The two of them carefully examined the bedroom without leaving a trace, but found no clues. All the furnishings in this room, except for the two-seater sofa, should be left by Wang Mingxia's parents. And everything that belongs to the victim should have been cleaned up by the murderer.

With the murderer's caution, such a result is not unexpected.

After locking the door again and returning to the hospital the same way, Xu Mingzhi made a phone call and arranged for someone to come and watch this side.

After Yu Guang hung up the phone, he asked, "Do you think the murderer will return to the scene?" ”

Xu Mingyi stuffed the phone back into his pocket and replied, "There is a certain possibility, it depends on luck." It's best if you come, and it's okay if you don't. Now that the identity of the victim has been clarified, it is only a matter of time before the identity of the murderer is found. ”

"Looks like you're confident." Yu Guang said.

Xu Mingzhi raised his eyebrows and said: "The most indispensable thing to do in this business is confidence." We must firmly believe that the heavenly net is magnificent and not leaky, and all sins will eventually be caught. ”

"Really?" Yu Guang glanced back at the rusty courtyard gate and muttered in a low voice.

Xu Mingzhi keenly captured the change in his mood, and after hesitating for a moment, he asked, "There has been no news from your brother all these years?" ”

Yu Guang retracted his gaze, glanced at Xu Mingzhi, and after a hum, he walked forward.

Xu Mingzhi followed, carefully looked at his face twice, and then continued to ask, "No clue at all?" ”

"What? Are you going to help? The afterglow looked like a small talk, and he answered casually.

Xu Mingzhi looked at his face again, and after seeing that there was no displeasure on his face, he replied seriously: "If you have clues, I can help." However, for an investigation to be formally reopened, there must be conclusive evidence. ”

Yu Guang suddenly stopped and turned his head to stare at Xu Mingzhi. The emotions in those eyes are very complex and indistinguishable.

"What's wrong?" Xu Mingzhi was a little confused by his sudden reaction.

Yu Guang said: "It's nothing! I'll look into my brother's affairs myself, and I don't need your help. With that, he turned his head and walked on.

Xu Mingzhi looked at his back and opened his mouth, he wanted to say something, but he didn't know what to say.

In the case seven years ago, although he had asked people to help investigate, he was not sure what he could find out in the end. Maybe it's a little rewarding, or maybe it's nothing. Everything was uncertain now, and he didn't want to tell Yu Guang, lest people look forward to it in vain.

After keeping up again, Xu Mingzhi didn't mention Yu Zhiyuan's matter again. The two tacitly agreed not to speak, and returned to the parking spot in silence all the way.

Xu Mingzhi was the first to break the silence: "I have to wait here for someone to come and take over, do you want to go back to the hotel to rest first, and I'll pick you up when I leave?" ”

Yu Guang replied, "No, I'll stay for one night before leaving." ”

When Xu Mingzhi heard this, he was silent and said, "Okay." ”

Yu Guangtou left without looking back.

Xu Mingzhi watched his back gradually disappear on the country road, and lit a cigarette. When the smoke rose, the phone suddenly rang.

It's Shen Mei's call.

Shen Mei said that Yu Keke's call record had been called up, and the last call was at 4:18 p.m. on May 9. The caller is a foreign number. Yu Keke doesn't seem to have any friends, and he usually has very few phone calls, and most of the call records are with this number.

Shen Mei checked the number, but the number was not registered with her real name, so she couldn't find out who the holder was. However, although the place of ownership of the number is out of town, the signal of each call shows that it is in Yuehu City. Therefore, the holder of this number is at least in Moon Lake City.

Such a result is neither unexpected nor unexpected.

It seems that the possibility of the murderer committing a series of crimes has increased a lot.

Xu Mingzhi was silent for a while before he opened his mouth and asked Shen Mei: "Is there any news from the technical department?" ”

Shen Mei replied, "Not yet." ”

"Let them hold on, and besides, keep an eye on this number. Whenever there is any movement on this number, it will immediately follow the signal and then notify me. Xu Mingzhi commanded in a deep voice.

"Okay." Shen Mei responded.

After hanging up the phone, Xu Mingzhi's cigarette was also finished, he pinched the cigarette butt, threw it away, and got into the car.

The person who took over arrived forty minutes later, and after Xu Mingzhi explained a few words, he drove away. On the way back, he originally wanted to call Yuguang to say something, but thinking of his emotions when he left before, he hesitated for a moment and gave up.

When I was about to arrive in the city, Lao Wang's call came.

"How?" He asked, as he drove.

Lao Wang's somewhat distorted voice sounded in the car stereo: "At the end of last year, a large number of people left the chemical plant, and half of this year's low-level employees were newly recruited at the beginning of this year." When she was injured in the workshop where Coco worked last year, there were a total of 18 workers, and now only three are still the same. I've met all three of them, and they're not in the same class as Yu Keke, so they don't know each other well, and they basically don't know much. However, one of them mentioned that Yu Keke was very close to a male employee named Hong Chao during his post. This Hong Chao is also a native of Dongshan Province, and he is a fellow villager with Yu Keke, and he has not returned since returning to his hometown at the end of last year. There is his mobile phone number on the employee information sheet left in the factory, but it has been shut down, and it is likely that he changed his mobile phone number after returning to his hometown. In addition, Hong Chao's information form is filled with marriage. ”

Xu Mingzhi was silent for a moment, and then asked again: "Have you been to see where she lives?" ”

Lao Wang replied: "I have seen it, she lives in a staff dormitory, a four-person room, and the beds have now been arranged for other employees, even if there is anything left, I can't tell the difference." ”

"Okay, then you can come back first." Xu Mingzhi said.

On the phone, after a pause, Lao Wang suddenly asked, "Do you have any harvest there?" ”

Xu Mingzhi pondered for a moment and said, "The scene was cleaned up, and the preliminary inspection did not find any clues. ”

Lao Wang heard the key point from these words, and said in surprise: "Are you sure it's the first scene?" ”

"The smell of disinfectant water in a room is inseparable." Xu Mingzhi replied.

The car stereo fell silent in an instant.

After a while, Lao Wang's voice sounded again: "The trace examination department has passed?" ”

"Not yet, no hurry. The scene is there and can't run away. Xu Mingzhi said.

On the other end of the phone, Lao Wang was about to get into the car, and when he heard this, the hand pulling the car door paused.

"And what if the murderer returns?" Lao Wang asked subconsciously.

Xu Mingzhi chuckled when he heard this, and said, "Then it's just in time." ”

Lao Wang couldn't help but understand.
