The family doctor only heard an angry shout from the big man, and several strong men rushed to him and pressed him to the ground. This made him terrified and shouted for help with all his strength.

Unfortunately, just after shouting a few words, a smelly sock blocked his mouth, and the shouting stopped abruptly. The man kept twisting his body trying to break free from the control of these lawless people.

Zuo Zhong folded his arms and looked down at the other party's reaction, slightly disappointed. If the doctor had poisoned the potion and the crime was suddenly revealed, he would be dominated by panic.

But this man's face was full of confusion, and there was a trace of anger in his eyes. There was nothing wrong with him. Of course, this still did not prove that there was no problem with the doctor's identity.

If the other party is a Japanese intelligence officer, he is fully capable of adjusting his emotions in a short period of time. What is certain now is that the doctor is either innocent or has received professional intelligence training.

Next, we just need to conduct a corresponding background investigation to confirm whether there is anything suspicious about the doctor's identity. If not, the other party's suspicion of murder will be low, and the confession will be credible.

On the contrary, it is even simpler. Two new electric chairs were installed in the interrogation room of the Secret Service last year, which can adjust multi-level current and voltage, ensuring that prisoners who have experienced it will feel at home and will never forget it.

But that's the last option.

Can't be used easily.

Case detection is a process of constant determination and elimination. Especially in highly sensitive cases, it is best to use words and probing methods to eliminate interfering factors and avoid unnecessary complications.

"Okay, let him go."

Zuo Zhong thought of a lot in his mind in an instant. He raised his head and gave instructions to his subordinates. He then looked at the family doctor with a smile: "Oh, Mr. Wang was just joking. I believe you won't mind."

Since his trip to Germany, he found that the name of the dead ghost king Aofu was very useful, so he decided to use this pseudonym from now on. The best thing is that he is not afraid of people's investigation, and a dead intelligence officer is even more mysterious.

Now that the agents had loosened their restraints, the family doctor quickly threw the smelly socks out of his mouth, got up in a hurry, pointed at Zuo Zhong angrily, and said while trembling all over.

"I'm going to the government to accuse you. Why do you treat me like this? Ugh~ I am a witness in the case, not a suspect. There will always be a place for reasoning in Jinling, even if it is the police station..."

"Wait, you said we are the police? Who told you, me or them? Sorry, if that's the case, then we may have to pause for a while. I want to deal with this matter first."

Zuo Zhong laughed and looked at his subordinates. The agents quickly shook their heads. According to confidentiality rules, after contacting the target, no one was allowed to speak to each other except for necessary exchanges.

When the family doctor heard this, Ye was stunned and asked involuntarily: "Then who are you? No one has the right to restrict my freedom except the police station. Please get out of the way. I want to go home."

"Haha, don't worry."

Zuo Zhong sat down on the Grand Master's chair and played with his fingers: "My name is Wang Aofu, from the Second Division of the Investigation and Statistics Bureau of the Military Commission. To change my name to something you can understand, it's the Secret Service.

Lu Yongyi should have mentioned to us that ordinary cases do not require the Secret Service to come forward, so if you have anything to say, just say it quickly, and don’t wait until you have been tortured in the interrogation room before you speak."

The family doctor's heart suddenly shrank when he heard the words "Secret Service". His original anger immediately disappeared. His whole body was like a deflated balloon, and he didn't know where to put his nervous hands and feet.

Zuo Zhong noticed the other party's uneasiness, smiled and teased: "I still like your unruly look just now. Since you know, let's not waste each other's time. Let's talk.

I want to know everything about Dean Lu's death. Also, you insist that he died of a heart attack. What is your basis? If you can't tell, please come back to the Secret Service with us to talk."

He asked a question with a smile, then took a document from the hand of the little agent next to him, opened it and saw that it contained the household registration information of the family doctor in the police station, which was recorded in great detail.

No matter what the other party said, he was the personal doctor of the former Zhejiang Provincial Chairman. His background must have been screened. If the underground party got into the core organization of the bald lair, everyone would suffer.

Zuo Zhong glanced at the file. His name was Deng Xuegang, a native of Hunan Province. He was from the same hometown as Lu Yong'an. He was 35 years old. He graduated from Xiangya Medical College and went to study in the UK in the 14th year of the Republic of China.

After returning to China, he has been working as Lu Yong'an's doctor. His family relationship is relatively simple. His parents are still alive, and his wife and only son live in his hometown. His life trajectory is normal and he has not been impostored.

But will the other party be recruited by the Japanese intelligence agency while studying abroad? This requires overseas investigation and questioning of Deng Xuegang’s classmates and teachers when he was studying in the UK to look for relevant clues.

Zuo Zhong was leisurely looking at the household registration information here. The principal, Deng Xuegang, was no longer so calm after hearing the question, and hurriedly explained that Lu Yong'an's physical reaction at that time was a standard symptom of death from a heart attack.

"Sir, as soon as I entered, I saw that Dean Lu's skin became moist and cold, his face turned pale, his lips turned blue and purple, his blood pressure dropped after measurement, his heart sounds became low and weak, and his pulse was fast and weak.

