"What is this?"

Lu Dongye frowned slightly, staring at the thing in front of him, not knowing what it was at all.

As you can see, this thing is no more than the size of a palm, and the whole body is square, very flat, only about half a box of cigarettes.

It's like a little black box of plastic.

Lu Dongye couldn't see what it was, but Lin Fengxian said that it was amazing, I'm afraid it was really not an ordinary thing!

"Principal Lu, this is a bugging!"

Lin Fengxian's expression was solemn: "Look." ”

As he spoke, he suddenly opened the back cover, pointed to the battery compartment inside, and said, "When I found it, there were exactly two No. 7 batteries inside!"

Then, he turned the bugging device over again.

Pointing to the corner of the front, he said, "When the power is turned on, this indicator light will emit a faint green light." ”

Lu Dongye noticed it.

On the front, there is an indicator light the size of a grain of millet, and on the side, there is a microphone cut-out.

"There's a Wi-Fi card in there. ”

Lin Fengxian suddenly pulled out a small network card from the battery compartment with his fingernails: "There are four microphones, two of which are noise-canceling microphones, and the conversation in the hospitality room will be transmitted to the receiver on the other side with this wireless network card." ”

Lu Dongye couldn't help frowning: "This is obvious, it's to monitor what guests I will receive......, right? Can you be sure when it was installed?"

"It's hard. ”

Lin Fengxian smiled bitterly: "Wait for me to test it later, the power of the two No. 7 batteries, it stands to reason that the new battery should last for two months, the key is that I studied it at that time and found that this monitor is not a bargain."

If I'm guessing correctly, it must have a chip intelligent control inside, and it will only be monitored when there is sound, and the monitor will rest when there is no sound, and it will hardly consume much power, so it is actually difficult to determine when it was installed. ”

Lu Dongye couldn't help but feel a little big.

Except for Yang Hongguang, he really couldn't imagine who else would monitor him, the principal of this poor school.

"And ......"

Lin Fengxian spoke again: "There are still no fingerprints on this. ”

Lu Dongye was silent for a moment before he said: "Thank you for your hard work, Captain Lin, rest and rest, let's continue to look for it tomorrow, and secretly install a monitor, it should be considered a crime, right?"

"That's for sure!"

Lin Fengxian flipped the monitor in his hand: "Even this thing is illegal! I don't know how they got it!"

"I'll hand it over to the police tomorrow. ”

Lu Dongye couldn't help but feel a little helpless: "I just don't know, can I confirm the identity of the other party through the wireless card inside." ”

"I think it's enough. ”

Lin Fengxian was not optimistic, but he didn't say it to death: "Anyway, I don't have the ability to do this, but the current wireless cards are all real-name authentication, and it is estimated that the police must have a way." ”

"I hope I find out. ”

These were Lu Dongye's last words.

It's just that there is not much confidence in his tone.

Early the next morning.

Lin Fengxian did not go back to pack his luggage.

His exact words were: "I didn't expect that the situation at school would be more tricky than I imagined, I'll deal with it first and then go back to get my luggage, anyway, I'm not in a hurry." ”

"Then I'll leave it to you. ”

Lu Dongye only said this.

After he delivered the wild fruit to Du Liyuan.

So he sent the listener to the police station in the town.

Lu Dongye had already contacted Officer Sun in advance, after all, he was in charge of the previous Zhuang Bijun.

This matter is very likely to point to Yang Hongguang, and for Officer Sun, it is also equivalent to an unfinished case.

When it comes to returning to school.

Lin Fengxian brought another piece of news to Lu Dongye.

He looked serious and pointed to a projectile toy on the table: "Principal Lu, I'm sure that this thing was only installed last night!"

Lu Dongye couldn't help but feel a pang in his heart!

"How is this determined?"

He couldn't help but be a little curious: "Are there fingerprints on it?"

"There are still no fingerprints. ”

Lin Fengxian's face was a little unsightly: "I'm sure it's because the location of this thing was checked by me yesterday, and there was nothing in that location at that time." ”

Speaking of this, he couldn't help but sigh: "These people are really arrogant! Blame me for sleeping too heavily yesterday, and I didn't even notice that someone sneaked into the school in the middle of the night." ”

Lu Dongye shook his head.

patted his broad shoulder and comforted: "Captain Lin, it's not your fault, you were busy all day yesterday, you were already very tired, and it is normal to sleep a little deeper, and besides, the area of the school is too large, and it is also empty, how can you take care of all the places alone." ”

However, Lin Fengxian was still very unhappy, even a little sad.

As a security officer, being calculated under his nose is simply an insult to his profession!

Lu Dongye saw it in his eyes, and couldn't help but swear secretly in his heart.

After Lin Fengxian's investigation is complete, he must improve the school's security measures as soon as possible!

Just after lunch.

Officer Sun called: "Principal Lu, in the monitor, the identity of the wireless network card has been found." ”

Lu Dongye suddenly felt excited: "There must be evidence to call the police, right?"

However, Officer Sun's tone was not optimistic: "Principal Lu, after our firmness, the owner of this wireless network card is not from our province, and that person is an old man in his 70s who has never been out of the province, which shows that his identity has been stolen." ”

Lu Dongye couldn't get excited all of a sudden.

Seeing that Lu Dongye didn't speak, Officer Sun could also understand his mood, so he said: "Principal Lu, don't be discouraged, the next step, we will try to connect this listener, and then locate the receiving location in real time, and I will tell you the result when the time comes." ”

Lu Dongye could only say: "It's hard Officer Sun." ”

All afternoon.

Lu Dong and Lin Fengxian were busy all night and continued to investigate the entire campus.

By dusk, the investigation was finally over.

As a result, no hidden dangers were found.

However, Lin Fengxian still couldn't be happy: "Alas, it's better to take precautions as soon as possible, if you have to spend time checking it every day, it will really tire people to death!"

Lu Dongye nodded in agreement.

The two of them, Lu Dongye helped Lin Fengxian to help, and he barely finished the investigation.

If he checks like this every day, then he, the principal, won't do anything else.

Lin Fengxian himself has no time to do other things.

"Captain Lin, I'll wait until dinner is over, and I'll trouble you to make a list...... Let's make a simple list, and I'll go buy equipment tomorrow. ”

Lu Dongye said: "First of all, the security of the school, simply get it, and ask for the kind of equipment that can be completed in one day." ”

Lin Fengxian lowered his head and pondered for a while, and said, "Tomorrow I will go with Principal Lu, and I will take you to the place where we are professionally purchasing." ”

Lu Dongye was suddenly overjoyed.

Professional security personnel like Lin Fengxian also purchase professional security equipment.

This is a channel that he is a layman and will not be able to find at all.

At night.

Officer Sun called again.
