"Boom!"
Li Xu quickly stepped back.
The dark figure that had been slamming into the door might have been puzzled, wondering why the dilapidated door that used to open with a single push wasn't budging. Consequently, it began to back away.
Sensing danger, Li Xu gestured frantically to the left and right, signaling them to hurry upstairs.
"Boom!"
"Wham!"
A crack formed as the door was pushed open. Debris that had been propping the door spilled out, and a slick, dark shadow appeared in the crack, its oily head beginning to worm its way inside.
Damn it!
This was the kind of mishap that was most feared.
The people on the first floor began to retreat to the second, hearts pounding, proceeding with extreme caution.
The creaking noise of feet on the stairs came again. The dark shadow in the door's crack froze for a moment, then withdrew the head that had already squeezed in.
