"Is Forensic Doctor Liu here?" Lu Weiwei walked to Forensic Doctor Liu's office with ease. When she saw the forensic assistant who was writing a report, she asked him: "Where is your master?"

"Busy." The forensic assistant looked at Lu Weiwei, as well as Gu Chen, Officer Wang and Officer Ding behind Lu Weiwei, and knew that things were not that simple.

Almost all of these people have become regular visitors to the technical department, and they often come to handle cases in the middle of the night. The forensic assistants have the urge to die.

"That's okay. I'll leave this to you. You can help us test it." Lu Weiwei took the sealed blue cylinder from Gu Chen's hand and handed it to the forensic assistant.

"What is this?" The forensic assistant instinctively shrank back.

"Maybe it's... poisonous gas." Lu Weiwei said.

The forensic assistant covered his mouth and nose: "Why did you bring poisonous gas here? Come with me."

Afterwards, everyone, led by a forensic assistant, came to a testing room and placed the gas bottle in a transparent container.

"Are you sure there is really poisonous gas in this thing?" the forensic assistant asked.

Lu Weiwei nodded fiercely: "Is it possible that I still lied to you?"

"But I'm busy, so I'd better wait for Forensic Doctor Liu to come over and do the test." The forensic assistant looked repulsive and said, "You guys are the only ones who come here every two days. As soon as you come, I have to work overtime.

Do you really think I’m a big shot in the forensic field?”

"It's hard...isn't it?" Lu Weiwei stared and asked weakly.

The forensic assistant was stunned at first, and was also confused by such words, but he quickly reacted and immediately changed his face and laughed: "Haha, I didn't expect that I was so low-key and still found out by you. Tell me, when?"

want?"

"The sooner the better, we'll wait here." Gu Chen behind him also said.

"Okay, who makes me a big shot in the forensic field?" The forensic assistant suddenly swelled.

He naturally changed into work clothes, put on white gloves and a gas mask, and prepared to conduct testing in the isolation room.

"You guys stay outside for a while and don't come close." The tone of the forensic assistant's words changed instantly. He imitated the tone of his master, Forensic Liu, and directed the people in front of him.

Everyone also obeyed the arrangement and waited quietly outside the door of the testing room.

"Um..." Officer Wang couldn't help but worry: "Can this little forensic doctor do it?"

"It should be no problem." Gu Chen seemed to know Officer Wang's worries, and said with a faint smile: "He has been working with forensic doctor Liu for a long time, so there should be no problem in terms of testing."

"I hope so." Officer Ding nodded his chin and said, "Let's take a look and talk about it."

Officer Wang was thinking about it in his mind, thinking that he usually asked forensic doctor Liu to do the test, but now he was his apprentice. He didn't know how long it would take.

After a long time, the forensic assistant in the isolation room took off his mask and gloves and walked out of the room.

Under the curious eyes of everyone, he said calmly: "You are right, this blue bottle does contain highly toxic gases, and it is easy to evaporate."

"Are you sure?" Gu Chen asked.

"Is there any falsehood? I will write an analysis report for you later."

"Okay, with your analysis report, our case will be closed soon." Lu Weiwei was quite excited, she knew that this was the key to the problem.

Once it is determined that Zhang Wen filled the tires with poisonous gas, this guy will not be able to escape his involvement.

"Now summon Zhang Wen immediately. I wonder how long this guy will continue to act."

Officer Wang had a long-lost smile on his face. The case was progressing faster than he expected.

At four o'clock in the afternoon, Zhang Wen was taken to Interrogation Room No. 2 of Furong Police Station.

Zhang Wen, who looked innocent, couldn't help but feel his heart skip a beat when he looked at Gu Chen, Officer Wang and Lu Weiwei.

He looked at Gu Chen and said, "Aren't you Mr. John Lauer's VIP guest at the concert? I've seen you before."

"I've seen you too." Gu Chen said.

Zhang Wen looked at the surrounding environment and couldn't help but chuckle a few times: "I wonder what the police comrades need to know when they called me here? Have I committed a crime?"

"Zhang Wen, can you explain Zhao Mingming's situation?" Lu Weiwei on the other side also asked.

In fact, after everyone learned the truth, no matter how innocent Zhang Wen pretended, everyone actually knew it in their hearts.

Looking at this situation, it feels like watching a monkey show.

"Zhao Mingming?" Zhang Wen looked stunned and said, "He's not dead yet? I heard he was seriously injured?"

"Do you really want him to die?" Gu Chen asked with a frown.

Zhang Wen sneered twice and leaned back in his seat: "What does it have to do with me whether he dies or not? My relationship with him is not good anyway."

"Both of you are Wang Dewen's students, right?" Gu Chen quickly wrote the records of the scene in the notebook in his hand.

"That's right." Zhang Wen looked up at the ceiling and said, "But now I'm just Teacher Wang's assistant, and he, Zhao Mingming, is Teacher Wang's favorite student."

"Are you very unconvinced?" Gu Chen raised his head, looked at Zhang Wen and said: "As far as I know, your piano level is far superior to Zhao Mingming, so why is the guest of John Lauer's special concert on the stage this time?

