Instructing her daughter to practice throwing knives, the police were frightened and asked to file

Liang Fei's heart moved, and he asked: "Do you still have these devices now?"

Li Qiang gave a bitter smile: "He took it back a long time ago. I don't have any evidence in my hand now. I only have some chat records and transfer records with Liu Si."

As he spoke, he took out a mobile phone from his pocket and handed it to Liang Fei: "This is the mobile phone that Liu Si and I use to contact each other. It records all our chat content and transfer information. You can take a look."

Liang Fei took the phone and looked through it carefully. He found that the chat records between Li Qiang and Liu Si did involve many illegal acts, including theft, extortion, and even murder! The transfer records also showed that Liu Si did receive a large amount of funds from unknown sources.

He took a deep breath and handed the phone to Qin Tian: "Mr. Qin, take a look."

Qin Tian took the phone, quickly glanced through it, and then nodded: "These evidences are enough to prove that there is indeed a mysterious big boss behind Liu Si who is manipulating him to do bad things. And judging from the transfer records, this big boss should be quite rich and powerful."

Liang Fei agreed: "That's right, we must find this big boss as soon as possible and bring him to justice!" He turned to Li Qiang and asked, "Are you willing to cooperate with our investigation and help us find the identity of this big boss?"

Li Qiang nodded without hesitation: "I do! I have wanted to get rid of him for a long time, but I never dared. Now that Liu Si has been arrested, I know that if I don't speak out, I will be the next one to suffer."

Liang Fei nodded with satisfaction: "Very good, then tell us all the information you know about this big boss now, don't miss any details."

Li Qiang began to recall carefully and told Liang Fei and Qin Tian everything he knew. He described how the big boss contacted them through the Internet and phone, how he issued tasks, how he paid them, and how they destroyed the contact equipment. He also provided some possible clues, such as the big boss's voice characteristics, accent, and some special language habits.

Liang Fei and Qin Tian listened very carefully, interrupting from time to time to ask for some details. They knew that this information was crucial for the subsequent investigation.

After Li Qiang finished speaking, he looked at Liang Fei with some trepidation: "Officer Liang, I have told you everything I know. Can you protect me? I am worried that the big boss will send someone to retaliate against me."

Liang Fei solemnly promised: "Don't worry, we will ensure your safety. You will live in the police station now, and we will arrange people to guard you 24 hours a day. When this case is closed, we will give you a new identity and let you start your life again."

Li Qiang was very grateful when he heard this: "Thank you, Officer Liang! Thank you!"

Liang Fei waved his hand: "You don't have to thank me, this is what we police officers should do. You should have a good rest now, we will find out the identity of this big boss as soon as possible."

After that, he turned around and asked Qin Tian: "Mr. Qin, what do you think we should do next?"

Qin Tian pondered for a moment and said, "I think we can start from two directions. On the one hand, we can try to track the big boss's network identity and phone signal based on the clues and information provided by Li Qiang to see if we can find his real identity and location. On the other hand, we can start with Liu Si and see if we can get more information about the big boss from him."

Liang Fei nodded: "Mr. Qin is right. Then let's split up. I will arrange for the technical tracking police officers to tell them the clues and information provided by Li Qiang and ask them to start tracking immediately. You go and see if there is any new progress from Liu Si."

After the two discussed it, they immediately started to act. Liang Fei went to find the police officer in charge of technical tracking, told them the clues and information provided by Li Qiang, and asked them to start tracking immediately. Qin Tian came to Liu Si's ward again.

Seeing Qin Tian coming in, Liu Si's eyes flashed with panic and uneasiness: "What are you doing here?"

Qin Tian smiled slightly: "Liu Si, don't be nervous. I'm here to help you."

"Help me?" Liu Si looked at Qin Tian in confusion, "How can you help me?"

