Gong Suyan has already found the special detection vehicle used that year in the warehouse.

After not using it for decades, he found technicians and spent an afternoon and night repairing and debugging it.

Finally available.

There are four detection vehicles in total, patrolling the roads in the capital at the same time, and diverging to the surrounding areas, one in each direction, southeast, northwest, and northwest.

After preparing everything, Qiao Ran, Zuo Chenye, and Gong Suyan boarded the special exploration vehicle heading south.

Because, they speculated, the south was the most likely.

Next, the detection vehicle sets off.

Zonal blackouts begin.

Gong Suyan was on the road, paying full attention to the detected blind spots.

"Record all blind spots." He ordered the accompanying technicians he brought with him.

Zuo Chenye watched the road and kept in touch with the General Administration of Electric Power in real time to conduct investigations based on the power outage area.

This is a complex and long process.

Maybe two hours isn't enough.

Even if the address is screened out, they still need to check it for a long time.

It's unlikely that it's in the urban area. They will conduct a simple investigation.

The main focus is on suburbs and mountainous areas.

"Here, check carefully." Qiao Ran pointed to an area with dense mountains.

"Look, the signal here has disappeared. This area is inhabited, not entirely no man's land." Zuo Chenye pointed at the display screen.

Gong Suyan frowned, "It doesn't look like it. It may be due to insufficient signal caused by the mountainous area itself. We need to screen again."

Qiao Ran bit her lower lip, couldn't help clenching her fists, and looked nervous.

During the time when Qiao Ze'an was missing, she couldn't eat or sleep well. She became more and more anxious.

Seeing this, Zuo Chenye stretched out his arms and hugged her tightly, comforting her gently.

"Don't worry. There will be clues."

"Yeah." Qiao Ran nodded weakly.

Next, they investigated closely.

Time passes quickly.

the other side.

After Qiao Ze'an finished programming, he tried the cracking program and was pleasantly surprised to find that the entire villa actually had an internal network, which might be used to control all smart devices.

Generally speaking, this kind of internal network is highly encrypted and difficult to invade.

But as long as there is a program, there are loopholes.

Qiao Ze'an tried to hack into this internal network.

After staying up late for too long, he was a little sleepy and kept yawning. Afraid that he would fall asleep accidentally and forget to put the microcomputer away properly, he pricked his arm with a needle.

A slight pain irritated his nerves.

Remind him that he must not fall asleep.

At about half past four, Qiao Ze'an discovered that the guards did not come up to patrol.

He speculated that the guard might have fallen asleep.

People sleep the most deeply and sleepily between 2 a.m. and 4 a.m., and are at their weakest defenses. Therefore, thefts and many arrests are carried out at this time.

After more than four hours of hard work, Qiao Ze'an has written the program.

He gave it a try and should be able to complete the intrusion into the internal network within half an hour.

However, he was worried that once he invaded the system, it would cause abnormalities in other control ports.

This resulted in his operations being exposed.

He wasn't sure, so he didn't dare invade easily.
