Man-made or accidental? Until the fire department's final conclusion is down, no amount of reasonable inference can be a reason to solve the case. However, Uncle Maori surprisingly restored the scene at that time.

Based on the relationship between Ryoshi Koyama and Hiroshi Nagasawa, Uncle Mori speculated that Ryoshi Koyama may have manipulated the gas sensor alarm and gas pipe, causing the gas leak and the alarm malfunctioning. When the concentration of gas in the house reached a certain range, Koyama ignited the gas with an item such as a lighter, resulting in an instantaneous explosion.

The police from the forensic department did find a few lighters in the room, but they were not sure which of these lighters was the one used by Koyama Lian for the time being.

"However, I remember that the liquefied gas will be mixed with hydrogen sulfide gas that smells of rotten eggs, if it is really like what the Maori detective said, can't Yue Zhiren and Nagasawa Hao smell it?" Sera asked.

Mori Kogoro was gone, but in order to keep his majesty as a detective, he had to say, "Since Koyama can use his hands on the siren, maybe even the gas in the liquefied gas tank has been replaced, and he is a veteran employee of the hotel, so it shouldn't be difficult to do this kind of thing." ”

While observing the wreckage and listening to their conversation, Conan suddenly turned on the elementary school mode: "Ahhh It's weird! These pieces are big and big, and small and small! ”

"Stupid, isn't that normal, it's good to have so many fragments left behind in such a serious explosion." Mori Kogoro said.

"It's so strange, it stands to reason that if the gas explosion in the indoor air causes the liquefied gas tank to detonate, it is impossible for the liquefied gas tank to be blown into so many pieces, because there is less gas in the gas tank at this time, and it should be that the upper part of the liquefied gas tank is intact, and the lower part is blown open, and it is impossible to be blown apart." Shiliang said.

"So this time they are all unlucky, and God won't even help them!" Maori Kogoro is a little angry, these guys who don't know the height of the sky are really annoying.

"Hey, Conan, are you still here?" Ji Haihong led a group of children to find him, and Xiaolan and Yuanzi followed behind them.

"Lan, you guys stay in the room first, first when Dad is handling the case." Mori Kogoro said.

Unexpectedly, this sentence aroused the children's interest: "Handle the case? Another case has happened? Was that explosion accidental or man-made? ”

"This and this, don't ask too much, children, it's all confidential." Although Mori Kogoro wanted to say that it was artificial, but Seliang's inference just now made him feel uncertain.

Shiliang secretly looked at the gray plain hiding behind Xiaolan, I don't know why, this child seems to be always hiding from himself? Or is she afraid of life?

Ji Haihong walked to Conan's side, and blurted out as soon as he saw the wreckage: "Yo, it explodes directly from the inside, it's really too rare and rare, because it's very important, so I have to say it twice." ”

"Really? Really exploded from the inside? Conan almost forgot that this person next to him was not an expert, he must have encountered a lot of explosives on the battlefield, and his understanding of this kind of thing must be very profound!

"Of course, but this is the first time I've seen a liquefied gas tank blown up like this, is there a high-explosive grenade stuffed in it?"

So that's the case, so that's the case, then from this point of view, the criminal's modus operandi is clear, and those small and very abnormal fragments are also explained!

"So, this case can't be fully investigated yet, and we still need to interrogate Koyama before we can ...... further" Mori Kogoro, who was communicating with Officer Twilight, suddenly felt black in front of him and lost consciousness.

Ji Haihong witnessed the whole process of Conan's sneak attack on Uncle Maori, and also saw Uncle Maori automatically sit on the ground in a very comfortable posture with his back against the wall after losing consciousness.

In fact, Uncle Maori's subconscious sense of self-protection is still very strong!

"Could it be that the Maori detective has become 'sleeping Kogoro' again?" Sera is very curious, but she has hardly seen the famous "Sleeping Kogoro".

Conan is hidden behind Ji Haihong, Ji Haihong covers Conan, it is not the first time for the two to do this kind of thing, they have long been familiar with the road and have a tacit understanding.

"Ladies and gentlemen, after the investigation of my detective Kogoro Mori, I finally know what the criminal's modus operandi is."

"Oh." The response of the police was uneventful, they were used to it, and while they were still wondering who the culprit was, the Maori detectives already knew the modus operandi of the criminal.

"In fact, the criminal's motive for committing the crime this time is obvious, and the modus operandi is very simple, but he has drawn our attention to the accident, and the news often broadcasts some accidents that caused the explosion of liquefied gas tanks due to accidents, so our first reaction will also be 'This is an accident caused by an accident', besides, the result this time is still two dead and one injured, and ordinary criminals can't do such a dangerous thing for themselves."

"But that's not the case, according to my observations, when the explosion occurred, Koyama was arranging his wine glasses at the entrance, and he was standing right behind a wooden plank, so that he avoided the bad luck of being killed."

