Lin Wenzhou was a little strange after making the call, why Ling Shuanghua's voice was a little sullen, and then he remembered that he seemed to be a little unhappy with the eldest lady last night, he never held a grudge and forgot it just now.

While waiting, the three of them casually found a classroom to sit down and chat, in fact, it was mainly Wei Qingying and Qi Yueyi chatting, Lin Wenzhou listened honestly on the side, and the two of them chatted for a while and began to study the box seriously.

The box was very exquisite, in Qi Yueyi's words, it looked like it was made of silverware, but it seemed to have a small mechanism, and if it was not opened in the correct way, it could have very bad consequences.

Lin Wenzhou watched the two of them play the puzzle, it was really amazing, the two girls were fast, basically they saw them come out with a complete picture in three clicks and two clicks.

He wiped his sweat, this puzzle level and his mother have to fight, I remember that once my mother and Aunt Chenxi were bored to challenge the puzzle game, that time he and his father were frightened......

The problem is that there is no movement in the puzzle box, so Qi Yueyi frowns and tries a new combination method, but no matter how she makes it, other ways can't completely spell out a picture, but Qi Yueyi still has a calm face and no very deflated expression.

Wei Qingying also fiddled with it a few times, and finally came to the conclusion that it was really the last piece of the puzzle, and if it was put on, it would be able to be opened.

At this time, there was a sudden sound of footsteps, and Lin Wenzhou knew that one of them should be Miss Ling as soon as he heard it.

He pushed the door out with two beautiful girls, and sure enough, he saw Ling Shuanghua walking in the front, with a thief-eyed guy in the back, who was looking around, and there were two other people at the back, one old and one young, and later I heard her introduce the partners of the detective agency, Lu Linrui and Kang Mengbin.

Ling Shuanghua explained: "Picking the lock is not a thing on the table, there must always be someone to watch and not let the idlers wait, although there is usually no one here, but she is not afraid of 10,000 just in case, she plans to let those two people pretend to be police officers to stop other students." ”

Lin Wenzhou glanced at the eldest lady with some surprise, and couldn't see that under her cold appearance, her mind was still quite delicate, and she acted in a bit of a leadership style.

I heard that the thief was the first thief in Cheongju, called Li Bingbing, nicknamed 'someone's shadow'.

Li Bingbing seemed to have special respect for Ling Shuanghua and Lu Linrui, and after listening to Lin Wenzhou's goal, he looked at the door with disdain, probably feeling that his attack on this lock was somewhat overkill.

He skillfully took out a tool kit, which was full of all kinds of strange-shaped tools that Lin Wenzhou had never seen before, and then he squatted at the door of the grocery room and began to pick the lock skillfully.

Taking advantage of this opportunity, Lin Wenzhou briefly explained the situation to Ling Shuanghua, saying that the moment the eldest lady saw him when she first came, although it was cold on the surface, in fact, the shadow told Lin Wenzhou that she was in a good mood.

However, this good mood disappeared after she saw Qi Yueyi's appearance......

Finally listened to what Lin Wenzhou said, and knew that it was Qi Yueyi and Wei Qingying who were together at first, not dating someone, which made the eldest lady a little happier, and she said coldly: "That woman is quite enthusiastic......" Because Lin Wenzhou pulled her aside to speak, she was not worried about being heard by scouts.

Lin Wenzhou found it very strange, as if she always had some opinions about Qi Yueyi.

Just as he was thinking about it, he heard Ling Shuanghua say, "Go and cook for me in the afternoon, I have something to say to you." ”

Lin Wenzhou nodded, and suddenly that Li Bingbing muttered: "I'm, it's actually a triple chain!" ”

Wei Qingying, who was watching his movements curiously, and even felt like he was studying humbly, said strangely: "Master Li, what is the triple link?" ”

Li Bingbing saw that he had the opportunity to show off his professional knowledge like a beautiful girl, he was overjoyed, and talked endlessly, to the effect that this kind of lock is very rare, even if you take the normal way, you need three keys to open, and there are probably only a few people in Qingzhou who can have this ability to open the lock, and you are definitely lucky to find me.

Wei Qingying and Qi Yueyi glanced at each other, and the former continued to ask without hesitation: "Master Li, how many people might be able to open this lock?" ”

Li Bingbing thought for a while and said: "Except for me, it's probably just those two people who are okay, one is called 'God's Left Hand' and the other is called 'Tianyan', both of whom are old-timers in our industry......"

Lin Wenzhou quickly explained to Ling Shuanghua that this lock had been pried open not long ago, and the eldest lady turned pale and quickly made a call to Lu Linrui, who was guarding outside, and asked him to find a way to find the two old thieves.

Seeing that Li Bingbing was boasting about himself while his fingers were working hard with various tools, Wei Qingying and Qi Yueyi, two beautiful girls, watched his movements with wide eyes, as if they were secretly learning, I really didn't understand how they were interested in this special craft.

