"I heard that something happened to your department, Lin Lin."

"Our department? Let me think about it, come with me first. ”

The three of them went to Lin Lin's room, because Lin Lin's experiment was maliciously stolen before, so Lin Lin installed a hidden camera in the laboratory, and the professor also knew about it, so the three of them were watching the replay at the moment.

"Rong'er, when is the specific time?"

"I remember that it was nine twenty in the morning when Yan Yan sent me, and almost half an hour later, it was about nine fifty!"

"Okay, let's go back to nine fifty and see what happened."

At 9:50 in the morning, a boy appeared in front of the camera, he walked to the place where the equipment was stored in the laboratory, took out a scalpel, hid it, and left, less than a minute before and after.

"Isn't this boy the son of a school leader who participated in the debate? What is Li Jin's name? ”

"Such blood? Hurry up and send this video to the professor! ”

"Okay, I'll take a picture and send it to him."

After all, in the spirit of not being nosy, the three of them didn't pay attention to this matter, and Yan Yan had to go abroad in a week, for XY.

XY. is on fire in M country, there are many companies there that want to cooperate with XY., Lin Lin and Rong'er agree with Xiaoyan to talk about cooperation, so Xiaoyan is ready to talk about cooperation.

The night before, the three children found a barbecue stall and packed a large portion home, "I told you, this time to talk about cooperation, I will talk about the most powerful." ”

"Okay, good, we're all waiting to make a fortune with you, come on, Yanyan!"

"Talk about the best!"

"She's drunk again? Eh, Yan Yan, don't drink, you have to fly tomorrow, go to sleep, we'll call you tomorrow. ”

The next morning.

"Zheng Xiaoyan, get up soon, you're missing the plane!"

Zheng Xiaoyan, who was asleep, was woken up, "What? Am I missing my flight? Really? ”

"Of course it's fake, okay, get up, there's still an hour and a half."

"Xia Rong'er! I'd rather believe that I'm late than believe your again! ”

"Okay, okay, don't tease you, go wash up, have breakfast, I'll send you with Lin Lin later."

"Hmm."

"Zheng Xiaoyan, let me tell you, although we can't control you when you arrive in country M, you must video every day until you come back, otherwise we will definitely call the local 110, is it clear? Don't walk around alone, stay safe! ”

"Alright, alright, I found it, I will. Go back, I can, I'm going to check the ticket. ”

"Wait a minute, this is the necklace I made for you the other day, it's actually a GPS tracker, it can get on the plane, the signal jammer doesn't work for it, it can last for two months, it's enough for you to come back, if something happens, you call, or press it twice, and my phone will receive your help. Hopefully you won't need it, okay, go ahead, it's your turn. ”

"Okay, I remember, I'll be back as soon as possible."

"Go ahead."

The ninth day of Zheng Xiaoyan's departure.

Su and Lin opened the mobile game, and "timi" said, "Su and Lin, you are playing a game again, don't you want your graduate students?" Go learn! ”

"Big brother, I'm from the forensic department!"

"I know, what does this have to do with your graduate school entrance examination?"

"There are no people in our department who are admitted to graduate school, and besides, I am the first in my major, you don't know."

"Ah, I'm sorry I forgot, sorry to disturb, you continue hahahaha."

Zheng Xiaoyan left for the twenty-first day.

Three people on video.

"Zheng Xiaoyan, when will you come back, little rabbit cub? We're all about to get into graduate school! Xia Rong'er said.

"Eh, Yan Yan ignored her, how are you doing over there?"

"Things have changed, I can't seem to go back, and in the morning I saw people fighting metal objects. It's near the hotel where I'm staying, and it's loud and loud. ”

"So, you twist the necklace clockwise, and then put the head of the one with the necklace and the one that doesn't put it out the window, and I'll check it out of that place." Lin Lin said.

"Okay, I'll get ready."

"Okay, let's go."

After a while, Su and Lin used some technological means to turn the head into a surveillance, "Okay, I'll help you monitor it here, go and rest, good night." ”

"Xia Rong'er, come and see, I got the night mode, hurry up, I'm going to sleep."

？ Xia Rong'er stayed like this for one night.

"Morning, did you observe anything last night?"

"I noticed that someone was looking at the window of Xiaoyan's room, the kind that could look at the surveillance."

"Yes, yes, it seems that there is a serious sentry, okay, go to sleep! I'll do the rest. ”

"Okay, you take your time, I'll go to sleep."

Su and Lin uploaded the video to Zheng Xiaoyan's mobile phone and called her, "Yan Yan, don't go out for a while, I sent a surveillance video, it was Xia Rong'er who helped you stay all night last night, I let her go to sleep now, pay attention to the people in the video." ”

"Okay, I see, so what do I do now?"

"Wait and see, I'll send someone to protect you."

"Okay."

After speaking, Su and Lin hung up the phone and clicked on the video.

I saw a man in the video looking at Zheng Xiaoyan's window for a long time, although he said that there was no movement, but he was very strange.
