Chapter 77
March 2 17:7
As soon as he entered the office, Zhou Ning turned on the computer.

In the mailbox, there are four unread emails, with a yellow warning sign on them, which is a specific icon for internal urgent mail, and Zhou Ning opened it nervously.

1. The DNA information of two people was collected on the murder weapon, namely male No. 1 and female No. 2 who submitted samples for inspection, and the blood sample collected on the blood fingerprint belonged to the DNA of male No. 1;

2. There was an occult blood reaction in the urine, and the DNA of No. 1 male was extracted;

3、35-174号样本中，分别找到1号男性和2号女性血液；
4. Among the samples No. 3-34, only the blood of No. 1 male;
5. Pajamas samples: Two samples of blood were extracted from the cut marks on the clothes, No. 1 male blood and No. 2 female urine were extracted from the pants;
After reading the report, Zhou Ning let out a sigh of relief.

However, the system seemed to be silent, and the countdown was still jumping, with no intention of stopping at all. Zhou Ning blinked, a little puzzled. The murderer was Zhang Xin. This is already a certainty. Could it be that the chain of evidence is not complete?

At this time, on the large transparent screen, the content of these reports and the various processes of Zhou Ning's analysis were all displayed, but there was a line of small red characters at the bottom.

Reminder: Please pay attention to the binding person. Due to insufficient evidence in this case, the criminal suspect’s confession is required before submitting the task. Remind the binding person that there are still 50:50 hours left for the task!

Zhou Ning has the wrong teeth, complaining is useless now, the system will not reason with you, or negotiate, you must complete the task as required, but that Zhang Xin is still pretending to be crazy, how to do this?
At this moment, Liu Yongxin opened the door and came in. Seeing Zhou Ning, he blinked and asked:

"You kid, why did you look like a lawsuit so early in the morning? Is there something wrong with the report?"

Zhou Ning shook his head.

"The report is fine."

"Then why do you have this expression? By the way, why don't you tell me what illegal things you guys did secretly? You have been keeping it from me for a day."

Zhou Ning smiled embarrassedly, and grabbed Liu Yongxin's arm.

"Master, don't worry, if you say it, you won't have a sense of mystery. Don't worry, it's definitely not a violation of law and discipline. It's just that this trick is a bit bad. Let's call Xu Da and go to the Eighth Hospital to see. I think it should be Time to check the results.

The test report just now made it very clear that Wen Haicheng's wound was only his blood, while Zhang Xin's wound had the blood of both of them. The blood on her pants was also Wen Haicheng's, and there were fingerprints and blood on the murder weapon.

Now the evidence points to Zhang Xin, but in such a case, relying on these characterizations alone is still a bit weak. I think at least let Zhang Xin speak up, pretending to be crazy will not escape legal sanctions, and she will even be given a heavier sentence. We will force her to stop pretending Crazy, to get a trump card for this. "

"Wait, there's a trump card. What kind of structure is there in your head? It's a set of things?"

Zhou Ning was a little embarrassed. He couldn't say that he was forced by the system, and there was not much time left in the countdown. He had to work harder, or he would really be struck by lightning!

Zhou Ning took out his mobile phone and dialed Da Zhao's mobile phone.

"Are you coming?"

"Just arrived downstairs, shall we go now?"

"Wait for me, I'm going downstairs now, the camera has applied?"

"Don't worry, it's an absolutely professional camera, don't get inked, go downstairs quickly."

Zhou Ning grabbed his down jacket and ran outside. Liu Yongxin didn't ask any questions this time. He watched Zhou Ning leave, but leaned against the door frame and looked at Zhou Ning's figure.

As if he heard the sound of running, Xu Dayuan came out from the next door. Seeing Liu Yongxin looking at the stairs like this, with a smile on his face, he came over with a gossip.

"What are you laughing at? Why, your son has a girlfriend?"

Liu Yongxin rolled his eyes.

"Looking at my apprentice makes me happy, why are you envious?"

Xu Dayuan smiled.

"Come on, this sentence kills me, I'm envious, why don't you come, but why did your apprentice go?"

Liu Yongxin shook his head.

"From Da Zhao's point of view, it seems that he took professional camera equipment with him. I don't know what to do, but don't worry, it will definitely help the case. I am absolutely sure of this. This kid is so similar to when I was young! "

"Didn't you ask why they went?"

Liu Yongxin laughed heartily, and waved his hand at Xu Dayuan.

"secret!"

15:30
The Office of the Neurologist of the Eighth Hospital.

In one corner of this place, a computer has been placed. On it is a picture of a ward. There are two beds in the ward. Zhang Xin is lying on the bed by the window, grabbing the quilt, shaking his head and biting continuously.

A doctor stood beside Xu Dayuan, smiling helplessly.

