Siheyuan came through and sent Jia Zhang to prison

At this time, He Feng stood quietly, his eyes following Ma Xin's figure until she gradually walked away and disappeared at the end of the corridor. He frowned slightly, and the doubts in his heart became more and more serious.

Then, he slowly pulled a pair of gloves from his pocket, his movements calm and cautious, as if he were performing a crucial ritual. He gently picked up the pistol that Ma Xin had just used and carefully placed it in his gloves, his expression as if he were treating a precious object containing a great secret.

He Feng had always harbored a faint suspicion about Ma Xin. He felt that many details in this case seemed suspicious, and some of Ma Xin's actions and behaviors left him feeling uneasy. With this suspicion in mind, he turned and headed towards the firearms management room.

Walking into the gun management room, there was a faint smell of oil and metal. Old Zhao, the gun management officer, was sitting at the table, concentrating on sorting out the gun files. Seeing He Feng come in, Old Zhao quickly stood up, with a respectful smile on his face, and said, "Director, you're here."

He Feng nodded slightly, his eyes serious. He handed the glove containing the pistol to Lao Zhao and said, "Lao Zhao, I need to take this gun out." Lao Zhao was stunned for a moment, a hint of doubt flashing in his eyes, but he didn't ask any more questions. He Feng then said, "I don't want anyone to know about this." Lao Zhao instantly understood that the director had something important and confidential to arrange. He nodded vigorously and said firmly, "Director, don't worry. I'm very tight-lipped. I will arrange this matter properly and ensure that no one else will know."

He Feng nodded with satisfaction, removed the gun from his gloves, gently placed it in an evidence box, and closed the lid. He knew that if he investigated some matters within his own bureau, various factors might interfere with the investigation, making it difficult to uncover the truth. Therefore, he decided to go to another public security bureau to utilize their relatively independent resources and perspective.

He Feng took the evidence box and turned to walk out. As he reached the Public Security Bureau entrance, he happened to see Ma Xin and Zhao Lei standing nearby, talking in low voices. Both of them looked grave, as if they were discussing a key issue in the case.

Zhao Lei, with his sharp eyes, stopped talking immediately when he saw He Feng coming out. He quickly walked over, saluted, and said, "Director, we found a box of matches at the scene. These matches are everywhere and are very common on the market. It's too difficult to trace the source now. It's difficult to investigate for the time being." He Feng frowned slightly, thought for a moment, nodded, and said, "Continue the investigation. Don't miss any details. Even if there is little hope, you must get to the bottom of it. I'm going to be out for a while. Please take care of the affairs of the bureau."

Ma Xin watched He Feng from the side, feeling that his actions today were somewhat odd, different from usual. From the moment he drew his pistol to the moment he prepared to leave, his actions were all filled with mystery. Although she felt puzzled, she didn't say much. After all, as the director, He Feng always had his own considerations and plans.

After He Feng got in the car and left, Ma Xin watched the car drive away, her doubts growing stronger. She turned to Zhao Lei and asked, "Zhao Lei, what do you think Director He is busy with? Why does he seem strange today?" Zhao Lei shook his head helplessly and said, "I'm not sure either. The director always has his own reasons for doing things. But Expert Ma, you have a good relationship with Director He. If you have the chance, you must persuade Director He. You know, the murderer has not been found yet. Director He must be feeling very upset and under a lot of pressure."

Ma Xin sighed softly and nodded, his eyes still fixed on the direction where the car disappeared, and said, "Okay, I got it. You have to investigate thoroughly on your side too. We must find the murderer as soon as possible. We can't let Director He worry about this anymore." Zhao Lei nodded vigorously, his eyes firm, and said, "Don't worry, Expert Ma, I will do my best." After that, he turned and hurriedly walked towards the direction of the investigation scene, continuing to devote himself to the intense investigation work.

Ma Xin tilted her head slightly, her eyes somewhat blank, staring blankly to the side, her mind constantly replaying what He Feng had just said to her. Those words circled around in her mind over and over again, but she racked her brains, but she really couldn't guess what He Feng was up to. Her heart was full of doubts, but she couldn't find a clue.

He Feng's expression was solemn, his gun tightly gripped as he hurried to another police station. Faced with this complex case, he knew he needed outside help. He had known the director of this police station, Bai Yu, for a long time. Bai Yu was a well-known figure in the police force, having solved numerous difficult cases with his exceptional wisdom and experience. Whenever He Feng saw him, he affectionately addressed him as "Brother Bai."

As soon as He Feng entered the Public Security Bureau compound, he saw Bai Yu walking out of the office building. Bai Yu was tall and straight, with a capable and wise look in his eyes. He Feng hurried forward, a smile on his face, and said, "Brother Bai, what are you doing?"

Bai Yu was stunned for a moment, then turned around and saw that it was He Feng. He couldn't help laughing and teasingly said, "He Feng, you are really a rare guest. Tell me, what do you want to see me about? You never come to me for no reason." Bai Yu knew He Feng's character very well. He would not come to him easily unless he encountered a difficult problem.

He Feng didn't waste any time. He carefully pulled out the evidence box from his pocket and handed it to Bai Yu. He said seriously, "Brother Bai, please help me check the fingerprints on it. I also have a fingerprint sample from someone else. Please compare them and see if they are the same." He then took out two small evidence bags from his pocket and continued, "These contain hair. Please help me see if there is any relationship between them. This is extremely important to me."

Bai Yu took the evidence, looked at He Feng, and asked with a hint of confusion, "Why, are all those advanced inspection equipment in your bureau on strike? Why did you come to me?"

He Feng smiled helplessly and explained: "Brother Bai, to be honest, we have a small problem and we can't conduct these tests for the time being. This matter is really too important to me. After thinking about it, I only believe that you can help me solve this problem." He Feng's eyes were full of sincerity and expectation.
