In this era, there might have been Upper Immortals bold enough to challenge True Immortals, but none managed to cause a major uproar.
The Xuanyang Two Immortals were the first widely known example.
Moreover, their battle achievements were glorious.
Thus, in a short span of time, the name 'Xuanyang Two Immortals' trampled over 'Black Vulture Emperor,' resounding throughout Shenzhou, bringing honor to numerous Upper Immortals who felt proud by association.
Such a significant event was naturally known to Liu Xing.
What he didn't know was that Zhou Yan, by sheer coincidence, happened to be in the Southern Border during this time, and precisely near Black Vulture Palace, making preparations to establish a Daoist school.
