Mysterious footsteps

At midnight, the silent museum suddenly heard the sound of footsteps. ...

Museum fear

"Dudu, pack your things quickly, we have work to do again!" One day during the winter vacation, everyone was watching The Adventures of Sherlock Holmes intently in the room when his private detective father came in.

"Dad, what case is this?" Dudu suddenly got excited.

"It's a case about a haunted house: a museum often has mysterious footsteps in the middle of the night, which scares the people in the museum. In this way, the staff are afraid to work inside. " Dad said, "This case is very special. Let's go. "

Dudu followed his father and soon came to the "crime scene". This is an ancient temple in the mountains, and the museum is located in the ancient temple. The buildings in the ancient temple are all wooden structures, and several buildings such as main halls, meditation rooms and zhaitang have formed a large-scale and orderly arrangement of buildings. This ancient temple has a long history, which is said to be 1000 years old, but it is well preserved as a whole.

"Strange footsteps have only recently appeared," said Liu, director of the museum. "Our museum has not been built for a long time, and its purpose is to protect the cultural relics in the ancient temple. After the museum was built, we arranged for the staff to keep vigil every night. I didn't expect it to be less than a month, and everyone heard inexplicable footsteps. "

"Can you arrange for me to meet the person on duty?" Dad listened to the introduction, thought about it and asked Lao Liu.

"No problem, I'll call them over." Lao Liu readily agreed.

After a while, Lao Liu brought a middle-aged man and a young man. "This is the detective I invited, and these two are our staff, Lao Guo and Xiaocao." After the introduction, Lao Liu said to them, "Tell the detective what happened at that time."

"I was on duty that day when I suddenly heard a strange' scraping' sound in the hall. It sounds a bit scary in the middle of the night, but I was afraid that some criminals would steal cultural relics, so I got up the courage to go to the hall and have a look. But strangely, there is not even a shadow in the hall. " The grass swallowed, and some went on trembling: "I thought I heard it wrong, but in the next few days, this voice appeared several times, and it sounded ... like human footsteps."

Dudu heard what he said so scary that he couldn't help shuddering.

"Well, not long after, when I was working overtime, I also heard this strange voice." Lao Guo went on to say, "I was developing photos in the darkroom of Toudian, which is located in the front section of the ancient temple. Suddenly, I clearly heard a man's footsteps coming down the steps. When I rushed out of the door to see it, it was empty outside and there was no one there. "

Rumors and clues

"Uncle Liu, have you ever heard this kind of voice with your own eyes?" Dudu couldn't help interrupting.

"Yes, it sounds like people walking around in cotton shoes. It has a strong sense of rhythm and it sounds a bit creepy." Lao Liu said: "Since the sound appeared, everyone was a little scared, and no one dared to be on duty at night."

"What do the surrounding residents think?" Dad asked.

"Many people say it's a zombie." Lao Liu looks a little pale. "Because some cultural relics were exhibited in the ancient temple recently, including a man's body excavated from the ancient tomb of the Yuan Dynasty, the residents all pointed their finger at the museum and our exhibition was forced to stop."

Is God asleep? Dudu and his father looked at each other quickly. They followed Liu to the exhibition hall where the remains of Yuan people were parked.

The crumpled body was sealed in a glass cover and looked like a charred charcoal from a distance.

"God's sleep is just a superstition," Dad said, touching the glass cover. "Besides, the glass cover is so strong that even if the zombies can be resurrected, they can't get out."

"We also know that zombies can't be resurrected, but what's wrong with that voice? If we don't find out the reason, the fear in everyone's heart will only increase day by day. " Lao Liu said morosely.

"Could it be a mouse?" Dudu put forward a hypothesis.

"It can't be a mouse." Lao Liu flatly denied that "the mouse can't make such a loud noise, and the sound of mouse activity doesn't match the sound that everyone hears."

"What about other animals, such as wild dogs and wild boars?" Dudu went on to assume.

"We also speculated about this, but there are many villagers living around the ancient temple, and the walls of the temple are not damaged. It is impossible for large animals to enter the yard." Lao Liu said.

What the hell is going on? Dad looked at it carefully in the hall. He stopped from time to time and took out a magnifying glass to examine it carefully.

"Dad, any clues?" Dudu squatted beside him with a confused face.

"There are some eyebrows at present." Dad smiled and said, "However, whether my guess is correct depends on the actual situation tonight."

"Dad, what's going on? Let me talk about it first. " Dudu is anxious to know the result.

"The investigation here has come to an end temporarily. Let's go to the Meteorological Bureau to find out about the situation and come here at night. " Dad didn't answer DuDu's question and went straight out of the ancient temple.

"Go to the Meteorological Bureau to find out about the situation?" DuDu Zhang and two monks are at sea.

Mysterious "culprit"

In the county meteorological bureau, dad didn't mention the strange noise in the museum, but learned about the local weather and climate characteristics from the staff in detail.

Night soon fell, and Dudu and Liu waited together in a small room next to the main hall of the ancient temple, waiting for the mysterious footsteps.

"Chen Wenjing, Chen Wenjing ..." Suddenly, footsteps similar to people walking came from the silent hall, which was creepy.

"Quick, go out and have a look!" Dad rushed out first, but the hall was empty.

"Is it really weird?" Liu broke out in a cold sweat on his forehead. And doodle was a little scared.

Dad didn't speak. He walked quickly to a corner and examined something carefully.

Under the flashlight, Dudu and Liu saw that it was a broken filament.

"I should be able to find the reason!" Dad has a proud expression on his face.

"This silk is how to return a responsibility? Did you find the reason? " Lao Liu and Du Du are both confused.

"This broken silk thread shows that two pieces of wood in this corner have just shifted, and under their pull, this thin thread is broken."

"You mean: The sound of' Chen Wenjing' is made when the wood shifts?" Dudu's heart was suddenly enlightened.

"Exactly!" Dad said happily, "I suspected that the sound was coming from these Woods from the beginning." Because wood usually deforms, cracks and bends when the temperature and humidity change greatly, if the deformation range between two buildings is different, dislocation will occur. After dislocation, the wood is squeezed and expanded, and after accumulating enough strength, it will break or shift, accompanied by some noise. "

"Ah, how did you come up with this phenomenon?" Lao Liu feels a little incredible.

"In the afternoon, I took Dudu to the Meteorological Bureau to learn about the weather and climate characteristics here," my father said. "I realized that the area where the ancient temple is located is very humid in summer, but it becomes very dry in autumn. After autumn, the wooden buildings of the ancient temple will shrink because of the cold and dry weather. In order to verify the displacement of the wood, I quietly fixed the silk thread at the joint of the board wall in the hall. As long as the wood moves, the silk thread will break. "

"What a famous detective!" Old Liu Can couldn't help admiring.

"In fact, we will encounter such a situation in our lives. For example, in winter, due to the large temperature difference between inside and outside the house and the dry air, the wooden floor or furniture at home sometimes suddenly gives out a bang. If you were watching a horror movie, you would probably be surprised by the sound. There are also roads, bridges and railways. And there should be a gap at the junction of each section, so that when the season changes and the temperature and humidity change, the phenomenon of thermal expansion and cold contraction will not cause the displacement and deformation of the road surface. " Dad continued to preach.

Chen Wenjing and Chen Wenjing ... The noise in the hall continues, but Liu and Dudu are no longer mysterious and afraid.
