Xiao Ran put on gloves and wiped the bed where Xi Ruxiang slept for a few times, "The bed board has fallen from dust."

"From the degree of falling, it should have been a while, but it will not last more than a month."

Zhang Lei took the camera and took photos around, thought for a moment and said, "It was cleaned very carefully at that time, maybe it was made by a girl."

"The chances are not high for girls. Generally, girls dare not come here."

Mo Xiaobei looked at the dormitory with his back to the window and said, "Some boys are as delicate as girls."

"Will it be with the park?" Zhang Lei looked at Xiao Ran and said vaguely.

"It's possible, but nothing is left here, and we can't forcefully connect the two."

Xiao Ran understood what Zhang Lei wanted to say, shook his head gently, and asked the security captain: "Uncle, are the surveillance monitors in the school in the security department, right?"

"Yes, but it's not easy to show to people, and there are not too many cameras here." The security guard nodded.

"We know this. When you go back later, let me tell the security department. Don't remove the surveillance regularly for the time being. After we sign the investigation certificate, we will come to adjust the surveillance." Xiao Ran said.

"Okay." The security guard replied.

"I would also like to ask, why didn't you call the police when someone of you witnessed Xi Ruxiang?" Xiao Ran asked, looking at the security guard.

"What do you mean by this..."

The security guard smiled awkwardly and said, "Everyone said this matter was haunted, and Xi Ruxiang's case had already made it difficult for the school to do. For such a ruling and unfounded thing, the leader no longer wanted to push the school to the forefront."

Xiao Ran didn't say much, he probably understood the school concerns that the uncle mentioned.

The school leaders also don’t want the masses to remember the misfortune of the school when they mentioned the School of Commerce and Trade. They try their best to downplay the name Xi Ruxiang, which is beneficial to the school’s reputation.

"This is my mobile phone number. If anything goes wrong here in the future, I will make this call."

Xiao Ran tore off a piece of paper from his portable notebook, wrote down his contact information, and placed it on the corner of the table in front of him.

"OK."

The security guard responded, and just reached out to pick up the paper when a gust of cold wind rushed in from the corridor.

The dormitory was immediately dusty, and the paper on the corner of the table was also swept up by the wind. It passed through the gap between the window guardrails and floated out and disappeared.

"Haha, natural phenomena, natural phenomena."

Zhang Lei said calmly with his camera in his hands, not caring about his appearance, but Xiao Ran expected that Zhang Lei must be screaming in his heart at this time.

Xiao Ran rewrites his contact information and hands it over. The security guard looks at the sky outside the window and is stunned for a while before taking the page with his hands trembling.

Close the doors and windows of dormitory 414 and check the time. Su Yongchang will be out of class for a while, and the group will prepare to return to the office building.

"What are you looking at?"

Mo Xiaobei looked at Zhang Lei, who was hanging at the end and looking around, and asked curiously.

"I took a look at the Feng Shui of Xi Ruxiang and their dormitory."

Zhang Lei said mysteriously: "After my research, their dormitory door is facing the bathroom, and there is a toilet inside the bathroom, which brings bad luck.

There is no blockage on the north side of their floor. When the wind blows the filthy air, it passes through their dormitory halls. There is also a big tree in front of the window of their dormitory, and the sun cannot shine in. In addition, the living room is all girls, and the yin energy is getting heavier..."

"Don't you believe in science!" Xiao Ran turned around and said.

"I'm talking about science, but it's not thoroughly studied."

Zhang Lei said seriously: "This Feng Shui is actually a magnetic field, and the human body itself is also a magnetic field.

If the magnetic field in the surrounding environment conflicts with the human body's magnetic field, these magnetic fields will affect our senses, and we will feel some strange things. This is researched!"

...

The group returned to the office building, and the teachers in the office basically went out for dinner.

When he walked into Su Yongchang's office, a teacher sitting opposite Su Yongchang said that Su Yongchang had gone to the cafeteria and would be back before 12 o'clock.

Before long, Su Yongchang was indeed stepping on the spot and returning to the office.

Su Yongchang's hair was gray and his face was a little haggard. He held a tea cup between his hands, and the tea leaves inside swayed up and down with his pace.

"You, are you the police who come to Chase the Xiruxiang case?"

Su Yongchang looked at Xiao Ran and the other two, his eyes were a little dazed, and he sighed: "So young, I still remember the brother who came to investigate the case. He should have retired now..."

"People can retreat, but the case is always on the road."

Xiao Ran and others shook hands with Su Yongchang, then walked to the quieter conference room before sitting down.

"I heard that the recent corpse dismemberment case has been broken? How about it, is the murderer the one who harmed Xi Ruxiang?" Su Yongchang asked with concern just now.

“Sadly, not.”

Xiao Ran shook his head and saw that Zhang Lei had already adjusted the video, so he took out the portable record book and said, "But it is also because of this recent case that we have restarted the Xi Ruxiang case. Now let's find you to sort out the situation back then."

"It's so fast. It's been fifteen years in a blink of an eye. Many people should forget about this." Su Yong said long.

"At least we won't forget."

Mo Xiaobei said solemnly, "And you won't forget it. Teacher Su, have you ever complained about Xi Ruxiang?"

Su Yongchang was stunned and asked back, "Why do you say that?"

"Your future was interrupted by Xi Ruxiang. After all, the students had already gone to work. With the conditions at that time, you could not contact them often, but you were seriously wronged because of this..."

Mo Xiaobei said calmly, but his eyes always fell on Su Yongchang's face, observing every expression of Su Yongchang.

Su Yongchang smiled hoarsely and said bitterly: "It's all a thing in the past. Who made me her teacher? If something happened to the student, how can a teacher just care about himself?"

"Can you tell us again, fifteen years ago, what were you doing before and after Xi Ruxiang was killed?" Xiao Ran asked.

"certainly."

Su Yongchang held the teacup and said, "At that time, I was already a sophomore counselor. In addition to attending classes, I was also busy with daily affairs in the department. I read books at home on weekends."

"Always reading books at home?"

Xiao Ran recalled the inquiry records of Su Yongchang in the file. Su Yongchang replied that he accompanied his daughter to the mall and bought a frog-shaped doll.

"It seems that I have accompanied my daughter to visit the mall and bought some toys."

Su Yongchang thought about it carefully for a while and shook his head: "It's been so long, I can't remember it."

Xiao Ran nodded: "When Xi Ruxiang, do you still remember some of her life details when you came into contact with her?"

"Xi Ruxiang, what do you think, she always has a lot of worries, which makes people unable to see through."

Su Yongchang seemed to be trapped in the memories of the past and said slowly: "She is quite silent on weekdays, but occasionally she is very active. She always feels like she has a front and back..."
