"Are you jerking?" Su Yong asked.

Zhang Kexin said excitedly

"Didn't I find the Swarovski gift bag in Director Zeng's office, Hezi said before that Qu Lian has a black swan necklace, isn't the black swan a classic Swarovski?"

Guo Hongyi and I were excited when we heard it, the kind of scalp tingling, as if we had seen the dawn in the long dark night, and Su Yong also nodded again and again

"I see!"

I asked Su Yong with a smile

"Brother Yong, you also understand, don't you?"

Su Yong nodded firmly and said

"Hmmm! Qu Lian must be the daughter of Director Zeng's deceased wife's sister, as a sister-in-law, Director Zeng embezzled public funds to buy her a necklace, and the secret was discovered, so he killed people! ”

After listening to Su Yong's impassioned reasoning, my face was full of black lines, and Guo Hongyi fell directly from the chair, Su Yong saw this, and asked in a flurry manner

"Brother Guo, what's wrong?"

Zhang Kexin said while helping Guo Hongyi up

"What's wrong? Still too young to have nothing to do, let your reasoning scare you! ”

"What do you mean?"

Guo Hongyi said after sitting down again

"What do you mean, you don't mean to tease us? Would any uncle-in-law give that kind of stylish necklace to his niece? And he is a teaching director, and he still needs to embezzle public funds to buy a necklace of several thousand? And even if you embezzle the school's public funds, a few thousand yuan, you can get it back, why kill people? ”

Su Yong asked curiously

"What's going on?"

Guo Hongyi shook his head, didn't say it directly, and reminded him little by little

"Brother Yong, what do you think, there is a rumor in the school that Qu Lian was taken care of."

"Ahh

"Qu Lian looks very much like Director Zeng's deceased wife."

"Ahh

Qu Lian accepted Director Zeng's black swan necklace again.

"Ahh

Guo Hongyi finally got impatient and said

"What are you, ahh

Su Yong thought about it, and said with a surprised expression

"You mean, Qu Lian is Director Zeng's lover?"

Guo Hongyi patted his thigh and said

"Thank goodness you finally figured it out!"

Zhang Kexin said with a deep look in his eyes

"It should be Roy, Ke Hezi, and Xia Nanxing who inadvertently broke the private relationship between Qu Lian and Director Zeng, which also explains very well why Director Zeng quarreled with the three of them, and also explains why Ke Hezi's attitude towards Director Zeng is so disdainful, because these three people know this secret, and Qu Lian kills people in order to keep the secret."

I snapped my fingers and said

"I finally remembered where the unnatural place was, and suffocated me!"

Zhang Kexin and the three of them looked at me in confusion, and I explained

"Yesterday morning, when Officer Hu was investigating our alibi about Roe's case, I felt something unnatural, and now I finally remember, Director Zeng said to Officer Hu, 'Qu Lian is not the first discoverer of the case', we didn't say it, how did he know, it can be seen that the only explanation is that on Christmas Eve, Qu Lian had been with Director Zeng all the time, and only rushed back to school the next morning, so Director Zeng would say such things."

As I spoke, I patted my chest and complimented

"Brother Yang, it's good, this kind of detail has been noticed, what a keen insight!"

Su Yong and Guo Hongyi were very unaccustomed to my behavior, and Guo Hongyi said directly

"You don't have to talk about calves here, the child died and you came to milk, if you had thought about it earlier, maybe you would have known the relationship between the two of them, how many detours do we have to take?"

Su Yong also sneered

"Then you still suspected Bai Zhi before, what's going on?"

Hearing Su Yong say this, I was also a little hesitant, could it really be my delusion, I was too sensitive? Bai Zhi is just sad because her friends died one after another? How to explain the contradictions between her and Jiang Junqian's confessions?

I said with some unconfidence

"Maybe I'm thinking too much..."

Zhang Kexin is not as optimistic as we are, and said calmly

"Even though we know these secrets, we don't have any evidence, and there are still many unsolved mysteries, such as how the hell did she get out of Roy's locked room? Also, she asked Bai Zhi to buy her sanitary napkins, what if Bai Zhi happened to have it at that time? And she couldn't judge the time of Bai Zhi's round trip, was the plan too risky? ”

The first case we encountered was the "Walking Corpse" case, when Zhang Kexin almost caused a big incident of an instructor beating a student due to poor thinking, after that incident, Zhang Kexin's mind became more careful than anyone else in the dormitory, and he was calmer, and when we were immersed in the joy of imminent victory, he could always find a problem.

I gritted my teeth, finally made up my mind, smiled with relief, took out the phone, and Zhang Kexin asked

"Who are you calling at this time?"

I shook my head helplessly and said

"Zhang Fan, I've come to this point, I'm really unwilling, but I've really reached the limit, and in the end I still have to rely on the strength of that bastard..."

My tone became a little pitiful in the end, because I really felt that I was pitiful, and I had to give in to fate after holding on for so long, admitting that I still couldn't do without Zhang Fan's help.

After the phone was dialed, I told Zhang Fan in detail about the situation here, and then talked about how the body was found, and the layout of the secret room, when I finished speaking, my heart was extremely conflicted, I didn't want him to solve the problem that I couldn't solve in a few words, but I really hope that he will tell me the answer quickly.

Zhang Fan did not ridicule the case for being too simple, as he used to do, and did not tell me the answer directly, but asked me

"Do you know what the biggest difference between solving a real murder case and the escape room mystery games we used to play is?"

