Certainly, here's the translated text:

The black building has about seven floors.
Its total height is approximately thirty meters, meaning each floor is about four meters high!
Obviously, there is a large robot inside this building.
Liang Yuan silently approaches the building, weaving through the empty shadows and entering inside.
However, just as he steps into the building, an alarm suddenly blares throughout the entire structure!
"Beep—Beep—"
"Alert! High-energy creature intrusion!"
"Alert! High-energy creature intrusion!"
"Alert! High-energy creature intrusion!"
Thud thud thud—
Following this, the sound of numerous footsteps echoes, resembling metal striking against the floor.
Immediately, the entire building is illuminated with black lights, sealing all exits and entrances.
The walls also reveal a faintly blurry energy shield!
Liang Yuan raises an eyebrow, somewhat surprised.
"Detected even in shadow form?"
