Chapter 70

"Everybody, the bomb is not in the train we suspect, but between the tracks!"

In the knowledge of primary blasting skills, there is a method of detonating a bomb by using a photosensitive device. The blasting work under some special circumstances can be carried out by setting the induction degree of the light source receiver to the light.

The prisoner suggested that the bomb would explode after sunset, indicating that the bomb must be in a place where it can stably receive the light source, so it is likely to be installed on the train carriage or between the external tracks.

If the bomb is on the carriage, it does not need to be limited by the train speed. Therefore, the most likely place for the bomb is between the tracks that will temporarily block the sun due to the length of the carriage.

After explaining the reasoning process to the public, Bai yanzhenyu reminded: "Mumu police department, since the bomb is not on the train, now you can turn the train to other tracks. As long as it is separated from the loop line, there will be no danger of parking.

"I see. Now tell them to change the train track, and then go to the loop line to search for bombs."

Mu Mu Police Department agreed with Bai Yan Zhenyu's reasoning and immediately called the train dispatching department to select a train with the least passengers for the test.

Under the uneasy eyes of the police, the train changed lanes into other routes and reduced its speed to less than 60 kilometers.

Until the train stopped at a station, the explosion that everyone feared did not happen, and immediately everyone cheered.

The next action is very simple. Use the same way to help the remaining trains running on the ring line resolve the crisis.

Before sunset, the police came a good news. They found all the bombs installed by the prisoners between the tracks of the ring line and successfully dismantled them.

However, after the good news, another bad news came, that is, the amount of explosives in the five bombs is only a quarter of the total amount of stolen explosives, that is, the other party is ready to commit other crimes.

The white bird police officer sent by Mumu police department to investigate Okamoto Haoping also returned to the hospital at this time and reported to Mumu police department: "Mumu police department, I have investigated. Okamoto Haoping went to Izu early this morning."

"In that case, we can rule out the possibility of Okamoto's crime."

Mu Mu rubbed his eyebrows and said with a headache, "the next problem is to find out the prisoners and the remaining explosives, but now there is no useful clue."

Maori Kogoro, who had been looking through the case data, seemed to find some key information and said confidently, "Mumu police department, I have found the clue of the prisoner."

As soon as the eyes of the police department brightened at dusk, the whole person perked up and couldn't wait to ask, "brother Maori, tell me about it."

"Once the bomb explodes, the scope will not be small, so the prisoner's residence must not be the five places where the bomb is set on the ring line. Similarly, when Conan handles the pet box bomb, the countdown of the bomb stops for a period of time, which means that the prisoner's home is nearby."

"It's really yours, brother Maori."

The seemingly reasonable reasoning was recognized by police officer Mu Mu and excitedly arranged: "I remember that the nearest place to there is the children's Park and an apartment. Let's investigate that apartment now."

The vigorous Mumu police department immediately took officer bainiao and several subordinates to the apartment for investigation.

Two hours later, officer Mu and others returned from the loss and sighed wearily: "after our investigation, not only the residents of that apartment, but also the people living nearby, there is no possibility of committing a crime."

"Eh? Well, it seems that my reasoning is really wrong." Maori Kogoro, who was still in spring, suddenly became embarrassed.

During the period when Mumu police department went to investigate, Bai yanzhenyu and Conan were also analyzing the data of all recent relevant cases, and finally found a clue ignored by the police.

"Mumu police department, I think we may fall into the prisoner's thinking trap."

Under Conan's sign, Bai yanzhenyu came forward and reminded: "according to previous inference, the bombers and arsonists are a group of people, so their real purpose should be to retaliate against Mr. morigu. You see, the location of the bomb is the bridge designed by Mr. morigu."

"What?!"

Reminded by Bai Yan Zhenyu, Mu Mu police department and others began to read the information and found that the bridge was indeed designed by morigu Di'er, and morigu Di'er also won the best newcomer award of the Japanese Architectural Society.

After thinking for a long time, the police department said, "in this way, the real purpose of the prisoner is to prepare to blow up the bridge."

Baiyan Zhenyu nodded and suggested: "Mumu police department, we'd better go to Mr. sengu to investigate. Maybe we can find new clues."

"OK, let's go now."

Mu Mu's Police Department agreed to Bai Yan Zhenyu's proposal, so they all went to sengu Di'er's house together.

……

Morigu Di'er's house.

After learning the intentions of Bai Yan Zhenyu and others, morigu di er shook his head and said apologetically, "it's really a bit incredible by coincidence, but it's a pity that I can't think of anyone who would do such a bad thing."

The Mumu police department had expected that it might not be possible to ask the murderer's clue from morigu Di'er, but it was not too disappointed. Then he asked, "Mr. morigu, can you take us to your exhibition room?"

"Yes, come with me!" morigu di er hesitated a little, but finally agreed.

After taking the people into his exhibition room, morigu Di'er pointed to some pictures placed in the back and said, "the buildings you said are over there. They are my works before I was 30 years old."

People looked carefully at the pictures in the exhibition room and tried to find clues, but they found nothing.

At this time, Baiyan Zhenyu found an exhibition cabinet covered with black cloth in the corner behind the exhibition room and asked curiously, "Mr. sengu, what's in here?"

"This is..." Moritani's face slightly changed. After lifting the black cloth, he explained: "this is the model of sidomo city that I was responsible for designing and planning before."

"Seymour..."

After hearing the name, Conan, a colleague, suddenly moved in his heart and looked carefully at the buildings in the model.

As like as two peas, the street lights in the model of Conan were found to be exactly the same as the street lights that came from the countdown of the pet box bomb, and a strange idea occurred in the heart. Perhaps the prisoner was the one whom everyone had never suspected.

"Brother Zhenyu, I know who the prisoner is. Wait for you..."

Conan came to Bai Yan Zhenyu's ear, whispered his reasoning to Bai Yan Zhenyu, and then slipped out of the exhibition room to prepare for exposing the real prisoner.
