Nether Flame Demon Saint!

A ball of Heavenly Flame suddenly rose in Ning Luo's palm, directly engulfing the ancient map.

Ning Luo's sudden action startled Yao Lao. Just as he was about to stop him, his pupils abruptly shrank. "Why can't this ancient map be burned?"

Hearing Yao Lao's words, Ning Luo and the other two hurriedly turned their gazes toward the flames. Sure enough, no matter how Ning Luo's Heavenly Flame burned, the ancient map, which looked as though it could be torn apart with a single tug, remained completely unmoved, showing no sign of turning to ash.

Ning Luo froze for a moment, then hurriedly urged the Heavenly Flame on.

"Whoosh, whoosh."

The flames blazed fiercely, their scorching heat warping the surrounding space. Yet no matter how much Ning Luo intensified the flames, the ancient map still showed no sign of turning to ash. However, as the fire grew more violent, the patterns on the map gradually began to glow, as though they were about to burst free from it.

As the flames burned ever more fiercely, the patterns on the ancient map grew brighter and brighter. At a certain moment, the map suddenly trembled. The patterns leaped directly off the map, transforming into lines of ancient text that floated in the air before them.

Twin moons appear together.

Nine stars become one.

A tide of heaven and earth.

The demonic flame descends.

Yao Lao slowly read out the ancient words, and a look of shock gradually appeared on his face.

"What does this mean?" Ning Luo frowned slightly, still unable to understand the meaning behind it.

Yao Lao let out a soft breath and said quietly, "Twin moons appearing together and nine stars becoming one refer to a special celestial phenomenon. But such a phenomenon only occurs once every thousand years.
