Just start the riverbed. The metal pipe dug out was only the thickness of an adult's thumb, and the surface was a layer of blue-green solids, like rust. The big brother brought the machinery and equipment in the riverbed. Dig up and down twenty or thirty meters, and the metal pipe already has an adult. The thighs are thick, and there is still no sign of digging heads.

This is the end of the news, it is obvious that there is no end to it, but it has already aroused my curiosity, so I looked up at the middle-aged man in the suit, he seemed to understand, and pointed to the brown paper envelope on the table: "There are still things in it, keep looking!" ”

I opened the large envelope again and found that there were two yellowed pages of stationery inside, the top of the letterhead was printed with "Special Letterhead for the Yellow River Army", and the bottom was written "Su. Joint scientific research experts confessed to the incident", and then densely written with words, but it is quite clear.

It turned out to be a confession!

I read two lines and found that the beginning was similar to the content of the news just now, and the tone looked like a confession to the soldiers on duty that night, so in order to express it clearly, I changed the narrative:

At eleven o'clock that night, the soldier on duty heard the riverbed. There was a burst of "da-da-da" sounds, very rhythmic, as if they were being hit with metal, and they immediately ran to Su, who was living in a tent two hundred meters away. Report by the experts of the joint scientific expedition.

Speaking of which, I have to add.

When our country was first founded, and the Soviet Union. The United has the best relationship and honorifies them Sue. At that time, the country was in ruins, and it was in great need of development, and the US empire was eyeing it outside. Big Brother Lian is quite interesting, and has sent a lot of scientists and a lot of advanced equipment to our country to support.

Whether it is mining or oil mining, at the beginning, it was almost taught by people, and of course some scientific research activities were also included.

In this case, it must be the first person to look at the horse.

Several defenders came to Su. They felt strange outside the big tent where the people lived, shouting a few times, but there was no movement inside, so one of them gently lifted the curtain of the tent, and found that it was empty.

At this time, the rhythmic percussion sound of "da-da-da" has been ringing.

A few people in total, maybe Sue. Lianren couldn't sleep and went to the field to get some wind, so he decided to find out the source of the sound first, so he went to the excavation site.

That night it was a little overcast, and the pit was deep, and they found that the sound came from the pit. At that time, the lighting power of flashlights was not as good as that of modern flashlights, and in the dim light, they could dimly see a few people huddled around metal pillars at the bottom of the pit.

Their first reaction at that time: this is a thief.

In the fifties, there were still sporadic bandits in some remote areas and mountains, and although the bandits at that time did not dare to rob houses in broad daylight, they occasionally sneaked out at night to grab something or steal something, and they still dared.

Several people shone flashlights at the bottom of the pit and shouted for them to let go.

Who knew that the people at the bottom of the pit didn't move, and the sound of "da-da-da" was still ringing rhythmically, and when they listened to it again, they already felt that this sound was a little creepy, and they also vaguely realized that something was not quite right.

It stands to reason that if they shine with a flashlight, and then shout so loudly, no matter who is below, there should be a reaction.

At that time, there was no mobile phone, and there was no way to report to the superiors for a while, so several people had to bravely climb down the pit slowly.

"Da Da Da!"

"Da Da Da!"

The rhythmic beating never stopped.

The water at the bottom of the pit was up to their necks, and after a few steps of the defenders, they again pointed their flashlights at the men huddled around the metal pipes. Dumbfounded all of a sudden, they found that these people were tall and full of brown curly hair. Joint experts.

Sue. Why are the experts here, all of them are surrounded by metal pipes, and they must be holding the pipe with both hands without moving, I don't know if they are dead.

The sound of "da-da-da" came from under the metal pipe, which made them feel creepy.

The bottom of the pit is already twenty or thirty meters away from the riverbed, and there should be no people, or even living creatures, down there, so where does the sound come from?

It's scary to think about!

The first thing that comes to their mind is some legends about hell in our country, where there are nine layers of heaven and eighteen layers of hell below. A few people just felt creepy.

Sue. The joint "big brother" must not have anything to do! One of the defenders, who knew a little about medicine, hurried over and felt his pulse, but fortunately they were still alive, so he immediately rushed them to the largest hospital in the area.

Because of the international relations involved, the local authorities rushed to the hospital as soon as possible to find the best medical staff in the hospital. After examination, several people were only highly fainted, although their hearts were beating violently and their muscles were stiff, but they were free to live.

There was no good medicine in the county in the fifties, so the doctor had to choose to give a few Sue first. Joint experts are given a tranquilizer.

Who knew that the needle could not be inserted into their muscles at all, which showed the shock of the body and heart of several people before they fell unconscious, and the muscles of the whole body were in a state of tension.

Almost in a few Sue. At the same time that the joint experts were taken to the hospital, lightning and thunder were thundering outside, and heavy rain was pouring down until noon the next day. Almost at the same time as the rain stopped, a few Su. The joint expert also woke up, but he was no longer conscious, his whole body was shaking badly, and he kept muttering words that others could not understand.

When others asked them anything, they didn't respond.

The confession ended here again, my curiosity had been completely aroused, and I looked up at the middle-aged man in a suit again, and he smiled slightly: "I'll tell you the rest of the matter!" ”

Later, it was Sue. The people sent by the United Nations to take them back to China, and since then they have never set foot on Chinese soil, and later it was reported that they did not dare to come.

After such a major event, several defenders naturally couldn't get out of it, so later I had this confession in my hand.

The contents of the confession were very bizarre, and the person in charge of the military region at that time could not judge whether the confessions of several people were true or false, and when the rain stopped, they sent people to the scene, and the river was already full, and all the big pits and metal pipes were gone.

In the days that followed, they used several boats, sailors, and even some experienced fishermen to help, but they were never able to find the large pit and the mysterious metal pipe that had been dug at that time.

Time soon came to the 60s, when the local cultural department was sorting out the local old county governance, I accidentally found that there was such a narrative in the county governance of Daoguang in the Qing Dynasty in the fifth year:

At that time, the Yamen repaired the bridge, when digging the foundation on the east side of the river, dug out several strange stone statues, these stone statues each have two heads, each head has three eyes, the appearance is very peculiar, there is a bottomless hole under the stone statue, the hole comes out "woo woo woo", similar to the sound of a woman crying.

At that time, the official in charge of the project was timid, so he hurriedly asked people to bring large stones, blocked the entrance to the cave, and invited monks and Taoists to do a ritual, and then the bridge collapsed in less than three years after it was repaired. The description of the county administration is very simple, with only eight words: "There is a big pit under the bridge, and the bridge has collapsed." ”

In the late 80s, the Yellow River Army again formed an expedition team, and this time successfully found the underground cave described in the county administration and entered it smoothly.

At that time, the expedition team had sent someone back to report that there was a shocking discovery in the underground cave, but then something happened and half of the expedition team died in the cave, and then the expedition team was disbanded.
