crime scene

Su Nian was directly arranged to live in the postgraduate dormitory. The single room is very spacious, but the dormitory fee is a bit higher than that of undergraduate students.

He didn't dare to imagine Xie Qian's current situation, but if he could control his thoughts, there probably wouldn't be so many people crying for their parents because of a broken relationship.

He hadn't eaten for two or three days. He knew that he would definitely go to the hospital if he kept going on like this, so he had no choice but to try to force it down, but he vomited it all up. In the end, he had to see a psychiatrist, and after taking some medicine, his body recovered. Slowly recover.

The old professor's physical condition was also not very good, and he only brought three graduate students. This kind of person at the township level generally would not teach undergraduates, so his courses were allotted to three graduate students.

Sometimes the three senior brothers would be lazy, and Su Nian would take a group of undergraduates with them.

"Today, your teacher is lazy and committed cancer. I will teach a class."

There was a discussion in the classroom, but Su Nian didn't pay attention, and raised her head to look around.

This is how Lu Zitong was discovered by Su Nian.

They were classmates in high school for three years, and at a glance, Su Nian found that Lu Zitong was sleeping soundly in the last row.

"The last row sleeps in the same way, wake up, the cafeteria downstairs is open."

When Lu Zitong saw Su Nian standing on the podium, he was in a daze, and he never dozed off during the whole class. He wanted to ask him after class, but a group of little girls surrounded him. .

If you have any questions, please ask for your mobile phone number, WeChat ID, Penguin account, email address and Weibo, and you can ask for everything you can ask for.

His class is so-so, but his appearance is there.

It's so pretty, you can really do whatever you want.

Lu Zitong didn't find a chance to talk to him until noon, and Su Nian just bowed his head to eat without saying anything, and only answered some basic questions, such as where he lives now.

He didn't say a word about Xi Qian, Lu Zitong guessed what happened in between.

"Let's go out to dinner Saturday night! Your treat!"

"If you can finish the homework I left you."

"It's all buddies, just tell me the answer!"

"You copied my homework in high school."

Lu Zitong smiled a little embarrassedly, "Then you are the one who has to come to class next week!"

That's right, Su Nian is just a substitute, as for his homework, the next class is not up to him.

On Saturday night, Lu Zitong found a roadside stall and kebabs on the side of the road.

Su Nian didn't drink at first, Lu Zitong tried his best to persuade him, he wondered if the three good students would drink, but Su Nian blushed immediately after drinking a bottle, his cheeks were rosy, unexpectedly cute.

Su Nian started to cry when the second bottle was put down, lying on the table without saying anything and just crying.

The owner of the barbecue stall asked him if he was broken in love, Lu Zitong nodded, probably, it must be torture to fall in love with someone as bored as Su Nian.

Lu Zitong had no choice but to settle the bill and take him back to the dormitory.

Su Nian seemed to be addicted. He dragged Lu Zitong to drink when he had nothing to do, and cried when he was drunk. This state lasted for half a year. Su Nian got caught up in the matter.

But he never knew that Su Nian had such a fondness for candies. He may have no money in his pocket, but he can't live without candies. There are all kinds of candies, lollipops, soft candies, hard candies, and plum chocolates.

When Su Nian was in the second year of graduate school, Lu Zitong was successfully admitted to the graduate school of the school, and in the first year of graduate school, he squeezed into the same dormitory with Su Nian, euphemistically called "living together".

Only then did he realize that Su Nian didn't sleep well almost every night, and he could often hear crying when he fell asleep at night, but he was like a normal person during the day, doing whatever he was supposed to do.

What Su Nian never stopped were love letters. Lu Zitong often brought him love letters for undergraduates, but Su Nian never read them. He just put them in a drawer and let them sleep forever.

Valentine's Day is also greeted with lots of chocolate.

Lu Zitong wondered why he couldn't receive a love letter even though he was not bad at all.

Curse him for eating candy and breaking his teeth!

His little prank was really useful, one day Su Nian really came back clutching his teeth, that day he was not well, sat on the bed in a daze for the whole day, complained about toothache and refused to go to the doctor.

"Why don't you go to the hospital?" Lu Zitong persuaded patiently again.

"It's okay, it's just getting angry." Su Nian replied, "Go and buy me an ice cream."

Lu Zi gave him a blank look, and obediently went downstairs to buy ice cream.

It took a long time for him to go, but Su Nian was not in a hurry, when he came back, the ice cream had already started to melt.

Su Nian took a small bite and put it on the compressed nerve to relieve the pain, while Lu Zitong sat on the side drinking a drink and looked at him.

"I just heard that a student in our police academy died. He was an intern who had not been out for an internship for a long time. It seems that he was killed. The city bureau is very serious about it."

"What is the reason?"

"Looks like cyanide poisoning."

"Where is the source of the poison?"

"Where do I know this, but I'm just wondering, a police school intern who has just stepped into the society will not have any enemies, and there will be no one who can't think of murdering the police, right?"

Su Nian nodded, "In all murder cases, women are not as strong as men in stature and strength, so the possibility of choosing to kill with poison is very high, but we don't know the source of contact and the method of poisoning, so it's not easy to do conclusion."

"But I heard that he died in the dormitory. His three roommates said that he fell down suddenly and couldn't get up." Lu Zitong stood up and grinned, and slowly approached Su Nian, "He loves you just like you... Eat sweets!"

"How do you know so much inside information?" Su Nian reached out and pushed him away.

"I heard it from two teachers in the cafeteria downstairs."

"This can only show that the first team is slack, and they can't even keep the case confidential." Su Nian complained, "Did you touch anything before you died?"

"I don't know, I think it should be because I didn't touch it, otherwise how could I not find out the source of the poison?"

"You may not be able to find out if you touch it." Su Nian gave up the pain relief and ate the ice cream bite by bite. "However, drug testing belongs to the scope of work of the forensic department."

"yes…"

"Let's go check it out."

"What?"

"Investigate the case."

Lu Zitong really admired him, saying that investigating a case is investigating a case, and he really regarded himself as a detective.

Lu Zitong ran outside with Su Nian all morning, and didn't follow when there was class in the afternoon, but that night Su Nian came back as if he had seen a ghost.

"What happened to you?" Lu Zitong asked a little funny.

"I see, it's a dental clinic." Su Nian didn't answer his question directly, but said to himself, "You said that he loves candy as much as I do, and all his activities before the crime were very different. The special thing is that he went to the dental clinic."

"Admiration." Lu Zitong applauded involuntarily, "And then? Did you go to the dentist?"

Su Nian nodded, "But the doctor in charge didn't fill in the medical records for me, which is very strange, and then I became more sure of this, so I came back so as not to startle the snake."

"Amazing." Lu Zitong was proud of having such a witty and brave roommate, and was determined to blow him up.
