Chapter 663: Chapter 659, the most important thing before the expedition

The priest had given up the idea of fighting with a monster that he could not kill.

Escape... the only way to be rescued was to escape from here.

The priest did not hesitate and immediately ran to the other end of the corridor. There was a window there. He could see the endless void outside through the glass, and the voice of his lord calling to him.

He immediately tried to push the window open with his hands, but no matter how hard the priest tried, the window did not budge.

Was it locked?

He could not care less. The priest took out his magic staff and aimed it at the window, chanting a fireball spell.

Scorching flames emerged from the tip of the magic staff. The heat and destructive power it released was enough to pierce through a steel shield.

The fireball hit the glass, and a large amount of flames bounced back and enveloped the entire corridor. When the flames dispersed, the glass in front of the priest was intact.

Impossible!
