Ji Ning's lips curled slightly as she gently pressed the protrusion.
With a light "clack" sound, a small square stone slab popped up from the floor tiles behind the stele.
Behind it lay a metal password panel.
The password panel was covered in a thick layer of dust, suggesting it hadn't been touched in a long time.
Ji Ning pondered for a moment, stretched out her hand, her fingers hovering over the metal password panel, moving slightly in the air, and a series of numbers and letters appeared on the panel's screen.
As Ji Ning pressed the final number, the frame of the metal password panel lit up with a green glow.
Immediately, the tile Ji Ning was standing on started to move downward, followed by a few "clack clack" sounds as a staircase descended in front of her.
Meanwhile, shrill alarm sounds suddenly rang out in several secret rooms in Beijing and Nanling.
Ji Ning had no idea that her action here would alert so many people.
