More and more evidence points to Pastor Lowe, and it stands to reason that if one person hates another, he is unlikely to be so eager to help others unless he has some purpose. Pastor Luo took the initiative to go to Chen Zhaodi's house to replace the aging gas pipes, and his purpose was almost all thought of by the criminal police officers present.

I am afraid that the chemicals that burned when it was hot were smeared at that time. Some time ago, the weather gradually cooled, under the normal temperature, chemical reactions will not occur, but if the weather is better on a sunny day, as long as the temperature is not too low, more than 20 degrees Celsius, the use of concentrated light can produce enough heat energy to assist chemical combustion.

After autumn, the rain in Chongqing is not as frequent as in summer, and the number of sunny days is increasing, so if you want to implement spotlight in a certain period of time, unless it is really a beautiful day, it is relatively easy to complete.

The residents who live here know Pastor Luo very well, and in the eyes of everyone, Pastor Luo treats people quite well, but everyone doesn't see him often. Pastor Lowe spends most of his time in the church, and only in the evenings does Pastor Lowe go home to rest.

Shen Cheng calculated the time, and then asked if the residents had seen Pastor Luo's abnormal reaction on the night of Luo Danan's murder. A few residents thought about it carefully, and then someone suddenly remembered that one night Pastor Lowe had suddenly hurried out of his house.

At that time, it was only about seven o'clock in the evening, and it was just getting dark in Chongqing. Many residents sat in front of the door chatting, only to see Pastor Lo suddenly run out of the door, and before he could even close the door, he ran away. Speaking of one resident, many residents remembered, and with the support of many people, in the end, everyone confirmed that the night when Pastor Luo ran out of his house was the day Luo Danan died.

After extracting a lot of evidence, Shen Cheng returned to the police station with the criminal police, and the case suddenly became very clear, the work of chasing Pastor Luo continued, and the police station continued to sort out the evidence handed over to the procuratorate. In the evening, people from the criminal department came, and the results of another test had come out.

Regardless of the principles of mechanics, this time, their experiments seemed to be very smooth. The location of their experiment was directly chosen in the same place, that is, Pastor Luo's house and Chen Zhaodi's house. They placed an empty cylinder in the same place where Chen Zhaodi's house had placed the gas canister, and tied a used gas pipe to it.

In addition, the gas pipes were smeared with the same chemical that had been found in Pastor Lowe's home. Subsequently, the staff of the criminal department used a long-distance condenser to concentrate the light on the gas pipe, and it turned out that the light propagated in a straight line and indeed reached the predetermined position.

The staff of the criminal department used a telescope during the test, but because the distance was too long, the gas pipe was too small, so they had to use a telescope to see if the light had gathered in the designated position. And in the list of evidence found from Pastor Lowe's house, there is a telescope.

The temperature on the day of the test was not higher than that on the day of the explosion, and it took more than 20 minutes for the staff to gather light before the gas pipe suddenly burst into flames. By comparing the same conditions, the temperature on the day of the explosion was very high, and in that case, it would only take a few minutes for the gas pipe to burn.

When the fire is fired, the gas spreads quickly from the gas tank into the gas pipe, and an explosion is most likely to occur. The murderer definitely pinched the time, if the temperature was high, he would gather the light later, and if the temperature was low, he would concentrate the light earlier, the purpose was to ignite the chemicals, burn the trachea, and cause an explosion when Chen Zhaodi opened fire.

The cause of the bombing has also been clarified, and there are fewer and fewer suspicious points in the case, and so far, we have not been able to figure out the only things we have seen on the construction site. The haunted construction site, I can't tell whether it's one person or two people, it's a magical feeling, if it weren't for me and Shen Cheng seeing it with our own eyes, maybe I wouldn't understand what the other workers meant.

In the night, I could clearly see two black shadows, but the two black shadows overlapped so high that they almost kneaded together. Because the murderer used physical methods twice in a row to commit the crime, Shen Cheng and I also considered whether the murderer used the dark environment and the principle of optics from the perspective of physics to make people's vision deviate.

