The snow wolf team and the people from the action team came to Chen Tianhao's house, and Lin Song, Zhao Xuelin, and Zhao Dongfeng walked into the door where the original original stone was stored at the same time.

Chen Tianhao also walked in after them, and said with a worried expression: "The original stone disappeared from this room. But we've installed surveillance in the room, and the door to the room is basically locked, and I don't know how that could happen. ”

Lin Song looked at the environment of the room: "Zhao Dongfeng, have you checked the scene before?" ”

The thing was thrown away under Zhao Dongfeng's nose, although Zhao Dongfeng had the heart to argue, he still lacked confidence, so he could only say; "Checked, there are no signs of broken door locks at the scene. But this door lock is a mechanical lock and an electronic combination lock double insurance.

Therefore, it can basically be ruled out that someone has opened the door lock through normal channels. ”

"In other words, the person who stole the rough stone could never have walked in through the gate." Lin Song said and began to search slowly in the room.

Strictly speaking, the room is actually a secret room, and there is not even a window outside of such a door, and if you usually encounter this situation, most of the problems are found from the ventilation vents in the ceiling. However, after Lin Song's inspection, he found that the tuyere here had also been treated with anti-theft.

A huge tuyere, sealed with an iron grate the thickness of a thumb, let alone an adult, not even a bird can fly in, and it is all covered with dust, and it does not look like it has been moved at all, so it can basically rule out the possibility that the thief came in from the ceiling.

"By the way, how is the surveillance in the room displayed? Don't you have surveillance? Qian Donglu asked.

Chen Tianhao sighed: "It's strange to say this, the surveillance screen was originally normal, but suddenly it began to be disturbed, and finally it directly became a snowflake spot." I can't see anything.

As soon as the rough stone was stolen, we had already checked the surveillance footage, but in the end we found nothing. ”

In the end, Lin Song's eyes fell on the floor, and he walked back and forth on the floor, but he really didn't find any problems. Suddenly, Lin Song's eyes flickered: "Look for ultraviolet lights!" ”

The people next to him were stunned: "Ultraviolet lamp? Let's go find it. ”

Soon, someone returned to the scene with an ultraviolet lamp, and Lin Song asked people to turn off the lighting equipment directly, and it suddenly became pitch black, however, when Lin Song lit the ultraviolet lamp, he suddenly found that there was a floor tile in front of him, and a bright area appeared on the four sides of the rectangular shape of this floor tile.

Lin Song hurriedly rushed over and knocked twice on it with one hand, but the sound was dull, there was no hollow sound, and the floor tiles were also very solid, not like they had just been moved.

"What are you doing in a daze, find a tool! This is where they are clever, using special glue to seal this place, and there is no way to determine whether the ground is empty or not by ordinary means. Lin Song said.

The lights turned on again, and the two soldiers found two large hoes from the flower garden, and under Lin Song's order, they directly dug up the floor tiles, and at this time, everyone found that under the floor tiles, someone had put something similar to a cement block.

"It's a special material that dries and sets the shape and is used to pad under the floor tiles. Dig even further! Lin Song ordered.

The two warriors continued to dig downward, and in a minute or so, a deep pit appeared, and all around this shaft-shaped pit were very uniform and neat, and there were traces of chisel drilling.

Lin Song frowned: "This thing seems to be very interesting, bring the equipment, I'll go down and take a look!" ”

Several soldiers next to him hurriedly sent their equipment, and after Lin Song was dressed neatly, he tapped the camera on the tactical helmet with his hand: "I am in the picture below, you can see it at any time." My only command is that no matter what you see for a while, as long as I don't order you to come down, you must not come down rashly! ”

"Yes!" Everyone hurriedly said.

Lin Song took the equipment and began to climb down little by little, both sides of the shaft were now silt, which looked very slippery, but Lin Song was a child from the mountain after all, and he was relatively comfortable coping with the situation in front of him.

After about a minute, Lin Song came to the bottom of this shaft, but what made people a little frustrated was that the point of this shaft was actually a dead end, and when the shaft reached here, there was no follow-up!

Lin Song's first reaction when he found out about this situation was whether he was a ghost hitting the wall, how could it be! How could the other party have come in from here! How did the other party get out!

He stretched out his hand and groped around, and soon, Lin Song noticed that the soil here seemed to be a little looser than in other places. Lin Song hurriedly said: "Let's go, recently, the weather conditions in the border cities, as well as the information that has become the composition of the local soil, have been sent. ”

The comrades-in-arms above heard Lin Song's order and hurriedly did so, and soon, these materials were first on the wearing lenses of Lin Song's tactical helmet, and after Lin Song read it carefully, he first frowned, and then said directly: "Go, help me check the sewer network map of this nearby area." ”

"This network map is classified information, and we need time! You'll have to wait a minute. Zhao Xuelin said.

"Can't wait! You don't have to look for it, just call back to the brigade and let the brigade leader find it! It's faster this way! ”

Zhao Xuelin sighed, and hurriedly went to contact the team leader, sure enough, Zhang Xiong came forward directly, and he got the pipe network diagram relatively quickly, and similarly, Zhao Xuelin sent the scanned pipe network diagram to Lin Song.

Just a few minutes later, Lin Song looked at the pipe network diagram, and his heart suddenly brightened: "I know, the other party came in from the sewer!" Attention everyone, notify the local police ......"

Speaking of this, Lin Song paused, what could he do by informing the police? Blocking the sewers? Now in this situation, how to block? With the equipment of the police, if you take the initiative to enter the sewers to search, I am afraid that it will be even more troublesome.

In that case......

Lin Song gritted his teeth and made a decision directly: "Notify the police personnel outside, let them mobilize all the vehicles that can still move, and use the wheels to press the manhole covers in a few nearby blocks, they must be fast, otherwise the other party will leave immediately!" ”
