As soon as An Zhi finished asking, Ning Yide's cold voice sounded.

He said lightly: "Intussusception in adults mostly presents incomplete intestinal obstruction, and the general symptoms are mild. The danger is paroxysmal abdominal pain, vomiting and the excretion of jam-like bloody stools, but these symptoms are not enough to kill a person or make a person's stomach grow like this. ”

The forensic doctor glanced at Ning Yide approvingly, and continued to explain: "Professor Ning is right, intussusception is not enough to make the old man fatal, and the real cause of his death should be the black-red liquid containing some unknown germs. This germ caused the old man's stomach to change dramatically. It was this great change that eventually led to the death of the old man. ”

Hearing what the forensic doctor said, the two police officers in the room asked in unison, "Forensic Doctor Zhang, can you explain in more detail." My understanding is that the great change is that the stomach becomes larger, and then the stomach compresses the internal organs, which leads to the death of the old man. I don't know if it's right? ”

The forensic doctor wore the back of his gloved hand, gently pushed the glasses on his face, and said, "Your understanding is not wrong, the upper end of the esophagus of a normal person is in the upper abdominal cavity of a person. The lower end of the esophagus should pass through the diaphragm and connect to the stomach in the lower abdominal cavity. Now the problems of the old man also include this place. ”

At this point, he stopped, and the forensic examiner pointed to the black and red liquid on the old man's stomach with his left hand and said: "When I was just dissecting, I carefully touched his internal organs with my hands, and the old man's diaphragm and the sphincter at the lower end of the esophagus felt extremely relaxed. The relaxation of these two parts will exacerbate the abnormal transfer of the stomach position, and when the stomach is stretched out a lot, it will easily run from the lower abdominal cavity to the upper abdominal cavity, and then it will occupy the entire abdominal cavity. ”

The forensic doctor's words explained very vividly, and in front of An Zhi's eyes, it seemed that he could see the picture of the transfer of the stomach position. Then I heard Ning Yide say: "This kind of giant stomach in a person's body will compress his heart, causing people to have abnormal panic reactions. At the same time, the giant stomach can also compress the lungs, causing shortness of breath in the human body. As the size of the stomach becomes larger and larger, the pain felt by the person will become stronger and stronger, and it will eventually kill the person. Forensic Doctor Zhang, am I right to understand that? ”

The forensic doctor said, "Professor Ning is right, it was this situation that caused the death. ”

As a result, there was a sudden realization on the faces of the two police officers. They continued to ask, "Forensic Doctor Zhang, what could that black-red liquid in the stomach be?" It can't be a variation of food, right? ”

The medical examiner said: "The black-red liquid definitely contains food ingredients, but what exactly it is needs to wait for the test report to come out. The only thing I'm sure of now is that the liquid must contain some unknown virus, and it was this virus that caused the stomach of the deceased to change dramatically. ”

Ning Yide said: "Since Forensic Doctor Zhang is so sure, then let's continue the autopsy to see the situation of several other deceased, if the stomach in their bodies also has the same drastic changes, then it can be quickly determined that it is some kind of deadly virus that has killed many people." As long as the virus is analyzed, the culprit can be found. ”

When the forensic doctor heard what he said, he nodded in agreement, and the little assistant, who liked to endorse, immediately pulled over another frozen corpse with interest, and the forensic doctor carefully dissected it. In this way, in the morning, they dissected six corpses, and finally found that the stomach of each corpse contained a large amount of black and red liquid.

However, to the naked eye, except for the old man's big belly, which was particularly bulging, the stomachs of the other five deceased people did not have a special bulge. However, the inner abdominal cavity of the deceased has been filled with a deformed stomach, and the black-red liquid is shockingly present.

When all the autopsies were completed, the medical examiner was more sure of his judgment. Therefore, it is extremely important to wait for the assay report to be released. During this waiting time, Ning Yide and An Zhi returned to Ontario University, and they wanted to do more research in the school to try to find more clues.

Therefore, Ning Yide, who is a professor, went to the school hospital of Ontario, while An Zhi went directly to 13 nights.

13 This building, the overall tone is simple and solemn, it is a strange high-rise building, it has a total of 10 floors. An Zhi's bed is in the 13-bedroom 809 dormitory, and all the dormitories on the 8th floor are occupied by female students from the School of Chinese Language and Literature. The dormitories of the music and dance academy where the accident occurred were all in a relatively low position.

Knowing that something happened to 13 Su, before going back to the dormitory, An Zhi called the girls in the same dormitory and asked about the current situation in the building. According to the girl, the atmosphere in dormitory building No. 13 has been very tense recently. The aunt, who has always been strict, is emotionally tense, so her routine inspections of the students in the building have become much more frequent and tough than before.