"I know that you were ordered by the big boss to do bad things." Qin Tian said, "I also know that you are very scared now and worried about your safety. But as long as you are willing to cooperate with our investigation and tell us all the information you know about the big boss, we will protect your safety and try to give you a lenient sentence."

Liu Si was silent for a while, then sighed: "Okay, I'll tell you everything I know." He began to tell you all the information and clues he knew about the big boss...

Qin Tian listened to Liu Si's story patiently, nodding from time to time to show his understanding. Liu Si gradually relaxed, and he felt that Qin Tian was not threatening him, but really wanted to help him.

"Boss, he is a very mysterious person," Liu Si began. "I have never seen his real face. Every contact is through the phone or the Internet. His voice is processed and sounds very mechanical. It is impossible to distinguish his real voice."

Qin Tian frowned: "Then how did you carry out his mission? He must have given you some instructions, right?"

Liu Si nodded: "Yes, he will give us a detailed plan and goals. We just need to follow his instructions. After completing the task, he will pay us by transferring money."

"Transfer?" Qin Tian keenly caught this information, "Then do you save the transfer record?"

Liu Si smiled bitterly: "Of course there are, but the records are all in my computer, and now the computer has been taken away by the police."

Qin Tian nodded: "It's okay, we can get these records from the police station. You continue."

Liu Si continued, "The big boss is very cautious. After every contact, he would ask us to destroy the contact equipment immediately and use new contact information. We couldn't track any clues about him at all."

Qin Tian pondered for a moment and asked, "You have been controlled by him for a while, so you should be able to explain something now, right? For example, does he have any special habits? Or has he mentioned anything special?"

Liu Meng pondered for a moment, then shook his head: "Really, I don't know anything. Every time the big boss contacts us, it's very brief, just talking about the task and requirements, nothing else. We don't even know if he is a man or a woman, or how old he is."

Qin Tian frowned even more. This mysterious boss seemed even more unpredictable than they had expected. He sighed and asked another question: "Have you ever thought about why he asked you to steal, blackmail, and even kill people?"

Liu Meng shook his head again: "I haven't thought about it, and I don't dare to ask. We just do things according to his instructions. I guess he might want to gain some benefits or achieve some purpose through these means."

Qin Tian's heart moved, and he asked: "Benefits? Purpose? What do you think it is?" Liu Meng thought about it and replied: "It could be money, it could be power, or it could be something else. We really don't know."

Qin Tian nodded and did not ask any more questions. He knew that he would not be able to get any more valuable information from Liu Meng. So he decided to change the direction of the investigation and start from other aspects.

He stood up and said to Liu Meng, "Liu Meng, I hope you can sincerely cooperate with our investigation. If you still remember any information or clues about the big boss, please tell us at any time. We will ensure your safety and try to give you a lenient sentence."

Liu Meng looked at Qin Tian and nodded seriously: "Okay, I'll tell you everything I know."

After Qin Tian left the ward, he felt something was wrong. Although Liu Meng had confessed a lot, he felt as if he had hidden some key information. Just as he was about to leave the police station and reorganize the clues of the case, a police officer ran over in a hurry.

"Mr. Qin, wait a minute!" the police officer panted, "Liu Meng said he has something important to tell you, about the big boss."

Qin Tian raised his eyebrows, turned around and followed the police officer back to Liu Meng's ward. He saw a complex expression on Liu Meng's face, with hesitation and determination intertwined.

"Liu Meng, have you remembered anything again?" Qin Tian asked calmly.

Liu Meng took a deep breath, and his eyes suddenly became firm: "Mr. Qin, I didn't tell the truth before. In fact, I know the big boss."

Qin Tian was shocked. He keenly caught the key information in Liu Meng's words: "Do you know the big boss? Who is he?"

Liu Meng was silent for a while, as if he was trying to organize his words. Then he said slowly, "Boss, he is actually someone you know. It's just that you may have forgotten him."

Qin Tian frowned, his mind full of doubts and confusion. He tried to recall who he knew might be related to this case. However, after thinking for a long time, he still couldn't come up with a clue.

