The efficiency of the factory is not good, and even the security guard at the door seems lazy.

When Mu Zi and Qu Mingjun arrived, the security guard didn't even ask, and they took a nap in their security booth.

It may also be that when Qu Mingjun is wearing a suit, he thinks that the other party is a business partner of the boss. Anyway, as long as it doesn't look like a sneaky person, the security doesn't matter.

Qu Mingjun and Mu Zi are both here for the first time. Although they have read the case files, the on-site inspection is a different feeling.

Qu Mingjun looked for the place described in the document, pointed to the camera above the gate, and said to Mu Zi: "It should be this. There are two cameras on the gate, one facing inward, one facing outward, and one facing outward. The camera can just capture the situation on the road."

Mu Zi raised his head, carefully checked the camera, and then looked at the road in front of the factory gate with a thoughtful expression.

Qu Mingjun ran to the security booth by himself and asked the security guard inside: "Where is the trash can here?"

The security guard glanced at him inexplicably and pointed aside.

Qu Mingjun looked over, saw the trash can by the wall, nodded and thanked: "Oh... I saw it, thank you."

Mu Zi was puzzled, "Why are you looking for the trash can?"

Qu Mingjun was taken aback, and then asked her: "...Should we not dig through the trash?"

"Why go through the trash?" Mu Zi was even more confused.

Seeing Mu Zi's reaction, Qu Mingjun wondered if he knew it was wrong, wouldn't he need to go through the trash this time?

It's embarrassing, he is ready even for his gloves...

He murmured: "I thought...will be the same as last time..."

"Let's watch the surveillance video." Mu Zi didn't hear what he said, and his thoughts at the moment were all on the case.

The two found the security again and asked to view the surveillance video on November 2.

Probably because the police came to the factory to check the surveillance from time to time recently. There was no ripple on the security guard's face. They took them to the office with a wooden face and called up the November 2 video.

"This is a pause, press this to fast forward... Now, the USB interface is here. If you want to copy, you can also use Bluetooth. Don't touch other files." The security guard explained and went out lazily.

The surveillance video on the day of the incident was used as one of the evidences and was collected by the police. There is a backup in the case file.

Now, Mu Zi and Qu Mingjun are in the factory, watching them again at fast forward speed.

During the estimated time of the incident, no vehicles passed by the factory.

The two of them looked at the video image displayed on the screen and were silent at the same time.

After a while, Qu Mingjun's brain suddenly flashed, saying: "Xia Chenan said that Zhou Xuanxuan got into the car at about 5:30 in the afternoon. When the police checked it, they looked at the surveillance record at about 5:30, but is it possible? later?"

Qu Mingjun had an idea in his mind and felt that he had never been so smart!

"The prisoner may have parked his car halfway! He knows that there is a surveillance camera ahead, so he deliberately staggers the time, such as... Wait until 8 or 9 in the evening, and then drive over after dark!"

Mu Zi thought, "There is such a possibility..."

Qu Mingjun can't wait to drag the video later, looking forward to discovering new clues.

However, the results were disappointing.

Still no vehicles passed. Not only at eight or nine o'clock, they kept fast-forwarding to see the next day, and there was still no traffic passing by.

Mu Zi thought for a while and said, "Look at the surveillance video inside the door."

Qu Mingjun was stunned, and couldn't help saying: "But the camera facing inward cannot see the highway in the monitoring range."

"You don't have to see the highway, as long as there is something unusual, it may be a clue." Mu Zi replied.
