The sky turned both fiery and icy; one side seemed to be burning, giving off an incredible heat, while the other seemed to be frozen, giving off a bone-chilling coldness. It was the fiery and icy aura that caused the soldiers to tremble and feel terror.
"Charge!!" the system main city soldiers continued to roar and rush at the Inner Great Wall with immense battle intent. Their shouts and stamping of the ground shook the surrounding hundreds of kilometers.
At that moment, two orbs that were 1,000 meters wide appeared in the sky: one gave off blistering flames while the other gave off bone-chilling coldness. The two orbs slowly fused together, giving off an aura of annihilation. Even the City Lords were greatly dismayed and hurriedly looked over.
The two gigantic orbs were soon fused into one orb of fire and ice by Binoche and Kerache. Some places gave off cold air while other places had flames; it looked incredibly mystical and dangerous.
