Although Deng Ru and Ding Yiran are young, they have left the campus for many years. Today, walking on the beautiful campus of Zhongjiang University, watching young students who are often dressed in fashionable clothes, I can't help but feel a little emotional.

"It's better to be when I was in school. I missed those times now." Ding Yiran said walking on campus like a student girl with his hands on his back.

"I miss you, then you often come and visit with nothing, maybe you can meet by chance." Deng Ru and Ding Yiran joked.

"I'm not afraid, if you have it, just have it. But you have to be careful, be honest, don't tell my sister-in-law." Ding Yiran said with a small mouth, not showing weakness at all.

"You are not afraid, I am not afraid. Your sister-in-law can believe in anything, but she doesn't believe that I will have time to meet him." Deng Ru could handle Ding Yiran's malicious reminder calmly.

"Let's go quickly, Brother Deng, the building in front should be the building of the Department of Mechanical Engineering."

Zhongjiang University's mechanical design and manufacturing major is a nationally renowned major. Those who can enter Zhongjiang University and be admitted to the mechanical design and manufacturing major are all students with excellent academic performance. Deng Ru and Ding Yiran are not familiar with mechanical design and so they asked around on campus before they knew they were going to the Department of Mechanical Engineering.

There was only an elderly female teacher working in the department office. Although the female teacher was older, she looked very neat. Ding Yiran and Deng Ru walked in without affecting the female teacher's typing speed. Only crackling keyboards could be heard in the quiet office.

Ding Yiran walked to the female teacher and said:

"Hello teacher."

The female teacher looked at Ding Yiran from above the reading glasses, looked down at the computer screen and asked:

"Little girl, what's wrong?"

Because they both wore casual clothes today, it seemed that the female teacher regarded Ding Yiran as a student, and Deng Ru covered her mouth and held her smile.

"Teacher, we are from the Municipal Police Department." Ding Yiran took out his ID and walked to the female teacher.

"What?" the female teacher raised her head, took off the glasses from the bridge of her nose, and asked in confusion.

"Teacher, we are from the police station, come here to learn about the situation." Ding Yiran handed his ID to the female teacher to see.

The female teacher put on her glasses again, took Ding Yiran's ID and looked carefully, then made a surprised expression and said:

"Oh, you really belong to the police station. Hahaha, I treat such a young girl as a student in the department."

"Teacher, are you your surname?" Ding Yiran asked.

"No need to be expensive, no need to be expensive, just call me Teacher Wang." Teacher Wang said kindly.

After Ding Yiran and Deng Ru explained the purpose of the female teacher, the female teacher said in a difficult manner:

"Oh, the 1997 graduates have been so long. I wonder if I can find the graduation files at that time."

After hearing what the female teacher said, Ding Yiran quickly said:

"Teacher, you have been here for so many years, so you should have an impression."

"You guys, that is, if you meet me, you may not be able to find any young teachers. Let me think about it.

Teacher Wang picked up the teacup on the table and took a sip of water. He looked at the swaying leaves outside the window and thought for a while. He suddenly slapped his hands and said with a smile:

"I remembered it. When I moved in the department last time, I put all the information retained by graduates in a cardboard box. The cardboard box should still be in the inner room of the information room."

"That's great. Teacher Wang's memory is really good." Ding Yiran said happily.

"But you have to go and help, there are a lot of things in the information room."

"No problem, no problem. With a big man here, you are not afraid of anything." Ding Yiran pointed his hand at Deng Ru and said.

"Well, yes, the big guy has strength." After saying that, Teacher Wang took out a bunch of keys from the drawer and led Ding Yiran and Deng Ru to the information room.

Deng Ruyi entered the information room and thought it was still very neat, so there were no cartons. Rows of data cabinets were arranged neatly, and the labels on the glass cabinet doors were also standardized. The data boxes in the cabinet filled the space in the cabinet.

"Don't look at it's pretty good, the information we're looking for is not here." Teacher Wang led them to find a small door in a corner of the information room and opened it with an inconspicuous key.

"Wow." It was Ding Yiran's turn to exclaim. Inside this small door was a small room of more than a dozen square meters, with cartons of large and small, as if it was a warehouse of cartons.

"How is it? I saw it. The big guy has a place to use it now." Teacher Wang said with a smile.

Under the command of Teacher Wang, Deng Ru brought up the cartons filled with information one by one, and then moved them up. He opened the cartons and searched for them, and then put the piles of information he took out. There was no air conditioner in the hut and it was not ventilated. Deng Ru and Ding Yiran were sweating profusely after a while.

"What do you think, do you want to take a rest?" Teacher Wang didn't go to move the cardboard box. She sat on one of the cardboard boxes and directed, but she was also sweating profusely.

"It's okay, Teacher Wang, if you are tired, go to the office to cool down for a while, and we can do it ourselves." Ding Yiran quickly said to Teacher Wang.

"I'm fine. As long as you are not tired, then continue looking for it." Teacher Wang grabbed a stack of documents and fanned the wind as a fan.

Hard work pays off. After Deng Ru's back was soaked in sweat, he finally found the registration form for the 1997 graduates in a dusty cardboard box.

