After entering the warehouse again, the location of most of the materials inside had changed, looking at this scene, I couldn't help but be a little angry, frowned, and muttered a word

"Hey, the location of things has changed, it seems that even if there were any clues originally, it is estimated that they are gone now."

Seeing that I had some negative emotions, Guo Hongyi said in a comforting tone

"There's no way around it, after all, the practical activities have to continue, and it's normal to move things in here, but when you went to bed this afternoon, we also double-checked here, and there really wasn't anything suspicious."

I nodded and smiled

"This is natural, after all, finding clues is what Brother Guo is best at, since Brother Guo hasn't found it, it is estimated that I won't be able to find anything even if I dig three feet here."

Su Yong heard me say that he was digging three feet into the ground, and quickly took a few breaths, and Zhang Kexin asked when he saw this

"What's wrong? Is your nose uncomfortable? ”

"No, no." Su Yong sniffed a few more times and said

"Actually, when I came in the afternoon, I noticed that it seemed to be much cleaner?"

Guan Shuang pursed his lips and asked suspiciously

"What do you mean by that?"

Su Yong looked around the warehouse again and said

"Wasn't I the first to rush in last night, it seems that I saw some dust in the warehouse, but this afternoon and this time I came in but there was no more, if it weren't for what Yang'er said just now that digging three feet in the ground reminded me of the scene of smoke and dust, I still can't remember it."

Zhang Kexin lit a cigarette and responded to Su Yong nonchalantly

"Maybe there's some dust on some of the materials, and now they've been taken out, so..."

"It's impossible." Guo Hongyi said very simply, we looked at Guo Hongyi with curious eyes, he pointed to his nose and continued

"I have rhinitis, and if there is ash in the air, my nose will be very uncomfortable, but yesterday I didn't feel the slightest discomfort, so there must have been no ash when I came in yesterday."

I heard Guo Hongyi say this, "haha" laughed and mocked

"How many problems do people have when they get old?"

Before Guo Hongyi could attack, Guan Shuang knocked on his chin and muttered

"It's... It's very strange, what will Su Yong see? ”

Zhang Kexin sighed a little helplessly, put his hand on Guan Shuang's shoulder and said

"I guess Brother Yong is simply wrong, right?" As he spoke, he glanced at Su Yong with a smile.

Zhang Kexin's tone was full of comfort, in his opinion, Guan Shuang should be eager to prove himself because he wrongly blamed Li Mengqiao just now, so he was also very concerned about some irrelevant things.

But unexpectedly, Su Yong was extremely confident this time and retorted categorically

"Impossible, because I felt very strange last night, I saw the ashes, but in a blink of an eye, they disappeared quickly, and I wanted to say it at the time, but I never had a chance, and then I forgot about it."

Although Su Yong usually seems a little unreliable, he has an advantage, he never says things that he is not sure about, and he does not like to lie, and it is impossible to deceive us in this situation.

Seeing that Su Yong was so confident, we were also a little hesitant, and Guo Hongyi also touched his nose a little unconfidently and said

"That's weird, I'm not lying, my rhinitis is quite serious, if there is any dust, I must feel very uncomfortable, didn't you find that when Yang'er and Kexin smoked, I hid far away?"

When Zhang Kexin heard this, he looked at the cigarette in his hand embarrassedly, a little overwhelmed, I shook my hand and signaled him to hurry up and throw away the cigarette, Zhang Kexin took a puff with some reluctance, and hurriedly threw the cigarette to the ground, and stepped on it with a few feet.

Guo Hongyi became a little embarrassed when he saw the reaction of the two of us, and hurriedly defended

"That's not what I meant, I just mean the nose."

"That's weird." Su Yong touched his chin as he learned to be shuang, and muttered to himself with a puzzled face.

Guan Shuang saw that Su Yong was so sure, and asked me

"Yang'er, I can't think of anything that looks like ash, but it's not, you are a scholar, do you have any ideas?"

