The night after Qin Han drove Xiao Sheng away.

In the middle of the night, the power suddenly went out.

The indoor environment system stopped, and Qin Han was immediately awakened.

What is an Indoor Environmental System?

Indoor environment system, as the name suggests, is a system that controls the indoor environment, including temperature, humidity, ventilation, and a series of equipment.

It's like an air conditioner for an ordinary home, but it's only a small part of the indoor environmental system.

"There's a power outage, and the backup power supply system isn't activated?" Qin Han frowned slightly.

The main power supply system of the estate is the city's power supply network.

In addition to the main power supply system, there are two backup power supply systems, each of which can provide 24-hour electricity to the estate.

All the equipment in the estate is regularly maintained, and even if there is a problem with the backup power system, it is extremely unlikely that two sets will fail at the same time.

"Something happened!" Qin Han immediately rolled over and got up and quietly left the bedroom.

Soon he found out that the manor had been invaded.

The problem is that the manor's security system is down, and the security personnel don't seem to be responding, and it's clear that it's not ordinary people who have invaded the manor.

Qin Han was just about to go out, but stopped again.

He remembered Chu Wanting, Chu Wanting was just an ordinary person and didn't have much ability to protect herself.

If Qin Han goes out now, if someone breaks in while Qin Han is out, Chu Wanting is very likely to have an accident.

Thinking of this, Qin Han immediately went straight to Chu Wanting's bedroom.

When Qin Han arrived, Chu Wanting just opened the door and came out, and the indoor environment system was shut down, which also made Chu Wanting wake up.

"Why are you here?" Chu Wanting looked at Qin Han.

"Listen, no matter what happens, don't panic, I'm here." Qin Han said to Chu Wanting.

"What the hell is going on?" Chu Wanting also realized that the power outage was not normal.

"It's not a big deal."

"Don't lie to me, something must have happened, you see that the phone has no signal." Chu Wanting took out her mobile phone and showed it to Qin Han.

Of course, Qin Han knew what was going on, and the signal was blocked.

Obviously, the people who broke into the manor at night carried signal blocking equipment to block the mobile phone signal and prevent Qin Han from using his mobile phone to get in touch with the outside world.

"It's possible that someone has broken in, but don't worry, it's going to be fine."

Rumble!

While the two were talking, they suddenly heard a muffled noise, coming from underground.

Qin Han instantly understood that the basement had been invaded.

The basement of the manor is a well-built treasure room, which contains many antiques collected by the Qin and Han dynasties, as well as other important materials.

When building this basement, Qin Han can be described as well-intentioned.

The outer layer is made of reinforced concrete with the highest strength.

The middle layer is a foot thick of special steel.

Memory, also made of special materials.

The only one that can enter and exit is a door, which is specially customized by Qin Han, and only he can open it.

In addition, it can only be broken by brute force, but this door is up to a foot thick and is also made of special steel, so it is very difficult to open it violently.

Qin Han guessed that the muffled noise just now was someone using blasting methods to try to open the door of the basement.

Boom!

Two more muffled noises followed, one more intense.

Qin Han knew, it must have been the first time he didn't open it, so there was a second time, and even a third time.

"With such a big movement, the security personnel should be dispatched, right?" Qin Han was very dissatisfied in his heart.

His manor was actually invaded, but the security personnel didn't react, and the power system was cut off, so there must be an internal response.

Chu Wanting also guessed the source of the loud noise, and couldn't help but grab Qin Han's arm.

After all, she was just an ordinary person, and she had never experienced anything like this.

"Don't worry, what they want is antiques, we won't be in danger..."Qin Han comforted.

He really wanted to rush out now and clean up the intruders.

With his force, as long as the other side does not use weapons of mass destruction, there is no need to worry about danger.

But he didn't go out in the end, because Chu Wanting needed his protection.

Compared with cleaning up those people, Chu Wanting is much more important.

Finally, there was a noise in the courtyard, and the security personnel were finally late, which made Qin Han breathe a sigh of relief.

Although the door to the basement is very strong, it can't be blown open in one or two blows, but if it is blown up too many times, it will be blown open sooner or later.

Ten minutes later, everything was quiet.

Then there was a knock on the door and the power system was restored, apparently the intruders had been chased away or caught.

"You go back to the room first, and don't open the door if it's not me knocking." Qin Han asked Chu Wanting to go back to the room, and he walked out to open the door.

Looking out of the door through the visual system, Qin Han was relieved.

Outside the door were the security guards of the manor, and there was more than one, waiting at the door.

"Mr. Qin, are you okay?" Seeing Qin Han open the door, the security personnel breathed a sigh of relief.

"I'm fine, but what happened today, do you want to give me an explanation?" Qin Han asked very unceremoniously.

The power system is flat, the two sets of backup power supplies do not work, and they did not detect the invasion at the first time, they are really derelict in their duties.

"Mr. Qin, don't worry, I will definitely find out and give you a satisfactory explanation." The team leader of the team had a look of shame on his face.

After a quarter of an hour, the danger is eliminated.

Qin Han came to the basement and found that the basement was in shambles.

In the most serious damage, the traces of the explosion can be clearly seen outside the door to the treasure room.

