This action was huge. The alarm sounded, and all residents in several buildings near the single apartment were evacuated. Special teams entered and sent the items to the laboratory. After analysis, this thing was called xxxx. It is used for industrial and medical purposes. The radiation capacity is relatively weak and its activity is relatively poor... In the saying goes, the radiation range is very small and the damage is relatively low. Unless it is a relatively long period of close contact, it will cause irreversible radiation damage to people.

All the people who entered the room were admitted to the hospital for observation, and Su Cheng and Zuo Luo were in the same ward.

Su Cheng: "I suddenly wanted to overturn the inference that the chemistry teacher was the murderer."

Zuo Luo said: "How can a teacher who is proficient in chemistry use physics to kill people, right?"

A physical evidence team member in the same room reminded: "Two, chemistry is a secondary discipline in physics, but it is just a relatively special discipline. To be precise, nuclear belongs to energy."

While talking, Bai Xue and the others came and asked with concern: "Is it okay?"

The doctor came in: "After multiple tests, your sperm is normal and not affected. You can be discharged from the hospital in the afternoon."

The atmosphere was awkward for a moment, and Su Cheng raised his left hand and said, "Iron Palm Floating on the Water." Explained the inspection process.

Zuo Luobing changed the topic: "What is the progress in the case?"

Everyone sat down and Fang Ling said, "This thing is called xxxx, it is from the A-big boiler research department. The last inspection was four days ago, and he was still there."

Su Cheng said: "The thief was caught?"

Fang Ling nodded: "His name is Huang Ye, he is a sophomore and works part-time in the graduate school."

"What is the relationship between yellow leaves and Yuhua?"

Fang Ling asked: "Yu Hua became the school beauty in her first year of high school. At that time, there was a strong competitor in the second year of high school, named Li Shuwen. It was rumored that Yu Hua used some means to force Li Shuwen to withdraw from the competition, and handed over the throne of the social queen, and transferred to an ordinary high school. Huang Ye is Li Shuwen's boyfriend."

Zuo Luo patted his forehead: "Su Cheng, you are a disaster. If you are stubborn, you will throw away the real murderer."

Fang Ling nodded: "Huang Ye has confessed that someone sent an indecent video of Huang Ye and Li Shuwen to Li Shuwen on his mobile phone, forcing Huang Ye to transfer to international high school. However, they have never been sure whether Yu Hua was the mastermind. Seven days ago, the third day after Du Yiyi committed suicide, Li Shuwen and Yu Hua met at a student day party. Yu Hua was very conscientious and apologized to her and told her that the video had been deleted. Please rest assured. Li Shuwen and Huang Ye realized that it was Yu Hua's doing it, so they conspired to take revenge."

Su Cheng said: "Wait, since they all want to kill people with radiation, why should they attack Hua?"

Fang Ling said: "The case is full of surprises. Li Shuwen's younger brother is a first-year student in the international high school. Twenty minutes before the incident, Li's younger brother went back to the teaching building to get notes. At the same time, he was the first group of people to find Yu Hua's body. Among the four onlookers, he also went up to check Yu Hua's situation and asked another student to call the first aid."

Song Kai asked proudly: "Consultant, head, are you surprised or not? We are still very powerful."

Zuo Luo asked back: "Is Li Shuwen's younger brother recruited?"

"No, he said he went to the teaching building to get notes. His classroom was on the fifth floor. After taking the notes, he went downstairs. He heard the sound and went over to see Yu Hua falling from the building. He denied that he had seen Yu Hua before. He asked him why he didn't take the initiative to explain to the police that he was in the teaching building. Brother Li replied that he was very scared when he found out that the deceased was Yu Hua, because he just learned about his sister and Yu Hua, and he hated Yu Hua very much. Yu Hua died, and he was afraid that the police would suspect him."

Zuo Luo said: "What do you think?"

Song Kai said: "We think Yu Hua is likely to go back to the teaching building to get his own things. Brother Li followed him after discovering it. The two sides had a dispute outside the seventh floor. Brother Li practiced judo for many years. We suspected that Yu Hua was thrown out. When Brother Li came forward to first aid, he sorted out Yu Hua's clothes that were caught, so that we did not find any flaws."

Su Cheng nodded: "There is some reason, but it is Li Shuwen's younger brother who is facing the police for the first time. What do you think of the interrogation process?"

Fang Ling shook his head: "It seems that what he said is the truth, but he is very excited and nervous."

Zuo Luoshen exhaled: "This case is becoming more and more interesting."

Su Cheng raised his hand: "Stop...there are more and more clues, more and more suspects, and the pool water is getting deeper and deeper. I don't like this. I want to use my method to analyze the case once."

Su Cheng said: "First of all, Li Shuwen, who competes with Yu Hua for school beauty. Li Shuwen's boyfriend got xx dangerous goods. Normally, killing Yu Hua is just a matter of time, so Li Shuwen and his boyfriend Huang Ye will not be the murderer logically."

