The original underground world was dead silent, even closed.

It was Xu Ran who discovered the robot An An, and put An An back into the fragmented city after activating it, and after An An's search, he finally excavated the dead underground city.

With an underground city, there is also a natural shelter where you can avoid the direct harm caused by the mysterious purple light, so there are not many scruples about the development of the underground city.

Therefore, after the underground shelter and the underground factory were connected, it was named the dungeon by Xu Ran, and the dark underground world already had some vitality and vitality.

First of all, all the 200 robots that Xu Ran searched for were reactivated and opened in an extremely violent way such as An An's re-hardware formatting and artificial intelligence cloning and transplanting, and they were already able to put into work one after another.

The help of the 20 tons of fuel oil that Xu Ran got back from the earth can be said to be very huge.

With the uninterrupted and continuous power supply of the fuel supply generator sets, the hardware formatting of the robot and the cloning and transplantation of the AI are progressing very smoothly.

After testing that there were no problems, An An was the first to get the 100 labor-type robots on a large scale, and they will be the backbone of the main force of various operations in the future.

Of course, the bottom layer is naturally the quality, as well as the industrial robot with the lowest level of artificial intelligence, pure coolie operation.

However, for the time being, these 100 labor-type robots still have to be heavy coolies for a period of time, and when they are put into work, with the dozen or so industrial robots, the cleaning of part of the collapsed area of the underground power plant will be much more efficient.

Xu Ran also didn't know how An An customized the classification of artificial intelligence, what kind of logical distinction was used, or whether the rules and permissions opened were different.

However, An An rated the industrial robot with the primary artificial intelligence level at the bottom as F-level, and when it came to the labor-oriented robot that reflects the advanced industrial manufacturing level, the rating actually reached C-level, which directly crossed the distinction between two levels with industrial robots.

The rest of the entertainment, computing, housekeeping, maintenance and auxiliary robots are classified into the B-class range.

As for An An's own rating, it is only an A grade, and as for the level of the highest grade, An An has collected limited information and cannot define it.

Xu Ran feels that this is not the point, and the division of levels is only to facilitate the numbering and unified management of the work that the robot is responsible for, and the logic of artificial intelligence will run strictly and orderly, which can play the greatest role and avoid some unnecessary waste of resources.

For example, cleaning up the collapsed part of the underground power plant is the work goal that needs to be completed in the first phase of Xu Ran's customized development strategy.

An An follows Xu Ran's order to customize the working standards of artificial intelligence operation for the robot, and will be uniformly distributed in strict accordance with the hierarchical operation logic of artificial intelligence.

Xu Ran drove a tour bus to the underground power plant to inspect it personally.

The first to be cleaned out was the elevator shaft of the large elevator, an elevator shaft more than 400 meters deep, because the quality of the engineering inside the shaft is very high, and the downward filling of the collapsed area is only more than 100 meters deep at most.

After the landfill part of the area is cleaned up, most of the elevator shafts can still be used, leaving a hundred meters to the surface height of the damaged collapsed part, and after re-reinforcing some load-bearing areas, although the elevator is still unable to pass to the surface, but the road route is relatively gentle due to the relatively gentle terrain of the section, it is the situation of the slope, but it has been completely dredged to the surface, and this 100 meters can be changed to the road route to solve the transportation problem.

Otherwise, it is necessary to lead here from the entrance and exit of the underground shelter, and there is at least a distance of dozens of kilometers from the ground to the underground of nearly a thousand meters, and it is a waste of resources to repeat too many distances back and forth.

The section of 300 meters to more than 400 meters where the large elevator has been dredged and repaired, and then to the depth of 1,000 meters underground, the elevator can still run after the power is supplied.

However, in order to maintain the whole operation, the consumption of power resources is too tight, and the supply of oil-fired generator sets alone is far from enough.

So at present, after the repair of the large elevator, everything is to repair the underground power plant as the primary task, and the section where the elevator runs is only the section of the power plant facing more than 200 meters, and then the resources are transferred through those large trucks.

When a certain amount of resources are stored in the future, and the underground power plant can be operated smoothly to supply electricity, then everything will be revitalized.

As for the things such as broken rock and stones that are cleaned up, the robot does not consume resources to transport them to the outside, but finds a suitable open place in the current section and piles them up, and then slowly cleans them up in the future, and now it is mainly to save resources.

It is precisely under such circumstances that the clean-up of the underground power plant will progress very quickly, and gradually begin to expand to the surrounding area, and some of the main power generation facilities have been revealed.

Judging from the main power generation facilities that have been cleaned up, the underground power plant built here also has a separate set of water recycling treatment facilities, which is also designed in line with the principle of maximizing water savings, which is very clever.

Through robot analysis and annotation, this recycling treatment facility can divert a small amount of industrial wastewater and sewage discharged from other underground factory facilities here for treatment, and be fully recycled and reused in the power generation process, without causing a drop of water waste, which gave Xu Ran an unexpected surprise.

However, the surprise continues.

When we went to the planned resource concentration zone of the power plant, the robot cleared an area and immediately found that there was a large amount of ready-made coal stored there, which was very large.

Then through this resource storage belt, a line is crossed to the area where the power plant area connects half of the mountain, and even greater surprises follow.

According to the robot's report, the place connecting the mid-mountain area is completely connected to the coal resource points directly under the mountain.

That is to say, the coal resource point at a depth of 400 meters under the mountain is directly a ready-made coal mine, which is directly connected to the resource storage belt of the power plant, and the mined coal does not need to be transported at the cost of resources, and can be directly exported from the mine and transmitted to the power plant for use.

Even in the event of an oversupply, the coal can be mined for storage in resource storage belts, while continuing to expand underground space and harvest other mineral resources.

It seems that this power plant is designed to be built 400 meters underground, and it should be designed for the easiest and fastest use of the coal resource point.

From this, Xu Ran couldn't help but guess that the locations of other underground factories seemed a little strange to him, so was there something else among them.
