Xu Tang's immortal cave was located right in the middle of a mountain.
He had even set up numerous formations around the entrance to conceal it.
Furthermore, Xu Tang had laid out various maze formations and the like all across the surrounding mountain range.
It was fair to say that in all the years Xu Tang had lived here, not a single person had ever been able to find his immortal cave without his guidance.
Even on occasions when Xu Tang had brought a few close friends here to visit, those friends were completely unable to find the entrance again on subsequent visits.
Anyone wandering through these mountains without knowing the lay of the land would inevitably trigger the warning formations Xu Tang had established, prompting a reaction from him.
A flash of spiritual light flickered in Qin Xuan's eyes, while a faint glow emanated from the space between his brows.
Qin Xuan did not try to decipher the formations set up by Xu Tang; instead, he used the eye between his brows to peer straight through them and see the entrance hidden behind.
"Not bad. This is indeed an extremely secluded spot."
Judging by this immortal cave, Qin Xuan had a rough idea of Xu Tang's personality—he could be described as cautious to the extreme.
