"A reasonable explanation? What reasonable explanation is there for the things of this world and the human heart?" Xu Xiaolin gave a bitter smile, slightly raising her head, her face still adorned with exquisite makeup and radiating confidence. "I think it might be because of hatred."

"hatred?"

"We all know that Han Mo was raped by Zheng Wu, and her mother actually endured it. Who wouldn't lose their most basic faith in the world after that? For this reason, I think Han Mo wants revenge. Now that she has something on Zheng Wu, she can threaten and attack him at will when she is powerful enough." When Xu Xiaolin said these words, it was as if she was stating a most basic fact in a novel, and even her tone was unusually calm.

"Can revenge make a person so terrifying? To abandon even the deepest love and family ties?" Wang Shen frowned after hearing Xu Xiaolin's words.

"Most people cherish the deep love and kinship because most people find happiness and support in this kind of relationship. But what did Han Mo gain? If we try to constrain her with universal social norms, then she is truly pitiful."

"So how did you get this video? And who are you?" Wang Shen stared at Xu Xiaolin, waiting for her to answer this question that he couldn't understand.

Xu Xiaolin just smiled and turned to leave the room.

"Wait!" Wang Shen called out to Xu Xiaolin.

"Officer Wang, I'm not your prisoner. And I also have the right to remain silent."

"Xiaolin, we've known each other since we were little, but we lost touch after we went to university. I think you've changed a lot since we reunited this time."

"People always change, that's an undeniable fact. Maybe it's not me who's changed, but you. You've become... even more handsome." Xu Xiaolin turned back and smiled at Wang Shen again before leaving the room.

Wang Shen stood there, watching Xu Xiaolin's departing figure, lost in thought. As if remembering something, Wang Shen quickly left the house as well.

Through Wang Shen's extensive communication and coordination, he finally found complete files on Han Mo and Xu Xiaolin from birth. The information in the files confirmed Wang Shen's earlier suspicions. It turned out that nothing was a coincidence. How could two people who look so alike exist in this world without any reason?

The files show that Han Mo is her changed name; Han Mo was previously called Xu Xiaomo. Xu Xiaolin and Xu Xiaomo are clearly biological sisters. If this is true, according to the scattered diary entries, Han Mo and Xu Xiaolin should have re-established contact and maintained contact several years ago. Xu Xiaolin knew about Han Mo's life, so she must have harbored immense anger over Han Mo's death. Following this line of reasoning, everything Xu Xiaolin did was for revenge. Therefore, the novel Han Mo initially wrote was merely to draw public attention to the Han Mo incident, prompting the police to reopen the investigation. Zheng Wu was likely a carefully orchestrated scheme by Xu Xiaolin. Now, after years of torment, Zheng Wu's crimes have been exposed, a severe punishment for his past offenses. However, one thing remains a question for Wang Shen: Did Xu Xiaolin know who Han Mo's killer was? Based on the current situation, Xu Xiaolin probably didn't know. Otherwise, she wouldn't have gone to such lengths to investigate the case. Handing the evidence over to the police would have been more direct. Or...? Wang Shen recalled how Zheng Wu had gradually fallen into Xu Xiaolin's trap, and a chill ran down his spine. Xu Xiaolin had truly changed a lot compared to a few years ago. Wang Shen sighed inwardly.

Over the past few days, Wang Shen had called Xu Xiaolin several times. Strangely, each time he dialed, her phone was either switched off or busy; he couldn't reach her at all. But this morning, as soon as Wang Shen arrived at the office, he saw everyone holding their phones and discussing the matter.

"What's going on today? Why aren't you working this early in the morning?" Wang Shen asked, half-jokingly, noticing the noisy atmosphere in the office.

"Captain, big news!" A policewoman stood up from her chair and waved her phone at Wang Shen.

"ah?"

"Captain, your news is really late. It's that helper you brought, that novelist. So she's Han Mo's younger sister! I was wondering what a coincidence it was, two people who look so alike." The policewoman chatted about the news with great interest, secretly admiring her own initial guess.
