The owner picked up the handkerchief, looked carefully, nodded, and said, "Yes, it's our store. It was given as a gift in December last year."

"Well, how many were given away at that time?"

"Well, because Christmas is approaching in December, there are many people coming to the gift shop to shop. Roughly speaking, there should be about 200 handkerchiefs for you. If you spend 50, you will get a handkerchief."

The handkerchief is really good, but the color is also quite monotonous. Zhang Borui thinks that the owner seems to be too stingy. However, it seems that this store is also operated by a small business, and if the gift cost is too high, it is really unpaid.

But Huangfu He frowned slightly, and Xia Xiaomei was also very anxious.

How do you check so many people? The shop owner cannot remember every customer’s face, right?

Zhang Borui took out a handkerchief from his pocket and handed it to the shop owner, saying, "I'll ask you... the person in the photo, have you ever been given a handkerchief for buying things?"

"Well, let's take a look." The owner took the photo and said, "This person..."

The person in the photo is naturally Zhang Boling.

"I don't remember it. How could I remember so many customers at that time? Is there anything you guys?"

It's true.

Huangfu He suddenly asked: "Do you usually issue invoices to customers?"

"Invoice? No, usually only one receipt will be issued. Most of the people who come to me to buy gifts are given by private gifts or for themselves, and there is no need to reimburse the public. How can I need an invoice?"

“Are the receipts usually issued only when the customer requests?”

"It depends on the situation. I will not take the initiative to ask customers whether they want receipts. There are not many customers who ask for receipts."

It would be very troublesome if there was no invoice or receipt. Otherwise, if such a voucher could be found in the home of the deceased, it would also be proved that he had indeed purchased something here and received a handkerchief.

However, judging from the fact that most of the deceased have come to Baiyan District, it is very likely that all six people were shopping in this store and then given a handkerchief.

"Does your handkerchief... have any special functions? For example, as an amulet, seek good fortune and avoid bad luck..."

"Ah?" the owner was stunned and said, "You are kidding, sir, we are a gift shop, not a temple or Taoist temple. Besides, there is no way to use handkerchiefs as amulets."

Huangfu He thought about it and it seemed that he could only hand over the handkerchief to Murong Shen and let him find a way to check the fingerprint on the handkerchief.

In addition, has Bai Jing come here to buy handkerchiefs? If you come here, you may have bought some gifts here. You need to check whether she has given her gifts to her classmates during Christmas, or whether she has more jewelry on her body. If it is confirmed, then perhaps Lan Qi was killed because she got Bai Jing's handkerchief.

Next, we will go to Red Star Mall and investigate.

On the other hand, Yin Ye and Yin Yu came to the place they agreed with Wu Zhenzhen, in a small park near her home.

Wu Zhenzhen’s parents were going out to work at this time, so she could get out.
