"Sympathy, Cheng Haitao, do you think I'm stupid?" Tang Jin was furious. It would be fine if he made small reports, but he couldn't shake his status at all. He didn't care.

This kind of villain also has the function of a villain. At least it can block open and hidden arrows, and remind yourself at all times not to be too obsessed.

However, he actually said that he gave Ah Hui a cigarette because of "sympathy".

Is sympathetic to a killer accomplice still the position a policeman should have?

"Inspector General, everyone outside calls Sun Yanan a righteous man and a hero. I am also a Chinese. I also think he is right. Shouldn't a traitor be killed?" Cheng Haitao sneered.

"Is Consultant Lu a traitor?"

"It's not what I said, what are you asking me for?" Cheng Haitao avoided the question and said, "I just gave two cigarettes. Even if there is something in the cigarette, that thing can't kill anyone, right?"

"During the interrogation, you gave him one, everyone saw this. When did you give the second one?" Tang Jin asked.

"When the suspect was escorted back to the cell, he took care of me and asked me for one, and I gave it to him, and lit it." Cheng Haitao said calmly.

"Who saw it?"

"Then I don't know. I stayed at the door of cell No. 3 for a while, and then left. When Bushuisheng delivered food to him, he was still fine, right?" Cheng Haitao said.

"Inspector General, when Shui Sheng delivers food, the people are indeed good, there is no problem." Qi Huan said to Tang Jin.

"He Inspector General, I just gave the suspect two cigarettes with materials. You will treat me as a prisoner and interrogate me. I will go to the director to accuse you." Cheng Haitao said angrily.

"You can sue me, but the cigarette you gave to the prisoner was mixed with white face. As a police officer, you know what this is. "Tang Jin sneered. He was not afraid of complaining.

"Tang Jin, can I leave now?" Cheng Haitao stood up with anger and asked.

Tang Jin nodded. Although Cheng Haitao did something a little beyond the line, there was no evidence that he had a necessary connection with Ah Hui's death.

He is also a police officer in the judicial arrest room, and he cannot be detained without evidence.

"You can leave, but you can't leave the French Concession in the near future."

"snort!"

"Inspector General, Cheng Haitao has something wrong. Judging from his arrogant look, how could he take you seriously?" Qi Huan looked at Cheng Haitao's leaving back with dissatisfaction.

"Don't say that. If you are suspected, you will feel uncomfortable and get angry." Tang Jin said, "He is understandable."

"We really want to rule out Cheng Haitao's suspicion?"

"A Hui is highly toxic to potassium cyanide. Cheng Haitao only gave A Hui two cigarettes with materials, and no potassium cyanide was detected in it. How did it prove that it was related to A Hui's death?" Tang Jin asked back.

"Oh, I'll have a waste of work..." Qi Huan sighed, thinking that there was a breakthrough, but who knew that it would have been a waste of work.

"It's not a waste of work. Someone is in a hurry to kill Ah Hui. This means that Ah Hui will have a fatal threat to someone when he is alive. Qi Huan, who do you think this person will be?" Tang Jin said with a leisurely voice, and a strange smile appeared on the corner of his mouth.

"Sun Yanan!"

"That's right, this Ah Hui should be Sun Yanan's confidant. I'm afraid that many secrets are known, and some people don't want us to know these secrets, so..."

"Have you investigated Ah Hui's whereabouts the morning before yesterday?"

"I checked it. According to other folks in the watch shop, Ah Hui went out that day as soon as the door opened and didn't come back until noon." Qi Huan said, "But no one knows where he went and what he did."

"Which day did Lao Lu get assassinated?"

"The time has passed a little long, and they can't remember it very clearly. However, Ah Hui usually looks at the store at night and helps in the store. He rarely goes out. If he goes out, he just buys some daily necessities or something." Qi Huan said, "And Ah Hui is usually silent and has no friends."

"Then how did he get addicted to drugs?"

"Oh, this is related to his suffering from rheumatism. In order to relieve pain, he accidentally took red pills and suffered this problem." Qi Huan explained.

Tang Jin nodded. Red Pills are a drug that does relieve pain, but they are easy to get addicted.

"Almost most of this Ah Hui's salary in the watch shop is to buy red pills. After getting this problem, he doesn't like to communicate and talk to others."

"How long has this Ah Hui been addicted to drugs?" The half-closed office was pushed away, and Lu Xiyan walked in from outside and asked.

"Consultant Lu, why are you here?"

"In the afternoon, Yuan Rui came to me and asked some questions about Ahui's autopsy. He told me that Ahui's stomach dissolved substances contained a large amount of morphine, but the concentration of morphine in the blood was not high. Therefore, I analyzed and inferred that when Ahui died, it was very likely that he would swallow morphine and potassium cyanide together." Lu Xiyan explained.

"How is this possible if morphine is swallowed with potassium cyanide?"

"There is nothing impossible. Qi Huan mentioned Red Pill just now, which made me guess a possibility. He interrupted your conversation without knocking on the door." Lu Xiyan said.

"What's the possibility?" Tang Jin and Qi Huan looked at each other and asked in unison.

"The ingredients of red pills are morphine and brown sugar. If potassium cyanide is put into the red pill, it will be a poison. If it is bitten, it will be fatal in an instant. It will be swallowed into the stomach, and the stomach juice melts, and it will eventually be destroyed and dies." Lu Xiyan explained.

"In other words, red pills will not die immediately after being swallowed by swallowing potassium cyanide. It may take a while to die of poisoning?" Tang Jin suddenly grasped the point.

