After class, I carefully collected the red liquid in the test tube into a small flask and secretly put it in my school bag. After school in the afternoon, he went directly to Uncle Li's house and wanted to ask Uncle Li if he knew what this thing was.

Uncle Li took the small flask with the red liquid, looked at it carefully for a while, opened the cap, and sniffed it. "You got this thing from there!" So, I told Uncle Li about what happened in the real yàn class. After listening to this, Uncle Li smiled and said, "It seems that there must be something wrong in this room." ”

"Oh, there's a problem, and you know what it is?" I looked at the flask with interest.

"Hehe, the red thing in this is called blood, whether it is the color or the smell, it is very similar to blood, but its essence is still the liquid that you get by doing it, and it is only after certain means that people will feel that it is very similar to blood. ”

"Huh, you're saying it's not red, it's something wrong with our senses?"

"Yes, you can understand it this way, in fact, the external things that we perceive are very different from the actual ones. Flowers are red, grass is green, these are the information we get through our eyes, and this perception ability is affected by many factors in the space we live in. The qiē around us is actually composed of different forms of the five elements of metal, wood, earth, water, and fire, and the changes of guò over hundreds of millions of years have formed the current environment, and our perception of the qiē objects around us is formed under this environment and aura. Got it?"

"I don't really understand, you said it too fast...", I scratched my head and looked at Uncle Li.

"Let's put it that way. Uncle Li thought for a while, "Take the yellow paper that your eldest brother usually uses to write symbols, you usually see that it is yellow, if you put it in blue light, what you see is black instead of yellow, you should understand." ”

"I've seen this, and now I kind of understand that a thing may see different things in different environments, and our feelings about everything around us are actually shown under the current aura of the earth, if we change the aura and environment, then it may not be the way it is now. ”

"Yes, that's what it means. Uncle Li smiled and nodded, looking at me very happy, this kid is really thorough.

"Then the contents of this bottle are actually blue copper hydroxide (copper sulfate and sodium hydroxide produce copper hydroxide and sodium sulfate), but someone has changed the aura inside and made us have an illusion. ”

"Yes, but it's not necessarily that people have changed the aura in it, the phenomenon you see is called ghost blinding, and most of it is done by the yin spirit that stores zài in another dimension. "Uncle Li looks very mysterious.

"Ah??

Looking at my expression, Uncle Li smiled, "What's so strange about this, in fact, there are a lot of yin spirits around us, it's just that they don't usually disturb people's lives, since in the real yàn room, there are yin spirits interfering with you, there must be a reason, from what you just said, it seems that which yin ghost is just interested in which girl, it means that there must be some kind of connection between them!"

"No~~~, which Sun Li is just a high school student, which yin ghost likes her?"

"Fart, like her to scare her every day? Usually ghosts haunt people who have enmity with people, young man, do you like her?" Uncle Li laughed after speaking.

"Don't talk nonsense. I blushed. "What then? Which ghost will hurt which classmate?"

"Hehe, maybe, if there is a deep hatred between them, it will not only hurt her, but also may kill her. Uncle Li then said with a wicked smile: "You care about her so much, it seems that you really have a little interest in her!"

"Don't talk about those useless things, I haven't spoken to her, but since I met it, I should help. ”

"Yo, the young man really has a chivalrous heart, hehe, that's right, as long as there is such a thing, we must take care of it, tomorrow you take the compass and go to the real yàn room to test it to see if there is a problem with the wall." ”

"Okay. "I'm like a warrior in battle, full of fighting spirit.

The next day, I rushed to school early with my compass. Compass, in fact, is a compass, according to legend, it is the emperor of the war Chi You, his prime minister Feng Hou developed, initially only marked with the direction, and then from Yang Junxiang to create the heavenly plate, Lai Buyi created the human plate, it formed the most basic heaven, earth, human three layers of the compass, and then the various sects according to different uses, and added the corresponding things on it.

I use a four-layer compass, the chassis is a square, which represents the earth, and the middle is a circle, which represents the sky, and the heaven is round. The place where the compass is placed is called Tianchi, one end of the compass is like a pair of calf horns, referring to the north, and the other end is the compass, the red place on the compass indicates auspiciousness, and the black place indicates danger.

In the early morning, the campus is very quiet, only three or three boarding students are reciting words on the playground and under the big trees. I locked my bike and went straight to the real yàn room at the back of the school building.

