"He was coerced? Who coerced him? And what was he being coerced about?" Liang Zichen asked three questions in a row as soon as Wang Shen finished speaking.

Wang Shen glanced at Liang Zichen, but before he could speak, Liang Zichen continued, "That's not right. Han Lin is already dead. What could he possibly have to be coerced about?"

Wang Shen looked at Liang Zichen and sighed softly. "This is easy to explain. Since everyone is human, they must have weaknesses. Han Lin is no exception."

"Weakness?" Liang Zichen raised his eyebrows slightly upon hearing those two words. "Captain Wang, do you already know what Han Lin's weakness is?"

"Think about it carefully, and you'll be able to guess it." Wang Shen didn't give the answer directly, but left Liang Zichen in suspense.

Upon hearing Wang Shen's words, Liang Zichen closed his eyes slightly in thought. After a while, Liang Zichen suddenly opened his eyes wide and stared at Wang Shen: "Could it be his mysterious son?"

Wang Shen nodded slightly at Liang Zichen. "That's what I was guessing too, but I can't be sure yet. I still lack some concrete evidence."

“But, Captain Wang, there’s another problem. Let’s reason this way: Han Lin was coerced, so he had no choice but to die. And the reason the person who coerced Han Lin wanted him dead was definitely to prevent him from revealing certain facts. And these facts happen to be the evidence we need, and they’re also helpful in finding relevant clues to the case. So, since Han Lin accepted the coercion and died as that person wished, why did Han Lin leave these things behind?” At this point, Liang Zichen stared at Han Lin’s phone and the piece of paper Han Lin left behind for a while.

"Shouldn't Han Lin have destroyed all the evidence as demanded by the people who were coercing him?" Liang Zichen asked after thinking for a while.

In fact, Wang Shen had been pondering the questions Liang Zichen had raised since the beginning. After listening to Liang Zichen's words, Wang Shen thought for a while and then said, "Perhaps it's because of resentment? Once a person is resentful, they are capable of anything. Moreover, Han Lin may be thinking that since he is already dead, those who coerced him may also stop. As for the evidence Han Lin left us, we will naturally keep it a secret. These things may be Han Lin's last resentment."

After listening to Wang Shen's explanation, Liang Zichen nodded silently. "By the way, can we trace the origin of that landline?"

"Of course, I've already sent this number to the relevant personnel in the bureau, and I believe we'll get an answer soon." Just as Wang Sheng finished speaking, his phone rang.

"Hello. What? You've already found the location? Okay, send the address to my phone." Wang Shen hung up the phone and exchanged a glance with Liang Zichen.

Within seconds, Wang Shen received a text message containing the landline's address. He opened the message and glanced at the address.

"This address seems familiar..." Wang Shen muttered to himself when he saw the address. After a while, Wang Shen's eyes suddenly widened, his gaze fixed on the address on his phone.

"Have someone conduct a thorough search and collect evidence from the deceased's house. Seal all of this and bring it back to the station for record-keeping," Wang Shen anxiously instructed the police officer standing to the side, then pointed to the cell phone and the piece of paper on the bookshelf. Wang Shen then rushed out of Han Lin's house. Liang Zichen had never seen Wang Shen show such surprise before; after thinking for a moment, he followed Wang Shen out.

As soon as Wang Shen started his car, Liang Zichen jumped in. Wang Shen stepped on the gas, and the car sped towards the entrance of the residential area.

"Captain Wang, where are we going?" Liang Zichen asked Wang Shen, full of doubt. But Wang Shen's eyes were fixed on the road ahead, his brows furrowed, and he completely ignored Liang Zichen's question. Seeing Wang Shen's state, Liang Zichen stopped asking and quietly sat in the passenger seat.

The car had been traveling for quite some time. Wang Shen suddenly slowed down, and the car entered an old residential area. Wang Shen knew the area very well and pulled the car over to the side of the road. He immediately opened the car door and jumped out. Liang Zichen followed behind him.

Liang Zichen finally couldn't hold back any longer and asked again, "Captain Wang, where exactly are we?"

This time, Wang Shen finally responded to Liang Zichen's question. Wang Shen stopped walking, turned around and glanced at Liang Zichen, saying, "Han Mo's house." After saying that, Wang Shen quickly ran into the apartment building.

Han Mo's house? Liang Zichen didn't immediately understand when he heard this. He stopped and didn't chase after Wang Shen for the moment. After standing there for a while, he suddenly realized and exclaimed to himself, "Oh my god! Han Mo's house!"

But why did Wang Shen suddenly come here? Right, Wang Shen rushed here after seeing that text message. The message should have been about the address of the landline on Han Lin's phone. So, could it be...? Yes, that address is Han Mo's home. Then that landline is Han Mo's home phone number? Thinking this, Liang Zichen tapped his head to make sure he was still conscious.

Liang Zichen had reviewed Han Mo's case file, which showed that Han Mo lived alone, meaning that no one would be home after her death. Who made that phone call? A ghost? Thinking this, Liang Zichen suddenly shook his head to clear his mind.

Liang Zichen thought that instead of making wild guesses here, he might as well go with Wang Shen to see for himself. With that thought, Liang Zichen immediately started running and rushed into the apartment building. Liang Zichen ran up a few floors along the stairwell and then spotted Wang Shen. But at this moment, Wang Shen was squatting in a corner of the stairwell, hunched over, his eyes fixed on Han Mo's door.

"Captain Wang, what's wrong?" Liang Zichen ran to Wang Shen's side, but before he could finish speaking, Wang Shen pulled him down to squat in the corner of the stairwell. Wang Shen made a shushing gesture, indicating that Liang Zichen should not speak.

Liang Zichen crouched down behind Wang Shen and glanced at Han Mo's front door, but couldn't see anything unusual. Unable to resist, Liang Zichen lowered his voice and whispered in Wang Shen's ear, "Captain Wang, what's wrong? Did you forget your keys?"

After hearing Liang Zichen's words, Wang Shen glared at him. Seeing Wang Shen's look, Liang Zichen immediately shut his mouth. Although Wang Shen didn't speak, he pointed to the ground in front of him. Liang Zichen looked in the direction Wang Shen was pointing, initially noticing nothing unusual. However, after careful observation, Liang Zichen finally discovered why Wang Shen was crouching at the corner of the stairwell.
