This is an enclosed underground space, but the corridor is not completely dark; there is a soft white light at the stairway.
As Su Changxing approached, he discovered it was a tube emitting white fluorescence, placed here as a stair light.
"This seems to be something from the little boy's memory. Can it absorb energy from the air and emit light?"
Su Changxing touched the tube, expecting it to feel like plastic, but instead, it felt like marble, cold and chill.

This floor is not the lowest; it is still possible to continue going down.
Su Changxing could vaguely hear a series of miserable cries coming from below, seemingly a woman's scream.
There're still people below.
Thinking briefly, Su Changxing slowed his pace, walking down step by step, carefully perceiving the surroundings, with the pistol already in his hand, ready to act at any moment.
