At present, An An has conducted a detailed search of most of the places and facilities in the entire fragmented city, and at most only found three small entertainment function robots under the ruins of several mansions, and two maid service robots with only inner metal skeletons left.

The three entertainment functional robots are all intact, and they can continue to be used after cracking the self-destruct program.

In fact, the two maid service robots were originally biological shells with metal skeletons inside, but after the disaster, the biological shells that mimic human skin have been damaged and lost.

But fortunately, the endoskeleton and those functional parts are still complete, if you don't care about its appearance, add energy to it and reactivate it, and after the self-destruct program is cracked, it can still be used normally, and An An can be transformed and installed with a metal shell as An An's assistant.

However, although the results of An An's search are not satisfactory, it is not without promising news.

Since the three newly searched entertainment functional robots and maid service robots were all found under the ruins of those mansions in the fragmented city, it means that the robots have not yet reached the point of universal popularity in the city before the disaster, and are still only the playthings of the rich or powerful, or the coolies in large factories.

The robot An An was also discovered by Xu Ran in the underground cellar of a luxury villa manor.

Then, in this underground shelter, since there is an area for the powerful and rich to be specially prepared, it is very likely that they will take refuge here and bring robots to serve them.

With such a speculation, Xu Ran became very interested in opening the metal gate and exploring the place where the powerful and rich took refuge.

After the two industrial robots were also fully charged, Xu Ran turned off the generators and added some fuel.

Have the industrial robots take a few generators to the innermost part of the shelter, which is closed off by a metal gate.

An An had already learned about the control facilities of the metal gate, and after the industrial robot forcibly broke the outer door of the room facility, he took the generator into the room of the instrument facility that controlled the door.

The metal door is indeed intelligently controlled, and there is a large control machine in the room.

After An'an sorted out the wiring of the control machine and the metal gate control system, in order to avoid the waste of generator power resources, he temporarily cut off the power supply line to other irrelevant facilities, and only reserved the power supply line for the metal gate and control facility.

After the wiring was done, it was adjusted according to the power supply index required by the gate, and the transformer and voltage regulator were found to connect to the generator, and then connected to the line of the control instrument, and An An turned on the generator.

When several generators are working at the same time, there is a power supply, and the control system light of the metal gate is lit.

An An started the self-test program of the control machine, cracked the boot password and login password, and after entering the system, it was easy to crack the intelligent system control password command.

In the end, it has undergone a self-evolution of artificial intelligence, and An An's artificial intelligence is very powerful, and it is very handy when doing these things.

When the control system of the metal gate was cracked by An An, An An just pressed a start button on the console, and the control system of the metal gate responded quickly.

Chirping!

Then I heard the extremely harsh sound of metal grinding from the transfer of dry mechanical gears, presumably because there was no lubricating oil.

However, after the command was activated, the metal door was still slowly opening, and the extremely harsh noise did not matter.

Eventually, the metal door finally opened.

Xu Ran asked An An if the control system was closed, would the door be closed, and An An said that once the control system was turned off or the power supply was stopped, the door would be automatically closed.

Xu Ran didn't want to do these tedious tasks every time he opened the metal door, it was too troublesome and a waste of resources, and the power resources in the early stage were very precious and had to be used on the blade.

But it's not impossible to keep the metal door open.

An An asked the industrial robot to find it, and I don't know where the industrial robot dismantled a few very large and hard metal load-bearing columns, and then used the most primitive way to push under the weak part of the metal gate, and at the same time stuck several mechanical gears.

When An An turned off the control system and stopped the power supply, he heard a bang, and the metal gate was about to fall slowly.

However, there are a few load-bearing columns at the bottom, and after the mechanical gear of the metal gate is stuck, it only falls for about ten centimeters.

After Xu Ran let the robot confirm that the gate would not suddenly crush the load-bearing pillar and fall down again, he took An An and the two industrial robot brothers into the refuge area.

In the end, it is a place prepared for the powerful, and the overall construction layout and decoration inside are very fine and beautiful.

Observed by searchlight, the area of this powerful area is not very large, about half of the civilian area outside.

In it, Xu Ran was able to see a lot of luxury goods that had been left behind, as well as all kinds of facilities and related high-end materials for enjoyment and play.

In addition, there are a large number of bones in many of the beautifully decorated houses.

It seems that the powerful people in this don't know what the reason is, they should be completely trapped in this.

It's not like Xu Ran didn't see a single corpse left on the surface outside, but all of them were concentrated in the big pit at the mouth of the underground river on the side of the underground factory, and there were tens of thousands of corpses.

The bones of the magnates here also have a metalized color, and they have also been homogenized by metal.

At first, Xu Ran looked at it and felt panicked.

But if you see too much, it's no wonder, even if you are a powerful person in life, after you die, you are just a skeleton that is no different from a beggar.

"Boss, discover the robots!"

Unexpectedly, he came in and explored an area of less than ten meters, and the robot An An gave Xu Ran a small surprise.

In the end, the robot has an electronic eye to scan, which is much more convenient than Xu Ran using the naked eye to find it.

Xu Ran followed An An quickly to a locked place like a storage room under a house, and saw a robot similar to An An, which was in a primitive shrinking state after running out of energy.

Xu Ran looked at the robot in front of him with a flashlight, which was also a robot butler, and it was still easy to identify.

Its quality and structure are the same level of robots as An'an, very sophisticated and advanced, and it should have been an imported product, unlike the low-level robot production line that can be produced by the underground factory here.

"Boss, discover the robots!"

"Boss, discover the robots!"

At this moment, Xu Ran didn't have time to observe the situation of the robot butler, and suddenly there was a report from two industrial robot brothers outside.

These magnates who were once trapped and died here did not disappoint Xu Ran, and it is estimated that every family that came here for refuge brought a robot butler who could provide them with a full range of services, and they should all have been left here.

Hearing this frequent report, Xu Ran couldn't help but grinned, and his heart blossomed.
