Half an hour later, a convoy of more than a dozen police cars roared to the foot of the mountain, which was the first police force from the county to come to support. After their arrival, dozens of police officers quickly surrounded the mountains around the cave. The mountainous area, which was dark more than half an hour ago, is now full of activity.

After another half an hour, more police officers arrived from the city. The excitement I just said was just the light of the flashlight and the slight sound of words, but now the human voice and the barking of the police dog are all blended together, and it is very lively.

While Professor Chen was standing by the tent and thinking about what it would be underwater, Sun Bureau of the Public Security Bureau appeared next to him out of nowhere. Seeing what Professor Chen was thinking, Sun Ju gently interrupted, "Professor Chen, what are you thinking?" ”

As soon as he saw Sun Ju coming, Professor Chen quickly stretched out his hand and shook it and said, "Sun Ju, it's here." ”

"I must have been there for something so big; Now all the roads leading to here have been blocked, and several mountains on the side have been blocked, and we will officially search the mountains as soon as dawn, and now we will search a small area first. ”

"Sun Ju, I watched the video just now, and I think that person is quite proficient in playing explosives, and he controls the amount of explosives very well, and he is very professional, has there ever been such a case in the past? Or are there people who have a criminal record and are very experienced with explosives? ”

"If you play with explosives, we haven't found them in all the past cases, at most they are illegally mined stone factories, they are all bought on the black market and blown up indiscriminately, like you said, professional play, has not been found yet. Team Wu told me about the situation here just now, he should be coming for something underwater, so what is down there, can you roughly judge it? ”

"Now it's not clear what exactly is below, but what can be roughly confirmed is that it should be a bronze casting, and what its use and value are not very clear at present."

"Oh, that means where did that criminal get the information about that artifact now, and it must be of great value and significance, otherwise he wouldn't have stolen that thing under such a police guard, or even robbed it openly."

"Yes, I'm also thinking about this question, if it's a cultural relic, there are more things in the Han Dynasty, and there are more things he can steal, that person is very professional, so that he doesn't know that there are gold and silver treasures in the stone pillars in the south, and that is still this scaffolding, it is very conspicuous, it has just rained, how good it is for him to find someone to cooperate with quietly stealing those, why do he take so much risk to steal things underwater, so I judge that there must be other information on that thing."

"Oh, what could it be?"

"I can't say it right now, it's just a feeling, it should be some kind of positional suggestion and so on."

"Oh, let's do it first, Team Wu said that the criminals may still be in this cave, so a vibration alarm is now installed inside, as long as there is any movement, the alarm will be triggered, and the police force at the entrance of the cave will not move, so as to ensure your safety, you also hope to take them wherever you go, so as not to have an accident."

"We're fine, we're just worried that we won't be able to get it back."

"Don't worry, as long as he doesn't walk out within half an hour, he won't let him slip away! I've arranged for the police dog to follow the footprints left in the cave to find out how he got here, and then to see if there is any other information left for us. ”

"Okay, then you work hard, and we will continue our work after dawn to ensure the safety of those gold and silver treasures."

"No problem! Starting tomorrow, I'll give you SWAT officers within three meters of your work. ”

Professor Chen just wanted to say something more, but Sun Ju's mobile phone rang, and Sun Ju connected to the mobile phone and listened to the meeting and said, "Are you sure he came alone?" You guys extend another 500 meters, 1000 meters to search, see if you can find a double car print or something, um, well, if you find it, report it immediately. ”

After hanging up the phone, Sun Ju said to Professor Chen: "Professor Chen, now that the vehicle that the criminal is riding in has been discovered, now we will first investigate the vehicle information, and then visit and investigate the owner of the vehicle; However, my personal intuition is that the car was stolen, so I first know where the criminal came from through this information, and check through the cameras along the road to see if I can find out the true face of this person. ”

After saying that, Team Wu and Ju Sun went to the cave to see the scene, Zhang Gong saw the two of them leaving, so he walked up to Professor Chen and said: "Old Chen, it seems that our information is lagging behind, it should be that the stolen thing has important value, otherwise that kid would not have taken such a big risk to steal this." ”

"Yes, I'm thinking about this too, I think it's more likely that this person was hired, and he himself may not be too familiar with this."

"A person accomplishes such a thing, it means that this person is afraid that we will take out the lost things first, he wants to steal this in front of us, or even say that it is snatched, if the value is small, it is not worth it, after all, this risk is too great, but the heavy rain in the afternoon helped them a lot, so they took the opportunity to steal this thing, they will not be unaware of this risk, although the wind and rain helped them destroy the equipment outside the cave, but their risk is not really reduced."

"Well, Lao Chen, let's report this matter."

"You decide after dawn."

"Lao Chen, I'm worried now, we don't know which direction the underground river flows from, and now the water in the cave has been dripping down through infiltration, but after so many years, the water level seems to have always been like this, indicating that the water here will flow out through which hole in the ground when it is full, I'm afraid that the thief will run away from there."

"Well, ignore this, quickly use ground penetrating radar to detect this mountain, you will definitely find clues!"

After speaking, Professor Chen pulled Zhang Gong and two policemen with guns and began to probe along the mouth of the cave.

After more than three hours of exploration, I finally found it in the back of the cave, that is, by the stream between the two mountains: after the water in the cave overflowed to a certain position, it was connected to it through an underground river with a diameter of about 1.5 meters, and then flowed into the lake through a small stream.

Professor Chen looked at the exit and said, "If that person has already come out of it, then he must only come out here, and find a police dog here to try it, maybe he will find it." ”

The two police officers who came with him felt that this was a direction, so they hurriedly reported the discovery through the walkie-talkie. Soon, more than a dozen police officers came with two police dogs, and after the police dogs sniffed at the exit of the water flow and found nothing, they separated into two roads, all the way up the stream, all the way down to continue the search.

Just as Professor Chen was about to return to his tent, there was a slight noise and vibration from the mountain, and then the water at the outlet of the underground river suddenly became significantly stronger.

Seeing this movement, Professor Chen hurriedly pulled the policeman on the side and said softly: "It's exploded inside, there is a situation here!" ”
