Chapter Summaries

Yang Yi tested trophies on the Execution Rack and discovered that a Light Fairy Shard granted the Nightmare Star a temporary skill that summoned light from the sky. He used the light to inspect the ruined lighthouse at the Shelter’s intersection, finding extensive damage and a collapsed searchlight level.

• Yang Yi returned to the Nightmare Star with Su Na, used a Light Container to clear darkness from the ship, and tested several trophies on the Execution Rack.
• Yang Yi displayed a House Mouse head and gained the skill Summon Skeleton Rat, then tested bones and limbs that added small amounts of hull durability.
• Yang Yi hung a Light Fairy Shard on the Execution Rack, triggering the single-use Steal Light skill and illuminating the Nightmare Star and its surroundings for ten minutes.
• Yang Yi told Su Na about the trophy effects and steered the Nightmare Star toward the Shelter’s intersection to inspect the lighthouse.
• Yang Yi saw that the lighthouse had numerous breaches, its Captain’s Quarters had been torn open, and its searchlight level had collapsed.

Yang Yi spent the night aboard the Nightmare Star, catching up on World Chat and eating from his dwindling food supplies. He visited Su Na’s laboratory, where she studied House Mice and prepared a potentially explosive new Spirit Potion using his blood.

• Yang Yi read World Chat reports about a player robbing a Golden Commerce Guild ship and another publishing a World Map, then sent Song Yingwen information about House Mice, black shadows, and Light Containers.
• Yang Yi sold his Engineering Gloves for 7,999 Conch Coins, ate spoiled Super Delicious Cake, and cooked Black-Skinned Potatoes with salted Dried Fish.
• Su Na kept two House Mice alive inside Pale Worm tentacles after another mouse exposed to black fog aged and died.
• Yang Yi brought Su Na potato and salted fish soup and asked about her new Spirit Potion, which she planned to split into two doses because its ingredients exploded when mixed.
• Su Na drew nearly half a jin of Yang Yi’s blood so she could produce a sample of the potion.

Yang Yi climbed the damaged lighthouse in the abandoned Shelter, hoping to uncover clues about what had happened there. He found a message directing him to Laboratory 3’s medical area in Area C, and planned to investigate that section next.

• Yang Yi left the Nightmare Star under the Penitent Armor’s guard and entered the Shelter through a breach.
• Yang Yi found severe battle damage inside but no player corpses, then abandoned the blocked stairwell and climbed the lighthouse in Wolf Transformation.
• Yang Yi reached the looted captain’s quarters and discovered a message scratched into a metal desk: “Laboratory 3, medical area, Area C.”
• Yang Yi checked the Shelter’s structural diagram, learned Area C was devoted to technology and included a large medical section, and photographed the message.
• Yang Yi found part of a similar message on a piece of wall and realized other clues might have been taken or destroyed.

Yang Yi recovered the Bone Spear from the ruins and discovered that it grew bone barbs and could mutate a target’s bones. He brought the strange, incomplete skeleton back for Su Na to examine.

• Yang Yi caught a live Long-Legged Sardine by hanging a Light Container over the ship’s side and discussed his theory that a rebellion had destroyed the Shelter’s Captain’s Quarters with Su Na.
• After resting, Yang Yi sailed the Nightmare Star to the previous port, where Su Na gave him two bottles of her experimental Spirit Potion.
• Yang Yi sent the Penitent Armor down the elevator shaft and found no House Mice in the scorched ruins.
• At the end of the corridor, Yang Yi found the unidentified creature reduced to a skeleton and observed that the Bone Spear had grown barbs and mutated nearby bones.
• Yang Yi freed the Bone Spear and noticed that the skeleton lacked ribs and a lower jaw, so he prepared to bring it to Su Na.

Yang Yi and Su Na examined the remains of a Rat Slave and discussed how House Mice might have contributed to the Shelter’s fall. They sailed to Area C and found a warning painted on its damaged gate, which Yang Yi sent the Penitent Armor through.

• Yang Yi identified the bones as belonging to a player named Gu Ze, a Rat Slave parasitized by House Mice, and Su Na reconstructed the skeleton to study its deformities.
• Su Na suggested collecting House Mouse pelts for armor and trade, while Yang Yi stored the bones for a future gacha exchange.
• Yang Yi asked whether the mice had caused the Shelter to fall, and Su Na said she needed a living specimen to examine their toxins.
• Yang Yi and Su Na sailed to Area C, where Yang Yi used the Eye of Greed Telescope but found no valuable targets.
• At Area C’s gate, Yang Yi photographed a skull-and-cross warning and directed the Penitent Armor inside.

