Several dozen meters high, the cliff was not easily accessible to ordinary people. In the past, there would have been hidden sentries stationed here, and if they encountered someone who could pass through, they would use a mechanism to pull them up. But today, it was evident that no one was guarding here.
Fortunately, Yang Chen and the other three were adept at light work, so they were able to leap up the cliff with some difficulty, using protruding rocks as footholds.
Upon reaching the top of the cliff, they found a relatively flat piece of land. If one didn't look carefully, they wouldn't notice a hidden lift mechanism in a corner of the cliff.
This device would naturally not be destroyed by anyone. After all, even if the enemy had already entered, they would not want to cut off their retreat. Few people could ascend or descend this cliff by their own strength alone.
