At this moment, Matsumoto raised his hand. Seeing Matsumoto raise his hand, Miyamoto Kiyomasa signaled that he could stand up and speak.

Matsumoto has always been a subordinate of Miyamoto Kiyomasa, and when Miyamoto Kiyoshi was a middle-level official, Matsumoto was a low-level official under Miyamoto Kiyomasa.

And now, Miyamoto Kiyomasa has become the No. 3 person in the Public Security Investigation Department, and Matsumoto Ting has sat in the position of a middle-level official of the original Miyamoto Kiyomasa.

Matsumoto Ting stood up and said: "Greetings, I am the head of the Public Security Investigation Department, my name is Matsumoto Ting, the video just now was reported by me, and I firmly believe that this is the crime notice." ”

This sentence caused Maorishi to look at him, and as a young man, Maorishi was a little dissatisfied with Matsumoto's statement, which was tantamount to denying his judgment.

Miyamoto Kiyomasa said, "Go on." ”

"If this video can be determined to be a crime notice, can we conclude that the power outage before the explosion was also premeditated?" Matsumoto said. ”

As soon as he said this, it immediately aroused discussion among the participants, and even Morishi had to admit that Matsumoto's words were very reasonable.

Matsumoto continued, "I investigated and found that the widespread power outage around the city hall was caused by a hacker attack on the power company by an employee of TEPCO who illegally connected the Internet, which eventually led to the power outage. ”

An official from the Metropolitan Police Department immediately confirmed Matsumoto's account.

Matsumoto nodded and continued: "Just now, Section Chief Fujiki said that the source of the teaser video cannot be traced because the other party has superb hacking skills, and TEPCO also caused the power outage because of a hacker attack, can the two be connected?" ”

At this moment, Mao Lishi looked at Matsumoto Ting with wide eyes, he has been a top student since he was a child, and in high school, there was a very famous high school detective, but the Matsumoto Ting in front of him far surpassed himself in both investigation and analytical reasoning.

Matsumoto's remarks also sparked discussion among the participants, and if the two clues were linked, it could indeed prove that the video was a crime warning.

Matsumoto continued, "Moreover, I consulted with an expert, and the power system around the city hall has backup power, but it takes 10 minutes to start. Section Chief Fujiki said that in these 10 minutes, the camera at the city hall also failed due to a power outage, what does this mean? ”

"It means that the terrorists planted the bomb and evacuated the scene within these 10 minutes!" Mao Lishi couldn't help but say.

Matsumoto nodded and said, "That's it, but doesn't it also mean that the bomb used in the terrorist attack has been brought to the building a long time ago?" Of course, I don't know much about bombs, because I don't think the bomb could have been brought in on the same day to cause an explosion of that magnitude, right? ”

The head of the security section of the town hall said, "We are very sure that no one brought anything similar to a bomb that day, and the bomb should have been sent to the city hall before, which is a dereliction of duty." ”

Kiyomasa Miyamoto said: "Now is not the time to hold you accountable, and since we are talking about bombs, I will ask Goro Kato, the head of the Scientific Investigation Division of the Metropolitan Police Department, to explain it to you." ”

Goro Kato stood up, he was a chubby, balding middle-aged man, more like a university professor than a section chief of the Metropolitan Police Department.

"Before I talk about bombs, I have to say a few things about the construction of the staircase in the town hall," he said. The town hall building is not a simple reinforced concrete structure, and in order to protect against earthquakes of magnitude 9 or higher, the town hall building has four pillars that support the building. The pillars are built using state-of-the-art industrial methods and are extremely strong. Bombs in general are absolutely indestructible! ”

There was another uproar at the venue, and someone immediately asked, "What kind of bomb is that?" It can't be a nuclear weapon, right? I've heard that I recently lost a nuclear weapon!! ”

"Don't talk nonsense, how can our country have a !! of nuclear weapons" One stood up and yelled!

Leng Qianqian said to Hu Fei'er and Lin Xiu: "Do you see this person? He is the head of the Ministry of Defense and an important subordinate of the Reaper 8, and he will never allow Japan's development of nuclear weapons to leak! ”

Lin Xiu and Hu Fei'er nodded, because they were the same ones who snatched the miniature nuclear weapon that Death 8 had developed with great difficulty.

Kiyomasa Miyamoto said, "Please be quiet, let's listen to Mr. Kato about the bomb." ”

Goro Kato lifted his glasses and said, "Please rest assured, it's not a nuclear weapon." When we analyzed the explosive residues, we found a large number of residues of aluminum, iron, magnesium and hydrogen atoms......"

"Mr. Kato, please speak in a language that everyone can understand." Miyamoto Kiyomasa said.

Goro Kato immediately nodded and said, "I understand, to put it simply, we found a large amount of thermite at the scene of the explosion, and everyone understands it at this point, right?" ”

Seeing that there were still many people in the audience who were confused, Goro Kato further explained: "The thermite reaction is a means of high-temperature combustion by using the reducing properties of metal aluminum. For example, when forging steel, extremely high temperatures are required to achieve seamless welding of the steel, which relies on thermite reaction. ”

An audience member asked, "How did the terrorists get such a high-end thing?" ”

Goro Kato shook his head and said: "Thermite is not a high-end thing, as I said, it is widely used in welding and cutting, the easiest way is to mix iron oxide and aluminum powder and ignite, so that it can produce a high temperature of more than 3000 degrees Celsius!" ”

Maori stood up and asked, "Iron oxide and aluminum powder?" Isn't it hard to get something like this? I remember when I was in college, I had these materials in the lab. ”

Goro Kato nodded and said, "That's it, but such a simple and easy-to-get material can be turned into a high-temperature incendiary bomb, and at a high temperature of 3,000 degrees Celsius, even the support columns made of new materials in the city hall can be melted." ”

Matsumoto said, "I probably understand what you said, but I don't understand, if it is just a high temperature, it will only melt the supporting columns of the city hall building, and at most the building will disintegrate, but why such a violent explosion?" ”

Goro Kato sighed and said, "This is the shrewdness of the terrorists, as a result of the thermite reaction, which caused the fire prevention system in the city hall building to be activated, and a large amount of water was sprayed out. ”

Matsumoto was puzzled and said, "Shouldn't the fire be extinguished?" ”

Goro Kato said: "No, not only will the fire not be extinguished by water, but it will also cause an explosion!! ”
