An unused shelter definitely had a huge attraction, enough to make countless survivors go crazy!
This was a matter of great importance, so the fierce dragon Hall was extremely cautious in their actions, hoping to keep this secret for a longer time.
Therefore, even though he had invited Tang Zhen to help, Wang Wu did not mention anything about the sanctuary. This was to prevent Tang Zhen from having any ill intentions or leaking the information about the sanctuary.
Fortunately, the cave that led to the sanctuary had collapsed and was completely covered by gravel.
This way, when Tang Zhen was killing the mutated monsters, as long as he did not deliberately observe, he would not discover any abnormalities in the karst cave. The chances of the shelter being exposed would be greatly reduced!
Of course, the most crucial point was how to invite Tang Zhen to take action!
