Yan Feifan came to the General Hospital of the Armed Police and met with Dr. Qin Feng, Dr. Gao Yun and others who were waiting here.

He no longer thought about the deterioration of the deep coma patient in the city hospital and the donation of organs, but instead devoted himself to the work in front of him.

This is also impossible to let Yan Feifan not concentrate on his mind.

The brain capacity of modern adult humans is about 1300 to 1500 ml, with an average weight of about 1400g, accounting for about 2% to 3% of the human body weight.

Although the physiological structure of the human brain is the same, the size and shape of development of individuals are different, and the differences are quite different.

This causes the same physiological point to be slightly different in the exact location of each person's brain.

Therefore, Yan Feifan needs high-precision imaging of the prefrontal area and cerebrovascular system of each volunteer.

The relative positions of blood vessels that are as mixed as tree roots are almost fixed and unchanged from the various physiological points of the brain.

Yan Feifan accurately locates the brain position of each volunteer implanted with the discharge device through the shape of the cerebral blood vessels and the relative position relationship with the skull.

The implanted discharge device has a very simple structure.

Its front end is a metal ball with a diameter of two millimeters connected to a thin wire wrapped in insulating paint.

The wire is left outside the cranial brain and can be connected to a precision discharge control instrument to adjust the discharge frequency and discharge amount of micro currents.

After last night's research, Yan Feifan has determined the brain implant location and puncture path of each volunteer.

After he arrived at the General Hospital of the Armed Police, he made a little preparation and devoted himself to his work.

The craniocerebral boreholes are drilled, punctured to a predetermined position, and then the discharge metal ball is implanted from the hollow puncture needle, and finally the puncture needle is removed. The entire disposal process will not exceed five minutes.

It only takes at least one and a half hours for each volunteer to prepare for the preoperative surgery and postoperative observation after puncture to prevent abnormal situations such as cerebral hemorrhage.

Fortunately, considering this situation, the General Hospital of the Armed Police prepared two standard operating rooms for the project team in advance and four temporary operating rooms.

Yan Feifan only needs to be responsible for the most core and most demanding craniocerebropuncture and discharge ball implantation, other preoperative preparation and postoperative observation, etc., all are responsible by other medical staff in the project team.

In this way, Yan Feifan kept busy traveling through various operating rooms and completing one craniocerebropuncture operation.

When he completed all the puncture operations of twenty-four clinical volunteers, the lights were already on outside the operating room, and it was almost seven o'clock in the evening.

From nearly 11 o'clock in the morning to 7 o'clock in the evening, Yan Feifan was busy for eight hours after deducting the ten minutes of lunch.

He moved his wrists, shoulders, neck, and waist, and asked Dr. Qin Feng, who was temporarily acting as his surgical assistant today.

“How are other volunteers doing now?”

Qin Feng replied softly: "Except for the two volunteers who experienced slight bleeding, the other volunteers did not find any unexpected situations."

"The seventeen volunteers who have woken up from anesthesia, after examination, except for pain, did not find any adverse phenomena such as memory loss, subsidence of pain."

"Doctor Yan, congratulations to you, the puncture surgery of the twenty-four volunteers was successfully completed."

Yan Feifan chuckled softly, rubbed his slightly swollen eyebrows, and asked again: "When will the discharge stimulation?"

Qin Feng replied slowly: "The plan is to wait three days later. During this period, one is to let the volunteers resume rest, and the other is to conduct a comprehensive test of their memory ability and establish a benchmark."

"Doctor Yan, are you going to come and go that day?"

Yan Feifan hesitated for a moment, and finally shook his head and said, "Forget it, I still won't participate in the subsequent verification work."

"Doctor Qin, there is a result, tell me."

Qin Feng nodded and responded...

Yan Feifan did not have dinner at the General Hospital of the Armed Police. After saying goodbye to Dr. Qin Feng, Dr. Gao Yun, Lieutenant Colonel Yuan Xu and others, he got into a cayenne car and left the hospital.

After the car drove out of the hospital and entered the main lane and drove smoothly, Yan Feifan asked Duan Yu who was driving.

"Is there any problem with the deep coma patient at the First Hospital of the City? "

Duan Yu replied in a deep voice: "Doctor Yan, Li Yun told me that the deep coma patient is a driver of a public institution."

"Male, 37 years old this year, had a conflict with others after drinking, causing brain injury and falling into a vegetative state."

"Today, he has been in a coma for a year and a month. At six o'clock this morning, he was found to have abnormal brain activity and had difficulty breathing."

"The first hospital in the city has been rescued for more than two hours and has been declared brain dead."

After pausing, Duan Yu added: "He signed an organ donation agreement during his lifetime."

Yan Feifan was silent for a while and said, "To me, his situation is very similar to the situations of the other three people that happened to me and Li Yun and the others found?"

Duan Yu nodded and said, "Li Yun also said that the incident does have big similarities. The joint task force has fully intervened and started an in-depth investigation."

Yan Feifan sighed and looked out of the car window.

The lights passing by quickly outside made his thoughts a little upset.

In addition to this deep coma patient, the first hospital of the city has a great connection point with the affiliated hospital.

More than three months ago, the old director of the No. 1 Hospital of the City retired. Chen Changrui, the deputy director of the affiliated hospital, was transferred to No. 1 Hospital of the City to serve as the director.

Liang Qing, deputy director of the No. 1 Hospital of the City was transferred to the affiliated hospital as vice president of medical affairs.

Could it be him?

In Yan Feifan's impression, Vice President Chen Changrui can be said to be the most low-key among the leaders of the affiliated hospital.

Yan Feifan had very little contact with him, only meeting him several times and greeting him several times, and he had no idea about his behavior.

He took out his cell phone and wanted to call Secretary Liu Jin to inquire.

Half the number was pressed, Yan Feifan gave up.

This kind of thing should be waited for the joint task force's investigation results.

If it is really him, if the news is leaked, it will be bad.

When Yan Feifan looked at his mobile phone, he found that there was an unread voice message from Dr. Deng Chunlin.

"Boy Yan, four hours and seventeen minutes, haha, four hours and seventeen minutes, breaking your record."

"I can't wait to see that guy Lao Gu's expression of envy, jealousy and hatred."

"Haha... I won't piss him to death."

Dr. Deng's joyful voice made Yan Feifan's mood much clearer.

He replied with a congratulatory message...

At nearly 8:20 in the evening, Yan Feifan and Duan Yu returned to Zuimo Huating's residence...

After a little washing up, he was having supper in the restaurant while listening to his sister's chatter.

"Brother Chuan, Yanyan is very happy to go to the north to see the snow with us. Sister Zhong said she was busy with international hospital and had no time to go."

"My aunt is going, and my uncle will go too."

Yan Feifan said lightly, and saw his sister picking up her phone and shaking it in front of her.

I heard her say with smugness: "Freefan, look, you have been spreading the short videos of giving reports in front of so many foreign experts in the conference hall."

"Especially in the nurse circle, those gang of idiots called you one after another to be so handsome and charming."

"Freefan, you're still the best looking in formal clothes."

Yu Suye also echoed: "It's just that the formal clothes look good, especially with Feifan's cold and refusive expression, the arrogant and cold male god style suddenly came out."
