But it failed.
You can win many times, but in a place like Kunlun Mountain, if the army loses even once, cuts off the retreat and loses supplies, no one can possibly return. Those who do escape must consider if they've been possessed by the Divine Teachings, their bodies claimed. Thus, after repeated catastrophic destructions, the strength of the Kun Province's Immortal Army was severely weakened, leading to its silent demise.
Xuanmen also once tried to conquer Kunlun. In fact, Xuanmen was quite successful. Back in the days of the Xuantian Sword Ancestor, when the three elders and four ancestors were present, they hunted the demonic path across the mountains, almost driving non-Xuanmen factions in Central Plain into extinction at Kunlun. They launched northern expeditions, western campaigns; Xuantian's reach extended across Kunlun, leaving behind numerous sword formations and true teachings.
But it still failed.
