"Brother Tang, have you eaten?"

"Not yet, if such a thing happened, how could I feel like eating?" Tang Jin said angrily, "I'm going to be called over and scolded again tomorrow morning."

"Let's go, let's find a place to have a meal first. Only after we have the strength to solve the case." Lu Xiyan greeted.

"Qi Huan, I'm leaving. This is not your own business, and you can't resist..."

"Why would you ask Deshun Pavilion to send it here? Now, I'm afraid there will be no seat for a long time?" Qi Huan suggested.

"Your suggestion is pretty good. I'll call them and ask them to deliver it quickly." Tang Jin slapped the table and agreed.

"Since you all think this is good, I don't object." Lu Xiyan laughed, "Old Qi, come and accompany me to see the death scene."

"So what can I see?"

"Let's go, I'll have to wait for a while anyway." Lu Xiyan pulled Qi Huan up directly from the sofa and went to the detention room of the Political Department.

" Room No. 3 is Ahui's cell. After the accident, no one came in except to remove the body." Qi Huan pointed to the cell No. 3 and introduced to Lu Xiyan.

The environment in the detention room is slightly better than that in the detention center, but it is also very cold. The ventilation vents lead directly to the outside, and it may be better in summer. It is the cold winter month now, and the cold wind blows in. If you stand at the vent, your face will hurt like a knife.

A simple wooden bed with hay, a straw mat and a quilt, spreading on the bed in a mess, exuding a musty smell.

The figure of a person lying on the ground was drawn with chalk.

This is the shape of Ah Hui when he died. He looked like he was sitting on the ground, then lying on his side, and then head down.

"Old Qi, if you take poison alone and commit suicide, then what will he do before committing suicide?"

"If he had something to say, he would definitely give his last words."

"Well, this is one of them, what else?"

"Unless it is a sudden death, everyone who wants to die wants to make himself more decent and suffer less in the end." Qi Huan thought for a moment, and then said.

"Yes, people who commit suicide usually have various reasons. To put it in a nutshell, they are despair of reality. However, there are two types of people who are desperate. One is that their hearts are ashamed, they have no desire to live, and they want to die. It doesn't matter how they die. Even if they are wild corpses and wild dogs, they don't care about eating them. There is another difference. He knows that he will die without a doubt, but he is firm in his heart and feels that he has died as much as possible. Even if he dies, he will die decently, rather than just die casually." Lu Xiyan analyzed.

"What do you mean is this Ah Hui belongs to?"

"He hasn't reached the point of complete despair yet, so why do he want to die? Even if he really reaches that point, he will commit suicide by taking poison according to the logic of normal people's behavior, and he will lie on the bed and leave quietly."

"Maybe it was the poison attack, the pain was unbearable, falling out of the bed?"

"There will inevitably be a lot of noise, so why can't the guards outside find out? So, from this scene, we can tell that it was he who killed him." Lu Xiyan said.

"Advisor Lu Gao Jian, the inspector general took a look at the scene and suspected that he was killing him. But if he said so, the person who poisoned and killed people must be a member of the Political Department. Therefore, the inspector general pretended to say that it was suicide to calm people's hearts."

"Brother Tang's move is very clever. He can calm the person who was secretly poisoned, and then secretly verify it and find out the inner ghost." Lu Xiyan nodded.

"That's right, the Inspector General is one of the people I respect the most." Qi Huan smiled, "Of course, I admire you, Consultant Lu, too."

"Don't praise me." Lu Xiyan squatted down and carefully observed the traces of Ah Hui lying on the ground.

“Are there any flashlights?”

"Yes, I'll get one for you." Qi Huan said.

The flashlight was quickly taken over. Lu Xiyan turned on the switch and a beam of light shot out directly, which was much brighter than the electric lights in the cell room.

"Old Qi, has Ah Hui finished supper?"

"Most of the food was eaten, and the remaining half was placed on the small table without moving." Qi Huan pointed to the small table in the corner and said.

"Are the chopsticks and the remaining food in a mess?"

"No, the leftovers are arranged normally, and they should not be able to eat them. After all, the food here is not as good as those outside. Ah Hui usually eats and wears well, so he should have never suffered such hardships." Qi Huan said.

"That person still bears your punishment, right?"

Qi Huan smiled awkwardly.

"You guys have tried one, has he confessed?"

"No, but I admit that I received a call at night, but he said that the man called the wrong one. He even scolded the other party for being crazy and then hung up." Qi Huan said.

"There is no evidence of death." Lu Xiyan exclaimed.

"Old Qi, are you smoking?" Lu Xiyan suddenly sniffed his nose and asked Qi Huan.

"Go, Consultant Lu, don't you know, why did you suddenly ask about this?" Qi Huan asked with confusion.

"Do you remember how Weng Xiong died?"

"Isn't that Tian Sen poisoned him to death?" Qi Huan's expression changed slightly as soon as he said.

"Old Qi, please smell it carefully. Does this cell have the smell of tobacco burning? Although it is very light, it has not completely dissipated." Lu Xiyan said.