I was a little surprised to hear him say that, and thought to myself

"Zhang Fan is talking about him so much, is this case too difficult for him? No, no, according to Zhang Fan's character, he will not choose this way of evasion, and there is no case in the world that he can't solve. ”

I said

"What is it?"

"It's human nature."

"What do you mean?"

Zhang Fan began to explain slowly

"When we play escape room, we can completely ignore everything else, just think about how to unlock the hidden password, but not in a murder case, it is really a living life that has been taken away, so we must take humanity into account."

Rarely, Zhang Fan's tone was like giving me a lecture when I was a child, and as I grew older, the intellectual gap between the two of us grew wider, and he gradually began to be unable to stand my stupidity, and spoke to me less and less often in this tone, replaced by all kinds of lessons and even insulting language.

I miss it, but I still don't understand what he's talking about

"I still don't understand."

I originally thought that Zhang Fan would be impatient, but he still didn't, and said calmly

"Do you remember the eight purposes for which the Chamber of Secrets was created?"

I said quickly

"I remember, but I can't imagine what the murderer is for."

Zhang Fan's patience this time was really good, and he continued to say unhurriedly

"It's very simple, because those eight purposes are only limited to mystery novels, because every murderer in mystery novels is calm to the point of impossibility, they can perfectly implement the murder plan according to their previous expectations, but reality is not, no matter how much you hate another person, no matter how many times you fantasize about killing each other, when you really wave the butcher knife, when a living person dies in front of him, the murderer can't be calm, he will be full of fear, according to your description, the murderer should be temporary, Then the level of fear he was at that time is not what we can imagine, so this case belongs to the ninth purpose, no, to be precise, the reason. ”

"What is it?" I asked hurriedly.

"It's helpless, it's no choice."

It's rare that this time it was Zhang Fan who made me impatient, I said impatiently

"Can you finish it in one go, how did I listen to the clouds and mountains and fog?"

"I'll stop it."

I said with a dumbfounded voice

"Are you Zhang Fan? I just felt that something was wrong, and if I had known the answer, I would have said with disdain, 'You don't know this?' And then then he crackled and explained things to me, and then mocked me again, and now not only did you not, but you said that the point was over? ”

Zhang Fan was amused by my tone and said with a smile

"It's still human nature. This case happened the night before yesterday, but you only called me this evening, it can be seen that you have been entangled for a long time, and you don't want to rely on me, I don't know if you want to prove yourself, or if you are told by a friend that you will only rely on me, but I know that you really want to solve this case yourself, as a friend, how can I go against your will? ”

Now I realized that Zhang Fan had just hinted at me nonsense, what was the purpose, I wanted to say thank you to him, but the relationship between the two of us, these two words, I really can't say it, just when I was silent, Zhang Fan said

"I've told you so much, and if you can't solve this case yet, I'm going to be disappointed."

After finishing speaking, he hung up the phone without warning, and after I put away the phone, Guo Hongyi saw me like this, and asked with some disbelief

"What's the matter, Zhang Fan doesn't know the answer?"

I shook my head and said

"No, Zhang Fan should know the answer, he gave me some hints, but he said that he hoped I would solve the case myself."

Zhang Kexin then asked

"What hint did he give you?"

I said thoughtfully

"He said that human nature, murderers are very afraid after killing, and he was forced to create a secret room."

Obviously, Guo Hongyi and Zhang Kexin couldn't understand the meaning of this sentence, Guo Hongyi scratched his hair and said

"As a last resort? How do you say that it's like creating a secret room and playing with it? ”

I grew up, not to mention killing, I saw that the killers all took a detour, and I couldn't understand the state of mind of the murderer when I killed someone, I slowly closed my eyes, and forced me to fantasize, if I killed Roy, what would I think, at this time Su Yong covered his stomach and said

"Oops, no, my stomach hurts, I need to go to the bathroom."

I bit my nails and began to meditate

"What would have happened if I had killed Roy? I've killed someone, my life is over, I must not be discovered, I am going to get out of here, I am going to escape from the room, no, I can't let people see the body, I have to lock the door, the key is still in my hand, what am I going to do? ”

Then I recalled the details of the case

"Roy is left-handed"

"The body clearly showed signs of being moved."

"Mysterious K, wait a minute, what does K mean?"

"I see!" I shouted loudly, Guo Hongyi and Zhang Kexin stared at me, and I didn't pay much attention to them, muttering to myself in disbelief

"Impossible, the murderer turned out to be him? If it's him, then Kehezi..."

Just as I was once again confused, Su Yong in the toilet shouted

"Damn! Why is the toilet mat wet? ”

Guo Hongyi said embarrassedly

"I'm sorry, Brother Yong, I accidentally got it when I washed my socks in the morning, haven't you done it yet?"

"Of course not! You can't pay attention! ”

I jerked my head up

"Toilet mats? I seem to have had a toilet mat before that made me very concerned, what is it? ”

After a minute, I lowered my fingers, and by this time I had figured everything out

"Why did the murderer kill Roy, what the hell does the mysterious K mean... Everything, everything, all understood. ”

Zhang Kexin and Guo Hongyi looked at me and asked softly

"Yang'er? Do you know how Qu Lian left the secret room?

My eyes were full of sorrow, and I said very sadly

"If that's really the case, then this case is really sad."

"Did you really think of it?"

I nodded, for the first time I felt sad about solving a puzzle.

Zhang Kexin asked

"Then should we call everyone together now and identify the murderer?"

"yes, that's fine."
