Investigations

Transport in Jingyu Valley
0/3
Wuling is a land criss-crossed by hills and rivers. How do people travel?
1. Where is the Path Deep in the Grove?
  ...Even people from Hongshan Headquarters can find themselves lost in this place.
2. Bamboo Rafts and Critters
  Pantailbeasts frolic in the woods while fins play in the water. The bamboo raft ride seems to bring one closer to nature.
The Bonekrusher Clan
0/4
Understand the enemy from within, just like the way we learned about ourselves.
1. Gift of Insanity
  They have been driven insane by their thirst for power. Why do they have such fanatical faith in their leader?
2. Means of "Resistance"
  The UWST was obviously taken by surprise. The enemy proved to be skilled in warfare...
Qingbo Stockade
0/4
What happened when they built Qingbo Stockade?
1. Beast Taming Techniques
  Why did beast taming techniques become a thing?
2. Overall Layout
  How did they come up with the layout of Qingbo Stockade?
Marker Stone Area
0/4
What details are involved in the construction of the Marker Stone?
1. Purpose of the Reservoir Station
  Why is the Marker Stone integrated with the Reservoir Station?
2. How is the Marker Stone affected by the water veins?
  The criss-crossing water veins are complex, and many Aggeloi lurk underwater. How do they keep the Marker Stone safe?
Nightmares from the Past
0/4
Evidently, some nightmares from the past have lingered on.
1. Memories of the Crew
  ...The crew mates seem to remember something terrifying.
2. Resistance in the Past
  What is this terrifying entity that forced the crew mates to adopt a near-suicidal means to fight back?
Yanese Ruins of Sword Vault Dale
0/3
Never heard about ruins like these. When was this facility built?
1. Stockaders
  They came prepared. Do they know something? Or did they accidentally stumble into this place?
2. The Treasure
  The priceless treasure, relics... And names that sound quite legendary.
Origins of the Æther Test Site
0/4
The Æther Test Site... For what did they build this for?
1. The Silent Test Site
  What is the Æther Test Site working on?
2. Researchers' Discussions
  ...Don't know what they're researching, but the results don't look very good.
Yinglung Pass
0/4
What did Yinglung Pass face after its completion?
1. Yinglung Special Task Force
  The Yinglungs who gave their lives to the YSTF will only end their vigil at the moment of their deaths.
2. People Outside Yinglung Pass
  What do they know? And what did they do?
Disaster Victims' Attempts of Survival
0/4
How did they survive the exclusion zone when the very land itself was torn apart?
1. Disaster
  Seeing the Blight Miasma for the first time is a most terrifying experience for anyone.
2. Survival
  Despite the horror, none of them gave up the fight for survival.
Operational Model of the Snowy Forest
0/4
What laws did the Snowpriestess create for the Snowy Forest? And what happened to the place after she departed?
1. Environment
  Obviously, extreme environments would require commensurate measures.
2. Change
  Time can bring about all sorts of changes.
Apparition Behavior
0/4
Apparitions seem quite magical. How do they act or behave?
1. Desire for Change
  Their ideas are too wild and crazy.
2. Happy
  Their ideas can be very simple at times.
Yinglung Combat Record
0/7
The lost items we recovered can be used to run an algorithmic simulation of that operation...
1. Investigation: Major Surveillance Op 4
  Endministrator, we requested access to Exclusion Zone (EZ) surveillance logs recorded by the Yinglung Special Task Force (YSTF). The data you have sent perfectly matches the logs of a major surveillance operation conducted two years ago. The operation suffered grievous casualties as none of the five YSTF teams involved in the operation made it to Yinglung Pass alive. We are still looking for leads regarding the coordinates mentioned. All findings shall be synced with you promptly.
2. Investigation: Yinglung Pillar Coordinates Data Log
  We have verified the locations where the Yinglung Pillars have been planted in the Blight Miasma. It is safe to assume that all Yinglung Pillars deep within the Tianshi Pillar R&D Center were planted by the Yinglung Special Task Force (YSTF) teams. However, this area goes far beyond their designated operational zone. Yinglungs are known for their absolute obedience. We suspect that these teams might have made a fleeting discovery significant enough for them to ignore their guiding principles. That being said, our investigation shall continue.
3. Investigation: Team Shore and Team Benefit
  Following comparative analysis, we are certain that Shore was referring to a weapon wielded by Alleikhreos. However, the actual coordinates do not match those provided by you, Endministrator. Nevertheless, the terrain of the exclusion zone may have significantly changed after the landslide. We shall conduct algorithmic simulations based on the data recorded by Shore.
Miscellany and Clever Records
0/7
Stories of unique people and other strange tales that Si has gathered.
