Compared to satellites in the sky, drilling holes and building bridges looks very rustic, but once this kind of huge amount of work is completed, it is the most proud of people.

How much is Lu An's conductive superpower, the standard of the fifth level is a conductive area of thousands of cubic meters. When he met Ji Liu, Lu An tested his conduction super energy of about 3,000 cubic meters. As for now, Lu An can't accurately calculate, but the preliminary estimate should be more than 5,000 and less than 12,000.

It didn't take much to lay out the sky network, and most of the sky network lines were only a tenths of a millimeter in diameter and as thin as a human hair. One cubic meter can lay a million meters, a thousand kilometers, and Lu An consumed a total of five hundred cubic meters of super energy to lay such a sky net in the sky.

The densest lines in this large net were only 300 meters apart, because the deviation of Lu An's planes from normal navigation on each channel was up to 100 meters. This large net gives the initial positioning, and the gyroscope in the aircraft can also perform detailed positioning. So it's basically satisfying Luan's sky armed deployment.

This Skynet can also transmit information, relying on mechanical waves to transmit information, and it has practical value in the advance of the rehearsal for nine minutes. But at present, it is very inconvenient to rely on Skynet to transmit information.

Because Skynet is mostly at an altitude of 500 meters. In reality, Lu An is on the ground, even if it is a rehearsal, Lu An is mostly acting on the ground, and it is impossible to fly to the sky casually, and now Lu An's rehearsal is as long as nine minutes, and after taking off in these nine minutes, basically don't do anything next, wait to be watched and ask for autographs. This seriously affected the efficiency of his work in the rehearsal.

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

In the rehearsal, if Lu An wants to read the information, he only needs to stand a little, take out a nail from his pocket, wrap it in an unobstructed film, borrow kinetic energy from the car on the street, and run the nail through dozens of meters underground to connect to the ground network. Such a small movement, no one will notice. Even if Lu An finishes the calculation and raises his foot, someone will see this small hole and think that it is already there. It should be left by rain erosion, as for how deep this hole is, there will be nine minutes of rehearsal time, and no one will take an excavator to drill down and investigate the root cause. As long as no one checks, Lu An can do other things in the rehearsal.

In this way, on the ground, Lu An can interpret the seismic wave information through the bubble computer he carries with him, and understand the situation of the aircraft cruising along the sky along the skynet.

Of course, the ground network is not only used to transmit information, Lu An feels that it should also have a certain material transportation capacity, and it is not necessary to transport itself, and he can fly anyway when he encounters danger, but in normal times, it is very good if he can transport something the size of a can to his position.

So Luan's plan is, pipeline and rail plan. and the setting of storage points at various points in the city.

The pipeline is a one-millimeter main line and a No. 2 pipeline of 0.5 millimeters. It is mainly used for the transmission of powder particles. Generally coal dust and metal powder (explosion is art, high temperature is achievement. Coal dust explodes, aluminum powder and iron powder ignite, and you can't throw fireballs to become a magician. In Luan's plan, 42 cubic meters of main lines were to be used, that is, 420 kilometers of main lines would be laid to connect 400 main storage points. On average, there is one within 700 meters.

Each main storage point is 40 meters underground, there are multiple cavity groups inside, the cavity group is 8 cubic meters, and the internal cavity wall is covered with an unobstructed membrane. ）

Each primary storage site has a number of sub-storage points ranging from sixteen to twenty-seven. Basically, you can run a hundred meters, and there is an ammunition depot at your feet. Since escaping from the first generation, Luan believes that fighting is all about using everything that can be used. If you can stab with a knife, you don't need to have a big fist, and if you can fry it with powder, you don't need to bomb it with super energy.

These sub-storage points are planned, with multiple pipes extending to the surface, remember that there are many, a water tower can have multiple taps, and a storage point can have multiple pipes extending to the ground. Lu An's ideal state is a twenty-meter walk in the city, and there is a small hole in the diameter of a straw in the wall three meters high, so that he can bring up the powder he wants. As for why the walls are three meters high? At a height of three meters, no one will touch it casually. It can be arranged in the streets and alleys. As for the fact that someone sees a small hole in the cracks of these bricks that can only be inserted with a straw, they will not be driven by curiosity to smash the wall.

As for the number of pipes from the underground storage point to the surface is too large and too long, Lu An will not arrange it and maintain it every day to keep it permanently unobstructed. If you want to arrange, it consumes too much.

Because when you get to this place, you can use Frog Vision to temporarily add an unobstructed film to this last pipe. It's also time to get through when needed.

It's like taking a bus home and sitting at the station, just walking back a few steps from the platform to the door of the house, and you don't need to build an electric sidewalk to send yourself home.

Finally, these pipes are numerous and large, not to mention, and have a large diameter (the thickness of the straw). If it is arranged at all times, Lu An's guiding power super is not enough.

