Looking back, Ning Xin'er had really been quite diligent when it came to studying. During her time at the police academy, not wanting others to laugh at her for being a mere "flower vase," she had worked hard learning various combat techniques and investigation theories. Her efforts finally paid off, and in less than six months she became one of the academy's top students, excelling in every subject. However, upon becoming a police officer, her lack of experience meant that she didn't stand out—until Su Zhenggang arrived. He found that despite her experience and courage being lacking, her heart was in the right place and she had a meticulous mind. Having just arrived in Baiyun City, Su Zhenggang naturally wanted to nurture a group of loyal subordinates for himself. He wasn't quite sure about the previous officers—worried that they might have been corrupted. With new recruits like Ning Xin'er, he started building his own team, and she was one of those he had his eye on.
