Mantra of Burning Upgraded, Around Low to Mid Profound Tier

"Now that it had absorbed so many flames, the Mantra of Burning had already been upgraded."

Xiao Changge said.

In Battle Through the Heavens, the Mantra of Burning's ability to "absorb flames to raise its rank" was a rule-level bug—it did not advance like ordinary cultivation methods, accumulating Dou Qi through meditation. Instead, it treated Heavenly Flames as fuel, devouring its way from low Yellow Tier to beyond Heaven Tier, dragging the host's cultivation, alchemy skills, and entire combat system upward along with it. Just how powerful was it? The mechanism and actual combat results made that clear.

Core mechanism: devour flames to evolve, with endless rank stacking.

Its starting point was extremely low: it began as low Yellow Tier, the most worthless grade in the entire Dou Qi Continent. Yet by design, it could evolve without limit, ultimately surpassing Heaven Tier and sharing the same origin as the Tou She Ancient God.

Its fuel came in three categories:

High-tier Beast Flames, such as the Amethyst Winged Lion King's Purple Flame, could push it up a small rank in the early stages.

Ordinary Heavenly Flames were the main fuel; devouring one could raise it by an entire major grade.

The farther it progressed, the more top-tier Heavenly Flames it required. Beast Flames became completely useless in the later stages.

There was also an exclusive cost: once one cultivated the Mantra of Burning, one could no longer cultivate other methods. Switching methods meant dispersing all one's cultivation and starting over. Devouring Heavenly Flames was also a near-death process; if one could not withstand the backlash, one would turn to ash.

It could be said that this cultivation method was extremely difficult to cultivate, and once cultivated, no other methods could be practiced.
