Siheyuan came through and sent Jia Zhang to prison

He Feng nodded solemnly and said, "Alright, you guys clean up here carefully. Remember, don't miss even the slightest clue. You must go all out and try to find any useful clues."

He Feng knew that his current state was a bit confusing. Instead of worrying about it, it would be better to let these professional police officers investigate here. They might be able to find key information from this chaos and solve this series of mysteries.

Ma Xin looked at He Feng and asked worriedly, "He Feng, what do you think we should do now? This case seems to be getting more and more complicated..."

He Feng fell into deep thought. He knew this was just a setback in the investigation and he must not back down. He took a deep breath, trying to calm himself down, reorganize his thoughts, and find the next step.

He Feng looked lonely, his eyes revealing a deep sense of frustration. He looked at Ma Xin and said in a low voice: "I don't know what to do. I feel like I can't do anything right. Am I just a waste?" At this moment, he seemed to be shrouded in a layer of haze, full of disappointment in himself.

Ma Xin hurried forward, his eyes full of concern and comfort, and said: "Director, how can you say that! How can you be blamed for this? This is all the work of those evil people. They are the culprits. You have tried your best." Ma Xin tried to use words to dispel the haze in He Feng's heart and cheer him up again.

He Feng listened to Ma Xin's words and nodded slightly, but didn't say anything more. He turned around and walked back silently. He originally had a lot to say to Ma Xin, but when the words came to his lips, he didn't know where to start, so he chose to remain silent.

Ma Xin looked at He Feng's back, feeling as if he had something difficult to say. After hesitating for a moment, she quickly caught up with him, looked at He Feng, and asked softly, "He Feng, do you have something to ask me? It seems like you have something on your mind."

He Feng stopped, turned his head, looked straight at Ma Xin, and asked slowly: "The last time, who was it you or Ma Ran who investigated the bodies of those heroes with me?" This question had been lingering in his mind for a long time, and he finally couldn't help but ask it at this moment.

Ma Xin's heart tightened when she heard this question, and a subtle flash of panic flashed across her eyes. But she quickly calmed down and looked at He Feng, pretending to be calm and saying, "The person I investigated with you last time was indeed Ma Ran. She's much better than me in this area and has a lot of experience. I, on the other hand, have only just started working in this field and am still a novice."

After listening to Ma Xin's explanation, He Feng suddenly understood. Recalling the previous investigation, the man had even mistaken the weapon, which certainly didn't seem like the work of an expert. But he had already promised Ma Ran that he would take care of her, so he couldn't say anything more. He nodded and said, "I see. In that case, you should study hard with Director Li and gain more experience."

Seeing that He Feng didn't seem to have too many doubts about him, Ma Xin secretly breathed a sigh of relief. He nodded quickly and said, "He Feng, Ma Ran and I actually have similar knowledge, but I've always lacked many opportunities to practice. Ma Ran always prevents me from participating in these investigations, saying that he's worried that something might happen to me."

He Feng listened to Ma Xin's words without commenting. He turned silently and walked towards the Public Security Bureau. After walking for a while, he suddenly stopped, turned to look at Ma Xin, and said, "Ma Xin, I remember you haven't practiced shooting for a while. Since there's nothing urgent at the bureau today, why don't we go over there and practice shooting together? It can also improve our professional skills."

Ma Xin looked at He Feng helplessly, her eyes full of confusion and resistance, and said, "He Feng, I'm just a forensic doctor. My daily job is to deal with corpses and study the cause of death. There's really no need for something like shooting." She really couldn't understand why she had to learn to shoot. It seemed to have nothing to do with her job.

He Feng frowned slightly, his mind racing back to his last time with Ma Ran. Ma Ran, who had displayed exceptional firearm prowess at times, yet still feigned incompetence, was acting suspiciously. He Feng felt that in this complex and dangerous situation, everyone around him should possess a certain level of self-protection. So, he decided to patiently explain the reasoning to Ma Xin.

He Feng repeated to Ma Xin exactly what he had said to Ma Ran at that time, and said in a serious tone: "The current situation is still very dangerous. We don't know when we will face an emergency. As a member of the team, it is crucial for you to learn to protect yourself. One more skill means one more security." He Feng's eyes revealed worry and concern, and he sincerely hoped that Ma Xin would take it seriously.

After hearing what He Feng said, Ma Xin moved her lips, as if she wanted to refute something, but she finally swallowed her words. She looked at He Feng's serious expression and knew that arguing any further would be useless, so she had no choice but to accept this fact.

Afterwards, He Feng brought Ma Xin to the Public Security Bureau's training center. Gunfire rang out from the training grounds as the officers engaged in their daily training. He Feng knew the Public Security Bureau's current strict requirements for officers required regular assessments to ensure they maintained their combat skills and emergency response capabilities.

He Feng walked to the registration desk at the training ground, signed in expertly, and then asked the staff for two pistols. He turned and walked over to Ma Xin, saying, "Ma Xin, let me explain in detail how to use a gun. You must listen carefully, as this concerns your safety."

Ma Xin nodded, a hint of nervousness and curiosity in her eyes. It was her first time handling a pistol so closely, and she felt a mixture of fear and anticipation.

He Feng patiently began explaining everything from the pistol's basic structure and the functions of its various components to how to properly hold, aim, and pull the trigger. After a while, He Feng paused, looked at Ma Xin, and said, "No matter how much theoretical knowledge you talk about, it's not as good as practical experience. So why not try this pistol? Everything should be based on practical experience. Only by practicing it yourself can you truly master the skills of shooting."

Ma Xin took a deep breath and slowly picked up the pistol. Her hands were trembling slightly as she looked at He Feng and said, "This is my first time firing a gun, and I'm a little scared." Ma Xin's expression was slightly nervous, and beads of sweat even appeared on her forehead.
