Upon hearing this, Zhu Qinghao turned around and gave him a look that was hard to describe (disdain).

The elder saw all of this and almost burst out laughing.

"Boss! I think this matter is quite serious!"

Lu Zheng seemed displeased with his smile, so he emphasized it.

However, these words only made the elder smile even wider.

"Alright, kid, I think you've become obsessed with solving cases all day long, you see everyone as a suspect."

Although his words contained some reproach, there was not a trace of displeasure on his face. Instead, he smiled and said to Zhu Qinghao:

“My apprentice is just that kind of person. He’s not deliberately targeting you. I hope you won’t take it to heart.”

Zhu Qinghao quickly shook her head, indicating that she wouldn't take it to heart.

Lu Zheng, however, was not so easy to talk to. He strode up to Zhu Xinhao, looked at her, and said coldly:

"This comrade..."

Zhu Qinghao naturally didn't give a friendly look to someone who doubted her from the start, especially since she had helped him. She coldly interrupted him.

"My name is Zhu Qinghao."

Upon hearing this, the elder laughed again.

After being interrupted, Lu Zheng took a deep breath and continued to ask:

"Comrade Zhu Qing, I'd like to ask, how did you figure out and confirm that those two people were human traffickers?"

“I wasn’t sure. When I found you, I told you I had my suspicions. I never knew for sure that they were human traffickers.”

Zhu Qinghao's humble yet assertive attitude actually made Lu Zheng somewhat believe that she had nothing to do with those two human traffickers, but for some reason he felt even more annoyed.

"Okay, then I'd like to ask, what makes you suspect that they are human traffickers?"

"Because they said it was their child, but it doesn't look like it to me."

That couple—or maybe they weren't even a couple, it could be a fake—they looked like they were old enough to have grandchildren running around, not like they could have had such a young child.

The elder listened and nodded, offering no comment.

"Also, the old lady appeared next to me first, and the old man came several hours later. It's unlikely that such a young child could be separated from his mother for so long."

Furthermore, the child was unusually quiet; after being brought to my side, he lay motionless in my arms. All these behaviors combined made it hard not to suspect something was wrong.

Zhu Qinghao didn't wait for Lu Zheng to ask any more questions before continuing to talk. The main reason was that the person's words were really unpleasant, and she was too lazy to listen to them, and really didn't like listening to them.

Unexpectedly, after I finished speaking, Lu Zheng asked even more unpleasant questions.

Why are you so interested in a couple you don't know? Can you honestly say you have no connection to them?

Because of her good manners, Zhu Qinghao didn't roll her eyes, but the expression on her face was not much different from rolling her eyes.

"Brother, I understand your desire to solve the case, and I also agree with your dedication to the job, which is to rather kill a thousand innocent people than let one guilty person go free."

However, your suspicions are a bit too far-fetched.

If I knew them, or were in their group, what would be the point of me coming to the dining car to find you? Do you think I'm upholding justice by turning against my own people, or engaging in fratricide?

Lu Zheng seemed stumped by the question. He glanced at his superior, his lips twitching a few times but he couldn't utter a word.
