Su Cheng said: "Xu Xuan has an interesting idea. She said that someone might hire Liu Yan to steal things that Qin's father was shameless. At that time, I refuted that if this is the case, why did you have to be undercover in TTT for so long? Qin's father's family has poor security. After thinking about it, I think it's quite possible. It's necessary to change a little. What Liu Yan is going to steal is Qin's family's things, not Qin's father's things."

"Oh? You mean that Liu Yan was the one who started the battle with Mr. Qin at the beginning. She didn't find anything at Qin Shao's company. After entering Qin Shao's villa last night, she also touched Qin's father's villa?"

Su Cheng said: "As Liu Yan is an undercover ttt, I think Liu Yan has a helper. It is very likely that the helper killed her. Liu Yan went to Qin's father's study. I think the helper suspected that Qin's father had something they wanted in his study, or that they had come, so just steal it once. If you speculate so, the helper or their boss must know Qin's father and have a good relationship with Qin's father, so you can at least enter the study."

"Boss Liu Yan thinks Qin's father's study is worth investigating." Zuo Luo nodded slowly: "This speculation is more logical. It is possible that Liu Yan has obtained something, right?"

"This is not clear. We don't know what the thing is. It may be that the phone takes a photo, deletes, etc., which may have been transferred to the helper. The study window is only three meters away from the back wall. I searched Liu Yan for her body and found no stolen goods."

"It may be the helper or the boss who killed Liu Yan to silence him. It may be the black hand of Mr. Qin. Liu Yan knows too much."

"There is a possibility, which is in line with Mr. Qin's sentiment of passive cooperation with the investigation last night."

Zuo Luo said: "We don't care about the motives for now. We will find a way to dig out the murderer first. To be honest, now there are cases now, I am the first to think of hanged ghosts. Hanging ghosts commit crimes, and they are tied up one by one. It is difficult to follow the clues. If you don't look like a gang of hanged ghosts, it should be fine to catch a murderer, right?"

This sentence is a question. Zuo Luo knew that if he wanted to solve such a case and was quick, Su Cheng's performance was the key. But judging from Su Cheng's expression, he might not have slept for a few hours last night.

Su Cheng was not in a hurry: "First look at the situation, we can't determine the surname of the case at present... By the way, I have always wanted to ask a question, but I think it's a bit inappropriate..."

"If it's not suitable, don't ask." Zuo Luo replied.

"..." Su Cheng was angry: "I just want to ask."

"Why do you talk so much nonsense? Ask." He whispered.

"..." Su Cheng said to himself in his heart, he is well-educated, gentlemanly, and educated. Don't bother with him. Remember, you can't beat him. Su Cheng took a deep breath and asked: "It has been about eleven months since I arrived in the Z department. The Falcon team has only conducted field missions once, but it is because Blue River and Hurricane team have just returned from the police."

Zuo Luo drove silently and said for a long time: "Blue River and Hurricane have three generals, the leaders of the three teams, commonly known as the small supervisor. Although they work differently, they have a very private relationship with each other."

"Then what?"

"Only speaking, what should I say? The first reason is that the two groups of special police officers of Blue River and Hurricane are slightly stronger than Falcons in terms of strength. The special police competition, reaction speed, on-site response speed, skill ability, etc. are relatively strong. The second reason is that more than a year ago, when Liu Mo was still there, Falcon was involved in a scandal. Blue River and the Falcon team cooperated to encircle a "reading" factory, and the villain resisted stubbornly and held firearms."

Zuo Luo said: "Considering the opponent's firepower and stubborn mental attitude, the police adopted step-by-step tactics to compress their survival and resistance space. Liu Mo and Deputy Zhang, who is still in the drug control office, cooperated with the case, and commanded the special police to control each area step by step. The battle lasted for about half an hour. The special police followed the principle of suppression as the main and shooting as the auxiliary, and used stunt bullets and other pressing step by step, controlling the bad guy in two rooms on a corner building on the second floor. In the end, the main culprit swallowed his gun and committed suicide, and the others surrendered."

"During the operation, the police gave priority to cleaning each room, with two to three special police officers in a group, inspecting all rooms, and finding out whether drugs and guns were hidden. This process lasted about forty minutes. After the safety was announced, the detective entered. The physical evidence team collected evidence, the technical department handled the computer, the forensic doctor collected the body, and a fire broke out in a room, and the firefighter and ambulance came. The scene was a bit chaotic at that time. Although they were under control, they could not pay much attention to the details." Zuo Luo said: "Because the detectives must cooperate with the drug control department to carry out their primary task: get clues on the spot and hunt down other drug dealers as soon as possible."