I feel that Guan Shuang is a little too sensitive now, and he is holding on to such details, but he has just experienced a mistake, and if I refute him now, it will definitely hurt his self-esteem, I replied uncertainly

"Fog?"

Su Yong thought I was teasing him again, and complained a little angrily

"What are you kidding, how can there be fog here??"

"Heck, I mean, for example, the water vapor in the air liquefies into a large number of small water droplets, which is commonly known as fog, but it can be mistaken for dust, and it is unlikely, unless..."

Guan Shuang stared at the vent and analyzed with some suspicion

"This vent is straight to the outside, so the temperature of this warehouse and the outside is almost the same, how can the water vapor in the warehouse liquefy into small droplets when it is so cold?"

I shook my head helplessly, I didn't expect Guan Shuang, who had such a wide range of knowledge, to know nothing about it, and explained with a wry smile

"Liquefaction does not necessarily have to reduce the temperature in the room, if this temperature comes in the warehouse below zero, the temperature of the person is about 36 degrees, then the water vapor around the person will liquefy into water droplets when cold, just like you who wear glasses, don't you often cover your glasses with a layer of fog in winter? Actually, that's liquefaction. ”

Guo Hongyi clapped his hands after hearing this, and shouted suddenly

"There was fog here before Brother Yong came in, so that means there might be a person in this room?"

Zhang Kexin took a step forward and said excitedly

"That is, someone somehow got into the warehouse and hid in a corner, and we couldn't see him outside."

"Then a few seconds after the lights went out, he took the gift box, and after the boss opened the door to the warehouse, we rushed in, and he ran out in the dark?" Su Yong also happily joined the discussion.

The more they talked, the more excited they became, and even Guan Shuang said

"That's right! The boss said that no one passed by the bar until the sound of glass breaking, but if the prisoner took out the gift box after we entered the warehouse, and there was no one at the bar at that time, she could have passed by the bar and transported the gift box upstairs or outside, so the most suspicious thing is..."

"Wang Yiran!" The five of them said in unison, ecstatic.

When I heard them come to this conclusion, my jaw almost fell off in surprise, and I hurriedly stopped

"Hey, wait, wait..."

But they didn't listen to me at all, and they still talked about it selflessly

"Moreover, when she was drinking honey tea, she also offered to give us teacups, which may have been done at that time."

"Wait a minute, wait a minute..."

"Absolutely, yes, I guess she must have sent the gift box outside the hotel first, and when she came back, it happened that the boss ran out, and the two ran into each other, and there was no way to say that she was going out to buy snacks."

Listening to them get more and more serious, I yelled

"That's it! Wait! ”

This roar pulled their souls back, and they all looked at me blankly, Zhang Kexin instructed blankly

"Yang'er, you're not well yet, don't be so excited."

After shouting so loudly just now, I also gasped for breath and said

"It's because your reasoning is so outrageous that I'm so excited."

Su Yong felt that it was very unpleasant for me to speak like this, and reprimanded

"How outrageous is our reasoning? It's completely logical, and didn't you say that it was because someone was in the warehouse that the water droplets were liquefied? ”

I threw up my hands helplessly, surrendered, and persuaded them in as gentle a tone as I could

"Big brothers, even if you really don't study science in high school, but these are junior high school courses, okay, when you all eat, but please recall, you have seen anyone who entered the room in winter, full of fairy energy! Didn't I just say that if it is a natural liquefaction phenomenon, how can there be so many water droplets that people mistake them for ash? ”

Su Yong still refused to give up and argued

"Okay, we don't care if the liquid is liquefied or not, then our reasoning is completely possible, the prisoner should be Wang Yiran."

"Impossible, impossible." I shook my head again and again, looked at Guo Hongyi and said

"Don't forget, there is only one key, it has always been with the boss, and the door was checked by Brother Guo, there is nothing unusual, how can someone enter in advance?"

My words were like pouring cold water on them, and the five of them lost their previous excitement and became depressed, and Su Yong still muttered incomprehensibly

"And what exactly am I seeing?"

