The Demon Court had long coveted the seven passes that had suppressed them for nearly ten thousand years. If they could capture just two, the defensive line of the Six Sects would be riddled with holes. The Demon Court would then be able to seize the strategic initiative, freely invading the Six Sects' territory through the gaps in their defenses and completely reversing the situation where the Six Sects had been slowly encroaching upon their lands for tens of thousands of years.
But of course, the Demon Court was not the only one to realize this.
After determining the situation was untenable, the Cultivators stationed at Celestial Radiance Pass and Pingyang Pass triggered the Grand Arrays to self-destruct. Although traitors colluding with the Demon Court prevented their complete destruction, the two passes were still severely damaged.
