Zhou Lingwu recounted some of his views on the scene to Director Chu while calling Zhan Lu in his heart, but the strange thing is that no matter how Zhou Lingwu summoned, he still couldn't hear Zhan Lu's reply, which couldn't help but make Zhou Lingwu feel a little panicked, Zhan Lu is his current strongest combat power, not to mention, he is still equivalent to his "own flesh and blood" general companion, if he loses this fierce general Zhou Lingwu will regret his decision to let Zhan Lu go here to investigate for the rest of his life.

"Young Master, what's wrong?" Seeing that Zhou Lingwu had scruples in his heart, the Seven Bear Elder asked Zhou Lingwu regardless of the existence of Director Chu beside him.

"It's okay, Elder Qixiong, you continue to take Yang Zhongshan to see if there are any powerful clues." Zhou Lingwu looked at the seven male elders with concern in his eyes, shook his head with satisfaction and said.

The speaker is unintentional, but the listener is intentional. When Director Chu heard that the old man in front of him who looked highly respected was actually commensurate with Young Master Zhou Lingwu, he couldn't help but muttered in his heart, could it be that this Zhou Lingwu is still the young master of some big family? If that's the case, I'll have to talk about it, and I won't need him in my career?

Zhou Lingwu is not in the mood to care about what Director Chu is thinking now, now he is full of worries about Zhan Lu, but Zhou Lingwu is worthy of being a person who has been to the execution ground, even if he is in a hurry, he can calmly use two things. At present, there are many suspicious places in Li Yu's house. The strange black smoke stains in the bedroom, according to reason, if the source of the explosion is the kitchen, then the smoke stains in the bedroom should be irregular, but the smoke stains in front of him are scattered from the bed that has burned to the point that only the broken skeleton remains, and the smoke stains are very deep.

Zhou Lingwu put his cigarette-stained fingers in front of his nose and sniffed gently, a pungent sour smell came to his nose, and this smell carried a unique humidity, which made people feel very uncomfortable. After feeling the smell carefully, Zhou Lingwu turned his head and said categorically to Director Chu: "This is realgar, I think this is a murder case that has been planned for a long time. ”

"I know that, but you have to have a definite reason, right?" Director Chu couldn't help but roll his eyes at what Zhou Lingwu said, who could not see that this was a murder, not to mention the suddenness of the explosion, that is, the explosion occurred at almost the same time between Lao Wang and Lao Li, and this incident itself proves that this is not an accident.

Zhou Lingwu smiled when he heard this, he realized that what he said was too abrupt, and then he reached out and wiped a little cigarette stain on the wall next to him, handed it to Director Chu, and motioned for him to smell it.

Director Chu looked at Zhou Lingwu suspiciously, and slowly leaned his nose over, he thought in his heart, I don't think this kid will dare to do anything to me under the nose of so many policemen, then I will smell it.

"Poof! Oops! What a taste this is, catch up with the smell of stinky sour feet! Director Chu shrugged his nose, a pungent breath went all the way down his nostrils to his brain, he hurriedly took back the head that popped out, and kept fanning his hands in front of his nose, trying to blow the smell away.

Zhou Lingwu looked at Director Chu Guan Er, who was so emotional, and then explained: "This is the smell of realgar, and it was nothing else that detonated Li Yu's family, it was this realgar explosive!" ”

"Oh? How do you say that? Many of the police officers who were busy heard that the little detective who was in the flower shop at that time had an idea again, and everyone couldn't help but put down the busy work at hand and listened, after all, it was a comfortable thing to listen to a detective deduce the case.

Zhou Lingwu opened his mouth when he heard this: "As we all know, realgar is a very useful item whether it is used for medicine or to ward off evil spirits, but few people know that realgar can also be used as one of the raw materials for making explosives. ”

"Little one, how do you know so much?" A police officer leaning against a door frame asked.

"I just read a lot of books." After answering the policeman's words, Zhou Lingwu continued to explain: "Realgar itself is not explosive, but when it is mixed with potassium nitrate and charcoal in a certain proportion, it will turn into a powerful miniature explosive. The principle of operation of this explosive is very simple, potassium nitrate is chemically reacted to release oxygen, and enough oxygen can cause charcoal and realgar to burn, producing large amounts of heat and nitrogen, as well as carbon dioxide and other gases in an instant. Due to the rapid expansion of the volume in a short period of time, the pressure also increases dramatically as the volume increases! An explosion ensued. This explosive has extremely poor stability and can be detonated at room temperature. ”

Everyone nodded suddenly when they heard this, and everyone rubbed a little cigarette stain from the wall next to them and put it on their noses to sniff the smell of realgar carefully, in case realgar appeared in the house in the future, and they didn't have time to prevent it.