And the temporary arrangement is very fast, when Lu An has a need in reality, he can send a rehearsal to fly over, through the frog vision, quickly unobstructed the pipe on the wall, and then can spray powder on a large scale. In reality, Lu An didn't even have to move, as long as he saw what he saw (what he saw in the rehearsal), he could control the powder stored underground from several kilometers, or even ten kilometers away, to flow out of the surface.

This is the pipeline plan in the network.

As for the rail plan, it can transport some gadgets, such as a moon cake, a box of Yunnan Baiyao, a magnifying glass, and a watch. A telescope, these don't take up space, but you can't take it with you, and it's very far away to get it home.

The powder was transported to prevent accidents, and it was up to Luan to save himself the trouble of transporting these things.

Lu An put it in the words of an emotional state: "In order to build a pipeline to transport the powder, all have been excavated underground, why not dig a larger one to accommodate a small box to pass through?" After this small box is wrapped in an unobstructed film, it can move around the city with very little energy as long as it leans on this ready-made slide. ”

Although there are many people in this city, there are always blind spots, such as the north side of a building (the side without a balcony). It's dark all year round, and people only park their bikes in the morning, and it's as empty as the school hallway during classes. Sometimes, these dark corners will be poured with urine because people who are anxious and can't find the toilet.

Materials so export, there are ready-made, modern buildings every building has rainwater drainage pipes, please note that the four corners of the building are round, the external pipes, hanging from the roof to the ground, plastic (there is also white iron, but now there are very few) sea bowl bowl mouth is so big.

Luan only needs to dig a fist-sized hole in the northwest wall of the city building (the base of the wall where the storm sewer pipe hangs) and dock it with the storm sewer. You will be able to pick up the goods on the ground.

It is set at six meters from the entrance of the cave to prevent good deeds, and to pour water into the hole to prevent people from throwing garbage into the hole and throwing dirty things such as dead rats.

And connecting the hole in the wall to the rainwater pipe, Lu An didn't want to jump six meters high and surprise the people around him. It's a little more low-key to bend down and pick up something from the storm drain exit.

These small containers that travel underground are metal, or in layman's terms, cans are repurposed. So the pipelines for these underground slides are also not large.

At present, Lu'an is building a network transportation line to set the diameter of the underground transportation pipeline by taking into account the diameter of the cans. Because cans are the most readily available metal containers. With direct access to cans, Luan does not need to be specially made as a waterproof and moisture-proof container for underground logistics. And even if Lu Ann made a container of waterproof paper, the strength is not as good as that of a metal container.

Sometimes industry standards are based on foundational considerations. The design diameter of the rocket engine in the United States took into account the width of the train track, which inherited the standard of the Roman road. At this time, the diameter of the can determines the standard of this underground project.

So the camera cuts to Lu An, in reality, Lu An is carrying a bag and shopping for a meal, but in the rehearsal, one by one, he is active in various parts of the street, using his guiding power to explore the underground and feed back the information to reality, and in reality, Lu An controls hundreds of drill bits wrapped in unobstructed film glass in the underground to drill. The glass texture tool means that the micro-factory in Lu'an already has the cutting technology of high-pressure waterjet.

Yes, in the cluster state, Lu An can flatten down the entire building in an instant, that is, the fracture surface caused by the destruction in the rehearsal, feedback to reality, and directly implant the unobstructed membrane, so that its internal structure slides directly under gravity, and then collapses.

However, now Luan didn't use his super power to destroy. It's construction, of course, a rehearsal emotional state complains that this is an illegal construction, and it is illegal. But there is no emotional state that takes this joke to heart and breaks the law? Yes, it is indeed illegal? Is it illegal to rob or to break the law? Every day there are hundreds of robberies in the city, and the police are not seen to arrest them.

Lu An, who strictly abides by the norms, is easier to be ashamed than ordinary people, but it is by no means dogmatic, just like farmers are simple, but it does not mean that farmers are not careful.

Luan was not ashamed of all the rehearsals. Rather, it is full of passion, smashing pipes one by one under the city and at the foot of the walls. Destroying public property or something? Yes, if this society is capable of preventing everyone from destroying public property, Luan will naturally abide by the rule, because it is in his own interest to implement this rule thoroughly.

However, this rule cannot be implemented, and the law and order in all corners is extremely poor. Naturally, Luan will set a new code of conduct for himself to adapt to this society.

In reality, Lu An's backpack is already full of various packing boxes, and it is estimated that he will have to eat these things for the next three days.

Underground, all the excavated slag in the project is crushed and continuously thrown into the sewer.

If there is more sand in the water quality of the sewers, if there is such a study, there will be signs that Luan is engaged in construction. But the sewer workers will look into this? It is also impossible for the Tiger Department to send personnel to monitor the water quality of the sewers. They don't have the money and they wouldn't have thought of the situation here. I wouldn't have thought that Lu An would not go to participate in the Huashan Sword Debate of the Superpowers, but would be idle and do this kind of thing on the streets.