Zuo Luo said: "Because of the above factors, two days later, Liu Mo called the police and the Interior Bureau intervened. The reason was that among the bad people who were arrested, they said that there were ten kilograms of gold bars in the building, worth about two million yuan. This was a hard currency used for transactions. However, the physical evidence group and others said that the gold was not found. Because the main culprit committed suicide, the accomplices only knew to store it in an area on the second floor, which was cleaned by the Falcon Team at that time."

Zuo Luo said: "Because the criminals possess firearms, the special police all wear sterilized bulletproof vests. A person hides ten kilograms of gold bars, which is equivalent to hiding five packs of cigarettes. It is possible to take away 20,500 grams of gold bars."

The case was investigated for a long time. The Blue River and Falcons team, together with some of the detectives and the anti-drug department police officers, were suspended for one month's leave, and even used a lie detector, but no suspect was found. The Blue River team was involved because a criminal said that things were placed in the second area, and there were special police from the Blue River team in the second area, and three other main backbones said that gold was placed in the first area. Considering that the criminal had a relatively low status in the gang, the police station investigation believed that the Blue River team's crime was very low.

When the investigation was blocked, a member of the Falcon named Zhao Bao disappeared and found the body. The surveillance showed that Zhao Bao's car rushed into the sea, eventually causing drowning. The surveillance captured the photo of the car, which was Zhao Bao driving alone. The police searched Zhao Bao's house and found a piece of stolen gold bar.

However, the subsequent investigation was fruitless. The police even searched the parents who were directly related to Zhao Bao and fixed real estate under the names of their brothers, but found nothing. Two special police officers in the same group as Zhao Bao were also investigated in an all-round way without any discovery.

In the end, the Falcon team returned to work. Although the Falcon team was the third choice before, the attendance rate was still OK. After this incident, the Falcon team basically did not go out for field operations. At that time, in order to deal with these criminals, Falcon and Blue River canceled their shifts and all the staff were dispatched. So afterwards, the three team leaders of the Falcon team had mutual suspicions, and there were some suspicions between the team members.

Zuo Luo said: "Three days ago, the leader of the Falcon team submitted an application for transfer due to lumbar disc herniation. In fact, his condition is not serious. He hopes to make a difference by resigning himself."

"What does this have to do with the Falcon's achievements?"

"It doesn't matter. Maybe he just doesn't want to accept the result of the Falcon being returned to the SWAT team when he was the captain. Once the Falcon is returned to the SWAT team and the organization is cancelled, all personnel will be disrupted and assigned to the detachment's operation team. Some of them are likely to be on standby. The SWAT recruits a certain number of veterans of the same year and replenishes fresh blood every year. Most captains are more willing to train and accept newcomers. They know that even if the Falcons joins their group, they have a higher recognition of the Falcon in their hearts, even if the Falcon no longer exists." Zuo Luo said: "If this is not the case, the gatekeeper special police will not be able to mention this matter to you. The Falcon is now facing the dilemma of disbanding."

Su Cheng said: "Is it true that I am guilty of being suspicious?"

Zuo Luo said: "The suspicion is never targeting the suspect, and we will naturally have higher requirements for sensitive positions."

Su Cheng nodded slowly and stopped saying anything.

...

The First Hospital’s Emergency Department has temporarily stopped working, and the temporary Emergency Department has been transferred to the first floor of the next building. The hospital cooperates very well in this case. Is the doctor using the wrong medicine that caused the patient to die, or is someone who dropped the bag and caused the patient to die? The police cannot explain the details of the case to the public, and at the same time, without clear evidence, it will not be announced that the medicine has been dropped. Therefore, the hospital really hopes that the police can investigate clearly and also give the doctors and nurses on duty a innocence.

The nurse room of the emergency department temporarily became the temporary office of Group 7.

The first question, Zuo Luo asked: "How much malfeasance may be due to the doctor or nurse?" It may be that the doctor used the wrong medicine and changed the label himself.

Zhang Liang replied: "Exclude." He didn't explain too much, and he pushed a piece of material to Zuo Luo.

Zuo Luo didn't read the materials, Zhang Liang said he would exclude them, but he believed it.

The second question, Zuo Luo asked: "When did Liu Yan get poisoned?"

Zhang Liang replied: "The poisoning time is about ten seconds before the twitching occurs, but it is not certain when the poison will come to Liu Yan's hands now. Many people have contacted Liu Yan. Here are the recorded video materials."