"Liu Meng, are you kidding me?" Qin Tian's tone was a little stern. "How could there be such a big boss among the people I know?"

Liu Meng shook his head, his expression became a little excited: “I’m not kidding! Mr. Qin, you really know him. It’s just that you may not know his other side. He is your…”

At this point, Liu Meng suddenly stopped, as if hesitating whether to continue. Qin Tian was nervous and expectant, and he couldn't wait to know who this big boss was.

"What is he to me?" Qin Tian urged, "Liu Meng, tell me quickly!"

Liu Meng took a deep breath and mustered up the courage to say: "He is your old friend and your college classmate!"

Qin Tian was stunned as if he had been electrocuted. His mind quickly flashed through bits and pieces of his college life, trying to find memories that matched this big boss. However, no matter how hard he tried to recall, he could not connect the mysterious big boss with any of his college classmates.

"Liu Meng, are you sure you didn't make a mistake?" Qin Tian's voice trembled a little. "Think about it again, did you remember it wrong?"

Liu Meng shook his head firmly: "Mr. Qin, I am not mistaken. Although I have not seen the real face of the big boss, I will never misunderstand his voice. That is the voice of your college classmate."

Qin Tian felt dizzy. He couldn't imagine that his college classmate was the mastermind behind this case. He tried to stay calm and said to Liu Meng, "Okay, I believe you. But I need more evidence to prove your statement. Can you provide any clues?"

Liu Meng thought for a moment, then said, "The big boss once mentioned a place inadvertently on the phone, saying that it was a place he and you often went to when you were in college. It was a bar called 'Old Tree Bar'."

Qin Tian's heart trembled. He remembered that there was indeed a place called "Old Tree Bar" when he was in college. It was a place where his classmates often gathered. Could it be that this big boss was really his college classmate?
Qin Tian stood in front of the shop that had been transformed, feeling mixed emotions. The former "Old Tree Bar" no longer existed, replaced by a new shop. He took a deep breath, mustered up the courage and walked in.

The light in the store was a little dim, but it gave people a peaceful and warm feeling. Qin Tian looked around and found that the store was well organized and all kinds of items were neatly placed. He noticed that the owner was a blind man who was sitting behind the counter, groping with his hands to sort out the account books.

Qin Tian walked to the counter and asked softly: "Hello, I came here to inquire about something. Are you the owner of this store?"

The blind shopkeeper looked up, smiled and said, "Yes, I am the shopkeeper. Is there anything I can help you with?"

Qin Tian hesitated for a moment, but decided to ask directly: "This used to be a shop called 'Old Tree Bar', did you know that?"

The blind shop owner nodded, a look of reminiscence on his face: "Yes, this was indeed a bar before. I heard others mention it before I took over this shop."

Qin Tian was in high spirits and asked hurriedly: "Do you know why the bar closed? Also, have you heard of a big boss related to this bar?"

The blind shop owner pondered for a while and said slowly: "I don't know why the bar closed. I just heard that business was bad and it couldn't continue. As for the big boss, I did hear some rumors."

Qin Tian's heart tightened, and he asked hurriedly: "What rumor? Can you tell me?"

The blind shop owner sighed and said slowly: "I heard that the big boss was a regular customer here and used to come to this bar often. But then, for some reason, he suddenly disappeared. I don't know what happened exactly."

Qin Tian felt a little disappointed, but he still asked unwillingly: "Do you remember anything special about that big boss? Or do you have any clues for me?"

The blind shop owner frowned, as if trying to recall. After a moment, he said, "Although I have never seen the big boss, I heard that he always wears a pair of sunglasses and a black suit, which makes him look very mysterious. I really don't know any other clues."

Qin Tian's heart moved. Sunglasses and black suits were quite similar to the image of the big boss Liu Meng had described. He was excited and felt that he was one step closer to the truth. (End of this chapter)
