He hung his head, not noticing a figure coming towards him.

By the time he found out that he was not alone on this road, the other party had already passed by him.

Isn't this place abandoned? Why would anyone still be here?

He Xingchen glanced back suspiciously, but only saw a vague back, the other party was so tightly wrapped that he didn't even see whether the other party was a man or a woman.

Soon he put the matter behind him, and looked tentatively inside the gate of the orphanage, so that people who didn't know thought he was a thief.

"Officer Su?"

"Team Xu?"

He Xingchen shouted a few times in a trembling voice, but he didn't get a reaction from Su Tong and Xu Sa, but was blown out in a cold sweat by the oncoming gust of wind.

"No, it can't be that Officer Su and Team Xu have an accident again, right?" He Xingchen shuddered, but he still remembered the last time Team Xu was carried out of this place, he was covered in blood.

Thinking of this, He Xingchen's face turned white, and he quickly imagined in his mind how he would rescue people by himself if something happened to Su Tong and Xu Sa.

When Su Tong came out of a room, he saw He Xingchen standing outside the gate of the orphanage with a tangled expression.

She didn't know that in just a few minutes, He Xingchen had already made up a big scene in her mind about her and Xu Sa's injuries. stepped forward and patted He Xingchen on the shoulder, "I'll just say why haven't you arrived for so long, you are standing here in a daze!" ”

He Xingchen was excited, and when he saw that the person who came was Su Tong, he was so moved that he almost cried on the spot, "Officer Su, are you okay!" ”

Frightened by He Xingchen's excited reaction, Su Tong looked at him funny, "What can I do?" Come on in, we've got something for you to look it up. ”

"He Xingchen?" Xu Sa also heard movement inside, and stretched out his head, "What are you doing standing there, don't you know that time is pressing?" ”

As soon as he saw Xu Sa, He Xingchen calmed down, quickly wiped the cold sweat on his forehead, and walked in tremblingly, "Team Xu ......"

Xu Sa had an unlit cigarette in his mouth, and glanced at He Xingchen with slanted eyes, his face was a little ugly, "Hmm." Do you have a computer? ”

"Bring, bringing!" He Xingchen hurriedly took off his backpack, took out the black notebook inside, and explained, "The computer, I always carry it with me." ”

Indeed, he forgot to bring his documents to work, and he would never forget to bring his computer.

Xu Sa nodded, and pointed with his big hand, "Those things over there, can you find out where the signal is going?" ”

He and Su Tong found pinhole cameras in various rooms of the orphanage, there were twelve so far, and there were still some rooms they hadn't finished.

He Xingchen looked at Xu Sa's hand, and when he saw the things piled up on it clearly, he was obviously stunned, "This is, pinhole camera?" ”

"Well, when Xu Sa and I found these things, we didn't find the existence of signal transmitters or anything like that, so I asked you to come over and have a look." Su Tong nodded solemnly.

Pinhole cameras typically transmit images wirelessly, so a small transmitter is usually found on the camera.

But the cameras she and Xu Sa found were really just a camera, and even they couldn't be sure that these cameras seemed to be still running.

He Xingchen didn't care if the ground was clean or not, threw his backpack on the ground, sat cross-legged, and began to fiddle with those gadgets.

"Judging from the models, these cameras are the latest models this year......" He Xingchen only looked at two and came to a conclusion.

"The advantage of this camera is the long standby time and the fact that it does not need to be paired with a transmitter. Because they are equipped with a signal point inside, when the buyer buys, the seller will connect this signal with the buyer's electronic products. ”

"This way, buyers can see the camera footage on their electronic devices at all times."

"However, there is a downside to this thing. Because it is not equipped with a traditional signal transmitter, the range of images that can be transmitted by the camera is very short, in other words, the person who uses this camera cannot see the image captured by the camera anytime and anywhere. ”

Xu Sa's expression froze, "Then are these cameras still running now?" ”

If it's still running, there's a good chance that their conversation will be heard by the person who installed the camera.

"Well, I'll have to take one apart first." When it comes to electronic devices, He Xingchen speaks a lot more fluently, "Team Xu, can I take these things apart?" ”

"Demolition." Xu Sa waved his hand, "It's best to find out with me who the people connected to these cameras are!" ”

With so many cameras installed in the orphanage, it must be someone related to the orphanage, and it is even more likely that they are looking for a murderer.

"Xu Sa......" Su Tong frowned slightly, "Did you hear what Xiao He said just now?" If the person who installed the camera wants to see the images captured in the camera, he has a data limit......"

"That is, that person must be around the orphanage."

Xu Sa didn't interrupt her, and motioned her to continue with his eyes.

"You should know better than I do what this area is like, especially this orphanage, according to the addict, no one comes all year round......"

"You say, let's check the surveillance footage in the neighborhood and find out the people who frequently appear in this area, will we find the person who installed the camera?"

Xu Sayou raised his eyebrows thoughtfully, "The solution is a good way, but as you said, the environment in this area is complicated, and those who have appeared around for a long time should be familiar faces in this area." Even if we call up the surveillance, there must be a lot of people who will find it in the end. ”

"So, what we're looking for now is not the person who installed the camera, but the root cause. Figure out the purpose of installing these cameras in the orphanage, and then trace down the person who installed them. ”

After saying that, both of them were silent.

He Xingchen was completely immersed in the self-entertainment of dismantling the camera, and did not notice the change in the atmosphere between the two.

"It seems that this time the two of us have different opinions." Su Tong raised his eyebrows, "In that case, why don't we take a gamble?" ”

"Bet?" Xu Sa's eyes flashed with interest, "What are you going to bet on, if I don't dare to be interested......"

"You have the final say, let's bet on who can find the person who installed the camera first." Su Tong interrupted him.
