"Boom!"
A dull sound resonated, and instantly, a purplish-red flame emerged from the center of the altar. However, this time the flame was far more exaggerated, soaring up to over ten meters high like a purple sword piercing the sky. Looking from afar, it was awe-inspiring; no one expected to witness such an unbelievable sight!
Yet, everything did not stop there. The handful of black-clad figures suddenly took out black boxes and tossed them into the purplish-red flame at the altar's center, and instantaneously the super flame over ten meters tall surged again, soaring nearly twenty meters high, invoking awe from those watching from afar.
