At this time, the security guard turned to Mo Xiaoqing and said, "Comrade police, look here there is something wrong. Someone on the first floor threw the cleaning car into the aisle, and then went into the toilet next to it. When he came out, he had changed into black clothes and black pants, and was wearing a hat and a mask."

Mo Xiaoqing quickly stared at the surveillance camera and saw that the man was indeed suspicious. She quickly took the phone and called Xu Yao.

"Captain Xu, the suspect who pretended to be a cleaning staff from the fifth floor is now going out of the southwest gate of the hospital.

He is now wearing black clothes and black pants, and wearing a hat and a mask."

At this time, Xu Yao had already rushed out of the hospital gate. After receiving the call, he immediately turned back and ran to the southwest.

Relatively speaking, the southwest of the hospital has relatively few people, and this is the back door. Going out is a dilapidated residence, scattered all over the place, with overhead wires tangled and randomly intertwined.

Xu Yao followed the surveillance information provided by Mo Xiaoqing and kept chasing forward.

He went into a small alley, went down the stairs, and in front of him was a very empty and quiet long tunnel.

Xu Yao looked up and suddenly saw a man in black clothes and black pants walking quickly in front of him.

His heart skipped a beat, thinking that this was most likely the suspect. He chased forward quickly, but did not dare to make too much noise.

When there were only ten meters left, Xu Yao became more and more nervous, and the suspect running in front of him did not notice his presence.

But as luck would have it, Xu Yao accidentally stepped on a duck toy on the wet ground.

With a squeak, the man in black in front of him looked back abruptly. Xu Yao stood there nervously, motionless.

He could see the alert look on the mask of the man in black just by looking up.

Xu Yao slowly put his hand to his waist and touched the pistol.

The man in black in front of him also realized the danger, turned around and ran away.

Xu Yao shouted, "Stop, if you run again, I will shoot."

The man in black in front of him did not stop at all. Xu Yao shouted a few times and chased him desperately.

The man in black also rushed forward desperately, bumping around in the alleys of this old city.

After walking back and forth in the alley for three or four minutes, Xu Yao, who was following closely behind, looked forward and saw that the man in black in front of him suddenly disappeared.

Xu Yao pulled out his pistol, held it in one hand, and stepped forward cautiously.

Only then did he realize that he had entered an abandoned courtyard that looked like a courtyard house, and there was no one inside.

Xu Yao just raised his foot to step over the threshold when he suddenly felt a palm wind hitting his face.

He reacted immediately, tilted his head, and grabbed the outstretched fist.

But the other party rushed out, raised his right foot, and kicked Xu Yao's thigh.

Xu Yao was forced to let go of his fist and step back, but the man grabbed Xu Yao's arm with both hands and was about to hold his arm to press him to the ground.

This set of fixed grappling routines was simply no match for the brave and combative Xu Yao.

Xu Yao turned around and ran away, stretched out his right hand and suddenly grabbed the man's arm and turned it back, and pressed his left hand on the man's chest, trying to strangle his neck.

As soon as Xu Yao touched the man's chest, he was immediately confused, it turned out to be a woman.

The woman in black who was fighting with Xu Yao was obviously at a disadvantage, and her arms were about to be locked behind her and unable to move.

Xu Yao shouted, "You'd better not move."

But before Xu Yao could react, he felt a layer of powder suddenly floating in front of his eyes, and soon he could feel a burning pain in his eyes.

Xu Yao immediately took a few steps back in pain, squatted on the ground, and pressed his eyes.

Crying out in pain.

Xu Yao couldn't open his eyes and could only listen to the hurried footsteps running farther and farther away.

He cursed in his heart, damn it.

Less than two minutes later, Xu Yao heard the loud sirens and hurried footsteps behind him.

Mo Xiaoqing had already run out of the hospital's surveillance control room,

and the notified police colleagues also rushed over, but it was still a step too late, the suspect had already escaped.

When Mo Xiaoqing hurried to the scene, she found Xu Yao squatting on the ground in pain, pressing his hands on his eyes.

She hurriedly ran over and asked, "Captain Xu, what's wrong with you? Where are you injured?"

The police officers who heard the news and rushed to the scene immediately dialed 120 for emergency treatment, and the ambulance arrived within five minutes.

The remaining police officers all split up and continued to search for the suspect.

Xu Yao was sent to the hospital for examination. Fortunately, Xu Yao's eyes were fine. The person sprayed him with the usual anti-wolf spray.

After simple treatment, Xu Yao's eyes were finally able to open, but the eye sockets were still red and swollen.

Xu Yao got down from the bed and asked to be discharged, which scared Mo Xiaoqing. "Captain Xu, it's already like this, you should just stay in the hospital for treatment."

"Don't talk so much nonsense, this little problem won't cause any trouble. I wanted to capture her alive, but I didn't expect her to resort to such a despicable trick."

Xu Yao said this angrily, and his cell phone rang. Liu Xiaobo reported when he picked it up:

"Captain Xu, Mr. Chen must have died because his respirator was pulled out.

And we found an unconscious nurse behind the staircase door on the first floor. Her clothes were stripped off.

But now she has woken up, and our people are taking her statement."

"Okay, you take charge of the situation, I'll come right over."

After Xu Yao finished speaking, he quickly put on his shoes and turned to Mo Xiaoqing and said, "Go buy me a pair of sunglasses as quickly as possible.

Mo Xiaoqing looked up in confusion, and Xu Yao said again: "Go ahead, how could I, who has always been handsome, let my image be ruined?"

Mo Xiaoqing almost laughed out loud, Xu Yao really knew how to make fun of misery.

In the end, she did not choose to buy sunglasses, but borrowed a pair of sunglasses from the doctor in the hospital for Xu Yao to wear, and the two hurried to the fifth floor where the accident happened.

As soon as Xu Yao arrived at the scene, he asked Liu Xiaobo directly, "How is it? How is the unconscious nurse now? Did you find out anything?"

"Captain Xu, this nurse just woke up and her reaction is still slow, and she didn't see the suspect's face."

Xu Yao decided to ask in person and pushed open the nurse's bed. The nurse was now sitting on the bed, staring at the white wall in front of her with confused and empty eyes.

"Hello, nurse, I am the criminal police captain Xu Yao.

May I ask if you have recovered your memory now? I want to ask about the process of you being unconscious at that time.

Did you see what that person looked like?"
