The Xuanwu Four-polar Boundary Array buzzed as it operated.
Array patterns spread out, and amid the emergence and disappearance of runes, it revealed a fierce visage to the enemies who attempted to breach the array.
Within a radius of dozens of kilometers, countless Heavenly Earth Spiritual Qi converged to form meteorites of flame that fell from the sky, each capable of annihilating a group of Foundation-building cultivators.
Now, these meteorites fell densely upon the advance tank troops without end!
"Fire!"
Countless tank commanders roared.
The tanks spat flames, and trails of white streaked across the sky; the dense group of Armor-piercing Shell Group whooshed toward their target, shielding the main forces with a counterattack.
Boom!
The sound of explosions reverberated, Spiritual Light shattered, fragments of armor-piercing bullets scattered, the heavy meteorites of flame were torn apart, breaking into large chunks before completely dissipating into Spiritual Light.
