At three o'clock in the morning, on the outskirts of Guangxi County, Lian'an City, Shanshui Courtyard.

This is an upmarket villa complex built on the edge of a lake, which was delivered two years ago and has a lot of land. The west side of the complex is connected to the shore of the lake, and the fence extends directly into the lake.

There are three gates in the community, a small gate for pedestrians on the east side, and a traffic-accessible gate on the north and south sides. It was late at night, and only one gate to the south was open.

At the guard box at the entrance, the young security guard was on duty conscientiously, and even if he yawned, his eyes still kept an eye on the surroundings from time to time.

Yu Guang stood in the shadows not far away and looked at it for a while, then turned to leave.

August 21, 2016.

Xu Mingzhi has not heard from him for two days. He called him a lot, but it was all turned off. He also asked Wang Yongming, but Wang Yongming couldn't contact Yu Guang.

As for the Santana that Yu Guang drove away, he returned to Wang Yongming's second-hand car dealership the day after Yu Guang left, and he drove it back on behalf of him.

Xu Mingzhi was worried that it would alarm Kong Zhendong, and he didn't dare to let the people from the technical department investigate Yu Guang's whereabouts in a big way.

However, the matter that he asked Lao Wang to help investigate before has an eyebrow. This matter was secretly investigated in private, the progress was slow, and Yu Guang probably deliberately wanted to hide his whereabouts, so he changed cars twice in the middle, so it took some effort for the investigators to finally find out where Yu Guang went after coming out of the house that day.

Wanheyuan!

When Xu Mingzhi heard these three words from Lao Wang's mouth, he immediately thought of a person - Wei Minmin, Lin Xiancheng's concubine, who used to work as a political teacher at Xinhe High School, took the initiative to resign in the second year after Yu Zhiyuan's disappearance, and then gave birth to a boy to Lin Xiancheng.

She now lives in the Garden of Nawanhe.

After Xu Mingzhi thought of this, he immediately asked Lao Wang to secretly arrange for a person to go there to confirm whether Wei Minmin's mother and son were at home, and if not, he asked for a monitoring report with the property to bring back.

Lao Wang didn't respond, and looked at Xu Mingzhi with some hesitation: "Team Xu, Yu Guang...... What happened to him? ”

Xu Mingzhi pursed his lips and didn't answer his words, but just urged him to hurry up.

Seeing this, Lao Wang had no choice but to suppress the worries in his heart, and prepared to go out after a sigh.

At this time, Xu Mingzhi stopped him again and advised: "This thing must be done secretly, understand?" ”

Lao Wang looked at him deeply and nodded.

After he left, Xu Mingzhi turned over the information about Wei Minmin that he had shown Yu Guang before. This Wei Minmin has a simple resume, and his life has been simple in the past few years, the only thing that is not simple is that he got involved with Lin Xiancheng, a married man, and gave birth to a child.

On the information in his hand, he couldn't see anything related to her and Xu Zhiyuan.

Therefore, there is only one reason for Yu Guang to stare at Wei Minmin.

That is, it is Lin Xiancheng who has something to do with Yu Zhiyuan's matter.

Xu Mingzhi couldn't help but think of what Su Ning said at that time.

On the night before his disappearance, Yu Zhiyuan quarreled with Lin Xiancheng, who was still the director of the Academic Affairs Office at the time, for an MP3.

However, no matter how ruthless Lin Xiancheng is, I'm afraid he won't quarrel for such a little tongue, and attack a minor boy for an MP3, right?

What else did he not know?

Xu Mingzhi frowned, he had a lot of thoughts in his head, but he didn't sort out any decent clues after a long time. He took the cigarette and walked to the window, clicked on the lighter, and just lowered his head to light the fire, when suddenly there was a knock on the door.

After the ignition was paused, he put away the lighter, turned around and walked to the table to put Wei Minmin's information away, and then spoke: "Please come in." ”

The door opened, and it was Kong Zhendong who walked in.

"Excuse me?" Kong Zhendong's eyes swept over the table and asked with a light smile.

Xu Mingzhi shook his head, immediately picked up the cigarette case, and motioned to him.

