Chapter 167: Chapter 164: Sudden Change

```

Why was this man so sensitive and anxious? What was that ticking sound coming from his backpack?

Huo Sining's heart suddenly clenched, as she thought of a possibility. She stepped back as if shocked by an electric current, her face turning pale in an instant.

The man had turned his back, but the more Huo Sining thought about it, the more scared she became. She lowered her eyelids to hide the glint of panic in her eyes and bit her lips hard, forcing herself not to look at the backpack behind the man.

After a few seconds, she shakily took out her phone from her bag, paying attention to the man's movements while tremblingly starting to press the keys.

Because the security check-in procedures were cumbersome, the queue Huo Sining was in moved very slowly.

At any other time, Huo Sining would have become impatient, but at this moment, she was screaming inside, wishing the queue would move as slowly as possible.
