Please don't stick to Officer Qi [criminal investigation]

"How could it be? I remember it was the day before yesterday." The old man was obviously a little impatient, "Did you make a mistake with your mobile phone calendar?"

This is annoying to everyone.Even Qi Lin felt incredible.

Stealing someone's day is definitely not an easy thing to do.

"No, my calendar also shows that today is NO.20." Qi Lin opened the calendar to confirm, "Do you still remember anything that made you mistake the time? For example, the calendar itself is wrong, or the person watching the news Time slipped by a day."

After Qi Lin's reminder, the old man began to recall something wrong in his life.But after recalling and reminiscing, I couldn't find the reason why I misunderstood the time.

He doesn't usually have the habit of watching the date, and he rarely turns on the TV, so he has no concept of the date at all.

Qi Lin breathed a sigh of relief, but a bigger problem surfaced.

Who killed the deceased?

"Since you don't have the habit of looking at the date, how can you count the date of death?"

"Actually, I haven't counted. After all, the old lady left early, and I'm used to living alone these years. As for the grave sweeping, the cemetery would call to remind me when it was time to sweep the grave. It's just that this year, due to renovations, I can't sweep the grave temporarily. They didn't even call me."

"Does the cemetery also have the habit of repairing?"

"It seems to say that the mole came and kept digging holes in the cemetery lawn to mow the lawn."

"Strange." Qi Lin dragged his chin and thought. The cemetery is not a wilderness. There are hospitals and funeral parlors around it. No matter how you think about it, there should be no animals like moles.

If nature is impossible, then only man can do it.

"Would a salesman as tall as me emphasize something to you?" Qi Lin asked tentatively.

"Of course the salesman emphasizes selling the product. I've never met a salesman who doesn't sell the product."

"That's not what I mean," Qi Lin guided the old man to recall a little bit, "For example, I often mentioned a certain thing to you, or talked about some activities intentionally or unintentionally when chatting."

"It's true what you said. He always encourages me to go out and have a look. Knowing that I like folk music, he also told me that there will be a guzheng performance in the Youth Palace soon."

Qi Lin's eyes signaled Shi Le to look for information about this event on the Internet.Shile soon got the answer from the official website.

"The guzheng performance is at NO.17. I suspect that the salesman kept hinting the time during the period, which led to the mistaken identification of NO.18 as NO.17."

The old man was silent, and seemed to be trying very hard to figure out the relationship.

"Although he did keep emphasizing the time and activities of the event, I didn't use the date to record the time. I clearly remember that it was the day before yesterday. After all, I had to watch the scenery from the balcony every night. I clearly remember that it was only a few days away from today. One night, and last night I saw the two of you talking downstairs."

Recalling this, the old man came to his senses, pointed at Shi Le and said, "Oh, yes, it was the two of you who were downstairs last night. You seemed to be very unhappy, so you went back to your room with a bad face."

As he spoke, the old man felt that something had been mixed up in his memory.

"No, I did see the suspicious person on NO.17. My son called me at NO.17, and that's when I unconsciously noticed the date on the phone. I didn't pay attention at that time. Thinking about it now, It is indeed NO.17."

"That is to say, the salesman hinted that NO.17 was NO.18 that day, making you think that NO.17 was the day before yesterday." Qi Lin made a conclusion. At NO.17, he was still accompanying Shile to discharge from the hospital, so he didn't appear here.Then, the person who appeared below and was seen by the old man must be the salesman.

But at the same time, new questions emerged.

"Then where did NO.18's real memory go? Even drugs can't accurately erase NO.18's memory."

Qi Lin asked himself in his heart, is it really possible to forget the memory of a day?Erase a certain day in a targeted manner, and erase the memory of an old man who can remember even the smallest details.

"Is there such a possibility?" Shi Le put forward his hypothesis, "In psychology, there is such a saying called memory points, which is a way for many people to remember other people. For example, remembering Living in a certain comedian is usually because of his unique humor. Remembering a stranger will also form a first impression through his most special place. Putting this theory in time is the same."

Think for a moment.

"Because the old man's daily life is relatively ordinary, the memory of the date is also relatively vague. But because there are memories in it every day, such as saying something more to the person downstairs, or more than before. The old man played a game of chess, which constituted the memory points of the day. When it is mentioned, it suddenly dawns on him that he has done certain things on a certain date. Similarly, to erase the date NO.18, you need Erase all memory points about this day, so that nothing special happens on this day, and cover up the date NO.18 logically."

Shi Le said so.It sounds simple, but it is very difficult to do.

The old man suddenly realized, "When you said that, I remembered that the salesman did call me every day. But he really didn't call the day before yesterday. He sent a letter to our house, explaining why he didn't call , I read letters in the living room at night, and I went to the balcony very late. Besides, our conversation continued until last night. He clearly said on the phone yesterday: 'Today is NO .19, I'm leaving today' and so on."

"Because of this, you think he will call you every day. Although he didn't call the day before yesterday, he also contacted you through a paper letter. In this way, the rule of contact every day has not been broken. As long as nothing else happens the day before yesterday Things do not constitute a memory point."

"Yes, I'm allergic to pollen. The day before yesterday afternoon, he brought an extra flower with him. Although I quickly disposed of it, I still felt unwell the day before yesterday, so I didn't go out all day."

Sure enough.

A simple but demanding scam.The selected objects must be people who have no concept of dates, and must also have obvious allergies.You need to have easy-to-approach emotional sustenance, and you need to live peacefully. Life itself cannot constitute a memory point.

Tightrope walking.If the old man hadn't added the word "NO.17" when he said the day before yesterday on a whim, this trajectory might not have been discovered until now.

"But why is he, a salesman, cheating me, an old man, like this?"

"His goal is not you. You don't have to worry too much about it. You can live as you want in the future." Qi Lin comforted, "I hope you can forget the previous things, and we will leave the rest to us."
