Zhou Ning nodded.
"...That's the situation. We've located four vehicles of the same type, though we still need you to confirm them later. However, Zhang Hongwei was in the textile district on the morning of October 20th, and in the afternoon, it was him who picked up Fu Chunyu. So his suspicion has increased.
