In less than noon, the task assigned by Wu Long was completed, and he learned that Chu Xiongtong's girlfriend Twilight's real name is He Cuidui, an accountant of a foreign trade company, but he took a vacation a few days ago, saying that he was going back to his hometown in southern Sichuan, and now his mobile phone is turned off, and there is no other contact information.

After Wu Long heard this, he felt a little strange in his heart, thinking to himself, Dai Wenshang's girlfriend Mo Xiaole left for unknown reasons before he died, and now although it is said that He Cuiwan has broken up with Chu Xiongtong, but He Cuiwan is on vacation these days, is it just a coincidence?

A terrible thought suddenly rose in his heart? Could it be that He Cuidui took a vacation for another reason?

He hurriedly asked Ban Xing, the investigator who went to investigate the situation: "Does He Cuiwan have a leave slip when he asks for leave in the company?" ”

Ban Xing is Wulong's proud disciple, since he entered the serious case team, he has been valued by Wulong, and he has made two merits in three years, it is definitely not Wulong who gave him face, but Ban Xing's own efforts in exchange, Wulong asked him to investigate He Cuidu's matter this time, because he knew that Ban Xing would definitely find out the situation quickly and accurately.

Ban Xing scratched his head and said, "Yes, He Cuiwei asked for leave from the company's personnel department, and I made a copy of her leave slip back." ”

After Ban Xing finished speaking, he took out a copy of the leave slip from his briefcase and handed it to Wu Long, who glanced at it and said, "Then what do you think will happen next?" ”

Ban Xing put the leave slip back in his briefcase and said, "Next, I will contact the police station in He Cuidu's hometown in southern Sichuan and ask them to help me to see if He Cuidui has returned to his hometown, if necessary, I will go over in person?" ”

Wu Long shook his hand and said, "For the time being, let's contact the other party's police station, it's too time-consuming and laborious to go in the past, let's talk about it." ”

Ban Xing realized, he knew that he couldn't be too capricious in handling cases, and although the funds for handling cases were very sufficient now, if the case was not urgently needed, he would have saved as much as possible from long-distance attacks.

Ban Xing raised his eyes and looked at Wu Long and said, "Well, I'll try to check it first." ”

Wu Long hesitated for a moment and said, "Ban Xing, wait, not only He Cuidui, but also Mo Xiaole, you go and check it together, yes, find the common ground between them." ”

Ban Xing suddenly seemed to have a flash of inspiration and said, "Oh, I know, do you suspect that the murderer may be coming for these two girls?" If there is any intersection between these two girls, it may be the real motive of the murderer, right? ”

The expression on Wu Long's face turned from gloomy to clear, and said: "It's just a temporary idea now, let's check it first, it's still difficult to say." ”

Chi Ming didn't go to buy a large number of printers to come back for experiments, he knew that if he did that, Director Ba Fei might not necessarily agree, so he came to the Eastern Digital City alone, lingering in front of a printer repair shop on the fourth floor.

The shopkeeper saw a policeman walking back and forth in front of the store, with a panicked look on his face, and he said, "May I ask this police officer, is there anything wrong?" ”

Chi Ming stopped, he felt that there were many styles of printers on display in this printer repair shop, and there were also many dot matrix printers, so he replied, "Oh, where did you get these printers from?" ”

The shopkeeper hurriedly smiled and said, "You said our printer?" They are all sent by our customers for maintenance, and they are all some machines that are a little faulty, and they are worthless and worthless. ”

Chi Ming knew that the shopkeeper had misunderstood him, and he knew that the shopkeeper might suspect that the source of his printers was unknown, and that he might be suspected of selling stolen goods or something, so he immediately explained: "You misunderstood, I was trying to ask you for help." ”

The shopkeeper had a puzzled look on his face and said, "Looking for my help?" ”

Chi Ming said: "That's the case, I see that there are a lot of printers in your store, and I happen to have an experiment to do, and I want to print some samples through your printers and go back to study and study." ”

The shopkeeper seemed to finally let go of his worries and said, "No problem, I have a lot of printers in my store, you can call it." ”

Chi Ming entered the store, and the shopkeeper said, "You see that style you need, just say casually, I'll test it with you." ”

Chi Ming said calmly, "Okay, I'm going to try all the dot matrix printers in your shop." ”

The shopkeeper smiled: "Dot matrix printer? I'm the most expert in this, I have been doing printer maintenance for more than ten years, and I'm familiar with the new and old models. ”

Chi Ming suddenly thought in his heart, he came here to take a look, he understands the truth of selling charcoal, an old technician who has been repairing printers for more than ten years, his experience must be stronger than his own learning by doing, he said: "I see that there are at least a dozen dot matrix printers on the left shelf, do you want to give me a look in order?" ”

The shopkeeper said, "Okay, I'll get it for you." ”

The shopkeeper removed the first printer from the left shelf, expertly connected the computer, checked the driver, saw that the printer was ready, and said, "Do you have any requirements for the print?" Or just print one test page? ”

Chi Mingzheng hesitated in his heart, thinking that if he directly printed the original sentence "Let all the Creators end", in case the secret of the case was leaked, it would be really troublesome, so he said: "In this way, you open Word, I will enter the printed content, you just need to help me stuff A4 paper." ”

The shopkeeper clicked on Word, and Chi Ming began to type the characters "Let's end up and make the final master" on the dilapidated keyboard, which was actually the original words he had shuffled out of order in his mind, so that he could not only observe the printing effect of each character, but also prevent the leakage of case information.

After he has typed in the characters, set the font and size, and the shopkeeper has put the paper away, he clicks the "print" button, and the printer "squeaks" and starts printing.

After printing it out, Chi Ming began to look at the handwriting in the order in his mind, he felt a little dazed, thinking that the result of this printing looked almost no different, and he didn't know if his stereo microscope would come in handy after going back, it was difficult to say.

Seeing Chi Ming's sad face, the shopkeeper asked, "What?" Is there something wrong? ”

Chi Ming sighed and said, "No, I see that the effect of this printer seems to be similar." ”

The shopkeeper smiled: "This you are a layman, if the laser printer printing effect is really difficult to distinguish, but this dot matrix printer is different, starting from the beginning of the 7-needle print head, the development of the current common 24 needles, no matter how fine it is, it is defective, each word is a collection of the points of these printing needles, and insiders will understand it at a glance." ”

Chi Ming didn't wait for the shopkeeper to finish speaking, so he hurriedly asked, "You said that you can see which printer the printed words are?" ”
