"Very good, Minister Sakamoto, you have heard it. Do as brother Yumu said. There is not much time now." After hearing Xiaozhi's analysis, Mumu Sheriff immediately said to Sakamoto, Minister of the Ministry of railways.

"I see. Now it's the only way." Minister Sakamoto thought about it and now he can only trust Xiaozhi, so he mobilized all the people in the headquarters and began to turn the tram into other routes.

On the other hand, sheriff bainiao also received the notice from Sheriff Mu and sent a bomb disposal team to start looking for bombs at the rail junction.

Before six o'clock, the security party finally recovered all the five bombs safely. At the same time, the tram stopped after changing the line, and no one was injured. After the ring line crisis was lifted, Xiao Zhi drew the location of the bomb on the road map with a pen, hoping to guess the identity of the other party.

"I see. Old man, I'm not timid." After reading the road map for half an hour, Xiaozhi finally determined who the bomb maniac was.

"Brother Yumu, do you already know who the prisoner is?" Seeing Xiaozhi's angry appearance, the magistrate suddenly said that all they can count on now is Xiaozhi's analysis.

"Ah ~ take a closer look around where these bombs are placed to see if there is anything in common." Xiao Zhi took a map from one side and put it on the track map.

Then he drew the location of the bomb with a pen on the map. After reading the map, Sheriff Mu and they didn't find anything strange. On the contrary, Sheriff white bird saw it.

"I see. All the houses and buildings near these bombs are designed by British style, and they were designed by Professor sengu after he returned home. Is it him?" As a rich second generation, sheriff bainiao naturally has some understanding of architecture, so when he saw the map near the bomb on the map, he immediately thought of what Xiaozhi wanted to express.

"Now go to Professor sengu's house to investigate immediately. White bird, you go to the search warrant in the Bureau." Whether Xiao Zhi's analysis is correct or not, the sheriff will not give up on this matter. Even if he has a chance, he will find the prisoner, otherwise he can't afford the consequences.

Soon, Xiaozhi and his party came to morigu Di'er's home. In fact, before the bomb incident, there were several cases related to morigu Di'er not long ago.

Some time ago, almost all the buildings designed by sengu Di before he was 20 or 30 years old were set on fire. At that time, the security party thought that this thing was only done by people who hated sengu di er, so they didn't suspect sengu di er. Now it seems that they let go of a very ferocious criminal.

"Hoo ~"

"I see. Although such an accident is a little incredible, it is not impossible. You doubt me with this clue?" In the living room of morigu Di'er's family, morigu Di'er took a sip of his pipe, then looked at Mumu sheriff and Xiaozhi and said, looking leisurely.

"No, the prisoner is you. I can be 100% sure of that." Xiaozhi on one side determined that the other party was the bomber at the moment of seeing morigu Dier.

Evidence 1: there was a smell of gunpowder on morigu's body. He also smelled it when he came to each other's birthday party before. However, because morigu was an architectural designer, Xiao Zhi didn't care too much at that time.

But this time as like as two peas, the bomb that was found on the rails was smelled by Xiao Zhi, which is exactly the same as Moritani Jeji's smell. But this smell is only a small nose.

Evidence 2: Xiaozhi finds that morigu Di'er has been avoiding his sight since he first came, or unwilling to look at himself. This situation represents that the other party is guilty, or dissatisfied with himself, or both.

"Oh ~ I've heard the name of detective yumuyezhi for a long time. I don't know if you say I'm a prisoner. What evidence do you have?" Xiaozhi's words made morigu Dier stiff, and then quickly managed his expression.

A pair said leisurely as before, but Xiao Zhi can see that the other party is very nervous and his heart beats very fast. Xiao Zhi's ears, nose and eyes are not kidding, let alone such a close face-to-face distance.

"Yes, brother Yumu, tell me your reasoning." Mumu Sheriff can only listen to Xiaozhi's reasoning now, otherwise it is impossible to solve the case with his ability.

"If my analysis is correct, the most serious loss in the recent arson incident should be professor sengu. Are you right? Your house is almost completely submerged without fire, and it is impossible to renovate it."

"But you don't seem to care about it at all. There is also today's bomb incident. If I don't successfully dispose of the bomb, once the bomb explodes, you will lose the most."

"Because there are buildings designed by you near the place where you place the bomb. You said this at your birthday party before. It is said that many young architects lack awareness of beauty, and they should have a more sense of responsibility for their works."

"What you have done recently is to practice these words. I didn't think what you meant by these words at that time. However, after today's explosion and I saw the building you designed on the wall just now, I finally understood."

"The reason why you want to destroy your works is that you are dissatisfied with the works you designed before, or you are satisfied with the original drawings of these designs, but you are dissatisfied with the implementation effect."

"I see. These works are not completely symmetrical buildings." After hearing Xiaozhi's reasoning, Sheriff white bird also took a look at the photos hanging on the wall. Looking carefully, Sheriff white bird immediately found the mystery.