Yang Yi and Su Na reached the sealed entrance to Medical Area Laboratory No. 3, where a transparent wall and laser guns guarded the way. After the Penitent Armor failed to break through, Su Na used her magic to destroy one of the guns, leaving them poised to continue their attempt to enter.

• Yang Yi sent the Penitent Armor and Skeleton Rat down to Underwater Level Three, where an intact disinfection chamber and warning sign marked the laboratory entrance.
• The chamber's security system activated, and its laser guns burned the Skeleton Rat to ash and damaged the Penitent Armor.
• Yang Yi tried to smash through the transparent wall, but it held firm and broke his Crystal Greatsword before he withdrew the damaged armor.
• Yang Yi told Su Na they would try the Flintlock's Roaring Mode or find another route, but Su Na said she had a way.
• Su Na entered the chamber behind the Penitent Armor, raised her Force Field Deflection Great Shield, and bent one laser gun until it sparked and broke.

Yang Yi and Su Na defeated the beam guns, discovered a strange robot behind the security door, and found that it recognized Su Na as a doctor. Xiaoji opened the transparent wall and offered to capture Yang Yi, whom it mistook for an escaped test subject.

• Su Na used Curling Touch to destroy both beam guns while her force field deflected their shots.
• Yang Yi noticed the room was unnaturally clean and warned Su Na that something else was inside.
• A damaged six-armed robot emerged from the security door and mistook Su Na for a doctor.
• Yang Yi tried to pass himself off as the Shelter First Mate, but the robot ignored him as an escaped test subject.
• Su Na ordered the robot to open the Protective Wall, and Xiaoji raised it.
• Xiaoji offered to subdue and cage Yang Yi at Su Na's command.

Yang Yi and Su Na explored the Laboratory, where Xiaoji Robot guarded the facility and its restricted area. Su Na found Dr. Wei’s remains and learned that she had been parasitized by a House Mouse, while a photograph suggested Dr. Wei had been close to the ship’s captain.

• Yang Yi and Su Na entered the Laboratory with Xiaoji Robot and found that darkness had rusted much of the equipment.
• Yang Yi discovered a damaged ceiling opening and concluded that intruders had fought Xiaoji Robot and likely suffered heavy losses.
• Xiaoji Robot said Dr. Wei had stayed in the restricted room for over 1,745,000 days, and Su Na entered alone while Yang Yi remained outside.
• Su Na passed rows of jars containing skeletal specimens and found a desiccated mutant seated at a desk in the innermost room.
• Su Na identified the corpse as Wei Qian, a human parasitized by a House Mouse, and found a photograph of her with a man who appeared to be the ship’s captain.

Su Na explored Wei Qian’s laboratory and uncovered records about the House Mice, their parasitic pheromone, and a potion that could kill them. She left with evidence to study and the possibility of reproducing the Rat Killer, while Yang Yi hoped to use it against the rats.

• Su Na examined the tablet’s chat messages and learned that Dijie had warned Wei Qian to escape to Area C, while Wei Qian’s unsent reply suggested she died soon afterward.
• Su Na identified an empty bottle as Rat Killer, a potion made by Wei Qian that killed rats when they smelled it, and sent its information to Yang Yi.
• Yang Yi asked Su Na to reproduce the potion so he could poison the rats, and Su Na said she should be able to.
• Su Na reviewed Wei Qian’s experiments and learned that House Mice could parasitize many creatures and manipulate hosts with a powerful love pheromone.
• Su Na photographed the laboratory records for later study and considered the unfinished Love Potion, but preferred Yang Yi as he was.

Su Na passed Wei Qian’s test and learned how to access more of her research, while Yang Yi discovered the Shelter’s food printer. The chapter ended with Su Na warning Yang Yi that his meal had been made mostly from rats.

• Su Na found an anonymous A-rank access card and was sealed inside the laboratory, where Wei Qian’s hologram gave her a timed test.
• Su Na scored one hundred on the test, and Wei Qian identified her as a witch and explained how to access research stored in the robot.
• Wei Qian warned Su Na that traitors might be among the players and told her to watch out for Beautiful Dream.
• Yang Yi befriended the Xiaoji Robot and used the food printer to produce dishes and drinks.
• Su Na asked what the food was made from, and the Xiaoji Robot revealed that it was mostly rats, upsetting Yang Yi.

Yang Yi and Su Na gathered equipment and robots from the Shelter as they prepared to make a rat killer and deal with the House Mice. After a damaged data transfer revealed that Xiaoji had changed far beyond its original programming, Su Na suspected the robot had developed a soul.

