After casually eating fast food, Wei Kai and I drove to the agreed restaurant, glanced at our watches, and it was 15 minutes earlier than the agreed time. Wei Kai opened the window of the car, sprayed himself with perfume by the way, and began to rummage through the large and small bags he put on the car, and finally found a bottle of long-tube perfume for me: "Spray it." "Wei Kai helped me open the cap.

"What?" Although I was puzzled, I still sprayed Wei Kai's words a few times.

Weikai's expression eased at this time: "The taste of fast food on the two of us is too strong, I'm afraid that I will be thrown out by the waiter in a while." ”

"Boom." I complained about him, but I have to admit that Wei Kai is careful, maybe Zhang Minghe and the restaurant won't mind the taste of fast food on us, or they won't show it, at most they silently despise us in their hearts, but if the entrusting party puts eyeliner around, then how to judge this matter will be another matter.

"If we ask them about what we smell on, it's probably not good for our eyeliner. I'm not a good person, but I don't want too many unrelated people to be involved, we just go to investigate the clues, and we don't want to get into favors anymore. Wei Kai looked in the rearview mirror to straighten out the hairstyle that I had just messed up.

The car was filled with the smell of pine wood on Wei Kai's body, and as soon as the appointed time came, Wei Kai and I walked into the restaurant, probably I was suspicious, and I had arrived at the restaurant, I felt a tense atmosphere, a waiter came over and asked if we had booked in advance, and after getting the denial, the waiter looked around and asked what kind of location we wanted. Originally, I wanted to say that the top is a quiet place inside, but it was not opened, but I insisted on the position by the window.

"I'm sorry, sir, the window seat has already been booked, and we really can't arrange it for you." The waiter said politely, but the rejection in his tone was unmistakable.

"But I just want to sit by the window, and I can wait until you close." Wei Kai insisted.

The waiter couldn't convince us for a while, so he said wait and arranged us in the waiting area for the time being. "Why do you insist so much?" After the waiter walked away, I asked Wei Kai in a low voice.

Wei Kai looked at the direction the waiter left: "Although I'm not sure if the client has arranged eyeliner here, sitting in front of the window will always be a very suitable route to escape." If we're in there, I can't get you out of here safely. ”

A few minutes later, the waiter led us to the window and said that Manager He had coordinated it temporarily. Walking into the main hall and seeing someone secretly peeping at us, I pinched Wei Kai's arm, Wei Kai just smiled and comforted me not to be nervous, and sat generously next to the floor-to-ceiling window.

The waiter politely brought two glasses of water, but neither of us touched it, and after more than ten minutes, Zhan Guangming walked in with a bad face. "Sorry, there was some traffic jam on the road, I thought it would be faster to take a taxi."

I shook my head and said I didn't mind, "What do you want to eat?" ”

Zhang Ming said that we had a light meal at the taxi because we just wanted to ask him some questions, so there was no need to be pretended. It's almost nine o'clock in the evening, and it's an early winter night, and the blow is not very willing to stay outside too much, and there are not many people eating in the restaurant, even if they only order three drinks or desserts, the restaurant doesn't mind very much. Zhang Ming ordered a bottle of cheap red wine and asked us what we wanted to know.

Wei Kai wiped the cup with the tissue he carried, and then poured half a glass of red wine for me and him, Zhang Ming immediately understood our thoughts, and he didn't say anything, just took a sip of the wine in the glass before us, signaling that there was no problem in our drink: "They asked me just now." Zhang Ming controlled his volume, "They told me not to believe you, but they didn't tell me the reason, but because you told me the truth in advance, I still decided to believe you." Can you tell me what happened to Ding Yuan now? ”

"The result of our tentative investigation is that he took the company's money and absconded with the money. That money wasn't very clean, though. So the company didn't report to the police, and according to our investigation so far, in the past two years, he has also assisted the company in money laundering and made a lot of profits, so his company is now dragging us to track him down. ”

"Impossible." Before Wei Kai could finish speaking, Zhang Ming suddenly interrupted Wei Kai's words, "It's impossible for Ding Yuan to do such a thing. Probably realizing that his volume was too loud, Zhang Ming immediately lowered his voice and emphasized to us.

