"Uh...I'm afraid this will disappoint the professor. The other party's technique is very professional. We have already extracted the fingerprints on the doorknob, but found nothing." Although he didn't want to admit it, Chen Long had to admit that they did not find anything useful. Clues.

The only discovery was the fat factory director in front of him.

"What about him?"

"Lu Zhiqiang, the director of the glass factory, only has the key to the insurance room, and he is also the biggest suspect in this case." Chen Long reported: "However, so far, no useful information has been asked."

"We are preparing to take him back to the game to continue inquiries."

Lu Zhiqiang?

Qin Luo didn't speak in a hurry, but squinted his eyes and looked at Lu Zhiqiang seriously.

"Qin, Professor Qin..." Lu Zhiqiang said tremblingly.

The corners of the mouth twitched slightly, the forehead was sweating, the fingers trembled slightly, and there was a slight tremor in speaking...

This is something that only appears when you are extremely nervous.

After pondering for a while, Qin Luo said: "Let him go, he doesn't know anything."

Qin Guotao:? ? ?

Chen Long:! ! !

Everyone:...

Nima, is this all meant to be?

Let people go if they don't agree?

Forgive them for not reading, at this moment, their minds are a little bit confused.

"Qin, Professor Qin, what do you mean..." Chen Long asked with a trembling voice.

"I said he is not a thief." Qin Luo shrugged and said with a smile: "It is impossible for him to know anything."

It's okay for Qin Luo not to speak, the more he talks, the more confused people become.

Why did Qin Luo know that Lu Zhiqiang was not a thief and knew nothing?

"Professor Qin, there is always a reason, right?" Chen Long gritted his teeth and asked.

He really didn't understand Qin Luo's unprovoked words.

Qin Luo held up **** and said, "Two reasons."

"First, as the director of the glass factory, Lu Zhiqiang did not have any motivation to commit the crime as to why he would steal samples."

"What if he wants the process?" Chen Long asked.

"Team Chen, you must remember that Lu Zhiqiang is the factory director. Let’s not talk about whether the manufacturing process is kept secret from him. Even if it is kept secret, he can obtain the process flow by side-by-side attack. There is no need to risk such a big deal. Risk." Qin Luo said.

Hearing Qin Luo's words, Chen Long thought about it seriously. It is undeniable that he felt that Qin Luo's words did have some truth.

"What about the second point?"

"The second point is simpler. He doesn't have the conditions for committing crimes at all." Qin Luo said: "If he is a thief, since he dares to stay here now, it shows that his mental quality will be very good."

"But when you look at him, he sweats on his forehead, the corners of his mouth twitch, and his whole body trembles. What do you think is a good quality in your heart?

"Professor Qin, these things are not evidence. A clever thief can completely disguise." Chen Long said.

It is true that he agrees with Qin Luo's first point, but he does not agree with the second point.

This is entirely Qin Luo's own reasoning, and there is no evidence to support it.

Without answering Chen Long's question, Qin Luo turned to look at Lu Zhiqiang, and asked seriously, "Did you steal the sample?"

"Professor Qin, I'm really not..." Chen Long said with a wry smile.

Lu Zhiqiang has a clear understanding of himself. He is a salted fish through and through. It is so easy for him to stand up.