• Yang Yi learned that the House Mice had overrun the Shelter and that rats still nested in the General Warehouse, then took ten roast chickens from the food printer.
• Su Na took over Dr. Wei’s work, and Xiaoji recognized her as its new master while answering Yang Yi’s questions about the Shelter’s past population and surviving robots.
• Yang Yi summoned three damaged robots, named them Little One, Xiao Er, and Little Three, and brought them with Xiaoji back to the Nightmare Star.
• Su Na connected Xiaoji to a Tablet Computer to retrieve Wei Qian’s research, but the transfer stopped at 42% because its stored data was damaged.
• Su Na found a broken prototype Love Potion inside Xiaoji and learned that the robot had originally been designated Eight with low-level artificial intelligence.
• Su Na concluded that the potion might have contributed to Xiaoji’s unusual intelligence and believed it might have developed a soul.

Yang Yi marked the robots, prepared for a rat hunt, and discovered that his potted plant had grown into a strange fishlike sapling. He left Xiao Er Robot to guard it while it continued to mature.

• Yang Yi marked Xiaoji Robot with an eyepatch and gave it worm grease, then learned from Su Na that the rat killer would take two to three days to make and required House Mice for mass production.
• Yang Yi sailed the Nightmare Star back to the original port and found that a Rat Slave skeleton granted the ship the ability to summon ten Skeleton Rats.
• Yang Yi used the skeleton in the Gacha Machine, received House Mouse Gloves, and gave them to Su Na before repairing his crystal greatsword.
• Yang Yi found a purple, fish-shaped plant growing in the pot and learned from Su Na that it needed two more days to mature.
• Yang Yi ordered Xiaoji Robot to guard the plant, but Xiaoji delegated the task to Xiao Er Robot.

Su Na recovered Wei Qian’s research data while Yang Yi prepared to search for Rat Slaves. At the port entrance, Yang Yi discovered that House Mice were hiding in the ventilation openings and warned Su Na before moving inside with two robots.

• Su Na organized Wei Qian’s damaged research records and learned about his Magic Stone energy technology.
• Xiaoji told Su Na that Yang Yi had recorded a warning about her long hours, and she went to the deck while Yang Yi pretended to sleep.
• Yang Yi reviewed the robot manual, prepared supplies and weapons, and set out with Little One and Number Three to catch Rat Slaves.
• Yang Yi smelled House Mice near the port entrance and found circular ventilation openings where the rats could hide.
• Yang Yi warned Su Na that the rats might be watching and preparing an ambush, then entered the port with the two robots.

Yang Yi fought a House Mice ambush on the third floor and defeated a fused monster made from parasitized crew members. After learning the rat nest could be used in the Monster Gacha Machine, he began dragging it back while Su Na reported that the Nightmare Star had also been attacked.

• Yang Yi entered the third-floor corridor in Werewolf Form and was struck by a powerful arm reaching from the elevator shaft.
• A Conjoined Limb Spider emerged, repaired its limbs with Grafting Surgery, and sent House Mice to attack Yang Yi and the robots Little One and Little Three.
• Yang Yi removed the monster’s enhanced arm and set himself on fire to keep the little House Mice from parasitizing him.
• Yang Yi dismantled the Conjoined Limb Spider and subdued the giant House Mouse in its chest, identifying the creature as a Conjoined Rat Nest.
• Yang Yi sent the rat nest’s information to Su Na, who told him to bring it back and reported that the Nightmare Star had also come under attack.
• Yang Yi stored the monster’s limbs and dragged the rat nest toward the dock as Little One and Little Three fought the rat swarm.

Yang Yi searched the conjoined monster and recovered a pocket dimension bag, a laser pistol, and other supplies before fighting his way through swarms of House Mice toward the Nightmare Star. A Rat Slave ambush knocked down his robots and forced him to use Healing of the Flame, but he rose in the Penitent Armor’s helmet and prepared to shoot back.

• Yang Yi found a Dirty Grafting Surgery Kit and a Pocket Dimension Bag hidden in the conjoined monster’s rat-filled abdomen.
• Yang Yi recovered supplies, 3,327 Conch Coins, a Giant Clawed Shrimp’s Right Claw, and an Old Laser Pistol from the bag.
• Yang Yi fought through the House Mice with his two robots and contacted Su Na, who warned him that the rats were increasing and could swim.
• Rat Slaves ambushed Yang Yi with beams and gunfire, shattering his Crystal Great Shield and severely damaging both robots.
• Yang Yi used Healing of the Flame, put on the Penitent Armor’s helmet, and readied his large-caliber Flintlock against the Rat Slaves.

Yang Yi escaped the Rat Slaves’ ambush at the Shelter and fought his way back to the Nightmare Star with damaged robots and living captives. After sailing away from the port, he and Su Na assessed the captured Rat Slaves and the robots’ condition.

