After Wang Shen finished speaking, Liang Zichen responded, "Xiao Lin's explanation for entering Han Mo's room might be true. But the key was very likely already in his possession. Captain Wang, is that what you mean?"

Wang Shen completely agreed with Liang Zichen's point of view, saying, "That's right. The child I saw in the surveillance footage was probably arranged by Xiao Lin in advance. And the package thrown into Xiao Lin's window, I don't think it could be Han Mo's house key."

"If our assumptions are entirely correct, then the more important question now is, how did Xiao Lin obtain that key? And what leverage does Han Lin have over him that ultimately leads to Han Lin's death?" Liang Zichen connected Tang Feng's murder case with Han Lin's case, and even Han Mo's case.

“Xiao Lin has a key to Han Mo’s house, and that key must have come from Han Mo. Also, let’s not forget Xiao Lin’s former identity; he was Han Mo’s assistant. So what exactly is it about Xiao Lin that Han Lin has in his hands…” At this point, Wang Shen paused, still clenching his right fist and tapping his chin repeatedly.

Having followed Wang Shen for so long, Liang Zichen understood that when Wang Shen made this habitual gesture, it meant he was pondering something important. Liang Zichen quietly awaited Wang Shen's answer.

After a while, Wang Shen lowered his fist, glanced at Liang Zichen, and said, "We can make a bold guess: Xiao Lin's incriminating evidence is closely related to Han Mo's murder case."

Sure enough, the root of all the problems still stemmed from Han Mo's case.

"What kind of connection could there be?" Liang Zichen's expression turned serious upon hearing Wang Shen's conjecture. Liang Zichen had also pondered this question, but had never been able to find a clear answer.

Wang Shen flipped through a few pages of his notebook, and when he reached a blank space, he began to write.

As Wang Shen wrote, he answered Liang Zichen's questions: "We know that Han Lin delivered food to Han Mo on the night of Han Mo's incident. According to Han Lin, he didn't even go inside. Then Han Lin called Han Mo and heard Han Mo's phone ringing from inside the house. However, based on the clues we have so far, Han Lin's testimony may not be credible."

Liang Zichen roughly understood Wang Shen's meaning, and following up on Wang Shen's words, Liang Zichen began his own speculation. "So, Han Lin entered the house and very likely witnessed Xiao Lin committing the crime?"

Wang Shen's pen didn't stop; he just listened to Liang Zichen's words while nodding.

"If that's the case, why didn't Han Lin call the police back then? Xiao Lin discovered that his actions had been exposed, and given his current style of doing things, he probably wouldn't have let Han Lin off the hook. But why did he only deal with Han Lin now?" Although Wang Shen's speculation was reasonable, the details Liang Zichen mentioned did indeed raise many doubts.

Wang Shen finally put down his pen. He listened carefully to Liang Zichen's question, and then said, "Han Lin chose not to call the police and helped Xiao Lin cover it up for so long. There must be a reason for this. I think the safety of Dean Fu Ju and Han Lin's child is Xiao Lin's biggest leverage in coercing Han Lin."

"That's not right." Liang Zichen, unusually, shook his head in disagreement with Wang Shen's deduction. "Xiao Lin using Dean Fu Ju and the child's safety to coerce Han Lin is perfectly reasonable. But Captain Wang, you've overlooked a crucial point. If, as we suspect, Han Lin witnessed Xiao Lin's attack, his first reaction would be terror, followed by escape, and ultimately, calling the police or remaining silent. However, at that point, Xiao Lin should not have known about Dean Fu Ju and Han Lin's child. Since Xiao Lin didn't know this, how could he possibly use them to coerce Han Lin?"

After listening to Liang Zichen's analysis, Wang Shen frowned slightly, then nodded in agreement.

After seeing Wang Shen's reaction, Liang Zichen continued his analysis: "Therefore, I think the reason Han Lin didn't call the police at first wasn't because he was coerced. It was only later, fearing Han Lin might change his mind at any time, that Xiao Lin used some methods to obtain information about Han Lin and learned about the existence of Dean Fu Ju and the child. In the end, Dean Fu Ju and the child became Xiao Lin's trump card. But, what was the real reason Han Lin didn't call the police at first?"

Although Liang Zichen rejected Wang Shen's initial guess, he still couldn't understand Han Lin's initial motive for not calling the police.

As Liang Zichen explained his point of view, Wang Shen nodded repeatedly. Now, Liang Zichen fell silent. Wang Shen smiled and looked at Liang Zichen, saying, "Your analysis is indeed reasonable, and that's something I hadn't considered. Now let's start analyzing from your question. The reason Han Lin initially didn't choose to call the police was probably because he thought it was better to avoid trouble. Many people have a 'not my problem' mentality, which isn't surprising."

Wang Shen's answer still didn't satisfy Liang Zichen. "But since Xiao Lin has already seen Han Lin, Han Lin is a ticking time bomb for the murderer. Do you think Xiao Lin would let this time bomb stay by his side?"

“That’s right!” Wang Shen clapped his hands. “Xiao Lin wouldn’t let this bomb explode; he must have found Han Lin later. Let’s not forget Xiao Lin’s identity; he’s Han Mo’s assistant. And according to A-Cheng’s description, Xiao Lin sometimes accompanied Han Mo to and from ‘Spicy Restaurant.’ So, Xiao Lin must be able to recognize Han Lin as the manager of ‘Spicy Restaurant.’ Then finding Han Lin won’t be difficult for Xiao Lin.”

Now it was Liang Zichen's turn to nod continuously.

“However, the moment Xiao Lin approaches Han Lin, Xiao Lin will surely understand the drawbacks of this approach,” Wang Shen smiled and then added.

"Drawbacks?" Liang Zichen widened his eyes slightly, his gaze filled with intense curiosity.

Wang Shen nodded, then picked up the water glass on the table and took a sip. "Think about it, if a murderer came knocking on your door, wouldn't you be scared?"

Liang Zichen thought for a while, then shook his head.

Wang Shen sighed and said, "I'm saying, what if an ordinary person were in this situation?"

Liang Zichen thought for a moment, then nodded heavily.

"So, the murderer came knocking on his door, shattering Han Lin's previous mindset of 'it's none of my business.' In this situation, if the murderer can't eliminate Han Lin as well, what do you think Han Lin will do next to protect himself?"

Liang Zichen thought for a moment, then answered with two words: "Call the police!"

“That’s right!” Wang Shen clapped his hands. “But! Han Lin didn’t do that!”
