At this time, they were only three floors away from the top floor.

The six of them suddenly slowed down, and their expressions became more cautious and alert, and they walked upstairs with careful steps.

He Zizhen listened to the movements upstairs while holding the wireless intercom in his hand tightly, waiting for news from Yun Zhou at any time.

However, there was no sound from Yunzhou. The group of them walked up two floors carefully, and there was only one floor between them and the top floor.

But at this moment, a few crisp sounds of "kick" suddenly came from the upstairs, which were clearly visible.

Lin Yu and others paused, their faces changed in an instant, and their eyes gathered on He Zizhen's face, as if asking what He Zizhen's voice was.

"It seems...it's the sound of high heels..."

He Zizhen said hesitantly, and he felt unbelievable.

How could such a crisp sound of high heels come from such an abandoned high building?

Lin Yu and others also had their faces changed and their eyes were surprised. In fact, they could hear the sound very much like the sound of high heels upstairs that they often hear at home, but it was a bit incredible to hear this sound in this situation.