But it’s Zhao Mingming?”

Seeing that Zhang Wen's expression was suddenly startled and obviously tightened, Gu Chen continued: "He Zhao Mingming made a few obvious mistakes on the stage, which shows that his piano skills are indeed not solid enough, but if it were you,

It could be a lot better.”

"Don't mention him to me." Zhang Wen's expression suddenly became serious, and he turned pale as he said: "In addition to having a good father, what else does Zhao Mingming have? His piano skills are only so-so, I'm fooling you.

These laymen may be OK, but when my colleagues listen to his performance, it is simply rubbish, rubbish that insults the ears."

Zhang Wen's extreme degree is somewhat beyond everyone's expectations.

After being silent for a few seconds, Officer Wang said, "It seems that you and Zhao Mingming don't have a harmonious relationship?"

"Isn't it?" Zhang Wen also said with a cold face, "In Teacher Wang's studio, this is something everyone knows. He, Zhao Mingming, is used to being arrogant, and his nostrils are turned upward when he sees everyone.

Many people don't like him because of his appearance."

"But he took away the performance opportunity that was supposed to be yours. Do you know this?" Gu Chen asked.

"You know." Zhang Wen lowered his head with a melancholy look on his face: "Who doesn't know that I am the best pianist under Teacher Wang? Who is Zhao Mingming? If it weren't for his father's crazy sponsorship of activities, wouldn't he?

He is not qualified to perform at the Jiangnan Grand Theater or any ordinary Shangqing performance."

"But even so, this guy still looks so arrogant. He is afraid that no one will know that he is Zhao Mingming. I hate him very much, and everyone else in the studio also hates him."

"But why did you want to kill him?" Gu Chen suddenly asked, making Zhang Wen stunned on the spot.

He looked at Gu Chen with eyes as if he had been struck to the soul.

"Let me ask you, why did you kill him?" Gu Chen paused and said, "Just because he attended John Lauer's concert instead of you, so you want to kill him?"

"Comrade police, what are you talking about? Why can't I understand you?" Zhang Wen was confused.

He indeed hated Zhao Mingming deeply and had made many preparations in advance, but he was always cautious.

But facing Gu Chen, it was as if this guy could sense what he was thinking in his heart.

"Don't admit it?" This was not the first time Lu Weiwei had done this kind of work. She imitated Officer Wang's usual dignity in interrogating prisoners and slapped the table hard!

"boom!"

Zhang Wen was startled.

"What is this?" Lu Weiwei walked up to Zhang Wen with a photo of a blue gas bottle in her hand and placed it on his table: "You should know this, right?"

Zhang Wen now understood why the police summoned him, so he smiled bitterly at Lu Weiwei and said, "Comrade police, why are you showing me this?"

Zhang Wen certainly knew about the blue gas bottle in the picture.

However, I had prepared so much and had already thrown the blue gas bottle into a trash can in a blind spot.

To be precise, he had destroyed the evidence. How did the police find the blue gas bottle that was supposed to disappear?

"You're pretending to be pretty good." Lu Weiwei couldn't help curling her lips and said lightly: "This is the gas you filled the vehicle with last night. Did you forget it so quickly?"

"What kind of gas? I have no idea what you are talking about." Zhang Wen retracted his disdain and sat quietly on his seat with an indifferent expression.

"You don't have to worry about whether it's the bottle you used yesterday. Let's wait for the fingerprint detection." Officer Wang took a sip of wolfberry tea and couldn't help but let out a pleasant "ha".

Gu Chen also said: "You used toxic gas to inject air into the left front tire of the car, which caused the normal left front tire to have an obviously excessive tire pressure. Then Zhao Mingming, who took over for you to drive, noticed the excessive tire pressure alarm, so

Get out of the car and release the gas, and the poisonous gas you added will instantly spread into the surrounding air."

"And it was Zhao Mingming who inhaled the poisonous gas you injected, which caused him to foam at the mouth and become confused while driving, which ultimately led to last night's car accident. What else can you explain?"

Zhang Wen was completely stunned and didn't speak for a long time.

"If these are not enough, we also have detailed investigation records here, you can take a look for yourself." Officer Wang handed the information to Gu Chen, and Gu Chen walked up to Zhang Wen and handed the information into his hands.

"This... this is not true." Zhang Wen just looked at it briefly and immediately showed extremely complicated emotions: "This is definitely not true. I did not harm Zhao Mingming, no."

"It doesn't matter whether it's there or not." Gu Chen took off the pin on the document and threw one of the documents with pictures and text in front of him: "This is when you drive the vehicle to a remote repair shop and the shop owner explains

Oral transcript.”

Then another piece of information and text was thrown over: "This is a blue gas bottle, a test report of gas component residues."

Looking at Zhang Wen's distracted eyes, Gu Chen threw several documents over one after another: "This is the test report that you deliberately increased the tire pressure. This is the information on how Zhao Mingming deflated the tires. This is..."

Gu Chen threw all the evidence in front of Zhang Wen one by one.

At this moment, Zhang Wen's eyes were expressionless as he stared blankly at the evidence in front of him.
