The next day, at seven o'clock in the morning, in the hallway of the school building.

Pang Zhenjun walked slowly through the corridor, but a few traces of doubt flashed on his face. It stands to reason that this is usually the time when there are the most students, but now there is not a single student in the long corridor, which makes Pang Zhenjun instinctively feel that something is wrong.

What made him feel even more strange was that every classroom he walked through had the curtains drawn, so he couldn't see the inside clearly.

"It's kind of weird." Pang Zhenjun muttered.

When Pang Zhenjun came to the third (1) class of high school and saw everything in front of him, he was stunned and stunned.

At seven o'clock in the morning on a hot summer day, there was a thick layer of frost on the doors and windows of the third (1) class of high school.

On the frosty window, a love heart is very eye-catching. Through this love, the classroom can be faintly seen to be filled with smoke.

A figure hangs on an electric fan, swaying from side to side. After more than ten seconds, the figure struggled and fell to the ground with a "bang" after a while.

Then the figure got up, swayed and walked towards Pang Zhenjun, and slowly pushed open the window......

"Hell! Help me! Pang Zhenjun fell to the ground in fright, shouting frantically.

The frosty window was pushed open, and in the smoke, Jiang Tian took off the oxygen mask on his face, looked at Pang Zhenjun on the ground, and sighed heavily.

Almost at the same time, the door of the next classroom opened, and the students and teachers poured out of it immediately filled the hallway, making the originally empty hallway suddenly bustling.

Pang Zhenjun was a little overwhelmed, and before he could react, he was handcuffed by Shen Sen.

Jiang Tian came out of the classroom and took off his coat and small oxygen supply equipment.

"I almost froze to death, it's like a refrigerator, no, it can be called an ice room." Jiang Tian shuddered, gave Pang Zhenjun a thumbs up, his voice was a little bitter, and said, "Old Pang, your killing method is really artistic. ”

"What do you mean?" Pang Zhenjun calmed down a bit, "Jiang Tian, what crazy are you talking about?" ”

At this time, Xu Ang took a large incubator, squeezed through the crowd, and came to Pang Zhenjun.

"Lao Pang, how confident are you, and you still put the killing tool in your bedroom, are you really stupid to be a policeman?" Jiang Tian sighed, "We also found some hemp rope in your bedroom, it should be left after hanging Qi Lan." ”

"Not true." Pang Zhenjun chuckled lightly and said lightly, "I use the rope to tie things, and I use the incubator as a storage box." ”

"And what about this coat?" Jiang Tian slammed the coat he was holding on Pang Zhenjun, "The police found some rubber chips in the cracks of Qi Lan's nails, and after identification, they were on this coat." And this coat was brought over by me to Ni Gang from your closet. ”

"When did you do these things?" Pang Zhenjun was a little surprised.

"Then I'll tell you about it. Last night, I figured out some things, the smoke in the classroom, Chen Jiao's suffocation, Yang Xue's coma, Brother Xu's low temperature, these phenomena are connected, plus the laboratory accident, I can only think of one key connection point, that is, dry ice! ”

"At noon the day before yesterday, there was an accident in the laboratory, and a teacher passed out and fell unconscious after entering the laboratory. Fortunately, he was found in time and was sent to the hospital for rescue, and later woke up and was fine. After investigation, the carbon dioxide concentration in the laboratory reached 3.5%, which was significantly higher than the normal value, and the door of the dry ice freezer in the storage room next door was not closed tightly, and a leak occurred, and the sublimation of the dry ice inside produced a large amount of carbon dioxide, which overflowed from the freezer to the storage room, and then passed into the laboratory through the connecting door. The doors of the laboratory are not always open, so the carbon dioxide accumulates more and more. ”

"What's wrong with that?" Pang Zhenjun looked at the heart shape on the glass and asked softly.