Despite three blasts, the door to the treasure room was not blown open.

Qin Han breathed a sigh of relief, it was good that the door was not opened.

Letting the others withdraw, Qin Han tried to open the door of the treasure room, he was worried that the door would not function in the three explosions just now.

The door opened smoothly and did not fail.

Qin Han entered the treasure room to inspect and found that there was no loss in the treasure room, and the powerful blasting outside the door had no effect on the inside of the door.

Qin Han nodded with satisfaction and returned.

He returned to the living room, grabbed a tablet, and looked at the monitoring data, including two sets of backup power supplies.

After reading it, Qin Han's face was gloomy.

"Zhang Dongkang, you come over right away." Qin Han called by phone.

His estate has two security consultants, one of whom is Zhang Dongkang, who is mainly responsible for the equipment, including two sets of backup power supplies.

"Mr. Qin, are you looking for me?" Zhang Dongkang walked in, a short man in his forties.

"When the accident happened, both sets of backup power supplies failed, do you have anything to say?" Qin Han asked.

"Someone destroyed the line, I have repaired it just now, and I promise that there will be no similar accidents in the future." Zhang Dongkang said.

"Do you know who broke it?"

"I don't know, the monitoring system for the backup power is turned off."

"Zhang Dongkang, are you satisfied with the salary I gave you?"

"Satisfied, of course satisfied, the salary you gave me is the highest in the industry."

"Is that where I can't stand you?"

"Of course not, how do you say that?"

"Because you destroyed the backup power, I kept thinking, what is your motive for destroying the backup power? Can you tell me? ”

"Mr. Qin, this is no joke, how could I destroy the backup power supply?"

"I'm not kidding, the surveillance system was actually destroyed, but you were seen when you destroyed the line of the backup power supply." Qin Han sneered.

Of course, it was not that Zhang Dongkang was seen, but that there were two sets of monitoring systems for backup power, one bright and one dark.

What Zhang Dongkang knows is only the monitoring system on the surface.

There is also a hidden monitoring system, which only Qin Han and a very few people know.

So Zhang Dongkang thought that the monitoring system was turned off, and the blatant destruction of the circuit was filmed by the secret monitoring system.

When Qin Han checked the monitoring through the tablet just now, he found that Zhang Dongkang had destroyed the power supply.

"What?" Zhang Dongkang's face turned white.

"Say, why destroy the backup power supply?"

"I..."Zhang Dongkang looked at the door.

"Don't look at the door, do you think you can run?" Qin Han sneered.

"I can't run..."Zhang Dongkang smiled bitterly, as a staff member of the manor, of course he knew how strong the manor's security system was.

As long as Qin Han gives an order, let alone a person, not even a fly can fly out.

As for the negligence of the security personnel today, they did not find the foreign intruder, it was he who did it, otherwise the foreign intruder would never have succeeded.

"Why don't you want to say it?"

"I said, Mr. Qin, it's all because I can't live with you, when my wife and son were traveling abroad, they were controlled by a group of mysterious people, they threatened me, if I didn't do what they ordered, they would kill my wife and son, I was really forced to helpless." Zhang Dongkang knelt down.

Qin Han frowned slightly, of course he knew that Zhang Dongkang's wife and son were traveling abroad.

Just a week ago, he arranged it as a benefit for the employees of the estate, along with a number of other employees who were traveling abroad.

The other employees have returned, but only Zhang Dongkang's wife and son have left the team.

Qin Han didn't pay attention to it at the time, he just thought that they were crazy and wanted to continue to play for a while at their own expense, but they didn't expect to be kidnapped.

"What the hell is going on today?"

"I don't know, and they won't tell me."

"I understand your situation, but how can you ask me to forgive you?" Qin Han frowned slightly.

"I can help you find them."

"How?"

"When I was picking them up, I put a miniature locator on a person and I could track it with my tablet."

"Okay, if what you're saying is true, I can consider letting you go." Qin Han nodded.

In any case, Zhang Dongkang will definitely not be able to continue to use it.

But you can't kick him out now, if you kick him out now, it will be to tell others that Zhang Dongkang has been discovered.

Not only will Zhang Dongkang's wife and children be in danger, but it will also hinder Qin Han from making his next plan.

Considering this, Qin Han decided to keep him behind and let people monitor him, which was equivalent to temporarily placing Zhang Dongkang under house arrest in the manor.

"Thank you, look, this is them, they are moving fast..."According to Qin Han's request, Zhang Dongkang located the person who broke into the manor.

On the map of Tsurujo, the small red dot located is moving quickly along the highway towards the suburbs.

Depending on the speed at which they are advancing, it will take less than half an hour for them to reach the outskirts or turn onto a highway.

At this time, Zhang Dongkang's phone rang.

"It's them..."Zhang Dongkang looked at the caller ID, and then said to Qin Han.

"Answer the phone, you should know what to say..."Qin Han knew who they were in Zhang Dongkang's mouth, the one who broke in tonight.

"Why are you calling me at this time? Do you want to kill me? Zhang Dongkang answered the phone and said in a reproachful tone.

"Hmph, surnamed Zhang, don't you want your wife and son anymore, do you want them to die?" The person on the other side of the phone shouted angrily.
