Chang Qingshan thought for a moment and agreed with Fang Lubai's point of view, he stuffed the key back into his pocket, turned around and walked to a subway station with Fang Lubai.

There are always so many people in the subway, plus it's afternoon, and there are already white-collar workers on the train who are off work. Looking at the old man who had just come up next to him, Chang Qingshan just stood up silently and contributed his seat.

"Hey, what do you see that guy doing?" Fang Lubai pushed Chang Qingshan next to him, and motioned for him to look to the side. I saw a female white-collar worker there, holding the handrail above, and a lewd man behind her was standing behind her, and his body was touching her from time to time.

"Guess what the female collar will do?" He glanced at Chang Qingshan, and also asked him there.

"I don't know how she reacts, I just know I want to hit someone!" Chang Qingshan clenched his fists, wanting to squeeze over there.

"Heroes save beauty? I'm afraid you're too worried, I'll bet that it won't take more than two minutes, and a palm print will appear on the face of the guy in the back. ”

Chang Qingshan didn't believe his words, he just broke free of his hand and wanted to squeeze over there.

There was a clear sound, and the woman slapped her right hand on the left side of his face, and the man covered his face and looked at her innocently.

"Why are you beating people?" He covered his face and looked at her a little bewildered.

"What did you do behind your own back, don't you know in your own heart? Do you want me to show you the evidence? With that, the woman raised the card camera in her hand.

The man didn't expect her to leave evidence, so he planned to squeeze through the crowd and change places.

"Wait a minute, you haven't apologized to me yet!" She looked at the pervert with a cold expression and asked him coldly.

Fang Lubai said slowly: "She knows how to protect herself very well, even if she is weixie, she is not in danger, she knows how to leave evidence, and she is very calm." ”

"Why did I apologize to you, what did I do?" The man was like a scoundrel, denying it there.

"I want you to apologize to me, you don't want to be arrested by the police and put in a cell for fifteen days, right?" The woman still doesn't plan to let the man go like that.

"Some of them have passed." Fang Lubai looked at the woman in front of him and shook his head.

Chang Qingshan saw that the quarrel there was getting louder and louder, and he also squeezed over, Fang Lubai did not stop him, if he didn't come forward again, it would be difficult for this matter to end.

I saw Chang Qingshan squeeze to the man's side and patted him on the back: "It's time for you to get out of the car."

The man's eyes kicked out: "What are you, you want me to ......"

After a while, Fang Lubai put aside the tablet in his hand, turned his head and asked Chang Qingshan: "How is it, have you found anything?" ”

Chang Qingshan just shook his head, signaling that he hadn't found anything, Fang Lubai picked up his lens barrel and began to search for Chang Ying's traces.

A few bells rang from the school, and then a group of elementary school students walked out of the school gate, and parents waited at the door, looking for their children.

"These people don't know the rules as well as the group of elementary school students, and the crowd rushed up, and I couldn't find any trace of Chang Ying again!" Chang Qingshan scolded a few words with a dejected face, and then unwillingly picked up the lens barrel in his hand and looked at the crowd.

"It's okay, we have a positioning system, as long as it's ......" Before the words fell, Fang Lubai felt a hand behind him clapping over.

Without thinking about it, he directly grabbed the hand on his shoulder, pulled it forward, and then lifted his shoulder suddenly, preparing to make the owner of this hand temporarily incapacitated.

But he noticed that something didn't seem right with the hand on his shoulder, and he quickly gave up his next move and turned his head to look at the person behind him.

I saw that the owner of that hand was an uncle in his sixties, and there were several fifty or sixty-year-old uncles and aunts standing behind him, each with a red sleeve on their arm, and seeing that the few people behind him were staring at the two of them with unkind faces, Fang Lubai hurriedly patted Chang Qingshan's shoulder.

"Don't bother me, I finally found Chang Ying's traces again......"

Chang Qingshan's guy didn't notice that something was wrong around him at all, and just looked at the crowd by himself. Fang Lubai tugged at his clothes and motioned for him to turn around.

Chang Qingshan put down the mirror barrel in his hand with an impatient face, and just wanted the other party to lose his temper, but he sent down the group of old people behind him.

"Is this the helper you got in?" Chang Qingshan glanced at the sleeves on their arms and asked Fang Lubai with a puzzled expression.

"People came to the door by themselves, probably they regarded the two of us as suspicious elements......" Fang Lubai picked up the lens tube and tablet in his hand, patted his clothes twice, and looked at the group of old people carefully.

"What do you do? Why are you sneaking around at the school gate? Could it be a human trafficker, ready to snatch children! The old man looked excited and questioned the two of them.

Fang Lubai just wanted to reply, but the old man opened his mouth again: "Don't say anything, are you being thieves?" I'll call the police directly, and I'll see if you two are still talking when I go to the police station! ”

As he spoke, he took out his old man's mobile phone, his fingers trembling and pressing the buttons, Fang Lubai was afraid that things would be big, so he hurriedly took out his police card and came to the old man's side.

"Uncle, we're not bad guys, you see, the two of us are policemen, and our documents are here! The two of us were just on a secret mission and didn't want to be discovered, so we hid here and secretly followed the suspect. ”

As Fang Lubai spoke, he quietly took out the tablet, found that the red dot had not moved, took a long breath, and explained to the old man.

The man stretched out his hand and took the police card handed over by Fang Lubai, and after taking a few careful looks, he took it to the crowd and showed it to the rest of the people.

"We don't know if this document is fake, you two should go to the street office with us, otherwise I will still call the police!"

Seeing that the old men were still reluctantly trying to pull Fang Lu to go to the street office, Chang Qingshan's face gradually began to become impatient. Then he took out his mobile phone and didn't know whose phone number he dialed.

"Hello? Wu Bureau, the two of us have encountered a little trouble, there is a group of old people here in Chengxi Primary School who think we are suspicious elements and want to drag us to the street office, you can just make a phone call to the street office here to explain the problem, and now you are eyeing Chang Ying... Well... Well. ”

Chang Qingshan briefly reported the tracking situation to Wu Wenhui, and then hung up the phone.

"Uncle, you call the street office, and they will tell you if we are from the police." Chang Qingshan put away the phone and explained to the old man.

After the old man hesitated to make a phone call, he asked the other end, and after a while, the old man looked at the two of them with an apologetic face.

"I'm really sorry, we really misunderstood you just now, we just received a report that there are two suspicious men wandering at the school gate here, we thought you were child traffickers, I'm sorry to delay you for so long......"

The old man kept apologizing there, Fang Lubai didn't dwell on the question, and instead asked him who provided the clues.
