"Who's there?" Ye Anan asked, but no one answered.

She rubbed her eyes, not believing that she had been mistaken, but she looked up at the staircase, and there was no sign of her.

Ye An'an's heart lifted, if she was not mistaken, someone did appear on this floor just now?!

But why did the figure not move at all, and disappear so quickly?

Ye Anan asked twice in a row, but no one answered, driven by doubts and curiosity, he finally walked towards the staircase with his coffee.

The staircase is some distance from her office, on the side of the building, it is also used as an emergency exit, seeing that she is approaching the staircase step by step, Ye Anan held her breath, her heart fluttered, and an inexplicable sense of tension enveloped her......

Because the staircase, which is used as an emergency exit, is rarely used by people, the lighting at the staircase is touch-sensitive, and at night, it is even darker.

Ye An'an rarely comes here usually, and when she just walked to the staircase, she really felt a cold wind coming towards her, thinking that the cold wind she felt in the pantry just now was also blowing from the entrance of the building.

Ye Anan shivered coldly, waited for the induction light to turn on, looked down, and saw that the corridor was empty, and there was no one in sight.

Could it really be her delusion just now, no one passed by on this floor?!

Ye An'an secretly wondered in his heart, if someone really came up, he probably wouldn't take the stairs, but would take the elevator directly!

Ye Anan shook her head and laughed self-deprecatingly, probably because she had been working at the desk for too long just now, and she was dazzled and had an illusion!

Just as she turned around and left the staircase, the window at the corner of the corridor suddenly made a violent cracking sound, and Ye Anan looked back and saw glass shards scattered all over the ground.

Ye Anan went downstairs along the steps, looking at the glass fragments on the ground, he really couldn't imagine that the wind at night was so strong that it could blow through the entire glass window.

It seems that tomorrow it is time to find someone to repair this window, Ye Anan thought silently, and a violent crash sound came from downstairs again, as if something was hitting the door fiercely.

Every impact made Ye An'an's body inevitably shake, she took a deep breath, and was about to call the security guard downstairs to ask what happened to the security guard, but found that the mobile phone was not with her.

Ye Anan had no choice but to go upstairs to her office, planning to make a call to the security room downstairs first, but just as she was about to go upstairs, the lights in the stairwell suddenly went out.

The sudden darkness made her unable to adjust for a moment, so she could only fumble her way to the wall, trying to touch the sensor light's controller, but no matter how much she tried, the stairwell lights stopped coming back on, and the violent impact never stopped, and it was getting closer and closer to her.

Ye Anan could only grope her way upstairs with her own feelings, and the sound of impact suddenly stopped, and she didn't have time to breathe a sigh of relief, and the next moment a low laugh and gasp followed.

The same strange wheezing sound that seemed to be all around her, as if she had heard it alone in the elevator that night, sounded so oozing in the dark night that she couldn't see her fingers out of sight, and made the hairs stand on end all over her body.

Ye Anan didn't want to stay here for a long time, she boasted of her boldness, but she felt that in this dark environment, she was like a lamb to the slaughter.
