However, after this investigation, Master and I have come up with some patterns: people who are sick are people who have had the experience of going home in the middle of the night. Some specialize in evening business, and some often work night shifts, and they often stay up late. The eighty-year-old man usually likes to play mahjong, and sometimes he goes out to play until after twelve o'clock at night before returning home. Sixteen-year-olds, who had dropped out of school and had not found a job, would occasionally run out to find an Internet café to surf the Internet, and would play until the Internet café closed at 2 a.m. before returning. The little couple didn't have the habit of staying up late. But under my master's questioning, they were embarrassed to admit that they had gone out to sing K the night before they got sick, and when they came back, they lingered at the door for a while before entering the house. Boss Tang was depressed, and went out to have a drink with friends a few days ago and got drunk. He lay down at a friend's house until the middle of the night before he came back by himself.

In this way, the master concluded that the problem was probably in the alleyway, and these people should have been walking in the alley in the middle of the night.

When I arrived, Master asked Boss Tang not to follow, so he took me for a walk in the alley. The alley is not long, only about a hundred meters, and the innermost part is a dead end. There are only three street lamps in the alley, one in front and one in the back, and in the middle, each about fifty meters apart, so the light is a little dark. The alley was less than two meters wide, so there was no debris piled up in front of the door, not even potted plants. If there is a ghost, where will it hide?

I followed Master from the end of the alley to the end of the alley, and then from the end of the alley to the end, and carefully checked back and forth twice, but I found nothing. On the third trip, the master suddenly stopped, and frowned expectantly, as if he had noticed something. I also looked around, but I didn't see anything wrong. However, my gut tells me that there is something wrong with the atmosphere around me.

Master watched for a while, and then continued to walk into the alley, but I still followed him. As I walked, the feeling that something was wrong still came and went, looming out of nowhere. Then for a moment, I felt as if someone was following me, and it was still close!

I jerked back and found nothing behind me but my shadow. I went to look at the houses on the left and right, one side was No. 11, and the other was No. 14. But by this point, the doors of both families had been closed, and even the lights in the windows had been extinguished. I looked up again, and there was a row of wires overhead, but there seemed to be an unusually shaped black shadow attached to it.

Master also stopped in front of me, turned his head and asked me, "What's the matter, have you found anything?" ”

I pointed to the top of my head and replied, "There seems to be something up there." ”

Master came closer and squinted his eyes to see, but he couldn't see what was on it. I took out my phone, turned on the flashlight, and took a picture of it, and the shadow seemed to have wings, it could be a small bird or a bat, or it could be a larger insect.

Master picked up a pebble from the ground and bounced it at the shadow. It seems that the master has also practiced this trick, and the gesture of playing the stone is exactly the same as what Boss Su taught me, and the stone was thrown very accurately, and it directly hit the black shadow. But the shadow only shook for a moment, but it didn't fall, and remained in place.

The master said, "It shouldn't be a living thing, I'm holding you, you reach out and take it off." ”

To be precise, that row of wires should be network cables, telephone cables and other optical cables, which are not electrified. I reached out and felt the height, about three meters, maybe I could get it. Master made me stand up straight, reached out and grabbed my calves, and lifted me up.

Sizzle! Master's hands are so cold!

I could feel the chill through my trouser legs. But tonight the temperature was already low, and we've been wandering around here for a while now, probably freezing. I stretched out my hand and pulled the shadow off as soon as I could reach it.

Hi! It turned out to be a paper crane!

The paper crane was folded out of red paper, just sandwiched between two wires, and I don't know which bear child threw it. The buildings next to it are all two or three stories high, and it is easy to throw them up. Master took the paper crane apart and looked at it, but it was just a solid piece of paper, without any pattern. It's been a long time, but the problem is not on this paper crane.

So the master and apprentice continued to walk forward, and by this time they were almost under the street lamp in the middle. Master was still walking in front, and I was following two or three paces behind, basically walking in Master's shadow. But my uneasiness grew stronger, and every now and then I had to look back to see if something was following me.

Alas, no!

I suddenly wondered again and stopped. Why is it that Master has only one shadow, but I seem to have two? I looked back at the ground, and sure enough, there were two shadows behind me, about 30 degrees apart!

Is it a matter of light source, if there are two light sources nearby, two projections will be produced when it hits me. But I looked up and saw that the three street lamps in the alley were still far away from each other, and there were no porch lights next to them, and the closest light source to me was the street lamp in the middle.

I tried to wave my hand, and the two shadows on the ground waved together, and the movements were very consistent. I shook my head again, and the two shadows shook their heads together. I did a more complex stretch, and all my limbs moved, and the two shadows were done effortlessly and accurately, without any stagnation or inadequacy.

I walked over to Master's shadow again, trying to compare the angles to see which shadow was off. But what makes me laugh and cry is that my two shadows actually sandwiched my master's shadow in the middle, as if the master came out of the two identical me!

