Power Progression
| Stage / Realm / Level | Chapter | Notes |
|---|---|---|
| Outer Gang | 133 | Zhang Su perfects the Outer Extreme Divine Art and completes a seven-in-one fusion, transforming Pure Yang Force into Pure Yang Gangjin. The resulting Outer Gang covers his skin as a thin protective layer. |
| Inner Gang | 136 | After perfecting the Inner Extreme Divine Art, Zhang Su gradually extends Gangjin from his skin through muscle, bone, and into his internal organs. |
| Inner and Outer as One | 145 | Zhang Su perfects the Wuji Divine Art. Gangjin can circulate to any part of his body at will, leaving no remaining physical weak point. |
| Five Elements Gangjin | 147 | Zhang Su perfects the Great Five Elements Divine Art, forming Second-Class Five Elements Gangjin. It possesses the cyclical, self-generating qualities of the Five Elements and can likewise achieve internal-external unity. |
| Primordial Unity Gangjin | 148 | Zhang Su fuses Pure Yang Gangjin and Five Elements Gangjin through the Gangjin Fusion Method. The resulting Primordial Unity Gangjin is a pinnacle First-Class Gangjin that absorbs both original forms. |
| Taiji Gangjin | 153 | Zhang Su perfects the Ice Baleful and Fire Baleful Divine Arts. Their opposing Gangjin merge into Taiji Gangjin, a pinnacle First-Class form balancing yin and yang, hardness and softness. |
| Perfect Gangjin | 153 | Zhang Su fuses Primordial Unity Gangjin and Taiji Gangjin. A trace of Spirit Essence helps the new Gangjin achieve seamless perfection, surpassing First-Class Gangjin. |
| Houtian Realm | 154 155 | Having completed Perfect Gangjin—also called Taiji Primordial Unity Gangjin—and given rise to internal power, Zhang Su advances beyond the Gangjin Realm into the Houtian Realm. |
Realm Stages
| Stage | Protection and characteristics | Next step |
|---|---|---|
| Outer Gang | Gangjin manifests over the body as an invisible armor-like layer. It generally deflects blades, swords, and arrows, while enhancing the force of a martial artist's strikes far beyond a Danjin eruption. 123 133 | Extend Gangjin inward. |
| Inner Gang | Gangjin protects the five viscera and six bowels, greatly improving resistance to heavy impacts and endurance in battle. 123 136 | Achieve complete internal-external circulation. |
| Inner and Outer as One | Gangjin reaches every part of the body and can be reinforced wherever needed. At this pinnacle stage, the practitioner has no obvious bodily weakness. 123 145 | Temper Gangjin and attempt to give birth to internal power, advancing toward the Houtian Realm. 145 |
- A peak Gangjin practitioner may postpone the birth of internal power in order to improve their Gangjin quality first. Zhang Su deliberately delayed his Nine-in-One and Houtian breakthrough because advancing with Third-Class Pure Yang Gangjin would limit the quality and potential of his future internal power. 145
Characteristics
- Gangjin is a qualitative step above Danjin: a Gangjin martial artist can protect their entire body while delivering strikes several times—or even ten times—stronger than a Danjin eruption. 123
- From Mingjin through Gangjin, martial artists are still using Internal Force. Gangjin represents Internal Force refined and controlled to its peak, while the birth of internal power in the Houtian Realm is the true higher-order transformation. 123
- The Three Extremes Divine Arts must be cultivated in sequence—Outer Extreme, Inner Extreme, then Wuji—corresponding respectively to Outer Gang, Inner Gang, and Inner and Outer as One. 123
- Fine control over Internal Force is central to Gangjin cultivation. Specialized arts such as the Flying Knife Technique can improve this control and accelerate a practitioner's progress. 123 133
