Black Flame Demon Fox

Biodata

Power Progression

Habitat and Ecology

• Black Flame Demon Foxes inhabit cave networks among barren, low hills with gray-black rock, sulfurous air, and rising heat waves on the outskirts of the Star Dou Forest 30 34.
• They are naturally cautious and retreat deep into their intricate caves when they sense danger, making bait preferable to a direct search 30.
• Dream-Weaving Spiders are among their prey; Li Yi considered one an effective lure 30.
• A high-aged Dream-Weaving Spider could attract a Black Flame Demon Fox exceeding 800 years 30.

Appearance

An ordinary Black Flame Demon Fox has glossy black fur and a dark-red stripe running from its head down its spine to its tail. The specimen taken for Duan Fan's second Soul Ring was over three meters long 35.

• Fur: Glossy black 35
• Spinal marking: Dark-red stripe running head to tail 35
• Nine-Tailed variant: Duan Fan's manifested version has nine powerful tails and initially exceeds five meters in body length 36 43.
• Mature manifestation: Ten-thousand-year-level versions bear dark-golden patterns across their bodies 51.

Abilities & Traits

Black Flames

The species releases black flames. While the flames provide heat and destructive force, their primary value is enabling the fox's self-strengthening transformation 30 43.

• The Nine-Tailed manifestation can exhale black flames in wide torrents, incinerating Zhang Nanfeng's Ghost Vines on contact 43.
• It can condense a black fireball that detonates on impact, producing a fiery shockwave 36 43.
• The flames are not described as exceptionally powerful by themselves; their elemental advantage over plant-based Ghost Vines was decisive 43.

Fire-Bathing Growth

A Black Flame Demon Fox can enter its own flames, absorb their special power, and increase both size and combat power 30.

• Duan Fan's Nine-Tailed manifestation grew from roughly five meters to seven meters in body length after entering its black flames 36.
• In its enlarged state, it exceeded ten meters in total length including its tails and stood over four meters at the shoulder 36.
• The transformation allows it to follow up with stronger physical attacks and explosive black fireballs 36 43.

Creative Trait

The Black Flame Demon Fox possesses a creative ability that produces a stronger version of itself 30.

• This trait made it a suitable second Soul Ring candidate for Duan Fan's Fantasy Pen, whose soul skills turn drawings into living combat creations 30.
• Duan Fan's resulting skill, Nine-Tails, manifests a stronger, nine-tailed Black Flame Demon Fox rather than an ordinary specimen 36.

Story Role / Major Arcs

• Li Yi selected the Black Flame Demon Fox as one of the best candidates for Duan Fan's second Soul Ring because of its black flames, self-strengthening ability, and compatible creative trait 30.
• Duan Fan, Li Yi, and Li Ruolan reached the foxes' cave territory in the Star Dou Forest, intending to lure one out with a Dream-Weaving Spider 30.
• After Duan Fan revealed his extraordinary physique and twin Martial Souls, Li Yi reconsidered the conventional Soul Ring age limit and delayed the hunt 32.
• Ghost Leopard Douluo later captured a roughly 1,500-year Black Flame Demon Fox with ease. Duan Fan had his Dream-Weaving Spider kill it and absorbed its Soul Ring over three hours 34 35.
• The Soul Ring granted Duan Fan Nine-Tails, allowing him to draw and command a nine-tailed Black Flame Demon Fox with combat power sufficient to overwhelm ordinary Soul Exalts 36 37.
• The Nine-Tailed manifestation defeated Zhang Nanfeng's Ghost Vine techniques through black flames, fire-bathing growth, and overwhelming physical force 43 44.
• Years later, Duan Fan deployed eight ten-thousand-year-level Nine-Tailed Black Flame Demon Foxes against Golden Crocodile Douluo; all were destroyed by the peak Douluo 51 52.

Relationships

• Duan Fan — Killed a roughly 1,500-year specimen for his second Soul Ring; its traits became the basis of his Nine-Tails soul skill 35 36.
• Li Yi — Identified the species as a suitable Soul Ring target and explained its cave habitat, caution, prey, black flames, and self-duplication trait 30.
• Ghost Leopard Douluo — Captured the target specimen and evaluated the combat power of Duan Fan's Nine-Tailed manifestation 34 37.