"Yes, in theory, the death time can be controlled, but it is unknown how long it is." Lu Xiyan said, "This needs to be done to verify it."

"After saying this, the range of poisoned people will be wider." Tang Jin frowned slightly.

"From the comparison of the concentration of morphine in the stomach and blood, the maximum from eating to death from poisoning is no more than an hour. Therefore, if someone poisons it, the poisoned person must have been in contact with it within an hour before Ah Hui died." Lu Xiyan said.

"One hour before death, the range is much smaller. I'll go and investigate immediately." Qi Huan waved his hand excitedly and narrowed the scope of the investigation. This was a major discovery.

"Qi Huan, wait a moment."

"Inspector General?" Qi Huan said in confusion.

"Brother Tang means that the investigation should not be too loud, and it should be carried out quietly to avoid alarming the poisoned person?" Lu Xiyan said.

"Old Lu knows my feelings." Tang Jin smiled slightly.

"Inspector General, I understand." Qi Huan nodded.

"Brother Tang, you and I know who Ah Hui's death is beneficial to you. This case is probably more complicated than we imagined." When Qi Huan went out, Lu Xiyan walked over and closed the door, and then came back and solemnly told Tang Jin.

"Hey, do you know? I received the order from Boss Dai early this morning, asking us to cooperate as much as possible to rescue Sun Yanan." Tang Jin sighed.

"Why?" Lu Xiyan asked in surprise.

"Maybe it is because of Sun Yanan's contributions to the traitors in the past. Such people are heroes in the Military Control Commission, and it is also appropriate for the Military Control Commission to try its best to rescue them." Tang Jin said.

"Then what are you going to do with Brother Tang?"

"The order I received was just to cooperate with the rescue. As for how to rescue and what the rescue plan was, I don't know now." Tang Jin said.

"This is really strange. Why didn't Boss Dai order a rescue before? Why did he suddenly order a rescue now?" Lu Xiyan asked.

"I don't know that Boss Dai will not explain too much to his subordinates when doing things. Since he has given an order, he will ask his subordinates to complete it perfectly." Tang Jin said.

"What is your attitude towards this?"

"I dare not disobey Boss Dai's orders, but there are many doubts about Sun Yanan. It would be a pity if he let it go." Tang Jin said.

"Didn't you report Sun Yanan's suspicion to Boss Dai?"

"Of course I reported it, but Boss Dai doesn't seem to think there is anything wrong with these doubts." Tang Jin said helplessly.

"Can Boss Dai need to hire people and fall in love with Sun Yanan?"

"It's unlikely that Sun Yanan has been handed over to us twice. What ability does he have to be attracted to by Boss Dai?" Tang Jin shook his head and said, "There are many experts in the Military Control Commission, and there are many who are better than him. Can't you pick someone better than him?"

"That's right, then that's strange. Why does Boss Dai attach so much importance to Sun Yanan and personally order us to cooperate in the rescue?"

"I don't know, a headache..."

"Ah Hui is dead, Sun Yanan is the only clue in our hands. Since Boss Dai ordered, Brother Tang, we don't have to worry about it, just execute the order." Lu Xiyan said.

"Lao Lu, don't you mind?"

"What do I mind? Although Sun Yanan tried to kill me again and again, he didn't do anything to me. Besides, he was also a misunderstanding of me and acted. If I insisted on holding on, wouldn't it hurt the relatives and the enemy would be quick?" Lu Xiyan said with a smile.

"Old Lu is very wise and I admire you."

"You and I actually want to know the truth of the matter, don't say so noble." Lu Xiyan and Tang Jin smiled at each other, and everything was silent.

...

"What did you say? Dai Yunong ordered Tang Jin to cooperate in rescuing Sun Yanan?" Lu Xiyan came out of the law arresting room and made an appointment with Hu Yunzhi.

They are now partners, and it will not be too eye-catching to meet and have a cup of tea.

"I can't figure out what Dai Yunong means, depending on the situation, Tang Jin doesn't know why. Where did Sun Yanan be attracted by Dai Li?" Lu Xiyan was very surprised.

"Can it be Sun Yanan's ability to act?"

"Ru Yun, the master in the Military Control Commission, is there anyone missing?" Lu Xiyan gave Hu Yun's eyes a blank.

"That's what's special about him, it doesn't seem to be obvious, haha." Hu Yunzhi then smiled embarrassedly.

"I thought of it, but I don't know if it's right." Lu Xiyan suddenly had a flash of inspiration in his mind.

"What?"

"In the previous materials about Sun Yanan, it was not mentioned that he had joined the Iron Blood Anti-Traitor Group, which means that Sun Yanan did not have any mastery of this historical period."

"What do you mean is that Dai Yunnong now knows his history and wants to use him to re-inject the Iron Blood Anti-Traitor Group?" Hu Yunzhi deserves to be an intelligence worker for many years, and he hits the nail on the head.

"It's not that there is no such possibility!" Lu Xiyan nodded. He thought of this guess not long after. If it weren't for Dai Yunong's rescue order, he wouldn't have thought of it.

"Tang Jin cooperated with the Iron Blood Anti-Traitor Group and had a close relationship. Dai Yunnong naturally could not tell him this secret. Dai was suspicious and he would not easily believe his subordinates." Hu Yunzhi analyzed.

"Well, Lao Hu, you are good at analytical skills!" Lu Xiyan smiled and the corners of his mouth rose slightly.

"But, he rescued the person, how could he get into the Iron Blood Anti-Traitor Group?" Hu Yunzhi asked back.
