Occasionally, a strong Frenzy Demon would crash into the Shield Wall, but it was like hitting a steel mountain, futilely waving its weapon, only to be simultaneously pierced and pinned down by several Long Spears beneath the wall.

Karas almost pressed his beak against the cold stone ledge, his voice distorted with extreme shock, "They... they're slaughtering! Slaughtering demons like mowing wheat! Those demons couldn't even warm up the wall!"
Aryan's silver-gray eyes were also filled with shock as he stared intently at the dark gray barrier, watching the silent and efficient killing machine: "Discipline... perfect discipline, precise command, and... that absolute calmness in the face of casualties."
