Leng Feng didn't notice that when he was surveying the scene, in an unexpected corner, there was a look of resentment, as if he wanted to kill him.

"That's not right. If the fire started burning from soot, how could there be an explosion? If the explosion was to ignite the soot and burn it, how could it be like this? The shock wave of the explosive is enough to make the soot bricks fly everywhere.

How come the smoke is so concentrated?" Leng Feng quickly discovered the clue.

Leng Feng turned around and asked the policeman next to him: "Who was the officer on duty closest to the evidence room that night?"

The young policeman said evasively: "Yes...it's the chief." Wang Fugui glared at him, as if to warn the young policeman not to talk nonsense.

Leng Feng snorted: "Director, all the witnesses and physical evidence now point to you being a thief, so if you have any clues, you'd better tell me quickly, otherwise, I won't be able to save you."

Wang Fugui looked at the policemen around him, weighed it up, and said: "I asked you to investigate this case, but who asked you to investigate me! If I did it, can I get you to investigate the case?!"

Leng Feng was stunned for a moment, and then he looked at Wang Fugui with an approving look as if he suddenly understood, and said: "Director, since you asked me to investigate, I shouldn't have any reservations. Only if I know all the details, can I

Catch the daring guy who dared to blow up the police station building."

Wang Fugui put his hands behind his back: "I was indeed on duty that day. These things are of great value. Just in case, I asked a team of men to be on duty on the first floor, but!" Wang Fugui said sternly: "

Although I am the only one who has the key, I definitely did not open the door to the evidence room!"

Leng Feng knew in his heart that there was no need for Wang Fugui to guard himself because the whole situation was known to everyone. Since even the patrol police knew about it, it was impossible for the higher-ups not to know about it. The reason why they did not come to take a share of the pie was probably very complicated, and Leng Feng

The task to be performed is to find those Japanese spies, but there is no way to start. Since there are clues about the Japanese spies here, why not try your luck?

Leng Feng saw traces of a pool of black stuff on the ground, so he put on his gloves and rubbed the black stuff off, revealing something white and metallic.

"Sodium?" Leng Feng looked at the remaining sodium and couldn't help frowning. This sodium is not a commonly used metal and its chemical composition is unstable. There must be something wrong.

"Hey!" The sodium that had been wiped off by Leng Feng was actually on fire. "On fire?!" Wang Fugui pointed to the flames on the ground.

Leng Feng wondered: "Sodium metal is an extremely reactive metal and is usually soaked in kerosene."

"Is it because the weather is dry? It shouldn't be. It was raining that night!" Wang Fugui muttered. The fire that day was so strange. It was raining heavily and it caught fire immediately. It was difficult to put it out, so it must have been exploded by someone else.

of.

Leng Feng turned around and asked Wang Fugui: "Who was the first to discover the fire?"

Wang Fugui was stunned for a moment: "I, I, I don't know, I ran over when I heard the explosion."

Leng Feng touched his chin. If the box containing the tobacco contained sodium metal stored in kerosene, once the tobacco was stolen and stored improperly, the sodium metal would be exposed and return to heat when exposed to air. In addition, it was raining and the air was humid.

It may even leak, and the metallic sodium will explode directly when it comes into contact with water.

Leng Feng closed his eyes and reconstructed what might have happened that day. The police did not know that there was a mechanism in the soot, so they placed the box of soot randomly. When all the kerosene in the mezzanine or the bottle flowed out, the metallic sodium was exposed to the air.

, it starts to heat up, and when it reaches a certain temperature, it ignites the kerosene, then... wait, no, once it catches fire, even if it rains, it will not cause an explosion.

Leng Feng felt that he had left something behind, but where exactly was it that he had not discovered? Then he looked at the house and found that although not much had been destroyed, important clues had been destroyed.

"How long has this fire been on?" Leng Feng asked Wang Fugui, and Wang Fugui immediately replied: "Fifty-two minutes!"

Why did Wang Fugui know so well? Because there was smoke worth several large yellow croakers in it. Every second it was on fire, he was frightened and his heart was bleeding. How could he not remember clearly!

Leng Feng raised his head and thought. If there was an explosion first and then he went to put out the fire, it means two things. First, there was no open flame before the explosion. At least the open flame was not so big that someone could see it from the window. Second, it means

The raw material that can cause an explosion is definitely not just a bit of metallic sodium, there must be something else! Even if there is some sodium in the interlayer, it is only enough to burn the box, but it will not cause energy that can burn down the whole house.

Leng Feng racked his brains and couldn't figure out what he had overlooked. To be precise, he couldn't guess.

Now that the clues here are broken, we can only find another way. Leng Feng stood up, patted the dirt on his gloves, and said: "Until the case is investigated clearly, no one can enter or leave the evidence room without my order." Then he looked at Wang Fugui.

: "Can I take a seat in the bureau?"

Wang Fugui cleared his throat: "Ahem, um, since I have given you the full power, then you can do whatever you want. I won't ask or interfere. Just let it be Deputy Director Yi Leng!"

Back in the office, Wang Fugui looked at Leng Feng nervously. He didn't know what conclusion Leng Feng would draw, and he was afraid that he would lose his job.

Leng Feng sat on the sofa for a long time without saying a word, which made Wang Fugui fidget a little. Finally, Leng Feng spoke: "Director Wang, as far as you know, this box of cigarettes is on the market.

Is it considered a large quantity?”

Wang Fugui hurriedly said: "No, it doesn't matter. This little bit of tobacco is sold out in one night in a slightly larger opium shop on the market. It's not that much."

Leng Feng nodded: "If you were a tobacco seller and the tobacco was confiscated, would you want to destroy the tobacco at the risk of alerting the police station?"

Wang Fugui was stunned for a moment, and replied dumbly: "Of course... no, let alone a suitcase of tobacco, even a few large wooden boxes, you have to hold your nose to identify it. If you have the background, the sales channels are not able to

If we are lucky enough to find out who we are, someone will come from above to take away the people and goods... So..." Wang Fugui muttered to himself, then patted his head fiercely: "The box.

Besides smoke and dust, there are other things inside! What they want to destroy is something else!"

Leng Feng happily clapped his hands twice: "Director Wang is really quick in thinking and can understand everything at once. Then, Director Wang, you should know why I'm here, right?"

Wang Fugui completely knelt down. Leng Feng could see his hesitation and unwillingness, so he tried to encourage himself to be smarter.

"Report, bureau chief, Cheng Xiaoman is here," a police officer reported. Wang Fugui looked at Leng Feng and said, "See you there, didn't you see me discussing official business with Deputy Director Leng?! Get out!"

Leng Feng touched his chin and said, "Wait! Let him wait for me at the door of the police station."

The police officer saluted: "Yes" and then left.

Wang Fugui secretly looked at Leng Feng, who was leaning on the sofa: "A drop of kindness is repaid by a spring. What's more, Cheng Yiyuan is more than a drop of kindness to me. His orphan, if I don't take care of him, it will be unreasonable."

, can’t even be justified.”

Wang Fugui immediately said: "How do I know where Cheng Xiaoman is coming to find you? But he is also the son of an old friend. Marshal Cheng also met me a few times before, so I asked him to lead a patrol officer at the police station first.

Go ahead, at least you’ll have something to eat.”

Leng Feng snorted twice: "So, Director Wang is more affectionate and kind than me. In comparison, I, a person who has been favored by others, am unkind and unkind?"

Things are not that simple. A skinny camel is bigger than a horse. Since Cheng Yiyuan is a tycoon, he must have expected that he would die and lose his family's wealth, leaving no way for his son? Leng Feng didn't believe it, so this Cheng Xiaoman came