Kong Zhendong waved his hand to indicate that he would not smoke, and then unceremoniously pulled the chair in front of the table and sat down.

"Has Yu Guang been in touch with you for the past two days?" Kong Zhendong was straight to the point and very direct.

Xu Ming's heart jumped, then he lowered his head and slowly lit a cigarette, squinted and said, "No, I just called him back, but I didn't get through." As he spoke, he asked, as if he had suddenly remembered, "How was it on Thursday?" ”

"It's stable, there's no sign of deterioration at the moment, but it's not out of danger yet." After Kong Zhendong finished speaking, the fingers resting on his knees lightly tapped twice, and then suddenly stood up.

"If Yu Guang contacts you, help me bring him a message, just say that his brother's case, I already have eyebrows on my side." After speaking, Kong Zhendong turned around and was about to leave.

Xu Ming's heart was surprised, and his face showed a little, and he hurriedly stopped him: "What did you find?" ”

Kong Zhendong glanced at his face: "The identity of the murderer has been basically determined." ”

When Xu Mingzhi heard this, he was shocked again, and subconsciously asked, "Lin Xiancheng?" ”

Kong Zhendong didn't have the slightest surprise or surprise at the guess he blurted out, but nodded lightly: "Judging from the evidence I have so far, he is indeed very suspicious." ”

"Why?" Xu Mingzhi asked.

Kong Zhendong asked rhetorically: "What is your reason?" ”

Xu Mingzhi furrowed his brows, hesitated for a moment, and then said: "Some of Yu Zhiyuan's classmates once reported that the night before Yu Zhiyuan's disappearance, he had a violent quarrel with Lin Xiancheng. Moreover, Yu Zhiyuan's classmate also mentioned that before Yu Zhiyuan's disappearance, the MP3 he was taken away by the teacher did not return to him, that is, the MP3 that was later used to prove that he left school on his own was not left by Yu Zhiyuan, but someone deliberately put it there. This MP3 was taken away by the teacher on duty at the time, and then this MP3 suddenly appeared, no one paid attention to this detail, and everyone tacitly agreed that this MP3 had returned to Yu Zhiyuan before Yu Zhiyuan disappeared. This detail can be ignored by others, but the teacher on duty who took away this MP3 at that time could not have ignored it, but he did not mention it. ”

Why?

There are two possibilities.

One is that the teacher on duty doesn't know who took the MP3, but he doesn't want to get into trouble, so he pretends to be deaf and dumb.

There is also a kind of speculation in his heart that he knows who took this MP3, but the evidence is not conclusive, and the other party's status is higher than his, he doesn't dare.

Xu Mingzhi prefers the latter.

But in fact, either way, it will not affect the final answer. The person who can take the MP3 from the teacher on duty, whether it is bright or sneaky, is unlikely to be a student.

Even so, Lin Xiancheng, who quarreled with Yu Zhiyuan the night before his disappearance, naturally became the most suspicious person.

Of course, Lin Xiancheng was not the only one who had a quarrel with Yu Zhiyuan the night before his disappearance, but also the cause of the whole incident, which can also be said to be the culprit, Yu Zhiyuan's classmate, the classmate surnamed Lin who slandered him for stealing MP3. After that, this person also united with his best classmates and isolated Yu Zhiyuan.

Supposedly, this person is also very suspicious. But at that time, after the class ended at five o'clock, until Yu Zhiyuan was found missing, he had been staying with other classmates during this time period, and he did not have the time to commit the crime.

Another classmate surnamed Lin is also a resident student, and he went to the police to search the school after 5 p.m. that day, and he never left the school during this period. It is almost impossible for him, a student, to perfectly hide a corpse from being found in a crowded school, unless someone helps.

If this is the case, then this person will still only be Lin Xiancheng.

Therefore, in the end, the biggest suspicion in this matter will still fall on Lin Xiancheng.

However, Xu Mingzhi did not say this.

Since Kong Zhendong is already investigating Yu Zhiyuan's case, and he already has some eyebrows, Kong Zhendong will not be surprised by these things that he has not said.

At this time, the two are just testing each other, so naturally there is no need to go into such detail.
