Siheyuan came through and sent Jia Zhang to prison

Ma Xin felt something was amiss, a sense of inexplicable strangeness. But she also understood that she was merely an outsider, an expert helping out, and that knowing too much of the bureau's secrets might not be a good thing. So, she suppressed her doubts, saying nothing more, and calmly followed He Feng.

He Feng led everyone to his office. With a kind smile on his face, he said (in a friendly yet authoritative tone): "I believe Director Bai has already explained this matter in detail to you. I wonder how you plan to conduct your investigation into this matter?"

At that moment, a young man wearing glasses and exuding an artistic air stood up. He stood tall and straight, a confident smile on his face. He politely said (in a clear and firm voice), "Director He, we have a preliminary plan." He then proceeded to explain it to He Feng methodically. His words were concise and logical, each step carefully considered. He Feng listened, nodding slightly with approval. He thought to himself that if this plan was implemented, it would be a sure thing to uncover the hidden spy within.

After listening to this, He Feng's eyes fell on the artistic young man wearing glasses and asked with a smile (his eyes were full of admiration): "I wonder what your name is, comrade?"

The young man smiled, revealing his white teeth, and replied modestly (with a hint of shyness): "My name is Zhang Shi."

He Feng nodded and said seriously (with a serious expression and tone): "This is our first meeting, and we're not very familiar with each other yet. Zhang Shi, they will contact you from now on. Remember, in the Public Security Bureau, don't trust anyone except me. All progress of the investigation should be reported to me alone."

Zhang Shi hadn't expected Director He to place him in such high esteem, having only just arrived. Even before arriving, Director Bai had repeatedly urged him to fully cooperate with Director He and follow his instructions. At that moment, he felt both honored and deeply aware of the immense responsibility.

Just as He Feng was about to explain some details, there was a sudden knock on the office door. The "knock knock knock" sound was particularly clear in the quiet office.

He Feng raised his voice slightly and said, "Please come in." The door slowly opened and Director Zheng walked in. Seeing this, He Feng smiled and said (in a relaxed tone): "Director Zheng, you've come at the right time. These are the comrades who are here to study. I'll trouble you to make the arrangements next."

Zheng Qiang glanced at the group of energetic young people before him, a trace of doubt in his heart. What kind of business were they here to learn? However, he nodded without hesitation and said to the director in a firm tone, "Director, rest assured. I will make the proper arrangements right away." With that, he led the group of young people away in an orderly manner, their steps hurried, as if carrying a sense of mission.

He Feng stood at the door, watching them go away. He was about to turn around and go back to his office to continue working. At this moment, Ma Xin walked over with a brisk pace, a curious look on his face, and asked, "Director, what on earth are these young people doing here?"

A faint smile crossed He Feng's face. This matter involved some confidential work arrangements, which could not be disclosed at the moment. He patiently explained, "They were sent by Director Bai next door to study with us. This is also a unified arrangement from our superiors. Later, our bureau will select a few people to go over for exchange and learning."

Ma Xin's eyes lit up after hearing this, and a strong desire for knowledge surged in her heart. She looked at He Feng and said, "Director, I really want to go and take a look too. I heard that their crime-solving rate there is among the best in the entire region. There must be a lot we can learn from them."

He Feng shook his head slightly and refused directly: "You can't do that."

When Ma Xin heard this answer, her heart suddenly tightened, and the smile on her face froze instantly. She looked straight at He Feng, her eyes full of confusion and loss, and couldn't help but wonder if He Feng didn't want her to go because he disliked her lack of ability.

As soon as He Feng said this, he realized he had been too direct and had probably caused Ma Xin to misunderstand him. He quickly explained with a smile, "Ma Xin, please don't misunderstand me. That's not what I meant. You know, we don't have many experts in the Public Security Bureau. If someone as experienced and capable as you were to go out and study, and if there were a major case during this period, we'd be very short on manpower."

After hearing He Feng's explanation, Ma Xin's doubts immediately dissipated. She couldn't help but laugh, thinking that He Feng, the usually serious director, had such an interesting side. She said, "Director, I understand what you're talking about. I'll get back to work."

He Feng smiled and nodded, watching Ma Xin leave, then turned and returned to his office. As soon as he sat down, he picked up the phone and dialed Bai Yu's number. The call was quickly connected, and He Feng said enthusiastically, "Brother Bai, thank you so much for your help this time! If you hadn't reached out in time, I really don't know how I would have handled this matter."

Bai Yu's hearty laughter came from the other end of the phone: "Alright, we're all brothers, why be so polite. Just treat me to a drink when you have time!"

Just as He Feng was about to hang up the phone, Bai Yu seemed to suddenly remember something and said with a smile, "Actually, I have something to ask of you."

He Feng responded without hesitation: "Brother Bai, if you have anything to say, just say it directly. Why are you being so polite to me?"

Bai Yu cleared his throat and slowly explained the situation. "It's actually a child theft case. This is my first time dealing with this type of case, and it's quite tricky. I know you've solved a similar major case before, so I'd like to learn from you. You must have a lot of experience."

He Feng listened carefully, and after Bai Yu finished speaking, he told him his experience in solving the case at that time: "This is what I did at the time... If you follow this idea when the time comes, there shouldn't be any big problems. However, time is of the essence for cases like this, so you must act as soon as possible." As he spoke, he recalled the details of that year in his mind, wishing to convey every key point clearly to Bai Yu.