Su Cheng said again: "Li Shuwen's younger brother, a martial arts practitioner, is very big. At that time, he and Yu Hua were in the teaching building and were able to kill people. Li Shuwen's younger brother was a suspect, but from the interrogation, he did not look like the murderer."

Su Cheng said again: "The chemistry teacher has the motivation to kill Yuhua and can also create time to kill Yuhua. But I don't think the chemistry teacher's physical strength is very good. I don't think a scholar in his fifties could throw Yuhua out of the teaching building, and Yuhua did not resist during this period." If there is physical conflict, an autopsy can be found. Yuhua's corpse has no trace of physical conflict.

Zuo Luo asked: "You mean that a chemistry teacher can rule out the suspicion?"

Su Cheng said: "I suggest interrogating Li Shuwen's younger brother. If he can be ruled out, the murderer can only be a chemistry teacher."

Zuo Luo was dissatisfied: "This is how the detective handles the case? Now it is obvious that Li Shuwen's younger brother is the most suspicious. What is your basis?"

Su Cheng replied: "Li Shuwen's younger brother is only sixteen years old. If he kills someone, he will definitely pee in the first instance unless he is an antisocial personality. Although I don't think the chemistry teacher has the strength to throw Yu Hua out of the teaching building, I always feel that he has the ability to do it. I especially care about a suspicious place. Yu Hua is like a social queen. He did not update his blog when he attended the party on the night of his death. Moreover, Yu Hua is not a student on campus. She ended the party early and went to the teaching building. Would this behavior be too weird?"

Zuo Luo said: "Since that's the case, the troops are divided into two groups, Bai Xue, you follow Su Cheng."

...

Zuo Luo interrogated Li Shuwen's younger brother: "Student Xiao Li, someone proved that you bought a mask and went to the teaching building."

Li Shuwen's younger brother said, "Okay, I'll tell the truth, I just want to beat her up."

Because Li Shuwen's younger brother was underage, he was accompanied by a legal counsel sent by the police station. The legal counsel reminded: "Subjectively thought, objectively, you must make it clear."

Li Shuwen's younger brother looked up and looked at Zuo Luo hu: "It didn't happen. I wanted to vent my anger on my sister."

Zuo Luo slowly knocked the pen in his hand on the table. When he came back, he knocked it again. He looked at Li Shuwen's younger brother in scrutiny, and asked after a long time: "What do you think of flowers?"

"view?"

"Yes, appearance, human nature, etc."

"I...I don't know."

Zuo Luo said: "Student Xiao Li, do you know how much trouble you are in now?"

Li Shuwen's younger brother said, "I didn't kill anyone."

This sentence is interesting. The implicit meaning of this sentence is that Li Shuwen's younger brother actually knows something, but he doesn't want to say it or make it up again. Li Shuwen's younger brother has never faced the police, but has had perjury before, indicating that there must be problems in it.

Zuo Luo looked at Li Shuwen's younger brother: "Did you see something?"

Li Shuwen's younger brother shook his head: "No, you can catch me, I didn't kill anyone anyway."

Zuo Luo thought, and said, "I remember when I was in the police school, there was a question like this. A swimming coach was preparing to divorce because his wife cheated. One day, the coach rode his bike home. He passed by Qinghu and heard someone calling for help. So he went down to the edge of Qinghu embankment. He saw his wife calling for help, and his lover was struggling in the water."

Li Shuwen's younger brother asked: "As soon as the coach left, ask if the coach is guilty?"

"No, the coach jumped into the water."

Li Shuwen's younger brother laughed: "It turns out he is a gentleman who repays grievances with kindness. There are not many such good people, so he should be a national treasure-level figure."

Zuo Luo said: "You guessed wrong again. The coach did not save people, but swam near his wife's lover and admired his lover's love husband and finally drowned."

"ah?"

Zuo Luo said: "This question is not difficult, the answer is that the coach is innocent, because he is not a legal obligation to rescue the person. If the police and firefighters do not save him, it is a crime. Secondly, it is not the coach that caused the lover to fall into the water, and he has no obligation to rescue him. But this is a real case that happened in Qinghu. Afterwards, the coach's wife committed suicide. The coach also lived in guilt and left City A. Before leaving, he wrote an apology letter to his lover's family."

"What do you want to say?"

"Yu Hua did use conspiracy to cause your sister to lose something, but first of all, your sister was wrong. After all, she was caught in the trap of doing things. It's nothing to dare to act. Secondly, Yu Hua is not a person who is extremely guilty. She is a seventeen-year-old girl. When she died, you watched her die indifferently. Do you feel like that coach, you have the ability to save her?"

Li Shuwen's younger brother retorted: "How is it possible? That was a matter of a moment..."

The legal counsel immediately said: "Left Team, you are luring your confession, and my client may not be responsible for this sentence."

