The digital Zhong Tian was following the murderer, watching the murderer walk out of the unit building, subconsciously wanting to follow him out, but he encountered an invisible barrier and was bounced back.

Grandmaster-level space conception is an idea based on the clues you have already mastered.

Not having unlimited tracking capabilities.

The digital Zhong Tian was watching the murderer who disappeared in the community, and his figure flashed and gradually disappeared.

...

On the large balcony.

"call..."

Zhong Tianzheng breathed, came to his senses, looked at the space left on the ground of the room again, and continued walking along the large balcony.

This balcony connects to the entire large flat floor, and along this balcony, it can lead to any room.

Zhong Tianzheng also found that the space left on this balcony was obviously much more than indoors.

Leave it blank...

Zhong Tianzheng's eyebrows were deeply locked, and he opened the door connecting to the master bedroom, entered the master bedroom from the balcony, and walked through the master bedroom to the bathroom.

Chen Mengxi just arrived at this time and was sorting out his equipment.

Zhong Tianzheng looked down at Chen Mengxi squatting on the ground: "Are you late?"

"Well, there's a bit of traffic jam on the road."

Chen Mengxi did not look up.

"Okay, the result will come out later. Just send me a message."

Zhong Tianzheng nodded and took Ao Xiang out.

There was not much information left on the scene. Li Yiguang's cause of death should be very similar to what he inferred. This time of death should be exactly the same as Xiao Zhang's guess.

Enter the elevator.

This elevator is relatively high-end.

On the entire elevator panel, there are only buttons on the first floor and the negative first floor.

As for why there is no second floor, it should be that this is a large flat floor, with only one household on one floor, and one floor of the underground garage in each building is enough.

On the top of the button.

It is a high-definition OLED display with a face-scan interface and other operation buttons displayed on the display.

The display is a camera.

On the edge of the display is the sensing button of the access control card.

If the owner goes upstairs from downstairs, he or he or he or he or he or he or he or he or she or he or she or he or she or he or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she or she

After a brief weight loss, the two of them came to the first floor.

When the first floor elevator comes out, there is a fire passage opposite. The fire passage is blocked by a fire door, and the fire door is still a face-scanning and card recognition system.

If you come out of the fire door of the fire passage, just reach out and push the door.

Zhong Tianzheng had a special understanding of the security environment of the community.

In the community, the security facilities are very complete.

When outsiders enter the community, they must register.

In addition to personal information, you will also ask which unit building and which household owner will go to and how long it will take to go.

Then, they will make an indoor call from the owner and confirm with the owner before they will be released.

This is the first level.

Downstairs of each unit building, a separate security guard is specially equipped. The essence of their daily work is: stand in front of the concierge desk at the entrance of the unit building, receive the owners and are responsible for inquiring about each visitor entering the unit building.

Of course.

The residents and security guards in the unit building basically remember and recognize them. This is a basic work knowledge reserve.

It's almost the same as the question at the door.

When you ask the visitor's location and time, you will then call the entry phone again and confirm with the owner again.

After the owner confirms, the security guard lets you in.

The security guard opens the door of the unit building, and then the security guard connects to the owner when the call is operated by the elevator.

The owner presses the elevator switch indoors, and the visitors enter the elevator, and the elevator automatically rises to the owner's floor.

This is the second level.

The entire security environment is definitely one of the best.

Even the security guards in the community cannot enter the floor without the permission of the owner, unless the leader with higher authority comes.

Zhong Tianzheng and Xiang came to the entrance of the unit building.

The security guards in this unit building are being asked about the situation by colleagues.

Zhong Tianzheng was not in a hurry. He had been indoors for a long time just now, and the smell of blood was a bit strong, so he reached out and lit a cigarette and wrapped it up.

One cigarette ends.

The questions here are almost the same.

Zhong Tianzheng put out the cigarette butts and walked upstairs.

"Brother Zheng."

The team member handed him the inquiry record.

Zhong Tianzheng took it and quickly looked at the inquiry situation on the record, and basically understood the situation on the scene.

Zhong Tianzheng picked up several important question points to ask: "When the visitors came in, did you have any normal identity query?"

The Demon Eye observed the young security guard in front of him, not leaving any details.

“I’ve asked, and I’ve all registered.”

The security guard spoke very quickly and explained urgently: "This elevator can only be reached by the owner. The owner himself also had a video conversation with the visitor before the call to enter the house."

In such high-end communities, except for a murder case, the consequences are very serious and cannot be afforded by him, a small security guard.

Zhong Tianzheng was not confused about this topic: "You describe what the visitor looks like, and what is the purpose of his going up when he was registering."

Judging from the security environment of this community, if the murderer can go up, the owner must agree, and it has nothing to do with the security guard.

"He said he was repairing electrical appliances and went up to repair the TV for the owner."

The security guard explained: "As for his appearance, he is very ugly, with many spots on his face. This spot is very rare, so I have a deep impression of it. By the way, he is wearing a hat."

Very ugly?

Zhong Tianzheng frowned and ordered the team members: "Take him to the portrait department later and restore the murderer's appearance to see if he can make a comparison in the database."

Then Zhong Tianzheng asked again: "You haven't checked the canvas bag he carried up?"

The security guard shook his head and denied: "I checked, but no abnormalities were found." After saying that, he pointed to the two surveillance cameras at the entrance of the unit building: "The surveillance camera can see."

"Have you searched for him?"

Zhong Tianzheng asked the question, but this question is destined to have an answer.

A body search is definitely impossible.

"No."

The security guard shook his head and replied.

"Um."

Zhong Tianzheng nodded and did not ask again.

The security guard's operation was basically not omitted. The murderer was able to enter the floor of the deceased Li Yiguang, and the whole process was carried out with Li Yiguang's permission.

The key point still lies in Li Yiguang.

At this time.

Xiao Zhang came back from the property: "Brother Zheng, I have seen the surveillance camera in the corridor and can see the front face."

After saying that.

He took out his mobile phone and showed the screenshot of the surveillance to Zhong Tianzheng: "In addition, he has contacted the traffic management department and requested to view the surveillance screen of the street outside the community. He has sent someone to negotiate and track the murderer's route after he left."
