Jade Python Snake	13	Dugu Yan's original Martial Soul; its inherited backlash poison requires Dugu Bo's regular suppression.
Jade Scale Dragon	14	The Qiluo Tulip purges Dugu Yan's backlash poison and evolves her Martial Soul into a True Dragon-type Martial Soul. Her poison becomes a controllable power source.

Background / History

A Martial Soul is the basis of a soul master's combat power and cultivation. Its quality affects potential, while its attributes shape a user's soul power, soul rings, physical traits, and available soul skills. Ordinary accumulation of soul power alone is insufficient for higher-level advancement; deeper progress can require comprehension of a Martial Soul's origin. 1 44

Martial Soul Evolution is described as a qualitative change of essence rather than a merely cosmetic transformation. It can purge inherent flaws, elevate potential, reshape the user's body, and alter the nature of existing attributes. 4 13 14

Dugu Bo identifies evolution as the true cure for the Jade Python Snake Emperor's backlash poison. After consuming the Earth Dragon Golden Gourd, the serpent Martial Soul's origin is remade into that of the Nine Nether Divine Dragon, while its poison is transformed from an uncontrollable biological toxin into Netherworld Power. 1 3 4

Dugu Yan later undergoes a similar, lesser evolution through the Qiluo Tulip. Her Jade Python Snake becomes the Jade Scale Dragon, a top-tier True Dragon-type Martial Soul comparable to the Golden Sacred Dragon; its former backlash poison becomes true dragon poison under her control. 14 15 24

Properties

Evolution

Martial Soul Evolution can be induced by exceptional resources, including immortal herbs.

• The Earth Dragon Golden Gourd carries life energy, Dragon Might, and earth-attribute power capable of remaking a serpent Martial Soul's origin. 2 4
• The Qiluo Tulip is an immortal herb that elevates Martial Soul quality, purges flaws, and reshapes the user's body. 13 14
• Evolution can convert a harmful inherited poison into a wielder-controlled source of power. 4 14
• A sufficiently profound evolution may attract heavenly tribulation by touching the realm of gods. 3 5

Soul Rings

Soul rings are tied to a Martial Soul and provide soul skills.

• Dugu Yan's Jade Scale Dragon's natural suppression over snake-type Soul Beasts reduces the difficulty of absorbing their soul rings. 16
• Her evolved Martial Soul allows the absorption of a twelve-thousand-year Venom Swamp Python ring as a fourth ring, producing the soul skill Jade Scale Poison Domain. 17
• Heavenly tribulation can temper a divine-grade Martial Soul's rings; Dugu Bo's configuration becomes seven black and two red rings. 5 6
• The Nine Nether Divine Dragon Art includes a Ring Refining Chapter for cultivating soul rings over time. 10

Martial Soul Origin

The origin of a Martial Soul determines the deeper path of advancement.

• Advancement beyond level 96 requires insight into the Martial Soul's origin rather than further accumulation of soul power alone. 44
• The Nine Nether Refining Chapter is intended to guide Dugu Bo's comprehension of the Nine Nether Divine Dragon's origin. 44
• The Nine Nether Divine Dragon's origin contains an inheritance space and the legacy of the Nine Nether Divine Dragon Art. 9 10

Notable Abilities

Nine Nether Divine Dragon

A divine-grade dragon Martial Soul wielded by Dugu Bo after his evolution.

• Commands nine dimensions of Netherworld Power: Nether Poison, Nether Earth, Nether Thunder, Nether Cold, Nether Domain, Nether Might, Nether Soul, Nether Silence, and Nether Annihilation. 9
• Its Netherworld Power combines poison, earth, and the judgment power of heavenly tribulation. 6
• Its dragon might causes instinctive fear in other Martial Souls, including Gui Mei's Ghost Shadow. 59
• It grants the Nine Nether Divine Dragon Art, whose six major chapters cultivate the soul, body, soul power, soul rings, Martial Soul strength, and Netherworld Power. 10
• The technique can continue operating automatically at reduced efficiency while its practitioner sleeps, fights, or performs other activities. 10

Jade Scale Dragon

A True Dragon-type poison Martial Soul wielded by Dugu Yan.

• Possesses both the poison attribute and the physical advantages of the Dragon Clan. 14
• Its dragon might naturally suppresses sub-dragon and snake-type Soul Beasts. 16
• Transforms former backlash poison into controllable true dragon poison. 14 17
• Its fourth soul skill, Jade Scale Poison Domain, creates a poisonous area-of-effect domain that can kill enemies near Dugu Yan's strength and continuously weaken stronger opponents. 17
• The poison domain is ineffective against opponents with top-tier detoxification methods or toxin immunity. 17

Trivia

• Dugu Bo's evolution changes his Martial Soul without immediately raising his soul power from level 92; the increase to level 93 occurs through the subsequent heavenly-tribulation baptism. 4 6
• Unlike Dugu Bo's divine-grade evolution, Dugu Yan's Jade Scale Dragon does not trigger heavenly tribulation or alter the colors of her first three soul rings. 14
• Practitioners of the Nine Nether Divine Dragon Art gradually develop deep trust and faith toward Dugu Bo, a hidden effect of the technique that binds their fates to him. 50 58
