"Wang Yi, Nuo, this is the morning I bought for you." Zhou Yu put a bag of bean paste bags and a cup of freshly ground soy milk in front of Wang Yi in his hand and said softly. Every time she faces Wang Yi, Zhou Yu always has a special feeling, which always makes her can't help but want to understand this person, when she first joined the police station a year ago, she was 178 tall, medium in stature, and handsome. The man who always wore a pair of black-rimmed glasses on his face was deeply attracted. His expression was always calm at all times, as if nothing was worth his ups and downs.

"What kind of picture is this? Are these your friends? Or classmates? Seeing that Wang Yi didn't react, he was silent and in a daze with an old photo in his hand. Zhou Yu was a little annoyed, in the morning that people worked so hard to buy for you, you have to say thank you.

"These are my classmates." Wang Yi's voice was a little hoarse, and it could be seen that he was not in a very good mood.

"I haven't seen you in years, right? Are they also in Changling City now? Why don't you get together? ”

"I haven't seen each other in years. But they can't get together if they want to, and they're all gone. Wang Yi replied with a wry smile, after such a long time, I still can't forget it.

"Can you tell me about it?" Zhou Yu was silent for a moment, but he still couldn't help the curiosity in his heart.

It's a painful time, at least Wang Yi doesn't want to think about it. If he hadn't seen this photo today, would Wang Yi never have remembered those past events? The answer is no. Sometimes memories are like appendages, pulling you into the abyss of pain over and over again. If it weren't for that, wouldn't everything be different? Maybe, maybe not? Wang Yi was silent because he didn't have an answer.

In September 2006, it was the time for college freshmen to report, if memory serves. The Department of Economics and Management of Changling University has two dormitory buildings in the dormitory, and the male and female dormitories are only ten meters apart, because they are all freshmen. At this time, there are 6 people sitting around the boys' dormitory 602, introducing themselves to each other, and the next 4 years will be spent together. It can be seen that everyone is very happy, out of their parents, out of constraints, out of the original familiar place, and coming to Changling City, everything is so new.

"My name is Li Fei, I am from Zhouchuan Province, and I am 20 years old this year. It's a pleasure to meet everyone, and I hope to take care of you more in the next 4 years" Li Fei is 170 tall, looks quite handsome, and has a dimple at the corner of his mouth when he smiles. After that, sit down and wait for the next roommate to start introducing yourself.

There are six people in the 602 dormitory, and everyone started the age ranking after introducing themselves, Wang Yi ranked third, and Li Fei ranked fourth. Chen Xi and Cai Yong are the eldest and second. Zhou Jie is the fifth, and the youngest is Han Chengmin. Everyone is young, so they quickly got together, and this dormitory is often joking, and they get along with each other very happily for half a year after the start of school. Then on April 15, 2007, everything changed.

Wang Yi still remembers his mood, doubts, anger, sadness, and unspeakable pain that day. At 18:20 on the evening of the 15th, Wang Yi was walking back to the dormitory after dinner, and the playground was full of men and women, chatting and frolicking. But at this moment, they did not know that a darkness was sweeping in.

"Third, where are you? Hurry back to the dormitory, the second child has an accident. The anxious voice of the boss Chen Xi came from the other end of the phone, I have known each other for half a year, and I have never seen the boss who has always been calm and calm have such emotions.

"Okay" Wang Yi hung up the phone and ran towards the dormitory building, what happened?

At this time, the entire 6th floor of the boys' dormitory was already overcrowded, and from time to time someone was pointing and muttering something. Wang Yi's heart was cold, and he squeezed through the crowd to the door of the 602 dormitory, and saw Chen Xi, Li Fei, Zhou Jie, and Han Chengmin all with pale faces, staring intently at the dormitory with glasses. Before Wang Yi could look inside, he heard a young woman's voice: "The deceased, Cai Yong, male, 21 years old, should have died between 17 and 18 o'clock today." The victim was directly preliminarily judged to have died of poisoning, with a purple complexion, crooked fingers, conjunctival hyperemia, and mucosal congestion and edema of the nose and clasp cavity. There was a violent struggle before he died. Wearing a basketball uniform, he should have just come back from exercise. I suspect he was poisoned by drinking this cup of tea. As for the specific substance poisoning, we have to go back to the test to know. ”

Boom, how can this be? Wang Yi's head suddenly went blank, and there were still roommates who talked and laughed at noon, and now they are separated forever. Wang Yi turned his head to look at the room, and the dormitory was in a mess at the moment. Cai Yong was lying flat on the ground, his eyes were furious, looking at the ceiling, his facial expression had already been distorted into a human shape.

"Wang Yi, haha, I have good news for you, Chen Miaomiao, the flower of the Department of Information, agreed to go on a date with me at night. What do you think? Brother, it's amazing. Wang Yi's mind was still echoing with the last words that Cai Yong said to himself at noon. Awesome", Wang Yi responded psychologically.

"Which of you is Cai Yong's classmate roommate?" It was a young policeman who spoke, his face was solemn, and it was not unserious for such a thing to happen at Changling University. After listening to the forensic doctor's account, he turned to the onlookers at the door and asked in a deep voice.

"The five of us are Cai Yong's roommates." Han Chengmin looked a little nervous, pointed at Chen Xi and said.

"Very good, you come with me, I have some situations I want to know from you, don't be nervous." After speaking, he continued to command a 170-tall, slightly chubby police officer: "Ji Min, you evacuate the students and ask them not to spread the word so as not to cause panic among too many people." After speaking, he didn't wait for him to answer, and walked out first. Wang Yi, Chen Xi and others followed one by one.

Drink poison from a teacup of water? Isn't that teacup the boss? In the dormitory, only the eldest likes to drink tea. If he was poisoned by drinking tea, how would the murderer know that Cai Yong would drink tea? Could it be that the murderer's target was not Cai Yong, but Chen Xi? So Cai Yong is manslaughter? Since the murderer dared to kill someone in the school, he must have a lot of determination. If my guess is correct, then will the murderer find another chance to kill Chen Xi next? Wang Yi followed behind the policeman, his mind constantly thinking.

At this time, the sky was gray, which was the prelude to the storm and the prelude to the darkness of 602. So what awaits them? Death? Fear?
