The Black Dragon Vanguard General's enormous dragon claws unfurled, and dark clouds rose behind it,
instantly, the Black Flood Dragon opened its mouth and spat out a huge black flame that was over ten meters in diameter toward Elder Xuan.
Elder Xuan silently made up his mind, and instantly, numerous runes appeared beside Elder Xuan.
The runes surrounded Elder Xuan and shone at the same time. The powerful light rapidly became transparent and resplendent, as if it was made of diamond. The two diamond lights condensed into one in the air and met the black flame.
"Hong --"
For a moment, the mountains and the earth shook. Even if their battle was ten thousand meters high in the sky, a sudden collision would cause the mountains and the earth to shake.
At this moment, the entire world was shaking.
The sky was filled with incomparably violent energy.