It was very deserted in front of the room, and there was no one left. Although the weather in October was warm, I immediately felt a chill as soon as I arrived. The door of the room was locked, and I looked through the window, it was very dark inside, and all kinds of real equipment were lying quietly on the white real yàn table. I took out the compass, flattened it on my chest, measured it from the outside, it was normal, and walked to the door of the real yàn room, looked at the direction of the door, and there was no problem. Since the door was locked, I couldn't get in, so I had no choice but to wait for class to find an opportunity to test inside, so I put away the compass and walked towards the teaching building.

In the afternoon, there is a physics class, which is also conducted in the real room. Due to the large number of people in class, I never had the opportunity to measure the room with a compass. When class was about to end, I secretly pulled the latch of a small window open, ready to come in through the window after school to probe the situation in the house.

"Bell!" After class, I took the initiative to help the teacher clean up the room, and finally watched the teacher lock the door, which was reassured. After school in the afternoon, I waited for a while and saw that my classmates had basically gone home, so I came to the real yàn room and jumped in through the window gently.

Because there is a tall school building in front of it, blocking the sun's rays, the room is always so dark. When I went inside, I felt that the temperature inside was significantly cooler than outside. So, I hurriedly took out the compass, laid it flat on my chest, and started from the gate, and walked inside little by little.

This real yàn room is located in a north-facing layout, with a door in the middle, very tall, like a large warehouse. I walked slowly along the wall, and just as I was about to approach the north wall, the compass needle suddenly pointed at the black area, and it shook uncomfortably. "Oh, there's something wrong with this wall. I continued to think about walking forward, and when I walked to the place where Sun Li was sitting, the needle of the compass suddenly turned in a circle, and it shook very much. I looked closely at the snow-white wall next to the table, there was a concrete pillar here, so I took the compass and measured it near the pillar, and the pointer shook quite a lot. "Hey, this is it!"

When I got home in the evening, I told Uncle Li about everything that happened in the real yàn room.

"It seems that there must be a secret in one of the concrete pillars. Uncle Li put a filter cigarette in his mouth, and I hurriedly lit it with a match. This was bought by Tiezhu for Uncle Li, and he was advised not to smoke cigarette pouches all the time, which was not good for his health. Uncle Li is a very open person, and it is easy to accept and like the products of this new era.

"You mean that there are some Yin Spirits sealed in this pillar, so why don't we unseal him and help him reincarnate?" I asked.

"You said it simply, what year was that house built?" asked Uncle Li.

"I heard that it seems that the reform and opening up began to be built, and it was originally intended to build a large arsenal, but as soon as this one was built, it began. After the reform and opening up, the current Fangshan Middle School was built there, and because the house was large and sturdy, it was stayed. "I heard these things from the class leader Wang Jianchao, whose home has always been near the school, and he knows the situation in that area very well.

"Yes, you calculate, this house has been built for less than twenty years, and at that time who can seal a soul in a pillar? Judging from his attitude towards Sun Li, he seems to hate her very much. Uncle Li expounded his opinion.

"But Sun Li is just sixteen years old this year, and she wasn't born when she built the house, how could any yin ghost know her?" I said with some questions after listening to Uncle Li's words.

"yes, so you have to figure out the relationship between them to come up with the best way to do it. Uncle Li said: "By the way, which Sun Li do you know how much?"

Her family is Fangshan County, her father died of illness a few years ago, her mother opened a small restaurant, and she has an older sister who is two years older than her. ”

"Oh, well, I don't think there's any clue from her. Uncle Li thought about it, and suddenly smiled mysteriously and said, "Then wouldn't it be good for you to go to her house to be a son-in-law?"

"What do you say?" I was tossed by Uncle Li's face was red and green. "So what are we going to do? Which yin spirit is hurting someone?"

"Well, most likely, it seems that he is a resentful spirit, this time he is just covering his eyes with a ghost, and it is not impossible that he may let the sulfuric acid explode next time. ”

"What should I do then?" I said anxiously, "Why don't we put up a formation and seal him up!"

"That's not going to work, we can't do that until we have to, it's our job to save lives. Uncle Li said sharply: "Although this can allow him not to interfere with people's lives, he can't be born again, this is not what we do in Taipingmen." ”

"That's it, hehe, it's just a little ghost anyway, let's let him tell him why he stays here, and then find a way to solve it. ”

"Can you understand the ghost's language?" I asked, puzzled.

", if I can understand the language of ghosts, I'm a ghost, hehe, but I can let ghosts speak human language, so I can understand it," Uncle Li said with a smile.

"Let the ghost talk to people......? Could it be that you let him possess someone else, and you're telling us. ”
