"Captain, where are your glasses?"

Huang Lili looked at Guan Feng suspiciously.

I remember the captain was wearing glasses when he entered the dormitory just now, how come he disappeared when he came out?

Guan Feng waved his hand and said, "That's not important! Let's wait for news from the communications department."

Huang Lili asked, "Do you think Chen Jin will call?"

Guan Feng nodded and said, "It's not just a feeling! It's a certainty. We've already laid out our plans and disrupted their order. Do you think Chen Jin can still believe the one Chen Zi'ang sent? In the prisoner's dilemma, he will definitely communicate with Chen Zi'ang."

Huang Lili asked, "But what if it's a different number?"

Guan Feng said, "Other numbers don't matter. I left a recorder behind when I left."

Huang Lili suddenly realized and said, "No wonder your glasses disappeared, Captain. Are you going to use the excuse of looking for your glasses to go back and get that tape recorder?"

Guan Feng smiled but didn't say anything.

Huang Lili only knew that the glasses had disappeared, but she didn't know that the smart glasses were actually a recorder she had left behind, and that it could even transmit Chen Jin's voice directly into her ears.

For example, Guan Feng could hear Chen Jin pacing back and forth, aided by bone conduction.

Seemingly having made up his mind, Chen Jin dialed a phone number.

Those sounds echoed clearly in Guan Feng's mind.

This feature is absolutely invaluable in case investigation.

And at this time.

Wang Xun whispered a reminder: "Captain, I'm afraid the prosecution won't support this method of evidence collection, right?"

Guan Feng nodded and said, "I didn't expect them to support me. I just wanted to confirm the next investigation method. Well, the important thing is still the test results from forensic doctor Qin. Once it's confirmed, we'll make the arrest immediately. We'll search based on the clues. I don't believe we won't find it."

"clear!"

Wang Xun breathed a sigh of relief.

It's obvious that someone like Guan Dui wouldn't make such a logical error. If the other party dared to use him, there must be some reason.

At this moment.

Ring ring!

A ringing bell, like a signal flare, broke the dull atmosphere.

Guan Feng took out his phone and saw that it was a call from forensic doctor Qin. He immediately answered and asked, "Forensic doctor Qin, do you have any results?"

Qin, the forensic doctor, nodded and said, "Based on the tests on the victim's blood and the examination of the degree of muscle spasms, I believe that the deceased must have inhaled ether-like gases before his death, which would have led to these changes."

Guan Feng asked, "Would inhaling this gas cause an instant loss of consciousness?"

Forensic doctor Qin said, "It depends on the dosage. With a large dosage, it's almost impossible to pass out without touching it. There was a short video that used this kind of gas to depict the horror of human traffickers."

Guan Feng suddenly realized.

He had seen similar videos before.

The trafficker covered the victim's mouth and nose with a handkerchief, and the victim immediately collapsed to the ground.

Guan Feng asked, "Old Qin, now that you mention it, I suddenly remember. This gas must be extremely volatile, right? How long would it take for it to completely evaporate?"

"Ether gases are indeed highly volatile. Generally speaking, under appropriate concentrations, they will completely evaporate in five to ten minutes," said forensic doctor Qin.

Guan Feng nodded.

At the time, Liu Yang was drunk. Five to ten minutes of evaporation time would have left some residue, which could have likely caused him to fall and land on the faucet.

The only uncertainty right now is...

What exactly was in the urinal that made Liu Yang go over to take a look?

Guan Feng said, "In that case, thank you, Forensic Doctor Qin. I'll take my people back immediately for further investigation."

Hang up the phone.

Guan Feng was about to speak.

The voice coming from the smart glasses startled him.

"is that so?"

Guan Feng frowned slightly.

He looked at Wang Xun and Huang Lili, his tone somewhat stern, and said, "Notify Sheng Guo to head east and prepare to make the arrest; notify the officers on duty on the first floor to prepare to cooperate with our operation; notify Captain Chen that the footprints on the outer wall can be extracted!"

"There are more than three perpetrators this time. We must ensure accurate arrests and not give any opportunity to tip off the perpetrators. All units must maintain close communication."

"receive!"

"receive!"

Both realized that Qin's call was no small matter, so they became extremely alert and began to notify their respective units to take their positions.

Five minutes later.

Everyone gathered in the restroom.

Guan Feng briefly explained the situation, then instructed the others: "Wang Xun, take your men to the next room and arrest Chen Zi'ang; Sheng Guo, and this comrade, you and I go to Chen Jin's room. Remember! He's most likely a suspect. Protect yourselves while you're making the arrest, and don't get hurt!"

"clear!"

Everyone nodded in agreement.

An arrest operation was launched.

......

At the entrance of Chen Jin's dormitory.

Knock knock knock!

Guan Feng knocked on the door.

Who is it?

Chen Jin opened the door with a somewhat gloomy expression, but when he saw Guan Feng and the others standing at the door, he instantly switched to a smiling face and asked, "Officer Guan, what can I do for you?"

Guan Feng shook his head and said, "It's nothing! I left my glasses here just now, did you see them?"

Chen Jin asked, "Glasses? I don't see them?"

Guan Feng said, "I put it next to the cabinet, let me find it."

He then pushed open the door and went inside.

Chen Jin's hand, hidden in his sleeve, twitched slightly as he slowly moved closer to Guan Feng, seemingly ready to fight to the death at any moment.

But the next second.

He noticed a pair of glasses had appeared on the cabinet, and he breathed a sigh of relief. He then pressed the knife down further and withdrew it to his wrist.
