History
Dao Cultivation first appears when Jiang Yuechu kills the dying Pei Changqing and receives 20 years from him. She burns the entire amount to survive against Tiger Mountain God, gaining an immediate influx of blade knowledge and physical strength. She later recognizes that direct expenditure only provides a temporary boost and is comparatively inefficient. 2
Its long-term value becomes clear after Jiang Yuechu records Tiger Mountain God as a Shadow Copy. The recording grants her Fierce Tiger Quickblade, while future investment into the recorded demon raises its progress and unlocks further talents, divine abilities, and demonization. 2 6 12
As Jiang Yuechu's enemies and cultivation realm rise, Dao Cultivation becomes the central constraint on her development. Individual upgrades grow from tens or hundreds of years to millions, forcing her to choose between improving existing techniques, recording powerful demons, refining Dao Chess Pieces, or retaining an emergency reserve. 33 275 564 699
Acquisition
Slaying cultivators and demons
Dao Cultivation is primarily awarded when Jiang Yuechu kills a cultivator, demon, or other qualifying creature. Its yield appears to reflect both the target's realm and total time spent cultivating. 2 104
- Demons generally provide more Dao Cultivation than humans of the same realm because of their longer lifespans and cultivation histories. 104
- Human cultivators remain a viable source because they are more numerous than demons. 104
- Not every slain creature can be recorded; the String-Hearing pig demons in Liangzhou provided Dao Cultivation but triggered no collection prompt. 11
- High-level human cultivators can eventually become extraordinarily profitable. Jiang Yuechu notes that one human opponent provided the equivalent of roughly 47 million years of Dao Cultivation. 819
Representative yields and costs
| Event | Dao Cultivation change | Notes |
|---|---|---|
| Killing Pei Changqing | +20 years | The first recorded gain; Pei Changqing was a String-Hearing Realm cultivator. 2 |
| Killing two pig demons | +60 years | Each String-Hearing Realm pig demon yields 30 years. 11 |
| Killing a Core Formation Flood Dragon | +645 years | Recording the same demon immediately costs 1,100 years, exceeding the kill reward. 86 |
| Killing Qiankun Demon King | +3,200 years | Recording its Shadow Copy costs 8,600 years. 251 |
| Killing Great Sage Huiyue | +148,921 years | Jiang Yuechu spends 84,320 years to record Huiyue afterward. 307 |
| Defeating Five Immortals Mountain's True Persons | +2.6 million years or more | The combined reward gives Jiang Yuechu a multi-million-year reserve. 408 |
| Killing Little Heavenly General | +4,723,655 years | The corpse disintegrates, preventing its use as a Heaven-Grade Dao Chess Piece. 748 |
| Killing a Flowing Cinnabar lifeform | +37 Dao Essence | Later-stage rewards are presented as Dao Essence rather than years. 817 |
Abilities & Functions
Direct enhancement
Directly consuming Dao Cultivation can grant immediate power, martial insight, and physical strength. Jiang Yuechu's first 20 years give her enough blade comprehension and strength to confront Tiger Mountain God, but the effect is treated as a short-term and inefficient use of the resource. 2
- Can rapidly increase combat capacity in an emergency. 2 748
- Can be burned in enormous quantities for a single decisive strike. Jiang Yuechu spends tens of millions of years to kill Little Heavenly General in one blow. 748
- Does not replace permanent cultivation, recorded demons, or technique development. 2 33
Demon recording and progression
Dao Cultivation pays the cost of recording demon Shadow Copies and advancing them through their internal progress tiers. Successful upgrades can grant martial arts, talents, divine abilities, demonization, and technique upgrades. 2 6 12
- Raising Tiger Mountain God to Vermilion-Dyeing costs 102 years and grants Tiger Dharma Heaven-Bestowed, Tiger Sha Blood Boil, and Supreme Fierce Tiger Quickblade. 6
- Raising Tiger Mountain God further through Eye-Dotting unlocks Tiger Demonization. 12 18
- Advancing Black Mountain Bear Lord to Heavenly Completion evolves the Mouth-Sealing Qi-Solidifying Method into the Primordial One-Qi Technique and grants Strength of Ten Thousand Jun. 123
- Advancing demons can be far more expensive than the reward gained from killing them, especially at higher realms. 86 251 413
Technique infusion
After Jiang Yuechu becomes an eighth-rank Team Leader, Dao Cultivation can be infused into martial arts and cultivation methods to raise their mastery directly. 33
- Tiger Roar Demon Suppression Blade reaches Supreme after consuming 260 years. 77
- Golden Lion Overlord Blade, Yin-Yang Vertical and Horizontal Hand, and Spring Leg Ground-Shrinking can all be learned through infusion; their initial study costs a combined 275 years. 92
- Costs rise sharply with the technique's realm and depth. The Perfect Unbreakable Method requires 5,200 years to reach Supreme. 278
- The Great Black Heaven Body-Forging Scripture requires 3,770,000 years for its final documented rise to Supreme. 564
Heavenly Demon Martial Drill
Unlocked upon Jiang Yuechu's entry into the Ink-Dotting Realm, the Heavenly Demon Martial Drill creates a separate internal world in which compatible recorded demons can deduce and cultivate designated techniques. 156
- Costs 10 years of Dao Cultivation per hour of deduction. 156
- Only Heaven-Made-progress demon souls can initially be used. 156
- A demon's compatibility with the assigned technique affects whether it can participate. 156
- Demons can reach an impasse if Jiang Yuechu cannot provide enough relevant cultivation material for further deductions. 258
Furnace smelting
The Martial Arts Arena later develops a Bronze Giant Cauldron that can consume Dao Cultivation together with existing talents or divine abilities to produce a new result. 442 443
- Smelting Mountain-Moving and Sea-Filling and Wide Learning and Strong Memory for 500,000 years produces the Source-Returning Demon Heart. 443
- The process is not reliably efficient: consuming Silver Bone Glazed Body, Taiyin Chain-Form, and another 500,000 years produces only the Sturdy Physique talent. 443
- Smelted abilities are removed from Jiang Yuechu after being used as ingredients. 443
Dao Chess Pieces
In the Chess-Player Realm, Dao Cultivation supports the cultivation methods and demon-body processing involved in Dao Chess Pieces, but cannot replace the required foundational materials. 631 662
- Dao Chess Pieces ordinarily require either Five-Qi Treasure Lands or Dao-Integration Materials as their base. 597 631
- Jiang Yuechu cannot create a Dao Chess Piece from nothing merely by spending Dao Cultivation. 631
- Improving the Chess-Condensing Method before condensation raises the initial quality of the resulting piece. 662 699
- The Prison-Suppressing Evil-Subduing Chess-Condensing Chapter consumes 15.2 million years to reach Perfection and a further seven million to reach Supreme. 699 734
Limitations
- Dao Cultivation is finite and must be allocated among survival, technique mastery, demon recording, deductions, and Dao Chess Piece development. 47 92 413
- Costs escalate dramatically at higher realms; even multi-million-year reserves can be insufficient for major upgrades. 413 564 619
- Recording a demon may cost more than its death yields. 86 251
- Jiang Yuechu cannot continue an infusion once her reserve is exhausted. 92
- Direct expenditure can create immense short-term strength but risks leaving Jiang Yuechu without a reserve for later threats. 275 413
