Xia Lei looked over as soon as he heard the sound. His left eye twitched and everything that was blocking his line of sight disappeared soundlessly. 

The sound was coming from the stairway. The stairway was empty, devoid of people. 

Suddenly, a black cat came out from behind a flower vase. There was a broken branch of a leafy green plant next to the flower vase. 

False alarm. 

The black cat quickly disappeared from view but Xia Lei’s nerves were still tense, and he could not relax. 

There were also broken twigs and dropped flowers on the floor next to the flower vase.

That sound earlier was of the black cat breaking things, and had not been made by a person.

But no matter what the cause was, he was all tensed up and unable to relax. He looked at his watch. The woman who had called him had told him to leave in 60 seconds. Another ten seconds had passed. 

Who was that woman? 

What was the danger that she spoke of? And what level of danger? 

How did she know that he was here? 

How did she know that sort of danger he would be in? 

Should he leave, or follow his original plan and stay here to kill...
