On the other side, after returning to the wooden building, Granny Sun sat in the hall for a long time before suddenly getting up and walking into the back hall.
On the wall of the back hall hung an octagonal copper mirror. Granny Sun waved her hand, and the mirror began to creak and turn. Following its movement, a stone block about six feet square on the wall slowly sank down, revealing a pitch-black cave entrance.
Inside the cave entrance, a faint light of fire could be seen, and on the ground stretched a winding stone staircase leading downward.
Granny Sun followed the stone staircase down into a gloomy underground stone chamber.
Within the stone chamber, there was a large rectangular stone table with several gray-white stone chairs with backs around it, upon which sat seven or eight figures. The aura of most of them was strong; nearly all were Great Mahayana Stage Cultivators.
