Compared to the satellites in the sky, drilling mountains and digging holes and building bridges looks very rustic, but once this huge project is completed, it will be the most pride.

How much is Lu'an's super-conductive power? The standard for level five is a guide area of ​​thousands of cubic meters. When he met Ji Liu, Luan tested his super-conductive power of about three thousand cubic meters. As for now, Luan cannot accurately calculate it, but the preliminary estimate should be more than five thousand and less than ten thousand.

It was not much used when laying the sky network. Most of the sky network lines have a diameter of only zero point one millimeter as thin as hair. One cubic meter can be laid for one million meters and one thousand kilometers. Lu'an consumed a total of 500 cubic meters of superpower to lay such a sky network in the sky.

The most densely packed line on this big network is only a distance of 300 meters, because the deviation of Luan's normal navigation on each channel is up to 100 meters. This big network gives initial positioning, and the gyroscope in the plane can also be carefully positioned. Therefore, it basically meets Luan's sky armed deployment.

This Tianwang can also transmit information. It relies on mechanical waves to spread information. With nine minutes of advance preview, it has practical value. However, at present, it is very inconvenient to rely on Tianwang to transmit information.

Because the skynet is mostly at an altitude of 500 meters. In reality, Lu An is on the ground. Even during the rehearsal, Lu An is mostly on the ground and cannot fly to the sky casually. Now Lu An’s rehearsal is nine minutes long. After taking off within these nine minutes, you basically don’t do anything next, and wait for the onlookers to ask for an autograph. This seriously affects his own efficiency in the rehearsal.

Therefore, it is necessary to establish a ground network. Moreover, the skynet can be connected to the ground network through landmark buildings.

If you get information from the ground network, you will not appear to be a maverick. If Lu An wants to read the information during the rehearsal, just stand a little, take out a nail from his pocket, wrap it with an unblocked film, borrow kinetic energy from the street cars, pierce the nail through dozens of meters underground, and connect the ground network. Such a small action will not be noticed. Even if Lu An finishes the calculation and raises his foot, someone will think it is already there. It should be left by rainwater erosion. As for how deep the hole is, in the nine-minute rehearsal time, no one will drill down with an excavator and follow the roots to investigate. As long as no one checks, Lu An can do other things during the rehearsal.

In this way, Luan can interpret shock wave information through his portable bubble computer and understand the situation of the aircraft cruising along the sky network.

Of course, the ground network is not just used to transmit information. Lu An thinks that he should also have a certain material transportation capacity, so he doesn't need to transport himself. He can fly anyway when he encounters danger. However, in normal times, if he can transport something the size of a can, it would be great to go to his position.

So Luan's plan is to plan pipelines and guide rails, as well as to set up storage points at individual points in the city.

The pipeline is a one-millimeter main pipeline, a zero-point five-mm pipeline. It is mainly used to transport powder particles. It is generally coal powder and metal powder (explosion is art, high temperature is achievement. The coal powder explodes, aluminum powder and iron powder ignites, and the fireball cannot be lost.) In Luan's plan, the main pipeline must use 42 cubic meters, that is, a 420-kilometer main pipeline is arranged to connect 400 main storage points. There is one within an average of 700 meters.

Each main storage point is forty meters underground, with multiple cavity groups inside, with a volume of eight cubic meters. The inner cavity wall is covered with unresisting film (note that it is a layer of film, not the entire cavity covering the superpower of conductivity.)

Each main storage point has a number of 16 to 27 sub-storage points. Basically, it is necessary to run a hundred meters and have an ammunition depot under your feet. Since escaping from the first generation, Lu An believes that fighting is to use everything you can use. If you can stab it with a knife, you don’t need to use a big fist. If you can use powder, you don’t need to bomb it with super powers.

In the plan, these sub-storage points have multiple pipes extending to the surface. Remember that there are multiple pipes. A water tower can have multiple faucets, and a storage point can have multiple pipes extending to the ground. Lu'an's ideal state can be found in this city for only 20 meters. There is a small hole in the diameter of a straw hole in the three-meter-high wall, which can bring the powder you want. As for why it is a three-meter-high wall? No one can touch the three-meter-high places. It can be arranged in the streets and alleys in a plain way. As for someone who sees these small holes that can only be inserted into straws in the cracks, he will not smash the wall under curiosity.

As for the number of pipes from underground storage points to the surface, the number of pipes is too large and the length is too large. Lu'an will not arrange them and maintain them every day to maintain them permanently. If they want to arrange them, they consume too much.

Because when you arrive at this place, you can use the frog sight to temporarily add an unblocked membrane to the last pipe. Then open it when needed.

It's like taking a bus home and taking a stop. Just walk back directly from the platform to the door of your house. There is no need to build an electric sidewalk to send yourself home.