"Consultant Lu, you might be saying that the person who killed Ah Hui was Tian Sen. He had already been removed from the police station and sent him away."

"How many people in the Political Department know about Tian Sen's murder?"

"There are few people who know about it and have been banned, and Weng Xiong died in a safe house. This matter is not allowed to be discussed in the Political Department." Qi Huan said.

"Old Qi, look, what is this?" Lu Xiyan found a cigarette butt from the corner under the bed.

"Cigarette butt?" Qi Huan was stunned.

"Who else has been to the detention room after Shui Sheng delivers the meal?"

"No, there are guards at the door of the detention room. If someone comes in, they will definitely know." Qi Huan said with great certainty.

"Did you smoke a cigarette for Ah Hui during the afternoon interrogation?"

"Ah Hui is an addict. He seems to ask me for a cigarette once, but I didn't give it to him, so he wanted to force him to confess. Later, the inspector Cheng Haitao, who participated in the interrogation, gave him one, but he smoked it on the spot, and the cigarette butt should have been thrown in the interrogation room." Qi Huan said.

"Later, no one gave him cigarettes?" Lu Xiyan asked.

"I didn't know later, I didn't give it to you anyway." Qi Huan said.

"Are all the people participating in the interrogation still there?"

"exist."

“Go and ask.”

"Okay!" Qi Huan agreed and quickly walked out.

If no one gave Ah Hui cigarettes, where did the cigarette butt in the cell come from? Left by the previous prisoner, or was it another murder with poison in tobacco?

Weng Xiong is an addict, and Ah Hui seems to be the same. It is not surprising that some people think of the same way to kill people.

He took out a bag of evidence, Lu Xiyan put the cigarette butt in and put it in his pocket.

Lu Xiyan noticed the ventilation opening in the cell.

The vent is very small, and it is designed to be small outside and inside. From the inside, it cannot accommodate an adult. The more you go out, the tighter the hole, and it is almost impossible to escape through the vent.

However, if someone is outside the vent, he can talk to the person inside smoothly.

“Huh?”

Lu Xiyan suddenly realized something was wrong. There seemed to be something wrong with the position of the wooden bed. He stood up with his foot, and his head just touched the position of the vent.

He didn't know Ah Hui's height, but he was generally not much shorter than he was on his own.

Getting off the wooden bed, carefully observing the traces of friction on the ground, he found the traces of moving the wooden bed.

"Consultant Lu, I asked, but no one gave it to you later..." Qi Huan came in from outside and saw Lu Xiyan standing on the bed. He asked in surprise, "Consultant Lu, are you?"

"The location of this bed was not originally here, but was moved by people. Moreover, standing on the bed, people can fully enjoy the position of the vent." Lu Xiyan said.

“You mean, someone is passing through the vent…”

"Leave this cigarette butt to the forensic department for testing to see if there is any gain." Lu Xiyan got off the bed, took out the evidence bag from his bag and handed it to Qi Huan, "Although the traces on the ground were deliberately rubbed off, they can still be seen."

"Okay, I'll go now." Qi Huan turned around, "By the way, the inspector general asked me to call you over for dinner. It's cold this day, and the food will be not delicious if it's cold.

"Okay, I'll go now." Lu Xiyan nodded.

It can basically be determined that he killed it, but it is hard to say how this poison was sent to Ah Hui's mouth, after all, the food test results have not yet come out.

There were many suspicious points at the scene of the death, especially the cigarette butt, which made Lu Xiyan involuntarily remember the case of Weng Xiong being poisoned.

...

The small conference room on the third floor has temporarily become a restaurant.

"Old Lu, come on, I want to have a drink to warm up my body. I'll call you here this night. I don't know how unhappy my brother and sister are." Tang Jin poured wine for Lu Xiyan and said.

"Brother Tang, please be polite."

"You and Qi Huan went to the cell, what did you find?" Tang Jin sat down and asked.

"It can be basically confirmed that he killed it, but how did this poison get into Ah Hui's mouth? I still have to wait for the poison detection report to come out." Lu Xiyan said, "Actually, Brother Tang, you have discovered it long ago?"

"This is not the first time that an insider has appeared in the department, it's embarrassing." Tang Jin sighed.

"Brother Tang, the forest is big, and there are all kinds of birds. You can't control this thing that is separated from the belly of human heart." Lu Xiyan smiled.

If Tang Jin had run the Political Department into a one-man show, the French would probably not be able to sleep.

There is nothing wrong with the political process. Let the French grasp it. This is actually a balanced art.

"Eat, eat, I heard you plan to invite students to dinner in the evening, but I called me and I should apologize and punish him!" Tang Jin stood up, picked up the wine glass and punished himself three times in one breath.

"Inspector General, Consultant Lu, no poison was detected in the food Ah Hui ate. The suspicion of Lao Liu and Shui Sheng was initially ruled out. I asked their master and apprentice to go back first, but accept the summons at any time." Qi Huan came in from outside the door.

"Come on, Lao Qi, sit down and have a meal, you'll be the one who's left." Lu Xiyan greeted.

"Okay, I'm so hungry that I'm pressing my heart against my back."
