In this county called Lanfeng County, there are only four business halls.

Although Wan Yao helped Lin Kun confirm that the black card came from this county, she did not specify which business hall it was.

Now Lin Kun is in the family he chose at random.

Generally, the phone card is sold, and there will be a record in the business hall, and you can check it with the computer to know whether it was sold from here.

After getting the boss's cooperation, it only took three minutes for Lin Kun to learn that the card was not from here.

There was no need to stay any longer, and he went to the next business hall without stopping.

It's still the old routine, showing detective evidence, "brushing face", making up stories, and easily gaining trust.

This time, the staff gave him a very positive answer, and the card came from this business hall!

However, so much time has passed since the old man bought the card, and it is impossible for the staff to remember what the person who bought the card looks like.

Fortunately, this kind of business hall usually has surveillance cameras, and with the permission of the boss, Lin Kun plans to start viewing the surveillance video of the day the card was sold on the computer in the store.

But God does not fulfill people's wishes, the surveillance video of this business hall is generally cleaned once every half a month, and the last time it was cleaned was five days ago.

estimated the time, the time when the old man bought the card, it should be half a month ago.

In other words, the video content of the day the card was sold has long been gone.

The clue seemed to be broken like this, but Lin Kun did not have the slightest loss on his face, and came to the outside of the business hall, looking left and right.

It's all said, in this day and age, there are surveillance cameras everywhere.

Looking around, Lin Kun found that there were two places where surveillance cameras could shoot at the door of the business hall.

They are the surveillance camera in front of the hotel located across the street, and the surveillance camera in front of a supermarket located on the left side of the business hall.

Lin Kun went to the supermarket first, and still used the same method, and after gaining trust, he learned that the supermarket's surveillance video was backed up, so he didn't have to worry about being cleaned up at all.

It didn't take long for him to see the supermarket's surveillance that day.

The location of the surveillance camera is located on the right side of the supermarket, so you can not only see the entrance of the supermarket, but also the scene at the entrance of the business hall next to it.

In terms of clarity, it's not bad, at least there's no problem at all with seeing people's looks clearly.

According to the records of the business hall, the card was sold at 12:40 p.m.

Lin Kun pulled the progress bar to 12 o'clock, and then started watching at twice the speed.

As time passed, one figure after another passed by the door of the business hall, but no one entered the business hall.

When the time in the surveillance video came to 12:30, a figure appeared outside the door of the business hall, Lin Kun's eyes narrowed slightly, and he immediately froze the picture.

This is a diminutive old man, who looks less than 1.6 meters tall, dressed in an extremely old-fashioned manner, and at first glance looks like a peasant facing the loess with his back to the sky.

But his back was straight, his head was slightly raised, as if he was born superior, and a strange sense of contrast arose.

"Finally...... Found you. The corners of Lin Kun's mouth rose slightly.

He was not surprised that this person had come to the business hall to buy a phone card in person.

It is not difficult to see from the fact that this guy bought the water army to spread the advent method on the Internet that he is by no means a pedantic antique.

As a resentful spirit descending from the underworld, he was obviously extremely strong, but he did not threaten Fei Yuanjie, the leader of the navy, by force, but bought it through money.

It is not difficult to see that this guy has no habit of abusing his power, and after attaching himself to a peasant, he did not even change his clothes.

It shows that this guy is mature and doesn't care about other people's eyes.

But none of these can hide the arrogance of the other party.

As a member of the advent group, this guy is so strong, for ordinary people, he is like a fairy.

With his identity and strength, if he has to be sneaky and find someone to buy a calling card on his behalf, that is really funny.

learned about this guy's appearance, but Lin Kun couldn't continue to ask Wan Yao for help.

Even if it is a policeman, it will not have a good impact if he investigates other people's information privately.

It's okay once or twice, Lin Kun has done this again and again, if it weren't for Wan Yao is the daughter of the director, she is extremely beautiful, and her popularity is good, it would be impossible to help him so many times in a row.

Last time, after Wan Yao helped Lin Kun investigate the origin of this calling card, he had already begged him not to ask himself to help investigate these inexplicable things.

Now that the society is so turbulent, the police are basically working all day, and they are so busy that they really don't have time to help him investigate.

There is no way, Lin Kun can only rely on himself, it is not a difficult thing, it is just a little troublesome.

took a few of the clearest pictures of the old man in the video, sent them to his mobile phone, and then left the supermarket.

……

Three hours later, Lin Kun successfully investigated the identity of the old man.

The process is not difficult, just a little troublesome, with his ability to add the little black cat, he has long been able to enter and leave the police station at will.

Using the illusion of the little black cat, Lin Kun quietly entered the county police station in Lanfeng County, and spent a lot of effort to find a police officer who specialized in investigating this area.

Then it's time for the little black cat to act, using illusion to let the police officer see the scene where the police chief personally comes to help him with the investigation.

Moreover, the "chief of police" also specially told him that this was a private case and could not be disclosed to others.

The little police officer naturally did not suspect anything, and quickly investigated the identity of the old man in the pictures according to Lin Kun's pictures.

Of course, if Lin Kun used force, it would be far from so troublesome, just a direct threat of violence.

But it is not a wise choice to save a little time and bring unnecessary trouble to yourself.

The old man's name is Peng Dahai, 60 years old this year, a native of Sankou Village, Lanfeng County, born as a farmer, and he is still alone.

There is a high probability that this person is not in Lanfeng County now, after all, the same place does not need two members of the advent group.

This should belong to the previous Mei Yishan's action territory, and Peng Dahai should have left here a long time ago.

However, Lin Kun still planned to go to the other party's house to see if he could find any useful clues, and then think about how to continue next.

According to the local population, Sankou Village is not far from the county seat, only a few kilometers away, and you can take the No. 139 bus to go directly there.

Of course, Lin Kun didn't bother to wait for the bus, so he called a taxi out of the county.

About ten minutes later, I heard the driver greet "Sankou Village has arrived".

He gave the money to get out of the car and looked around the straight road, all lined with rice paddies.
