The 13 dormitories mentioned by An Zhi and Ning Yide are a female dormitory building on the campus of Ontario University, and this building presents the shape of 13 and has a very distinctive appearance. Moreover, the dormitory manager aunt of this building has very strict requirements for students, and often conducts surprise inspections and scores on the hygiene of the dormitory, so the 13 dormitories are exceptionally clean and tidy, and the girls who enter and exit it are also very beautiful, especially the girls from the music and dance academy. So on the campus of Ontario, the 13 dormitories are often referred to as the Princess Building.

At the beginning, Yasuyuki, who basically didn't live on campus, was also very happy to have a bed in 13 dormitories. In the minds of Ontario students, 13 Dormitories is a clean, tasteful and beautiful representative, and according to general medical knowledge, there are three basic conditions that must be met to cause an epidemic of infectious diseases. That is, the first is the source of infection, the second is the route of transmission, and the third is the susceptible population.

According to the hygiene standards, ventilation conditions and health status of the occupants of the 13 houses, the above three basic conditions are not met, that is, there should be no epidemic diseases. This point is also the most questionable place for the police, and the Meilin Ruhai Community, which also belongs to the high-end intellectual family area, is also an unbelievable thing to have the same strange illness.

Ning Yide still has another worry, that is, Feng Heteng, who has not been arrested for a long time, and Shangguan Xue's "Bone Case", the mysterious person who does not know the details. He always had a bad feeling, as if there were unknown secrets in the first two cases, including the unbelievable epidemic in front of him, all of which were related to the Taiyin organization. Ning Yide didn't want to believe that all the truth might be related to the mutant serum.

For his worries and concerns, An Zhi had no way to empathize, after all, she listened to Ning Yide about the serum. However, looking at Ning Yide, who was full of self-confidence, with an unusually serious expression and tightly furrowed brows, An Zhi could also imagine how tricky the situation was now.

So, early the next morning, Ning Yide took An Zhi and hurried to the police force's autopsy room to watch the first scene of the forensic autopsy. He hoped that the two of them would find a little more clue or some useful guess. No more dead people, that's the one thing he wants to do most right now.

On this day, the deceased who was forensically autopsied was the first person to die of illness in the Meilin Ruhai community.

The deceased was a male, balding of medium height, probably in his sixties, with slender limbs and a bulging belly. An Zhi looked like there were no fatal injuries on the corpse, and at this time, the forensic assistant secretly approached her and whispered to her: "An Zhi, look at this corpse, not only is there no fatal injury, but there are no obvious signs of suffocation!" ”

After the contact with the previous case, An Zhi and the forensic assistant who likes to endorse are already very familiar. It was also like this that An Zhi knew that it took a lot of effort and effort for this little assistant to go from being an assistant police officer to a small assistant who followed forensic medicine and learned forensic medicine. However, he likes the characteristics of endorsement, which has helped me a lot.

An Zhi got used to it and liked it, and he explained some professional terms to her like an endorsement. But this time, when she heard the forensic assistant say the words "signs of suffocation" from the mouth, her brain suddenly looked like a computer screen that had been turned on, and an explanation of a term in Baidu Encyclopedia appeared.

For the first time, she involuntarily said: "The signs of suffocation are the signs of suffocation caused by the retention of oxygen and carbon dioxide in the blood. In other words, signs are signs, i.e., the signs of asphyxia will be different depending on the time of asphyxia and the physical condition of the deceased. ”

Speaking of this, An Zhi suddenly paused, coughed lightly, and continued to reverse: "The longer the suffocation process of the deceased, the more obvious the signs of suffocation will be, and vice versa. Typically, a body that dies of asphyxiation may have the following features: a bluish purple appearance of the face, lips, fingernails, and toenails, and in severe cases, a swollen face. At the same time, the corpse spots appear earlier and more prominently, and the color of this corpse spot will be a deep dark purplish red. ”

As soon as An Zhi's words fell, the forensic doctor stopped the dissection in his hand and said to Ning Yide with a smile: "Professor Ning, your primary school students have made progress." It seems that my apprentice will work harder, and I can't lose to her next endorsement! ”

Hearing this joke told by the forensic doctor, everyone present burst into laughter, making An Zhi very embarrassed. She blushed, looked down at her feet, and pretended to be silent without saying a word, seeing that she was embarrassed like this, everyone stopped joking, and the forensic doctor quickly began the autopsy.

He gently picked up the sharp scalpel and cut open the deceased's scalp in one fell swoop. At this time, I heard the forensic assistant shouting: "Look, the old man's skull is missing!" ”

As soon as his words fell, the police officer on the side spoke: "According to our investigation, we found that this old man had undergone an operation for blood in the brain before his death. His family said that during the operation, doctors first removed the bone flap of the old man in order to reduce the risk of craniotomy. ”