"The nurse who fetched the water in the morning spilled food on the bed at noon. By the way, she squatted on the bed to urinate yesterday. This ward is dirtier than the bathroom. I said, Xu Da, what are you doing?"

Xu Dayuan patted the doctor on the shoulder and said comfortingly:

"Be patient, you have consulted her, right? Are you mentally okay?"

"To tell you the truth, I can't tell whether it's an act or a real mental disorder. However, she has been in such a noisy state, which is relatively rare. We wanted to monitor her brain waves, but we couldn't do it at all, and we couldn't cooperate!

Therefore, it is impossible to judge whether she is really sick or just pretending, but judging from my experience, she does seem to be pretending. "

Hearing what the doctor said, Xu Dayuan also became more confident.

"Director Liu sent a nurse, and the person on the hospital bed next to the door will push it out."

When Director Liu went out to make arrangements, Liu Yongxin poked Zhou Ning with a dazed expression.

"How long do you guys want to hide from me? What are you guys playing? Am I still your master?"

Zhou Ning clasped his hands together and said with a smile:

"Master, I didn't intend to lie to you. It's not that Xu Da is playing tricks and wants to joke with you. Take a closer look, does the person in bed No. [-] look familiar?"

When Liu Yongxin heard this, he moved closer to the monitor and took a closer look with surprise on his face.

"Isn't this Zhang Wanshun from the criminal police team?"

Xu Dayuan laughed twice.

"How about Liu Fayi, this disguise is okay. Your apprentice came up with the idea to let our people pretend to be patients, and then transfer Zhang Xin to the ordinary ward where they are. At this time, we will monitor and observe at this time, so we can judge whether she is pretending to be crazy."

Liu Yongxin clicked his tongue and kept shaking his head.

"This tactic is a bit of a loss, but it seems to be effective."

Seeing Zhou Ning and Liu Yongxin looking at the door, Xu Dayuan was stunned for a moment, and he also turned his head, seeing Zhang Wanshun sitting in the wheelchair, Xu Dayuan gritted his back molars, forced himself to hold back his laughter, and nodded solemnly.

"Xiao Zhang has worked hard, how is the situation?"

Zhang Wanshun is a very thin criminal policeman. I guess he was chosen because of his height and appearance. After all, wearing a wig and underwear, there is no sense of disobedience at all. He looks like a real Aunt Qindao.

"Xu Da, if you don't pick me up again, I can't help but beat someone up."

Xu Dayuan slapped Zhang Wanshun on the shoulder, and Zhang Wanshun tore off the wig directly, almost crying because of his grievance.

"Hit me, I won't go, this Zhang Xin is a lunatic."

"you sure?"

Zhang Wanshun snorted twice, and then said:
"I'm just complaining. Zhang Xin is pretending to be crazy. After turning off the lights at night, she will be honest for a while and secretly observe whether I am asleep. After twelve o'clock, she starts to eat the steamed buns hidden under the pillow. Although she urinates on the bed during the day, she absolutely Not peeing in bed."

Xu Dayuan breathed a sigh of relief, and smiled at Zhang Wanshun.

"You go to rest, it's hard work! Da Zhao will monitor and find the time Zhang Wanshun said, and see if it is captured?"

When Zhang Wanshun heard this, he grinned and rushed to the sink in the doctor's office to wash off his face. Da Zhao had already followed the person in charge of monitoring to find the video after twelve o'clock.

Although the lights were turned off, part of the door of the hospital was made of glass, just to observe the patient's situation well, so the light in the corridor was enough to see the situation in the room clearly.

Sure enough, at 12:34, Zhang Xin got up, went to Zhang Wanshun's bedside, and deliberately clapped his hands next to his ear. Seeing that Zhang Wanshun didn't respond, he tiptoed back to the bed, and took out steamed buns from the pillow to eat.

Director Liu followed suit and tapped on the table with his fingers.

"There is no need for an EEG. This person is pretending to be crazy, and his thinking is very clear. I can give you a diagnosis in a while. Of course, if it is transferred to the procuratorate, a mental evaluation will be carried out later. There is an appraisal center at the city bureau. can do."

"Thank you, I have caused trouble for your department. The little nurse who was beaten, please help me calm down. After that, if you want a pennant or a pennant, I will apply here if you want a bonus. What do you think?"

"Come on, I'll be thankful to take him away quickly."

With a wave of his hand, Xu Dayuan put away the smile on his face.

"Let's go. Forensic Doctor Liu and Zhou Xiaozhou will follow along. It's time for your secret weapon to be revealed!"

　Let me tell you one thing, I will go out for a few days early tomorrow morning, and I will come back at midnight on the [-]th. The updates are scheduled, and I don’t worry that the updates will not be interrupted. Read the book and leave a message, I want to like to listen to it! (Tsundere face)
