The key was inserted into the lock, emitting a crisp sound.
"Clack, clack..."
The key turned, driving several rusty mechanisms to move together, producing a chilling noise.
"Creak—"

"Tap, tap, tap..."
Richard stepped into the chamber. With a "bang," the iron door swiftly closed behind him, leaving not even a crack.
Far from being panicked, Richard was actually quite intrigued and squinted as he surveyed the entire chamber.
He saw that the chamber's area was about three hundred square meters—roughly half a basketball court. The walls were engraved with stones of lighting spells, radiating light and illuminating every corner.
