Anping heard the head of the household say that there would be a rolling marble sound on the floor late at night, and he was shocked.

Fortunately, the head of the household didn't notice his expression, and was still babbling: "Master An, for the first few days after this voice came out, we didn't care, and thought, isn't this plumber single, how could he bring a child to live here, alas, living together is none of our business, but he shouldn't let that child play marbles every night affect our family's rest." ”

The head of the household sighed, his face began to have some horror, and continued: "A few days later, I couldn't bear it anymore, so I went to negotiate with the plumber, but I didn't find anyone for several days, and then I finally met him. ”

"We all thought it was very strange, and we went to the attic together, and found that everything was normal in the attic, except for a bed in which the plumber lived, and simple pots and pans, and some of his tools, not even a chair and a table."

"At that time, I froze, wondering if there was something wrong with our family's ears, and later, when the plumber was not at home, our family held our breath and listened carefully, and the voice came out again."

"Now we all panicked, thinking that there was something unclean upstairs, we burned the paper several times, but we didn't see the effect, the sound of marbles was still ringing, so we thought, please Master An come and help us do it, and drive away the dirty thing."

An Ping muttered: "My master once said that if in the dead of night, you will hear the sound of marbles coming from the floor from time to time, then this family will either have a bloody disaster or will be haunted by bad luck, because the younger the soul of the unjust soul who died, the heavier the grievance, and the sound of marbles can be heard, it is the soul of the deceased child, which is called the infant spirit, which is even more terrifying." ”

After hearing this, the head of the household suddenly turned white with fright, and begged An Ping to help him exorcise the evil spirits, and he would be rewarded heavily.

When Anping heard this, his face showed embarrassment, and when the head of the household saw this, he understood it and immediately increased his salary and proposed a more generous reward.

In fact, Anping's appearance is not to cheat more money, but he just heard about this kind of thing, but he has never really encountered it, and he is really not sure, I don't know if he can help the head of the household solve this difficulty.

But seeing the generous conditions offered by the head of the household, Anping couldn't stand this temptation, and agreed, saying that he would come to exorcise evil spirits three days later.

An Ping, who had received the deposit, wandered around the street with a sad face, thinking about how to do this.

He thought of inviting other peers, but he was really unwilling, if he did this, it would be tantamount to smashing his own signboard, and there would never be any business to patronize him in the future.

In his helplessness, he unexpectedly saw the figure of his master Zhang Yuanshan, An Ping's heart moved, and he was overjoyed, so he stepped forward to greet Zhang Yuanshan,

Hearing Zhang Yuanshan finish speaking, Li Bing laughed and said, "Brother Zhang, I dare to pack tickets, you have a hot hand for this money." ”

Zhang Yuanshan was stunned: "Li Bing, how can you say this." ”

Li Bing said: "Brother Zhang, I have also heard of the sound of marbles you said, folk superstitions are true, if it is really a baby spirit, I believe that with your brother Zhang's ability, you can naturally disperse him, but this marble sound is not a baby spirit trouble at all, so no matter what you do, the sound will not disappear." ”

Zhang Yuanshan said strangely: "Li Bing, tell me your opinion, what is going on." ”

Li Bing smiled: "In the dead of night, there is a sound on the floor similar to the sound of marbles falling to the ground, and most people will think that this should be the children upstairs playing when they hear it for the first time, so they won't take this matter too seriously, but if there is no one living upstairs in your house, then how will you think about it in your heart." ”

"There is a superstitious saying among the people, saying that don't think that there are children playing marbles in the middle of the night, that is the call of death: there is something unclean that gouges out their eyeballs and falls to the ground to play, and the person who can hear this sound is actually hearing the sound of the black and white impermanence of the urging gong."

"More superstitious people vividly say that the sound of marbles is said to be heard only by children, or by some people with low yang energy, anyway, after hearing this sound, it is very unlucky, either a dead person, or everything is not going well."

Several other people shouted out in surprise, and Li Bingle said hehehe: "Why are you doing this, it's not true, I mean folk superstition." ”

Zhao Wan'er said: "Li Bing, who made you say it so mysteriously, it really scared you to death, when I was at home, I would sometimes hear this kind of voice occasionally, but I didn't know that there was such a statement, so I didn't feel scared, now that you said it, do you say that I can not be afraid, quickly talk about your other opinions, don't let me be too entangled in my heart." ”

Li Bing grinned and said: "Obey, in fact, the appearance of this marble sound is based on science, not like folk superstition and legends." ”

"The culprit of this marble sound is not actually a ghost, but an incomplete mold of the class of molds, which corrode industrial materials and cement, and most of them like to gather on porous surfaces and feed on the minerals in cement."

"Generally, the ceiling in the building room is supported by the upper and lower layers of fine steel bars when casting, and during the grouting process, due to various reasons, the steel bars are not straight and are stuck in the cement, and the flow and weight of the cement slurry may have upward or left and right stress accumulation."

"After the house is built for several years, there may be earthquakes or small displacements of the foundation or other people's home decoration smashing the wall caused by vibration, etc., the fine steel bars in the cement floor will produce new stresses, there are pipeline outlets of electric light lines in the lower layer of the ceiling, as well as temperature and air temperature, etc., which will cause mold to gradually invade the gaps in the cement floor along the hole."

"The contact surface between the fine steel bar and the cement in the floor slab is the ideal gap, where the mold is multiplurished, and the mycelium begins to erode into a hollow pipe around it, and when the cement around a stressed steel bar is eroded to a certain extent, it will bounce back and forth in the hollow pipe, which is the source of the marble sound."

"It turns out that the sound of thin steel bars bouncing in pipes is the most similar to the sound of marbles, and this happens mostly in uninhabited rooms where you can hear this strange sound of marbles underneath."

Li Bing said with a smile: "You all understand now, if the floor is thick, the probability of this marble sound is very small, the family that Anping went to is a demolition and resettlement household, generally such a building, will cut corners, the floor is very thin, so it is not strange to hear this sound." ”

"Brother Zhang doesn't actually need to do it, the easiest way is to place some large and bulky furniture on the floor, and this sound will naturally disappear."
