Chen Jing moved her right hand away from the mouse and stared at the computer screen, thinking silently.

Now that it is known that there was a mastermind behind the scenes who deliberately tried to harm the lives of their group, then the cause of death of the three seriously injured students in the hospital is definitely strange.

During the surveillance, no traces of outsiders were found, so it is very likely that it was done by someone within the hospital department.

Although I don’t know what methods the other party used to worsen the condition of the three people and lead to death, and even the medical equipment did not detect it. But as long as they are caught and interrogated, it will be enough.

According to the duty records, a nurse was indeed in charge of the intensive care unit from February 14th to February 21st, so as the one who spent the longest time with her, she was highly suspicious.

Chen Jing glanced at a name on the screen and said to the restless head nurse: "There is a female nurse named Feng Mengfan in your department. Please call her over."

When the head nurse heard this, she looked embarrassed and said, "I'm sorry, she's not here now."

Hearing this, Chen Jing frowned and listened patiently to the head nurse's explanation.

"She took annual leave some time ago. I heard she was going to travel abroad with her family, but she hasn't come back yet."

"When did she leave?" Chen Jing asked.

"March 1st." The head nurse thought for a moment and said.

"At this point in time, the cause of death of the three seriously injured students has been officially concluded. If I had taken leave at that time, I would not have attracted attention."

Chen Jing thought in her mind. If she couldn't wait to go out after the death of those three people, then any fool would know that there was definitely something wrong with her.

If he had only doubts about the nurse named Feng Mengfan before, it was absolutely certain now.

"Does the head nurse know when Feng Mengfan will return to China?" Chen Jing asked again as she took out her cell phone.

The head nurse also felt something was wrong at this time. Could it be that Feng Mengfan really got into trouble?

It shouldn’t be! Although this girl Feng Mengfan is taciturn, she is serious and responsible in her work. She is an honest girl. How could she get into trouble with the Security Bureau?

Chen Jing didn't wait for a reply and repeated it slightly louder.

The head nurse was woken up, and she stopped thinking about it and said quickly: "Calculating the time, it only lasts a few days."

"Did you contact Feng Mengfan during this period? Did he tell you where to visit?" Chen Jing then asked.

"I have no contact, but Xiaoliang is very likely. She is Feng Mengfan's best friend."

After speaking, the head nurse called Xiaoliang over and asked.

Xiaoliang, a young girl with a festive round face, shook her head when she heard this and said: "I have sent several text messages and called several times before, but Mengfan didn't respond. I don't know why.

"

Well, it seems that that person will not come back again.

Chen Jing sighed, it was still too late.

But I still have to check again.

He took out his mobile phone and sent Feng Mengfan's personal information to a technician from the Security Bureau, asking to find out her and her family's relevant account information and consumption records, and also check her family status during this period.

I politely thanked the head nurse, and when the other person hesitated to speak, I went to the doctor's office and found the attending doctor of the three of them at that time.

As before, after an introduction, Chen Jing asked about the symptoms of the three people at that time and whether there was anything wrong.

The doctor who was facing the Mediterranean recalled for a while, and just said that the three people were unlucky. They also tried many methods, but the other party's injuries were too serious and it was difficult to save him in the end.

"If you really want to talk about it, it can be said that I am a little confused, that is, the organ failure of the three patients was too fast, and our drug rescue efforts could not keep up."

"Of course, this kind of situation has not happened before, but the probability is very small, so I say they are unlucky."

Chen Jing, who was watching the cases of the three people, raised his head when he heard this and wrote this down.

…

When Chen Jing took a few steps out of the doctor's office, there was a crisp sound of high heels hitting the marble floor behind her.

Chen Jing naturally knows who it is.

There was not only the Mediterranean doctor in the office before, but Dr. Xia, who had a very good temperament, was also working there.

At that time, she showed a very surprised expression when she saw herself.

Sure enough, looking at this elegant Ruolan with a face full of collagen, Chen Jing said hello:

"Dr. Xia, you're done."

Xia Qin also said hello, and then asked curiously: "Chen Jing, when did you become a member of the Security Bureau?"

She had seen the information about Chen Jing being hospitalized before. He was obviously still a student at Jiangnan Military Academy, and he became a member of the Security Bureau just a short time later. He couldn't be pretending.

Xia Qin's eyes already had such meaning.

Chen Jing did not want to be regarded as a liar, so he had to briefly talk about the cooperative relationship between Jiangnan Military Academy and the Security Bureau.

Xia Qin suddenly realized, and then said: "You are here to investigate the death of the three students at Nansu University."

Chen Jing nodded. He didn't intend to block others when he asked the question before. It was normal for the other party to know this.

"Actually, I have participated in the treatment of those three people before. I made a discovery among them, and I don't know if I can help you." Xia Qin said and handed the document in his hand to Chen Jing.

Chen Jing took it curiously, opened it and listened to Xia Qin's narration at the same time.

"There is a chemical component in the blood of those three people that no one else has."

"H3O-P4."

"The explanation is that it is a special formic acid component."

"It is the existence of this thing that greatly weakened the immune systems of the three people, accelerated organ failure, and ultimately led to death."

Hearing this, Chen Jing realized something was wrong and asked directly: "Can this kind of formic acid be mixed by itself and used for poisoning or something like that?"

Xia Qin paused for a moment and replied: "Theoretically it is possible."

Chen Jing was puzzled: "Then why didn't the doctor explain this possibility to the police before?"

"At the beginning, doctors thought that this formic acid came from red-armored ants. After all, they were injured because of these savage beasts. It is normal for the wounds to contain this kind of formic acid." Xia Qin explained.

The flame that Chen Jing had just started was extinguished in an instant. This cannot be used as evidence of homicide.

However, at this time Xia Qin changed her tone again and said in detail:

"But later on, when I had nothing to do, I also studied the formic acid in the three people's bodies, and discovered a characteristic, that is, it is very potent."

"At that time, the hospital also received many patients injured by red-armored ants. I also studied them one by one and found that the acid intensity in their bodies was much lower than those of the three."

"In terms of levels, the others will be able to withstand at most one or two levels of brutal beast formic acid. As for those three people, they must be at least level three, maybe more than level three."

"Because I don't know the specific experience of these three people, I thought they were very unlucky to encounter a third-level savage beast, so I didn't pay much attention to it."