Seeing this, Zhou Lingwu continued to explain: "But this is not the most deadly, if it is just the explosion of realgar explosives, the fire and smoke caused by it are not enough to kill, but the most lethal is that realgar is inhaled into the human body beyond a certain amount, which will cause kidney failure, and what kind of results kidney failure will bring to human beings, I think everyone knows better than me." ”

The police officers who had originally smelled the smell of realgar couldn't help but be stunned when they heard this, and then immediately exhaled heavily, wanting to spit out the inhaled realgar.

"Don't worry, you're inhaling less than one-thousandth of the norm." Zhou Lingwu said, "But Officer Li's wife is obviously not as lucky as you, after the explosion, the remnants of the realgar that has not had time to burn and other substances have been volatilized, and perfectly hidden in the thick black smoke emitted by the flames, I estimate that the cause of the victim's death is likely to be dyspnea caused by kidney failure, and finally suffocated to death." ”

Zhou Lingwu's guess was not wrong, the results of the forensic examination had just been released, and the report had just been sent to Director Chu. Director Chu carefully flipped through the test sheets, and he found that the cause of the victim's death was exactly the same as Zhou Lingwu's guess, and it was not the same. This couldn't help but deepen his desire to take Zhou Lingwu under his command.

Director Chu knocked on the side and said, "Boy, you are really a god!" The test sheet is exactly what you said, as if you wrote the test sheet! What are you doing now, and are you interested in being a police officer? ”

"Director Chu, we'll talk about this matter later, I want to see the test reports of Officer Wang and his family." Zhou Lingwu avoided Director Chu's questioning and led the topic elsewhere.

Director Chu was embarrassed to ask again when he saw that he had eaten a closed door, so he had to obey Zhou Lingwu's will and handed over Lao Wang's test sheet to Zhou Lingwu's hands.

Zhou Lingwu carefully investigated the laboratory test in his hand, and he found that Lao Wang and his family and Li Yudi's wife died almost the same cause, which proves that the murderer is indeed the same person, but judging by the time of death, the time interval between the two explosions is less than a minute, which shows that the murderer wants to kill them all, leaving no one of the two people on the murderer's "death list" to escape. But if it's the same person who committed the crime, how can he ensure that it is almost simultaneously completed?

"Young master, there's news from Zhan Lu." The Seven Heroes quietly approached Zhou Lingwu and said.

"What? Why can't I get in touch? Zhou Lingwu said suspiciously, since he arrived at Li Yu's house, he has been transmitting to Zhan Lu all the time, but there is no news from Zhan Lu's side, he still thinks that something happened to Zhan Lu's side, but now he actually heard that the seventh male elder got the news of Zhan Lu, how can this not make Zhou Lingwu suspicious?

"Zhan Lu said that he couldn't contact you over there, and I don't know why. He said that he was in the house surnamed Wang, and he checked some favorable clues! The Seven Heroes said.

Zhou Lingwu wondered when he heard this, why couldn't he contact him, could it be that something was wrong on his side? The Seven Heroes were able to receive the news over there, but my side couldn't, this is not the first time, I received the news of Zhan Lu in the tunnel before, what is the reason for this.

But now Zhou Lingwu obviously doesn't have time to pay attention to this matter, the death of Li Yu's family and the death of the police officer surnamed Wang are clearly not an accident, this is obviously a long-planned murder incident, and the cases in Li Yu's house are all clear that the murderer should have started to prepare at least three months ago, and he can master the ratio of realgar explosives so skillfully and calculate the time of the explosion is almost exactly the same as the explosion of the police officer surnamed Wang's house!

This can show that at least the one who wanted to kill Li Yu and the police officer surnamed Wang was not the murderer of the Huafang case this time, and the vendetta caused by this point can be completely discharged.

"Little brother, do you think it could be Huafang......" Director Chu's words were stopped by Zhou Lingwu's words, and Zhou Lingwu said: "Impossible, these things can't be prepared so fully without three months." (To be continued.) )
