BOOOM—!
Ferocious shockwaves appeared in the sky.
The residual mana that spread from the shockwaves enveloped the entire battlefield.
BANG—!
This exchange had been going on for about a day now, and it had started to become progressively stronger. Both sides were still not going all out as they were gauging each other and buying time for those fighting below. Whenever the situation shifted for one side, the other would quickly interfere to return the balance.
"Why don't you guys open up the barrier? The situation looks tough for you guys."
The Marquis ranked demon pointed at the battle that was ensuing below as he coldly laughed.
"Will you guys be able to last without it?"
"You're really full of nonsense."
Waylan glared at the Marquis-ranked demon. His hand that held onto the large broadsword swung downward.
