lu yinxi was on guard.

she didn't think it was an illusion. she was indeed followed.

the hair on lu yinxi's back stood on end when she didn't notice the person following her. she unconsciously quickened her pace. as she walked, she used the old phone left behind by the police to call for help.

before the call went through, lu yinxi had already walked to the elevator. just as lu yinxi was about to press the elevator button, a man's voice suddenly rang out behind her. " student lu. "

lu yinxi turned around.

!!

she saw a young man in a police uniform.

"and you are?" lu yinxi had never seen this male police officer before.

the police officer took out his id and showed it to lu yinxi. lu yinxi noticed that he was wearing a pair of black leather gloves. when he saw that lu yinxi was looking at his gloves, the male police officer smiled. his smile looked quite cute. he said, " it's quite cold at night. when you go to the police station, wear your gloves to keep warm. otherwise, your hands will be numb when you drive. "

"yes, i am."

lu yinxi didn't think much of it. she took his police id and looked at it.

the man was called chen tong, 26 years old. he was a police officer in the investigation department of a branch of the binjiang municipal public security bureau. lu yinxi had seen the work ids of the other police officers before. after confirming that this one was not fake, she relaxed.

with the police here, he should be out of danger.

lu yinxi's finger had been on the dial key for a long time, and she finally moved it away.

"why are you looking for me?" lu yinxi asked the male police officer named chen tong. lu yinxi felt a little strange and said, " the police who came to look for me before were all from the major crimes division of our city headquarters. why are you looking for me? "

this case should not belong to their branch.

"student lu, you're quite cautious." officer chen smiled. seeing that the elevator had arrived, he said, " let's talk in the elevator. "

lu yinxi was very cautious at this critical moment. lu yinxi wouldn't take the elevator alone with a stranger before she figured out why he was there. at that time, he would not even know how he died.

lu yinxi stood at the door and didn't go in. instead, she looked up and asked officer chen, " what are you looking for me for? if you have anything to say, say it here."

chen tong seemed to be somewhat stunned.

"are you suspecting me?" chen tong didn't know whether to laugh or cry.

lu yinxi's expression was serious. " i suspect any unfamiliar face, " she said.

seeing this, chen tong was stunned.

he put away his smile and said to lu yinxi, " it's like this. the higher-ups said that it's not safe around you recently, so they sent us to protect you. " my job is to go to your house and install surveillance cameras and bugs. if anything happens to you, we'll be the first to hear it. "

hearing this, lu yinxi was 70 – 80% convinced. however, she still had her doubts and said, " you've already left me a phone. i can call you if i'm in danger. "

" it's not enough to just use the phone. we have to make sure everything is foolproof. "

as they spoke, the two of them walked towards the elevator.

after entering the elevator, the police officer with the surname chen pointed to the bag on his back and said, " there are surveillance cameras and bugs in here. i'll place them in your living room. if anything happens, you can call for help. "

"oh, okay."

lu yinxi and chen tong walked out of the elevator together, with chen tong slightly ahead of lu yinxi. lu yinxi opened the door and invited chen tong into the house. when they entered the house, lu yinxi said to chen tong, a little embarrassed, " i don't have men's slippers at home. you can come in directly. you don't have to take off your shoes. "

"alright," he said.

chen tong carried his bag and entered the house.

lu yinxi asked him what he wanted to drink, but he refused to drink anything. lu yinxi felt that this was not good, so she said, " i'll pour you a cup of hot water. it will probably take a while for this to be installed. drink some hot water to warm your stomach. "

"that's going to be troublesome."

chen tong put his bag on the coffee table. he opened it and took out various surveillance devices.

lu yinxi glanced at him. seeing that he was really here to install a listening device, she was relieved. she went into the kitchen, washed a cup, and poured a cup of hot water. lu yinxi brought a cup of hot water to the living room and handed it to chen tong.

"put it on the table, i'll drink it later." chen tong was fiddling with the equipment in his hand and didn't have time to drink water.

with a guest present, lu yinxi naturally couldn't leave him behind and go back to her room to do her homework. it would be impolite.

seeing that lu yinxi was sitting on the sofa, chen tong said, " student lu, go do your own things. don't worry about me. "

..."that's good."

she went back to her room to do her homework. it wasn't good to leave chen tong here alone. lu yinxi thought about it, then picked up her bag and went to the dining room. lu yinxi put her book on the table, took out a pen and paper, and started to do math questions.

the room was very quiet. only chen tong's movements could be heard in the living room. lu yinxi would occasionally turn back to look at him. seeing that he had been working with his head lowered, she also calmed down and did her homework.

after an unknown amount of time, lu yinxi wrote down all the calculation steps on the manuscript paper and calculated the answer to a difficult problem. she felt that her neck was a little sore. she put down the pen, looked up, and rubbed her neck.

only then did she realize that something was wrong.

why was the room so quiet?

lu yinxi turned around in surprise. she saw that the police officer named chen tong had come to her side.

"what's wrong? do you need anything?" lu yinxi thought that chen tong wanted to borrow some tools.

chen tong smiled and said, " i have something to borrow from you. "

"what? banshou is still ..."

"student lu's life,"

lu yinxi's eyes widened.

she widened her eyes and stared at the cute-looking male police officer in front of her. she felt a chill down her spine. "y-you're the murderer?" she subconsciously reached out to grab her school bag, intending to use it for self-defense.

chen tong's face still had that faint smile.

before, lu yinxi had thought that his smile was cute, but now that she saw it again, she felt that it was creepy.

chen tong didn't explain. he took out the hand that was behind his back.

lu yinxi saw that he was holding a 20-centimeter-long sharpening stick in his hand. this kind of sharpening stick was very common in the pork stalls in the vegetable market. the butchers would always put a sharpening stick on the stall. when the knife was blunt, they would sharpen it on the sharpening stick and cut the meat very quickly.

"that's not right." in her panic, lu yinxi suddenly realized that something was wrong. " you're not the murderer! " she said. lu yinxi looked at chen tong's young face and said, " more than ten years ago, you were only in your teens. how could you kill someone ... " chen tong approached her.

he grabbed lu yinxi's throat with his gloved left hand.

lu yinxi raised her bag to resist.

chen tong kicked her bag away.

lu yinxi lost her only self-defense tool. her face instantly turned pale, and her legs went weak from fear. chen tong patted lu yinxi's cheek with the sharpening stick and said, " who told you that the murderer is the same person who has been killing people for more than ten years? "
