Looking blankly at the raindrops that quickly slid on the window glass, Chen Zhijun was startled by the sudden ringing of his mobile phone, and picked up his mobile phone to see that it was his company's vice president Lei Tongren. After answering the phone, without waiting for him to speak, Lei Tongren simply said: "There is a collapse on the mountain, come down, I am downstairs." After hanging up the phone, he sighed softly and said to himself: "There are a lot of ghost weather!" After saying that, he dropped half of the cigarette butt, resolutely slammed the door and disappeared into the rain......

"Is the landslide serious?" It was the first thing he said when he got in the car.

"Fortunately, the foreman said that the collapse injured a worker, which was not too serious and had been sent to the hospital." Lei Tongren, who had a capable face, replied.

Chen Zhijun breathed a sigh of relief and asked, "It's not too serious, why are you in such a hurry?" ”

"The collapse is not too serious, it is said that the collapse site seems to be a little abnormal, you should go and take a look."

"Anomalous? Geological problems? ”

Lei Tongren replied calmly: "Geological problems are a matter for those of us who studied geology? Now I can't say exactly what such an anomaly, anyway, the foreman gave me a mess on the phone, and he felt very weird, and he couldn't tell what it was, and he always felt that something was happening. ”

After traveling in the rain for more than an hour, the car soon reached the place of the collapse: the Gadfly Mountain Tunnel in the highway section they were building. Lao Ma, the foreman who was responsible for directing the forklift to pour gravel at the entrance of the cave, saw that the boss was coming, and immediately ran to take Chen Zhijun and Lei Tongren to the cave to take a look, and then introduced: "At the beginning, it was a little seepage, and I didn't care about it at the time, after all, water seepage is a common thing, so let them clear the gravel and hit the blast hole, ready to put another shot, who knows that when the hole is almost finished, it seems to be hollowed out at once, and a lot of water suddenly comes out of the blast hole. And it is a very small amount of medicine! I didn't think it would collapse. It is normal for a small amount of landslide to fall, but the strange thing is that this landslide is like the whole mountain being cut vertically, after the landslide, I climbed to the top to take a look, the mountain inside is pitch black, and the color of the stone is too different from the current stone. ”

The amount of the collapse is indeed not large, just like more than 50 parties, with the roar of forklifts and excavators, the gravel of the collapse was quickly cleared. Under the illumination of the light, the strange color of the mountain that the old horse said also appeared, and the blackened mountain was dark red. If you look closely, you can see that the vertical plane of the mountain is almost the same, and there is a small gap in the fixed 50 centimeters. Chen Zhijun asked the old horse to bring a hammer and smashed it on the mountain, but there was no reaction, none of the gravel broke apart, and the sound was not the familiar crisp sound when the hammer came into contact with the stone, but muffled.

"Old Chen, why is this stone so hard? What is the stone? Lei Tongren also asked after knocking on it with a hammer.

After pondering for a while, Chen Zhijun replied: "I haven't seen this stone, and they didn't find any geological anomalies when they were doing exploration. ”

The old horse grabbed the side and said, "Not a stone? What is that? Is it possible that there is no stone in the middle of the mountain, and iron can grow? No, the sound of iron should be crisp, this one is muffled. ”

After pondering for a while, Chen Zhijun wiped his hands and took out his mobile phone, and dialed his father's phone: "Professor Chen, what are you doing now?" Ask for advice! ”

"Haha, stinky boy, what are you pretending to be? I also asked for advice, let's talk about it, what's the matter? His father replied heartily on the other end of the phone.

"We found a strange thing when we were building the tunnel, after the cannon was fired, there was a black mountain, vertical, the hammer could not move, and even half of the slag was not dropped when it was smashed, and the sound of hitting it was muffled."

"Oh, what is it like?"

"This mountain is dark red and black, with a regular 50-centimeter tiny gap, the surface is smooth, but it is very hard, and the sound of the hammer is muffled, not the traditional crisp sound."

"The voice is muffled, and you still think it's a stone? You can't tell the difference between rock and wood when you study geology, right? I don't believe you've been reading for so many years. Besides, if you think it's a stone, you'll call me and ask me. ”

"Wood? Where did the wood come from in the middle of the good mountain? ”

Chen Zhijun was a little confused, but he seemed to understand something.

"You're on the scene now? Take a picture and send it to me and I'll show you. ”

After Chen Zhijun took a close-up of the panorama and a few details with his mobile phone, he immediately sent the original picture to WeChat to the past. Within a minute, his father called him back: "Stinky boy, don't move, you photographed an iron birch, the hardest wood in the world, twice as hard as steel!" If you find this in the middle of the mountain, you can be sure that your kid is lucky, the iron birch was used before the Ming Dynasty, and the quality of the iron birch at that time was even better than the current one, and the hardness was higher. I found this in the mountain for no reason, it must not have grown in the cracks of the stone, and now I can't say what it is used for, but one thing is certain, it is unusual! I've been studying archaeology for most of my life, and it's the first time I've heard of using iron birch for walls. You hurry up and protect the site, don't blindly open the mountain, send me your current location and project name, I will report to the institute immediately, and you will also report to the local museum at the same time, let them assist, don't move! The excited tone on the other end of the phone ended with a remonstrance.

Chen Zhijun pulled Lei Tongren aside, and after a brief communication of the content of the call, he decisively dialed Vice Mayor Zhao's phone.

"Hey, hello Mayor Zhao, I'm Zhijun, are you busy now? If you're not busy, I'll give you a briefing. ”

"Oh, Mr. Chen, if there is anything, hurry up, I will have a meeting in a while."

"Mayor Zhao, there was an abnormality when we hit the Gadfly Mountain Tunnel, and I suspect that we hit the ancient tomb."

Mayor Zhao on the other end of the phone asked in surprise, "What?" Tumulus! Are you sure? ”

"Yes, I just called my father to ask, my father is from the Institute of Archaeology of the Chinese Academy of Sciences, and he has studied ancient tombs all his life, he is not sure that it is an ancient tomb, but as far as I know about my father, his tone has already told me that this is an ancient tomb, and it is unprecedented."

"Secretary Wang, you go and arrange it, I won't participate," Mayor Zhao closed the door after explaining to the secretary on the other end of the phone, walked to the window and continued to ask: "What is the ancient tomb like now?" ”

"I don't know what it is, I found it by accident when I fired the cannon just now, and now it's just blown up on the outer wall of the ancient tomb or somewhere, and the specific inside is unknown."

"Got it, in this case, you stop work first, and I'll arrange it right away."

After Vice Mayor Zhao hung up the phone, he immediately contacted the director of the museum, explained the news of the suspected ancient tomb, and got up and went to the construction site of the Gadfly Mountain Tunnel.
