovich (Crimson Cross Society) and attacked Nash with needle-tipped infusion tubes.
• Nash severed many of Fana's tubes with the Hundred-Headed Hunter and warned that he might accidentally kill her.

Nash fought Doctor Fana in a spar, but her Forced Infusion overwhelmed his body before he stopped his killing strike in obedience to William's order. Lorien declared Fana the winner and agreed to join the circus after finishing his Silver Sea work; William then asked to speak with the deep-sea gift before reporting back to the Fish Source.

• Nash revealed the Hundred-Headed Hunter dagger, and William learned from Yi Chen that Nash's fragmented killing intent came from carrying out others' orders.
• Fana transformed by injecting the Blood Cross into her brain and used Forced Infusion to inflict severe allergic reactions on Nash.
• Nash endured the infusion and stopped his blade at Fana's forehead, refusing to kill her despite his condition.
• Lorien ended the spar, declared Fana the winner, and promised to bring the moon to the circus after completing his Silver Sea work.
• Nash returned to the feast after expelling much of the chaotic substance through self-mutilation and regeneration, and William gave him Instant Noodles.
• William asked Lorien for permission to question the deep-sea gift, and Lorien warned him not to get handsy.