Master also saw that there was a problem at this time, so he stood aside and watched me make movements. But he didn't say anything, and prompted: "You jump, jump!" ”

I understand what Master means. When I was standing on the ground, both shadows were attached to my feet, and if I jumped up and left the ground, it stands to reason that the two shadows should be detached from my feet.

I jerked up so hard that the two shadows were out of my foot, and I couldn't tell which one was problematic. But at first glance, I still think something strange and unreasonable. So I jumped again.

Damn, there's a problem!

When I jumped, the feet of the two shadows were separated from mine, but the feet of "theirs" were connected!

The master said, "No need to jump, let's go to Boss Tang's house again." ”

We knocked on the door of Boss Tang's house. He hadn't slept yet, just surprised why we were back. When you enter the house, there are more light sources and shadows are scattered, both in front and behind, on the left and right. I counted them carefully, and the number of shadows under my feet was the same as Master's.

Master nodded knowingly, "I didn't follow up, it doesn't like bright places." ”

Boss Tang couldn't understand what we were talking about, so he asked if there was any reason?

Master said: "Boss Tang, if you want to find out about this matter, you may need to cooperate." ”

"How to cooperate?"

"You go out into the alley, walk around the alley, walk to the alley and come back. Go under the street lamp in the middle and stop for a while, you can do anything there, but you have to stop for half an hour. Master explained.

Boss Tang felt inexplicable about my master's request. He asked why he did this.

The master didn't explain, so he said, "We're going to do some experiments, but don't worry, there's no danger." ”

Boss Tang looked puzzled, but he still put on his clothes and went out. Master and I went up to the balcony on the second floor to hide, peeking through the crack in the railing to see how Boss Tang walked.

Boss Tang walked out of his house and walked in the direction of the alley. We paid attention to it, and at first there was only a shadow behind him. As Boss Tang walked past the street lamp in the middle, the projection angle of the light source changed, and his shadow ran to the front, but there was still only one. At this time, the "ghost" should not have followed him.

Boss Tang walked to the alley and turned back, it was far away, and we didn't see whether his shadow had changed. It wasn't until he approached the street lamp in the middle that we clearly saw another shadow behind him!

Master told Boss Tang to stop under the street lamp for half an hour, so he walked there and stopped, but he didn't know what to do, and looked around for a while. It was still quite cold outdoors late at night in winter, so Boss Tang really had nothing to do, so he took out a cigarette to smoke, and put both hands in his coat pockets to keep warm. His whole body shook under the street lamp, and the two shadows behind him also trembled.

About halfway through the cigarette, one of the shadows finally changed!

The shadow on the left didn't follow Boss Tang's movements anymore, but quietly pulled a hand out of his coat pocket, stretched out his hand to the right shadow's ear and broke it, and even broke off the left ear of the other shadow, and stuffed it into his mouth to chew!

Boss Tang also seemed to sense that something was wrong, but instead of looking back, he raised his hand to rub his left ear, as if he was numb from freezing. The true shadow of the missing ear behind him still followed his movements, but the missing ear was missing there, and it was not restored. The fake shadow that ate the ear also hurriedly followed Boss Tang's movements, but it was still a small delay in the rhythm.

Seeing this, it should be clear which is true and which is false. I looked at Master and wanted to ask him what he was going to do next.

Master compared his fingers to his lips, but motioned for me to remain silent and to continue observing.

After Boss Tang finished smoking, he threw away the cigarette butt and began to stomp his feet and rub his hands again, as if he was feeling a little impatient. But he took out his phone and looked at the time, but still didn't walk away, continued to stand under the street lamp, and took out another cigarette to smoke.

After a few more minutes, the fake shadow behind Boss Tang moved again. It reached out again, this time with its left ear.

At this time, the master suddenly stood up and shouted on the balcony: "Boss Tang, it's too cold outside, you hurry back to the house!" ”

Boss Tang agreed, threw away the cigarette, and trotted all the way back. The fake shadow behind him was interrupted by the master like this, so he quickly stopped his movements and returned to the same with the other real shadow.

I followed Master and quickly went downstairs, waiting in the corridor for Boss Tang to come in. Boss Tang kept shouting that it was cold, and he was still shivering when he entered the house. I went up and looked closely, and there were as many shadows as mine, and the left ear of each shadow was not missing.

Master asked, "Is your left ear numb?" ”

"Hemp! It's so cold outside! Boss Tang subconsciously reached out and rubbed his left ear again, wanting to warm up.

"And what about your right ear?" Master asked again.

Boss Tang also touched his right ear and said, "Well, it's okay here......"

Master nodded and said, "Okay, we probably know the reason." We're going to go back first, and the guys who are ready to do the work will come and deal with it. ”

Boss Tang wanted to ask what was going on, but the master just refused to say, and only said, "The secret of heaven must not be revealed!" ”