Seeing that he was still struggling with that kind of thing that had nothing to do with the case at this moment, I already rolled my eyes angrily, and said with my hands spread out almost pleadingly

"Brother Yong, maybe all you see is the moonlight, besides, even if it's really foggy or gray, it may not be related to the case, why bother with this?"

In the past, Su Yong should not have said anything, but this time he insisted extraordinarily and retorted again and again

"I'm not mistaken, it can't be moonlight, now that I think about it, like you just said, it's like a fairy."

I was almost so angry that Su Yong was about to scold and asked

"Brother, are you here to talk to me? Do you want to say that Sun Wukong came to steal the gift box? ”

Su Yong also realized that what he expressed was not very accurate, shook his head, and re-explained

"Well, I didn't mean that, I meant that there was a cloud of smoke that looked like the Heavenly Palace in the Journey to the West TV series."

I really didn't want to argue with Su Yong anymore, so I waved my hand and twisted my head to the side, not wanting to say anything more, Su Yong was also so angry that he crossed his arms and stopped talking nonsense.

Seeing that the atmosphere was a little embarrassing, Guo Hongyi hurriedly came out to play a round and said

"Yang'er, don't be like this, don't forget, Brother Yong is our lucky general, like the last time at S Normal University, the secret of cracking Xin Yi's death and discovering that Jiang Junqian is a girl was not inadvertently reminded by Brother Yong?"

Guan Shuang also persuaded Su Yong and said

"Yang'er is anxious because she has a cold now, that's why she is so impatient, it's not that she doesn't believe you." Then he said to me

"Brother Guo is right, Brother Yong can always give us some unexpected hints, let's say it's metaphysics, Brother Yong has this kind of talent, but this is a fact, and Brother Yong is not wrong, anything strange at the scene of the crime can't be ignored."

In fact, Su Yong and I were not too angry, after all, brothers, Guo Hongyi and Guan Shuang said this, give me and Su Yong a step, and the attitudes of both sides have eased a lot, Zhang Kexin struck while the iron was hot, and asked in a haha

"Oh, Yang'er, don't worry about the case, I'm really a little curious, how did the immortal energy in the Heavenly Palace in Journey to the West come from?"

I glanced at him, and was about to descend the steps, explaining

"That's dry ice, which is solid carbon dioxide."

Su Yong also glanced at me, and continued my words with a very good face

"I seem to have seen it on the Internet, it's called sublimation, right? Or what? ”

I nodded

"That's right, dry ice is solid carbon dioxide, which is very easy to sublimate in the air and become carbon dioxide gas, but carbon dioxide is invisible, and the white fog we see is that dry ice sublimation absorbs a lot of heat in the air, causing the temperature of the surrounding air to drop, and the water molecules in the air are condensed into small water droplets."

Guan Shuang saw that Su Yong's attitude and I had eased a bit, and continued

"Ah, that means that only dry ice can form a fog like smoke? According to what you mean, the transformation of gas into liquid is liquefaction, and the direct transformation of solid into gas is called sublimation, so what is the name of solid turning into liquid? ”

I heard that Guan Shuang had nothing to say here, and he wanted me to show off my knowledge, so that I could be satisfied in my heart to dissipate my anger, I rolled my eyes and said

"It's not what I said, that's what physics says, a solid becomes a liquid called melting... Wait a minute! ”

I jerked my head up, looked at Guan Shuang in disbelief, and muttered to myself

"Only with dry ice can you form a fog like smoke? Is there dry ice here? But what is dry ice for? Solids into gases? Solids into gases? Thinking about it, I unconsciously bit my nails, Su Yong and the others saw me like this, and all of them stopped talking with tacit understanding, and they could even say that they held their breath, looked at me intently, waiting for my answer.

Why do you think of something when you hear these words? What is it? What is it? After thinking about it for about 5 minutes, I slowly lowered my fingers, and Guo Hongyi saw this and hurriedly asked

"How? Got that thought? What is the answer? What the hell is going on? ”

Su Yong also asked

"Did my discovery remind you again? I'm doing it again, right? ”

Looking at their emotional looks, I said with a smile
