No one knew how much time had passed in the secret zone because there was no day or night.
Among the disciples of the 12 peaks, Chen Jingzhai and the others were not the only ones who were lucky enough to find a cave residence.
However, some disciples could not obtain the opportunities inside even if they found the cave residence.
This was because only formation masters could break the Restrictions.
Even if they could crack it with brute force, the grade of the cave residence was not high, so how much could they gain?
Fortunately, the secret zone was huge, and opportunities were not limited to caves.
There were also precious minerals, treasures, spiritual plants, medicinal herbs, and so on.
Since this secret zone housed the immortal abode of the celestial being Hongdu, it naturally had great potential.
It was natural to have rich resources and many spiritual objects.