"However, our investigation is not what you think, but let's not dwell on what kind of person he is. Dingyuan has been missing for almost a month, and we have checked his phone, and you were his last contact a few hours ago, so I want to know what he said to you during your last call, did you mention that someone was trying to hurt him? ”

Zhang Ming shook his head: "No, the last time I called, he was still very happy, the Hayer group and I had dinner together this month, but after a week, when I called to make an appointment with him, he neither hindered nor answered the phone." I thought he was busy, so I didn't pay attention to it, and then you called me and said that you wanted to know about Ding Yuan. ”

Wei Kai shook the glass in his hand, the red alcohol appeared in the light of the restaurant, and the shadow refracted like a jewel, Wei Kai stared at the liquid in the cup and asked Ding Yuan, who was sitting opposite: "Because you are the only person in Ding Yuan's contacts who has no contact with his business, that is to say, you are the only person in Ding Yuan's contact who relieves his troubles and pressure." Since this is the case, I want to ask you, has Dingyuan usually complained to you about things in his company? ”

Zhang Ming shook his head without thinking about it: "No, he hasn't complained about things in the company, no, he hasn't said anything about his work." ”

He was lying, this was my first reaction after listening to his answer, in addition to the steps on his expression and the trance in his eyes, his repetition of Wei Kai's question also revealed that he was lying, it seems that Ding Yuan must have said something to him. But I don't know if it's because of the threat from the entrusted party, or if he wants to help Ding Yuan keep the secret, in short, he doesn't want us to know too much about Ding Yuan.

"If you think about it again, Dingyuan regards you as his only friend, has he ever mentioned anything special about his company to you? You know, people are used to complaining about their surroundings. I hope he can tell me some useful clues, even if it's just a little bit.

But Zhang Mingtie was determined not to reveal any secrets about Ding Yuan to us, and his eyes subconsciously glanced around him: "He really hasn't mentioned it to me, even if it's a friend, not everything can be shared." His expression was unusually determined, and it seemed that we couldn't ask anything today.

Looking at his vigilance around him, it is very likely that he not only wants to hide it from us, but also fears that what he says to us will be monitored by the client and will bring more danger to his friends and himself. His forehead was already covered with beads of sweat, and the heating in the restaurant was not very sufficient, and he could be covered in sweat in this not very warm place, which showed how nervous he was now.

He looked at us, his eyes rarely blinked, and he was careful to breathe. After we had eaten cautiously, Wei Kai proposed to go home, but before leaving, Wei Kai said: "By the way, as for the cooperation with your bank, my friend will help me follow up, and our cooperation fee should not be lower than the bid of the customer who found you today." Wei Kai said this in a loud voice, as if he wanted the restaurant to make a profit for everyone to hear.

I glanced around and noticed that except for a few diners who were eating, they looked at us like aliens, and the few others who seemed to be eating did just bow their heads or turn their faces in other directions instead of paying attention to us. After that, Wei Kai and Zhang Ming shook hands and said goodbye. Zhang Ming rejected Wei Kai's offer to send him home, and after politely waving goodbye to us, he walked in the other direction.

When we went out, the car that was not driven did not come out of the parking space he had just parked, and I stared at Wei Kai in surprise: "Your car is gone." ”

"Don't worry." Wei Kai shrugged his shoulders, "I asked someone to help me drive away, in order to prevent some shrimp soldiers and crabs who don't have long brains from putting messy things in my car, I asked people to help me drive the car away in advance, so now there are two choices, either go to the neighborhood to find a home to have supper, or let us take a taxi home directly." But I think it's better to eat something to warm up, the restaurant was a bit too deserted. Wei Kai seemed to be asking for my consent, but in fact, he was just saying these words to a few seemingly idle people passing by.

I smiled at him and approved of his first offer.

"I know there's a tavern around here that has a good late-night snack, and the owner is my friend, so you can get half the price." Wei Kai pulled me into the depths of the night.

The owner is an old, dark-skinned uncle who greeted us when he saw us come in, so he rolled up his sleeves and went into the back kitchen. Wei Kai took two bottles of beer directly from the bar: "Do you want to drink?" Wei Kai asked me after opening two beers.

I nodded, the heating in the noodle shop was on so much that I didn't feel any cold at all wearing only my shirt.

