Ominous Premonition

Taking out his phone to have a look at it, he noticed that it was an unfamiliar number. Such occasions had happened several times before, so Zhang Lisheng casually picked it up without a care. Just as he expected, a deep voice resonated from the phone. "Sir, I'm the FedEx delivery guy. Your parcel has arrived."

"11.57pm." Zhang Lisheng looked at the time. "I know your voice. Very good, 'deliveryman', you're not late. Please wait a moment, I'll go downstairs immediately."

Now that the new 'materials' had arrived, it made him a little excited. The young man opened the door and walked out of his glass room. Most of the people in the lab worked throughout the night but nobody noticed his actions at all.

As he walked down to the foyer through the stairs, Zhang Lisheng saw two strong and brawny men wearing FedEx uniforms while chatting to a night guard and a skinny young man carrying two big sling bags.
