Possibly sensing someone staring at her, Sun Ying turned her head to look at Xu Mo.
The two gazed at each other.
Finally, Xu Mo walked over with a puzzled expression and asked:
"These are all your brother's clothes, right? He just left not long ago, and you're already throwing all his clothes away?"
Sun Ying replied emotionlessly:
"He's not coming back anyway, is he? What's the point of keeping these things?"
Hearing this, Xu Mo narrowed his eyes and scrutinized Sun Ying.
It seemed she truly knew about Sun Jian's murder, and that Xu Mo was a police officer who had come to arrest Sun Jian.
She also knew that Sun Jian's crimes were severe enough to warrant life imprisonment or even the death penalty.
That's why she chose this time to discard all of Sun Jian's clothing.
"You know he's not coming back? So... you knew your brother killed someone all along?"
Xu Mo wondered if Sun Jian's sister, Sun Ying, was guilty of failing to report a crime or harboring a criminal.
Or perhaps something even more serious, like... instigating murder?
It was possible that Sun Jian had killed someone under Sun Ying's instruction.
No... that's not right, Xu Mo immediately dismissed the thought.
Because he suddenly recalled Sun Jian's last words in the interrogation room.
Xu Mo, well-versed in psychology, could tell at a glance that Sun Jian wasn't lying then. In Sun Jian's view, Sun Ying knew nothing about his murder!
Yet paradoxically, Sun Ying did know about it, and it seemed she had known for quite some time.
A chill ran down Xu Mo's spine.
He was reminded of a movie from a parallel universe - Detective Chinatown 1.
The film ended with a little girl's eerie smile.
The person arrested wasn't the true culprit; the little girl at the end was the real mastermind behind the scenes!
The one arrested was just a scapegoat, or rather, merely a tool being used.
The little girl had used her diary to manipulate her foster father into killing for her.
She had a motive for the crime, but there was no evidence to support her instigation of murder. Legally, her actions couldn't be defined as criminal.
It was nearly the perfect crime - using someone else as a weapon while remaining free from legal consequences...
Faced with Xu Mo's inquiry, Sun Ying just smiled strangely. Her smile was almost identical to that of the little girl at the end of Detective Chinatown 1 in the parallel universe.
"I didn't know all along, I just found out he killed someone," the girl explained.
"Just found out? How did you know? This information is still confidential; only the police know who the killer is right now."
"I guessed, of course. How could I not know when someone died at my internship place? I know my brother's personality very well, and he happened to be away from home when the crime occurred. Plus, the police showed up soon after he came home. Isn't it easy to connect the dots and figure out he killed someone?"
This smile, this tone, in Xu Mo's view, was blatant provocation.
Just guessed? As if!
Given your reaction, there's no way you just found out!
Your brother got arrested because of you, and you're not even sad? You can still smile?
At this moment, Xu Mo believed that Sun Jian's murder must have been influenced by his sister.
In other words, Sun Jian was merely a tool being used, completely unaware of everything.
The real murderer should be Sun Ying!
And the reason Sun Ying dared to provoke Xu Mo so boldly
was because she was confident that Xu Mo couldn't do anything to her, confident that she could escape justice!
She had a motive for the crime, but legally her actions couldn't be defined as criminal. After all, there was no evidence to prove she had committed a crime.
The little girl in Detective Chinatown 1 had escaped justice in the same way.
However, Sun Ying was unlucky to have encountered Xu Mo.
The reason the little girl in the movie could escape justice was that the police couldn't gather evidence.
Even if they suspected the little girl was involved, they could do nothing about it.
This method of using someone else as a weapon was too sophisticated, using the 'weapon' without their knowledge.
But while the police in the movie had no options, that didn't mean Xu Mo was helpless.
He had truth serum!
One injection, and Sun Ying would reveal everything.
At that point, both the motive for murder and the evidence would be available.
Perfect crime? No such thing!
Of course, Xu Mo didn't know what the truth really was.
Although based on Sun Ying's behavior, there was a high probability that things were as Xu Mo imagined, this was still just his speculation.
The specifics would need to be tested to know for sure.
"That makes sense, it's normal for you to have guessed this," Xu Mo didn't reveal his suspicions, instead concealing them well: "Your brother wants to see you. Come with me, I'll take you to the police station."
"Okay."
They walked together to the parking lot and got into Xu Mo's car.
Before getting in, Xu Mo, under the pretense of helping open the car door, quickly approached Sun Ying and injected the truth serum into the back of her neck, then immediately stuffed the serum into his system space.
The truth serum vanished from Xu Mo's hand as it entered the system space.
Sun Ying felt something prick the back of her neck and immediately turned to look, only to see Xu Mo slapping his own arm and muttering to himself.
"Damn mosquito! They come out as soon as it gets warm, their bites sting like needles!"
Sun Ying also rubbed the back of her neck.
She didn't notice anything unusual.
She knew that the large flower mosquitoes in the residential green areas had painful bites. Some mosquito bites indeed felt like needle pricks.
Due to Xu Mo's misdirection,
she mistook the sharp pain of the truth serum injection in her neck for a mosquito bite.
The truth serum took effect immediately after the injection.
Once Sun Ying was in the car, Xu Mo began to question her.
"Was Sun Jian's murder related to you?"
"Yes," Sun Ying nodded. "His killing of Zhang Guodong was the result of my intentional and unintentional manipulation. I understand his personality."
Although Xu Mo had previously suspected this outcome,
hearing it confirmed firsthand still sent chills down his spine. He instinctively glanced at Sun Ying sitting in the back seat through the rearview mirror.
Instigating her own brother to commit murder... this had ruined two lives at once!
And one of them was her own family member.
Xu Mo could understand why Sun Ying wanted to kill Zhang Guodong.
After all, this Zhang Guodong was indeed not a good person.
But what Xu Mo couldn't understand was why Sun Ying, knowing that murder was illegal, would still manipulate her brother to take such a risk?
Especially when, upon learning that Sun Jian had been arrested and wouldn't be coming back, Sun Ying, as his sister, showed no signs of sadness at all?
"Do you have conflicts with your brother? Do you hate him?"
"My brother? I have no blood relation to him at all. He's not my brother. He's just like Zhang Guodong, neither of them are good people!"
Xu Mo furrowed his brow.