- Outer Gang is not absolute protection. Zhang Su's Wind-Thunder Sword Technique, enhanced by Divine Intent and Danjin, initially failed to pierce Chu Hanjiang's throat due to his unified Gangjin. 127
- Sufficiently overwhelming force can shatter Gangjin. Zhang Su broke Chu Hanjiang's peak Gangjin with the Twelve-Fold Killing Sword and Pure Yang Force. 127
- A practitioner at the peak of Gangjin may still be unable to advance naturally. Chu Hanjiang spent over twenty years reaching internal-external unity but lacked the resources and guidance needed to reach the Houtian Realm. 127
- High-quality Gangjin can substantially narrow the gap between cultivation realms. Zhang Su's Primordial Unity Gangjin allowed him to contend head-on with Zhao Qi, a Houtian martial artist who had advanced using First-Class Gangjin. 148
- Successful Gangjin fusion can replace its constituent forms entirely. Primordial Unity Gangjin devoured Zhang Su's Pure Yang and Five Elements Gangjin, while Taiji Gangjin replaced his Ice Baleful and Fire Baleful Gangjin. 148 153
- Zhang Su's Perfect Gangjin is also known as Taiji Primordial Unity Gangjin. Its complete method was preserved as a standalone Gangjin art by Primordial Unity Peak. 154 158
Gangjin Quality
| Quality tier | Ranks | Implications for internal power |
|---|---|---|
| Lower three grades | Ninth, Eighth, Seventh | Giving birth to internal power is largely dependent on luck, even after lifelong cultivation. 141 |
| Middle three grades | Sixth, Fifth, Fourth | Internal power can usually be cultivated, but its quality and power are comparatively ordinary. 141 |
| Upper three grades | Third, Second, First | Internal power can reliably be cultivated and possesses distinctive traits, great power, and broader potential. 141 |
| Perfect Gangjin | Above First Grade | A rare, seamless Gangjin said to appear once in ten thousand cases or less. Its resulting internal power is of the highest quality and has boundless potential. Zhang Su successfully achieved this state through the fusion of Primordial Unity and Taiji Gangjin. 141 153 |
Perfect Gangjin
Before Zhang Su's breakthrough, no definitive or universally reliable method for Perfect Gangjin was known within the Haojin Upper Sect. Historical cases were believed to result from unpredictable circumstances, including life-or-death breakthroughs and rare treasures. 142
Zhang Su subsequently documented a complete route: Pure Yang Gangjin was fused with Five Elements Gangjin into Primordial Unity Gangjin; Ice Baleful and Fire Baleful Gangjin were merged into Taiji Gangjin; then Primordial Unity and Taiji Gangjin were fused with the aid of a trace of Spirit Essence from the Azure Wood Spirit Pill. 148 153
After Zhang Su submitted his cultivation notes, Primordial Unity Peak's elders determined that the process was theoretically replicable. The resulting Taiji Primordial Unity Gangjin manual was placed in the Martial Transmission Hall, though its cost and difficulty ensure that it remains inaccessible to most disciples. 158
Gangjin Fusion Method
The Gangjin Fusion Method improves a practitioner's Gangjin by cultivating compatible Gangjin-producing arts and merging them. It is exceptionally dangerous: incompatible or mishandled fusion can cripple cultivation or cause qi deviation. 141 142
| Intended result | Required foundation and arts | Notes |
|---|---|---|
| Primordial Unity Gangjin | Pure Yang Gangjin + Five Elements Gangjin from the Great Five Elements Divine Art | A top-tier First-Class Gangjin of Primordial Unity Peak, combining Yin, Yang, and the Five Elements. Zhang Su successfully achieved it after allowing the two conflicting Gangjin to produce a common fused core naturally. 142 148 |
| Taiji Gangjin | Ice Baleful Gangjin from the Ice Baleful Divine Art + Fire Baleful Gangjin from the Fire Baleful Divine Art | A top-tier First-Class Gangjin that develops Yin-Yang Duality through extreme fire and ice. Zhang Su successfully cultivated it after the Ice Baleful and Fire Baleful Gangjin merged. 142 153 |
