"It seems I must go to the underground palace and take a look." Qing Shuang made up her mind; she needed to enter the underground palace and uncover the truth.
Qing Shuang quietly left the side hall and continued searching the Imperial Palace. She knew the entrance to the underground palace must be very well-hidden and heavily guarded, and finding it would be no easy task.
After some searching, Qing Shuang finally discovered a hidden rockery near the emperor's sleeping quarters. This rockery was strikingly similar to the one she found before, obviously crafted by the same hand.
"It seems the entrance to the underground palace is here." Qing Shuang thought to herself as she stepped forward, carefully examining the rockery for mechanisms.
