The lights were on, so I could see clearly even when the door was closed. I'm sure the customers are conscious, because no one will see the door closed and burrow inside. I looked at the ceiling again, except for something hanging that looked like a water pipe, which was supposed to be connected to the fire alarm. But other than that, I didn't find any camera gear in this area.

For fear of oversight, I asked Mr. Yang, is there no surveillance camera in this area? Teacher Yang said that there was originally a camera that could capture this area, but after the fire door was closed, it was blocked, and you can do it boldly with confidence. I said to him again, is it possible that you can retrieve the surveillance video when you first hit a ghost in this place? Teacher Yang said that in fact, they had already watched the video long before we came, but because of the angle, they only captured the picture of the staff poking their heads to find the ghost, but they were not able to shoot the ghost. After speaking, Mr. Yang pointed to a shelf a few meters behind me and said, judging from the picture, the ghost should have appeared behind this shelf at that time, but there was no one on the picture, it was blocked by this shelf.

I was a little disappointed because I had less chance of finding evidence. This enclosed area is about 100 square meters, in order not to miss any point, I said to Hu Zongren, if I measure such a large area by myself, it will delay a lot of time, will you come with me? Hu Zongren nodded and said yes, so the two of us stood in two opposite corners, started to measure in opposite directions, and gradually narrowed the range, so that the time was saved by at least half. So for nearly an hour, in addition to the sound of the freezer that roared from time to time, we also heard the occasional churning of fish in the water in the aquatic area. When I met Hu Zongren, both of us didn't seem to look very good.

Because in this half of the area I inspected, I found traces of ghosts, not only under the shelves, but even on many vegetables. And the vegetables here were all just distributed this morning, which means that at least after the distribution was completed this morning, there were ghosts here. And what struck me the most strange thing was that I found a few carrots scattered on the ground under a pile of cabbage shelves. The carrots are damaged to varying degrees, because almost the top of the place, there are some drops. The section that fell was fresh and watery, which means that it happened today, and I also found a pile of carrot residue on the ground.

This almost ruled out the possibility that the rat was the mouse, because even if the rat ate the carrot, it would not spit on the ground, but swallowed it in the stomach. I also took a closer look at the part of the upper section, and it was a little smaller than the average person's tooth marks, but it was obvious that they were human tooth marks. So when the ghost started chewing carrots, it was actually just repeating the action of eating, and it didn't really eat into the stomach, as evidenced by the scraps on the ground. Moreover, on each carrot, there is a stronger agile reaction compared to the surrounding one.

I counted more than a dozen shelves, and there were basically a little stronger agility under each shelf, indicating that some ghosts had been here longer than outside. It's just a very simple calculation problem, and years of experience are enough for me to come up with this judgment. What puzzled me was that in addition to the shelves described by Mr. Yang at the beginning, even the raw meat area, the aquatic area, and almost every corner also found traces of ghosts, except for the water, which was the only location I could determine without inspection. Hu Zongren's inspection situation is similar to mine, we can't climb up the ceiling, but if we climb up, I'm sure we can find a lot on it. In general, the situation in this area is more serious than Mr. Yang's office, and it is simply a place for a group of ghosts to revel. Maybe it's an exaggeration, but seven or eight ghosts, there's always something here.

I discussed with Hu Zongren for a while, and I told him that in this part of the area I inspected, in addition to the places just mentioned, I also found a smart movement near this drainage ditch, which is much stronger than the surrounding area, so if possible, we have to consider that this drainage ditch is probably a passage for ghosts to enter and exit. Hu Zongren nodded, and then told me, I found some at the door over there, the flames were running around, looking very excited, and they couldn't be blown out, that place should be very strong, and then you can use the compass alone to look there, and compare it with what you see a little, and we will be able to have a rough beginning. I asked Hu Zongren, where is the door? Hu Zongren turned around and pointed to the wall opposite the fire door, a place where a lot of cardboard boxes were piled up around and said, that's it, there is a button, it should be an elevator. At this time, Mr. Yang answered and said, yes, there is the elevator where we load and unload the goods, this is the fresh area, and they are all transported directly from the warehouse on the ground floor by this elevator.