At the same time, breathing gradually weakened, and the two states of respiratory cessation and respiratory intensification alternated, showing a tidal pattern over and over again, and breathing patterns such as double inhalation, sighing, and nodding appeared.

I gave him digitalis medicine, but as a result, Dean Lu’s pores expanded, various reflexes gradually disappeared, muscle tone was lost, and he stopped breathing in just a few minutes, and finally his heart stopped.”

Digitalis?

Zuo Zhong's eyes widened. Ling Sanping said that this was the best drug to create the illusion of death from heart disease in patients with cerebral congestion, because the pathological manifestations of the two were very similar. Deng Xuegang must have known this.

Now that he knew it, it would be strange to give such a dangerous drug to his patients. Wasn't he afraid that he would not be able to tell whether the patient had a recurrence of cerebral congestion or whether the patient had taken too much digitalis?

Zuo Zhong, who felt that he had caught a slight flaw, turned cold and asked the other party in a deep voice why he didn't use glycerol tablets (not a typo) or aspirin to treat Lu Yong'an's sudden heart attack.

Deng Xuegang did not expect that this agent actually knew some medical knowledge. He hesitated and explained that the deceased was usually greedy for food, especially fatty meat, and suffered from frequent constipation.

In this case, glycerin can only be used to help defecation, so Lu Yong'an was quite repulsive to the glycerin tablets containing the word "glycerin" and was unwilling to take them at all. This was probably a big shot's willfulness.

The reason for not using aspirin is even simpler. The deceased had drunk alcohol at noon. Aspirin should not be taken at the same time as alcohol. The side effects will aggravate the pain throughout the body and cause liver damage.

A very reasonable explanation, but a bit far-fetched.

Zuo Zhong didn't know if Lu Yong'an really refused to take glycerin tablets, but this kind of lie could be easily proven. He only needed to ask Mrs. Ding, and the other party couldn't hide it at all.

After pondering for a while, he continued to ask: "According to our investigation of the scene, we found that Dean Lu struggled before his death and had enough time to leave his last words. You'd better explain it honestly.

Let me tell you the truth, the implications of this case are so extensive that it has reached the heavens, and the chairman of the committee has personally given instructions. Once we find out that you are talking nonsense, you will end up in a disastrous end, do you understand?"

"this..."

Deng Xuegang looked embarrassed, as if he had something to hide. When the agents around him saw this, they all made fierce expressions. This frightened the doctor so much that he turned pale and hurriedly told the inside story.

"It's not that Mr. Zheng deliberately concealed it, but it actually harmed Dean Lu's reputation. I heard Mrs. Ru's call for help and went downstairs. When I entered the door, I found that their clothes were a bit... They must have just had sex.

During the emergency treatment, Dean Lu told me many times with difficulty that he must not spread the news that he had a heart attack caused by Ma Shangfeng, otherwise the eldest son would definitely be laughed at by his classmates in school.

As the saying goes, cannibalism is a reward for being loyal to others. I encountered difficulties when I just returned to my country. I relied on Dean Lu to help me get through the difficulties. I also asked the chief to preserve the last bit of dignity for the deceased. Please give me my thanks, Zheng."

After saying that, he bowed to Zuo Zhong and begged Zuo Zhong to keep it secret. Zuo Zhong's face darkened. Damn it, Lu Yong'an is very good at playing. People are old and the heart is not old. The problem is that he has slept on that big bed before.

But this matter is not important. What is important is that this is just a statement made by Deng Xuegang's family. Whether it is true or false cannot be judged. The two participants in the incident are both dead, so we can't go to the underworld to investigate.

Obviously, before new clues and new evidence appear, the other party has no value in asking. Staying here will only waste time. It is better to go to Baiziting to ask Mrs. Ding about glycerin.

Zuo Zhong made up his mind, closed his household registration file, stood up, and called the special agents who came to the safe house to give him some instructions, asking them to protect the target and not leave without permission.

Then he ignored the anxious Deng Xuegang, went out and led the guards back to Baizi Pavilion. After asking Mrs. Ding, he got an affirmative answer that Lu Yong'an really did not want to use glycerin tablets.

Moreover, not only Mrs. Ding knew about this, but other people in the Lu family also knew about it. Zuo Zhong felt uneasy and found a few servants and bodyguards. After some coercion and inducement, he got the same answer.

At this point the clue was interrupted.

Do we really need to rely on autopsy?

Forensic medicine is indeed an indispensable part of the investigation process, but you should not rely too much on it. The dead cannot lie, but they can give wrong or even opposite clues under the arrangement of others.

Zuo Zhong stood at the scene of Lu Yong'an's death without saying a word, looking out the window at the slowly setting sun. Half of his face was filled with the afterglow of the setting sun, and half was dim. After a long time, he left the room.

He came to Gu Qi and whispered a few words, and nodded in the eyes of the other party's doubts. Although some methods were not authentic, if he wanted to find out the truth about Lu Yong'an's death, he could only use dangerous tactics.

late at night.
