"Boom!"
Dragon Demon Monarch and Shadow Demon Monarch exchanged a glance and saw the cold look in each other's eyes. And after that, a powerful pressure burst out from their bodies, pressuring the entire world. It was as if millions of tall mountains were pressing down on them, causing the entire world to be filled with intense pressure.
In an instant, Dragon Demon Monarch and Shadow Demon Monarch formed seals with their hands. Boundless energy swept out, turning into a torrent of energy that crashed down toward Fire Emperor. The boundless energy was killing everything in its path, causing the entire heaven and earth to change color.
Facing this terrifying attack, Fire Emperor's facial expression changed dramatically. He hurriedly circulated the energy in his body and defended himself with all his strength.
