Seeing Ling Ruonan crying in grievance, Wu Yue lowered his head and looked dejected, Luo Ziling finally couldn't bear it.

He wiped his hands clean on his apron, then took out a tissue from his pocket, and wiped away the tears from Ling Ruonan's face.

"Mom, why don't we have a good chat after dinner later," Luo Ziling softened his breath, "Wu Yue and I will tell you everything, and you will make a decision after hearing it. You can decide what place you think needs to be remedied."

"Okay," Ling Ruonan took the tissue, wiped his tears, and then told Wu Yue, "You go out first, report any matters at any time."

"Yes," Wu Yue nodded and walked out.

Luo Ziling and Ling Ruonan continued to be busy in the kitchen, but neither of them said anything more. Except for the sound of the range hood, the others were the sound of cutting vegetables and cooking. The atmosphere was very dull, which made Ling Ruonan feel very depressed and Luo Ziling felt very uncomfortable.

However, neither mother nor son knew how to break this dullness.

When Luo Ziling and Ling Ruonan thought of being angry, there was chaos in the ward.

The emergencies made everyone confused.

Yang Yunzhong, a VIP-level patient who had been living with them for nearly a month and had a stable injury, suddenly worsened. The medical staff immediately started to rescue him, but in the end he was unable to rescue him. The wire on the electrocardiogram monitor that the heartbeat was slowly straightened.

After more than an hour of rescue, the hospital finally announced that the patient died.

When Yang Yunzhong's condition worsened, the hospital called the police as soon as possible. The police rushed to the hospital as quickly as possible and controlled the floor where Yang Yunzhong's ward was located. Most of the leaders of the hospital also arrived at the ward in a very short time.

After announcing Yang Yunzhong's death, the doctors rescued at the scene wrote the rescue cases in full and handed them over to the police.

The doctor in charge of Yang Yunzhong also reported the cause of Yang Yunzhong's death to the hospital leaders.

"The patient is injected with a large amount of potassium chloride, causing cardiac arrest and death." This is what the doctors involved in the rescue wrote on the case and the cause of death they reported on the patient.

It was precisely because it was discovered that high concentrations of potassium chloride were injected artificially that the hospital called the police as soon as possible.

Before Yang Yunzhong was pronounced dead, the police who arrived at the scene discovered an abnormal situation.

A nurse in this ward was found unconscious in the dispensing room, and her work clothes were stripped away.

After the police discovered this, they immediately checked the surveillance camera in the ward.

The monitoring showed that the nurse came out soon after entering the dispensing room.

Because the nurse was wearing glasses, a mask on her face and a hat on her head, no abnormalities were seen from the surveillance.

The nurse pushed a car out of the dispensing room and went straight into the ward where Yang Yunzhong lived.

There were bodyguards guarding the door of the ward where Yang Yunzhong lived, but they did not check the nurses at all.

After the nurse entered, she came out in about a minute.

When she came out, she said a few words to the bodyguard guarding the door.

Whatever you say, the monitoring system without audio collection cannot tell.

The nurse pushed the dressing truck away and walked to the ward on the other side, disappearing into the monitoring range of this surveillance, but soon appeared in another surveillance.

After she walked to the ward that was closest to the elevator, she looked back at the direction of the monitoring, then placed the dressing truck at the door of the ward, and the person walked towards the direction of the elevator. After the elevator door opened, she walked in.

The police continued to investigate the surveillance in the elevator and found that the nurse never appeared again after walking to the washing room in another ward.

Police officers immediately went to the washing room and found a set of changed nurse work clothes in the washing room, but no one was inside.

After inspecting the washing room, the police found that the bathroom was next to the washing room.

After discovering this situation, they continued to check the surveillance and found that several men and women were entering and leaving the bathroom for a period of time after the nurse disappeared.

After looking back and forth at the surveillance screen, the police finally found that the number of people entering and leaving the bathroom was different, and there was one more person leaving the bathroom than the one entering the bathroom.

In other words, the "nurse" left the bathroom.

After making strict comparisons, the police locked in a woman wearing a pink down jacket, a woolen hat on her head and a mask on her face.

After leaving the bathroom, the woman took the elevator downstairs again.

But what is depressing is that the surveillance of the elevator was actually broken and no surveillance video was left.

After checking all the surveillance videos in the hospital, the police still failed to find the woman's trace again.

All the surveillance videos in nearby blocks were also called. The police used a large number of personnel to check all surveillance videos in nearby areas, but still failed to find clues. In other words, the woman disappeared out of thin air.

The situation is also clear. This is an artificial murder case. A person outside pretended to be a nurse and injected a large dose of potassium chloride on Yang Yunzhong, causing Yang Yun's central organ to stop and die.

During the rescue, the medical staff also performed electrolytes and a number of other biochemical tests on Yang Yunzhong.

Among them, the blood potassium concentration is as high as 18.7mmol/l, several times that of the normal upper limit of 5.5mmol/l.

There are also many abnormal indicators that appear synchronously with hyperkalemia.

Originally, Yang Yunzhong's biochemical indicators were basically normal, and the subsequent abnormalities should be the result of hyperkalemia.

The large amount of potassium chloride injection caused Yang Yunzhong's death, and the police also recognized this point, but the medical staff and police officers were puzzled by why Yang Yunzhong did not respond at all when he was injected with potassium chloride.

You should know that when high concentrations of potassium ions are injected into the blood vessels, the pain is simply unbearable.

The patient must have struggled and called, but Yang Yunzhong did not show any such behavior and was always very calm.

This is not very scientific.

The police also took his blood and sent it to the criminal appraisal center to check for abnormal components in the blood.

After the patient dies, the red blood cells in the body begin to be destroyed.

The potassium in red blood cells is released into the body after the cell is destroyed. That is to say, after the patient dies, the blood potassium concentration in the patient's body will quickly increase. The potassium concentration in red blood cells is thirty to forty times that in plasma. The blood potassium concentration tested after Yang Yunzhong lost his vital disease has lost its meaning.

However, the police detected an anesthetic component in the patient's body. The existence of this barbiturate drug that can work for a very short time explains everyone's doubts.

The woman dressed as a nurse injected Yang Yunzhong with a potassium chloride solution mixed with this high-efficiency anesthetic called thiopental, or injected him with an anesthetic first and then potassium chloride. In this way, Yang Yunzhong quickly fell into anesthesia and had no reaction.
