Stage / Realm / Level	Chapter	Notes
Eight Trigrams transformation begins	1	An incomplete eight-trigram pattern appears inside Ji’s furnace, matching the diagram on a black furnace he found before transmigrating.
Rotating pattern becomes distinct	2	The eight symbols become clearer, glow faintly, and slowly revolve.
Structure stabilizes	3	The symbols circulate faster as the furnace’s structure grows more stable.
Rotating Eight Trigrams diagram	4	Ji discovers that his furnace has transformed into a rotating diagram, though he does not yet understand its function.
Second-order expansion	87	Ji’s cultivation breakthrough enlarges the interior enough to hold two or three elephants and unlocks refinement of two beasts simultaneously.

Structure and Appearance

• Internal space: A furnace can hold objects far larger than its external location suggests; even a first-order cultivator’s furnace can accommodate an elephant 21.
• Ji Zhixing’s interior: A gray, misty space containing stored equipment and wisps of gene source energy 7 10 11.
• Eight Trigrams pattern: Located on the inner wall, with symbols for Heaven, Earth, Thunder, Wind, Water, Fire, Mountain, and Lake 2 7.
• Refinement light: Ji’s eight symbols emit different-colored light that intertwines around the material being refined 7 10 87.

Functions

Gene Refinement and Fusion

A chosen gene must first be refined in the furnace before it can be incorporated into a gene aperture 1.

• Activation draws a gene sample into the body through an invisible force 7.
• The furnace processes the sample; the gene aperture receives the refined gene during fusion 7.
• Refining beast remains can also produce new gene samples. This is the source of the samples stored in Rain City’s Gene Bank 68.
• Ji obtains more than a dozen glimmers of light after collecting and processing sections of a willow tree, then refines one of its gene samples for his second fusion 68 69.

Beast-Corpse Refinement

A furnace breaks down beast remains and converts them into usable resources. At second order, Ji’s furnace strips away, purifies, and converts flesh, bones, and genetic material under its eight-colored light 87.

Product	Documented Use or Example
Gene Source Stones	The ordinary result of low-order beast refinement; Ji’s classmates repeatedly obtain one stone per beast 21 23.
Gene Potions	Possible rewards include Origin Force and Stone Skin Gene Potions 24 27.
Gene Equipment	Ji obtains a frog pendant, a Blood Crocodile Axe, and a Wolfblade Bracer through refinement 31 87 99.
Exogenous Genes	Can grant additional genetic abilities; Ji obtains one while hunting blood-red spiders 9 79.
Gene Samples	Can be produced from beast remains and used for subsequent fusion 68.
Blood Crystals	Obtained from blood beasts in the Blood Beast Secret Realm 76 87.

• Corpses should be placed in a furnace within a few minutes of death. Delays worsen the results until nothing can be refined from them 20.
• When a potion is produced, the furnace automatically uses the beast’s bones and other tissues to fashion its bottle 24.
• The underlying mechanism of this conversion remains unknown 24.

Equipment Refinement

Refining gene equipment establishes a connection between the cultivator and the item and reveals its information 10 53.

• Technique access: The Black Longstaff supplies the Basic Staff Technique’s training methods and allows its wielder to perform the technique while holding it 10.
• Ability access: Refining the Wind-Splitting Short Saber grants access to its Wind-Splitting ability 53.
• Information retrieval: Ji learns the Chameleon Cloth’s tier, quality, and concealment functions after refinement 99.
• Transformation compatibility: Fully refined equipment can change size with its user. Ji’s Tidehearing Staff enlarges alongside Gigantification 53.
• Independent mastery still matters: Ji initially cannot reproduce the Army-Breaking Staff Technique’s full power with an ordinary staff; he must develop its required will through practice 17 18.

Potion and Resource Processing

The furnace refines substances used for recovery, cultivation, and ability development 37 41 70 85.

• Earth Core Spirit Liquid and Origin Force Gene Potions can be swallowed or refined directly in the furnace, with little difference between the two methods 41.
• Ability-development potions can be processed after ingestion, as Ji does with Stone Bone, Stone Tendon, and Stone Muscle potions 70.
• Blood crystals can strengthen gene abilities, though more than thirty first-order crystals give Ji only modest progress toward super-gigantification 85.
• Five-element potions are refined into power that Ji’s Willow Tree Gene can absorb 95.