A few minutes later, I heard Li Bingbing shout with joy: "It's done!" ”

As soon as he turned his hand, there was a sound of Kala, and he gently opened the door, and he took the lead and tiptoed in, as if his footsteps were not sound at all, it was definitely a professional habit.

There were no windows or lights in the utility room, and even in broad daylight, it was pitch black inside, which made several people feel a little depressed.

The quietness of the utility room in the dark makes people's hearts furious, but fortunately, the 'shadow of someone' Li Bingbing has all the tools on him, and he took out a small flashlight to illuminate the surroundings.

Following the faint light of the flashlight, Lin Wenzhou looked around cautiously while walking into the house, the utility room was very small, no more than 30 square meters, located on the north side of the fourth floor, next to the stairwell.

The entrance is located at the westernmost point of the south side of the utility room, and the room is about four meters wide from east to west and eight meters deep from north to south.

There are six rows of shelves on both sides, one for each row, leaving a narrow corridor in between.

The shelves are messy with all kinds of sundries, worn-out tools, brooms, gloves, ropes, and tattered clothes, and even a few hard hats, Lin Wenzhou even found that there are several books on a shelf, all of which are old antiques, and as time goes by, the damage is not good, and it can only be vaguely seen that one of them is a dictionary and a reference book.

On the northernmost side of the utility room was a table, which was empty, and Lu Linrui, who was called up to help, squeezed to the front and carefully illuminated it with a flashlight, and soon he said with some surprise: "Mr. Ling, it's a little small!" ”

Ling Shuanghua and Lin Wenzhou also walked over, only to see Lu Linrui, a retired veteran criminal policeman, pointing to the table and saying, "The thickness of the dust on this table is not consistent, judging from the dust marks, it is obvious that something has been placed in the middle." ”

Wei Qingying walked to the front, looked at the table, stood there and thought for a long time, and finally her eyes flashed! Then Wei Qingying returned to those shelves with a hint of excitement, and seriously looked at the various old items on them one by one.

Looking at these tattered and disorganized things, her eyes became more and more excited!

Lin Wenzhou wanted to say something, so he heard Qi Yueyi say lightly: "Qingying also thought of it, I understood as soon as I came in and saw these things just now, these are relics......"

As soon as these words came out, except for Li Bingbing's indifferent look, the faces of several other people changed suddenly, Lin Wenzhou reacted the fastest, he suddenly understood what Yue Yi meant, and said a little excitedly: "These things are the relics of the seven missing workers?" No wonder there are such hard hats that are only used on construction sites! By the way, these yarn gloves, these books......"

Wei Qingying smiled and said, "It shows that there are also studious people among those seven people, and they are also reading in their spare time......"

At this time, Lin Wenzhou suddenly added: "Did Zhang Sicheng see this room that night......

Qi Yueyi said seriously: "Let me make a bold guess, on the night when Gu Jiajia and the others pretended to be ghosts, maybe there were not only a few people on the fourth floor who everyone knows now, but there was also a person who was hiding here at that time...... Of course, what he's doing here we'll talk about later. ”

She paused and continued to explain: "Then when Zhang Sicheng fell to the ground, he happened to lie on the ground and looked west, and this magical angle allowed him to just see things that he couldn't see under normal circumstances...... For example, there is a faint light in the crack of the door below, maybe it is candlelight......"

Lu Linrui immediately interjected: "It is very likely, you look here, there is a trace of the candle after it burns out......

Qi Yueyi nodded and continued: "Maybe he was not the only one who discovered the light at that time, I think there should be Gu Jiajia, because the other people rushed directly out of the classroom door, and she was the only one who kept walking from west to east...... However, she should have told Chai Simin about this discovery. ”

Ling Shuanghua couldn't help but ask: "If there was this person hiding in the grocery room at that time, then how could the police not know ......?"

Lin Wenzhou explained: "This is simple, after Gu Jiajia escaped, that person also took the same method, jumped directly and bypassed the camera and ran away." ”

Wei Qingying also added: "But they can't let the school know about this major discovery, for fear that the school will move the things inside in time, so Chai Simin took the risk to kill Zhang Sicheng." ”

After Lin Wenzhou listened to Wei Qingying's words, his gaze returned to the empty table at the end of the room, and said to himself: "Speaking of moving things, just now Lu Lao said that there was something here, and now that Yue Yi has reminded me, I kind of understand, relics, candles, what did you think of?" ”

Lu Linrui almost blurted out: "Lingtang! ”

Lin Wenzhou nodded and said: "I think the same as Lu Lao, the real function of this utility room should be a mourning hall, someone is here to mourn, the object is obviously the seven migrant workers, you said that there should be a spirit tablet on this table...... )
