After Jiang Li left, a soft sobbing sound suddenly sounded in the library, and Qin Zheng and Chen Lang turned their heads in shock at the same time, because the source of the sobbing was none other than Lin Xiyu. Pen, fun, pavilion www. biquge。 info

"What are you looking at me for? Lin Xiyu's two eyes were red from crying, his little nose was still twitching, and he spoke in a thick nasal voice.

"Are you crying?" Qin Zheng frowned, and he had the urge to reach out to help Lin Xiyu wipe away his tears, but he held back.

"Nonsense!" Lin Xiyu wiped his tears with his sleeve and wiped them away, but his eyes were even redder, "Don't you think what Dean Jiang said just now is very touching." ”

Of course, it is touching but they are men, Qin Zheng and Chen Lang stopped looking at it at the same time, and began to study the table of the picker.

"Speaking of which, what clues can there be?" Chen Lang looked at it casually, mostly borrowing records, and some tools for repairing books.

"Did you hear anything from Dean Jiang's words just now?" Lin Xiyu adjusted his mood and joined the army of flipping through.

And Qin Zheng's attention at this time fell on a small blue potion.

"Dean Jiang said that he must catch the little cub who killed him for the sake of the bully, doesn't that mean that the senior is not a murderer!"

Originally, they were going to secretly look for the senior, but now it seems that they don't need it.

"Also, how can the fifth floor of this library be so easy to enter, even if you kill the bully, it won't be useful, it's really strange. Chen Lang's babbling words surprised Qin Zheng and Lin Xiyu at the same time.

"Miss Lin, how do you get into the fifth floor of this library?" Qin Zheng looked at the stairs at the end of the library, and seemed to see a person who had walked there.

"Except for the dean and a few teachers, only those fifth-graders can go up to the fifth floor, because there is a ban between the fourth and fifth floors, and the purple uro flower on the chest of the fifth-graders has a special keystone, so only fifth-graders can pass it. ”

"The key stone is on the clothes?" Qin Zheng walked up the stairs layer by layer, and when he walked to the fourth and fifth floors, he really touched a transparent wall, and the prohibition was good.

"Yes. ”

"Isn't it true that anyone can go up to the fifth floor as long as they wear this dress?"

"That's not it, isn't there a librarian watching, who is not a fifth-grade student of him......" Lin Xiyu said as he spoke, suddenly paused, the three of them looked at each other, and then turned around and ran down the stairs at the same time......

"Report lost?" The aunt in the living area also went up, and she seemed to be a little old, she held her glasses in one hand and opened a booklet with great difficulty, which recorded the loss of the students in the past two days.

"What did you just say, what are you looking for?" Auntie's memory may not be very good, and after looking at it for a while, she forgot what she was looking for, so she looked up and asked Qin Zheng and the three of them.

"Auntie, help us find it, has anyone lost their clothes in the past two days?" Qin Zheng asked while looking at the booklet in his aunt's hand, sweating slightly.

"No one has lost their clothes in the past two days. "The aunt held the reading glasses up and down for a long time, but did not find anyone who reported the loss of the clothes.

"How could it be!" Chen Lang simply poked his head over and searched for a long time, but indeed no one reported the loss of clothes.

The three of them walked out of the life management department, and suddenly felt a little confused, and the clues seemed to be broken all of a sudden.

"Three possibilities. Qin Zheng pondered for a long time, "One is a teacher who can go up to the fifth floor to commit a crime, one is a person who lost his clothes and did not report the loss, and the other is a fifth-grade student who did this." ”

"I think the second one is more likely. Lin Xiyu pondered for a moment and said, "After all, for fifth-grade students, losing a school uniform is a big deal, and it is possible not to report it." ”

At this time, a few students walked past Qin Zheng and them, talking and laughing, Qin Zheng's steps suddenly paused, and he turned around and looked at the back of one of them.

"What, do you like her?" Lin Xiyu pursed her lips, the person who walked past them just now happened to be Wind Chime, as well as a few of her friends.

Laughter, warblers and swallows, young and beautiful girls, is indeed a landscape that can make people stop.

Qin Zheng's eyes were still staring at the direction where Feng Chime was leaving, and he said in a deep voice, "This road, how many people walk at night?"

"The library closes late, and there are still a lot of people coming in and out, and there is a practice ground next to it, and many people who practice late want to go back to the dormitory, this road is the only way to reads;. "Chen Lang is really powerful, he has only been in this school for a long time, so everything is clear.

"Does everyone know the fifth grader?"

"I can't say every single one, it's not clear how many new students there are, but the old students all know which ones they are, after all, there are only six or seven fifth-graders in the entire school. ”

"Wouldn't it be noticeable if someone who wasn't a fifth-grader walked down this road in a purple Ulau uniform?"

"That's right!" Chen Lang slapped his palm, and for a moment he seemed to understand something, and for a moment he seemed to become very puzzled, "No, the purple pulau mark is specially made, and it will self-destruct once it leaves the robe, if it is not worn on the body, then how did that person bring the clothes into the library? Could it be that it was put in the package." ”

"Unlikely. Lin Xiyu waved his hand, "There are practical classes here every day, so every teacher will ask students not to carry packages, very few students will carry packages with them, besides, he must be careful when he wants to do this kind of thing, how can he bring a package to attract attention?"

Just when Lin Xiyu and Chen Lang were struggling with a clue, Qin Zheng suddenly pointed to the back of a girl beside Feng Chi'er and said, "That person, her clothes, have been re-sewn." ”

"The school uniforms issued by the college have always been on the large side, and among the girls, there are not a few who re-sew the school uniforms, is there anything wrong?" Lin Xiyu was puzzled, her figure was tall, so the college uniform was just right to wear on her body, but for some petite girls, this robe was indeed bigger.

"Because she has a problem. Qin Zheng said very seriously, and he was very sure.

It turned out that just now, when Feng Chime and the girls walked past him, he saw at a glance that the corner of the girl's skirt was stained with a faint touch of blue.

He knew what it was, it was the spiritual glue that was used to edit books from time to time, it was easy to color, and it was difficult to wash off, because he used the little finger of his right hand to apply this glue all year round, so his little finger turned blue that could not be washed off.

The corner of the girl's skirt is this blue that can't be washed off.