The boss brought out a plate of kimchi and a plate of peanuts and went back to the kitchen. The boss's sleeves did not hide the tattoo he carved on his arm, and the small screenshot that was leaked showed that the tattoo on the boss's arm looked like a dragon

"Take it out." I stretched out my hand to Wei Kai, "The cooperation you just mentioned is to distract the attention of those eyeliners that the client has placed in the restaurant, so as to buy time to get information from Zhang Ming. Zhang Ming should have given you the note you had already written when you and I received it, right? ”

"You see?" Wei Kai asked me with a frown.

"I guessed it." Although I didn't see it, I knew that there must be fraud in Wei Kai's slightly abnormal behavior at the end, "You don't like Hebei people to have physical contact, so no matter who you are, including Director Mao's case that first caught my attention, you are very repulsive to physical contact, and you can shake hands with others, which seems to be ordinary, but it is intimate and abnormal for you, which means that you can get more benefits than the action itself." Moreover, you must not make a gesture of rejection after shaking hands with him, you are not a person who can hide your emotions, according to your habits, you will directly dislike where to go to wipe your hands with a handkerchief, but you don't. You haven't done anything since that that suits your normal personality, which only tells me that you have something in your hands. You must not endure the discomfort and hide the facts. After that, you proposed to come here, and the store you often came to was to alleviate the discomfort in your heart caused by the actions of different Xuchang. I didn't see anything, but I know you, so I can guess what must have happened at the end that made you so nervous, so unusual. Okay, since you can't hide it from me, tell me what Zhang Ming gave you? ”

At this time, the boss came over with two bowls of beef noodles, put them on the table, and saw that I had been staring at his arm, so he smiled and rolled up his sleeve to his big arm; "It's Jair, the second of the nine sons of the dragon. Eat it quickly, the noodles will be lumpy when they are cold. ”

"The boss has changed rivers and lakes before." Wei Kai smiled, and the boss sat behind the bar and laughed without saying a word.

"So, what clues did Zhang Ming give you when he shook hands with you?" I still haven't forgotten what I just saw.

"Fill your stomach first." He didn't mean to share the secret with me right away.

After snoring and eating the beef noodles, we continued to eat kimchi and drink beer, and at this time, Wei Kai took out a piece of chewing gum that Zhang Ming gave him when shaking hands from his pocket.

, the information is revealed after peeling off the gum, and only a few boys are written on it, because the paper area is limited, so the clues are also written concisely.

"I should have written it in a hurry." Wei Kai looked at the scribbled handwriting on the paper and said, "The client doesn't trust him very much, so it should have been just at the scene, after opening the door of the small room, he was directly sent to the restaurant, and he was monitored all the way, so the note should have been written for us in the minutes before opening the fire door." After that, I re-packed the gum and came with them. It is estimated that the client did not guess that he would tell us the clues in this way, and only considered the possibility of telling us in person, so he survived. I have to say that Zhang Ming, this kid is still quite brainy. ”

With the help of the lights in this store, we began to study the text on the slip of paper: electronic payment systems.

"I remember that the information on your mobile phone drop shows that Ding Yuan was not an employee of the sales department at the beginning." I remembered the materials I carefully studied in the afternoon, Ding Yuan graduated from the computer engineering department of a very good university with a master's degree, and when I first knew about this network company, the position was a background program maintenance engineer.

"That's right, I am a classmate of the same major as Zhang Ming. Electronic payment system? Sounds like the knowledge they would be involved in their profession. Wei Kaimo clutched the candy wrapper.

"Electronic payment systems." I said silently in my heart, and suddenly, I raised my head, looked at Wei Kai and said; "Wei Kai, if it is a payment system, in addition to engineers, the most common contact with this system is the company's financial department, if you link this clue to your previous investigation, it may be possible to secretly transfer the company's funds to your own private account without going through the financial department." Finally, one of the doubts was solved. But my eyes unconsciously turned to the boss uncle who was sitting behind the palm of his hand.