Zuo Luo looked at Su Cheng, and Su Cheng said: "The first method is to eliminate emergency doctors. There are at least two emergency doctors at night. The first hospital is equipped with three emergency doctors. Before Liu Yan, a doctor came to the hospital and the patient died in the ambulance. In other words, their visit order is uncertain. I read the transcript and no doctors rush to go out for the field, so I ruled out emergency doctors."

"The second group, Liu Yan entered the emergency room, and the female doctor and four nurses, they could give the poison to Liu Yan. But it was very difficult. Five people surrounded this person, took the electrocardiogram, infusion, and blood draw. The doctor did not participate in these actions. She observed the nurses when they were taking the first step. At the same time, I looked at the nurse's resume and found that they had magic backgrounds. I simulated the movements of the four of them. I thought it was very difficult to hand over the medicine to Liu Yan. If there was no conflict, it would be ruled out. This is my principle, and the nurses would exclude them."

"In the end, there are four suspects, the first person, the female doctor who is the first aid, and she can temporarily rule out. If she is the murderer, I don't think she needs to say that her first aid method is correct. After all, she is cyanide and the king of poison. The temporary meaning is that I am worried that the murderer is too high-end and plays hard to get."

Su Cheng: "The second person is the on-duty doctor. Liu Yan entered the first floor emergency observation ward. She was taken over by the resident doctor. The resident doctors in charge of the night are usually newcomers who have just left the medical school for a few years. This one is no exception. At the age of 26, the on-duty doctor patrols the ward twice at five o'clock and six o'clock."

"The third person, the nurse on duty, was two in total. Only one nurse entered the ward twice. The first time was to check the drip and record the drip when entering the room. The second time was nearly six o'clock, she entered the ward to change the drip."

Su Cheng: "The fourth person is the uniformed female policewoman in the ward. She is Zhang Liang's direct subordinate of the internal affairs department. I believe that her suspicion is close to the female doctor, so it can be ignored for the time being. According to my ideas, now only the nurse on duty and the doctor on duty are left."

Su Cheng: "The most important point is the time for committing the crime, that is, the time for giving the poison Liu Yan. Let's analyze that the nurse entered the ward twice. When the first time he entered, he checked the drip. Liu Yan's needle was stabbed in the emergency room. All she had to do was check and record. At the same time, she signed the order and put the medicine on the bedside at what time. The order was placed on the bedside. It was difficult for her to directly touch Liu Yan's hand, and she could touch her feet when she put the order, but because Liu Yan's left hand handcuffs were clasped together with the bed frame, it was impossible to make too much movement, so the poison was placed at her feet, and Liu Yan could not get it."

"The nurse entered the second time and changed the drip. According to the record, it was 5:47. This time she not only changed drip and signed, but also checked Liu Yan's left hand to see the needle. In the transcript, the female policewoman was on the right side, which was a chance to give poison. She only had this chance, but it was still the reason. She was scolded with her left hand. Liu Yan had to secretly take the poison, and she had to go to the left hand to get the medicine when the female policewoman was not paying attention. She took the medicine..."

Zhang Liang: "Wait, why did Liu Yan take medicine?" Zhang Liang kept hearing this and wondering, Su Cheng's logic was that Liu Yan wanted to die.

"I don't think Liu Yan thinks that's poison..." Su Cheng glanced at Zuo Luo. They suspected that the Ma Bureau had been making criminal plans. If Liu Yan's plan was so good, it would probably be related to the Ma Bureau. But theoretically speaking, this time it was not like a hanged ghost. Su Cheng explained: "Liu Yan deliberately vomited and went to the hospital. She wanted to make herself sick according to a certain plan, but she never thought that her boss was vicious... We won't discuss these for the time being, so we should pay attention to the case itself first."

Zuo Luo said: "The doctor on duty in hospital."

"The doctor on duty on hospitalization entered twice. The first time was with Team Zhang at 5 o'clock. Liu Yan had just entered the ward, entered the examination, and signed with the female doctor to take over the patient. At this time, he had a preliminary examination of Liu Yan, and it was very likely to give the poison to Liu Yan." Su Cheng said: "The second time, at 6 o'clock, the doctor patrols the room again. This time he still checked Liu Yan. In addition to looking at the electrocardiogram and other instruments, he also looked at the pupils and touched the palm of his hand. It was very likely that he would hand the poison to Liu Yan."

Zhang Liang said: "That means..."
