• The Viscount received a brief phone call that left him visibly frightened, then dismissed Raymond and Lu Yuan without explaining what had happened.

Lu Yuan and the Night Watchers linked the three disappearances to a man using the false name Andre Morris, who sent Lu Yuan a letter referring to the Sea of Knowledge. Lu Yuan went alone to the address in the Outer City, where he found an abandoned bookstore marked with the character “Sea.”

• Ryan presented evidence that the three missing people had received invitations written by the same person, who used the name Andre Morris.
• Helen concluded that a third party had caused the disappearances, since the method resembled the Tower of Erudition’s but the forged identities and personal visits did not fit its motives.

• Lu Yuan decided to meet the sender alone, while Raymond arranged for Karl and Ryan to watch the area and set a half-hour deadline.
• Lu Yuan followed the address to an old bookstore in the Outer City and entered after spotting the final character “Sea” on its sign.

Lu Yuan met the mysterious young man who had summoned him to the bookstore and learned that the man had observed the Ruined House incident. The man left Lu Yuan with an invitation badge and warned him that activating the shell had drawn attention from others across the city.

• Andre Morris warned Lu Yuan that activating the shell had made the city's sealing patterns tremble and that others could sense the disturbance.

He kept Morris's badge, remained a team consultant, and returned to the Alchemy Workshop to work alongside Laurina before an afternoon meeting.

• Lu Yuan examined Morris's badge, gained knowledge from its inscription, and decided to keep it without joining Morris's group.
• Lu Yuan deduced that the Tower of Erudition had moved on from Laurina and might have found a replacement for its plan.
• Lu Yuan told Raymond and Helen about Morris, the badge, and the links between Morris and the three disappearances, but withheld his observations about the Shell and Morris's aura.
• Raymond ordered Lu Yuan to keep the badge safe, remain a team consultant, and watch the Morris lead while preparing to report it at the afternoon meeting.
• Lu Yuan returned to the Alchemy Workshop, drank a Sanity Potion from Laurina, and resumed processing Pharmacognosy materials.

Lu Yuan attended Klaus’s briefing on the inner-city disappearances and learned that Imperial Headquarters had brought the Ascension Society into Bronze City without informing the Night Watchers.

• Klaus briefed Lu Yuan, Raymond, Helen, Karl, and Hogger on the three noble disappearances, the living Eerie entity, and the suspected involvement of Andre Morris and other outside forces.

• Raymond told Lu Yuan to meet at the Branch at eight the next morning to revisit the three disappearance sites, and Lu Yuan requested access to the Archive Room.
• Lu Yuan found four crates from Sandworm Town at the Branch and arranged for them to be sent to the Alchemy Workshop.

Lu Yuan remembered the concealed compartment in Grego’s copper badge and asked Laurina to examine it. She identified the badge as lost memory material and agreed to try opening it once Lu Yuan brought her hemlock extract, while he continued practicing his sanity technique with little progress.

• Lu Yuan found Grego’s copper badge among his belongings and noticed a trace of residual knowledge within it.
• Lu Yuan showed the badge to Laurina, who identified its metal as memory material capable of storing hidden alchemy inscriptions.

• Lu Yuan agreed to fetch the extract during his planned visit to the branch and kept the badge until then.
• Lu Yuan practiced the method in the Knowledge Path Guide, but his Guarding I progress increased only slightly before stopping.

Lu Yuan investigated the North Sea Nautical Records and uncovered the fate of a missing expedition connected to the Tower of Erudition’s Materials College. He left with evidence to pursue Laurina’s vanished alchemists, while questioning whether Morris’s clues were guiding or manipulating him.

• Lu Yuan obtained Hemlock Extract and entered the Night Watchers’ Archive Room with his badge.
• Lu Yuan found the record of a 63-person expedition that discovered an island and underground caves in Imperial Year 1107.

• Lu Yuan found water-damaged fragments suggesting at least two missing expedition members were alchemists from the Tower of Erudition’s Materials College.
• Lu Yuan connected the expedition’s date to Laurina’s vanished acquaintances and wondered whether Morris was helping him or leading him into a trap.

Lu Yuan investigated the mystery surrounding the metal-memory badge and prepared to test whether Laurina’s Trigger Solution could open it. As the solution reacted, he examined supplies from Sandworm Town and continued his guard training, waiting to learn what the badge concealed.

• Lu Yuan collected Hemlock Extract and heard from Karl that searches at the Viscount’s Residence, the Baron’s study, and the Merchants’ Guild had revealed nothing new, while Helen and the captain met Hogger’s people.
• Lu Yuan considered the unanswered questions about the North Sea expedition, the eleven confirmed survivors, and how Grego had obtained the badge, then returned to the Alchemy Workshop with the Hemlock Extract.
• Laurina mixed the Trigger Solution and left it to react for two hours while Lu Yuan wrote down questions about the badge and Morris.
• Lu Yuan opened the remaining crates from Sandworm Town, and Laurina identified the processed Sandworm blood as useful for formulas and the dried gallbladder as a natural purification medium.
• Lu Yuan trained and studied the guard’s Second Order theory while waiting, noting that his progress remained slow at 0.3 a day.

Lu Yuan and Laurina opened Grego’s copper badge and found coordinates and a rough ripple symbol hidden inside, giving Lu Yuan new leads for his investigation. Laurina warned that she might have to leave Bronze City, while the unexplained layer around Lu Yuan’s reflection remained unchanged.

• Lu Yuan and Laurina tested drops of acidic solvent and catalyst until the badge’s inner seam opened.
• Laurina extracted a metal foil containing Empire surveying coordinates and a rough ripple symbol that resembled the design on Lu Yuan’s Shell badge.
• Lu Yuan recorded the coordinates and stored the foil in his notebook, while Laurina said the coordinates were not near Bronze City.
• Laurina told Lu Yuan that the Night Watcher might make her leave once Headquarters arrived and offered to take him with her if danger arose.
• Lu Yuan planned to compare the coordinates in the Archive Room and noticed that the unexplained layer around his reflection had not changed.