"Could it be that Xiao Shan Lian is the murderer?" Seliang asked.

"How to say it, it's one, then let's talk about his modus operandi, it's very simple, classmate Shiliang said that liquefied gas must be fully mixed with oxygen to have an instantaneous explosion effect, Ji Haihong also said, this kind of explosion is impossible to appear on ordinary liquefied gas tanks, because Ji Haihong's friends are experts in relevant aspects, his words can be believed, then, the only explanation is that the liquefied gas tank was modified by Xiaoshan Lian."

"Could it be that explosives are installed in liquefied gas tanks?" Officer Twilight asked.

"Impossible, not to mention whether explosives will produce an instantaneous explosion effect, gunpowder will leave traces after exploding, so Xiao Shan Lian did move his hands and feet in the liquefied gas tank, but he used not a bomb, but an oxygen tank and an electric spark device."

"Oxygen tanks? Electric spark? Officer Twilight understood something.

"That's right, the material of the oxygen tank and the liquefied gas tank is similar, even if it is inspected, it will not arouse suspicion, and the electric spark device is remotely controlled, and the prisoner will make a spark at the right time to ignite the liquefied gas in the tank that is highly mixed with oxygen, which can produce an instantaneous explosion and kill people, which is why there are very small metal fragments at the scene, in fact, this fragment is not a liquefied gas tank, but a miniature oxygen tank."

"So, what about the EDM device?"

"The EDM device itself is very small, such as the EDM device in the lighter, under the power of this explosion, it will either be blown up beyond recognition, or it will be ignored by the people of the forensic department, because those wreckage are all evidence, I can't touch it, so please check it carefully in the forensic department, maybe you can still find the electric spark device."

Several police officers from the Forensic Identification Division immediately rummaged through the plastic sheeting for evidence, and sure enough, they found a blackened suspicious object. From the outside, it's really an EDM device, and there's something like a circuit board on it.

"Brother Maori is really powerful, now we only need to find the remote control, we can lock who the prisoner is, I will go to the hospital now to personally search the prisoner's clothes, he was seriously injured by the explosion, there must be no chance to discard the evidence again."

"Let's not talk about the remote control," said Kogoro Mori, "do you really think that the prisoner is the only one who is Koyama Lian." ”

"Why, could it be that there are other accomplices outside the room to assist? By the way, if you modify the liquefied gas tank, it is indeed very likely that someone else will help, and we will investigate immediately......"

"Uncle Maori, I also think there should be only one prisoner." Ji Haihong said suddenly.

Mori Kogoro, or Conan, was silent for a while, and then said, "No, there are indeed two prisoners, and the other prisoner is the chef who was killed, Yue Zhiren." ”

"What? How is this possible! Seliang was surprised, this was obviously a vendetta murder, and Yue Zhiren had nothing to do with Nagasawa Hao, how could he be involved in such an operation? He still has a family and a daughter, so he can't abandon it like this......

"Officer Takagi said that Yue Zhiren took out a huge amount of accident insurance before he died."

"It's hard to ...... Could it be said? The policemen who guessed the ending were stunned.

"That's right, the chef deals with liquefied gas tanks every day, they know how to modify liquefied gas tanks, and they are also familiar with the manufacturers who provide liquefied gas tanks, I think, Xiaoshan Lian wants to kill Nagasawa Hao, but there is no good way, and then he found Yue Zhiren, after communication, he used the factors of Yue Zhiren's family poverty and his daughter's serious illness to let Yue Zhiren buy accident insurance, and then deliberately showed favor to Nagasawa Hao, eased the relationship between the two, and then let Yue Zhiren modify the liquefied gas tank, and implemented the murder plan with Yue Zhiren, one wants the family to be happy, One wants revenge, it is easy to resonate between the two, they carefully planned this accident, and they are about to achieve their goals, Yue Zhiren wants to deceive the insurance to treat his family, and Xiaoshan Lian wants to take revenge without sanctions. ”

The atmosphere at the scene was very heavy, half loud, and Officer Twilight saluted Mori Kogoro solemnly: "Understood, I'll go to the hospital to search the remote control now." ”

"This should have been expected by Xiao Shan Lian, the remote control is likely to be hidden in the sole of his shoe, which is the easiest place to be overlooked."

Officer Twilight turned to leave, admiring the Maori brother. You know, if this plan is successful, not to mention what happens to Xiaoshan Lian, Yue Zhiren's family will receive a generous insurance payment, and his daughter will be saved.

Logically speaking, Nagasawa's powerful Xiaoshan Lian's wife was scattered, and she deserved to be used like this.

However, the law is the law, and the dignity of the law does not allow anyone to provoke it.

Yue Zhiren, but he used his life to interpret what father's love is. If ordinary people knew the truth, they would probably only say that it was Xiaoshan Lian's fault, and not tell Yue Zhiren's matter......