Finally, these pipes are large in number, and they are large in diameter (the thickness of the straw). If they are always arranged, Luan's super-conducting power will not be enough.

Moreover, the temporary arrangement is very fast. When Lu An needs it in reality, he can send a preview to fly over and quickly pass the unblocked membrane of the pipes on the wall through the frog sight, and then spray powder on a large scale. In reality, Lu An doesn't even have to move. As long as he sees what he sees (what he sees in the preview), he can control the powder stored in the underground that is several kilometers or even ten kilometers away from the ground to flow out of the surface.

This is the pipeline plan in the ground network.

As for the guide rail plan, it can transport some gadgets, such as a piece of mooncake, a box of Yunnan Baiyao, a magnifying glass, a watch, and a telescope. These do not take up space, but cannot be carried with you, and it is very far away when you go home.

The purpose of transporting powder is to prevent accidents, but Lu An tried to save trouble himself.

Lu An said in a certain emotional state: "In order to build the pipelines for transporting powder, they have been excavated underground. Why not dig a larger one to accommodate a small box through it? After this small box is wrapped in an unhindered film, it can move to all parts of the city with little energy as long as it is leaning on this ready-made slide rail."

Although people come and go in this city, there are always dead corners. For example, the north side of a building (the side without the balcony). It is dark all year round. Only when you park your bicycle at work in the morning will you park here. Usually, it is as empty as the school corridor during class. Sometimes, these dark corners will be poured and urinated because people in the middle of the emergency cannot find the toilet.

The materials are exported, and there are ready-made. Every modern building has rainwater drainage pipes. Please note that the four corners of the building are rounded, with external pipes hanging from the roof to the ground. They are made of plastic (there are also tinplate, but now there are very few) as big as a mouth of the sea bowl.

Luan only needs to dig a hole the size of a fist in the northwest wall of the city building (the base of the stormwater pipe hanging) and connect it with the stormwater pipe. Then he can pick up the goods on the ground.

Setting it at the entrance of the cave is six meters to prevent good people from consuming water. It will prevent people from throwing garbage into the cave and killing mice.

When connecting the hole in the wall to the rainwater pipe, Lu An didn't want to jump six meters high, which surprised the people around him. He bent down and took things from the exit of the rainwater pipe to get things more low-key.

These small containers passing through the ground are metal, and in layman's terms, they are transformed from cans. Therefore, the pipelines on these underground sliding rails are not large.

Now Lu'an builds a ground grid transportation line to set the diameter of the underground transportation pipeline by considering the diameter of the can. Because cans are the easiest metal containers to obtain. When using cans directly, Lu'an does not need to make waterproof and moisture-proof containers specifically for underground logistics. Moreover, even the containers made of waterproof paper are not as strong as metal containers.

Sometimes industrial standards are based on basic considerations. The diameter of the American rocket engine design must be considered in terms of train track width, and the width of the train track inherits the standards of Roman roads. At this time, the diameter of the can determines the standards of this underground project.

So the camera cuts to Lu'an. In reality, Lu'an is carrying a bag and walking around with meals, but in the preview, he is active in various parts of the street, using super-guided power to explore the underground and feed the information back to reality. In reality, Lu'an controls hundreds of unresisting film-free glass-textured drill bits underground to drill. Glass texture tools represent that the micro factories in Lu'an already have high-pressure waterjet cutting technology.

Yes, in clusters, Luan can push down the entire building in an instant, that is, the damage caused by the rehearsal is broken and fed back to reality, and directly implant the unresisting membrane, allowing its internal structure to slide directly under gravity and then collapse.

However, now Lu An did not use his superpower to destroy it. Instead, he was building it. Of course, a certain rehearsal emotional state complained that it was illegal to build it. But no emotional state took this joke to heart. It was illegal? Yes, is it illegal? Is it illegal? Is it illegal? Is it illegal? Is it illegal? There are hundreds of robberies in this city every day, and I have not seen the police arrest it.

Lu An, who strictly abides by the rules, is more likely to be ashamed than ordinary people, but it is by no means dogma. Just as farmers are simple, it does not mean that farmers are stupid.

All Luan's rehearsals were not ashamed. Instead, they were full of passion, and they shattered pipes on the underground of this city and on the foot of the walls. Destroy public property or something? Yes, if this society has the ability to prevent everyone from destroying public property, Luan would naturally abide by the rules, because it is beneficial to himself to implement the rules thoroughly.

However, this rule cannot be implemented, and the public security in every corner is extremely poor. Lu An will naturally set new codes of conduct for himself to adapt to this society.

In reality, Lu An's backpack is full of various packaging boxes, and he probably will have to eat these things in the next three days.

Underground, all the excavated slags in the project are crushed and kept throwing them into the sewer.
