Blue Star World, Shard City, Underground Shelter.

An incomparably deep underground road, and I don't know where it leads, as if there is no end.

In fact, it was originally an underground river, and it can be seen from the water intake facilities left by humans next to the underground river that humans used to draw water from this underground river after the disaster.

But now, the underground river has long since dried up, and there are no water molecules left.

This underground river is very close to the large human shelter, and it can be said that the shelter was built on the basis of this underground river.

One side of the river has been built with a smooth road that follows the direction of the underground river, and it is not known where it leads.

The robot An An drove about three kilometers with Xu Ran, and the underground river was intercepted and stopped, and a large water supply facility was built on the side.

The river has been dug very deep and artificially widened, like a large reservoir.

At the bottom of the river after it dried up, Xu Ran found a large number of animal and human bones, which were so dense that people looked a little numb.

However, the bones of the corpses looked very different from the remains left behind by humans on Earth, and they all had a metallic color, as if they had been transformed into metal bones by the assimilation of molecular structure and metal elements.

There are probably tens of thousands of corpses and bones, and Xu Ranyu was panicked when he saw it, but he didn't look at it again, so he turned his attention elsewhere.

There is also a large elevator next to the facility, which is naturally unusable, but there are also relatively gentle stairways nearby.

After going up the staircase, there is a large underground factory.

The equipment used in this factory is much more advanced than that on earth, and there are several areas such as sewage treatment areas and clean drinking water treatment areas, mainly water treatment.

Walk through this area to another area separated by a section of the wall, which, judging by the equipment left behind, was once a food processing area.

The underground factory was very large, many times larger than the previous underground shelter.

In addition to the food processing and water treatment areas, there are also areas for the processing of daily necessities and various household utensils, all of which are closely related to human survival using the most advanced industrial equipment.

When Xu Ran took a tour bus through these areas, he saw several industrial robots in a state of curled up.

As An An reported, there are indeed eight industrial robots with various specific characteristics and styles left in a large area at the bottom.

However, the underground factory extends beyond the depth and width of an area of one kilometer underground.

After a few hundred meters of circular ramp steps, there are still factory facilities, but the area occupied is relatively small, and they are all processing equipment in various fields related to facility construction, such as electronic equipment and equipment, materials and equipment, chemical products, metal products, precision instruments, vehicle manufacturing, power engines, aerospace, communication instruments, etc...... Wait a minute.

Each area is a miniaturized production line, which is relatively dense, involving various fields of human progress and development.

Further up, there was a local area about 500 meters away from the surface, where Xu Ran finally found a processing and manufacturing production line belonging to industrial robots, and couldn't help but be overjoyed.

If the industrial production line here can be utilized, Xu Ran's idea of manufacturing those simple industrial robots is not an extravagant hope, it is completely achievable.

But the premise of all this is that there must be energy support.

But why don't there be energy and power facilities in these areas?

Because of this question, it also diluted Xu Ran's excitement about discovering the robot manufacturing line, so he began to continue to climb to the surface to investigate.

Finally, Xu Ran took the tour bus to the area at the foot of the half of the mountain, which was about 300 meters away from the surface and about three kilometers away from the length of those large factories.

However, what made Xu Ran feel like crying was that there was a piece of it that was in a state of collapse, and most of it had already been buried by the collapsed rocks and soil, causing this area to suffer very serious damage and destruction.

At the edge of the damaged and destroyed area, Xu Ran also found several industrial robots that were also damaged, which seemed to be scrapped and could not be used, otherwise An An would have been included in the statistics.

Fortunately, there are some large power generation facilities that have survived in the areas that have not collapsed.

Although it is only a part of the whole, it is not possible to generate enough power to the entire fragmented city and underground factories and shelters, but if it is used, it should still be possible to supply local power.

In addition, the power plant here only provides power for the entire underground factory and underground shelter, and it is estimated that it will not involve the power supply of the entire city.

When Xu Ran searched in the factory area of the fragmented city, there was also a medium-sized and large-scale power plant that could supply electricity to the entire city, which was completely preserved.

When I think about it, the depression in my heart disappears.

Even if it were to be destroyed, it would only be a matter of time before it was restored as long as the surface power plant was fully utilized and there were enough labor resources.

However, it may be very difficult for Xu Ran in the early stage.

Because he does not have enough labor resources, it is extremely urgent to search for robots to find them.

The more robots that can be utilized, the more labor resources will be fully available, and the more things can be done, which is a virtuous circle.

On the contrary, even if Xu Rankong has the resources of the entire fragmented city, but without the labor and helpers to work, he is the only one, and it is difficult for the Qiao woman to cook without rice, and she can't do anything, so she can only be a porter for the earth.

Therefore, at present, the ten industrial robots reported and discovered by An An must be used first.

Thinking about it like this, Xu Ran didn't have the heart to explore this underground factory anymore.

Because half of the underground power plant had collapsed, and the passage to the surface had also collapsed and been destroyed, Xu Ran could not return to the surface through there, so he had to return the same way.

After returning to the surface and returning to the central building of the Fragmented City, Xu Ran sat on a sofa and thought carefully.

When the robot An'an is full of energy, it can activate and initialize two industrial robots and crack the self-destruction program of artificial intelligence.

To make use of the ten industrial robots, this requires Xu Ran to continuously replenish energy for An An, and at the same time, to replenish the energy for the ten robots that have restarted initialization and can work.

So in the early stage, Xu Ran had to transport a batch of fuel oil back and forth from the earth, and work continuously through the small fuel generators found here to replenish the energy consumed by those robots.

Wait until the ten robots can work normally, and then build a few more heavy machinery that can intelligently control the coal resources in the mountains, and then transport them to the power plant for thermal power generation, and strive to make part of the power plant equipment operational, and separately supply local power to the building and the underground factory.

After thinking of this, he probably formed a preliminary development plan in his heart, so Xu Ran called the robot An An over and asked: "An An, how is the survey of the distribution of energy and mining in this fragmented city, and can the power plant be operational?"

It's just that An An's answer suddenly made Xu Ran's fragmented city development plan brewing into nothing.