Zuo Luo nodded and looked at Li Shuwen's younger brother: "Can you tell me about the situation at that time?"

Li Shuwen's younger brother shook his head: "I don't know anything."

If Yu Hua committed suicide or an accident, Li Shuwen's younger brother would not have to bear it. It is very likely that Li Shuwen's younger brother knew who the murderer was, and the murderer had something to do with him.

Zuo Luo suddenly asked: "Are you a chemistry top student recognized by international high schools?"

"Yes..." Li Shuwen's younger brother asked tough, "What?"

Zuo Luoshen breathed and said, "I think I know the process. If I was not wrong, the process is like this. You heard about your sister being framed. Then at about eleven half of that night, you saw Yu Hua. Yu Hua walked towards the teaching building and you followed. Maybe you wanted to reason with her, maybe you wanted to beat her up, but you found that Yu Hua was meeting someone, and this person showed considerable hostility towards Hua, so you listened and watched, and suddenly Yu Hua died."

Li Shuwen's younger brother was calm: "Police officer, you are so good at making up stories."

Zuo Luo said: "I can track down things in very detailed details. I would like to remind you that perjury is illegal. If you have a criminal record, you will not be able to go to many countries."

The legal counsel said in Li Shuwen's ear: "He is not interested in your perjury, but if you don't say anything, he will take your crime seriously."

Li Shuwen's younger brother thought for a while: "Yes, I saw Yu Hua walk towards the teaching building and wanted to teach her a lesson. I temporarily bought a mask from the small shop, and I didn't want to be identified by her. After a few minutes, I saw Yu Hua in the corridor on the seventh floor, so I went up. When I arrived at the seventh floor, I saw her fall down..."

"How did you fall?"

Li Shuwen's younger brother made an action: "Yu Yue? I forgot... I have a witness, and my girlfriend is there too. She kept advising me downstairs not to do stupid things, so I remembered to buy a mask. She looked downstairs. She didn't see Yu Hua in the corridor, but when she saw me at the entrance of the stairs, she could prove that when Yu Hua fell from the building, I was at the entrance of the stairs, and Yu Hua fell from another stairs, with a distance of at least eighteen meters."

Zuo Luo asked: "Why didn't you say it before?"

Li Shuwen's younger brother said, "I don't want to cause trouble."

...

Su Cheng: "Suppose the chemistry teacher kills people, and he adjusts the time to forge absent evidence, he needs precise time. Why didn't Yu Hua take photos at the party and upload them? Because Yu Hua went to the party not to attend the party. She might have gone to get something and was asked to go to the teaching building. The chemistry teacher did not go to the party, so how did he ask her? We checked the phone and social software."

Shiraki said: "So we have to solve this puzzle first, right?"

Su Cheng said: "This puzzle is not very important. I just wonder how to kill people... But it's okay to go and see the party scene first. It's strange. A professional chemistry expert, why does the traces of murder have no chemical factors in it?" This is the tendency for murder cases. The murderer is more accustomed to using his strengths to attack the target's shortcomings.

Bai Xue said: "According to the transcript, the party owner said that Yu Hua borrowed the bathroom on the second floor of the villa and left in a hurry. The party owner said that the second floor was a private residence and it was not open at the party. His parents were on the second floor. However, because there were three bathrooms on the first floor and Yu Hua was anxious, the party owner took her to the second floor. There were master bedrooms on the second floor, two second bedrooms, two guest rooms, study rooms, guest rooms and one second bedroom, and there were no separate bathrooms on the second floor. There were shared bathrooms on the second floor."

Su Cheng said: "Give me the party host phone number, I'll contact you, drive."

...

Su Cheng entered the bathroom on the second floor of the villa, which was a very ordinary bathroom, a seated toilet, a sink, and a glass-separated shower room.

The party host introduced: "I am from Linyuan County and have many relatives. My father values ​​feelings. When relatives come to A City, they will ask them to stay as overnight as possible to fulfill their friendship as the landlord. They use the bathroom."

Su Cheng asked: "What about your mother's attitude?"

The party host smiled and replied: "Of course my mom welcomes you too."

Su Cheng also smiled: "Since you are welcome, why should you install a special ultraviolet lamp for bacterial disinfection?"

The party host was very unhappy: "What do you mean? Can't my mom have a cleanliness obsession?"

"But the guests didn't know that there was an ultraviolet light inside the lights that were turned on together." Su Cheng turned on the lights, and the three lights were on together, and there was no ultraviolet light. He pressed the other two switches and turned off the two lights, and the bathroom was filled with purple. Su Cheng said: "Baixue, let's go."

Ultraviolet lights are currently commonly used for home disinfection, so it is best not to be included in it. The advantage is that as long as the ultraviolet light is turned off, you can enter the room directly without any side effects. Ultraviolet lights have special effects against a variety of viruses and bacteria and have strong sterilization ability.
