Lin Jin'er thought about it. At this time, the murderer must have wanted to be alone and destroy some of the things used in the crime by the way, but he didn't expect that except for Bai Zechen, who expressed his willingness to stay, the other people were a little frightened, but they were all ready to get up and leave and go back to their rooms.

It seems that this method is passed.

"Professor Lan, did you bring super glue? When I came out just now, I was in a hurry, and I broke the armrest on my suitcase, and I wanted to make up for it. ”

"Yes, I'll give it to you. Linkaka, you really worked hard today, if it weren't for the fact that you were the first to find out, maybe someone else would have destroyed the scene...... You're a very special kid to be able to keep so composure in such a situation. ”

Professor Lan pushed his glasses, handed the glue to Lin Jin'er's hand, and then exchanged a few more words. Lin Jin'er looked at him with such a calm expression, and she really admired it in her heart. He decided that no one now knew that except for Ye Lanxi, who had died, and Zhou Tiantian, who had died, he was actually the target of the deceased's blackmail, that is, one of the biggest suspects.

After returning to the room, Lin Jin'er looked at the glue in her hand in a daze, and after a while, she turned around and began to rummage through the more suitable size sealed box.

Yes, Lin Jin'er was originally a comic book author, and in order to be able to write better scripts, she usually read some very strange books, including a method of using super glue 502 to extract fingerprints. Although the memory is gone, these strange common senses have been recorded in her brain, which has a large brain circuit.

502 is the theme of ethyl a-cyanoacrylate, and according to certain steps, fingerprints containing grease can be smoked out in a sealed box.

Lin Jin'er proudly praised herself a few words, and then carefully put the two bottles of drinks collected in the restaurant in the box......

"I'll see how long you can endure!"

He sat in front of the door and stared at the movement of the restaurant downstairs. She communicated with the cook earlier, hoping to help her find the real murderer, and this mustache is obviously a detective fan, not only did not question Lin Jin'er at all, but was unusually cooperative, and even wanted to give Lin Jin'er a hug and raise it high.

Time passed minute by minute, and Lin Jin'er, who was already a little sleepy, finally heard a voice from the corridor, and then the figure appeared in the hall.

And she guessed correctly, this person was Professor Lan.

I looked left and right, and then carefully stared at each door on the second floor, and after about ten minutes, I walked slowly and methodically in the direction of the restaurant.

Standing in front of the table where Ye Lanxi fell, looking at the chef who was still asleep with a coffee cup in his hand not far away, Professor Lan cautiously began to observe the drinks on the table.

This is Lin Jin'er specially asked the cook to do, after taking away the drink bottle at the time of the crime, she asked the cook to help put two identical bottles, ready to see who will come here later to take away the evidence of the crime.

Ye Lanxi has no external injuries on his body, if he quarrels and fights, he will also be heard by others, although he has not carefully checked whether there will be traces such as pinholes on his body, but after all, it is not a simple way to kill, and for the students in these clubs, or this professor who is full of thoughts about how to calculate the location of the Wishing Stone, poisoning is the easiest and least likely to make mistakes.

Lin Jin'er, who held her mobile phone and cast a shot at the door and took pictures of Professor Lan, now wants to scold the street. Because of this Professor Lan, he stopped at the table for about ten minutes, and didn't pick up the drink, but left quickly.

"Weird, hey...... This old fox! Could it be that he noticed that someone was watching him? ”

Lin Jin'er shrank in front of the door for more than twenty minutes, her body was already a little sore, and she was ready to get up and move, but she heard the sound of another door opening.

It's hilarious!

Lin Jin'er had to maintain this awkward posture and continue to record with her mobile phone.

The sound of opening the door this time is not far from Lin Jin'er, it seems that this time it is a girl.

As she thought so, her true face slowly emerged in the hall.

Is it Zhou Tiantian?

Lin Jin'er frowned and thought, although this Zhou Tiantian was also blackmailed by Ye Lanxi, she basically had no chance to commit a crime, what did she want to do when she came out?

Her eyes followed her footsteps and slowly moved to the restaurant. With the same vigilance as Professor Lan, he also stood at the table looking at the two bottles of drinks, and also stood there for about ten minutes before returning to his room.

However, unlike Professor Lan, Zhou Tiantian's expression. There was some sadness mixed with relief, which was inversely proportional to Professor Lan's completely relieved expression.

"System-kun, come out."

- What do you do here without sleeping at night?

"I'm collecting everyone's post-incident situation."

- Isn't there such a thing as surveillance? Do you want to pat it here with a little phone?

"You're not kidding, are you? If the owner comes back to check the surveillance, I won't solve the case, so won't I be able to complete the task? ”

-You are now a detective and you only need to solve cases without sending them to prison.

"Damn, why didn't you say it earlier! Forget it...... I'll get down to business with you. Can you do me a favor? ”

Lin Jin'er originally thought that since this system Jun has no entity, he should be able to see the situation in each room, but without waiting for Lin Jin'er to say it, he asked him not to use the plug-in to send it away.

Helplessly, she can only rely on her smart little head and the fingerprints smoked out of the sealed box.

"Wait...... I saw the fingerprints, and I didn't know who they belonged to! ”

As soon as she thought of this, Lin Jin'er began to curse the irresponsible system gentleman again, and in the end, she was really helpless, so she could only continue to squat in front of the door to see if there was anything new.

The sky outside was already a little dark, and it looked like no one else had been seen until at least half past four in the morning.

Now Lin Jin'er has roughly confirmed that the murderer who poisoned her is Professor Lan, as for why Zhou Tiantian came out to check, probably because Professor Lan asked her to do this, otherwise, why, the person who blackmailed her is obviously dead, but he still has a sad face?

Perhaps, she is now already worried about herself, worried that this ruthless man will also kill himself in order to make this matter a secret completely.

Lin Jin'er, who was sitting on the small bench with her cheeks in her hand, slowly began to doze off in the style of chicken pecking, and finally succeeded in dreaming of a sweet dream.

Until dawn, the rest of the people had already gathered in the hall, waiting for the police to deal with this time, but Bai Zechen woke up anxiously with shouts and slamming doors because he had never seen the figure of 'Lin Kaka'.
