Power Progression

The documented advances primarily restore or strengthen individual facilities. The Corrupted Mycelium reaching Level 1 does not mean the entire Graveyard Demon reaches Level 1 15 31.

Stage / Realm / Level	Chapter	Notes
Barren Graveyard — Level 0, Gray Quality	1	Begins with half its standard area, no initial undead, and disabled movement, Yin-gathering, and Death Devour functions.
Initial undead production	2	A Level 1 Empty Grave converts two goblin corpses into Level 0 skeletons, establishing its first resident squad.
Fence restored; Yin Fire Pit lit	8 9	Salvaged resources repair the perimeter. The fire pit becomes operational but still requires special fuel.
Burial Mound — Level 1	9	Reinforcing a full Level 1 Empty Grave increases its capacity from 10 to 25 undead. The Strange Tree reaches 8% repair.
Corrupted Mycelium — Level 1, Intact	15	Submitting collected mycelium completes Repair Mission: Barren Land, restoring absorption and territorial expansion.
Yin Fire Pile — Level 1, Intact	16 18	Restored production supplies 500 Yin energy every 24 hours.
Grave Head — Level 1	17	A second reinforcement route promotes ten ordinary skeletons to elites, adding 1 Attack, 1 Defense, and 3 Health each.
Autonomous territorial expansion	19 22	Mycelium-covered shopping carts spread corruption beyond the perimeter; surrounding land is absorbed.
Yin Soul Shop — Level 1	28 30 31	Devouring the abandoned gas station unlocks a shop selling items associated with Yin and death energy.
Withered Wood Forest — Level 1; expanded special graves	31	Territory exceeds 600 square meters. New graves produce lumberjack ghouls and bone beasts; the Ghost Tree reaches 51% repair.
Earthbound Vein — one-third repaired	31	Absorbing the Oil Tank Centipede corpse advances movement-system restoration, but mobility remains unavailable.
Further fortification and growth	33 34	Gu Su improves wall fire resistance, increases Yin-energy production, and nourishes the tree. The territory is subsequently described as reaching an acre.
Combat Sentry established	45 46 48	Devouring the half-orc camp creates a warrior-conversion outpost. Skeleton Warriors and Ghoul Warriors subsequently emerge.

Overall Upgrade Requirements

The upgrade panel becomes accessible after Gu Su obtains a suitable core creature corpse 17 18.

Requirement	Documented condition
Territory	866 square meters required; 423/866 recorded when the panel is first checked 18
Building condition	All counted buildings must be intact; initial progress is 4/6. Empty graves do not count toward this requirement 18
Core creature corpse	One Level 1 Core Creature Corpse. The Level 2 Corrupted Jungle Lion King satisfies this requirement and is reserved rather than converted into undead 17 18
Currency and energy	3,000 gold coins and 3,000 Yin energy 18
Construction materials	100 wood, 100 stone, and 100 metal 18
Optional additions	Up to three auxiliary items or special materials 18

Background / History

Before reaching Gu Su, the Graveyard Demon had changed hands multiple times. Its system description identifies it as a deteriorated core with most important functions permanently damaged. Buildings had been dismantled or looted, its territory had shrunk, and its initial undead population was missing 1 18.

Gu Su purchased the Gravekeeper system with three years of savings. The merchant advertised a mobile base with construction, corpse-raising, and troop-training functions, but the delivered graveyard lacked working mobility and several other core features. Entering the novice world leaves Gu Su with a ten-day upgrade quest whose failure penalties include demonic possession, talent weakening, and permanent inability to level up 1.

Gu Su begins its recovery with goblin corpses, blood-soaked soil, and scavenged materials. Finding Corrupted Mycelium in a supermarket’s sealed cold-storage room restores its expansion mechanism. Subsequent hunts and the consumption of nearby structures provide new facilities, specialized undead, and partial repairs to its movement system 2 8 13 15 28 31 46.

Appearance

• Initial grounds: A clearing roughly the size of a basketball court, enclosed by broken, crooked wooden fencing and surrounded by dense gray-white mist 1.
• Central landmarks: A giant dead tree with branches resembling ghost claws, a torn tent draped with dried vines, and an extinguished fire pit encircled by stones 1.
• Burial area: Six empty graves, including three with damaged wooden coffins. Occupied graves close into mounds and produce black tombstones bearing blood-red squad inscriptions 1 2.
• Expanded grounds: Withered trees accumulate behind the graveyard, forming the Withered Wood Forest and influencing nearby graves 22 31.
• Combat Sentry: A square enclosure of sturdy wooden stakes and animal hides, stocked with longswords, round shields, and warhammers 46.

Behavior

The Graveyard Demon displays limited understanding and autonomous responses rather than a developed speaking personality. Its gate opens without external force when Gu Su returns, and it spreads corrupted material beyond its territory while he is away 15 19 29.

Its selection of materials can serve specific repair needs. It absorbs the Oil Tank Centipede corpse because the creature’s former ability to carry a gas station makes it suitable for supporting a mobile graveyard 30 31.