1. Food and Farming Are One
  Farming provides the ingredients for cooking. They're definitely very close with each other.
2. Imposing Peak
  When one's mental state is cultivated to the extreme, you will become as detached as they are.
3. Ferrium Trees and Ink Blossoms
  Fire doesn't go with water? From what I see, they're getting along with each other.
4. Blood is Thicker Than Water
  I won't feel lonely as long as you and they are around.
Fangxing Avenue
0/4
How did Fangxing Avenue come into existence?
1. Old Traditions and Novelties
  There are stores selling traditional ware as well as novel gadgets and trendy goods. There is a shop for everyone...
2. Inside and Outside the City
  Everyone, from traveling peddlers to local residents, believes this shopping avenue will only grow.
Aggelos
0/4
Hard headed yet simple enemies.
1. Aggelos Activity
  Local Aggeloid activity was typical and within expected levels until the Incursion of Valley IV.
2. Research by an Amateur Aggelologist
  Most people believe that the Aggeloi will attack any human who enters their detection perimeter. Strangely enough, nobody bothered to study "other things that the Aggeloi might attack"... Is it because the research is unimportant? Who's the one choosing these research topics anyway?
Infra-Station Search and Rescue Brief
0/4
Summary regarding missing evacuees Olga, Rameld, and Pavel from the Infra-Station.
1. Analysis of clues left at the scene
  Based on the clues left at the scene and relevant log records, it appears the three encountered a dangerous situation, with at least one likely sustaining serious injuries. All positioning signals have been lost. While survival remains possible, the absence of further evidence currently hinders organized search efforts.
2. Carried Devices Observation Report
  After detailed observation and analysis, it is concluded that all three individuals are unable to use communication devices for contact. Given the lack of damage to other devices, this appears to be a deliberate disconnection.
3. Analysis Report on Investigation Notes
  Based on Noffman's investigation, the survival probability of the three individuals is extremely low. However, given that no remains have been discovered during the search and there is a lack of direct evidence confirming their deaths, the possibility of their survival cannot be entirely ruled out based on the currently compiled investigative materials.
4. Analysis of Suspect UWST Crew Mate Signals Emitted from Landbreaker-Occupied Territories
  The source location and status of the signals preliminarily indicate that at least one of the missing workers, Olga, remains alive. It is recommended to install signal amplifiers to continue tracking this transmission.
IR: An R&D City
0/13
A collection of past data and records about a certain city swallowed by the Blight Tide. Every finding brings one closer to the truth behind the unknown.
1. Cultural Landscape of the Past
  Records about the daily lives of Suiming City residents...
2. Legacy of the Scientists
  Records that the scientists of Suiming left behind...
3. Warnings of a Major Disaster
  Records about the lead up, the incidence, and the aftermath of a particular disaster...
Murder of a Landbreaker
0/4
Thurston is investigating a mysterious murder ... and hopes to find information that is useful for us.
1. Report: The Hub
  INJURY REPORT: Trauma inflicted by sharp weaponry observed in vulnerable areas across the entire body. To achieve this in a highly intense physical altercation, the murderer must have in-depth knowledge of their moves and behaviors.
2. Report: Aburrey Quarry
  INJURY REPORT: Sudden blow to the throat with rampant Arts surges running throughout the body. Victim was probably attacked during casting. Burn marks on the back. Preliminary deduction is death via electrocution.
3. Report: Origin Lodespring
  INJURY REPORT: There are other dead Landbreakers in the site wearing tokens similar to that worn by "Bloodeye" Sazaro. Perhaps these two findings should be considered as a whole.
4. Report: Power Plateau
  Familiarity leads to trust. Now who would the notorious Landbreaker "Volcano" Chacha trust?
IR: "Tide Flayer" Project
0/3
Wuling Tianshi Mo Hen's "Tide Flayer" Project Research Report
1. Old Project Review Log
  Tianshi Mo once applied for a sizable quantity of Xiranite for the "Tide Flayer" project. However, this application was rejected because the project was deemed too dangerous. The "Tide Flayer" may also be connected to the "lash marks" found near the test fields.
2. A project review log that looks rather dated.
  A Tianshi named Chun He has worked on a project with requirements similar to the "Tide Flayer" project, though its goals are different. We are currently uncertain if the two are connected.
3. Data Log on Mo Hen's Tianshi Apparatus
  After analyzing the leads obtained from the project review logs, we are now certain that Tianshi Mo Hen is the mentor of Tianshi Chun He. Both worked on the "Tide Flayer" project together. Though the project experienced multiple failures, it yielded some results usable for high-density Xiranite structures. However, Tianshi Mo Hen became disheartened after several test runs and abandoned the project. We have no further intel on the whereabouts of Tianshi Chun He.
