Heavenly Flame Qi Refining Tower

Biodata

Structure and Cultivation

• The tower is black and buried underground, with a ninth-floor cultivation room documented 22.
• It stands above a pool of magma. Fire-attribute energy is especially concentrated inside, making the environment advantageous for fire-element cultivators but less suitable for ice-element cultivators 22 39.
• A Heart Flame Projection can appear within a visitor. Passing Dou Qi through it tempers and condenses that Dou Qi 22 23.
• Cultivation rooms require Fire Energy, spent through crystal cards inserted into a slot. A day in the ninth-floor room costs 30 days of Fire Energy 22 23.
• Crystal-card rank limits floor access: black cards permit the first two floors, while blue cards permit the third and fourth. Azure, red, and purple are the remaining ranks in ascending order 34.

Risks and Precautions

• Heart Flame Projection: Visitors can guard their minds against it; if it takes hold, they can push Dou Qi through it 35.
• Meridian damage: The ninth floor’s powerful projection can strain or burn a cultivator’s meridians. Elder Huo advises keeping a Pulse-Protecting Pill ready 23.
• Fire poison: Long sessions can cause fire poison to accumulate. Wu Bai uses a Mind-Cleansing Pill to clear signs of violent fire energy, and later takes a Zen Heart Pill before an extended seclusion 23 38.
• Time between sessions: Students must allow the fire heat in their bodies to dissipate; most cannot train in the tower every day 39.

Story Role

• Elder Huo introduces Wu Bai to the tower during his early admission to the Inner Academy, guides him through his first Heart Flame Projection, and gives him a purple card holding 10,000 days of Fire Energy 22 23.
• Wu Bai trains on the ninth floor for over three months before breaking through to Great Dou Master. He subsequently uses its Heart Flame to refine and stabilize the Dou Qi gained from his Three-Pattern Green Spirit Pill 23.
• After reaching Dou Ling, Wu Bai returns to the ninth floor to temper his Dou Qi. The Yellow Springs Demon Saint also descends beneath the tower to investigate what lies below it 29.
• Wu Bai later spends more than seven months in uninterrupted seclusion there, rising from One-Star to Eight-Star Dou Ling. Concerned that this rapid progress has left him unsteady, he decides to stay out of the tower for several months 39 40.
