The sharp spear formed by demonic qi once again bombarded the great formation.
This spear dissipates and reforms, reforms and dissipates, like a battering ram, repeatedly striking the solid "gate" of the Northern River Great Formation.
"It's not working, the Demon Race's offensive is far more ferocious than anticipated. At this rate, the Northern River Great Formation won't hold for more than a day," Wu Yan, the commander at Northern River Border, concluded within the glow of the barrier.
Northern River Border ranks among the top three of the Human Race's seventeen fortresses, surpassing Falling Goose Pass in scale, and thus boasts a significantly stronger City Defense Formation.
Under normal circumstances, even facing the siege formation of over three thousand Seventh Grade Demonic Cultivators, with the aid of the Northern River Great Formation, tens of thousands of cultivators at Northern River Border could defend the fortress for at least three days.
