After Li Hua took Wen Yan away, Xu Sa took out the case materials left by Wen Yan's team to study.

There was a diagram of the relationship between several characters on it, and Xu Sa looked at the file, which showed Chen Hui's transcripts.

It seems that Chen Hui has indeed made great progress. I also know how to write the report so fairly.

There are five people with AIDS in total, three men and two women.

One of the men and one woman belonged to the same Department of Neurology, one woman was from the Department of Psychosomatic Diseases, and the other two men belonged to the same Department of Drug Dependence Treatment.

Chen Hui wrote on it: All patients did not receive any blood draw or transfusion during the treatment period, which ruled out the channel of blood-borne HIV; HIV was not detected prior to admission, and mother-to-child transmission was ruled out.

All that remains, there is only one channel of transmission - sex?!

Chen Hui put a question mark and an exclamation mark on the annotation.

In the following column, Chen Hui wrote that every time before the fruit distribution, the patient had to find a partner by himself. Due to the different ratios of men and women, there are several times when there are only two male partners left, and many patients with extreme emotions will lose control of their condition for several days.

When Xu Sa saw this, he felt a little bit in his heart. At this time, the mobile phone rang, and Xu Sa's eyes were still on the file. I just answered the phone.

"Hello Captain Xu, we are the pathology department of the First Psychiatric Hospital." Xu Sa glanced at the caller ID after hearing it.

"I am, please say." Xu Sa is up.

"Here's the case, we've just received the pathology samples from the Third Hospital, but I'm afraid we won't be able to examine them." The voice on the other end of the line was apologetic.

"I need a reasonable explanation." Xu Sa felt that his anger was slowly starting to grow.

"The pathological samples sent by the three hospitals are with the pathogen of AIDS, and if you want to test the samples with the pathogen, you must have an absolutely sterile laboratory to do it." The other party patiently explained.

"I don't believe that you, as the first hospital, don't even have a sterile laboratory." Xu Sa said unhappily.

"We do have it, but the sterile lab is privately owned, so we can't use it without the director's instructions." The other party continued to explain without paying attention.

Xu Sa didn't know how to answer anymore.

"Well, I'm sorry I couldn't help you." The other party still politely ended the call.

Xu Sa suppressed his anger and could only hang up the phone wordlessly, other than that, he couldn't do anything about the other party, but as soon as he heard it, he knew that it was not interesting to be angry at these people.

Looking at the report in his hand, Xu Sa closed the file heavily, and it seemed that it was necessary to see Wei Sen in person.

"Hum-" The phone vibrate, and Xu Sa glanced at it, it was Su Tong.

"Hey, Xu Sa, I've found evidence." Su Tong on the other end of the phone seemed to be very excited.

"Slow down." Xu Sa frowned.

"Didn't I tell you that the two suspicious characters I found quit their jobs at the funeral home after Su Qing's body disappeared." Su Tong couldn't wait to say.

"If someone resigns is suspicious, then I can say that many people are suspicious. Besides, the work of the funeral home is not something that ordinary people can bear, and I can't arrest someone else just because they resigned and took a confession. Xu Sa calmly persuaded Su Tong.

"Of course not, how could I be so childish. I found out that these two people were originally nursing in the First Psychiatric Hospital, and they went to work at the funeral home as temporary workers halfway, and after Su Qing's incident, these two people also went back to work in the First Psychiatric Hospital. Su Tong tried his best to control himself not to get too excited.

"First Psychiatric Hospital? Is it the No. 1 psychiatric hospital in our city? Xu Sa shouted and asked.

"yes, I always feel like I can't get around the First Psychiatric Hospital. Even if you say that I rely only on psychoanalysis, or any intuition, this time, I am very sure that this No. 1 psychiatric hospital definitely has the answer we want. Su Tong said quickly.

"Where are you now?" Xu Sa asked anxiously.

"I'm still at home, getting ready to go out."

"Don't go, Wen Yan is investigating the case there now, if you go, he may go crazy again, I'll go." Xu Sa stopped Su Tong's move to the First Psychiatric Hospital, and for some reason, he had a strong premonition of uneasiness.

"But—" She managed to find some clues... It's a shame to let go of this opportunity like this.

"By the way, what's the name of those two people you're watching?" Xu Sa only glanced at Su Tong's documents vaguely in the morning, and didn't pay much attention to it.

"Oh, one is called Tian Feng, and the other is Zheng Yuanbo." Su Tong's crisp voice came from the other end of the phone.

"What do you say they're called?" Xu Sa seemed to remember something, and opened Chen Hui's transcript in his hand to look through it.

"I said, one is called Tian Feng, the field of the field, the peak of the mountain, and the other is Zheng Yuanbo. Yes—" Su Tong hadn't finished speaking.

"I see." Xu Sa pointed his finger on the table and replied to Su Tong softly.

"Then, if Wen Yan is over there now, I still won't show up, so as not to find out anything and make him feel more worried." Su Tong's tone was full of worry.

"Leave it to me! If I catch both of them, I'll be sure to help you find out. Xu Sa sat on the chair and looked at the words written somewhere.

"Well, be careful." Su Tong hung up the phone after finishing his final advice.

Xu Sa put down the phone weakly. In the list of sick patients, the two male patients who also belong to the drug dependence treatment department are Tian Feng and Zheng Yuanbo.

Heaven seemed to have played a huge joke on him. Everything seems to have a direction and then returned to square one. However, Xu Sa was just depressed, and soon returned to his previous vigorous and resolute behavior.

After Su Qing's body disappeared, the two went to the Third Psychiatric Hospital to see a doctor; Chen Hui had an accident when he met one of them.

This is definitely not just a coincidence, it is a conspiracy. Assuming that these two people have something to do with the disappearance of Su Qing's body, is it that the person behind him wants to kill people and kill people, but if he wants to kill people and kill people, why not just do it? Or does that person still want to use Tian Feng and Zheng Yuanbo to kill them again?

All the mysteries are focused on these two people. The words he said during the meeting kept flashing back in Xu Sa's mind, dividing fruits, bananas, AIDS, biting, illness, Chen Hui was bitten, and refused to be examined......

These various scenes made Xu Sa unable to sit still anymore. Xu Sa immediately left for the Third Psychiatric Hospital.
