Chapter 460

Yu Bing replied fearlessly.

"Oh, who told you that?"

"Yue min."

"You fart. How can Yue min tell you to do that?"

Yue Lushan next to him was so angry that he almost jumped up. He used to be a boy who really came from the first place. Now when he thought about it, he really thought too much.

"Look, I'll tell you the truth, you have to believe it."

Yu Bing shrugged his shoulders. In fact, he didn't want to play the play himself, but if he didn't come, Yue Lushan would let people observe himself secretly, which would also affect an and Hongxue.

Anyway, they are all harassed. It's better to send them to Yue Lushan to harass them. Anyway, they can't find anything.

"Hum, don't quibble, even the most perfect crime will leave traces."

Like a threat to the soldiers, Yue Lushan glared at them fiercely.

At this time, Pang Luo and the police chief came in. As soon as they went to the door of the interrogation room, Yue min came in from the outside.

"Boss Yue, don't say anything more. Just look at the monitor. There are three monitors in front of the art room." Said the interrogating officer.

At first glance, he seemed to have no problem, but he found the problem.

I know only two of the three monitors, so where is the other monitor.

The police chief walked in front of the interrogating officer and looked at the record on A4 paper.

"Is surveillance coming?"

The chief of the police station turned over his confession, and there was no clue on it, let alone any evidence to identify Yu Bing's crime, which also reassured him a lot.

"We've got the surveillance video for the first time, but the three monitors at the entrance of the art room haven't captured anything."

The police officer brought Yue Lushan's tablet, which can view all the surveillance videos freely.

The police chief wiped his hand, took the tablet in the officer's hand and turned to the surveillance screen in the gallery of the art room.

A few people all came over, staring at the picture above.

During the monitoring, several college students first stood in the corridor and smoked for a while, then passed by a student, who was Hu Jinke.

After leaving school in the afternoon, Yu Bing finally appeared in the monitoring screen.

It happened that two students who entered the art room passed by with a stack of paper, and Yu Bing wandered into the corridor behind.

Hu Jinke walked in front of the two people entering the art room, and Yu Bing quickened his pace to catch up.

About to contact, Yu Bing pushed Hu Jinke away, and he staggered.

"Ha ha, if you don't leave such a big gap, you have to push others. Boss Pang's nephew really deserves the reputation."

Yue Lushan, standing on one side, laughed.

"Where, boss Yue's fire-fighting measures are also good. There is no fire extinguisher in the corridor."

Yu Bing is not polite to the color.

Yue Lushan snorted coldly and continued to look at the monitor.

Hu Jinke was staggered and immediately stabilized, but Yu Bing, who came over later, pushed Hu Jinke onto two students holding art paper.

Hu Jinke also has a good temper. Instead of causing any trouble to Yu Bing, he apologizes to the two students.

The pictures after that have nothing to do with the art room.

The police chief closed the tablet and put it back on the table.

"People, do you think it's artificial?"

After that, the police officer turned on the monitor again, transferred to Yu Bing's picture, and slowed down Yu Bing's movements.

"If it's artificial, then we can only lock the people who appear on the monitoring."

After hearing what the police officer said, Yue Lushan nodded with deep approval.

In his opinion, Yu Bing is the most suspect of these five people. No, it should be Yu Bing who did it, but the boy didn't admit it.

Take out the phone, Yue Lushan called the school management office.

After waiting for a while, the people in the surveillance came to the interrogation room of the police station.

When entering the door, Hu Jingke secretly glanced at Yu Bing, then quietly raised his glasses.

Yue Lushan, standing next to the chief of the police station, was staring at the change of people's looks.

After Hu Jingke came in, he stood beside pangluo, not with other people.

"Hu Jingke, you are also one of the suspects. Please stand over there."

The police chief held the table and took a complicated look at Hu Jingke, pointing to the people standing next to the soldiers.

"Well, I'm a college student with excellent character and learning, and I've become a suspect."

He mumbled, but Hu Jingke walked into the crowd.

"Everyone must have heard about the fire in the art room of Mr. Yue's school. It's the same thing that you were called here."

The interrogating officer played the video again on the big screen.

"I want to know why Yu Bing is pushing Hu Jinke?"

"Do I need a reason to push people? He's in my way. That's the reason."

Yu Bing stood up and said he was wronged.

"If you don't leave such a big gap, do you have to go my way?"

Hearing Yu Bing's words, Hu Jingke seemed to retort with some dissatisfaction.

"Well, let's not talk about personal grievances. I want to hear your opinions."

The police chief clapped his hands and looked majestically at the people present.

At this time, Yue min, who was standing next to him in silence, came over and walked to the video.

Nodded to the police chief and the officer.

"There is no chemical spontaneous combustion in the art room at all, so the spontaneous combustion is eliminated. In addition, the air outside is humid in spring and March, so the fire can not be caused by the weather."

"Excluding these two reasons, then it can only be man-made. How to set fire without entering the art room is also very simple."

After a pause, Yue min looks at Yu Bing sitting on the interrogation chair.

"Of course, it's metal elements with very low melting point, such as metal cesium. Many pigments in the art room volatilize, making the room temperature not very low, so there's only one condition for flammable elements to spontaneously ignite."

Yue min pointed to the sky outside the iron window.

"Air and water. As I said just now, the air is humid in March of spring, so this condition has been established. Now this theory has been established."

"The conclusion is that after the outdoor humid air enters the art room, it will not make the art room cool down immediately, on the contrary, it will cause the metal cesium which has stored the heat energy in advance to explode."

Yue min's eyes are still on Yu Bing after his speech. Although his foreign language is not very good, his talent in chemistry is absolutely as good as that in business.
