The mother and daughter quickly hid in the place they had agreed upon earlier, making sure that no one coming in could see them.

There were voices in the yard.

"What's going on? Dongzi hasn't been seen since yesterday afternoon."

"Why didn't the old cat and the policeman give the signal according to the regulations?"

"I don't know."

"I was just nervous, so I came back to see if everyone was there, and I just happened to meet you at the door."

Four men came in.

Song Qingyun's eyes lit up slightly. The more people they caught, the less likely they were to lie.

If this person doesn't say anything, another person will say something. If this person says less, another person will say more. So the more people there are, the more convenient it is to interrogate.

Song Qingyun was in a good mood.

Xia Changle was also in a good mood, but her hands were itching. She felt that she was extremely energetic all night and had no chance to show her energy.

The mother and daughter each had their own thoughts and were silently observing the situation outside.

The person walking in front opened the door and said, "The door is not locked. Do you think the old cat has returned?"

"Who knows?"

"No, considering the old cat's alertness, it's impossible for him to remain silent now that we've entered the yard."

"No matter how I think about it, it doesn't feel right."

"Okay, let's go inside and discuss this."

After the four of them finished speaking, they entered the house one after another. When they entered, a puff of white smoke swept across their faces.

None of the four noticed.

But after just two steps, four people fell to the ground one after another with a bang, and they were piled up like a monk.

Xia Changle clapped his hands and walked out from his hiding place.

"What Suihe gave me is really powerful, Mom. Look, I didn't even have a chance to do anything, and they fell."

Song Qingyun chuckled, "Alright, find some ropes to tie the guy up first, and then wait an hour. If no one shows up, we'll notify the police to come and take him away."

"Okay." Xia Changle responded and quickly found the rope. She used the method her master taught her to tie the four people together.

"How are you going to walk when you leave when you're tied up like this?"

"Let them walk sideways." Xia Changle said with a smile.

Song Qingyun was amused by Xia Changle and was at a loss whether to laugh or cry.

The two waited for more than an hour, but no one came. It was also the time they had agreed with Qian Xiao.

Qian Xiao was not idle that night. Although he was not as energetic as Xia Changle, he slept all day.

And since I'm young, staying up all night is no big deal.

He was curiously observing the guesthouse across the street through a telescope. Originally, Qian Xiao was looking at their own room.

It turned out that theirs was not the only room in the guesthouse worth observing.

Something also seemed amiss in their downstairs room.

So Qian Xiao stared at the room and found that someone was entering and leaving the room in the middle of the night.

Qian Xiao wrote down everything he saw.

They plan to report it together tomorrow. If they can catch any bad guys, it will be a great achievement. Qian Xiao will be very happy.

When the time came, Song Qingyun and Xia Changle called their neighbors to help report to the police.

Qian Xiao did the same thing.

They have to keep an eye on the prisoners, otherwise it will be a waste of money if there are any mistakes or omissions.

They arrested so many people, it was impossible for them to keep a low profile, and soon the police arrived.

The one who came to Song Qingyun and his team was Song Yuanchao.

The one who went to Qian Xiao was another deputy captain.

Qian Xiao briefly explained the situation, and everyone carried the tied-up man back to the police station.

Song Yuanchao saw five big men tied at the feet of Song Qingyun and Xia Changle.

Song Yuanchao gave a thumbs up and said, "Changle, you are really amazing. We have the Shanghai Public Security Competition in a few days. How about you participate on your uncle's behalf?"

Xia Changle blinked, "Can I? Can I?"

"Of course you can. You will be my special recruit from now on. Although you are young, I will definitely allow you to get a certificate and officially become a member of our public security comrades."

Song Yuanchao's eyes were shining as he looked at Xia Changle.

Not to mention that the child is now nine years old, which means she was five years old. Song Yuanchao dared to slam the table and say to their director: I must have this girl!

No matter what conditions she puts forward, just agree to them. If you don't agree, I will fight you.

Xia Changle grinned, and Song Qingyun patted Xia Changle helplessly.

Xia Changle immediately restrained her expression. Yes, her master said that people who practice martial arts should not show their emotions on their faces.

But she couldn't stop laughing, she was so happy!

Xia Changle was in a good mood, and the group returned to the Public Security Bureau.

The mother and daughter stayed up all night last night, and Song Qingyun didn't want to participate in the interrogation.

"Captain Song, the mastermind behind instructing Chen Guiqin to abduct my husband and Changle. I asked my husband and he said he didn't know her, but Changle said she had seen her."

Song Qingyun handed the portrait to Song Yuanchao. She drew two portraits in total. One was a portrait of Secretary Zhang in disguise, wearing a hat and a mask with only a pair of eyes showing.

One is the full picture that Ergouzi saw.

"This is Secretary Zhang." Song Yuanchao exclaimed in surprise. He never expected that the deputy mayor's second secretary would be the mastermind behind the human traffickers.

Song Yuanchao thought of a lot of things at once.

Is Secretary Zhang's cooperation with the human trafficking group occasional, or is there a long-term chain of interests between them?

If there is a long-term chain of interests between them, then Secretary Zhang can obtain a lot of intelligence in the Shanghai Stock Exchange?

Could it be that the human trafficking organization has already targeted the families of important city government officials or some other important figures?

"Teacher Song, this matter is too complex. I'm going to the city government right now to ask for their assistance in the investigation."

Song Qingyun nodded, thinking that you would be even more shocked when you get to the city government.

Song Qingyun and Xia Changle said hello to everyone and went back to the guesthouse to rest.

When they returned, Xia Weian was waiting at the door.

The three of them did not have time to inform Xia Weian about the impromptu action last night.

Xia Weian came to deliver breakfast and found that the door was locked from the outside.

He realized something was wrong and simply waited at the door.

Fortunately, Song Qingyun and Xia Changle came back not long after.

Qian Xiao did not come back with them.

Qian Xiao discovered last night that the people in the room downstairs seemed to be doing some kind of deal, and it didn't look right.

He reported the situation to the deputy captain.

After receiving the information, the deputy captain immediately launched an investigation.

Qian Xiao observed for a whole night, and the deputy captain simply asked Qian Xiao to cooperate with their actions.

Xia Changle and Song Qingyun both had smiles on their faces when they came back.

"Where are you going?" Xia Weian asked.

Xia Changle rushed to Xia Weian and said mysteriously, "Dad, the three of us did something big last night..."
