Darkness City
The tens of thousands of large mountains were so vast that they even exceeded Lin Dong's expectations. Moreover, even with Chen Gui, someone who was familiar with the terrain, leading the way, it was still two days later before they finally left this area.
Standing outside the area where tens of thousands of large mountains stood, Lin Dong glanced at the many untouched mountain ranges that seemingly cut across the sky. Then, he involuntarily sighed softly, before he circulated his Mental Energy and left a spatial stamp at this area. By doing so, if he wants to come back here in the future, he could use the spatial stamp that he left behind to directly tear the empty space and reach here. It would be much more efficient than before.