Deng Ru took out a large stack of documents from a full pack of kraft paper bags, and found the graduation registration form for the 1997 mechanical design and manufacturing major. There were 120 graduates in this class of mechanical design and manufacturing major, and these students belonged to three classes, namely Design Class 9301, Design Class 9302, Design Class 9303, and each class had 40 students. Ding Yiran found Tian Shan No. 12 and Meng Yuanming No. 29 in the list of Design Class 9301.

"They are indeed from the same class," said Ding Yiran.

"Who is in the same class with whom?" Teacher Wang also came to watch the fun.

"Tian Shan and Meng Yuanming." Ding Yiran pointed to their names and said.

"This Tian Shan is a girl, there are not many girls in our mechanical engineering department, and there are only three or five students in a class at most." Teacher Wang said with emotion.

"Teacher Wang, do you have any impression of them?" Deng Ru asked.

"No, no. I can't remember so many students!" Teacher Wang waved his hand to answer.

"Teacher Wang, can we take these lists to copy them?" Deng Ru asked.

"Yes, yes, I have a copy machine in my office."

Teacher Wang enthusiastically sent Deng Ru and Ding Yiran out of the office, and did not forget to remind them to come to her if they had anything to do. Ding Yiran turned around and looked at Teacher Wang who was waving at them. The attachment to the school and the teacher in his heart surged into his heart again.

When they returned to the bureau, the work of interrogating Xie Yuan again was in progress. He Xiaohui and Xiao Wang were fighting wits and courage with Xie Yuan in the interrogation room, while Su Le and Zhang Pengfei were nervously staring at the situation inside the interrogation room.

"How is the situation?" Deng Ru asked.

Su Le shook his head and said:

"Not ideal, Xie Yuan seems to be hiding many things, but he just refuses to say them."

"Not afraid, we bring a bombshell, let's see if he can do it." Deng Ru turned around and entered the interrogation room.

Deng Ru walked to He Xiaohui with the information copied from Zhongjiang University, whispered a few words in her ear, and then walked out with a smile.

He Xiaohui flipped through the information in front of her, tapped the table with her fingers, stood up and walked to Xie Yuan's side. She possessed her body and stared at his eyes and said:

"Do you know Meng Yuanming?"

Xie Yuan's body vibrated when he heard the words Meng Yuanming. He lowered his head and thought for a while, then raised his head and looked at He Xiaohui and said:

“Don’t know.”

"I know you will say you don't know, but it doesn't matter. Someone knows Meng Yuanming, and the relationship is not ordinary." He Xiaohui said with a smile.

Xie Yuan's body trembled again, but the time for bowing his head this time was obviously much shorter. He raised his head and said calmly:

"I don't understand what you're talking about."

"I think you don't understand, but you're pretending to be confused."

"I don't know Meng Yuanming, it doesn't matter if others know each other or not."

"But if someone knows you, it has something to do with you." He Xiaohui continued to keep an eye on him.

"Who?" Meng Yuanming fell into a trap.

"Tian Shan." He Xiaohui replied.

Xie Yuan's reaction to Tian Shan's name was not the same as He Xiaohui thought. He answered very calmly, just like he had already thought about how to answer in advance:

"I may not know all the people Tian Shan knows."

Seeing that Xie Yuan was still very psychologically prepared, He Xiaohui could only disclose further information:

"We went to Zhongjiang University today and found that Meng Yuanming and Tian Shan were college classmates."

"Oh, everyone has college classmates, and I have them too."

"Xie Yuan, you still refuse to explain?" He Xiaohui asked.

"I have nothing to explain, I didn't kill anyone." Xie Yuan replied.

"Okay, since you are unwilling to take the initiative to explain, let me tell you for you. Meng Yuanming and Tian Shan are college classmates. You found that their shops were actually open on the pedestrian street, so you began to suspect that there was something wrong with them. You followed them and discovered the fact that they committed adultery, so you decided to kill Meng Yuanming." He Xiaohui could only use this kind of guess to force Xie Yuan to tell the truth.

"Hehehe." Xie Yuan smiled bitterly and did not answer He Xiaohui, but his attitude had already shown his disdain for He Xiaohui's statement.

"What? Do you think the plot is not exciting enough?"

"Enough! I won't allow you to insult my wife." Xie Yuan suddenly burst out with anger.

"Okay, since you care so much about your wife, then tell me why you don't even know the classmates who opened the store with her?"

"There is nothing reasonable in the world. If you don't know, you don't know. Don't force me to admit to killing someone." Xie Yuan returned to his calmness. He looked at He Xiaohui in a hurry and said.

"It doesn't matter whether things in the world are reasonable or not, what matters is justice. No matter how well criminals disguise themselves, they can't escape the judgment of justice in the end." He Xiaohui glared at Xie Yuan and said.

"I am looking forward to a just judgment." Xie Yuan's eyes met He Xiaohui's gaze without fear.

"Well, since you plan to be stubborn, let the facts speak and take him back to the guard room."

He Xiaohui walked out of the interrogation room. When she passed by the door of the observation room, she saw Su Le and the others watching, and couldn't help but shout:

"What are you looking at? Have a meeting!"