• Yang Yi killed the first Rat Slave squad, then dragged Little One, the Conjoined Rat Nest, and several Rat Slaves through the port while a second squad attacked him.
• Yang Yi destroyed the pursuing squad and part of the passage with the Flintlock’s roaring mode, then reached the docks as rats swarmed the Nightmare Star.
• Su Na prepared to sail, and Yang Yi threw Little One and the captives onto the deck before joining her aboard the ship.
• Yang Yi and Su Na escaped the rats, stopped five nautical miles from the Shelter, and discussed the Rat Slaves’ weapons and ambush.
• Su Na placed the surviving Rat Slave and Conjoined Rat Nest in the Witch Laboratory, then agreed to try repairing Little One and Little Three.

After the battle, Yang Yi examined his spoils and used a Ratman Hero Cape to disguise himself as Mouse Man, giving him a possible way to infiltrate the Rat Nest. He then crafted a crude rat-pelt cape that offered some protection from the darkness and planned to sell it.

• Yang Yi tested an Old Laser Rifle by shooting a Human-Head Octopus, angering the Old Captain, who went on strike for a day.
• Yang Yi tested a Rat Slave trophy, then fed three Rat Slave corpses into the Monster Gacha Machine and obtained a Ratman Hero Cape, an Inscribed Stone, and ten Magic Stones.
• Yang Yi activated the cape and discovered it transformed him into Mouse Man and let him speak Rat Language; Su Na suggested using the disguise to sneak into the Rat Nest and poison the rats.
• Yang Yi canceled the transformation and spent six hours sewing a poor imitation of the cape from House Mouse pelts.
• The system identified the imitation as ugly but durable and somewhat protective against the darkness, and Yang Yi decided it could sell well.

Yang Yi crafted imitation Ratman Hero Capes, upgraded a Shoulder Bag into a Pocket Dimension Bag for Su Na, and sold his goods while sharing advice about surviving the Sea of No Light. He ended the chapter monitoring player news and saw a warning that exposure could jump from 90% to 100%, causing someone to disappear.

• Yang Yi planned to make 26 imitation Ratman Hero Capes and learned from Su Na that mass production of the Rat Killer would take several more days.
• Yang Yi upgraded the Shoulder Bag into a six-cubic-meter Pocket Dimension Bag and sent it to Su Na with Xiaoji Robot.
• Yang Yi crafted more capes, checked his condition, and rested before trading opened at 23:00.
• Yang Yi sold his laser pistol, laser rifle, and all 26 imitation Ratman Hero Capes, using the name One-Eye to attract buyers.
• Yang Yi shared detailed information about the Sea of No Light, and players responded by asking questions and buying capes.
• Yang Yi read a player's warning that Stealth Capsule exposure could jump from 90% to 100%, making a person disappear.

Yang Yi realized the Sea of Miracles’ map might be changing, then fell into a lucid nightmare as Captain Dijie, a vampire aboard the Shelter. He killed First Mate Holence and began convincing a frightened guard that Holence had been parasitized by a rat.

• Yang Yi noticed the World Map showed neither special seas nor Dabar and suspected the Sea of Miracles was shrinking.
• He weighed keeping the captured Shelter as an outpost against dismantling it, and decided to postpone the choice until after clearing the rat nest.
• Yang Yi awoke amid gunfire in the body of Captain Dijie, identified Holence as an unfamiliar man, and killed him with a Beam Cannon.
• He examined Dijie’s vampire status and recognized that he was lucid inside a dream, retaining his talents.
• A guard entered, accused Yang Yi of being parasitized, and grew suspicious after seeing Holence’s headless body.
• Yang Yi claimed a rat had parasitized Holence and turned over the corpse to show the guard.

Yang Yi discovered that First Mate Holence was infected with House Mice and learned the defenders were vastly outnumbered, so he set out to obtain Rat Killer and change the battle’s outcome. He left Liu Dong in charge of the defensive line and flew toward Area C to find Wei Qian.

• Yang Yi found House Mice parasitizing Holence and killed them, then discovered a silver dagger hidden in Holence’s sleeve.
• Liu Dong reported that only 207 guard fighters and 602 civilians remained against more than 70,000 Rat Slaves.
• Yang Yi appointed Liu Dong first mate and ordered him to hold the defensive line while Yang Yi pursued a way to defeat the rats.
• Yang Yi drained Holence’s blood, restored his Qi and Blood, and adapted to his Higher Vampire form.
• Yang Yi surveyed the battle, flew out of the tower, and headed for Area C to find Wei Qian and obtain Rat Killer.