Energy and Item Storage

The furnace stores gene source energy, the foundation for using genetic abilities and enhancing strength, speed, and defense 11.

• Equipment can be stored internally and summoned into the cultivator’s hands 10 12.
• Potions and other supplies can also be kept inside 41 70.
• Ji stores a hematite chunk more than two meters across, estimated to weigh over ten thousand jin. Its weight does not hinder his movement, but it occupies well over half his furnace’s space 35.
• Collecting that ore takes several breaths, rather than the near-instant collection shown with beast corpses 23 35.

Ji Zhixing’s Eight Trigrams Furnace

Suspected Origin

Ji notices the furnace’s transformation after recovering his previous-life memories. Its pattern matches the diagram on a palm-sized black furnace he picked up before transmigrating. He suspects that object is connected to both his reincarnation and his altered dantian, but the connection is not confirmed 1.

Perfect Gene Compatibility

Ji’s furnace demonstrably raises compatibility during gene refinement 7 69.

Gene	Initial Compatibility	Final Compatibility	Result
Three-Inch Stone Monkey	72%	100%	Ji immediately hears a clear evolution route and the abilities needed for its first evolution 7.
Willow Tree	73%	100%	Refinement stalls at 97% before Ji overcomes the final barrier and completes fusion 69.

• High compatibility makes ability development easier: Ji needs a first-order, two-star staff technique to awaken Innate Staff Heart, whereas another user might fail even after mastering higher-quality techniques 9.
• Perfect compatibility supplies information, not completed evolution. Ji must still obtain resources, develop the required abilities, and train 9 61.

Unusually Close Equipment Bonds

• Refining the Black Longstaff lets Ji sense every part of the weapon through an exceptionally close connection 10.
• The same sensation of being one with his staff recurs when he refines the Yellowstone Staff 30.
• This refinement bond is distinct from his later Staffsmanship to the Divine ability 88.

Enhanced Refinement Rewards

Ji repeatedly receives richer yields than his companions, although rare rewards remain inconsistent 24 27 77 99.

Material Refined	Ji’s Yield	Comparison or Qualification
First Iron-Feather Mountain Chicken King	Two unusually large Gene Source Stones and one Origin Force Gene Potion	His companions’ ordinary chickens yield one stone each 23 24.
Three beasts personally refined during the first hunt	Two Gene Source Stones per beast	Ordinary cultivators usually receive one 24.
Four Petrified Crabs	Eight Gene Source Stones and one Stone Skin Gene Potion	Ji suspects improved potion odds but conceals the potion 27.
First-order blood beasts	Usually two blood crystals, sometimes three	School information estimates roughly five beasts per blood crystal for ordinary cultivators 76 77 81.
Two second-order blood crocodiles	Four second-order stones, four second-order blood crystals, and a two-star Blood Crocodile Axe	Both corpses are refined simultaneously 87.

Other cultivators also have furnaces with differing reward tendencies, including greater chances of producing potions or equipment. Ji considers his own furnace substantially more abnormal and hides part of its yield to avoid attracting dangerous attention 81.

Unusual Potion Effects

• An Origin Force Gene Potion restores Ji’s depleted source force in only a few minutes, compared with the textbook estimate of ten to twenty minutes 37.
• He develops Stone Skin after thirteen bottles and does not experience the temporary bodily stiffness reported by other users 47.
• He also finds Stone Bone, Stone Tendon, and Stone Muscle potions more effective than online descriptions suggest 70.
• Ji attributes these differences to his furnace, but the precise cause remains his inference 47 70.

Limits and Unresolved Properties

• Mental expenditure: Extended refinement exhausts Ji’s mental power; this occurs with both blood crystals and five-element potions 85 95.
• Finite capacity: Large stored objects can occupy most of the available interior space 35.
• No guaranteed rare rewards: Ji sometimes receives no equipment or potions, despite his enhanced ordinary yields 31 69 99.
• Mixed-species refinement remains unproven: One paired Blood Wolf and iron-armored Blood Beast batch produces only stones and crystals; a second produces a Wolfblade Bracer. No special mixed-species rule is established 98 99.
• Exogenous-gene limits: A cultivator can refine only a limited number of exogenous genes, making compatibility with their existing abilities important 79.
• Aura refinement is proposed, not demonstrated: Xiao Mingyue suggests using the furnace to absorb and refine the aura emitted by a Blood Zhi, but the supplied passage does not establish the outcome 101.
