"I've seen this person, with a woman and a child."
"Just this morning, I bought him slippers, he bought a pair."
Is there a transaction record?
Wang Zhaokai was delighted, "How did he pay?"
"Cash."
Cash?
Then we can't trace any banking information.
"Remember the note?"
"Swap it out."
The small vendor took out a few cash notes, "I only received three 10-yuan bills today, but I don't know which one it is."
"Give them all to me, I'll exchange them for you."
Wang Zhaokai wrapped the three bills with gloves, planning to take them back for Lu Chuan to examine. Perhaps they could extract the other party's fingerprints.
"Did they enter the station?"
"I didn't see them at the entrance, but they headed in that direction."
The direction the vendor pointed was precisely toward the ticket hall.
With a certain target, the follow-up debate and inquiry by Wang Zhaokai brought more clues.