But in the end, we couldn't find the principle in the content of optics that would cause such a visual bias. Besides, more than one person saw it, even if he could use some kind of blinding method, it was too difficult to deceive so many pairs of eyes, and besides, Shen Cheng and I saw it at the same time.

Helplessly, Shen Cheng and I ruled out this possibility again.

So far, Shen Cheng and I have jointly deduced the reason why the murderer returned to the construction site, and the principle of using Dashi to kill people, Shen Cheng alone speculated that the murderer conspired with Chen Zhaodi to kill Luo Danan and then killed people, Luo Danan was introduced into the construction site with money, this is a murder case related to religion, and Shen Cheng found the suspect Pastor Luo based on these, and I only speculated how the murderer ignited the gas canister.

Many of Shen Cheng's speculations have not been confirmed, but I have no way to refute him, and perhaps, when the police catch Pastor Luo, I will really lose.

As time passed, the people in the police station learned that Shen Cheng and I were competing to solve the case, and Shen Cheng's situation was very good, which made the people in the police station keep whispering, and I heard what everyone was saying. They are saying that Shen Cheng is still powerful, and I am in vain.

When it was almost dark, Shen Nuo and Jiang Jun came to the police station, and as soon as Shen Nuo entered the office, he looked at Shen Cheng angrily. At this moment, Shen Cheng was sitting at his desk, there was a sneer on the corner of his mouth, Shen Nuo didn't say anything in the end, she took my hand and dragged me out of the office.

Standing face-to-face with Shen Nuo, the fragrance on her body came to her nose.

"You bet with him, why didn't you tell me." Shen Nuo complained.

Me: "It's useless to tell you. ”

Shen Nuo: "I can help you!" ”

I shook my head: "Since it's a bet, I don't want anyone to help, he relies on himself, and I have to rely on myself." ”

Shen Nuo: "What's the bet?" ”

Me: "Task Force Leader, or a clue I'm interested in." ”

Shen Nuo was slightly stunned, it seemed that even she didn't expect Shen Cheng to use this to bet with me. However, Shen Nuo still sighed and said that if she had known earlier, she might have been able to help me win the bet.

Me: "Shen Nuo, in fact, I'm curious why in your heart, he is an omnipotent person. And why, do you think my self-confidence will be shattered by him? ”

Shen Nuo frowned, after cutting her hair short, she was much more mature and stable than when she was in G City: "He is such a person, isn't the current situation very unfavorable to you?" ”

Shen Nuo has already asked people about the progress of the current case, I didn't answer, Shen Nuo is right, the current form is very unfavorable to me, but the results have not come out yet, I will not give up. The weird feeling in my heart continued, and I always felt that something was wrong.

When he returned to the office, Jiang Jun was talking to Shen Cheng, and Shen Cheng's attitude towards Jiang Jun was okay.

Shen Cheng told Jiang Jun that banning the killer organization was not something that could be accomplished in a day or two, and that the public security organs in Chongqing had been preparing for this for several years. Shen Cheng made an analysis to Jiang Jun, and he, like me, also thought that Wang Xin would not have an accident. For the killer organization, it was easy for them to kill Wang Xin, but they didn't do it several times, which proves that Wang Xin still has the value of living.

Hearing Shen Cheng's analysis, Jiang Jun breathed a sigh of relief. Jiang Jun turned around: "Professor Li, I have been moldy in the hotel for the past two days, I have figured it out, it is not a way to hide in the hotel all day, you let me follow you to handle the case." ”

Jiang Jun offered to handle the case with me, and I did not hesitate and directly nodded and agreed.

At eight o'clock in the evening, Jiang Jun and I were about to go back to the hotel, when the criminal policemen who had gone out to carry out the arrest work ran back. The criminal police conducted a search in Chongqing, but as a result, Pastor Luo's people were not found, but the body was found.

Another person died, the suspect died, and we were all stunned in the office......
