Though the Tianlan Mountain Range is a perilous place, within the peril lies small segments of Cave Heaven and Blessed Land. The Demon Court's established sect is located within such a small section of Blessed Land in the Tianlan Mountains. After Hongjun Daoist Ancestor and others set up the Sect Protection Array, the massif became the best natural defense.
Various major forces have attacked the Demon Court multiple times to no avail, losing soldiers and generals, which is partially due to the perilous terrain of the Tianlan Mountain Range.
Relying on the Void-Breaking Moon Eyes, Sun Wukong flew straight into the Tianlan Mountain Range, passing through gaps that could trigger the mountain's Formation Prohibitions and Restraints without activating them. Thus, he arrived before the small section of Cave Heaven and Blessed Land deep within the Tianlan Mountain Range, where the Demon Court's sect is located.
