The Huan Yuan Heavenly Cauldron floated at the center of the raised platform, its body flowing with an exceptionally restrained, lustrous white glow.
The pill embryo, refined to the utmost limit, slowly revolved within the cauldron. Purple, gold, and azure medicinal essence intertwined layer upon layer, while threads of lightning Dao aura were sealed entirely within the pill.
As the pill's essence grew increasingly solid and its Dao aura took root completely, the destructive pressure filling heaven and earth had already climbed to its peak.
The heavy Black Demon Lightning clouds overhead churned violently. Black lightning crisscrossed within them, releasing ear-piercing crackles. All the spiritual energy throughout Saint Dan City froze, and the Dao aura in every direction fell utterly silent.
That terrifying power, capable of erasing Battle Venerables and severely wounding Half-Saints, had firmly locked onto Yao Xuan atop the platform!
The overwhelming force of heaven and earth made everyone's bodies tense, their breathing sluggish and heavy.
The next instant!
The thunderclouds in the sky suddenly collapsed, tearing open a massive black hole several zhang wide at their center. Its depths were dark and profound, as though they connected to a chaotic void that could annihilate all things.
A terrifying aura capable of suppressing eternity poured forth. An enormously thick pillar of black lightning, carrying the supreme might to destroy souls and shatter origins, tore through the sky and crashed down upon Yao Xuan's head with lightning speed!
"Not good! The pill lightning has descended!"
Xuan Kongzi and the other two's expressions changed drastically. Their bodies instantly moved, all the Dou Qi within them surging as they prepared to lend aid.
They knew all too well how terrifying Black Demon Lightning was. Even an Eight-Star Battle Venerable's body and cultivation were no different from ants before such heavenly tribulation
