In the bustling underground of City of Four, within a busy mall.
A Spiritual Ability User, cloaked in a large black robe and shrouded in shadow, walked steadily into an old, empty elevator.
His fingers pressed a series of buttons on the elevator control panel in a specific, unhurried pattern.
Accompanied by a slight mechanical friction sound, the previously silent elevator suddenly let out a low hum, then quickly descended into the depths at a heart-pounding speed.
The darkness swiftly passing by outside the window and the whistling wind in his ears both indicated the extraordinary depth of this descent.
After about half a minute, the rapidly moving elevator finally came to a slow stop.
At this moment, he had already descended hundreds of meters beneath the mall into a hidden, enormous cavern.
The elevator door slowly opened with a "ding," and a suffocating mix of sweat, spices, and an indescribable fervor, along with a deafening noise, assaulted his senses.
