Yao Ran and Long Yu went up to the rooftop, where they stayed for an hour, observing the surroundings.
Once they were sure no one was around, they went downstairs. Yao Ran stored the boxes, and the two of them quietly left the building.
Ten minutes later, six men arrived at the office building. The man wearing sunglasses looked around and said, "Damn it! We are too late."
One of the men turned to him and asked, "Brother, what should we do now? If we return empty-handed, I'm afraid…"
He trailed off, but everyone understood what he meant.
The man with sunglasses clenched his fists and asked, "Are you sure Ling Yi came here to make the transaction?"
The others nodded. "Yes. I overheard him talking to his cousin."
The man could only clench his hands in frustration. After a moment of silence, he said, "He must have known we were following him."
"Should we still follow Yuan Rihui?" Another man asked.
