As for the 'Xuanyang Two Immortals'.
No matter how powerful an Upper Immortal is, there is still a qualitative difference from a True Immortal, difficult to bridge.
True Immortals have endless lifespans; they've seen too many arrogant Upper Immortals.
The Xuanyang Two Immortals are not the first case.
...
Time passes.
In the blink of an eye, several months have gone by.
At the southeastern border of the territory under the Black Vulture Palace's control, outside Xuanyang Mountain, there are already many Demon Kings, demons, and passing Loose Cultivators and Upper Immortals gathered.
They have more than enough lifespan, so waiting outside the mountain for decades is of no concern.
Being able to witness a True Immortal in action, to see the gap between themselves and a Peak Immortal and a True Immortal, is worth the wait.
Thus, they continue to gather.