I took the compass and walked to the elevator door, which was an old-fashioned elevator with green skin, and the door was folded and closed, which is very rare now. I crouched down and checked around the elevator to rule out any interference from the electromechanical products, and the reaction was by far the strongest I had detected in the area. This was undoubtedly a very significant discovery for me, and at least ruled out the possibility that I had previously thought that the ghost had entered through the gutter.

But a new problem has arisen, if it is a long-term haunting here, presumably Mr. Yang and they will not be the first people to find out, and someone must have noticed it long before that staff member. So I hurriedly asked Mr. Yang, how long has this supermarket been here? Because I saw that the surrounding walls were not newly renovated, and it looked like it had been at least a few years. Sure enough, Mr. Yang replied to me that this place has been open for nearly 5 years, and he is one of the first batch of employees, and he has come to work here shortly after graduating from university. I asked him again, had anything strange happened in the supermarket before this incident? Teacher Yang thought about it carefully and said, it really didn't happen, it has always been calm, and there has been no abnormality at all.

Then it shouldn't be, if the ghosts in the same place suddenly burst out in a certain period of time, it must be a trigger, or it was a bad drug by a peer, relatively speaking, the former is more likely, so I told Hu Zongren my guess, and told him that if we want to understand this, we must find the cause of this incident.

Teacher Yang came over and said, why do you want to find any reason, can't you just do it directly? That's what I watch on TV. I glanced at him, in fact, I didn't blame him, I told Mr. Yang that those on TV can indeed do this, but that has never been our style of doing things. We are not so bored that we have to get to the bottom of everything, but solving the problem from the root is once and for all, otherwise it will always be a symptom rather than a cure.

After speaking, I pointed to the other side against the wall, there was a small closed door in the fresh food area, and I asked Mr. Yang, what is behind that door? Teacher Yang looked at it and said that there was a cold room, where the frozen foods such as pork and fish were stored, and the crushed ice on our shelves was also made from it. I asked Mr. Yang, can you open it and let us go in and have a look? Teacher Yang said that there was no way to do this, and he didn't have the key to the door, but if we needed it, we could call someone to help open the door. I walked to the door again, lowered my body and checked the compass in the crack of the door, the cold air came out of it, and the reaction on the compass was not strong, it was similar to the reaction in the environment, which meant that the ghost did not enter here, and if I did, at least I should be able to find a stronger reaction in the crack of the door than around. So I told Mr. Yang, no, this place has also been excluded.

In this way, in addition to the carrots under the shelves and those carrots that appear inexplicably, the elevator is the most likely to be entered and exited by ghosts in this area. Ghosts actually take elevators, but there is no reason to say that they take the elevator themselves, because some ghosts will follow the path of their own life, and things like elevators have not been used for too many years, so it can be preliminarily judged that these ghosts will not die for a long time, at least after the large-scale use of elevators began in China.

I went back to the middle of the house, picked up a green onion, and drew a rough picture of the terrain on the ground, and there was dirt on it, so I used it as a pen. The elevator leads to the warehouse on the first floor, and the entrance to the first floor can be seen directly outside the window of Mr. Yang's office, the stairs outside the office, there is a brazier between the first floor and the negative first floor, that is to say, if you go down the stairs, you can also reach the negative first floor, all the clues currently mastered are overlapped to the negative first floor, do I have to go to the warehouse on the negative first floor to check again? Isn't there anything else in common?

As I painted, I seemed to suddenly think of something, I asked Mr. Yang to come to me, I pointed to the marks on the ground that I had formed after dipping the soil in the water and asked him, is the black mark you saw on the mobile phone and desk in the office that day, is this the color? Teacher Yang frowned and said, it should be a little darker, I reached out and wiped it on the ground to let him smell it, is it such a smell, because of the smell of green onions, he said that he can't smell it, but it is a lot fishy.

At this time, Hu Zongren uncovered the net on the top of the drainage ditch, reached out and picked a little black mud from it with his fingers, and sniffed it, showing an ugly expression, and then asked Mr. Yang, take a look again, is it such a color? Doesn't that taste like this?

Teacher Yang leaned over and smelled it, and said categorically, this is the smell!