"The door of the dry ice freezer is not closed, either because the administrator accidentally forgot to close it, or because someone stole the dry ice and forgot to close it." Jiang Tian also looked at the smoky classroom, "Because there is surveillance outside the laboratory, thieves can't transport dry ice out from the main entrance, so you first put the incubator on the unmonitored grass behind the laboratory, then open the window from the laboratory, jump onto the grass, take the incubator and return to the laboratory from the window, and then enter the storage room through the door that connects the laboratory and the storage room, and put the stolen dry ice into the incubator." After installing it, put the incubator back on the grass outside, and finally get out of the laboratory and go around to the back of the building to get the incubator. ”

"Almost, Jiang Tian, your imagination is good." Pang Zhenjun said.

"I think, you made an appointment with Qi Lan to meet in the classroom, but you came to the classroom early and threw some dry ice into the classroom, Qi Lan should have fainted due to suffocation as soon as she entered the classroom. After that, you go in, hang Qi Lan on an electric fan, and finally put the rest of the dry ice indoors. The sublimation of dry ice absorbs a lot of heat, causing the temperature of the classroom to become very low, and such a so-called suicide scene is faked. In fact, you have done a good job of hanging her directly on the electric fan instead of hanging it up after death, so that the police once thought that she was really committing suicide. However, the abnormal temperature of the corpse made the police suspicious, and that surveillance showed that Qi Lan died of murder. The smoky classroom that Chen Jiao and Yang Xue saw was actually the condensation of water vapor in the air when the classroom temperature was too cold, just like when we usually open the refrigerator door. ”

"Why do you suspect me?" Pang Zhenjun looked at Jiang Tian and asked calmly.

"Isn't the love on the glass obvious enough? I thought that the classroom might have been frozen, so I took some dry ice to the classroom last night and did an experiment, and when the temperature in the classroom became very low again, the windows froze, and the 'gone' love reappeared. Jiang Tian looked at the window, "Seeing this, I suspect that the murderer is you or Shang Zhong, but although Shang Zhong looks crazy, he is too timid, but he is the black-bellied old Pang, who is even more suspicious." ”

Jiang Tian smiled bitterly, his voice was a little sour, "But I didn't expect that just after investigating you, I found so much evidence, it's really ......"

"Actually, you should be happy, I left so much evidence, didn't it just so that you could catch me earlier!" Pang Zhenjun laughed a few times, "It's just that your speed is much faster than I thought." ”

"Pang Zhenjun, I want to ask you, why did you kill Qi Lan, and why did you arrange it to commit suicide? With your IQ, you wouldn't have thought about surveillance, would you? And those evidences, how could you be stupid enough to put them in your dorm? ”

"One of the most important questions is, why freeze this classroom with dry ice? What's the point of doing that? ”

Jiang Tian grabbed Pang Zhenjun's neckline and stared into his eyes and asked.

"Surveillance, evidence, and the love I painted on the window, Jiang Tian, don't you really think of it?" Pang Zhenjun had a smile on the corner of his mouth.

"Could it be that you were planning to turn yourself in after killing Qi Lan?"

"Huh." Pang Zhenjun sneered a few times, "You still haven't figured out why Qi Lan died laughing." ”

"For ...... Why? ”

"Because I didn't kill Qi Lan at all, haha, Jiang Tian, but I'm willing to accept the punishment of the law!"

Everyone present did not understand the meaning of Pang Zhenjun's words.

"Ice is the beauty with the breath of death, and when it kills everything with its coldness, it is also freezing all the beauty and eternity of everything!" Pang Zhenjun's eyes flashed with excitement, "Our love is to experience the baptism of perversion!" Perverted love is the craziest, the most thorough, the purest possessive! If you can't get it, you're willing to die, whether it's the other party or yourself! ”

"Qi Lan, how did she die?" Jiang Tian's voice trembled a little.

"So we freeze our past, we freeze our love, we freeze ourselves forever in the past! I really love her, and she really loves me, so we are always ready to kill each other, hahaha! ”

Pang Zhenjun laughed and cried wildly.

Until he was taken away by the police, Pang Zhenjun did not answer Jiang Tian's question.

But Jiang Tian didn't say anything, because he had already thought of that terrible answer.

……

She gave him a wayward love and took her life as a dowry.

He gave her a death ice chamber in return, hiding his guilt for her.

Is this the philosophy of perverts?

Or is it the embodiment of shameless possessiveness?