Abilities & Skills

Corpse Conversion and Undead Recovery

Empty graves automatically use Gu Su’s necromancy to turn buried corpses into controllable undead, also increasing his spell proficiency 2 17 40.

• Basic outputs: Level 1 graves produce skeletons; Level 2 graves produce zombies or ghouls; Level 3 graves produce low-tier ghosts 2 17.
• Corpse-dependent variation: Magical potential and other properties of the corpse can affect the resulting undead. A Harpy Leader produces a magic-type skeleton with Lightning Arrow 2 32.
• Reliability: Graveyard-assisted conversion has a better success rate than Gu Su’s battlefield necromancy 6.
• Recovery: Resident undead rest and recover in their graves. An injured skeleton regrows its damaged arm there 8 9.

Grave Reinforcement

Full ordinary graves unlock two distinct reinforcement routes 9.

Route	Effect
Burial Mound	Raises capacity from 10 to 25 without changing undead type; generates a minor leader upon reaching full capacity 9 40
Grave Head / Gravestone	Keeps type and capacity unchanged while promoting residents from ordinary to elite; skeletons gain +1 Attack, +1 Defense, +3 Health 17 31

Corruption, Devouring, and Expansion

The Corrupted Mycelium absorbs compatible items, anomalies, props, and structures associated with death, Yin energy, or undead attributes 15 31.

• Territorial spread: Mycelium-covered shopping carts are ejected beyond the perimeter, leaving corruption trails that infect nearby soil 19.
• Remote consumption: Gu Su transports mycelium or spores to suitable sites, allowing the graveyard to devour structures outside its existing grounds 28 45.
• Facility conversion: Consumed sites offer construction choices. The gas station provides Gas Pump, Warehouse, or Shop; the half-orc camp provides Broadcast Station, Combat Sentry, or Gate Sentry 28 46.
• Material absorption: The mycelium consumes metal shopping carts, leaving rust behind 18.

Specialized Undead Production

The Withered Wood Forest changes two nearby graves into specialized production sites 31.

Output	Yield and use	Limitation
Lumberjack Ghoul	Produces an undead worker with the Lumberjack skill for harvesting wood 31	Combat ability is comparable to an ordinary skeleton 31
Bone Dog	Two per normal corpse; agile patrol creatures with keen smell 31	No Defense; highly vulnerable to attacks 31
White Crow	Three per normal corpse; small flying scouts for locating enemies, resources, and dangers 31	No Attack; cannot fight detected threats 31

• These special graves can become burial mounds but cannot take the elite-upgrade route 31.

Warrior Conversion

The Combat Sentry upgrades existing ordinary or elite undead into equipped warriors 46 48.

Conversion	Cost per unit	Resulting base statistics
Skeleton Warrior	15 Yin energy, 5 gold coins, 1 metal, 1 wood; optional leather 46	Level 0; Attack 5, Defense 4, Health 16 46
Ghoul Warrior	20 Yin energy, 7 gold coins, 2 metal, 1 wood; optional leather 46	Level 0; Attack 5, Defense 8, Health 22 46

Defense and Mobility

• Ghost Tree: Serves as the graveyard’s defense core and responds to Gu Su’s gatekeeping orders 1 9.
• Perimeter: The repaired fence blocks low-level intruders; contaminated engine oil later improves its fire resistance 1 9 33.
• Earthbound Vein: Intended to move the entire graveyard. After its partial repair, it still needs two specters or wandering souls as energy conduits, a mobile power system, and sufficient power. Comparable load-bearing creature corpses offer an alternative repair method 31.

Resource Facilities and Limitations

• Dilapidated Tent — Residence, building core, and access point for status and upgrade panels 1 18 31.
• Yin Fire Pile — Its restored Level 1 form generates 500 Yin energy every 24 hours; Gu Su later enhances production 18 31 33.
• Yin Soul Shop — Offers a daily limit of three items, priced at 2–10 gold coins, mostly carrying Yin- or death-energy attributes 31.
• Withered Wood Forest — Supplies wood and supports lumberjack undead. Its panel lists 1 unit per hour, while the accompanying narration says 1 unit per day 31.
• Water supply — No complete, stable source is established. Gu Su collects limited quantities of dew from the Ghost Tree’s branches 39.

Relationships

• Gu Su — Owner and restorer. He supplies corpses and materials, selects development routes, and relies on the graveyard as his only safe haven 1 9 15 29 46.
• Ghost Tree / Strange Tree — Attached defense core; Gu Su nourishes it with compatible materials to restore its functions 9 16 17 33.
• Bone Ash / Ash — Resident skeleton leader whose scavenging talent supports material collection and waste processing 34 36.
• Coyote — Transport lieutenant whose Swift Sprint talent doubles his squad’s movement speed, supporting supply delivery to the graveyard 41 45 46.
• Gearbone — Repair-and-installation specialist assigned to recover mechanical components and assist with machinery and artillery 47.