| Myriad Phenomena Gangjin | Pure Yang Gangjin + Four Symbols Divine Art | A First-Class Gangjin considered somewhat inferior to Primordial Unity and Taiji Gangjin, but relatively less difficult to cultivate. 142 |
| Seven Stars Gangjin path | Pure Yang Gangjin + Seven Stars Divine Art | Can elevate Pure Yang Gangjin to First-Class, though its final quality is below Primordial Unity and Taiji Gangjin. 142 |
| Three Spirits Gangjin path | Pure Yang Gangjin + Three Spirits Divine Art | Can elevate Pure Yang Gangjin to First-Class, though its final quality is below Primordial Unity and Taiji Gangjin. 142 |
| Perfect Gangjin | Primordial Unity Gangjin + Taiji Gangjin + a trace of Spirit Essence | Zhang Su's successful route. The two pinnacle First-Class Gangjin still collided violently, but the Azure Wood Spirit Pill's Spirit Essence enabled the final seamless transformation. 153 158 |
Documented Forms
| Practitioner | Gangjin | Notable feat |
|---|---|---|
| Zhang Su | Third-Class Pure Yang Gangjin | Its defensive power after sevenfold fusion surpasses Zhou Dingshan's Four Elements Fusion Gangjin. 133 141 |
| Zhang Su | Second-Class Five Elements Gangjin | Formed after perfecting the Great Five Elements Divine Art; its endlessly cycling Five Elements nature makes it stronger than his original Pure Yang Gangjin. 147 |
| Zhang Su | Primordial Unity Gangjin | A pinnacle First-Class Gangjin created by merging Pure Yang and Five Elements Gangjin. Its power exceeded Zhao Qi's ordinary First-Class Gangjin despite Zhang Su remaining at Gangjin. 148 |
| Zhang Su | Taiji Gangjin | A pinnacle First-Class Gangjin formed from the balanced fusion of Ice Baleful and Fire Baleful Gangjin. 153 |
| Zhang Su | Perfect Gangjin / Taiji Primordial Unity Gangjin | Formed by fusing Primordial Unity and Taiji Gangjin with Spirit Essence. Its complete cultivation process was later preserved by Primordial Unity Peak. 153 154 158 |
| Chu Hanjiang | Peak Gangjin; Inner and Outer as One | His Gangjin protected even his throat, blocking Zhang Su's initial Wind-Thunder Sword strike. 127 |
| Zhou Dingshan | Bedrock Gangjin with Four Elements Fusion | Stacks four layers of Gangjin and merges them into a stronger defensive form. 127 130 |
| Ye Ling | Peak Gangjin; Inner and Outer as One | Her Gangjin covers both skin and internal organs, allowing her to buffer external impacts. 129 |
| Song Yan | Second-Class Gangjin | His Gangjin was shattered in one strike by Zhang Su's Fast Sword Style. 144 |
Known Limitations
- A Gangjin practitioner's defense depends on both the quality and depth of their Gangjin; higher-grade Gangjin is more difficult to overcome and offers greater potential for future internal power. 141
- Gangjin can be defeated by attacks whose speed, sharpness, or explosive force exceed its defensive limit. 127 144
- Zhang Su judged that even his Divine Intent-enhanced Flying Knife Technique could not pierce a Gangjin practitioner's protective layer. 133
- Reaching Inner and Outer as One does not itself create internal power; the practitioner must still temper Gangjin and successfully generate that higher-order force to enter the Houtian Realm. 145
- Multiple Gangjin forms naturally conflict within the body. Even Pure Yang and Five Elements Gangjin, which are theoretically compatible, initially exploded upon contact and damaged Zhang Su's internal organs. 148
- Fusion requires extraordinary control, a sufficiently strong foundation, and often rare opportunities or treasures. Without Zhang Su's trace of Spirit Essence, the unstable fused Gangjin produced by Primordial Unity and Taiji Gangjin would not have reached Perfect Gangjin. 148 153
