The strand of flame directly incinerated the Fire Monarch's Divine Sense into nothingness and simultaneously began to frenziedly devour the Fire Monarch's own flames, rapidly growing in strength.
Filled with terror, the Fire Monarch, whose cultivation level was much higher than the Fiery Flame Demon King and was a being who had practically stepped into the True Immortal Realm, immediately redirected all of his cultivation within his body, enveloping the strand of Divine Flame completely.
Although the fire was extremely weak, it devoured all flames and was exceedingly difficult to deal with.
The Fire Monarch exhausted every method but could not completely extinguish it.
In the end, he gritted his teeth and used a portion of his cultivation to wrap around the fire, then expelled it from his body.
