After a few seconds of silence, a long beeping sound came from the phone. Song Qing was stunned.
The phone rang again, and the sound was accompanied by a slight fluctuation of electric waves. It wasn't until the phone rang four or five times that it was picked up.
"Who is it?"
On the other end of the phone came a deep male voice. His tone was a little cold. The moment he spoke, song Qing felt a cold wind blowing from the back of her neck. It was as if someone was pressing against her back and letting out a long breath. The hair on the back of her neck stood up.
Before she could reply, she instinctively stood up straight, subconsciously touched the back of her neck, and raised her head.
There was a groove in the ceiling against the wall. It was the outlet of the central air conditioner, and cold air was blowing out slowly.
