Guan Zheng smiled and said: "Then I am afraid you will be wronged. Let's stay here for a while. We need to check it out before considering what charges you will be charged."
"You guys do whatever you want, but please show evidence."
"Of course, you won't be disappointed."
Guan Zheng came out of the house calmly. Xu Jiuyan looked at Guan Zheng and said, "Can you sue him for murder?"
"I don't know, let's take one step at a time. Don't be emotional, maybe it's really suicide."
Xu Jiuyan nodded and said, "I hope there will be new evidence."
"There must be. Go, go to Guan Nuo and see how the password is."
Guan Zheng walked into the office, Guan Nuo was very busy.
Guan Zheng sat down and said, "How is the password broken?"
Guan Nuo shook his head wearily, and said, "No results. I tried all the passwords but couldn't get the proper plaintext. I suspect that this password has a unique meaning and points to the codebook."
Guan Zheng took the string of numbers, thought for a while, and said, "Go find this barcode."
"Barcode? How do you know this is a barcode?"
"The things that Chang Yuxin can access are limited, because Chang Yuxin's external contacts are limited, and it is impossible to memorize commonly used passwords, so this string of passwords may not have a deeper meaning, then it may only be the books he came into contact with. Or the bar code of pens and related items."
Guan Nuo clicked and voted, and quickly entered this string of passwords into the computer. Guan Zheng watched the results appearing on the computer. It was the Nanyi version of the ninth grade Chinese textbook.
Xu Jiuyan asked, "How do we find this? Zhang Yuxin's copy has been destroyed!"
"You don't need to find the original, just follow this barcode and get a copy of the same batch back."
Guan Nuo asked: "Then where is the password? We only have a password book now."
"Check the letter from Zhang Yuxin, there must be a password."
Guan Nuo unfolded the letter and said: "I have checked this letter with Old You with a document detector. There are a few very small dots on it, like compasses and name tags."
Guan Zheng looked at the family letters with a magnifying glass and said: "This letter contains more papers, which means that his password content should be more. Although this will bring us difficulties, the deceased provided it. There will be more first-hand evidence."
"But brother, did you know that this Chinese textbook plus the preface has a total of 28 pages."
"It's best to find the specific page number from the family book. If it doesn't work, you can substitute it into the cipher book. You must know what information Chang Yuxin sends to your home."
Xu Jiuyan pointed to the advertisement number at the bottom corner of the letter paper and said, "Will the page number clues be placed here?"
Guan Nuo looked at the phone number carefully, but didn't see anything. Guan Nuo had no choice but to say: "I'll use the document detector to test it later."
Guan Zheng pulled Xu Jiuyan up and said, "These things are not yours. Leave them to Guan Nuo. You will go with me, and then go to Instructor Yang for tea."
"OK!"
Guan Zheng and Xu Jiuyan arrived at the school. Director Liang saw Guan Zheng as if he had seen an enemy, and said with an aura: "What are you doing again?"
"I'm coming to instructor Yang."
Director Liang said: "He took a leave of absence and hasn't come for several days."
"Ask for leave? When did it happen?"
"Just after you took him away last time, he just came back to ask for leave."
Guan Zheng didn't expect to rush for nothing, and said, "Do you know the address of his house?"
When Guan Zheng arrived at Instructor Yang's home, no one was seen. Only instructor Yang's children were at home.
Guan Zheng asked: "Where are your parents?"
The child said: "Dad came back once a few days ago, and mother returned to his hometown."
"Can you write me mom's phone number?"
Guan Zheng took the phone number of Instructor Yang's wife and called out. Instructor Yang's wife rushed back soon.
Guan Zheng asked: "Where did your husband go?"
"I don't know. A few days ago, he said he would take our wife to move. I said how to move in a good manner. He told me not to ask. Then he answered the phone and went out. I heard him say a million , I don’t know what he is doing."
Guan Zheng came out of Instructor Yang’s house and called Yangzi: “Check instructor Yang’s call records and locate instructor Yang’s cell phone by the way.”
Yang Zixun entered the number into the computer and said, "I found it. The last call was from Principal Li. As for the location of the phone, it's a bit strange."
"Headmaster Li's house?"
"I'm going, are you a god?"
Guan Zheng hung up the phone and said, "Go to Principal Li's house."
When Guan Zheng and Xu Jiuyan arrived at President Li's house, they knew what a rich man's life was.
A villa with a garden, European-style architectural style, and magnificent decoration, you can see that it is a waste.
Guan Zheng looked at Mrs. Li with an arrogant face, a little hairy, and said, "Mrs. Li, hello, I want to ask you a few things about President Li."
"Police officer, our old Li is a legitimate businessman."
"Uh, I know, I want to ask him if he has done anything unusual recently?"
Mrs. Li looked at her long fingernails and said, "Of course not. It's just that he hasn't been home for a few days. He usually does it too, often socializing or something."
Guan Zheng said: "It's not for entertainment that he didn't go home these days."
"what is that?"
"He is in our bureau."
Mrs. Li was anxious: "What do you mean? What's wrong with Lao Li? Why are you arresting him?"
"We suspect that he is related to a suicide case."
"You also talked about the suicide case. Who can stop people if they want to die?"
Guan Zheng admired Mrs. Li's meanness a little, and said: "Have he brought anything back recently, or took out something?"
"No."
"you sure?"
"This is my house, can I not know what is missing?"
Guanzheng came out almost ashamed. Xu Jiuyan looked at the colorful flowers in the back garden, and said, "Look at that other's house, you are about to catch up with the emperor."
Guan Zheng followed Xu Jiuyan's gaze, and the flowers bloomed well, but what's wrong there
"It's the lawn!"
"Lawn? What happened to the lawn?"
Guan Zheng ran over and said, "This lawn is different from the others. The grass is lighter in color, but the surrounding colors are denser, indicating that this piece of lawn is newly planted."
"Such a large piece is definitely not a small object buried."
"Call in Yoko, let him bring a search warrant, Xiao Huan'er and Lao You."
Xu Jiuyan stared wide-eyed and said, "You mean, instructor Yang is here?"
"I didn't say, take precautions before they happen!"
Mrs. Li looked at Guan Zheng and Xu Jiuyan studying the lawn through the glass upstairs, and her heart suddenly became suspended. (End of this chapter)