Wei Kai looked at my nervous appearance and suddenly smiled: "Don't worry, my own people." ”

The uncle seemed to feel that our eyes were focused on him, raised his head and pointed to his ear and waved his hand, telling us that he didn't hear anything at all, I put my mind at ease and said to Wei Kai: "If the key lies in this electronic payment system, and Zhang Ming, as a friend, can provide this as a clue to us, it means that this payment system is not something that Ding Yuan only appeared after he joined this company." ”

Wei Kai agreed with me, and I went on to put forward my own speculation: "Ding Yuan and Zhang Ming both studied computer engineering in college, and their research directions are computer programming applications, and the electronic payment system is within the scope of their studies, could it be that this system made Ding Yuan an accomplice of the client?" ”

"Quite possibly." Wei Kai nodded in agreement, "When I investigated the relationship between the two people, I found that they collaborated on their graduation project when they were in college. However, it is not an electronic payment system for the conversion of funds, but it is very similar. Their graduation project is to help create a firewall similar to a bank or a large company's website to help these customers prevent hackers from maliciously tampering with account names and account transaction records. ”

"If they're looking at how to stop hackers from tampering with transaction records and account information, it's going to be very easy for them to understand how to be a hacker who can get in and out of the firewall without leaving a trace, right?" Hearing the meaning of Wei Kai's words, I once again made a bold guess about the salt of the two: "In fact, from the very beginning, this company decided to hire a quota because of his talent, but the initial idea was just a test for him. After that, an opportunity was created to pull him into the gang. And in the experiments again and again, Ding Yuan kept going to his old classmate and friend Zhang Ming to perfect his hacking skills. ”

Wei Kai smiled: "That's right, so what role Zhang Mingai played in this commission, we can't make a conclusion for the time being." Maybe at first we thought that Zhang Ming had nothing to do with Dingyuan's commission, but when the party constitution gave us this clue, I had to rethink Zhang Ming's role in this case. First of all, as you analyzed, since Zhang Ming was able to provide us with the clue of the 'electronic payment system', it shows that he is not ignorant of the experience of low-cost plans. Very few people will repeatedly mention the previous graduation project after graduation, don't forget that Ding Yuan and Zhang Ming have stable jobs, they don't need to work hard for their graduation projects, you know the code farmers in order to reduce mental consumption, they just focus on their work as much as possible, and then will not discuss too much design professional information. However, if they can take the trouble to use the time they can contribute to discuss their graduation project, it shows that the temptation of this design is far greater than the fatigue itself, and if we continue to speculate along this line, I believe that Zhang Ming himself and Ding Yuan's disappearance, as well as his previous absconding with the money, are also inseparable. ”

"And." I followed Wei Kai's train of thought and said: "However, Wei Kai's abnormal disappearance made Zhang Ming alarm in his heart, maybe Ding Yuan touched the bottom line of the instigator behind the scenes, and was killed to remind Zhang Ming like a monkey; In other words, the mastermind behind the scenes wants to unload the mill and kill the donkey, but in either case, I believe that Ding Yuan's disappearance has made Zhang Ming, who is also involved in the research of this 'electronic payment system', feel uneasy. Since he is also one of the designers, he can naturally detect that Ding Yuan did not touch the funds in his account, and he can guess that Ding Yuan may have encountered some kind of accident, so after receiving your call, he found that Dingyuan's account still did not move after two weeks, and finally made up his mind to ask you for help, but what he didn't know was that the other party had already been eyeing his whereabouts, so that after he took the initiative to contact you and ask you for help, he should have suffered some kind of threat, making him more aware that he was in danger. That's why he needs our help even more. Therefore, this note in your hand is not a simple clue, it is more like a distress note. ”

Wei Kai looked at the gum wrapper in his hand and raised the corners of his mouth slightly; "In this case, can I understand that Zhang Ming has temporarily joined our camp?"

I also laughed: "It's hard to say, Zhang Ming is just worried that his life may not be guaranteed, and he temporarily threw an olive branch to us, maybe in the end it will be backwater, and it may not be necessary to turn back in the end, when he can save his life, he will be worried that the electronic payment system designed by him and Ding Yuan will attract the attention of the police, and all the profits he and Ding Yuan have made with the help of this system are evidence that he was prosecuted for theft and fraud." However, none of us know if his help to us today was a bait for her to collude with the client in private to lead us into a trap. He has now won the 'five-in-a-row' double kill, and no matter which way he goes, it will be a win for him. ”

"We've run into a double agent. The one I hate the most is a double agent. Wei Kai smiled and grinded his teeth.

"Hee-hee, so am I." I grinned, "So what are we going to do?" You can't be led by the nose, right? I smiled and waited for Wei Kai's decision. (To be continued.) )
