"Xiao Han, you follow up on this matter." Jiang Dong sent the voice file and a few photos sent by Li Yifan to Han Shuo.

Jiang Dong received the things from Li Yifan, it was already noon the second day after the two of them exchanged phone calls, Jiang Dong could only call Han Shuo because his body had not fully recovered, and asked him to follow up on this matter first.

"Boss, what's this?" Han Shuo has been busy investigating Du Jianguo's information in H City four years ago since the morning, and after receiving Jiang Dong's call, he quickly took time out at noon and took Wang Zhi to visit Jiang Dong in the hospital, after all, Jiang Dong had woken up the next day, and Han Shuo met him for the first time when he woke up.

"It was investigated from a place called Changshui Town in City C, and it has something to do with Wu Lianchi and Du Jianguo." After Jiang Dong took Wang Zhizhi away, he used his mobile phone to transmit the information to Han Shuo's mobile phone.

"Changshui Town? Somewhere, how never heard of it. Han Shuo first opened the picture on his mobile phone and looked at it, the photo showed a little girl pointing to a sketch portrait, and a few photos of a township school.

"Li Yifan, they are there to collect style, Du Jianguo used to stay in this school." Jiang Dong looked at the photo on Han Shuo's phone and said. "The person painted on the character sketch is likely to be the 'hands' behind Du Jianguo."

"Li Yifan found it again?" Han Shuo looked at a complete photo of a sketched portrait and said subconsciously.

"Well, the investigation must be carried out in secret." Jiang Dong nodded, originally thinking that Wu Lianchi's later affairs would have to wait for him to get better and then investigate slowly, or to find clues from Du Jianguo, but he didn't expect Li Yifan to help them find a gap so quickly.

"Okay, I know!" Han Shuo knows this better than anyone else. "Found only one person?"

"It's nice to have one person, how many have you found in the past few days?" Jiang Dong glanced at Han Shuo angrily, how long had he been in a coma, how could he feel that the tone in which Han Shuo was talking to himself had changed.

"Hey, boss, we're really tired of being a dog during this time investigating the black car serial murder case, and fortunately, your old classmate sent four of his students to help, otherwise, hey~ I guess I'm already dying of overwork." Han Shuo pretended to be sad and complained to Jiang Dong.

"Oh, okay, I know everything, I've worked hard for you lately." Jiang Dong looked at Han Shuo and said with a smile.

During this period of time, Jiang Dong only heard Wang Xi mention it after he woke up, and of course he knew that they were really busy during this time, and they had been running between C City and H City.

"Boss, it's not that I'm too talkative, lately Wang Zhi's kid will always complain a few words, saying that our team has been excluded, hehe, but I've calmed that kid's heart, young man, it's always like this, and I want to praise if I do something." Han Shuo said with a smile, and raised this question with Jiang Dong as if it was a joke.

"Yes, I know...... It'll get better slowly. Jiang Dong also knew that this was a problem, and he had been working under Section Chief Qin's careful advice and the suppression of the leaders for the past few years. But now, with such a high case-solving rate and the guarantee of his team's ability to handle things, Jiang Dong, the captain, should also return to the courage and momentum he had when he investigated cases in the bureau before.

Until Wang Zhi returned to Jiang Dong's ward, several people chatted a few words, Jiang Dong listened to the two of them tell in detail about the case solving in the villages and towns of City C, and the last victim was Jiao Ting, after hearing Jiao Ting's name, Jiang Dong obviously felt very sorry.

Finally, after pressing the follow-up work and explaining some precautions, Jiang Dong asked the two of them to hurry back to work, while he sat on the hospital bed, opened the recording sent by Li Yifan, and listened to it repeatedly.

"One girl had already fallen ill and died three years ago, and the other gave a complete account of what had happened." Jiang Dong leaned on the pillow behind him and looked up at the white ceiling.

"There is really no shortage of beasts in this world!" Jiang Dong closed his eyes and muttered to himself.

On the way back, Han Shuo had already used the computer to conduct a simple check on the sketch portrait drawn by Li Yifan, but this check came out with more than 100 photos of men who looked similar to Da Mozi, but Han Shuo was really stunned.

"Heh, it's really not ordinary!" Han Shuo reluctantly turned off the tablet.

"Brother Han, what's wrong with you?" Wang Zhi drove Han Shuo's sports car, and did not forget to ask Han Shuo with concern. "Did the captain give you a new mission?"

"Drive your car well, I haven't driven this car myself, if you didn't shout to try it today, I guess it would be scrapped." Han Shuo looked at Wang Zhi and said.

"Don't, Brother Han, don't you know that your car is different, it's really full of horsepower!" As soon as he mentioned this car, Wang Zhi was immediately interested, but he always wanted to experience the feeling of driving a luxury car.

"Okay, okay, it's all here, I can only buy a fried pho downstairs to eat." Han Shuo looked at the time, there was still more than half an hour before the time to go to work.

In order to avoid the traffic jam during rush hour, the two of them spared a long distance and returned to the police station.

"Wang Xi, how are you and the four new members investigating Du Jianguo?" Han Shuo asked Wang Xi, who had never left the office.

"How long have you been out for now, and we can find out the results? You're so versatile when we do. Wang Xi looked helpless.

"I sent you a sketch of a person, and checked it with Du Jianguo's information to find out if the two of them had any communication." Han Shuo sent the photo on his phone to Wang Xi, and did not forget to tell him again.

"Especially to check whether Du Jianguo had any dealings with this person three or four years ago."

"Okay, okay, got it." Wang Xi accepted the photo and did not forget to sigh and chatter. "Hey, I thought that the case would be postponed for two days after it was closed, but I didn't expect this matter to come one after another."

Han Shuo didn't care about Wang Xi's nagging, returned to his position, and quickly edited a text message to Li Yifan. "Is there any other characteristic of the man in the sketch than the place you draw?"

"There is a black mole on the chin, there are hairs, and the chin is protruding forward." As soon as the text message was sent out, Li Yifan quickly replied.

"Got a clue? Now I know that there were four girls with Gao Xiaohong three years ago, one of whom fell ill and died afterwards, and two others did not know who they were. Li Yifan sent another message to Han Shuo.

"Well, if there is a clue, notify us as soon as possible, and we will also seize the time here to further investigate." Han Shuo returned.

The voice message Han Shuo was transmitted to the computer, and he found a headset, sat in his position alone, and listened.
